Wisconsin Security Deposit Laws: Limits, Returns, and Deductions

Wisconsin's security deposit rules, resting on the foundation of property laws established since Wisconsin statehood in 1848, are governed by ATCP 134.06 and are enforced by the Department of Agriculture, Trade and Consumer Protection (DATCP). These rules cover everything from move-in inspection rights to strict return deadlines.

Security Deposit Limits

Wisconsin is one of a handful of states that does not impose a clear statutory maximum on security deposits for most residential properties. However:

• Industry standard in Wisconsin is one to two months' rent.
• Under ATCP 134.06, any rent prepayment in excess of one month's prepaid rent is considered a security deposit.

Move-In Inspection Rights

Before collecting any security deposit, the landlord must inform the tenant in writing of two critical rights:

1. 7-Day Inspection Window: The tenant has the right to inspect the premises and document pre-existing damage within 7 days of moving in.
2. Previous Tenant's Damage List: Before accepting a security deposit, the landlord must notify the tenant in writing that the tenant may request a list of physical damages or defects, if any, charged to the previous tenant's security deposit (ATCP 134.06(1)(a)2).

Best Practice: Provide a written move-in checklist and conduct a joint walk-through with the tenant, photographing every room. This is your primary defense against deposit disputes.

What Can Be Deducted

Permissible deductions from the security deposit include:

1. Unpaid Rent: Any rent or utility bills the tenant failed to pay.
2. Damage Beyond Normal Wear and Tear: Actual cost to repair tenant-caused damage (holes in walls, stained carpets from negligence, broken fixtures).
3. Lease Violations: Financial losses resulting from a breach of the rental agreement.

What is NOT Deductible

• Normal Wear and Tear: Faded paint, worn carpet from ordinary use, small nail holes.
• Pre-Existing Damage: Any condition documented on the move-in checklist.
• Routine Cleaning: Unless the tenant left the unit in a condition substantially dirtier than at move-in.

Return Deadline: 21 Days

Landlords must return the full deposit or the balance remaining after lawful deductions within 21 calendar days after the tenant vacates the property, abandons it, or is evicted.

Itemized Statement

If the landlord withholds any portion of the deposit, they must provide a written itemized statement detailing each deduction and its cost within the same 21-day period.

Penalties for Non-Compliance

Wisconsin law (ATCP 134.06 and Chapter 704) does not explicitly state that landlords forfeit their right to retain any portion of a security deposit or are liable for double damages plus attorney fees for failing to return a deposit within 21 days. However, case law (e.g., Pierce v. Norwick) addresses damage claims for non-compliance with these regulations.

Interest on Deposits

Wisconsin law (ATCP 134.06 and Chapter 704) does not explicitly address whether landlords are required to pay interest on security deposits.

Best Practices for Landlords

1. Use a Move-In/Move-Out Checklist: Document everything with timestamps and photos.
2. Set a 21-Day Calendar Reminder: Never miss the return deadline.
3. Keep Receipts: For every repair you deduct from the deposit.
4. Separate Accounts: While not legally mandated, holding deposits in a separate bank account simplifies bookkeeping and protects against commingling claims.
