Illinois flooding disclosure for landlords

Illinois flood disclosure is not just a basement-apartment rule. Covered rentals have a mapped-zone and known-history layer. Garden, basement and first-floor units add a property-wide, ten-year inquiry. Keep those duties separate from the conditions for ending a lease or claiming damages.

Last reviewed:

The short answer

Under 765 ILCS 705/25, covered landlords disclose FEMA Special Flood Hazard Area information and actually known flooding of the rental property or associated parking areas, including frequency. For a garden, basement or first-floor unit, the added inquiry covers flooding of the unit or any part of its containing real property during the last ten years. Disclose in writing before signing, include the statement in the written lease or renewal, and obtain both signatures. The two tenant termination paths have different 30-day triggers; a qualifying advance-rent-and-fee refund is due within 15 days after the tenant gives notice.

The PSI outline effective June 24, 2026 lists Flooding for Landlords in Illinois IV.E.5. Disclosures as a whole accounts for 10 of the 40 scored state broker questions, not a separate quota for this page. The current statutory source note identifies Public Act 103-754, effective January 1, 2025, and Public Act 104-417, effective August 15, 2025. Use the operative text and its exemptions rather than attributing every duty to the later amendment.

Check scope, facts, writing and remedy

  1. Start with coverage. Identify the actual lease and the section's farm, concession and IDNR ownership-or-management exemptions. Do not import an owner-occupied exemption from a different law.
  2. Classify the unit. Garden, basement and first-floor units fall within the statutory lower-level definition. The additional history inquiry reaches the containing property, not only the dwelling interior.
  3. Separate the facts. Mapped-zone information, actual flood history, the source of the water and frequency answer different questions. A dry unit or an unmapped location does not prove no relevant flooding.
  4. Read the wording carefully. Subsection (b) states its actual-knowledge history duty; subsection (c) and the statutory form contain ten-year language. Do not insert a ten-year limitation into every sentence of subsection (b).
  5. Complete the required sequence. Give the written disclosure before signing; include it in the written lease or renewal and have both parties sign. Substantially similar statutory content matters, not one brand of form.
  6. Choose the remedy by its conditions. Separate awareness of a subsection (b) failure from a later qualifying flood. A 15-day return period runs from the tenant giving notice, not move-out or the date the tenancy ends.
  7. Check time computation, how notice is given and any controlling provision. The statutory numbers are not a private deadline calculation or permission to assume mailing alone is sufficient.

