Property Disclosures topic guide
Environmental and government disclosures
Environmental questions become manageable when you stop treating every hazard as the same kind of rule. Lead, radon, flood mapping, asbestos, tanks, contamination, and violation notices each have their own evidence, timing, and professional lane.
Last reviewed:
The short answer
Match the hazard to the required document and delivery deadline, then separate disclosure from investigation and cleanup. Covered pre-1978 housing needs the federal lead package before obligation; a buyer’s written inspection waiver does not waive required disclosures. Covered Illinois sales have separate seller-report and radon duties. A Phase I assessment is not automatically a lead, mold, radon or asbestos survey. A removed tank or an NFR letter is not a promise that every use is safe or unrestricted. Communicate known facts and actual records, and use the appropriate professional for testing, legal consequences and technical conclusions.
The June 24, 2026 PSI outline places environmental and government disclosures in National VII.B. The whole Property Disclosures category has 7 of the 100 scored national broker questions, not a quota for this page. Coverage and exclusions differ across the federal lead rule, Illinois residential report, radon sale and rental provisions, mine-subsidence law and cleanup programs. Examples assume a covered transaction unless they ask you to determine a particular boundary. No practice score here is a validated readiness cutoff.
Match each concern to its document and deadline
- Identify the property, transaction and actual concern. A residential sale, lease, commercial acquisition and redevelopment can trigger different requirements.
- Determine coverage under each applicable rule. Do not borrow an exemption, form or deadline from another environmental law.
- Gather knowledge and records: reports, test results, earlier mitigation, flooding, claims, notices, permits, agency correspondence and recorded controls. “No knowledge” is not a professional finding that the concern is absent.
- Deliver the required package on time. Federal lead and covered radon-sale information must be complete before obligation; their post-offer rules require completion before acceptance and an opportunity to review and amend. The Illinois seller report has its own before-signing rule.
- Set the investigation scope with the appropriate professional. A home inspection, lead evaluation, licensed radon measurement, asbestos evaluation, Phase I and Phase II answer different questions.
- Protect actual contract rights and dates. Do not assume a statutory lead opportunity creates every other inspection, financing, insurance or termination right, or that a late signature cures a missed disclosure.
- Verify the status and scope of agency documents. Read the actual notice or closure letter, its property description, restrictions and recording requirements rather than relying on an invoice, database label or verbal assurance.
- Keep accurate evidence of delivery, acknowledgments, agreed changes and decisions. Never backdate a form or describe a disclosure, database result or assessment as a guarantee.
| Concern | Core document or source | Separate investigation |
|---|---|---|
| Most pre-1978 housing | Federal lead pamphlet and disclosure | Lead inspection or risk assessment |
| Illinois residential sale | Radon pamphlet and Illinois radon form | Licensed radon measurement |
| Known residential defects | Illinois seller disclosure report | Inspection and specialist reports |
| Suspect asbestos material | Seller knowledge and actual reports | Appropriately qualified evaluation; no broker sampling or visual diagnosis |
| Former gas station | Agency files and Phase I assessment | Phase II sampling if warranted |
| Removed underground tank | OSFM and Illinois EPA records | Release status and closure review |
| Flood concern | FEMA map and local floodplain records | Elevation, insurance, lender, and history review |
| Possible mine subsidence | Mine maps, seller history, claims, DNR information | Engineering and insurance review |
| Lead evaluation opportunity | Normally 10 days for the purchaser | Written different period or written waiver; disclosures remain |
| Lead records | Available includes possessed or reasonably obtainable | Common-area and qualifying building-wide reports matter |
| AAI timing | Within 1 year before acquisition | Five components within 180 days before acquisition |
| AAI standards in October 2026 | E1527-21 and E2247-23 | Older recognized-version cutoff dates have passed |
| Phase I scope | Defined inquiry with limits and data gaps | Non-scope hazards and extra services need an actual scope |
| NFR letter | Program-specific closure and conditions | Read restrictions, recording and continuing controls |
| Mold | Moisture history and observed condition | No federal indoor-mold passing concentration |
| Government violation notice | Actual received notice and correction evidence | A report asks about uncorrected violations, not every old corrected notice |
The distinctions that matter
| Distinction | How it works | What to notice |
|---|---|---|
| Disclosure vs. testing | Disclosure communicates required information, knowledge, and records. Testing measures or samples a condition under an appropriate protocol. | Tell what is known versus investigate what is present. |
| Testing vs. mitigation | Testing identifies or measures a concern. Mitigation or remediation reduces, contains, removes, or manages it. | Find the condition versus address the condition. |
