Wisconsin Commercial Security Deposit Laws

Wisconsin commercial security deposits are not regulated by ATCP 134 (which applies only to residential tenancies). This means that the collection, holding, and return of commercial deposits are governed almost entirely by the negotiated lease agreement.

No Statutory Deposit Limits

There is no statutory cap on commercial security deposits in Wisconsin. Landlords can require one month, three months, six months, or more as a security deposit. The amount typically depends on:

• The tenant's business credit history and financial statements.
• The length of the lease term.
• The landlord's investment in tenant improvements (TI allowances).
• Whether a personal guaranty is provided.

No Escrow or Interest Requirements

Unlike residential deposits (which have a 21-day return rule), Wisconsin law imposes no specific escrow, interest, or return deadline requirements for commercial security deposits.

The landlord is not required to:

• Hold commercial deposits in a separate bank account.
• Pay interest on the deposited funds.
• Return the deposit within any particular statutory timeframe.

All of these terms should be clearly defined in the lease agreement. If the lease is silent, courts will generally expect a "reasonable" return period (typically 30–60 days).

Common Lease Terms for Commercial Deposits

Well-drafted Wisconsin commercial leases typically include:

1. Deposit Amount: Stated clearly, often expressed as a multiple of monthly base rent.
2. Permitted Deductions: Unpaid rent, unpaid CAM/NNN charges, property damage beyond normal wear and tear, holdover rent, attorney fees for lease enforcement.
3. Return Timeline: A clearly stated window (e.g., 30, 45, or 60 days after lease termination).
4. Application Against Final Rent: Whether the tenant can apply the deposit to the last month's rent. Landlords almost universally prohibit this.
5. Replenishment Clause: If the landlord draws on the deposit to cover a partial default, the tenant must replenish it to the original amount within a specified period.

Letter of Credit Alternative

For large commercial deals, many Wisconsin landlords accept an irrevocable standby letter of credit (LOC) instead of a cash deposit. This protects the landlord's interests while allowing the tenant to preserve working capital. The LOC should be:

• Issued by a reputable financial institution.
• In a "clean" format that allows the landlord to draw with minimal documentation upon a declared default.
• Auto-renewing (evergreen) for the full lease term.
