Illinois rental flood exam guide

Illinois flooding disclosure for landlords

The current rule uses two flood checks. Every rental needs the mapped-zone and known-history disclosure required by subsection (b). A garden, basement, or first-floor unit adds subsection (c), which asks whether the unit or any part of the property flooded in the last 10 years. Put the answer in writing before signing, repeat it in the lease or renewal, and collect both signatures.

Last updated: August 1, 2026

What does current Illinois authority require?

Short answer: Under current 765 ILCS 705/25, every Illinois landlord makes a written pre-signing disclosure about FEMA Special Flood Hazard Area status and known flooding of the rental property or parking areas, including frequency. A landlord leasing a garden, basement, or first-floor unit also discloses whether the unit or any portion of the real property flooded in the last 10 years and how often. The disclosure appears in the written lease or renewal and is signed by both parties. A qualifying omission can support 30-day tenant termination windows, a 15-day refund deadline, and personal-property damages when a later flood causes the specified harm.

This guide applies Section 25 of the Illinois Landlord and Tenant Act as amended by Public Act 104-417, effective August 15, 2025, and current through August 1, 2026. It is exam preparation, not flood-zone certification, insurance advice, lease drafting, or legal advice about a tenant remedy.

Where is this tested on the Illinois outline?

Topic
Current law and scope
What to know
765 ILCS 705/25, Public Act 103-754, Public Act 104-417, effective January 1 2025, effective August 15 2025, every landlord, each tenant, rental property, lease, renewal lease, statewide rule, and current exam
Best exam move
Use the amended rule that reaches every rental rather than an older summary limited to lower-level units.
Topic
Statutory flooding definition
What to know
General inundation, temporary inundation, partial inundation, complete inundation, dwelling, property, overflow, inland water, tidal water, unusual accumulation, rapid accumulation, runoff, surface water, established source, river, stream, drainage ditch, and rainfall
Best exam move
Match the event to the statutory flood definition instead of limiting the term to river overflow.
Topic
Lower-level unit definition
What to know
Garden level, basement level, first floor level, unit, dwelling, elevation, story, street level, building, rental, and classification
Best exam move
Circle first floor; it is the detail most likely to defeat the basement-only distractor.
Topic
Every-rental disclosure
What to know
Every landlord, each tenant, writing, prior to signing, rental property, FEMA Special Flood Hazard Area, 100-year floodplain, landlord awareness, actual knowledge, known flooding, rental property, parking area, frequency, statement, and disclosure
Best exam move
Apply subsection (b) whether the apartment is on the first floor, fifth floor, or in a single-family rental.
Topic
Mapped flood-zone status
What to know
FEMA, Special Flood Hazard Area, SFHA, 100-year floodplain, Flood Insurance Rate Map, map effective date, address search, parcel location, map amendment, awareness, located, not located, unknown, and documentation
Best exam move
Treat mapped status as its own fact and use current FEMA material rather than memory or a marketing description.
Topic
Known property and parking flooding
What to know
Actual knowledge, rental property, real property, parking area, subjected to flooding, frequency, prior event, rainfall, stormwater, access, tenant vehicle, common area, management record, repair record, insurance claim, and disclosure
Best exam move
Do not omit parking-area history simply because water never entered the dwelling unit.
Topic
Additional lower-level disclosure
What to know
Lessor of lower-level unit, garden, basement, first floor, unit flooding, any portion of real property, last 10 years, frequency, written statement, prior signing, written lease, renewal lease, landlord signature, and tenant signature
Best exam move
Use the full property history, not merely the interior history of the unit, and apply the exact 10-year lookback.
Topic
Disclosure form content
What to know
Landlord is aware, landlord is not aware, rental property, FEMA Special Flood Hazard Area, property experienced flooding, number of times, last 10 years, warning outside floodplain, statutory notice, tenant signature, landlord signature, date, and substantially similar
Best exam move
Recognize the required substance even if a lease presents it in a substantially similar layout.
Topic
Timing and placement
What to know
Clearly disclose, in writing, before signing, initial lease, written lease, written renewal lease, included language, signed by both parties, delivery, receipt, review, electronic signature, addendum, property manager, and file copy
Best exam move
A hallway conversation or post-signing email does not satisfy the complete pre-signing and signed-agreement sequence.
Topic
Flood-zone omission remedy
What to know
Landlord failure, subsection (b), tenant later aware, property located in SFHA, written termination notice, no later than 30th day, awareness of failure, advance rent, fees paid in advance, return, no later than 15th day, notice date, and proof
Best exam move
Start the first 30-day clock when the tenant becomes aware of the landlord's failure, not when an unrelated storm occurs.
Topic
Later-flood remedy
What to know
Failure of subsection (b), failure of subsection (c), flood occurs, personal-property damage, habitability, access, termination, written notice, 30 days after flood, advance rent, fees, 15 days, civil action, lost property, damaged property, causation, and evidence
Best exam move
Require both nondisclosure and a flood with one of the listed consequences before selecting this remedy path.
Topic
Exemptions and municipal limit
What to know
Farm lease, concession lease, rental property owned by IDNR, rental property managed by IDNR, Department of Natural Resources, lower-level rental, municipality prohibition, sublease, local code, legal occupancy, and no authorization
Best exam move
An information-disclosure statute does not legalize a basement unit that local law prohibits from being rented.
Topic
Sale disclosure overlap
What to know
Residential Real Property Disclosure Report, flood hazard insurance, flooding, recurring leakage, crawl space, basement, floodplain, seller actual knowledge, buyer, before sales contract, landlord, tenant, lease, separate forms, and separate remedies
Best exam move
Use the seller report for a covered sale and Section 25 for a rental; never swap their parties or deadlines.
Topic
Insurance and risk boundaries
What to know
Flood insurance, renter's insurance, landlord policy, tenant personal property, National Flood Insurance Program, mapped zone, premium, coverage, exclusion, waiting period, lender requirement, policy terms, insurance producer, and no coverage guarantee
Best exam move
Disclosure of flooding does not prove that a landlord policy covers the tenant's belongings or that a particular flood policy is available.
Topic
Broker and property-manager role
What to know
Landlord client, tenant customer, actual knowledge, management file, FEMA record, lease template, written disclosure, signatures, delivery proof, known latent material adverse fact, honesty, false information, attorney referral, insurance referral, and no floodplain certification
Best exam move
Use current records and the statutory lease process while referring zone disputes, remedies, insurance, habitability, and damages to the proper professional.

