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

We’re the Garage Conversion Contractor team inside Fielding ADU Builders, an independently owned member of the Garrison Partners family. That matters to Palm Desert homeowners because The Garrison Standard has been the operating rule since 2006: show up in the window promised, put the price in writing, pull permits by the book, leave the site clean, and stand behind the work for a full year in writing.
Reed Calloway leads our crews. He’s built garage conversions across the Coachella Valley and knows how Palm Desert’s permit desk reviews change-of-occupancy work. That local familiarity means fewer plan-check rejections and a cleaner path from bid to building permit.
Every crew member is background-checked and arrives in uniform. You’ll know exactly who’s on your property on Washington Street or Portola Avenue. And when you call, a live person picks up. 24 hours a day. No voicemail tree.
The 365-Day Done Right Promise covers workmanship defects for one full year. If something fails, we come back to Palm Desert and fix it at no charge. That guarantee is written on paper, not implied. Most contractors in the valley won’t put that sentence in a contract.
Garage Conversion ADU in Palm Desert
Garage Conversion ADU in Palm Desert means taking attached or detached garage square footage and turning it into a legal accessory dwelling unit with its own entrance, kitchen, bathroom, and sleeping area. Under California state law, Palm Desert must approve ADUs that meet building code, and the city treats a garage conversion as a change of occupancy, not a simple remodel. That distinction triggers Title 24 energy calculations before framing starts.
In Palm Desert, expect to pay $95,000 – $160,000 for a garage conversion ADU with a full kitchen and bath. Budget another $8,000 – $15,000 for permit fees, Title 24 documentation, and school district impact fees, which vary by square footage. The exact number depends on whether your garage has a vapor barrier under the slab, whether the existing header carries the roof load, and how much HVAC capacity the new living space needs.
Attached Garage ADU Conversions
An attached conversion works best in Palm Desert neighborhoods where lot coverage rules already favor larger footprints, like tracts along Cook Street or Gerald Ford Drive. The garage shares utilities with the main house, so sewer and electrical runs stay short. The tradeoff is that the existing slab often lacks a vapor barrier, which means a new 4-inch pour before framing. Plan for it.
Detached Garage ADU Conversions
A detached garage gives you more privacy, which Palm Desert homeowners in communities off Deep Canyon or Highway 111 tend to value for rental units. You’ll run new sewer, water, and electrical laterals, and the city will want a separate address for the ADU. Expect project costs on the higher end of the range due to trenching and utility connections.
Garage Apartment Conversion in Palm Desert

Garage Apartment Conversion in Palm Desert converts the garage into a rentable or family apartment, often without the full ADU classification but still requiring change-of-occupancy review. The city’s permitting path is nearly identical to an ADU conversion; what differs is how you finish it. A garage apartment conversion here typically costs $75,000 – $120,000, depending on whether you’re adding a full kitchen or a kitchenette with a wet bar.
Palm Desert homeowners in the Palmeras and Silver Spur Ranch areas use apartment conversions for seasonal rentals, which the city regulates through short-term rental permits. If that’s your plan, mention it during the walkthrough. The permit requirements change slightly, and we’d rather flag it now than surprise you at plan check.
Garage to Bedroom and Living Space
A garage-to-bedroom conversion without plumbing runs $45,000 – $75,000 in Palm Desert. The work is mostly framing, insulation, drywall, flooring, and HVAC. Without a wet bar or bathroom, the scope stays simpler and the permit moves faster. But the Title 24 energy requirement still applies. Heat is structural here, whether or not you’re adding water lines.
Garage to Full Apartment with Kitchen
Adding a kitchen changes the scope meaningfully. You’ll need new plumbing, gas or electric appliance circuits, and a range hood that exhausts to the exterior. In Palm Desert, the city’s inspection list includes ventilation and grease capture, even for accessory units. Budget $100,000 and up when a full kitchen is part of the plan.
Trusted Brands We Service in Palm Desert
We work with homeowners who want a conventional build and with those researching factory-built options. For Palm Desert garage conversions, we regularly configure units from Cover, Dvele, and Boxabl, matching panelized construction to lots where access is tight. We also build conventionally using James Hardie siding, which holds up well against desert sun and wind-driven sand along the valley floor. If you’re weighing a Tuff Shed-style base structure against a fully custom ADU, we’ll price both so you can compare on paper. Parts and finish materials for these brands are sourced regionally, so we aren’t waiting on slow supply chains when a change order comes up mid-project.
Common Garage Conversion Contractor Problems We See in Palm Desert Homes
- Title 24 rejection at plan check. Skipping the energy calculation because the garage feels enclosed costs 2 – 3 weeks in permit delay. Palm Desert’s plan-check desk flags this on nearly every conversion that comes in without it.
- No vapor barrier under the existing slab. Palm Desert’s soil holds moisture that wicks up through bare concrete. Without a barrier, flooring fails within a year and you’re tearing out work we already closed up.
- HVAC sized like a standard interior room. A garage that hits 130°F in July needs a dedicated system. If the load calc treats it like a bedroom, the space is unusable from June through September.
- Undersized garage door headers. Many Palm Desert homes from the 1980s and 1990s have headers that barely carried the original door. When that opening gets framed into a wall, the header needs to be replaced or reinforced. We catch this at the walkthrough, not after demo.
Pricing for Garage Conversion Contractor in Palm Desert, CA

FAQs About Garage Conversion Contractor in Palm Desert
Yes. Palm Desert treats garage conversions as a change of occupancy, which means a building permit, Title 24 energy calculations, and inspections are required before, during, and after the work. Unpermitted conversions create problems at resale and can trigger code enforcement if a neighbor files a complaint. Call (361) 315-4177 to have us handle the permit package from day one.
Most garage conversion ADUs in Palm Desert take 10 – 16 weeks. Plan-check at the city typically runs 3 – 5 weeks. Framing, mechanical, and finish work takes another 6 – 10 weeks depending on scope. The fastest path is having Title 24 documentation ready before the first submittal, which we prepare as part of the estimate.
The three biggest cost drivers are slab replacement, HVAC sizing, and sewer lateral work. A missing vapor barrier forces a new slab pour. Palm Desert’s summer heat means you need a dedicated system sized for attic-like temperatures. And any kitchen or bath means opening the slab for plumbing lines. Call (361) 315-4177 and we’ll walk the garage with you and put the real numbers in writing.
No. A legal ADU conversion requires removing the garage door and framing that opening as a permanent wall with a proper header. Some Palm Desert homeowners in HOAs have asked about keeping the door for aesthetic reasons, but the city will not sign off on an occupancy change with a functioning garage door in place.
We remove the old slab, pour a new 4-inch slab with a vapor barrier, and continue from there. In the Sun City Palm Desert community off Washington Street, our crew found exactly this condition on a 400 sq ft attached garage conversion. We poured a new slab, replaced an undersized header with a 4×12 beam, upsized the HVAC to a 1.5-ton mini-split, and added Title 24-compliant insulation. The final inspection passed and the ADU has been comfortable through two full summers.
If you’re ready to turn that unused garage into real living space, call (361) 315-4177. Reed Calloway will walk the property with you, explain exactly what the city will require, and hand you a written price. No pressure. No vague estimates. Just a number you can hold us to.
