Property Disclosures topic guide

Land-use-control red flags

A buyer may love the building and still be unable to run the planned business, add the second unit, rebuild the garage, or divide the land. Exam questions reward the broker who recognizes that gap before promising an outcome.

Last updated: August 1, 2026

What does this exam area cover?

Short answer: Treat any mismatch among the current use, proposed use, zoning, permits, parcel layout, public maps, or private restrictions as a reason to verify. Public and private controls are separate. The broker identifies the signal, protects the client's investigation rights, and refers the legal, technical, or approval question without guaranteeing that a use is lawful or will be approved.

The national outline effective June 24, 2026 tests land-use-control red flags within Property Disclosures. Illinois municipalities and counties receive zoning authority by statute, but local ordinances supply parcel-level rules. This guide teaches issue recognition and referral, not a substitute for reading the controlling ordinance, recorded documents, permits, or professional opinions.

What is on the official outline?

Topic: Proposed-use mismatch
What to know: Home business, short-term rental, second dwelling, daycare, restaurant, retail, office, contractor yard, warehouse, assembly use, farm use, animals, parking demand, signage, outdoor storage, occupancy, noise, and hours
Best exam move: Write down the buyer's exact intended use and make approval a due-diligence question instead of assuming that a broad district label is enough.

Topic: Zoning district and permitted use
What to know: Municipal zoning, county zoning, map, district, permitted use, accessory use, prohibited use, use table, overlay, planned development, annexation, unincorporated area, jurisdiction, parcel identification number, and zoning letter
Best exam move: Verify both the controlling jurisdiction and the rules that apply to the specific parcel and use.

Topic: Special use, variance, and rezoning
What to know: Special use, conditional use, variance, hardship, standards, public hearing, notice, recommendation, board, corporate authority, rezoning, map amendment, conditions, expiration, appeal, neighboring property, and approval risk
Best exam move: Distinguish existing rights from discretionary relief that still requires an application, evidence, hearing, and decision.

Topic: Nonconforming use and structure
What to know: Lawful prior use, grandfathered claim, nonconforming lot, nonconforming structure, change of use, expansion, repair, casualty, abandonment, discontinuance, amortization, certificate, proof, zoning history, and loss of status
Best exam move: Ask whether the status is documented and whether the buyer's change, vacancy, expansion, or rebuilding plan would preserve it.

Topic: Dimensional controls
What to know: Setback, height, lot area, lot width, floor-area ratio, density, open space, lot coverage, building line, yard, frontage, parking ratio, loading, landscaping, buffer, fence, sign, and accessory structure
Best exam move: Compare the ordinance with a current survey and approved plans rather than estimating distances or coverage by sight.

Topic: Permits and occupancy records
What to know: Building permit, trade permit, zoning approval, plan review, inspection, final approval, certificate of occupancy, stop-work order, violation notice, open permit, expired permit, after-the-fact permit, unpermitted conversion, and municipal file
Best exam move: A finished improvement is not proof of lawful work. Obtain the relevant record and confirm whether the approval process was completed.

Topic: Subdivision and parcel creation
What to know: Division of land, Plat Act, subdivision plat, resubdivision, lot consolidation, parent tract, survey, monument, street dedication, utility way, public ground, drainage study, local approval, recordation, and buildable lot
Best exam move: Do not market a proposed split or extra lot as buildable until survey, subdivision, access, utility, zoning, and approval requirements are verified.

Topic: Floodplain, drainage, and stormwater
What to know: FEMA map, flood insurance rate map, special flood hazard area, base flood elevation, floodway, local floodplain ordinance, elevation certificate, fill, stormwater, detention, drainage easement, ponding, runoff, culvert, and map revision
Best exam move: Use the official map as a screening source and refer parcel, elevation, development, insurance, and lender questions to the proper specialists.

