A garage conversion in Coachella typically costs between $85,000 and $145,000 for a finished ADU with a kitchen and bath, and $45,000 to $75,000 for a simpler living-space conversion without plumbing. Those ranges include the Coachella-specific work most bids leave out: valley-grade insulation, a new vapor barrier under the slab or over it, reframing the garage-door wall, and correctly sized HVAC for summers that run past 110°F.

Why Fielding ADU Builders Is Coachella’s Preferred Garage Conversion Contractor Company

We’re part of Garrison Partners, which has been building to The Garrison Standard since 2006. That standard is simple: show up in the window, put the price in writing before a single nail is driven, pull permits by the book, leave the site clean, and stand behind the work for a full year in writing.
Coachella homeowners call us after someone else already burned them. Maybe a contractor quoted by square footage and then “discovered” the slab needed work the city would flag. Maybe a crew vanished at the halfway mark. Reed Calloway, who leads Fielding ADU Builders, structured the company so those conversations don’t happen here. The number you approve on day one is the number on the final invoice. If the work fails inside 365 days, we return and correct it at no charge. That’s not a promise. It’s the written guarantee every customer receives.
Every crew member on a Coachella job is background-checked and uniformed. You know who’s on your property. And when you call (361) 315-4177, a live person answers. Noon or midnight.
Garage Conversion ADU in Coachella
A Garage Conversion ADU in Coachella means taking an existing attached or detached garage shell and turning it into a fully permitted accessory dwelling unit with its own kitchen, bath, sleeping area, and separate entrance. The price for a completed ADU here runs $85,000 to $145,000, and the reason it’s not cheaper is specific to this valley. A garage in Coachella was never conditioned space. The slab usually sits directly on ground with no vapor barrier, the walls have no insulation, and the roof bakes hard every afternoon. Converting that shell into livable, rentable space means fixing the shell first, not hiding it behind drywall.
This is the page’s whole point, and it’s why our quoting process for Coachella jobs starts at the slab and works outward. A contractor who quotes you $45,000 for a full ADU here is either lying, skipping the permit, or planning to hit you with change orders the week framing starts. The city plan check will catch most shortcuts. The Coachella Valley energy documentation and HVAC load calculations are not optional paperwork. Skip them and the plan check stalls. Your price reopens mid-job.
Attached Garage Conversion
An attached garage shares a wall with the main house, so the conversion ties into existing utilities and roofline. That can cut cost versus a detached build, but it also means the finished unit shares a thermal envelope with a house that was never sized to cool extra square footage. We typically run a dedicated mini-split for converted attached garages rather than forcing the main unit to carry the load across a poorly ducted branch line.
Detached Garage Conversion
A detached garage in Coachella usually sits at the back of the lot on Avenue 50 or off a side street near the Dateland Park area, with buried or overhead service drops that were never sized for a dwelling unit. Bringing power, water, and sewer from the main house to a detached structure adds real cost. We price that trenching, panel upsizing, and any setback variance the city requires before you sign anything.
Garage Apartment Conversion in Coachella

A Garage Apartment Conversion in Coachella is a specific form of ADU: the garage becomes a separate rental unit with its own address, separate meter or sub-meter, and a layout that works as a long-term residence rather than a spare room. These projects run $95,000 to $145,000 here, and the range depends mostly on how much of the existing shell can be legitimately reused under current Coachella building and energy codes.
On a cul-de-sac off Calle Empalme near the Dateland Park side of town, we converted a two-car attached garage into a 420 sq ft garage apartment for a homeowner whose adult son was moving back in. The existing slab had no vapor barrier and the south-facing garage door wall baked all afternoon, so we framed and insulated new interior walls, used James Hardie siding on the reframed front wall where the old door was removed, and ran a dedicated mini-split rather than tying into the undersized house unit. Six weeks after framing inspection we handed over a permitted, separately metered unit.
Separate Metering and Rental Rules
If the converted unit will be a true rental, the city requires separate metering or sub-metering in most cases, plus a dedicated water heater and its own panel. That’s not a hidden fee. It’s a code requirement we line-item in your written price before work starts.
Garage to Bedroom vs. Garage Apartment
A garage-to-bedroom conversion without a kitchen or separate entrance costs less and moves faster because it’s a remodel, not a new dwelling unit. But if you want the space to generate rent down the line, build it as a garage apartment from the start. Retrofitting plumbing and separate metering later costs more than doing it once correctly.
Trusted Brands We Service in Coachella
We work with the major prefab and modular ADU platforms Coachella homeowners are already researching: Dvele, Mighty Buildings, and Boxabl. We also build conventional structures with James Hardie siding and Tuff Shed-style shells where the budget or lot calls for it. That fluency matters because a prefab unit drops onto a different foundation detail than a stick-built conversion, and the city’s plan check treats them differently too. We stock common components for the brands above and can typically source Coachella-specific materials without the long lead times that stall some valley projects.
Common Garage Conversion Contractor Problems We See in Coachella Homes
- Slab without a vapor barrier. Most Coachella garages were poured as parking pads on grade. Cut the slab open and the soil beneath breathes moisture straight up through the concrete every humid monsoon season. We add a vapor barrier and often re-pour sections of slab before any framing goes on top.
- Old garage-door header undersized for the new wall. The header that carried the roll-up door was never engineered to hold a wall with windows, insulation, and stucco. We reframe that opening properly and pull the engineering the city wants to see.
- Attic space with zero insulation and no ventilation. A Coachella summer turns an uninsulated attic into a heat bank that radiates down into the new living space all night. We insulate to valley-grade requirements and fix the venting before drywall goes up.
- HVAC sized for the original house, not the added unit. The existing condenser was sized for the square footage the builder planned, not the extra 400 sq ft you’re adding. We run dedicated equipment or correctly upsize, and we document the load calc the Coachella Valley plan check requires.

FAQs About Garage Conversion Contractor in Coachella
Yes. A garage conversion in Coachella that creates living space with a kitchen or bath requires a building permit, and converting it to a rentable ADU also triggers the city’s energy documentation, duct and HVAC load calcs, and possibly a setback variance review. We pull every permit, schedule every inspection, and you see the permit card posted before framing starts. Call (361) 315-4177 and we’ll walk you through what your specific garage triggers.
Plan on four to seven months from the day we submit drawings to the day the final inspection passes. The Coachella plan check for an ADU typically runs three to six weeks, and if the garage needs slab repair or a new vapor barrier, add two to three weeks before framing begins. We give you a written calendar with the written price, and we hold to it.
The shell. A Coachella garage was built to park cars, not to house people. The slab usually lacks a vapor barrier, the walls are uninsulated, the garage-door header is undersized, and the existing HVAC was never sized for the added square footage. Fixing those four items is often $15,000 to $30,000 before any finish work starts. Our written quote line-items each one so you see exactly where the money goes.
Yes, if you build it as a garage apartment conversion with its own entrance, kitchen, bath, and separate or sub-metered utilities. Coachella allows attached and detached ADUs for rental use, and a separately metered unit is what most owners want when the goal is long-term income. We handle the meter separation, the water heater sizing, and the energy documentation as part of the written price.
Nothing, if the price was written honestly. The only legitimate change orders we see on Coachella jobs come from conditions no one could see before cutting in: a sewer line that’s collapsed under the slab, a panel that fails inspection, or soil that tests worse than expected. We line-item those as they come, show you the written change order before any money is spent, and you approve it first. The original bid never changes because the garage was “worse than expected” after we already walked it.
