Detached Garage Conversion in Los Angeles, CA
A detached garage conversion in Los Angeles turns a freestanding garage into a fully permitted living space with its own kitchen, bathroom, and separate entrance, and it typically costs $180,000 to $320,000 depending on the garage’s condition, foundation type, and whether you add square footage. Most detached conversions in LA take 6 to 10 months from design to final inspection. If you’re sitting on an unused two-car garage in neighborhoods like Silver Lake, Van Nuys, or West Adams, converting it is often the fastest way to add rentable or multigenerational living space without giving up your backyard.
Lodgewick ADU Los Angeles specializes in exactly this kind of project. We’re part of the Kingswell family of home service companies, founded in 2010, and every detached garage conversion we take on runs under Garage Conversion ADU in Los Angeles standards: written price before work starts, a defined arrival window, a job site we clean daily, and a written guarantee on the finished build. Call (213) 698-7116 and a live person answers, any hour, any day.

When You Need Detached Garage Conversion
Not every garage is worth converting, and not every homeowner needs to. Here’s what pushes most Los Angeles homeowners over the line:
- The garage hasn’t held a car in years. If it’s become a storage locker for holiday decorations and old furniture, converting it to a rental unit or a home office puts the square footage back to work.
- You need space for aging parents. A detached ADU gives parents their own front door, their own kitchen, and walkable proximity to family without sharing walls. In neighborhoods like Eagle Rock and Highland Park, we see this scenario constantly.
- You want rental income without moving. A converted detached garage in central LA rents for $1,800 to $2,800 per month depending on size and finish level. That’s real money against a Los Angeles mortgage.
- The garage is structurally sound but cosmetically tired. Good bones mean lower conversion cost. If the slab is level, the walls are square, and the roof doesn’t leak, you’re ahead of the game before we start.
- You already have alley access or a wide side yard. Detached garages with separate access make ideal ADUs because the tenant or family member never walks through your living room. Many LA lots built before 1960 have exactly this layout.
- You’ve been burned by a contractor before. If a past project went sideways on price or schedule, you need a company that puts every commitment in writing. That’s the entire reason The Kingswell Guarantee exists.
Our Detached Garage Conversion Process
Here’s what working with Lodgewick ADU Los Angeles looks like from the first call to the final walkthrough:
- Phone consultation and site visit. You call (213) 698-7116, speak to a real person, and we schedule a walkthrough of your detached garage. Russ Delmar or a senior project lead visits the property to assess foundation condition, roofline, existing electrical, and access for construction vehicles.
- Written price and scope. Before any work starts, you get a written price and a detailed scope of work. No vague allowances, no “we’ll figure it out later.” The number we hand you is the number the job costs, period.
- Design and permitting. We handle Los Angeles Department of Building and Safety submittals, including any required setback reviews and utility upgrades. Detached garages in LA often need new electrical service and sometimes a sewer line extension, and we account for all of it in the written scope.
- Construction and daily job site care. Our background-checked, uniformed crew shows up in the window we gave you. We keep the site clean at the end of every day, communicate progress by phone or text, and keep your neighbors informed when work impacts shared driveways or alleys.
- Written guarantee and final walkthrough. Every project ends with a written guarantee delivered to you, backed by the 365-Day Done Right Promise. If something isn’t right within a year, we come back and fix it, free of charge.

