Texas City, TX Building Setbacks & Zoning: Lot Coverage Limits (2026)

Texas City Code of Ordinances § 160.006 defines lot coverage as the percentage of the total area of a lot occupied by the base (first story or floor) of buildings located on the lot. The limit itself is set in each district's area and height table in chapter 160, so the number depends on the zoning of the parcel in Texas City, Galveston County.

District A, single-family residential (§ 160.024(D)), sets maximum lot coverage by the principal structure at 40%, alongside a 6,000 square foot minimum lot area per dwelling unit, a 25 foot front yard, a 20 foot rear yard and a 5 foot minimum side yard. District A-1 (§ 160.025(D)) also sets 40%, with a 8,200 square foot minimum lot area and a 30 foot front yard.

District A-2, patio homes (§ 160.026(D)), sets 50% for the principal structure and adds a second cap: maximum lot coverage by structures, driveways and parking of 60%. That second figure works as the impervious limit for the lot. District B (duplex) uses 40% and 60% in the same pairing.

Non-residential districts print their caps on structures and on structures, driveways and parking. District O-P (§ 160.032(D)) and District D (§ 160.033(D)) allow 40% for structures and 90% including driveways and parking. District C (multi-family) allows 50% for structures and 70% for driveways and parking. District E-1, Central Business, prints 100% for both.

The Building Official enforces the numbers at permit time. Under § 160.111 an applicant must file a plan in duplicate, drawn to scale, showing the dimensions of the lot and the location and dimensions of the building on the lot with measurements from all lot lines, and no permit issues unless the plan shows conformity with chapter 160.
