Wisconsin Security Deposit Laws: Limits, Returns, and Deductions

Wisconsin's security deposit rules 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:

• The deposit must not be discriminatory in nature (e.g., charging more based on race, familial status, or disability).
• Industry standard in Wisconsin is one to two months' rent.
• For mobile homes, the deposit is capped at the lesser of two months' rent or $750.
• Fees labeled "pet deposits," "cleaning deposits," or "key deposits" are all considered part of the overall 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. Move-Out Itemized List: The tenant has the right to request an itemized list of damages for which funds may be withheld from the deposit at the end of the tenancy.

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 courts take security deposit violations seriously:

• If a landlord fails to return the deposit within 21 days, they may forfeit their right to retain any portion of the deposit—even if the tenant genuinely caused damage or owes rent.
• A tenant can sue for up to double the amount wrongfully withheld, plus reasonable attorney fees and court costs.

Interest on Deposits

Wisconsin law does not require landlords to pay interest on security deposits. Interest is only owed if the lease agreement explicitly requires it.

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.
