Building for Salt Lake City homes
Salt Lake City is one of Utah's oldest and most established communities, and its housing reflects that — brick bungalows in Sugar House, historic homes in The Avenues, mid-century houses in Rose Park and Glendale, and newer infill near downtown. Many of these homes sit on lots that can support a thoughtful addition or an accessory dwelling unit, and a large share have full basements that are excellent candidates for finishing. CasaMás Construction helps Salt Lake City homeowners add living space, rental potential, and equity without moving — whether that means finishing a basement in a 1940s home, adding a primary suite, or building an ADU for family or rental income when allowed by local city rules. Every project is built to code, and we work in both English and Spanish from the first consultation to the final walkthrough.
The projects that make the most sense for Salt Lake City homes:
Local knowledge, every neighborhood
From the foothills of the Avenues to the west-side neighborhoods around Rose Park and Glendale, Salt Lake City homes vary widely in age, foundation type, and lot size — which is exactly why we start every project with a free, on-site look before we quote. Ask us for recent local examples during your estimate.
Permits & local rules in Salt Lake City
Most additions, basement conversions, and ADUs in Salt Lake City require permits through the city's building and planning departments, and some neighborhoods fall within local historic districts that add design review. Salt Lake City has expanded its accessory dwelling unit options in recent years, but local rules change — we work from the city's current requirements and handle the permitting as part of your project. Any rental use is possible only when it meets local city rules.
Financing options may be available, subject to approval. Monthly payment examples are estimates.
Frequently asked questions
Do you build ADUs in Salt Lake City?
Yes. We build attached, detached, basement, and garage-conversion ADUs for Salt Lake City homeowners — for family use or rental income potential when allowed by local city rules. We review your lot and the city’s current requirements during a free estimate.
Can you finish the basement in an older Salt Lake City home?
Absolutely — older homes are some of our favorite basements to finish. We address moisture, egress windows, ceiling height, and current code so the finished space is comfortable, safe, and permitted.
Do you work in historic districts like The Avenues?
Yes. Homes in Salt Lake City’s local historic districts can involve extra design review; we plan for that up front so your addition or remodel respects the home and meets the city’s requirements.
Do you serve Salt Lake City homeowners in Spanish?
Sí. We serve Salt Lake City homeowners in both English and Spanish, from the first consultation through the final walkthrough.