| Lead pamphlet vs. lead disclosure form | The pamphlet provides general hazard education. The transaction disclosure communicates property-specific knowledge, records, warning language, and acknowledgments. | General education versus property-specific certification. |
| Lead disclosure vs. 10-day evaluation opportunity | Disclosure delivers information and records. The evaluation period gives a buyer time to obtain an inspection or risk assessment, subject to written agreement or waiver. | Receive information versus investigate the housing. |
| Radon disclosure vs. radon mitigation | Illinois disclosure communicates the warning and known records. Mitigation is licensed technical work to reduce elevated levels. | Required notice versus corrective system. |
| Phase I vs. Phase II environmental assessment | A Phase I primarily uses records, history, observations and professional inquiry. Phase II generally investigates concerns through sampling or testing. Do not call sampling a mandatory part of every Phase I or say AAI can never involve it: Section 312.20(g) permits sampling and analysis to address data gaps, and additional services can be separately agreed. | Inquiry and professional opinion versus physical investigation data. |
| Tank removal vs. cleanup closure | Removal addresses equipment. An Illinois EPA closure document has a specific program and release or site scope, with applicable controls and recording conditions. Neither a tank invoice nor a conditional NFR letter guarantees unrestricted residential use or absence of every contaminant. | Container gone versus release resolved to agency standards. |
| Flood map vs. flood history | A flood map shows modeled hazard zones. Property history concerns actual water events, claims, drainage, and repairs. | Mapped risk versus experienced event. |
| Government database hit vs. final conclusion | A database entry is a screening lead. The underlying agency file, location accuracy, status, technical work, and legal review determine significance. | Reason to investigate versus proof of current liability. |
| Written lead-evaluation waiver and required disclosures | A purchaser may waive the evaluation opportunity in writing. That does not waive the required pamphlet, known information, available records, warning and acknowledgment package. | A waived investigation is not erased disclosure. |
| Assessment cover date and dates of the work | AAI has a one-year acquisition window and five components that must be conducted or updated within 180 days before acquisition. A newer report cover does not automatically update old interviews, searches, inspection or the environmental professional’s declaration. | Check the component dates, not just the report’s title page. |
| Assessment and liability protection | AAI can be a condition of specified CERCLA protections, but it is not the whole defense. Other statutory criteria and continuing obligations remain. A qualified bona fide prospective purchaser can knowingly acquire contaminated property; that is not automatic immunity. | Required inquiry versus the entire legal protection. |
| Federal paint rule and other lead-related duties | The transaction rule concerns lead-based paint and related hazards. It does not certify drinking-water or service-line conditions, replace renovation-safety requirements, or cancel applicable state and local notice duties. | Name the hazard and legal layer accurately. |
| CERCLA petroleum exclusion and all environmental obligations | CERCLA’s hazardous-substance definition generally excludes petroleum unless specifically listed or designated. That does not erase Illinois tank and release requirements or turn every former gas station into a risk-free site. | One definition is not an exemption from every law. |
Work through the facts
The lead form arrives after the buyer signs
A buyer signs a contract for a 1925 house. The next day, the listing broker sends the federal lead pamphlet and disclosure form and asks the buyer to acknowledge receipt.
- Most pre-1978 housing is target housing unless an exemption applies.
- The required activities generally occur before the purchaser is obligated, and late disclosure calls for legal and broker review rather than simple backdating.
Answer: Escalate immediately to the sponsoring broker and the parties' attorneys, provide the complete information accurately, and do not alter dates or imply that a late signature cures every consequence.
The seller never tested for radon
An Illinois seller says there are no radon records because the home was never tested. The buyer asks whether the seller must install a mitigation system before closing.
- The Illinois Act requires the approved pamphlet and disclosure for a covered sale and communication of specified knowledge and records.
- It does not create a general duty to test or mitigate, while the contract may give the buyer testing and negotiation rights.
Answer: Deliver the required materials, preserve the buyer's test decision and deadline, and avoid inventing a statutory mitigation requirement.
The tank was removed, but the file remains open
A commercial seller provides a tank-removal invoice. The Illinois EPA database identifies a reported release, and no No Further Remediation Letter appears in the file supplied to the buyer.
- Tank removal and corrective-action closure are different events.
- A purchase may carry cleanup, lender, redevelopment, insurance, and liability consequences requiring environmental and legal review.
