Garage Conversion Cost: What You Will Actually Pay in 2026
A garage conversion in 2026 most often costs $9,659 to $51,659. The average project runs around $30,659. The full range is wider than that. A bare-bones room can cost about $4,000. A full living unit with its own kitchen and bathroom can cost $73,200. The price depends on your scope. Utah's egress window rule adds a real cost most quotes miss.
Below is what drives that range and what Utah's permit and window rules mean for your budget.
How Much Does a Garage Conversion Cost in 2026?
Most 2026 garage conversions cost between $9,659 and $51,659. The average lands around $30,659. Your real number depends on the scope. It can run lower or higher than that typical band:
- Basic conversion: $4,000 to $12,000. Insulation, drywall, flooring, simple electrical, and a minimal window. No new plumbing.
- Mid-range conversion: $12,000 to $25,000. Upgraded insulation, better flooring, added plumbing, real windows, and an HVAC extension from the main house.
- High-end conversion: $25,000 to $40,000. Structural changes, higher-end finishes, and custom details.
- Full ADU or studio: $31,500 to $73,200. A complete living space with its own separate utilities, kitchen, and bathroom.

Is It Cheaper to Convert a Garage or Build a New Addition?
Converting a garage usually costs less per square foot than building new. A conversion already has a roof, a foundation, and walls. A new addition needs new footings, new framing, and a new roof tie-in from scratch. That adds cost before you even start on finishes. If your garage sits where you need the space anyway, converting it skips the most expensive parts of building new. See our addition and garage conversion service for how we scope both options.
What Drives the Price: Electrical, Plumbing, and HVAC
Three systems explain most of the price swing between a basic conversion and a full ADU.
Electrical work is almost always a big part of the budget. It typically runs $615 to $4,021. A garage usually has one circuit, for the door opener, and maybe one outlet. Turning it into a bedroom, office, or living room means new circuits and outlets. It often needs a new subpanel too.
Plumbing runs $1,500 to $4,000 when you add it. This only applies if you add a bathroom or a small kitchen. That pushes the project toward the ADU tier.
HVAC extension costs $300 to $5,000. A garage is not heated or cooled like the rest of the house. Tying it into your existing system, or adding a mini-split, is its own line item.
Do You Need a Permit and an Egress Window in Utah?
Yes. Utah uses the 2021 International Residential Code statewide. South Jordan reviews plans against this same code. Any sleeping room needs an escape window. So does every basement. Most people call this an egress window. The code sets real numbers. The window opening must be at least 5.7 square feet below grade. At grade level, it can be 5 square feet. It needs a width of 20 inches. It needs a height of 24 inches. The sill can sit no higher than 44 inches above the floor.
This matters because a garage was never built with a code-size window. If you want the space to work as a bedroom, you will likely need to cut a new, larger opening into the wall. That is a real cost most online calculators skip.
Local permit rules back this up too. Eagle Mountain's own Building Department names garage-to-living conversions as a project that needs a permit. It sits in the same group as finishing a basement or changing a load-bearing wall. South Jordan reviews addition and conversion plans under this same code. Skipping the permit is risky. An unpermitted conversion can cause problems at resale. An appraiser checks square footage against city records.
We handle the whole process on every addition project. That includes pulling the permit and scheduling inspections, so you do not have to deal with the city yourself.
Is a Garage Conversion Worth It on a Bigger Eagle Mountain or Bluffdale Lot?
It often makes more sense on a bigger lot than on a standard tract lot. In Eagle Mountain, most homes sit on bigger lots outside the city center, with detached garages and shops. Converting one does not force a hard tradeoff with parking, the way it can on a smaller lot. Bluffdale mixes older rural-era properties with newer subdivisions on some of the biggest lots in the area. That is where a full ADU conversion, the $31,500 to $73,200 tier, is most likely to pay off, either as a rental or as extra space for family.
On a smaller South Jordan lot, where the garage is your only covered parking, weigh that tradeoff first. A basic or mid-range conversion may fit better if parking matters more than extra square footage.

FAQ

Does a garage conversion lower my home's value?
It depends on the neighborhood and whether the work is permitted. A permitted conversion that adds real, finished living space usually helps value. Losing covered parking can matter to some buyers, so it is worth thinking about how your street uses garages before you convert.
What is the cheapest way to convert a garage?
A basic conversion without new plumbing costs the least, usually $4,000 to $12,000 as of 2026. That covers insulation, drywall, flooring, simple electrical, and a minimal window. Skipping plumbing and HVAC upgrades keeps the price down.
Can a converted garage become a rentable ADU?
Yes. A full accessory dwelling unit conversion with its own kitchen, bathroom, and separate utilities runs $31,500 to $73,200 as of 2026. That is the highest tier because it needs its own systems, not shared ones with the main house.