Topic: Wetlands and protected resources
What to know: Wetland indicator, hydrology, soil, vegetation, stream, waters of the United States, delineation, jurisdictional determination, dredged material, fill material, Section 404 permit, Corps review, buffer, habitat, and mitigation
Best exam move: A wet-looking area neither proves nor disproves jurisdiction. Development plans may require a professional delineation and agency review.

Topic: Private restrictions and title matters
What to know: Declaration, restrictive covenant, deed restriction, homeowners association, condominium instrument, architectural review, easement, building line, use restriction, rental limit, pet rule, maintenance obligation, amendment, expiration, waiver, and title exception
Best exam move: Check recorded and association controls even when public zoning allows the proposed use.

Topic: Broker communication and contract protection
What to know: Accurate advertisement, buyer use, seller statement, known violation, disclosure, document request, attorney review, zoning contingency, feasibility period, permit contingency, survey, title objection, professional referral, written verification, deadline, amendment, and termination
Best exam move: Convert the red flag into a documented investigation with a responsible source and a contract deadline.

Which distinctions produce the most mistakes?

Terms: Zoning vs. building code
Difference: Zoning controls land use, location, density, and dimensional relationships. Building codes regulate construction and safety standards.
Question cue: May it be used there versus how must it be built.

Terms: Variance vs. special use
Difference: A variance grants relief from a requirement in a specific case. A special use permits a use classified for discretionary approval under ordinance standards.
Question cue: Relief from a rule versus approval of a listed conditional use.

Terms: Nonconforming use vs. illegal use
Difference: A nonconforming use may have been lawful when established and later became inconsistent with changed rules. An illegal use lacked required legal authorization.
Question cue: Lawful before the change versus never lawfully approved.

Terms: Public control vs. private control
Difference: Zoning, building codes, and environmental permits arise from government authority. Covenants, declarations, and easements arise from private instruments.
Question cue: Municipal ordinance versus recorded declaration.

Terms: Permitted use vs. buildable project
Difference: A district may allow a use, while setbacks, access, utilities, parking, floodplain rules, wetlands, permits, or private controls still prevent the proposed project.
Question cue: Use category allowed versus complete project feasible.

Terms: Permit issued vs. permit closed
Difference: Issuance authorizes specified work subject to conditions. Closure or final approval indicates the required inspections and completion steps were accepted under that process.
Question cue: Permission to begin versus approved completion.

Terms: FEMA map review vs. elevation determination
Difference: A map identifies mapped flood-hazard context. A property-specific elevation or boundary conclusion may require an elevation certificate, survey, engineering, or official determination.
Question cue: Screening map versus parcel-specific technical evidence.

Terms: Wetland indicator vs. jurisdictional determination
Difference: Water, vegetation, or soil may signal a possible wetland. The appropriate technical and agency process determines delineation and federal jurisdiction.
Question cue: Reason to investigate versus regulatory conclusion.

Terms: Subdivision approval vs. zoning approval
Difference: Subdivision controls the legal division and platting of land. Zoning controls uses and development standards for resulting parcels.
Question cue: May the parcel be created versus how may it be used.

The CONTROL check for land-use questions

Clarify the intended use. Record what the client wants to operate, build, divide, rent, park, store, alter, or reconstruct.
Open the right records. Locate the zoning map, ordinance, survey, title commitment, permit file, occupancy record, approved plans, declaration, flood map, and available environmental information.
Name every control layer. Separate municipal or county zoning, subdivision, construction, fire, health, floodplain, environmental, and private restrictions.
Test current status. Ask whether the existing use and improvements were lawfully established, finally approved, and remain compliant.
Request qualified verification. Use the local authority, attorney, surveyor, engineer, architect, environmental professional, lender, insurer, or title professional for the conclusion within that role.
Observe the contract clock. Preserve attorney-review, feasibility, inspection, survey, title, financing, permit, zoning, and termination deadlines.
Leave approval uncertain until issued. An application, informal opinion, neighbor's experience, or seller's confidence is not the required government decision.

How do the rules work in scenarios?

The two-flat that records call a single-family home

Scenario: A listing describes two complete apartments. The assessor shows a single-family classification, and the seller cannot find permits for the lower kitchen or a second certificate of occupancy.