The distinctions that matter

Illinois landlord flooding disclosures under 765 ILCS 705/25: key distinctions
DistinctionHow it worksWhat to notice
All rentals vs. lower-level rentalsSubject to the section's exemptions, subsection (b) applies beyond lower-level units. Subsection (c) adds its ten-year unit-or-containing-property inquiry for garden, basement and first-floor rentals.Universal layer plus location-specific layer.
Flood zone vs. flood historySpecial Flood Hazard Area status comes from FEMA mapping. Flood history records events that actually occurred. A property can have one fact without the other.Mapped probability versus experienced event.
Unit flooding vs. property floodingThe lower-level rule reaches flooding of the unit or any portion of the real property containing it. A dry apartment does not erase a flooded lot or common area.Inside dwelling versus anywhere on parcel.
Rental property vs. parking areaSubsection (b) expressly makes known flooding of the rental property or any portion of the associated parking areas relevant.Dwelling and vehicle-access areas.
Prior written disclosure vs. lease inclusionThe disclosure must be in writing before signing and included in the written lease or renewal with both signatures. A later email does not retroactively establish the required sequence.Advance notice plus signed contract record.
Initial lease vs. renewal leaseThe current disclosure language belongs in both the written lease and written renewal lease. A prior tenant's signature is not the new tenant's acknowledgment.Current parties and current agreement.
30 days after awareness vs. 30 days after floodThe mapped-zone path requires a subsection (b) failure and subsequent awareness that the property is in the SFHA; its 30-day period runs from awareness of the failure. The later-flood path uses the qualifying flood as its trigger.Two remedies, two trigger dates.
Termination refund vs. property damagesUnder the stated remedy, all rent and fees paid in advance are returned within 15 days after the tenant gives notice. A personal-property damages action is separate from an automatic award or a guarantee of every economic loss.Money paid ahead versus loss caused by water.
Flood vs. recurring leakageUse Section 25's inundation definition and its listed overflow, unusual and rapid runoff or surface-water accumulation, or rainfall causes. A plumbing leak is not automatically that statutory flood; a sewer-backup label does not resolve the actual cause either.Inundation event versus system leak.
Landlord flood form vs. seller reportThe landlord form serves tenants before a lease or renewal. The seller report serves prospective buyers before a covered sales contract and contains different flood questions.Rental transaction versus sale transaction.
Disclosure duty vs. insurance coverageSection 25 requires information and creates specified remedies. It does not interpret a tenant's renter's or flood policy or promise payment for a future loss.Transaction notice versus risk-transfer contract.
Disclosure compliance vs. legal occupancyA landlord may complete the flood form and still violate a municipal prohibition against renting that lower-level unit. The state statute does not grant occupancy permission.Truthful notice does not legalize use.
Not aware and certified outside the flood areaThe statutory form asks about the landlord's awareness. A lack of awareness is not a professional certification that the property lies outside the mapped area or has never flooded.Preserve what the statement actually asserts.
A 30-day period and 30 business daysIllinois' general statutory computation rule excludes the first day, includes the last, and excludes a Saturday, Sunday or statutory holiday at the end, including succeeding excluded days. Apply its construction context and any controlling provision.Intermediate weekends are not all removed from a calendar count. Check the final day and actual notice requirements.

Work through the facts

A fifth-floor apartment shares a flooded lot

A landlord leases a nonexempt fifth-floor unit in a building outside the FEMA Special Flood Hazard Area. The landlord actually knows that the parking lot flooded twice from heavy rainfall.

  1. The unit is not lower-level, so the additional subsection (c) classification does not apply.
  2. Subsection (b) still applies to every rental and expressly includes known parking-area flooding and its frequency.

Answer: Disclose the mapped status and two known parking-lot floods before signing and include the signed statement in the lease.

A first-floor unit stayed dry

A first-floor apartment never took water, but the building's basement and driveway flooded three times during the last 10 years.

  1. First floor is a lower-level unit.
  2. Subsection (c) reaches flooding of the unit or any portion of the real property, so a dry apartment does not erase the basement and driveway history.

Answer: Disclose the three events and frequency in the lower-level-unit process.

The flood email follows the signature

The parties sign a renewal at noon. The property manager emails the flood statement at 2 p.m., and the renewal contains no disclosure language.

  1. Section 25 requires the writing before signing.
  2. It also requires inclusion in the written renewal and both parties' signatures.

Answer: The post-signing email misses both the timing and signed-agreement requirements.

Tenant discovers the mapped zone

A landlord omitted subsection (b) in a nonexempt rental. Six months later, the tenant learns that the rental is in the FEMA Special Flood Hazard Area and becomes aware of the landlord's failure to comply. No flood is needed for the question about this stated remedy.

  1. The statute provides a termination path when the tenant becomes aware of the landlord's failure concerning mapped status.
  2. The tenant must give written notice no later than the 30th day after that awareness, subject to the applicable time-computation and notice requirements; do not assume mailing alone proves notice was given.

Answer: Use the awareness-based 30-day notice path, not a clock measured from lease signing.

A flood blocks the only entrance

After a required flooding history was omitted, a storm flood blocks the tenant's only access to the unit but does not damage the tenant's furniture.

  1. The later-flood remedy is not limited to damaged personal property.
  2. A flood that affects access is one of the listed consequences, provided the other statutory conditions are met.

Answer: Analyze the 30-day post-flood termination path even without furniture damage.

The city prohibits basement rentals

A landlord completes the flood statement for a basement unit that the municipality does not permit to be rented.

