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

The City of Killeen regulates yard setbacks district by district inside chapter 31 of the code of ordinances rather than through a single dimensional table. In the "R-1" single-family residential district, Sec. 31-188(a) requires a front yard of not less than 20 feet, with no parking allowed inside that required front yard. Side yards must be at least 5 feet wide, rising to 15 feet where a side yard adjoins a side street, and nonresidential uses on an R-1 lot need a 25-foot side yard.

The rear yard must run at least 25 feet, measured from the centerline of the rear easement used in the subdivision ordinance. The "SF-2" single-family district carries a matching 20-foot front yard and 5-foot side yard under Sec. 31-195(b), but its rear yard minimum drops to 20 feet, five feet shallower than R-1. Builders who cannot meet a required depth because of an odd lot shape or an existing pattern of shallower yards on the same block can ask the board of adjustment for a modification under Sec.

31-472(a), which lets the board relax front yard rules where hardship or an established nonconforming setback line already exists on 25 percent or more of the block face. Open, unenclosed porches, terraces, eaves and roof extensions may project up to 4 feet into a required front yard under the same section, and a gas station canopy may extend to within 12 feet of the property line. Every new house, addition or fence-line structure is checked against these district-specific figures when the building inspections division reviews a building permit application, so the operative number always depends on which zoning district the lot carries, not a single citywide rule.