Physical layout and tax description do not establish zoning or occupancy approval.
The missing records are a warning that use, construction, safety, financing, appraisal, or insurance may require further review.

Answer: Market only facts that can be supported, disclose known adverse physical facts as required, and direct the parties to municipal, legal, lender, appraisal, and insurance review before treating the second unit as lawful income.

The business use is listed as special

Scenario: A buyer wants to convert a residence into a daycare. The local use table identifies that activity as a special use in the district, and no approval currently exists.

A special-use classification is not the same as present permission.
The process may require an application, notice, hearing, standards, conditions, and final action.

Answer: The buyer should investigate the approval process and protect the purchase with suitable legal and feasibility terms rather than relying on an agent's prediction.

The old cottage may not be rebuildable

Scenario: A lake cottage sits closer to the water and side line than current rules allow. The buyer plans to demolish it and build a larger home in the same footprint.

The current structure may be nonconforming, but demolition, expansion, casualty, or abandonment rules can change what survives.
Floodplain, shoreline, septic, access, and private controls may add separate limits.

Answer: Verify nonconforming status and all redevelopment rules with the governing bodies and qualified professionals before representing the plan as feasible.

A wet corner changes the development plan

Scenario: A buyer wants to place a driveway and workshop across the lowest part of a rural parcel. Standing water and wetland-type vegetation appear there in spring.

Appearance is enough to prompt investigation but not enough to decide jurisdiction.
Fill, drainage, access, floodplain, soil, septic, local permits, and Section 404 review may affect the plan.

Answer: The buyer should obtain environmental and engineering guidance and contact the responsible permitting authorities before ending the feasibility review.

What are the common exam traps?

Trap: Residential zoning allows every residential use.
Correction: Districts distinguish dwelling types and may separately regulate rentals, home occupations, density, parking, and accessory uses.

Trap: Grandfathered means the owner can expand or rebuild freely.
Correction: Local nonconforming-use rules control continuation, change, expansion, casualty, and abandonment.

Trap: A variance is guaranteed when a buyer needs one.
Correction: A variance requires the applicable process and findings, and approval remains uncertain until formally granted.

Trap: A permit proves every legal requirement was satisfied.
Correction: Confirm the permit's scope, conditions, inspections, final status, and separate approvals.

Trap: A tax record proves lawful use and square footage.
Correction: Assessment data serves taxation and does not replace zoning, permit, survey, appraisal, or occupancy evidence.

Trap: Zoning permission overrides a restrictive covenant.
Correction: Public permission and private restrictions operate separately, and the more restrictive result may control the planned use.

Trap: A parcel on a recorded plat must be buildable.
Correction: Creation of a lot does not guarantee current zoning, access, utility, septic, floodplain, wetland, or permit feasibility.

Trap: No visible water means no flood or wetland concern.
Correction: Flood hazards and wetlands cannot be ruled out by a single dry-weather visit.

Trap: The broker should interpret the ordinance and promise approval.
Correction: The broker can locate a concern and coordinate verification, but legal and technical conclusions belong to the responsible authority or professional.

Trap: The seller's long use proves it was lawful.
Correction: Duration alone does not prove permits, approval, or protected nonconforming status.

Can you answer these original practice questions?

These questions are original study items aligned to the published outline. They are not copied, recalled, or predicted PSI questions.

1. A buyer wants to operate a use classified by the local ordinance as a special use. Which statement is most accurate?

The use is automatically permitted
The buyer must follow the required approval process and should not assume approval
A home inspection grants approval
The seller may waive zoning

Show answer and explanation

Answer: B

Illinois municipal law allows ordinances to classify special uses that require a hearing and evidence that ordinance standards are met.

2. A garage was lawful before a zoning amendment but does not meet today's side setback. What should be verified first?

Whether the paint color is popular
Its documented nonconforming status and the local rules for alteration, rebuilding, and abandonment
Only the property's list price
Whether the neighbor likes it

Show answer and explanation

Answer: B

A prior lawful condition may qualify for nonconforming treatment, but the local ordinance controls what can continue or change.

