Cost to Garage Conversion in Salt Lake City, UT (2026)
If you’re budgeting a garage conversion in Salt Lake City, most projects run $9,429-$28,286, 6% below the $20,000 national average. What moves that number most is usually one thing: HVAC - Mini-Split vs. Duct Extension. On its own it can swing the cost by $2,000-$5,000 for mini-split; $1,500-$3,500 to extend existing ductwork, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Skip the full bathroom if you don't need rental income - adding plumbing adds $5,000-$12,000 to the project. A powder room (half bath) is a good middle ground at $3,000-$6,000.
In the Mountain West (where Salt Lake City sits): Higher costs in resort and metro markets; extreme temperature swings demand better HVAC.
