My husband and I are considering buying a duplex where the bottom floor is in the basement. Due to coding/zoning laws there is only a 1/2 bath in the basement. We would like to turn it into a full bath and make a master suite downstairs. Has anyone else done anything similar? Was it hard to find a contractor to do the work? What happened when you went to sell the apartment? Any guidance is much appreciated!

  1. The space you describe sounds like a cellar, not a basement. Plumbing fixtures are legal where more than 50% is above grade. Code wise as mentioned above, a room in a cellar would be a recreation room, not a bedroom or living room.

  2. Basements that are less than 50% above grade are not habitable – meaning, no sleeping, cooking, bathing allowed.

    Sure, alot of people put bedrooms and bathrooms in these basements, but legally it’s not allowed and will not get approved by DOB.

    Also, if you’re buying into a Co-op / Condo, they will or should follow DOB guidelines. You’ll need to get their approval before filing with DOB and doing any construction.

    If your basement is more than 50% above grade, there are other consideration. Do you have enough window area? Do you have enough operable window area? Yes, there’s a difference, And you’re going to have to show that when you file your drawings.

  3. We looked at an apartment with an illeagal full bath in the basement and were told that, prior to sale, the owner would sheetrock over the shower (in effect, making the illeagal shower ‘disappear’ for closing) and then the buyers could rip down the sheetrock once the deal went through. There were other reasons we didn’t want the apartment, but going through that process was on the list.