Answer: Obtain the agency file and environmental professional's assessment before the due-diligence deadline. Do not describe the site as clean based on the invoice.
A dry basement is inside a mapped flood zone
The seller reports no known flooding, but FEMA mapping places part of the property in a Special Flood Hazard Area and the lender asks for flood insurance.
- No known prior event does not erase modeled flood risk or lender requirements.
- Map location, building elevation, local regulation, coverage, cost, and any map amendment must be evaluated through their proper sources.
Answer: Provide the seller's statement accurately while the buyer confirms mapping, lender, elevation, local, and insurance facts before waiving the applicable contingency.
Waiving an evaluation is not waiving disclosure
For a covered pre-1978 sale, the buyer signs a written waiver of the lead evaluation opportunity. The seller proposes withholding known lead reports and the pamphlet as well.
- The written waiver addresses the inspection or risk-assessment opportunity.
- The pamphlet, known information, available reports and required contract language have separate duties.
- A buyer’s waiver does not make a late, incomplete or withheld package compliant.
Answer: Provide the required disclosure package; the written evaluation waiver does not erase it.
A tile is not a laboratory result
During a showing, an agent sees old floor tiles and proposes breaking off a piece to prove whether asbestos is present.
- Appearance generally cannot identify asbestos content.
- Disturbing or incorrectly sampling suspect material can release fibers.
- Use an appropriately qualified professional and the applicable project and jurisdiction requirements rather than broker sampling.
Answer: Describe the observed material and arrange appropriate evaluation; do not disturb it to make a broker diagnosis.
Fresh paint over a recurring moisture problem
A wall with a history of water intrusion has been painted. There is still a damp odor, and the seller offers a single favorable air sample as proof of federal mold compliance.
- Painting does not establish that the water source was corrected.
- The history, odor and current moisture require investigation within an appropriate scope.
- EPA reports no federal numerical mold or spore limits that make this sample a federal passing certificate.
- Do not diagnose a person’s health or a mold species from a showing.
Answer: Investigate the moisture source and actual repair history; do not promise federal mold clearance.
A Phase I with a limited engagement
A buyer receives a Phase I report whose scope does not include a radon measurement, asbestos survey or lead-paint evaluation, then assumes all three hazards have been tested and ruled out.
- The report’s actual scope controls what work was performed.
- These can be non-scope considerations or separately commissioned services.
- Phase I findings and data gaps are not a universal environmental warranty.
Answer: Identify the missing specialist scope before relying on the report for those separate hazards.
The report is newer than the visual inspection
At the proposed acquisition, a report cover is 100 days old, but its unchanged visual inspection occurred 200 days before acquisition. Assume the buyer seeks to rely on AAI and no later update of that component occurred.
- The overall inquiry has a one-year requirement.
- The visual inspection is also one of five components that must be conducted or updated within 180 days before acquisition.
- A 100-day-old cover does not turn a 200-day-old inspection into updated work.
- Have the environmental professional address the necessary updates and the rest of the actual requirements.
Answer: The stipulated visual-inspection component needs an applicable update; the cover date alone does not satisfy its 180-day condition.
Commercial closure does not approve a residence
An Illinois EPA NFR letter restricts the site to commercial or industrial use and prohibits using groundwater for drinking. A buyer proposes homes and private drinking-water wells without reviewing those conditions.
- The letter’s program, scope and continuing conditions matter.
- The proposed uses conflict with the stipulated restrictions.
- A letter is not a blanket guarantee for every redevelopment.
- Do not infer from an older supplemental-letter example that a UST site can simply transfer into the SRP; the current agency page expressly bars that transfer.
Answer: Obtain environmental and legal review of the actual restrictions and any lawful change process before relying on the proposed use.
The paid mine claim has its own document and timing
Assume a covered transfer under the Illinois Mine Subsidence Disclosure Act, a claim paid to the transferor and no statutory exclusion or waiver changing the result. The seller plans to mention the claim orally to the buyer only at closing.
- The stated separate Act requires writing to both the transferee and lender.
- Its timing is at the agreement, with disclosure incorporated in the written transfer agreement.
- An oral comment at closing does not supply the stated recipients, writing or timing.
- The Act permits a written waiver by both transferee and lender; neither a presumed waiver nor the buyer alone waives the other recipient’s requirement.
Answer: Use the required written disclosure at the agreement on the stipulated facts; do not replace it with a late oral comment.
Mitigation does not erase possessed records
For a covered Illinois sale, a seller possesses an earlier elevated radon test and later mitigation records. The seller asks to describe the home as never having had elevated radon because a system was installed.