The FLOOD lease check

  1. Find the transaction. Confirm an Illinois rental, written lease, or written renewal and screen the statutory exemptions.
  2. Locate the unit. Classify garden, basement, and first-floor rentals as lower-level units that receive the extra 10-year inquiry.
  3. Obtain both fact sets. Check current FEMA Special Flood Hazard Area information and the landlord's known history for the rental, property, and parking areas.
  4. Outline the statement. Use substantially similar statutory content, state known frequency, and preserve the outside-floodplain warning.
  5. Deliver and sign. Provide the writing before agreement and include it in the lease or renewal with both signatures.
  6. Distinguish remedies. Use the correct 30-day trigger, 15-day refund deadline, qualifying flood consequence, and personal-property claim.

Which Illinois distinctions matter most?

Terms
All rentals vs. lower-level rentals
Difference
Subsection (b) applies to every landlord and rental. Subsection (c) adds a 10-year property-history rule when the leased unit is garden, basement, or first-floor level.
Question cue
Universal layer plus location-specific layer.
Terms
Flood zone vs. flood history
Difference
Special Flood Hazard Area status comes from FEMA mapping. Flood history records events that actually occurred. A property can have one fact without the other.
Question cue
Mapped probability versus experienced event.
Terms
Unit flooding vs. property flooding
Difference
The 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.
Question cue
Inside dwelling versus anywhere on parcel.
Terms
Rental property vs. parking area
Difference
Subsection (b) expressly makes known flooding of the rental property or any portion of the associated parking areas relevant.
Question cue
Dwelling and vehicle-access areas.
Terms
Prior written disclosure vs. lease inclusion
Difference
The landlord must disclose in writing before signing and must also include the disclosure in the written lease or renewal with both signatures.
Question cue
Advance notice plus signed contract record.
Terms
Initial lease vs. renewal lease
Difference
The 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.
Question cue
Current parties and current agreement.
Terms
30 days after awareness vs. 30 days after flood
Difference
The flood-zone omission path begins when the tenant learns of the landlord's failure. The later-flood path begins when the qualifying flood occurs.
Question cue
Two remedies, two trigger dates.
Terms
Termination refund vs. property damages
Difference
A qualifying termination requires return of advance rent and fees within 15 days after notice. The later-flood path can also support an action for personal property lost or damaged by flooding.
Question cue
Money paid ahead versus loss caused by water.
Terms
Flood vs. recurring leakage
Difference
Section 25 defines flood through inundation from specified water events, including rainfall. A slow plumbing leak may be a defect or habitability issue without fitting that definition.
Question cue
Inundation event versus system leak.
Terms
Landlord flood form vs. seller report
Difference
The 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.
Question cue
Rental transaction versus sale transaction.
Terms
Disclosure duty vs. insurance coverage
Difference
Section 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.
Question cue
Transaction notice versus risk-transfer contract.
Terms
Disclosure compliance vs. legal occupancy
Difference
A 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.
Question cue
Truthful notice does not legalize use.

How does the Illinois rule apply?

A fifth-floor apartment shares a flooded lot

Scenario: A landlord leases a fifth-floor unit in a building outside the FEMA Special Flood Hazard Area. 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

Scenario: 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

Scenario: 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

Scenario: A landlord omitted subsection (b). Six months later, the tenant learns from a current FEMA map that the rental is in the Special Flood Hazard Area.

