Many Los Angeles homeowners have a garage that no longer serves much purpose. It can contain old boxes and tools as the car remains parked in the driveway. When rents are high and families require more space, making that space into a small home seems like a good idea.
However, the selection of a builder is not quite easy. There are many ADU companies offering quality, speed, and reasonable pricing in Los Angeles. It’s difficult to determine which is the right one for your garage, budget, and timeline.
If you know what to look for, you can choose the right builder. A suitable garage conversion builder has practical experience with such conversions, is able to deal with the permits, and clarifies the price clearly. It is much easier to compare companies on these aspects.
In this guide, we compare five ADU companies in Los Angeles, so you can pick and choose with confidence.
1. GOADU
Go ADU Construction is a Burbank-based company that builds only ADUs, which makes it one of the best ADU builders in Los Angeles to consider for a garage conversion. It offers design-build services and lets homeowners compare attached ADU layouts, detached ADUs, and garage conversion designs, so you can see your options before you decide.
Its team also manages each permit from start to finish, so design, permits, and construction sit with one team and you are not juggling several professionals.
That can be a relief if this is your first ADU. You have one place to bring questions, and it is easier to see how each choice affects cost and schedule.
Garage projects often turn up small surprises, like an old slab or an outdated electrical panel. A team that designs and builds together can adjust the plan quickly when they appear.
- Specialty: Design-build garage conversions
- Best for: Homeowners who want a single point of contact from planning to final inspection
2. ADU Build Los Angeles
Where GOADU highlights a single team, ADU Build Los Angeles points to volume, saying it has completed more than 200 ADUs. That kind of history often means a team has dealt with common garage issues, like old concrete slabs, tight setbacks, and hard-to-reach utility lines.
Experience can also help during city plan review. Builders who submit plans often know what reviewers look for, which may cut down on delays.
To get the most from that track record, find out how many of those projects were garage conversions, and look at photos of similar work.
Schedule is another useful detail. Because the structure is already standing, a garage conversion often moves faster than a new build, so a realistic timeline from design to final inspection is worth requesting.
- Specialty: Full-service ADU construction
- Best for: Homeowners who value a long track record
3. ADU Los Angeles
Next is ADU Los Angeles, a local company that focuses on accessory dwelling units. A company that works only on ADUs is usually familiar with how city rules apply to garages, such as yard requirements and utility easements.
Get a written scope from each company that lists everything the price includes. A common example is an electrical panel upgrade, which many older homes need before adding a new living space.
Quotes from a few local companies make this easier to judge. When each one lists the same items, the differences stand out.
Local experience can also help with practical planning. A company that works on many Los Angeles properties may spot access, parking, and utility issues early, which keeps the budget closer to the first estimate.
- Specialty: Local ADU construction
- Best for: Homeowners who want an ADU-only company and plan to gather several quotes
4. Ataman Studio
Ataman Studio, a Los Angeles architecture and design-build firm, puts design first and works on custom homes, ADUs, and remodels. Its ADU design work covers detached ADUs, garage conversions, and junior ADUs. It also offers 3D renderings.
Seeing a 3D view lets you picture the finished space before any building starts. That helps when your garage has an awkward shape or you want a more custom look, and fewer changes during construction can mean fewer surprises.
Its design focus may suit you if you are planning a bigger remodel alongside the ADU. One firm handling both can keep the main home and the new unit looking consistent.
Permit-ready plans are part of the package too. The firm prepares them and coordinates the permitting process, which keeps design and paperwork lined up.
- Specialty: Design-led ADU projects
- Best for: Homeowners who want to see and adjust the layout first
5. Abodu
Abodu takes a different route from the garage-focused builders above. It builds modular backyard homes and ADUs with fixed, all-in pricing, which makes it a strong option for new construction.
Think of it as a comparison point. If your garage is too small, in poor shape, or needed for parking, a factory-built unit may be a better fit, and costs can be easier to predict.
A backyard unit also keeps your garage free for storage or vehicles, so think about how much yard space you want to use.
Weighing the two paths is easier with a shared checklist. List the price, timeline, and inclusions for each option, then see which one fits your lot and budget.

Is Converting a Garage into an ADU Worth It?
Yes, for many homeowners, though it depends on your goals and your property. A conversion reuses the existing foundation, walls, and roof, so it usually costs less than building a new unit from the ground up.
One 2026 local overview estimates garage conversions in Los Angeles at roughly $90,000 to $160,000. The final price depends on the garage’s condition, how far plumbing and electrical lines must run, and the finishes you choose.
Money is not the only payoff. A finished unit can bring in rental income, house a family member, or serve as a home office or guest space.
Long-term plans matter as well. If you may want the space for family later, a conversion can work as a rental now and a guest suite or home office down the road.
Before you commit, weigh the tradeoffs. You give up the garage for storage and possibly parking, and some lots have limits under state and local ADU rules. A short property review by a builder or designer can tell you early whether your garage is a good candidate.
Bottom Line
Every garage is different, so the best builder depends on your goals, budget, and property. GOADU suits homeowners who want a single team to manage a conversion from start to finish. ADU Build Los Angeles and ADU Los Angeles bring ADU-focused experience, while Ataman Studio leans toward design.
Modular homes like Abodu’s are a good alternative when a garage is not the right fit. Whichever you choose, verify the contractor’s license, ask to see similar past projects, and get written quotes from at least three companies.
Take your time, ask plenty of questions, and let the quotes guide your decision.