- Past elevated information and present mitigation are different facts.
- The statutory sale package addresses the required knowledge and applicable possessed reports.
- Explain the actual mitigation information without erasing the earlier results.
- A system’s presence alone is not a current concentration test or a future health guarantee.
Answer: Provide the applicable records and describe the present information accurately; do not rewrite the property’s history.
Mistakes to avoid
- Federal lead disclosure applies to every property built before 1978 without exception. The rule covers most pre-1978 target housing but lists transaction and housing exemptions that must be checked.
- Lead disclosure requires every seller to test and remove lead paint. The disclosure rule communicates known information and records and provides an evaluation opportunity; testing and hazard reduction are separate questions.
- The buyer always has exactly 10 days and cannot change it. The standard opportunity is 10 days, but the parties may agree in writing to another period and a buyer may waive it in writing.
- Illinois radon disclosure proves the house is safe. The form communicates warnings and knowledge. Only proper measurement supplies a current concentration result.
- A broker can identify asbestos by looking at a tile. Appearance may raise suspicion, but identification and sampling belong to qualified professionals.
- A mold air sample is always the only useful first step. EPA emphasizes moisture control and notes that visual assessment and water history often guide the response; professional scope depends on the facts.
- A tank-removal receipt proves there was no release. Tank work and contamination status require separate records and, where warranted, environmental investigation.
- A Phase I guarantees that no contamination exists. A Phase I is a defined inquiry with opinions, limitations, data gaps, and possible recommendations, not a universal guarantee.
- A property outside a mapped high-risk flood zone cannot flood. Mapped zones express modeled hazard, not a promise that water cannot affect other property.
- A government notice can be summarized from memory and discarded. The actual notice, issuer, property, violation, dates, orders, status, and correction evidence should be reviewed and retained as appropriate.
- A written waiver of the lead inspection removes the disclosure package. It waives the evaluation opportunity only. Required information, pamphlet, available records and contract language still apply.
- Every certified lead-free finding creates an exemption from every sale and lease. The specific certified lead-free exemption in Section 745.101(b) concerns leases. Do not expand it into a blanket sale exemption.
- A current report cover makes every AAI component current. Check the dates of the actual work and the five 180-day components, including the environmental professional’s declaration.
- A standard Phase I automatically evaluates every indoor hazard. Lead paint, mold, radon and asbestos can be non-scope considerations or additional services. Read the engagement and report rather than assuming coverage.
- An NFR letter permits any future use without conditions. An NFR letter may impose use, groundwater, engineering or institutional controls. Verify its scope, recording and continued conditions.
- A favorable mold sample is a federal safety certificate. EPA reports no federal limits for mold or mold spores. Investigate the moisture source and actual conditions; do not invent a federal passing count.
- An old UST fact sheet proves the current deductible or automatic fund eligibility. Use current applicable law and the actual eligibility decision. The older buyer sheet is used here for records and owner-election cautions, not a 2026 fee or deductible table.
Check your understanding
These are original teaching questions, not recalled or predicted PSI questions. Answer first, then explain why the other choices fail.
1. Before a buyer is obligated to purchase most housing built before 1978, what must the seller generally provide under the federal lead rule?
- The approved pamphlet, known information, available reports, and required warning and acknowledgment language
- Only a verbal statement that the paint looks sound
- A mandatory full abatement certificate for every home
- A guarantee that no lead exists
Show answer and explanation
Answer: A. The approved pamphlet, known information, available reports, and required warning and acknowledgment language
The federal rule focuses on timely information, records, warnings, certifications, and the buyer's evaluation opportunity.
2. Under the Illinois Radon Awareness Act, which statement is most accurate for a covered residential sale?
- The Section 26 tenant package always replaces the sale document
- Every EPA testing recommendation becomes a mandatory seller mitigation duty
- A buyer’s lead-evaluation waiver removes the separate radon package
- The seller provides the approved pamphlet and disclosure, but the Act does not generally require testing or mitigation
Show answer and explanation
Answer: D. The seller provides the approved pamphlet and disclosure, but the Act does not generally require testing or mitigation
Illinois requires the specified education and disclosure materials while expressly separating that duty from mandatory testing or mitigation.
3. A Phase I environmental site assessment primarily does which of the following?
- Collects laboratory soil and water samples in every case before reviewing records
- Evaluates environmental conditions through records, history, observation, and professional inquiry
- Certifies the site for every future use and all regulatory purposes
- Automatically replaces separate lead, radon and asbestos specialist scopes
Show answer and explanation
Answer: B. Evaluates environmental conditions through records, history, observation, and professional inquiry
All Appropriate Inquiries evaluates present and past property conditions and potential releases under a defined professional process.