Detached Garage Conversion Pricing in Los Angeles
Detached garage conversion in Los Angeles typically runs $180,000 to $320,000 all-in, including design, permitting, construction, and finish work. Smaller single-car garages with simple layouts can come in around $150,000. Larger two-car garages with full kitchens, custom tile, and high-end finishes can push past $350,000. Here’s how the numbers break down:
| Item | Typical Range |
|---|---|
| Full conversion of a single-car detached garage (approx. 250 sq ft) | $150,000 – $200,000 |
| Full conversion of a two-car detached garage (approx. 400 – 500 sq ft) | $200,000 – $320,000 |
| Foundation work (sister footings, slab leveling, seismic anchors) | $8,000 – $25,000 |
| New electrical service and panel if garage is on a separate meter | $6,000 – $18,000 |
| Kitchen and bathroom package (mid-range finishes) | $35,000 – $65,000 |
| Permitting and design fees | $12,000 – $25,000 |
What moves the number most? Foundation condition is the big one. Detached garages in Los Angeles built before 1980 often sit on unreinforced slabs with no perimeter footing. If the slab is cracked or settled, you’re looking at significant foundation work before framing can start. The second biggest driver is utility distance. Detached garages at the back of a long lot, 60 or 80 feet from the main house, need longer trenching runs for sewer, water, and power, and trenching in LA clay is not cheap.
Some homeowners ask about prefab or panelized options to control cost and timeline. We work directly with Abodu, Cover, and Dvele products when the lot and budget fit. These systems can compress the construction phase by weeks because wall panels and roof assemblies arrive pre-engineered. Other homeowners prefer conventional stick framing with James Hardie siding for maximum design flexibility. Either way, the price is written before work starts, and the guarantee is the same.
The only way to know your exact number is a site visit. Estimates are free, and the price we give you is in writing before any commitment. Call (213) 698-7116 to schedule a walkthrough.
FAQs – Detached Garage Conversion
How much does a detached garage conversion cost in Los Angeles?
A detached garage conversion in Los Angeles typically costs $180,000 to $320,000 for a complete permitted ADU with kitchen and bathroom. The wide range comes down to foundation condition, utility trenching distance, and finish level. Most projects land between $220,000 and $280,000 after design, permitting, and construction are included. Call (213) 698-7116 and we’ll give you a written price after one site visit, no obligation.
Do I need a permit for a detached garage conversion in LA?
Yes, every detached garage conversion in Los Angeles requires a building permit from the Los Angeles Department of Building and Safety, and most also require electrical, plumbing, and mechanical permits. Work done without permits can be red-tagged, and unpermitted square footage can complicate a future sale or refinance. We handle the full permit package as part of every project.
Is it cheaper to convert a detached garage or build a new ADU from scratch?
Converting a detached garage is almost always cheaper than building a new ADU from scratch in Los Angeles, typically saving $50,000 to $120,000 because the foundation, walls, and roof are already standing. You save on structural work, and you avoid some planning review time. If the existing garage is in poor condition, the savings shrink, and sometimes a teardown and rebuild from a Boxabl or Plant Prefab system makes more sense. We’ll tell you honestly which path fits your lot and budget.
Can you convert my detached garage into a rental unit in Los Angeles?
Yes, a detached garage converted under California ADU law is a legal rental unit in the city of Los Angeles, provided it meets all building, health, and safety codes and has its own entrance, kitchen, bathroom, and utility connections. ADUs in LA rent for $1,800 to $2,800 per month depending on size, location, and finish level. Call (213) 698-7116 if you want to talk through what your specific garage could produce in rent.
How long does a detached garage conversion take in Los Angeles?
Most detached garage conversions in Los Angeles take 6 to 10 months from the first design meeting to the final inspection, with permitting accounting for 2 to 4 of those months depending on the scope and any utility upgrades needed. Prefab systems from Abodu or Cover can compress the construction phase, but the city review timeline stays roughly the same. We’ll give you a realistic schedule in writing as part of your project scope.
Why Los Angeles Homeowners Choose Lodgewick ADU Los Angeles
Los Angeles is a dense market for contractors, and homeowners here have seen every version of the same story: a low initial bid that climbs after demolition starts, a crew that disappears for weeks, a finished garage conversion that leaks at the first winter rain. We built Lodgewick ADU Los Angeles around the opposite approach, and it has a name: The Kingswell Way. Price first, in writing. A real arrival window, kept. A clean site every single day. A written guarantee on every job. A return visit, free, if the work fails within 365 days.
Russ Delmar leads the Los Angeles operation. Since 2010, the Kingswell family has built its reputation on accountability, not adjectives. When you call (213) 698-7116, a live person answers, 24 hours a day, 7 days a week. Not a voicemail tree, not a chatbot. If you have a question about your build at 2 a.m., someone picks up.
We also know this city’s codes and quirks. Los Angeles hillside lots have different setback and drainage rules than flat Mid-City lots. Older garages in neighborhoods like West Adams and Jefferson Park often have unpermitted additions from decades past that need to be untangled before a conversion can proceed. Garages in the Valley deal with different soil and heat exposure than garages near the coast. None of this is a mystery to our crew, because we’ve done it in this city, block by block.
Whether you’re planning a rental unit behind your home in Mar Vista or a quiet studio for your mother-in-law in North Hollywood, the process starts with one conversation. You’ll get a straight answer, a written price when we see the property, and a guarantee that follows the work for a full year. That’s the deal.

Call (213) 698-7116 today. We’ll walk your property, give you a real number, and put it in writing before you commit to a single thing.
