Irving, TX Building Setbacks & Zoning: Structure Height Limits (2026)

The Irving Unified Development Code sets district-specific height ceilings in Chapter UDC-2's residential district standards. 5 Single-Family Residential district, applied across most of Irving's older subdivisions, limits the principal structure to two stories or 25 feet and caps lot coverage by the principal building at 40 percent of total lot area. 8(e). 6(e) apply the same 2½-story, 30-foot ceiling to R-15 and R-10, at 30 and 40 percent coverage respectively. 1(a) of the UDC modifies these numeric caps for specific building features: chimneys, water towers, penthouses, cupolas, domes, spires, standpipes, parapet walls and similar mechanical appurtenances may exceed the district height limit under separate city ordinance rather than being held to the 25 or 30-foot cap.

1(b) addresses through lots with double frontage, allowing height to be measured from curb level on either street when the lot is 150 feet deep or less; on deeper through lots, the street permitting the greater height governs only the first 150 feet, and the remainder follows the lower-elevation street's rule. A building permit application that exceeds the applicable district cap is rejected by the Community Development Department during plan review; owners seeking relief from the numeric limit must pursue a variance or site-plan rezoning rather than build first.