  1. Disclosure may communicate flood facts accurately.
  2. Section 25 expressly refuses to authorize a lower-level rental prohibited by the municipality.

Answer: The completed form does not make the basement unit legal to rent.

Start the mapped-zone clock at the specified awareness

Assume all conditions for the mapped-zone remedy are met. A tenant becomes aware of the subsection (b) failure on September 2, 2026 and gives valid written termination notice on September 10. For this exercise, the general statutory time rule governs, no other provision changes it, and the calculated final weekdays are not statutory holidays.

  1. Exclude September 2. The 30 thday is October 2, 2026, a Friday; this is the stated notice deadline for that remedy.
  2. The actual notice was given earlier, on September 10. Exclude that trigger day; its 15 thday is September 25, a Friday.
  3. The refund clock follows the actual notice, not October 2, a later move-out or the effective termination date.

Answer: The stated notice deadline is October 2; advance rent and fees must be returned by September 25 under the stipulated conditions.

Use the flood trigger for the separate route

Assume a nonexempt landlord failed subsection (b) or (c), and flooding on September 1, 2026 affects tenant access. All other remedy conditions are met. The tenant gives valid written notice on September 10. The general statutory time rule governs; no other rule or final-day holiday changes this exercise.

  1. For this route, the 30 thday after the September 1 flood is October 1, 2026, a Thursday.
  2. Notice was actually given on September 10, so the 15 thday refund date is September 25, a Friday.
  3. An earlier flood-history discovery date is not substituted for the flood trigger in this second route.

Answer: Use October 1 for the stated flood-based notice deadline and September 25 for the notice-based return deadline.

Separate the return from a damages claim

A tenant has validly invoked a Section 25 remedy in an exercise. The landlord holds $2,400 rent and $150 fees paid in advance, both stipulated to fall within the statutory return. The tenant also alleges $2,000 in personal-property loss. Exclude security-deposit treatment and all other adjustments.

  1. The stated advance-payment return is $2,400 + $150 = $2,550.
  2. The alleged $2,000 loss is not automatically added to that mandatory subtotal merely because an action may be brought.
  3. The property-loss action needs its actual conditions and proof; this arithmetic approves neither liability nor an award.

Answer: The stated advance-payment subtotal is $2,550, with the alleged property damages treated separately.

Look past the label attached to the water

In one exercise, unusually rapid rainfall runoff inundates part of a rental property. In another, the only established fact is that a tenant called an incident a sewer backup; the water source and cause are not established.

  1. The first set of stated facts supplies inundation from a listed cause for the definition question.
  2. The second label alone does not establish or exclude the statute's listed cause. Determine the facts rather than assuming every sewer backup is exempt or every water loss is a statutory flood.
  3. Whether disclosure was omitted, a remedy exists or insurance responds requires additional facts.

Answer: Classify the event from the statutory definition and established cause, not a shorthand label or an insurance-policy definition.

A weekend at the end is different from thirty business days

Assume the general Illinois statutory computation rule applies, with no controlling exception. After excluding the trigger day, the 30 thday of this hypothetical period is Saturday. The next day is Sunday and the following Monday is not a statutory holiday. No actual tenant date or delivery method is being approved.

  1. The ending Saturday is excluded under the stated rule.
  2. The succeeding Sunday is also excluded.
  3. Monday is included under the stated no-holiday assumption. Intermediate weekends were not all removed from the count.

Answer: The stated final day is Monday; the rule does not turn the whole period into thirty business days.

Owned or managed means either stated connection

Compare three hypothetical leases. A is a rental property privately owned but managed by IDNR. B is an owner-occupied two-flat rental with no farm, concession or IDNR ownership or management facts. C is stipulated to be a farm lease. Assume no other fact changes those classifications.

  1. A meets the stated IDNR-management exemption even though IDNR does not own it.
  2. B is not exempt solely because the owner occupies the two-flat; Section 25 does not list that general exception.
  3. C meets the express farm-lease exemption. None of these classifications legalizes a locally prohibited lower-level rental.

