Local Land Use Regulation Restrictions
SB 152 limits the ability of Utah municipalities to regulate the design of one- and two-family dwellings. The bill defines “building design element” broadly to include features such as exterior color, cladding, roof style, porch design, window and door placement, garage door styling, room count, interior layout, minimum square footage, rear yard landscaping, minimum building dimensions, and front yard fencing. Under the bill, cities and towns generally may not require these design elements for one- or two-family homes.
The substitute bill adds a new category called a “housing-restricted community,” meaning a municipality in a county of the first or second class, and bars those municipalities from requiring a garage—attached or detached—on a one- or two-family dwelling. The bill preserves a number of exceptions, including historic districts, flood insurance program requirements, wildland-urban interface rules, development agreements, certain older residential areas, rear-yard water-efficient landscaping, cladding rules tied to construction defects, owner-requested zoning incentives, and explosion-mitigation ordinances. The bill takes effect May 7, 2025.
The bill amends Utah Code Section 10-9a-534 and further constrains local land use authority over residential building design standards. Its practical effect is to prevent municipalities from using design regulations to mandate garages in qualifying housing-restricted communities and to reinforce existing statewide limits on local control over aesthetic and layout requirements for small residential dwellings. The bill affects municipalities, developers, and homeowners by reducing local discretion in zoning and design review for one- and two-family housing, while preserving targeted exceptions for safety, historic preservation, and negotiated development conditions.
The available voting record suggests the bill was received favorably in committee, with a 4-0 vote for both substitute recommendation and being held. No committee transcript is available, so there is no recorded debate to indicate broader support or opposition. Based on the bill’s structure and the committee vote, the general sentiment appears to be supportive, at least at the committee level, with interest in advancing the substitute version.
The main point of contention is likely the balance between statewide housing policy and municipal home-rule authority. Supporters would view the bill as reducing regulatory barriers and construction costs for smaller homes, especially by preventing garage mandates in housing-restricted communities. Opponents or concerned local governments may see it as an intrusion on local planning discretion and neighborhood design standards. The garage prohibition in particular is the most notable expansion of state preemption, though the bill’s many exceptions show an effort to preserve local and safety-related controls.
