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

Haltom City zoning regulates lot coverage in two ways: building coverage (footprint of principal and accessory buildings as a percentage of lot area) and total impervious cover (all surfaces that prevent water infiltration: buildings, concrete, asphalt, patios, pool decks, sport courts). Typical single-family residential district standards limit principal building coverage to 40 percent of the lot, accessory building coverage to 30 percent of the rear yard, and total impervious surface to 60 to 65 percent of the lot area. These limits protect neighborhood drainage, reduce stormwater runoff into the Haltom City drainage system tributaries to the Trinity River, preserve green space, and prevent overcrowding of lots. Commercial and multi-family districts have higher building coverage allowances (60 to 80 percent) but often require enhanced stormwater detention or pervious paving to compensate. Corner lots are measured the same way with total lot area as the denominator. Swimming pools and hot tubs count as impervious cover. Decorative water features and pervious pavers with proper base may be credited as semi-pervious depending on design. Synthetic turf over compacted base typically counts as impervious. Gravel driveways may be permeable if maintained properly. Exceeding the coverage limit requires a variance from the Zoning Board of Adjustment or a Planned Development rezoning. Teardown-rebuild projects must design to current coverage standards even if the original home exceeded them (nonconforming coverage is lost when the structure is demolished). Before planning large additions, patios, or accessory buildings, homeowners should measure existing impervious surfaces and calculate remaining allowance. Floodplain lots have additional stormwater requirements.
