Security Deposits in Michigan Commercial Leasing

Michigan legislation governing security deposits-specifically the Landlord and Tenant Relationships Act (Act 348 of 1972) with its strict 1.5-month caps and 30-day return policies-explicitly excludes commercial tenancies.

In the Michigan commercial real estate sector, security deposits are completely unregulated by statute.

No Statutory Limits or Return Deadlines

Because there is no prevailing state law regarding commercial deposits:

1. There is no cap on the amount. A commercial landlord in Detroit can demand the equivalent of six months of gross rent as a security deposit, provided the tenant signs the lease.
2. There is no legal requirement to hold the funds in a regulated escrow account or secure a surety bond (unless deliberately drafted into the commercial lease).
3. There is no statutory 30-day deadline to return the deposit after the tenant moves out.

The entire process is governed exclusively by what is written in the lease agreement. If the lease states the deposit will be returned within 60 or 90 days after vacating to allow the landlord to audit the final year's NNN outgoings statement, Michigan courts will enforce that 90-day waiting period.

Methods of Holding Commercial Security

For high-end industrial or retail properties, requiring massive upfront cash deposits is often impractical for the tenant's operating cash flow and creates liabilities for the landlord. Michigan commercial landlords frequently rely on alternative security instruments.

Letters of Credit (Bank Guarantees)

The gold standard for commercial security in Michigan is an irrevocable, unconditional Letter of Credit.

Instead of depositing $80,000 cash into the landlord's account, the tenant's commercial bank issues a formal guarantee. If the tenant breaches the lease, the landlord presents the Letter of Credit to the bank, and the bank pays the landlord the requested funds (up to the $80,000 limit) unconditionally.

• Advantage: If the commercial tenant files for bankruptcy, a cash deposit held by the landlord might become tied up in federal bankruptcy court as "property of the debtor's estate." A Letter of Credit belongs to the bank, not the tenant, allowing the landlord to cleanly access the funds to cover lost rent despite the bankruptcy filing.

Personal Guarantees Because many commercial tenants are insulated behind Limited Liability Companies (LLCs), landlords often require a "Personal Guarantee." The individual owner of the business signs a separate legal document promising that if the LLC defaults on the commercial lease, the landlord can legally seize the owner's personal assets (their house, cars, personal bank accounts) to cover the lost rent.

Managing the Security

While you are not bound by the state's 14-day location notice requirement for commercial leases, you must rigorously track your commercial security instruments. A lapsed $250,000 Letter of Credit that an administrative assistant forgot to renew leaves a landlord completely exposed. Landager systematically tracks expiration dates and "top-up" thresholds for complex commercial security instruments, ensuring your multi-million dollar Michigan portfolio is constantly collateralized.
