Keller, TX Building Setbacks & Zoning: Setback Rules (2026)

Keller administers building setbacks through its Zoning Ordinance, which divides the city into districts such as SF-36, SF-30, SF-20, SF-15, SF-12, SF-10, SF-8.4, MF-12, MF-18, and commercial classes. Each district specifies minimum front, side, and rear yard dimensions. Typical single-family setbacks in Keller range from a 25-foot front yard in most SF districts up to 30 feet in the lower-density large-lot districts, a 10-foot side yard with 15 feet on a corner street side, and a rear yard of 20 to 25 feet. Minimum lot sizes and width are also tied to the district. Accessory buildings such as detached garages, storage sheds, and pool houses generally have reduced rear and side yard setbacks, often 5 feet, and may not be placed in front yards. Setbacks are measured from the property line to the closest wall or roof overhang, with allowances for eaves and bay windows projecting a limited distance. Variances for undersized lots or reduced setbacks require application to the Zoning Board of Adjustment, which considers hardship, neighborhood compatibility, and platted conditions. Planned developments and master-planned subdivisions frequently establish their own setbacks through PD zoning or recorded plats, which supersede base district requirements. Before building any new structure, addition, or accessory building, owners should verify setbacks with Development Services at 817-743-4020.