4. A seller produces proof that an underground tank was removed, but a reported release remains in the Illinois EPA record. What should the buyer investigate?
- Assume physical removal alone settles all release and liability questions
- Corrective-action status, agency files, environmental findings, and any closure document
- Assume every future cleanup cost is automatically reimbursed from the UST Fund
- Treat only the removal invoice as complete cleanup closure
Show answer and explanation
Answer: B. Corrective-action status, agency files, environmental findings, and any closure document
Removal of equipment does not establish that a release was fully investigated or closed under the applicable program.
5. Which statement correctly distinguishes a disclosure from a test?
- Waiving an investigation always waives mandatory disclosure
- Completing mitigation automatically makes every earlier possessed report unavailable
- A disclosure form measures a current concentration without testing
- Disclosure communicates required knowledge and records; testing investigates or measures a condition
Show answer and explanation
Answer: D. Disclosure communicates required knowledge and records; testing investigates or measures a condition
Keeping notice, investigation, and remediation separate is the key to this exam topic.
6. A purchaser waives the lead evaluation opportunity in writing for a covered sale. Which duty remains?
- The required disclosure package, including known information and available reports
- Only a guarantee of lead-free paint
- Only a verbal warning if requested at closing
- No lead-related duty remains
Show answer and explanation
Answer: A. The required disclosure package, including known information and available reports
The written evaluation waiver is not a waiver of the separate disclosure, pamphlet, records and contract requirements.
7. Does the federal lead-disclosure rule automatically give a renter the purchaser’s 10-day evaluation opportunity?
- Yes, every lease has the identical purchase right
- No; covered rentals have disclosure duties, while this statutory opportunity is for purchasers
- Yes, but no rental disclosure is required
- No, because every lease of pre-1978 housing is exempt
Show answer and explanation
Answer: B. No; covered rentals have disclosure duties, while this statutory opportunity is for purchasers
Keep sale and rental duties separate. A tenant can request testing or have contractual rights without this purchaser provision automatically applying.
8. Required lead or covered radon-sale information is first provided after the buyer’s offer. What do the stated post-offer rules require?
- Accept first and allow review only afterward
- Complete the disclosure before acceptance and allow review and possible amendment
- Wait until after closing
- Backdate the buyer’s acknowledgment
Show answer and explanation
Answer: B. Complete the disclosure before acceptance and allow review and possible amendment
The post-offer provisions do not authorize accepting first and supplying the package later. Each law’s actual coverage and complete requirements still matter.
9. Which list includes all five stated AAI components subject to the 180-day acquisition timing requirement?
- Only soil sampling, paint sampling and a radon test
- Interviews, cleanup-lien searches, government-record reviews, visual inspections and the environmental professional’s declaration
- Only the report cover and title-insurance commitment
- Every possible environmental task with no separate one-year rule
Show answer and explanation
Answer: B. Interviews, cleanup-lien searches, government-record reviews, visual inspections and the environmental professional’s declaration
Section 312.20 lists those five components. Check the work and update dates; do not omit the professional’s declaration.
10. Which ASTM editions are identified in the current AAI references for October 2026?
- E1527-21 and E2247-23
- Only E1527-13, because the newest standard is never recognized
- E1527-13 and E2247-16 without time limits
- Every past edition forever
Show answer and explanation
Answer: A. E1527-21 and E2247-23
The regulation identifies these current editions. The older listed editions had cutoff dates in 2024 and 2025 that have already passed; no complete paid ASTM text was read for this guide.
11. Does a standard Phase I engagement automatically prove that lead paint, radon, mold and asbestos were all tested?
- Yes, those tests are necessarily included in every Phase I
- Yes, if the cover says environmental assessment
- No; review the actual scope and any agreed additional services
- No, because no professional can ever assess those hazards
Show answer and explanation
Answer: C. No; review the actual scope and any agreed additional services
EPA identifies these as possible non-scope considerations or additional services. A defined inquiry is not an all-hazards survey or warranty.
12. An NFR letter restricts a site to industrial use. What should a residential developer infer?
- The actual scope, restrictions and any lawful change requirements need review
- The letter removes every future land-use condition
- The original restriction can be ignored if the tank is gone
- Every residential use is automatically approved
Show answer and explanation
Answer: A. The actual scope, restrictions and any lawful change requirements need review
Conditional closure is not approval of all uses. Read the letter, recording and continuing controls with the appropriate professionals.
