Norman, OK Building Setbacks & Zoning: Setback Rules (2026)

NCC 36-514 governs area regulations for the R-1, Single-Family Dwelling District, Norman's principal detached-home zone. The front yard "shall be set back from street right-of-way lines" to a minimum depth of 25 feet, and on a double-frontage lot the requirement applies to both streets unless a limits-of-access line has been established across the rear. Side yards must be at least five feet wide for the principal building, with unattached one-story accessory buildings, including ADUs, also set back five feet from the side line (reducible to three feet if located more than 50 feet from the rear property line).

Corner lots carry extra setback: a main building must sit back 15 feet from the intersecting street right-of-way where the lot is back-to-back with another corner lot, and 20 feet in every other case, while a garage facing a street can never sit closer than 20 feet to that street's property line. The rear yard must be at least 20 feet deep or 20 percent of the lot's depth, whichever is smaller, and accessory buildings along a rear utility easement or alley need only a one-foot setback.

Minimum lot width is 50 feet at the building line with at least 35 feet of street frontage, and total lot area must be at least 6,000 square feet. NCC 36-515 modifies these figures for the R-1-A Attached Dwelling District, and NCC 36-544 sets citywide open-space exceptions, including a corner-lot sight-triangle rule restricting fences, walls and plantings over three feet within 30 feet of the corner.
