RS-4 Zoning in Tulsa — Cottage Court and Infill
RS-4 supports compact single-family infill, cottage courts, and small-lot subdivisions in Tulsa. It is common in Pearl District infill and Kendall-Whittier rebuilds.
RS-4 requires a 4,000 square-foot minimum lot, 40-foot width, and 55% maximum lot coverage. The 15-foot front setback and 4-foot side setbacks support a more urban development pattern.