Answer: A and C fit the stated express exemptions; owner occupancy alone does not exempt B.

Mistakes to avoid

  • Only basement apartments need the disclosure Covered upper-floor rentals still have subsection (b) duties; first-floor units also meet the lower-level definition.
  • A dry apartment means the property history is irrelevant The lower-level inquiry reaches any part of the containing real property, and known parking flooding is expressly relevant under (b).
  • The same ten-year limit appears in every history sentence Subsection (c) and the form use ten years; subsection (b) does not state that same cutoff. Do not silently rewrite its actual-knowledge duty.
  • Not aware means the landlord has certified no flood risk Awareness, an actual map determination and a guarantee of safety are different statements.
  • An oral warning or unsigned later email completes compliance The statute requires the writing before signing, signed lease-or-renewal inclusion and substantially similar content.
  • A landlord has 15 days after move-out to make the Section 25 refund The stated return clock runs from the tenant giving termination notice under the applicable remedy.
  • Any later flood automatically ends the lease The later-flood route requires the disclosure failure and specified harm to property, habitability or access, followed by qualifying notice.
  • Access problems guarantee payment for undamaged belongings Access can satisfy the termination consequence; a property-loss action needs an actual relevant loss and its legal conditions.
  • An owner-occupied two-flat is automatically exempt That is not a listed Section 25 exemption. Do not transplant another law's building-size exception.
  • Flood disclosure guarantees contents insurance The statute's warning and the actual insurance policy have different functions.
  • A tenant must wait for a flood before the mapped-zone remedy can apply The first route has its own subsection (b) failure and later-awareness conditions; it does not require a later flood.
  • The August 2025 amendment alone introduced the every-landlord wording The earlier enactment already used that wording. Use the current section without inventing a change in scope.
  • Thirty days always means thirty business days Apply the proper computation rule, including its last-day treatment and any controlling exception.
  • A completed form legalizes a prohibited basement rental Section 25 expressly preserves the municipal prohibition on renting, leasing or subleasing such lower-level units.

Check your understanding

These are original teaching questions, not recalled or predicted PSI questions. Answer first, then explain why the other choices fail.

1. Which unit is a lower-level unit under 765 ILCS 705/25?

  1. Garden and basement units only
  2. Every unit in a building with a basement
  3. A garden, basement, or first-floor unit
  4. Only dwelling space below street grade
Show answer and explanation

Answer: C. A garden, basement, or first-floor unit

The statutory definition expressly lists garden-level, basement-level, and first-floor-level units.

2. A fifth-floor rental's parking area flooded twice. Which statement is correct?

  1. Disclosure is required only if the fifth-floor dwelling itself flooded
  2. Only the extra lower-level history rule can ever cover parking
  3. A location outside the SFHA automatically removes every history duty
  4. The every-rental rule can require disclosure of known parking-area flooding and frequency
Show answer and explanation

Answer: D. The every-rental rule can require disclosure of known parking-area flooding and frequency

Subsection (b) applies to every landlord and specifically reaches known flooding of associated parking areas.

3. Where must the Illinois landlord flood disclosure appear?

  1. In writing before signing, with lease inclusion and only the landlord's signature
  2. Only in a separate oral warning acknowledged by the tenant
  3. Only in the written lease, with no requirement to disclose before signing
  4. In writing before signing and in the written lease or renewal signed by both parties
Show answer and explanation

Answer: D. In writing before signing and in the written lease or renewal signed by both parties

The statute combines pre-signing written notice with signed lease or renewal inclusion.

4. A landlord omitted the required history, and a later flood blocks tenant access. When must a qualifying termination notice be given?

  1. No later than 30 days after an earlier unrelated history discovery
  2. No later than 30 days after the flood
  3. No later than 30 days after lease signing, regardless of the flood date
  4. No later than 15 days after the landlord receives the next rent payment
Show answer and explanation

Answer: B. No later than 30 days after the flood

Access is a listed consequence, and the later-flood termination notice is due no later than the 30th day after the flood.

