What this means in practice
Landlords: state the deposit amount, where it is held and how it will be returned in the lease, and send the refund with any deductions in writing within the deadline.
Tenants: record the unit's condition with photos and a move-in checklist, keep your receipts, and give the landlord a forwarding address in writing when you move out.
Both sides: normal wear and tear is generally not deductible. Disputes over deductions usually go to small claims court.
General information, not legal advice. Laws change, and cities can add their own rules, so check the current statute before you rely on it.
