Summary
Houston has no zoning height district, but its Multi-Unit Residential (MUR) performance standards under Chapter 42 cap any 3-to-8-unit residential development at 30 feet, measured from average grade to the highest roof surface. The rule reached the Code of Ordinances through Ordinance No. 2023-801, part of the platting standards that substitute for zoning.
(8)Building height may not exceed 30 feet as measured from average grade to the highest roof surface. Roof surface is defined, in accordance with Section D of the International Fire Code, as the measurement to the eave of a pitched roof, the intersection of the roof to the exterior wall, or the top of a parapet wall, whichever is greater.
Full Breakdown
Because Houston has never adopted zoning, there is no citywide zoning height district. What controls building height on small multifamily lots instead is Section 42-237 of the platting and subdivision chapter, added by Ordinance No. 2023-801 (eff. Nov. 27, 2023) to create the Multi-Unit Residential (MUR) track: a site with at least three but no more than eight dwelling units, on a minimum 50-foot-wide, 3,500-square-foot lot no more than 150 feet deep. " The same section layers on other MUR performance standards that interact with bulk near the height line: a 5-foot building line along most public streets, widening to 15 feet on major thoroughfares with an 80-foot-or-less right-of-way, a 4-foot cap on any front-yard fence, and a minimum of one guest parking space for every six dwelling units on top of the parking required by Section 26-492.
The 30-foot figure is not a suggestion, it is a plat and development-plan performance standard: an applicant's subdivision plat or development plat must show compliance before the Planning and Development Department will approve it. Nothing in Section 42-237 extends the 30-foot cap to detached single-family homes; those instead follow the building-line rules of Sections 42-156 and 42-157, which regulate setback distance rather than height.
Violations & Fines
A project that exceeds the 30-foot height ceiling, or otherwise fails the MUR performance standards in Section 42-237, cannot get its subdivision or development plat approved by the Planning and Development Department, since the required plat notations must certify compliance before recordation. Built noncompliance is caught and corrected through the city's standard building-permit and certificate-of-occupancy review rather than a standalone fine schedule tied to this section.
