The Rockwall City Planning and Zoning Commission voted 6-0 on July 14 to recommend a text amendment to the Unified Development Code that would allow new HUD-code manufactured homes by right in the Single-Family Estate 4.0 zoning district.
Staff planner Ryan told commissioners the change responds to a state law adopted during the 89th legislative session that takes effect Sept. 1, 2026, and requires cities to permit HUD-code manufactured homes in zoning districts shown on the city map. "What you're considering tonight is really where we're allowing the manufactured home," Ryan said, explaining the draft ordinance aims to comply with the new statute while reducing the risk of inconsistent development in smaller-lot neighborhoods.
To limit potential incompatibility with established subdivisions, the draft includes conditional standards: units must be new HUD-code manufactured homes, have a minimum area of 1,800 square feet (effectively double-wide rather than single-wide), and be set on a permanent concrete foundation, Ryan said. The commission discussed whether the change is effectively compelled by state law. "So really we're, I mean, even if you voted no... it's not gonna matter," Commissioner Bentley said, noting state preemption.
Commissioners asked whether the proposed approach would allow manufactured homes across other plan development districts; staff said many smaller, established plan developments regulate form and would remain protected by other UDC standards and the residential infill SUP process. After discussion, Commissioner Roth moved to approve Z2026-033 as written; the motion passed 6-0 with one commissioner absent. The item will be forwarded to the City Council for final action.
What happens next: the Planning and Zoning Commission’s recommendation goes to City Council on the meeting schedule set by staff. If Council adopts the amendment, the city’s UDC will reflect the new state requirements plus the local conditional standards described above.
