HB 90 Utah House · 2025 General Session

Zoning Amendments

HB 90 modifies zoning rules in Utah's urban municipalities by allowing detached single-family homes on lots of at least 6,000 square feet in residential zones. This directly affects homeowners, developers, and local governments in cities within first or second-class counties (defined as "urban municipalities" in the bill). The key change removes previous restrictions on lot size for single-family homes in these areas, making such construction a standard permitted use. The bill makes technical updates to Utah Code sections 10-9a-505 and adds a new section (10-9a-505.1) to formalize this rule, with no additional costs or procedural changes. It takes effect on May 7, 2025.

Introduced Substitute #1 · 3 edits
MINOR
The bill was amended to increase the minimum lot size for detached single-family homes from 4,000 to 6,000 square feet in residential zones of urban municipalities. The highlighted provisions were also updated to reflect this change while removing a provision that allowed housing in commercial zones. This makes it more difficult to build single-family homes in smaller lots within urban areas.
Scope change
The scope of the bill was narrowed by removing the provision that made housing a permitted use in commercial zones of urban municipalities.
