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.
