DE HB217

Requires residential leases that condition security deposit return on key surrender to include a clear procedure for surrendering keys and prohibits requiring key return before the lease term ends

Establishes that if a lease ends on a Saturday, Sunday, legal holiday, or day the leasing office is closed, possession is considered returned when keys are surrendered per lease procedures or the default procedure

Specifies that for leases with multiple tenants, possession is only returned to the landlord when all tenants on the lease have completed the key surrender process

Creates a default procedure when leases lack clear key surrender instructions: tenants may leave keys in the rental unit or leasing office mailbox with written notice to the landlord stating where keys were placed and the return date