5. Which lease is expressly exempt from Section 25?

  1. A farm lease
  2. An otherwise covered fifth-floor apartment lease
  3. An otherwise covered owner-occupied two-flat lease
  4. An otherwise covered single-family rental lease
Show answer and explanation

Answer: A. A farm lease

The statute lists farm leases, concession leases, and qualifying IDNR properties as exemptions.

6. A first-floor unit stayed dry, but another portion of its containing property flooded during the last ten years. Does that fact fall within the additional subsection (c) inquiry?

  1. No, because only water inside the unit counts
  2. No, because first-floor units are excluded
  3. Yes, but only if the property is also in the SFHA
  4. Yes; the inquiry reaches the unit or any portion of the containing real property
Show answer and explanation

Answer: D. Yes; the inquiry reaches the unit or any portion of the containing real property

The statutory lower-level definition includes first floor, and the additional inquiry is not confined to the dwelling interior or mapped flood area.

7. Which statement most accurately describes the form of the written disclosure?

  1. The landlord can replace it with an oral risk warning
  2. Its content must look substantially similar to the statutory disclosure, with the required timing and signatures
  3. Only a seller report can satisfy the rental rule
  4. Only one trade association's branded PDF is legally allowed
Show answer and explanation

Answer: B. Its content must look substantially similar to the statutory disclosure, with the required timing and signatures

Section 25 (d) uses substantially similar statutory content. That does not excuse pre-signing writing, lease-or-renewal inclusion or both signatures.

8. Under the stated Section 25 termination remedy, what starts the 15-day advance-rent-and-fee return period?

  1. The date the tenant gives the required notice
  2. The date the tenant moves out
  3. The next scheduled rent day
  4. The date a later court action is filed
Show answer and explanation

Answer: A. The date the tenant gives the required notice

The statute measures this return period from when the tenant gave notice, not from a different event or the 15 thday before a flood.

9. Can the mapped-zone termination route apply without a later flood?

  1. No, unless the dwelling is below grade
  2. No, every Section 25 remedy requires damaged furniture
  3. Yes, if the subsection (b) failure and subsequent awareness conditions are met and qualifying notice is given
  4. Yes, for every unrelated lease complaint
Show answer and explanation

Answer: C. Yes, if the subsection (b) failure and subsequent awareness conditions are met and qualifying notice is given

The first remedy has its own failure and SFHA-awareness conditions. A later flood with specified consequences is the separate route; neither is an automatic remedy for any complaint.

10. Does living outside the mapped SFHA alone eliminate the relevant flood-history duties?

  1. No; mapped status and relevant actual history are different facts
  2. Yes, if no mortgage lender demanded insurance
  3. No, because every property is legally inside the SFHA
  4. Yes, because floods cannot occur outside it
Show answer and explanation

Answer: A. No; mapped status and relevant actual history are different facts

The statutory form warns about flooding outside the mapped area, and the history provisions have their own coverage and conditions.

11. Which rental is within an express Section 25 exemption solely under the facts stated?

  1. Every first-floor apartment
  2. A privately managed owner-occupied two-flat
  3. A rental property managed by the Illinois Department of Natural Resources
  4. Every rental whose tenant has insurance
Show answer and explanation

Answer: C. A rental property managed by the Illinois Department of Natural Resources

The section exempts rental properties owned OR managed by IDNR, as well as farm and concession leases. An owner-occupied building is not automatically exempt under this section.

12. A landlord accurately completes the form for a lower-level unit that a municipality prohibits from being rented. What follows?

  1. The tenant's insurance legalizes the unit
  2. The form grants an occupancy permit
  3. Both signatures waive the municipality's rule
  4. The disclosure does not authorize the prohibited renting, leasing or subleasing
Show answer and explanation

Answer: D. The disclosure does not authorize the prohibited renting, leasing or subleasing

Section 25 (f) expressly preserves that municipal limit. Truthful disclosure and legal occupancy are separate requirements.

