What this form asks for

The AI fills all of it, from your answers or your documents.

The Chicago Residential Lease (by the Chicago Association of REALTORS®) is a binding real estate contract that defines the key terms of a residential tenancy, including lease dates, rent, security deposit or move-in fees, permitted occupants, utilities, and any additional agreements. It is important because it documents the parties’ rights and obligations and helps prevent disputes by clearly stating what is included in the rent, what property is provided, and who is authorized to occupy or receive legal notices. The form also captures required disclosures and practical details (like insurance information, parking, storage, and pet permissions) that affect day-to-day tenancy. Today, this form can be filled out quickly and accurately using AI-powered services like Instafill.ai, which can also convert non-fillable PDF versions into interactive fillable forms.

The AI checks your answers before you download

16 checks built for this form, so a wrong date or a missing answer is caught before anyone else sees it.

Validates Date of Lease is present and in an acceptable date format

Checks that the Date of Lease field is not blank and matches an allowed date format (e.g., MM/DD/YYYY or YYYY-MM-DD) and represents a real calendar date. This is important because the execution date is used to determine enforceability, timelines, and notice periods. If validation fails, the submission should be rejected or routed for correction because an invalid or missing execution date can create ambiguity about when the contract became effective.

Ensures Lease Beginning Date is present, valid, and not after the Lease Ending Date

Verifies the Lease Beginning Date is provided, is a valid calendar date, and occurs on or before the Lease Ending Date. This prevents impossible lease terms and ensures the tenancy start is clearly defined. If the beginning date is missing or later than the ending date, the system should block submission and prompt the user to correct the lease term dates.

Validates Lease Ending Date & Time includes both a valid date and time

Checks that the Lease Ending Date & Time contains a valid date and a time component in an accepted format (e.g., HH:MM AM/PM) and that the time is within 00:00–23:59 (or 1:00–12:59 with AM/PM). This matters because many leases end at a specific time (e.g., noon) and missing/invalid time can cause disputes about possession. If invalid, the system should require correction or defaulting rules must be explicitly confirmed by the user.

Cross-checks Date of Lease against Lease Beginning Date for logical consistency

Validates that the Date of Lease (execution date) is not unreasonably after the Lease Beginning Date (e.g., signed after move-in) unless explicitly allowed by business rules. This helps detect data entry errors and reduces legal/operational risk from backdated or post-dated agreements. If the execution date is after the start date, the system should flag for review or require an acknowledgment/override reason.

Validates Monthly Rent is a positive currency amount with correct precision

Ensures Monthly Rent is provided and is a numeric value greater than 0, formatted as currency (allowing commas and a decimal point) with no more than two decimal places. This is critical for billing, late fee calculations, and accounting integrations. If validation fails, the submission should be blocked because rent cannot be calculated reliably.

Validates Leased Address (Premises) completeness and structure

Checks that the leased address includes required components: street number/name, city, state (must be IL for a Chicago lease unless the system allows otherwise), and a 5-digit ZIP code (optionally ZIP+4). Also validates that an apartment/unit number is provided when the address appears to be multi-unit (e.g., contains 'Apt', '#', 'Unit') or when the user indicates an apartment/condo. If incomplete or malformed, the system should reject or request correction to prevent service/notice and occupancy issues.

  • Requires Security Deposit Amount and Holding Institution details when Security Deposit is 'Yes'

Common Mistakes in Completing Chicago Residential Lease (CAR) V13.0 (2026)

The ones the AI is built to catch.

