A Basement Apartment Done Wrong Is A Liability, Not An Asset
An unpermitted basement unit can•t be legally rented, won•t appraise, and becomes a problem the day you sell. Low ceilings, bad egress, no certificate of occupancy. Plenty of DC owners have poured money into a basement that the District won•t let them rent.
PAT Construction delivers 100% code-compliant English basement conversions with proper underpinning, egress windows, fire separation, and Certificates of Occupancy.
