Interested in getting some extra income with converting the extra space in the basement into a rentable unit.Basements in a one-family home can be lawfully rented only if the following conditions are met:Compliance with the Housing Maintenance Code for minimum room size.There is a minimum ceiling height of 7 ft.The walls, as high as ground level, must be damp- and water-proofed if HPD determines that subsoil conditions on the lot require it.The basement is occupied by one family and does not include boarders.Every room must have at least one window.The bottom of any yard or other required open space cannot be higher than six inches below the window sill of any required window in the room.

The area is expanding rapidly and I could see this property really going up in value as there is a very limited amount of buildable space between the mountains and the ocean, so I see this as a great investment and I would love to keep it.
