Why West Valley City
West Valley City sits in the Salt Lake Valley at roughly 4,300 feet elevation with a semi-arid climate — cold snowy winters, hot dry summers, and a distinct inversion season in January and February. The city is the second-largest in Utah and one of the most diverse, with a strong working-class housing market, the Maverik Center, and good transit access to downtown Salt Lake City via TRAX light rail. Cost of living runs roughly 10–15% below Salt Lake City proper, making it an attractive ADU market for homeowners looking to add rental income.
Zoning & Placement
In West Valley City, Utah's second-largest city, tiny homes on wheels (THOWs) are classified as recreational vehicles and cannot serve as a primary residence on a standard residential lot. Foundation-built tiny homes are regulated under the Utah State Construction Code, which adopts the 2021 IRC including Appendix Q for dwellings under 400 square feet. West Valley City's zoning code recognizes accessory dwelling units under Utah SB 174 (2021), which requires the city to permit at least one internal ADU by right in owner-occupied single-family homes in residential zones. Detached ADUs are permitted in several residential districts subject to setback, height, and lot-coverage standards. As of April 2026, verify current requirements with the West Valley City Community and Economic Development Department.
Verify current requirements with your local planning department.
What to verify locally
- • Confirm whether your tiny home will be treated as an ADU, a site-built dwelling, or a recreational vehicle.
- • Ask about utility hookup requirements, especially sewer, electrical service, and emergency-access setbacks.
- • Check whether long-term occupancy is allowed on the lot type you are considering.
- • Verify minimum square footage requirements for your zone classification.
ADU & Backyard Tiny Homes
West Valley City follows Utah's SB 174 framework, allowing at least one internal ADU by right in owner-occupied single-family homes across residential zones. SB 44 (2024) further limits the impact fees and design conditions the city can apply. Detached ADUs are permitted in R-1, R-2, and several mixed-use districts subject to a maximum size (typically 50% of primary dwelling floor area or 1,000 square feet, whichever is less), minimum side and rear setbacks, and a height cap tied to the underlying zone. Off-street parking is limited to one additional space. Permits run through the West Valley City Community Development Department.
