Summary
DC zoning caps a residential private garage at 900 square feet and bars any repair or service facilities beyond battery or EV charging. A structure with equipment to repair motor vehicles is a separate "Garage, Repair" use, which residential (R) zones do not allow as a home occupation or accessory use.
Garage, Private: A building or other structure, or part of a building or structure, not exceeding nine hundred square feet (900 sq. ft.) in area, used for the parking of motor vehicles and having no repair or service facilities other than a means by which to charge batteries or an electric vehicle. ... Garage, Repair: A building or other structure, or part of a building or structure, with facilities for the repair of motor vehicles, including body and fender repair, painting, rebuilding, reconditioning, upholstering, equipping, or other motor vehicle maintenance or repair.
Full Breakdown
Title 11 DCMR splits garages into distinct defined uses. " That repair-garage use belongs in Production, Distribution, and Repair (PDR) zones, not the residential house (R) zones. 1's exhaustive home-occupation list covers business support services, cosmetology, dressmaking, home offices, tutoring, and similar low-impact trades. Motor vehicle repair is absent from both lists. A homeowner who installs a lift, paint booth, or repair bay in a residential garage is operating a Garage, Repair use in a zone where the Zoning Administrator has not authorized it as a matter of right, a home occupation, or an accessory use, which is a zoning violation independent of any business license question.
The 900-square-foot cap also matters on its own: a private garage larger than that threshold no longer fits the "Garage, Private" definition regardless of what equipment it holds.
Violations & Fines
Operating a home vehicle repair business without matter-of-right or special-exception zoning authority is enforced by DC's Department of Buildings (successor to DCRA) as a zoning use violation, which can bring a stop-work order, denial or revocation of a Home Occupation Permit, and civil fines under the District's zoning enforcement authority. A property owner can seek relief only through a special exception from the Board of Zoning Adjustment, not a matter-of-right home occupation permit.