13. A household has an ordinary renters policy. Does the landlord flood statement itself establish coverage for the household's flood-damaged belongings?

  1. Yes, for every water event without exclusions
  2. Yes, because a signed disclosure is an insurance binder
  3. No; actual insurance coverage and eligibility require their own review
  4. No insurance policy can ever cover tenant contents
Show answer and explanation

Answer: C. No; actual insurance coverage and eligibility require their own review

Most renters policies do not typically include flood coverage. Separate NFIP or private coverage can have actual eligibility, terms, limits and exclusions; a disclosure is not a policy.

14. Assume all statutory remedy and notice conditions are met, and $2,400 rent plus $150 fees were paid in advance and fall within the specified return. Excluding other adjustments, what subtotal is returned?

  1. $150
  2. $2,550
  3. $2,000
  4. $4,550
Show answer and explanation

Answer: B. $2,550

Add the two stipulated advance payments: $2,400 +$150=$2,550. An alleged separate personal-property loss is not automatically an additional award.

15. A tenant calls an incident a sewer backup, but its water source and cause are not established. Which conclusion is supported by that label alone?

  1. Every sewer backup satisfies the statutory flood definition
  2. The tenant automatically wins a personal-property award
  3. Neither conclusion; establish the listed cause and inundation facts
  4. Every sewer backup is exempt from Section 25
Show answer and explanation

Answer: C. Neither conclusion; establish the listed cause and inundation facts

Apply the actual statutory definition and established facts. A label alone does not resolve flooding, disclosure failure, remedies or insurance coverage.

16. Does the term 100-year flood mean the flood must occur exactly once in each 100-year period?

  1. Yes, with no chance of another flood before then
  2. Yes, unless the property is rented
  3. Yes, because past floods reset the schedule
  4. No; it describes an annual probability concept, not a fixed appointment
Show answer and explanation

Answer: D. No; it describes an annual probability concept, not a fixed appointment

The IDNR overview describes a 1% chance in any given year. That general concept is not a current parcel determination or a guarantee that a particular dwelling will or will not flood.

17. Which comparison accurately follows Section 25's actual wording?

  1. Every sentence in subsection (b) expressly limits history to ten years
  2. Subsection (c) and the form include ten-year language; subsection (b) itself does not state that same cutoff
  3. The form contains no history question
  4. The lower-level inquiry is restricted to the dwelling interior
Show answer and explanation

Answer: B. Subsection (c) and the form include ten-year language; subsection (b) itself does not state that same cutoff

Read the subsection and form together without silently inserting a missing cutoff or treating an older known event as automatically concealable. A particular older-history file needs its own qualified review.

18. The landlord checks not aware on the statutory SFHA statement. What does that statement alone establish?

  1. An automatic exemption from all other required disclosures
  2. A professional certification that the property is outside the SFHA
  3. The stated lack of awareness, not a guarantee of no mapped risk or flooding
  4. A guarantee that no flood has ever occurred
Show answer and explanation

Answer: C. The stated lack of awareness, not a guarantee of no mapped risk or flooding

Preserve the meaning of the awareness statement. It does not replace reliable map information, actual known history, other required content or the conditions for a remedy.

19. Assume Illinois' general statutory computation rule governs without a controlling exception. The 30 thday falls on Saturday, and the succeeding Monday is not a statutory holiday. Which final day results?

  1. Monday
  2. Thirty business days after the trigger in every case
  3. Sunday
  4. Saturday, regardless of the statute
Show answer and explanation

Answer: A. Monday

The rule excludes the last Saturday and succeeding Sunday. Under the stated no-holiday and no-other-rule assumptions, Monday is included. This does not approve a private deadline or notice-delivery method.

20. After a qualifying nondisclosure and flood, only access is affected and no personal property is lost or damaged. Which conclusion follows from those facts alone?

