How long does a landlord have to return a security deposit in Maryland?
In Maryland, the deadline is 45 days after move-out. That clock runs from move-out and the return of possession, not from the end of the lease.
Maryland law sets the maximum deposit at 1 month's rent (for leases signed on/after October 1, 2024); 2 months for prior leases.
Missing the deadline has teeth. Across states, remedies range from losing the right to any deduction to penalty damages plus the tenant's attorney's fees. The itemized deduction statement has to arrive inside the same window to preserve any deduction at all.
