How Security Deposits Work in the USA
Understanding the security deposit process from move-in to return. Each step has legal requirements that vary by state.
Lease Signing
Landlord collects security deposit at or before lease signing. Amount must comply with state limits. Some states require a written receipt and disclosure of where the deposit is held.
Move-In Inspection
Document the property’s condition with photos and written notes. Both landlord and tenant should sign the move-in checklist. This protects both parties when determining deductions later.
Deposit Holding
Landlord holds deposit in a separate bank account. Some states require interest-bearing accounts. Commingling deposit funds with personal funds is illegal in many states.
Move-Out Inspection
Landlord inspects the property and documents any damage beyond normal wear and tear. Many states require the tenant to be present during the inspection if requested.
Deposit Return
Landlord returns deposit minus itemized deductions within the state’s deadline. Missing the deadline can result in penalties including full deposit forfeiture or statutory damages.