13. What does EPA’s mold guide say about using a sample as proof of compliance with a federal mold concentration limit?
- Every indoor sample below a universal number certifies safety
- Visible growth always requires an air sample before any investigation
- A broker can certify a medical diagnosis from mold color
- There is no EPA or other federal mold or spore limit that supplies that passing count
Show answer and explanation
Answer: D. There is no EPA or other federal mold or spore limit that supplies that passing count
Do not invent a federal passing concentration. Moisture history, current conditions, professional scope and any other applicable requirements still matter.
14. What can an agent generally determine about suspected asbestos solely by looking at a floor tile?
- Appearance alone generally cannot establish asbestos content
- Its exact asbestos percentage
- That immediate removal is universally required for a sale
- That the buyer has no disclosure or investigation interest
Show answer and explanation
Answer: A. Appearance alone generally cannot establish asbestos content
Treat the observation as a reason for appropriate evaluation, not permission for broker sampling or a technical guarantee.
15. Assume a covered transfer triggers the Illinois Mine Subsidence Disclosure Act because a claim was paid to the transferor. To whom and when is the stated disclosure due?
- Only an insurer after recording
- In writing to the transferee and lender at the time of agreement
- Only the buyer at closing
- Only the lender after a new claim
Show answer and explanation
Answer: B. In writing to the transferee and lender at the time of agreement
The separate Act has specific covered-transfer and paid-claim conditions. Do not replace its timing with closing or confuse a mine map with proof of a paid claim.
16. Does a seller’s lack of known flooding establish that a mapped flood concern or lender insurance request can be ignored?
- No; history, current mapping, building location, lender and insurance facts are separate
- Yes, if a general homeowners policy exists
- Yes, a dry showing overrides every map
- No, because every parcel has identical mandatory insurance terms
Show answer and explanation
Answer: A. No; history, current mapping, building location, lender and insurance facts are separate
No known event is not a flood-risk or insurance guarantee. Confirm the actual current sources and applicable conditions rather than making a parcel-wide assumption.
17. Assume no other exception changes the comparison. Which construction year falls within the pre-1978 part of the target-housing definition?
- 1985
- 1978
- 1980
- 1977
Show answer and explanation
Answer: D. 1977
Prior to 1978 includes 1977, not 1978. The year is only one coverage element; the complete definition and transaction exemptions still matter.
18. Under the current Section 745.103 definition, a five-year-old child is expected to live in an otherwise zero-bedroom dwelling. Assuming no other exemption, what does the child condition do?
- Removes this particular zero-bedroom exclusion from target housing
- Creates an unconditional exemption for every studio regardless of children
- Makes all lead disclosures unnecessary because the child is under six
- Requires the broker personally to sample every painted surface
Show answer and explanation
Answer: A. Removes this particular zero-bedroom exclusion from target housing
The current definition’s under-six child condition applies to this zero-bedroom exclusion. Do not repeat a stale unconditional studio exemption or infer a universal testing mandate.
19. Which statement correctly separates EPA’s 4 pCi/L radon action recommendation from the Illinois Section 10 sale-disclosure duty?
- Every covered seller must test and mitigate before listing
- Every result below 4 pCi/L guarantees no health risk
- EPA recommends fixing at 4 pCi/L or more, while Section 10 does not itself impose a general seller test-or-mitigate duty
- The recommendation removes every required radon form
Show answer and explanation
Answer: C. EPA recommends fixing at 4 pCi/L or more, while Section 10 does not itself impose a general seller test-or-mitigate duty
EPA states there is no known safe exposure level and recommends considering action below four as well. The action level, a measurement, the disclosure duty and any specific contract or other legal requirement are separate questions.
20. A seller possesses earlier elevated radon reports and later mitigation information. What is the sound disclosure approach for a covered sale?
- State that no radon ever existed because a system is present
- Provide the required knowledge and applicable possessed reports, explaining current mitigation information accurately
- Destroy the earlier records after installing the system
- Treat the system as a permanent guarantee of future concentrations
Show answer and explanation
Answer: B. Provide the required knowledge and applicable possessed reports, explaining current mitigation information accurately
Mitigation and disclosure are separate. Do not erase possessed elevated reports or misstate present knowledge; a current concentration requires appropriate measurement, not a broker guarantee.
Common questions
What are environmental and government disclosures in real estate?
