Adding an ADU to a Palms property usually means working with a lot that is 50 feet wide, a bungalow that is 80 to 100 years old, and a rear garage that sits farther from the curb than most people expect. We build detached ADUs, garage conversions, and studio units in Palms every month, and we know what these lots do to a foundation and an electrical panel. If you want a written price before any work starts, call (213) 732-1415. Reed Calloway runs our field operations, and he will walk your lot with you before anything gets quoted.
Why Fielding ADU Los Angeles Is Palms’s Preferred ADU Builders Company
Most Palms homeowners have already talked to at least one contractor before they call us. They heard a low number, then watched the price climb when the permit office got involved. That is exactly the problem our written-price policy exists to solve. The number you approve before framing is the number on the final invoice, unless you request a change. Palms lots are small, flat, and full of 1920s-to-1940s construction quirks. We have opened enough walls on Motor Avenue, Overland Avenue, and the streets around Palms Park to know what the building department will flag and what the original framing will actually carry. Our crews are background-checked and arrive in uniform. You know who is on your property from the first day.
Fielding ADU Builders operates inside the Garrison Partners family. Garrison has built to The Garrison Standard since 2006, and that standard is simple enough to fit in a sentence: show up in the window, price in writing, build by the book, leave it clean, stand behind it for a year. We call it The Garrison Code. It is not marketing language. It is what our contract says.
ADU Contractor in Palms
An ADU Contractor in Palms is the general contractor who carries the permit, schedules the inspections, and is responsible for every trade on the job. When you hire us, you get one point of contact from the first site walk to the final inspection sign-off. On a typical Palms detached garage conversion, the ADU Contractor’s scope includes demolition of the old roof and slab edge, foundation work, framing, roofing, electrical, plumbing, drywall, insulation, and exterior siding. We coordinate all of it. We also handle the paperwork with the Los Angeles Department of Building and Safety, which for Palms means dealing with the city’s ADU size limits and rear setback rules. A garage conversion in Palms typically runs $140,000 to $220,000 before permit fees, depending on whether we are keeping the existing shell or replacing it. A new detached ADU from the ground up usually falls between $220,000 and $350,000. Prefab and modular units from Abodu or Cover tend to land in the $180,000 to $300,000 range once site work, foundation, and utility connections are included. Those are honest ranges, not a teaser number.
Permit Scope and Paperwork
Palms falls under the city of Los Angeles, which means the ADU rules are the state’s, and they are more permissive than most people expect. We still verify lot coverage, rear and side setbacks, and height limits before we quote. If your neighbor’s detached garage sits two feet from your vision for an ADU, we check the setback variance rules before you spend anything.
Garage Conversion Reality Check
Most Palms garage conversions look simple from the outside. The garage already has four walls and a roof, so the logic goes that the job is mostly drywall and a bathroom. In our experience, the opposite is true. Once we open the walls, we find what the original 1940s builder left behind. That is where the real cost lives.
ADU Design in Palms
ADU Design in Palms has to solve one problem better than anything else: how to put a livable, rentable, comfortable unit on a lot that was never meant to hold two homes. The front bungalow is usually Spanish Colonial Revival, Craftsman, or Minimal Traditional, one story, with a long driveway running down one side to a detached garage at the rear. The best ADUs in Palms are the ones you cannot see from the street. That means working with the existing garage footprint, keeping the roofline low, and matching the exterior finish to the house. James Hardie siding in a color that reads as stucco or wood from the curb is one way we do it. A design that hides the unit behind the original garage position is another.
Working With the Bungalow, Not Against It
We do not fight the lot. We design ADUs that keep the existing garage’s setback, use the long driveway for access, and keep the street-facing elevation quiet. On many Palms blocks, the original garage is set back so far from the street that a detached ADU above or behind it is effectively invisible from the curb, letting homeowners add a rental unit without altering the neighborhood’s low-rise bungalow character. That is the single best design move available in this neighborhood, and we plan for it from the first sketch.