  1. The statute provides a termination path when the tenant becomes aware of the landlord's failure concerning mapped status.
  2. The tenant's written notice must be sent no later than the 30th day after that awareness.

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

A flood blocks the only entrance

Scenario: 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

Scenario: 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.

Where do candidates misread the Illinois rule?

Trap
Only basement apartments need Illinois flood disclosure.
Correction
Subsection (b) applies to every rental, and subsection (c) adds garden, basement, and first-floor units.
Trap
A first-floor apartment is not lower-level.
Correction
The statutory definition expressly includes first-floor units.
Trap
Outside the FEMA floodplain means no flooding disclosure.
Correction
Mapped status and known event history are distinct, and the form warns of possible flooding outside the mapped area.
Trap
Only water entering the unit counts.
Correction
The statute reaches the rental property, parking areas, and for lower-level units any portion of the containing real property.
Trap
A verbal warning before signing is sufficient.
Correction
The disclosure must be in writing, included in the lease or renewal, and signed by both parties.
Trap
A post-signing addendum automatically cures timing.
Correction
The statute requires disclosure before the lease is signed.
Trap
Every flood-related tenant remedy starts on lease day.
Correction
One 30-day period starts at awareness of omitted zone status and another starts when the qualifying flood occurs.
Trap
The landlord has 30 days to return advance rent after termination.
Correction
The statute uses 15 days after the tenant gives termination notice.
Trap
A later flood always permits termination.
Correction
The path requires a disclosure failure and specified property damage, habitability effect, or access effect.
Trap
The remedy covers every economic loss automatically.
Correction
Section 25 specifically describes advance rent and fees and an action for personal property lost or damaged by flooding.
Trap
The seller report and rental flood form are interchangeable.
Correction
They use different parties, transactions, questions, timing, signatures, and remedies.
Trap
Disclosure proves the tenant has flood-insurance coverage.
Correction
Insurance depends on the tenant's or landlord's actual policy and should be reviewed with an insurance professional.
Trap
A signed flood form legalizes a prohibited basement rental.
Correction
Municipal restrictions remain enforceable, and Section 25 says it does not authorize prohibited lower-level rentals.
Trap
An old summary limited to lower-level rentals states the current law.
Correction
Public Act 104-417 amended the statute effective August 15, 2025; use the current every-landlord text.

Questions students ask about Illinois Flooding Disclosure for Landlords

What flood information must an Illinois landlord disclose?

Before lease signing, every landlord must make the written Section 25 disclosures concerning whether the rental property is in a FEMA Special Flood Hazard Area and known flooding of the rental property or its parking areas, including frequency. The required statement also belongs in the written lease or renewal and must be signed by both parties.

What is an Illinois lower-level unit for flood disclosure?

Section 25 defines a lower-level unit as a garden-level unit, basement-level unit, or first-floor unit. The phrase is broader than basement apartment.

What extra disclosure applies to a lower-level rental?

A landlord leasing a lower-level unit must disclose in writing before lease signing whether that unit or any portion of the real property containing it experienced flooding during the last 10 years and must disclose the frequency. The statement also goes into the lease or renewal and is signed by both parties.

Does a landlord have to disclose flooding outside a FEMA floodplain?

Yes, when the known-history provisions apply. Mapped Special Flood Hazard Area status and actual flooding are separate facts. The statutory form itself warns that a dwelling may still be susceptible to flooding even when the rental is not in the mapped area.

Do parking-lot floods matter under Illinois landlord disclosure law?

Yes. Section 25(b) expressly addresses the landlord's actual knowledge that the rental property or any portion of the parking areas of the real property containing the rental has been subjected to flooding, along with frequency.

When must the Illinois rental flood disclosure be delivered?

It must be clearly disclosed in writing before the lease is signed. The disclosure must also be included in the written lease or written renewal lease and signed by the landlord and tenant.

Can a tenant terminate if flood-zone information was not disclosed?

If the landlord failed to comply with Section 25(b) and the tenant later learns that the property is in the FEMA Special Flood Hazard Area, the tenant may terminate by written notice no later than 30 days after learning of that failure. The landlord then returns advance rent and fees no later than 15 days after the notice.

What if flooding occurs after a required disclosure was omitted?

If the landlord failed to comply with subsection (b) or (c) and a flood damages the tenant's personal property, affects habitability, or affects access, the tenant may give termination notice no later than 30 days after the flood and may bring an action for personal-property damages. Advance rent and fees must be returned no later than 15 days after termination notice.

Which leases are exempt from Section 25?

The section does not apply to farm leases, concession leases, or rental properties owned or managed by the Illinois Department of Natural Resources. It also does not authorize a lower-level rental that a municipality otherwise prohibits.

Are these official PSI Illinois broker exam questions?

No. They are original questions aligned to the Illinois broker outline effective June 24, 2026. Section 25, including Public Acts 103-754 and 104-417, was reviewed through August 1, 2026.