Separate legally required disclosures from investigation records. A lead package, covered Illinois radon sale package, residential seller report or specific government notice has its own source and timing. A flood map, agency file or environmental assessment can support due diligence without being the same thing as a required signed disclosure form. Determine the property, transaction, knowledge and applicable rule before choosing the document or deadline.
What must be given before the sale of most pre-1978 housing?
For covered target housing, provide the approved lead pamphlet, known lead-based-paint and hazard information, available records and reports, and the required warning, certifications and acknowledgments before obligation. Available includes possessed or reasonably obtainable records, including common-area and qualifying building-wide reports from other units. The purchaser’s evaluation opportunity is a separate requirement. Keep the completed acknowledgment information for at least the federal three-year minimum measured from sale completion; covered leasing records use lease commencement. Other applicable retention requirements remain. Electronic delivery must satisfy the applicable consent and access requirements; do not assume an emailed link alone proves compliance.
How long is the federal lead evaluation period?
A purchaser normally receives 10 days before obligation to conduct a lead-based-paint inspection or risk assessment. The parties may agree in writing to a different period, and the purchaser may waive the opportunity in writing. The disclosure package is not waived by that choice. The rule does not itself require every seller to test or abate, and the purchaser provision is not automatically a tenant’s 10-day right. If required information follows an offer, complete it before acceptance and allow review and possible amendment.
What does the Illinois Radon Awareness Act require in a home sale?
For a covered sale under 420 ILCS 46, provide the approved radon pamphlet and the Section 10 Illinois Disclosure of Information on Radon Hazards before the buyer is obligated. Disclose the specified knowledge and possessed reports, including relevant elevated results; earlier mitigation does not simply erase records. If disclosure follows an offer, complete it before acceptance and allow review and possible amendment. Section 10 does not impose a general seller duty to test or mitigate. Check the Act’s definitions and exclusions rather than assuming every transaction is covered. The separate Section 26 tenant package is not a substitute for the sale document.
Is radon disclosure the same as a radon test?
No. Disclosure communicates required information and existing knowledge or records. Testing measures radon under a defined protocol. Mitigation reduces elevated concentrations. Each is a different step, and Illinois licenses radon measurement and mitigation professionals.
Does a seller have to remove all asbestos before selling?
There is no universal federal sale rule requiring every home seller to remove all asbestos. The Illinois residential report addresses known unsafe asbestos concentrations or conditions for covered sellers. Appearance generally cannot identify asbestos, and condition and planned disturbance matter. Use appropriately trained and qualified professionals for evaluation and handling, with actual federal, Illinois and local requirements checked. EPA’s recommendation to use trained, accredited professionals is not a claim that federal law imposes that credential on every detached single-family project. Do not sample or disturb suspect material as a broker.
Is every environmental concern visible during a showing?
No. Radon has no visible signal, contamination may be underground, flood history may not be apparent in dry weather, and former industrial use may be discoverable only through records. A showing complements but never replaces disclosure documents, public-record review, inspections, testing, and environmental due diligence.
What is a Phase I environmental site assessment?
A Phase I primarily examines records, history, observations and professional information under a defined scope. It is commonly used in commercial or higher-risk transactions and can help satisfy AAI conditions for specified CERCLA protections. It is not a contamination-free warranty, cleanup, title search or automatic survey of every indoor hazard. Phase II generally adds sampling or testing to investigate concerns. Avoid the absolute claim that AAI can never involve sampling: Section 312.20(g) permits sampling and analysis to address data gaps. Read the actual engagement and additional services. A real estate broker license alone does not establish the environmental-professional qualifications.
What should a broker do with a government violation notice?
Obtain the actual notice and its issuer, property description, stated violation, dates, status and correction evidence. Communicate accurately, protect the actual contract dates and use appropriate legal or technical review rather than estimating compliance or repair cost from memory. The Illinois report asks about a received notice of a violation that has not been corrected; it is not an instruction to call every old corrected notice an existing violation. The report is not a warranty or a substitute for investigation, and required corrections or written supplements must follow the applicable rules. An “as-is” label does not by itself remove applicable statutory disclosures.
Are these real PSI exam questions?
No. They are original teaching questions aligned with the public June 24, 2026 Property Disclosures outline. No score here is a validated readiness cutoff, pass probability or promise. Explain the applicable document, deadline, scope and decisive fact, then solve a changed scenario. The whole category’s seven-question national allocation is not a quota for environmental questions.
How current must AAI be, and which ASTM editions are recognized?
