R-2 Zoning in Oklahoma City — Setbacks, Height, and Use Rules
R-2 in Oklahoma City is the two-family residential district. It allows both single-family and two-family (duplex) dwellings by right and is most commonly found in transition zones between R-1 single-family neighborhoods and denser R-3 or commercial corridors. Significant R-2 inventory exists in near-northeast OKC, midtown fringe areas, and portions of south OKC.
R-2 carries slightly smaller lot minimums than R-1 — typically 5,000 sq ft per dwelling unit for two-family — allowing a duplex on a 10,000 sq ft lot. Single-family uses are also allowed by right on R-2 lots, giving property owners flexibility.
R-2 is often targeted for infill development in OKC's ongoing housing supply initiatives. The code treats duplexes with the same design standards as single-family homes (setbacks, height, parking) to keep the streetscape consistent.
