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

1 of the Bell County Subdivision Regulations fixes the setback lines that must appear on every plat approved in the unincorporated county, adopted, the section states, in accordance with Chapter 233 of the Local Government Code. On a major highway or road, the front setback line runs 50 feet from the edge of the right-of-way. On any other public road, the front setback drops to 25 feet from the edge of right-of-way, except within the turn-around portion of a cul-de-sac, where the minimum narrows further to 15 feet from the right-of-way edge.

1 is the county's only generally applicable building line rule for new subdivisions; it operates as a plat-approval requirement enforced by the County Engineer and Commissioners Court rather than a zoning setback enforced through a building permit. The line has to be shown on the face of the plat itself under § 301's broader lot-and-easement requirements, alongside utility easements of at least 10 feet at the front or rear of each lot. 1 governs new plats going through Bell County's Chapter 232 platting process, not existing improvements or property inside an incorporated city, where Killeen, Temple, Harker Heights and the county's other municipalities each set their own building lines.