  1. Access can be a listed termination consequence, but a personal-property award is not established
  2. The tenant cannot use the termination route because furniture stayed dry
  3. Every insurance policy must pay contents damages
  4. The tenant automatically receives every alleged financial loss
Show answer and explanation

Answer: A. Access can be a listed termination consequence, but a personal-property award is not established

The statute separates the specified termination consequences from an action to recover property actually lost or damaged by flooding. Conditions, notice, proof and actual remedies remain necessary.

Common questions

What must an Illinois landlord disclose about flooding?

For covered rentals, subsection (b) addresses FEMA Special Flood Hazard Area information and the landlord's actual knowledge of flooding of the rental property or associated parking areas, including frequency. A lower-level rental adds subsection (c)'s inquiry about flooding of the unit or any containing real property during the last ten years. Follow the pre-signing writing, lease-or-renewal inclusion, both-signature and substantially-similar-form requirements. Apply the section's exemptions before assuming coverage.

Does lower-level include a first-floor apartment?

Yes. The definition expressly includes garden-level, basement-level and first-floor-level units. Do not replace it with only below street grade or only a windowless basement. A higher-floor unit can still fall under subsection (b); the additional subsection (c) classification is a separate question.

Does not aware mean the property is outside the floodplain?

No. The statutory form asks about the landlord's awareness; that is different from a professional determination of map location. A lack of awareness is not a guarantee that the property has no flood risk or history. Use relevant records and reliable map information without overstating what they establish. The independently cited IDNR overview identifies September 2024 data, not a new parcel-specific determination in October 2026.

Does the ten-year limit apply to every history sentence?

Read each provision. Subsection (c) expressly covers the last ten years, and the statutory form includes ten-year history language. Subsection (b) itself states an actual-knowledge duty for rental-property or parking flooding and frequency without stating that same time cutoff. Do not silently add one to every duty or assume an older known event may be concealed. A private question about reconciling form wording and particular older records needs its own qualified review.

Do parking floods matter when the apartment stayed dry?

Yes, where the relevant duty applies. Subsection (b) expressly includes actually known flooding of any portion of the parking areas of the real property containing the rental. For lower-level units, subsection (c) also reaches any portion of the containing real property within its stated ten-year period. Keep the event location, actual knowledge and frequency clear rather than treating a dry dwelling as the whole answer.

When must the statement be given, and who signs?

The statute requires clear written disclosure before lease signing. The disclosure also belongs in the written lease or written renewal and must be signed by both parties. A hallway warning is not the required writing, and a later unsigned email does not prove the full sequence was satisfied. This lesson does not approve a notice-delivery method or a private lease form.

Can a tenant terminate without waiting for a flood?

The mapped-zone route can apply if the landlord failed subsection (b) and the tenant subsequently becomes aware that the property is in the SFHA. The tenant must give written termination notice no later than the 30 thday after awareness of the landlord's subsection (b) failure. This is not simply 30 days after lease signing, any unrelated discovery or a storm. The actual conditions, notice and time-computation requirements still matter.

What if flooding later affects access but no belongings were damaged?

The separate later-flood route requires failure of subsection (b) or (c), followed by flooding that damages personal property, affects habitability OR affects access. Access alone can supply that listed consequence, subject to the other conditions. The termination notice period uses 30 days after the flood. A right to bring a personal-property-loss action does not automatically award damages for belongings that were not lost or damaged.

When must advance rent and fees be returned?

Under the specified termination remedies, the landlord must return all rent and fees paid in advance no later than the 15 thday after the tenant gave notice. Do not move that trigger to move-out, the effective end of the lease or a later court filing. This rule is not a complete security-deposit analysis or an automatic award of every alleged expense. Actual amounts, notice validity and applicable computation rules still require their own review.

Are the 30-day and 15-day periods business days?

