What can differ by state?
Security deposit rules can differ on the maximum amount, where money must be held, interest, move-in checklists, inspections, allowable deductions, ordinary wear and tear, itemization, return timing, forwarding-address requirements, tenant demand and remedies.
Deposit alternatives can add a separate product layer
A surety bond or deposit-insurance product can have its own premium, policy term, claim and reimbursement provisions. Use the state deposit guide as the traditional-deposit framework, then verify whether separate state or local rules govern the alternative product.
Start with the facts, then the source
A statewide rule still may not resolve a specific dispute. Lease language, property type, local ordinances, move-in and move-out evidence, invoices and the exact timeline can all matter. The audit keeps those factual inputs separate from the state-law layer.
