SB 181 Utah Senate · 2025 General Session

Housing Affordability Amendments

SB 181 limits local government regulations on single- and two-family home construction to increase housing affordability. It prohibits municipalities and counties from requiring specific building design elements (like exterior colors or roof styles) or imposing parking space size limits (e.g., max 10 feet wide for enclosed spaces) for most homes. The bill specifically exempts owner-occupied affordable housing - defined as housing priced at 80% of the county median home price - from mandatory garage requirements. These changes apply to "specified" municipalities and counties under Utah law, aiming to reduce development costs without altering existing historic district or flood program rules.
