Cost to Second Story Addition in Salt Lake City, UT (2026)
If you’re budgeting a second story addition in Salt Lake City, most projects run $96,387-$289,160, 4% below the $175,000 national average. What moves that number most is usually one thing: Foundation and First-Floor Capacity. On its own it can swing the cost by $10,000 - $60,000, so that’s the decision to slow down on before you sweat the smaller stuff.
Easiest place to save: Commission a structural engineering report ($500-$1,500) before finalizing your budget. Foundation issues discovered mid-project are far more expensive than catching them upfront.
