Housing (Zoning)

HB 477 revises Utah's land use regulations to streamline municipal processes and expand housing options. It directly affects municipalities by modifying how they handle incorporation feasibility requests, planning commission duties, and approvals for new business uses. Key provisions include requiring certain municipalities to allow detached accessory dwelling units (like backyard cottages) as permitted uses in specific zones, adjusting deadlines for modified incorporation requests, and clarifying when counties can deny building permits for infrastructure issues. The bill makes no changes to funding requirements and takes effect in May 2026.

SB 284 modifies Utah's local land use regulations to streamline processes for cities, counties, and property developers. It directly affects municipal planning commissions, local governments, and residents seeking to build or modify properties by requiring counties to act if planning commissions miss deadlines, clarifying appeal procedures, and mandating that certain municipalities allow detached accessory dwelling units (like backyard cottages) as permitted uses in specific zones. Key changes include updating standards for regulating building heights, simplifying business use approvals, and altering how land use decisions are reviewed for fairness. The bill makes these adjustments without appropriating new funds or changing existing infrastructure fee requirements.

HB 544 requires Utah counties to accept and process plan review applications for single-family dwellings on "qualifying parcels" (land created before county land use ordinances or meeting specific zoning and development criteria) that are not part of a subdivision. The bill mandates counties to review such applications if the proposed building meets setback requirements, utility approvals, health department reviews (where required), and street frontage dedication. It directly affects landowners seeking to build single-family homes on qualifying parcels and counties that must now follow these standardized review procedures. The bill does not require counties to provide infrastructure or alter existing land use authority, focusing solely on streamlining the application process for eligible parcels.

SB 221 amends definitions and administrative procedures for Utah's Housing and Transit Reinvestment Zones, directly affecting municipalities and planning authorities managing these zones. It redefines "base year" for property tax calculations, introduces the term "extraterritorial affordable housing," and adjusts requirements for boundary changes and project approvals. Key provisions include clarifying terms like "developable area" and modifying processes for reviewing investment zone proposals. The bill makes technical updates to Utah Code sections without adding new funding or creating new zones, focusing solely on refining existing framework language.

HB 184 allows property owners to request that municipalities accept "preferred land use regulations" for building starter homes or smaller residential lots, even if current zoning would normally prohibit it. The bill defines a "starter home" as a single-family home sold at or below the local average home price (with two parking spots), and sets a minimum lot size of 5,400 square feet for certain developments. Municipalities must review these requests within five business days, either approving them or denying them with written reasoning; if not denied within 30 days, the request becomes permitted. This process aims to increase housing affordability by streamlining approvals for smaller, more affordable homes without requiring additional engineering plans or design documents.

HB 436 modifies reporting requirements for municipalities implementing moderate income housing strategies and adds a new transportation priority. It requires municipalities to submit detailed annual reports tracking housing strategies, new home construction, and zoning changes, with stricter compliance standards for those without public transit stations. Crucially, it grants priority consideration for transportation projects if a municipality adds 2.5% or more new residential units annually. The bill affects all "specified municipalities" defined under Utah law, with no new state funding required. It takes effect May 6, 2026, and makes technical updates to existing housing reporting codes.