Using inconsistent lease dates (signed date vs. start/end dates)
People often enter the Date of Lease (signature/execution date) as the Lease Beginning Date, or they pick an end date that doesn’t match the stated term. This can create disputes about when rent is owed, when notice periods start, and when the tenant must vacate. Avoid this by confirming the execution date is the day all parties sign, then separately entering the exact move-in/start date and the correct end date that matches the agreed term. AI-powered tools like Instafill.ai can flag date inconsistencies and enforce valid date formats before submission.
Leaving the lease end time blank or entering an unclear time
The form asks for “Lease Ending Date & Time,” but many people provide only a date or write vague entries like “noon” without specifying AM/PM. Missing or ambiguous end times can cause move-out day conflicts, cleaning/turnover scheduling issues, and disagreements about prorated rent or holdover. Avoid this by entering a specific time (e.g., 11:59 PM or 12:00 PM) and using a consistent format with AM/PM. Instafill.ai can standardize time entries and prevent incomplete end-date fields.
Entering monthly rent in the wrong format or forgetting cents
A common error is writing rent with symbols or text (e.g., “$2,000/mo”) when the field expects a clean numeric amount, or accidentally omitting cents when the agreement includes them. Incorrect formatting can lead to data entry problems, misapplied payments, and disputes over the actual rent amount. Avoid this by entering a numeric dollar amount consistently (e.g., 2000 or 2000.00) and verifying it matches any listing, offer, or rider. Instafill.ai can auto-format currency fields and validate that the rent is a proper number.
Providing an incomplete leased address (missing unit number or ZIP)
Tenants and landlords frequently forget the apartment/unit number, use a nickname for the building, or omit the ZIP code. An incomplete address can cause notice/service issues, confusion about which unit is covered, and problems with insurance, utilities, and legal enforcement. Avoid this by entering the full street address plus unit number, city, state, and ZIP exactly as recognized by USPS and the property records. Instafill.ai can help normalize addresses and catch missing components like unit numbers.
Checking 'Security Deposit: Yes' but not completing the holding institution details
The form explicitly requires the Illinois financial institution name and address when a security deposit is held, but people often leave that section blank or list a non-bank location (e.g., “landlord’s office”). Missing holding information can violate local requirements, create compliance risk, and complicate deposit return disputes. Avoid this by confirming whether a deposit is actually being held and, if yes, entering the full institution name and complete address (street, city, state, ZIP). Instafill.ai can enforce conditional logic so the holding institution fields must be completed when “Yes” is selected.
Confusing a security deposit with a non-refundable move-in fee
Many renters assume the move-in fee is the same as a deposit, or they enter the same amount in both fields. This misunderstanding can lead to incorrect accounting, disputes at move-out, and confusion about what is refundable and what is not. Avoid this by clearly distinguishing: a security deposit is typically refundable subject to deductions, while a move-in fee is non-refundable; enter only what applies and ensure the amounts match the parties’ agreement. Instafill.ai can prompt clarifying checks and reduce duplicate/contradictory entries.
Marking pets as permitted but failing to describe the pet(s) and terms
People often check “Pets Permitted: Yes” but leave the description blank or write something too vague (e.g., “dog”) without breed/size/count or any agreed restrictions. This can cause enforcement problems, disputes over unauthorized animals, and difficulty applying pet-related rules or fees later. Avoid this by listing each permitted pet with clear identifiers (type, number, approximate weight, and any restrictions) and referencing any pet fee/rules in Additional Agreements and Covenants if applicable. Instafill.ai can require a description when pets are marked “Yes” and help format the entry consistently.
Parking and storage fields left blank or filled with unclear identifiers
When parking or storage is included, people frequently forget to list the space number(s) or storage locker ID, or they write “included” without specifics. Lack of precise identifiers can lead to conflicts with other residents, towing disputes, and disagreements about what the lease actually provides. Avoid this by entering exact space numbers and storage locations (e.g., “Space 14, 15” or “Locker B-12”) and using “N/A” only when truly not provided. Instafill.ai can prompt for required identifiers when the “Yes” box is checked and standardize comma-separated lists.
Not attaching Rider 23 when the unit is furnished (or marking furnished incorrectly)
Some parties mark the premises as furnished but forget to attach the Furnished Lease Rider, or they mark “No” even though landlord-provided furniture is present. This can create disputes over what items must remain, what condition is expected at move-out, and who is responsible for damage. Avoid this by confirming whether any furniture beyond standard appliances is included and, if furnished, attaching Rider 23 and listing key items. Instafill.ai can remind users to include required riders when “Furnished: Yes” is selected.
Misstating included utilities and landlord-provided appliances
A frequent mistake is checking utilities that are not actually included (or forgetting to check ones that are), and failing to specify “Other” items clearly. This leads to billing confusion, service interruptions, and disputes over who must set up accounts or pay for services. Avoid this by verifying the exact utility responsibility (water, gas, electric, internet, etc.) and checking only what the rent truly includes; use the “Other” line to name the service precisely. Instafill.ai can help ensure “Other” fields are completed when selected and keep utility selections consistent with the agreement.
Incomplete or incorrect party identification and notice recipient information
People often use nicknames instead of full legal names for tenants/landlords, omit contact details for the landlord/management agent, or leave blank the person authorized to accept service of process and notices. These omissions can make notices ineffective, delay repairs and communications, and create legal complications if disputes arise. Avoid this by entering full legal names for all signing tenants, the landlord or authorized agent’s full contact information, and a clearly identified notice recipient with mailing address and phone/email. Instafill.ai can validate required identity fields and reduce errors from inconsistent naming across the lease.

