Utah SB 174 (2022)
§ SB 174 — Single-Family Housing Modifications
Research notes
Limits certain local restrictions on single-family housing intended to prevent overly restrictive lot size and design standards. Utah retains general local zoning authority; this is a narrow guard-rail on residential SF standards rather than a density preemption.
