In the Residential-One (R-1) district, the primary-structure front setback is 30 feet, side setbacks are 5 feet minimum with 15 feet total, and side setbacks adjacent to a local or collector street are 20 feet (30 feet at an arterial). Setbacks vary by zone district.
Section 30 of the Zoning Resolution sets minimum setbacks per residential district. In R-1, primary structures and garages have a 30-foot front setback (and a 30-foot front setback adjacent to an arterial). Each side setback must be at least 5 feet with both sides totaling 15 feet or more; side yards adjacent to a local/collector street are 20 feet and 30 feet at an arterial. Other districts (RR, R-2, R-3, R-4) carry different figures. Setbacks are measured from the foundation or wall, though eaves, overhangs and fireplaces may protrude 24 inches into the setback.
Structures built inside a required setback are zoning violations and may require a variance, relocation, or removal; a certified setback verification may be required before framing.