3. Which item is a private land-use control?

Municipal zoning ordinance
County building code
Recorded restrictive covenant
Federal wetlands permit

Show answer and explanation

Answer: C

A recorded restrictive covenant arises from a private instrument. The other answers are public controls.

4. A buyer sees standing water and wetland-type vegetation where a building is planned. What is the best broker response?

Guarantee that no permit is needed
Guarantee that construction is prohibited
Recommend timely environmental and agency verification before the feasibility deadline
Ignore the condition because the visit occurred in spring

Show answer and explanation

Answer: C

The observations are red flags, but delineation, jurisdiction, and permit consequences require qualified technical and agency review.

5. A local zoning map allows retail use, but the recorded declaration prohibits retail activity. Which conclusion is best?

Zoning automatically cancels the declaration
The private restriction must be reviewed separately even though public zoning allows the use
The broker can erase the restriction
The declaration matters only to the assessor

Show answer and explanation

Answer: B

Public zoning and private title restrictions are separate control layers. Permission under one does not eliminate the other.

Questions students ask about Land-Use-Control Red Flags

What is a land-use-control red flag?

It is a fact suggesting that a property's present or intended use may be limited, unlawful, conditional, or expensive to continue. Examples include an unpermitted addition, a use that conflicts with current zoning, a structure inside a setback, an undersized lot, a private restriction, flood-hazard mapping, wetland indicators, or a proposed use that needs a variance or special-use approval.

Does zoning prove that a buyer can use property as planned?

No. A zoning classification is only a starting point. The proposed use may also depend on dimensional rules, parking, access, occupancy, building codes, permits, utilities, subdivision approval, private covenants, environmental restrictions, and facts specific to the parcel. Buyers should verify the exact use with the controlling authorities and appropriate professionals.

What is a legal nonconforming use?

It is generally a use that lawfully existed before a later zoning change made that use inconsistent with current rules. Local ordinances determine whether it may continue, expand, change, be rebuilt, or resume after abandonment or destruction. A broker should verify status instead of treating age or long use as proof.

How is a variance different from a special use?

A variance typically provides relief from a zoning requirement for a particular property, often a dimensional rule. A special use allows a use classified by ordinance as appropriate only after the required review and findings. Neither is automatic, and the local ordinance and decision control.

Does a building permit prove zoning compliance?

Not necessarily. Permitting, zoning, occupancy, subdivision, health, fire, and environmental approvals can answer different questions. A permit also may cover only stated work. Verify the record, final inspection, certificate, approved plans, conditions, and any separate approvals relevant to the client's use.

What can reveal a setback or lot-coverage problem?

A current survey, zoning ordinance, approved site plan, permit file, and municipal or county verification may reveal it. Garages, decks, pools, sheds, fences, additions, and widened driveways are common signals. A broker should not estimate compliance from appearance alone.

Why are flood maps and wetlands land-use concerns?

They may affect development, fill, drainage, insurance, financing, permits, elevation requirements, and the cost or feasibility of a project. A map or wet area is a screening signal, not a complete legal determination. FEMA, local floodplain officials, environmental professionals, and the proper permitting agencies supply the controlling evidence.

Can private covenants be more restrictive than zoning?

Yes. Zoning is a public land-use control, while a declaration, covenant, easement, or association rule is a private control. A use may be allowed by local zoning but prohibited by a recorded covenant. Both layers must be reviewed separately.

What should a broker do when a buyer proposes a risky use?

State the concern accurately, avoid guaranteeing approval, document the buyer's intended use, protect due-diligence and contract deadlines, and refer the buyer to the local authority, attorney, surveyor, engineer, architect, environmental professional, lender, insurer, or other qualified source as appropriate.

Are these actual PSI exam questions?

No. They are original practice questions based on the public Property Disclosures outline effective June 24, 2026.