The inquiry must be conducted or updated within one year before acquisition. Five components must be conducted or updated within 180 days before acquisition: interviews; environmental cleanup-lien searches; government-record reviews; visual inspections; and the environmental professional’s declaration. A newer cover date does not update old work. Current references identify E1527-21 and E2247-23; the older listed E1527-13 and E2247-16 cutoff dates have passed by October 2026. This guide uses the public regulation and EPA synopsis, not the full paid standards. AAI alone does not establish every liability-protection criterion or continuing obligation.
Does tank removal or an NFR letter prove a site is clean?
No. Tank removal, investigation and regulatory closure are separate. Read the actual Illinois EPA letter’s program, release or site scope, land-use and groundwater restrictions, recording and continuing controls. An NFR letter is not unrestricted approval for every redevelopment or a guarantee about every contaminant. The current agency page expressly bars transferring a UST-regulated site into the SRP; an older general supplemental-letter example does not override that statement. Separately, the older buyer fact sheet’s owner election can carry responsibilities and liabilities and is described as irrevocable once filed. It is not a routine records-request form, a funding guarantee or a current deductible table.
Can a property outside a mapped high-risk area still have a flood issue?
Yes. Mapping, actual flood history, drainage, repairs, building location, lender conditions and insurance are separate information sources. A dry showing or no known prior event is not a promise of no future flooding. Use current official FEMA and local records for the actual property; a general state map overview is not an October 2026 parcel determination. Most ordinary homeowners and renters policies do not typically include flood coverage, so check the actual NFIP or private policy and lender terms without promising universal coverage or a waiting period.
Is a mine map the same as an Illinois mine-subsidence disclosure?
No. A map or ground-movement concern calls for appropriate records, engineering and insurance review; it does not prove a paid claim. The separate Mine Subsidence Disclosure Act has covered-transfer conditions and exclusions. When its paid-claim-to-transferor rule applies, the disclosure is in writing to the transferee AND lender at the time of agreement and is incorporated into the written transfer agreement. The residential seller report can separately require knowledge of relevant conditions. Do not reduce all mine-related disclosure to one map or assume no paid claim means no other duty. The Act allows a separate written waiver by both the transferee and lender; do not assume one recipient’s choice waives the other’s requirement.
Is mold sampling always required, and is there a federal passing count?
No. EPA says sampling is generally unnecessary when visible mold growth is present, and there is no EPA or other federal mold or spore limit that supplies a universal passing concentration. Moisture control, actual repair history and the appropriate investigation scope matter. This does not mean every local, contract, workplace or other requirement disappears, or that color or one sample establishes a medical diagnosis. Use the appropriate professionals for technical or health questions.
Do the same lead and radon documents apply to a sale and a rental?
Do not assume that. Covered rentals can require the federal lead package, but the federal 10-day evaluation opportunity is a purchaser provision. The lead rule has specific lease exceptions and renewal conditions; a certified lead-free lease exception is not a blanket sale exemption. Illinois separately uses the Section 10 radon sale document and the Section 26 tenant package, with their own coverage, exclusions and conditions. Use the actual current form for the transaction rather than substituting a tenant form from a link labelled for general real estate use.
Does a radon level below 4 pCi/L prove a home is safe?
No. EPA recommends fixing homes at 4 pCi/L or more and considering action between 2 and 4 pCi/L, while stating there is no known safe exposure level. That is not a broker certification, a guarantee about a particular test or an automatic Section 10 seller duty to test or mitigate. Applicable Illinois definitions, rental provisions, contracts or other requirements have their own conditions; do not derive an individual legal remedy from this short comparison.
Can old environmental reports be ignored after mitigation or repair?
Do not assume so. Required disclosure can include applicable known information and available or possessed reports even when later mitigation explains the current status. The radon sale form separates the required knowledge and records from the fact that mitigation occurred. The residential report also has its own current-condition and specific history questions; answer the actual question and provide a required written supplement if applicable information makes an earlier report inaccurate before closing. Do not say every old corrected condition must be reported forever, or that every past record can be discarded after a repair.

Official sources and scope
Reviewed October 29, 2026 using the identified primary sources. Current operative lead and AAI regulations are distinguished from general agency summaries and older program fact sheets. Use the Section 10 radon sale document for a covered sale and the separate Section 26 tenant package for a covered lease; the forms are not interchangeable. Earlier actual readings and their bounds are retained in the review record. No property, assessment, agency closure, insurance policy or private deadline is certified here.