Prefab and Modular Options
Some Palms lots are too tight for conventional stick-framing without eating the whole rear yard. When that is the case, we bring in prefab and modular platforms: Abodu, Cover, and Dvele are the three we use most on Palms lots. The unit arrives as a panelized or volumetric build, and our crew handles the foundation, utilities, and finish work. The design advantages are tighter tolerances and a faster dry-in, which matters on a lot where you are already losing half your yard to the build.
Trusted Brands We Service in Palms
We install and finish ADUs from Abodu, Cover, and Dvele, and we build conventional units with James Hardie siding as the exterior standard. We also work with Tuff Shed-style structures for storage-to-ADU conversions where the shell is sound. Because we handle Palms jobs regularly, we keep local vendor relationships for windows, roofing, and electrical rough-in materials, which means fewer supply delays on a schedule you already waited too long to start. For a lot in Palms, the right build method is the one that fits your budget and your setback. We help you choose honestly.
Common ADU Builders Problems We See in Palms Homes
- Undersized electrical service. Many 1920s and 1930s Palms homes still have a 60-amp or 100-amp panel. An ADU with a range, a water heater, and a mini-split will not run on that. We pull the permit for the panel upgrade and write the allowance into the contract before framing starts.
- Wet or heaving garage slabs. The original detached garages in Palms were built for cars, not people. Most slabs have no moisture barrier, and some have cracked or shifted over 70 to 100 years. We test, and if the slab is failing, the fix is a new stem-wall foundation with a vapor barrier. That is a line item, not a surprise.
- Knob-and-tube wiring and ungrounded circuits. Opening a 1940s garage wall often reveals original cloth-wrapped wiring. Los Angeles building code will not let you hang drywall over that. We scope the rewire during pre-construction, so it is in the price, not discovered mid-job.
- Seismic and shear requirements. Palms is in a seismic zone, and adding square footage triggers lateral bracing and shear wall requirements. The city’s plan checker will flag it. We design for it from day one, because fighting it after the fact doubles the cost.
On a 1940s Minimal Traditional bungalow in Palms, our crew opened the detached garage to convert it and found original knob-and-tube wiring and a slab with no moisture barrier. We scoped the permit-triggered upgrades, wrote a fixed allowance for panel replacement and vapor barrier into the contract, and only after the owner approved the change order did we rewire and pour the new stem-wall foundation before framing the ADU above. That is how the process should work, and it is the only way we build.

FAQs About ADU Builders in Palms
Once the drywall or plaster comes off in a 1920s Palms bungalow, the city’s building code applies to what we find underneath. That usually means replacing knob-and-tube wiring with modern Romex, adding shear wall panels to meet seismic requirements, and bringing the panel up to at least 100 amps, often 200. Those upgrades go into our written allowance before we open the first wall. Call (213) 732-1415 for an exact scope and price on your house.
The simplest answer is a rear detached ADU built above or behind the original garage position. On many Palms lots, the garage is set so far back from the curb that the unit is invisible from the street. We keep the roofline low, match the siding to the front house, and the neighborhood character stays intact. That is the most common design strategy we use in Palms.
Because the original garage was built for a car, not a bedroom. The slab usually has no vapor barrier, the walls have no insulation, the roof framing is undersized for ceiling insulation and drywall, and the wiring is often original knob-and-tube. All of those need upgrades before the building inspector will sign off. Our written price accounts for them, so you are not paying for them as surprises.
We stop, document what we found, and price the repair as a change order before we touch anything else. You approve it in writing or we do not proceed. That is the Garrison Code. The contract gives us a process for discovery, so a bad stud or a failed weather barrier does not turn into an argument.
Yes, and in Palms it is one of the best setups you can have. The long driveway already gives you legal access to the rear unit, and the garage’s setback keeps the ADU off the street-facing elevation. The main constraints are the garage’s structural condition and whether the existing footprint leaves enough room for setbacks. We measure, check the title, and tell you what is buildable before you commit.
If you are ready to get a written price for an ADU in Palms, call (213) 732-1415. Reed Calloway and our team will walk the lot, check the garage, the panel, the slab, and the setbacks, and hand you a line-item price. The Garrison Standard covers workmanship defects for 365 days after completion. If something fails, we come back and make it right at no charge. That is the promise, in writing, for every Palms project we build.