Do not replace them with 30 or 15 business days. Illinois' general statutory computation rule excludes the first day and includes the last, but excludes a last day that is Saturday, Sunday or a statutory holiday, including succeeding excluded days. That rule has its statutory-construction context, and a controlling provision can matter. Intermediate weekends are not all removed. Establish the actual trigger and how notice is given before calculating a private deadline.

Must I buy or use a particular branded flood disclosure form?

Section 25 (d) calls for a writing that looks substantially similar to its statutory disclosure. The required substance includes the awareness statements, stated history and frequency, risk warnings, insurance information and both signatures. A different layout does not excuse missing substance, and the landlord statement is not the residential seller report. The official statute is the reference; no completed ready-to-sign form is supplied here.

Does a flood disclosure mean the tenant has insurance?

No. The statutory warning and Illinois Department of Insurance guidance explain that most ordinary homeowners and renters policies do not typically include flood coverage. Separate NFIP or private flood coverage can have eligibility, limits, exclusions and other conditions. Read the actual policy and endorsements. A signed disclosure is not a binder, a coverage decision or proof that every item in a lower-level unit is insured.

Is an owner-occupied two-flat exempt, and does the form legalize a basement rental?

Section 25 lists farm leases, concession leases and rental properties owned OR managed by IDNR. It does not list a general exemption solely because an owner lives in a two-flat. Do not borrow a building-size or occupancy exception from another law. The section also expressly says it does not authorize lower-level renting, leasing or subleasing that the municipality prohibits. A particular lease's classification and local rules need their own review.

What practice score proves readiness for this topic?

No validated readiness cutoff or pass probability is established for this original set. Identify the applicable subsection, required facts, writing and signatures, remedy trigger and notice deadline. Explain why the nearest wrong answer changes the result, then try a changed scenario later. These are original exercises based on the public outline; the whole state Disclosures allocation is not a prediction of the number of landlord-flood questions.

Does every sewer backup count as flooding under Section 25?

The label alone is not enough. Section 25 defines inundation caused by its listed overflow, unusual and rapid runoff or surface-water accumulation, or rainfall events. Establish the actual cause and extent. Do not assume every sewer backup is excluded merely because it came through a drain, or that every plumbing incident qualifies merely because someone called it a flood. Insurance can also use its own definitions. A particular incident requires its own factual and legal review.

Can the seller disclosure report replace the landlord flood statement?

No. The residential seller report serves a covered sale and has its own definitions, exemptions, questions, delivery and remedy rules. Section 25 serves its covered rental or lease transaction. A sale report's flooding or recurring-leakage answers do not by themselves satisfy rental timing, history, statutory content and both-signature requirements. Likewise, do not transfer the rental 30-day and 15-day clocks to a sale.

What should a broker or property manager distinguish from the landlord duty?

The landlord's Section 25 obligation and a licensee's own conduct duties are separate. Illinois requires honest treatment of customers and bars negligent or knowing false information. The specific latent-physical-fact paragraph in Section 15-25 uses a seller-client and prospective-buyer-customer relationship; do not silently rewrite it as the exact rule for every rental. Keep actual knowledge, source records, required writing and signatures clear, and avoid presenting an uncertain map location, insurance outcome or tenant remedy as certified.

What changed in 2025, and does Section 25 require a flood policy purchase?

The current source note identifies the January 1, 2025 enactment and August 15, 2025 amendment. The original enactment already used every-landlord wording in subsection (b), so do not describe that reach as created only by the later amendment. Read the current operative section and its exemptions. Its insurance warning is not an automatic purchase mandate or a guarantee of tenant-contents coverage. A proposed bill, another law, a lease term and an actual policy must be evaluated separately; a proposal is not current law.

Official sources and scope

Reviewed October 28, 2026 against the identified current Illinois provisions and recorded primary readings. The current section, including both paragraphs labelled (e), controls this lesson. Direct ILGA requests had upstream errors; the complete official indexed section was read, with earlier actual readings explicitly recorded. The independently read IDNR overview uses September 2024 map data; it is not a current parcel determination. No private lease, policy, notice, deadline or claim has been approved, completed or sent.