What is the Chicago Residential Lease form used for?
This form is a binding lease contract used to rent a Chicago-area residential property (apartment, condo, single-family home, or townhome) for a defined term. It documents key terms like rent, dates, deposits/fees, utilities, and occupancy.
Who needs to fill out and sign this lease?
The landlord (or authorized management agent) and all adult tenants who will be responsible for the lease should complete and sign it. Anyone who will live in the unit but is not a tenant should be listed as an authorized occupant if the lease provides a place for that.
What dates do I enter for “Date of Lease,” “Lease Beginning Date,” and “Lease Ending Date & Time”?
“Date of Lease” is the date the agreement is signed/executed. “Lease Beginning Date” is the first day the tenancy starts, and “Lease Ending Date & Time” is the exact end date and time the tenant must vacate (as stated in the lease).
How do I fill in the “Monthly Rent” field—does it include utilities?
Enter the agreed monthly rent amount as a dollar figure. Utilities are only included if you check them under “Rent shall include the following,” so don’t assume utilities are included unless they’re checked.
What address should I use for “Leased Address (Premises)”?
Use the full property address including unit/apartment number, city, state, and ZIP code. This should match the official mailing address used for the property.
When do I check “Security Deposit: Yes,” and what extra information is required?
Check “Yes” if the landlord is holding a security deposit for this lease and enter the deposit amount. You must also provide the name and full address of the Illinois financial institution where the deposit is or will be held.
What if there is no security deposit—only a move-in fee?
Check “Security Deposit: No” and then complete the “Non-Refundable Move-In Fee” section if a fee is being charged. Be sure the fee amount is entered only when the move-in fee is marked “Yes.”
How do I complete the “Pets Permitted” section?
If pets are allowed, check “Yes” and describe the permitted pet(s) (for example: “1 dog, 35 lbs max” or “1 cat”). If pets are not allowed, check “No” and leave the description blank or mark it as N/A.
How do I list parking that’s included with the lease?
Check the box indicating parking is included and list the assigned space number(s) (use commas for multiple spaces). If parking is not included, leave the space field blank or enter N/A and ensure the “No” option is selected.
What should I put for “Additional Storage Location”?
If storage is included, check “Yes” and describe the storage area (e.g., “Storage locker #12,” “Basement cage B-4,” or “Garage shelf”). If none is provided, check “No.”
What does “Furnished?” mean, and when do I attach Rider 23?
Mark “Furnished: Yes” if the unit is being rented with furniture provided by the landlord, and attach Rider 23 (Furnished Lease Rider). If the unit is not furnished, mark “No” and do not attach the rider.
How do I indicate which utilities and appliances are included?
Check the boxes for utilities included in rent (water, electricity, gas, cable, satellite, internet) and specify any “Other” items on the line provided. Separately, check the boxes for landlord-provided appliances (e.g., refrigerator, oven/range, dishwasher, washer/dryer) and list any additional items under “Other.”
Do I need to provide insurance information on this lease?
If the property has 4 units or more, the landlord’s property insurer information is required. If the landlord requires renter’s insurance, the tenant should provide the tenant’s property insurer name, address, and phone number.
What is the “Licensed Broker” checkbox for tenants or landlords?
These checkboxes are disclosures used when a tenant or landlord is a licensed real estate broker in Illinois (and, for the landlord, has a direct or indirect interest in the property). Only check them if they apply and fill in the corresponding name field.
Can AI help me fill out this lease, and how would I do it with Instafill.ai?
Yes—tools like Instafill.ai can use AI to auto-fill form fields accurately and save time by pulling details like names, dates, rent, deposits, and included utilities into the correct fields. Typically you upload the PDF to Instafill.ai, answer a guided set of questions (or import data), review the populated fields, and then download the completed lease for signature.
What if the PDF lease is not fillable (a flat/scanned PDF)?
