Can Your Garage Be Converted Into an ADU?
Many garages in Los Angeles can be converted into accessory dwelling units, but not every garage should be. If you want to convert a garage into an ADU in Los Angeles, the first step is determining whether the existing structure is worth keeping.
The right approach depends on the condition of the existing structure, utility access, permit history, local requirements, and what you want the finished space to provide. Some garages are strong candidates for conversion. Others require so much structural and utility work that rebuilding may be the better investment.
That’s why every Go ADU project begins with a site evaluation before we recommend a layout or provide a construction budget.
What Are the Requirements for a Garage Conversion in Los Angeles?
Before recommending a garage conversion, we evaluate whether the existing structure can be brought up to current requirements for safe, comfortable living space without making the project unnecessarily complicated or expensive.
Garage conversion requirements and approval processes vary between the City of Los Angeles, unincorporated Los Angeles County, and the individual cities Go ADU serves.
During the site evaluation, we look at:
- Foundation and slab condition
- Framing, roof, and structural integrity
- Ceiling height and interior dimensions
- Water, sewer, and electrical access
- Property lines and existing setbacks
- Natural light, ventilation, and egress opportunities
- Insulation and energy requirements
- Fire separation requirements
- Construction and occupant access
- Whether converting or rebuilding offers better long-term value
A permitted garage conversion ADU also needs a functional kitchen and bathroom, heating and ventilation, smoke and carbon monoxide alarms, and any required structural, electrical, plumbing, and fire-safety improvements.
Many Los Angeles garages were built decades ago for storage and parking, not residential use. Bringing an older structure up to current standards may require foundation corrections, framing reinforcement, insulation, new utilities, roof work, or termite repairs.
We won’t recommend a conversion just because a garage already exists. We’ll help you determine whether the structure gives you a real advantage or whether building a new ADU would give you a better, more predictable result.
Garage Conversion or New Construction: Which Costs Less?
A garage conversion isn’t automatically cheaper than building a new ADU.
In this video, Go ADU founder Gil Vaisman walks through a completed 420-square-foot garage conversion in Highland Park and explains why the homeowners chose to work within the existing footprint. Their yard was small, and building a separate structure would have taken away valuable outdoor space. The conversion made sense because it fit the property and the family’s goals.
When a Garage Conversion Makes Sense
- You want to preserve more of your backyard
- The existing footprint fits your space needs
- The garage is structurally sound
- The location allows for light, privacy, and access
- Existing setbacks make the garage footprint valuable
- You don’t need the garage for parking or storage
When New Construction Is a Better Option
- The garage has foundation, framing, roof, or termite damage
- You want more space than the garage can provide
- The existing structure limits the layout
- The garage is poorly positioned on the lot
- Utility or structural upgrades make conversion less predictable
- Keeping the garage adds more value to the property
How Much Does a Garage Conversion Cost in Los Angeles?
Most professionally built garage conversion ADUs in Los Angeles cost between $150,000 and $250,000, depending on the size of the garage, its condition, the site, and your finish selections.
That’s a realistic planning range, not a quote for every property. Two garages with similar square footage can have very different costs once the foundation, framing, utilities, access, and permit history are evaluated.
Four Factors That Influence Garage Conversion Costs
1. The Condition of the Garage
2. The Size of the ADU
3. Site Conditions
- Sewer, water, gas, and electrical access
- Electrical panel capacity
- Limited construction access
- Drainage or grading needs
- Hillside or sloped conditions
- Soil conditions
- Fire-zone requirements
- Distance between the garage and existing utilities
4. Finish Selections
Costs Beyond Construction
- Architectural design
- Structural engineering
- Title 24 documentation
- Permit and plan-check fees
- Utility upgrades
- Surveying
- Drainage or grading work
- Site restoration
- Landscaping or hardscape improvements
- Financing and carrying costs during construction

LA’s Recommended ADU Builders
We had a beautiful experience working with Gil’s team of Hugo and Daniel and they were very diligent throughout the entire process. They built our ADU from start to finish in less than 6 months all while my elderly 77 year old dad lived in the front house and they showed great consideration to him. The finishes were on point and the communication never lacked with Gil and Daniel always picking up the phone when we called. And one of the most impressive features of our experience is that for a six figure project the price we were given is the EXACT price that we paid at the end. Would definitely recommend Go ADU to take the stress out of building in the City of LA
Just finished an ADU build with Go ADU and I’m genuinely impressed with how they ran the job. Anytime something unexpected popped up—city, utilities, you name it—they told me right away and laid out options instead of just dumping problems in my lap. Communication was steady the whole way through, and I never felt like I had to chase them for updates. The unit turned out exactly how I pictured it: clean lines, solid workmanship, and ready to move into. I’d gladly bring them back for another project.

I've built several ADUs now with different contractors and this one was the easiest and smoothest to date thanks to Gil and his team at Go ADU. Communications was great throughout the process and most impressively, Gil's team actually stuck to a schedule and on the few occasions where we had to deviate, we were only off by a few days rather than weeks or months on my previous jobs with other contractors. Gil was also very responsive and accommodating to change orders and corrections -- no fuss, no pushback. Am definitely going to recommend him to other clients and investors of mine!
Hiring Go ADU for my project was finding a gem in a sea of contractors. From day one, they had a game plan that made sense and kept the project on track.
Their transparency was refreshing. No smoke and mirrors—just clear communication about timelines and costs that helped me plan ahead without any surprises.

I'm grateful for a stress-free build process, look no further than Gil, Hugo and their team.
I want to recommend Go ADU. They did a great job getting our project done. Helped us design and build.
I’m a long time real estate investor and I’ve worked with at least a dozen contractors. Gil and his team are by far my favorites. They’re the most reliable contractors I’ve ever worked with. Communication was superb — clear, realistic timelines and constant updates with photos. He and is team were highly skilled in understanding the nuances of my project. I’m thrilled with the final product and will absolutely be using GoADU again for my next project.
Gil fixed up my ADU after a nightmare contractor couldn’t get it finished according to code and kept failing inspection. He walked off the job and I was overwhelmed because construction wasn’t my lane of expertise. Gil knew how to communicate with us as a homeowner himself. He understood our point of view, was knowledge and helpful, and got the ADU finished and permitted.
Go ADU provided transparent pricing and transparent timelines. Gill provided a realistic timeframe and included detailed estimates from soup to nuts. So happy to have gone in this direction. A+++

Frequently Asked Questions About Garage Conversions in Los Angeles
Can I convert my garage into an ADU?
Many attached and detached garages can be converted into ADUs, but not every garage is a good candidate. Feasibility depends on the condition of the existing structure, utility access, permit history, local regulations, and your goals for the space. A site evaluation is the best way to determine whether a garage conversion or a new detached ADU is the better option.
Can a garage conversion ADU be designed for aging parents or family members?
Yes. Many homeowners convert their garage into an ADU to create a private, independent living space for aging parents, adult children, or other family members. During the design process, features such as wider doorways, step-free entrances, accessible bathrooms, and single-level layouts can often be incorporated to better support long-term living needs. We'll discuss your family's goals during the site evaluation and recommend a layout that's practical for today and adaptable for the future.
Do I need permits to convert my garage into an ADU in Los Angeles?
Yes. A legal garage conversion ADU requires approved plans, building permits, inspections, and final approval from the agency with jurisdiction over your property. As part of our design-build process, Go ADU prepares your plans, submits your permit application, responds to plan check comments, and manages the project through final inspection.
How much does a garage conversion cost in Los Angeles?
Most professionally built garage conversion ADUs in Los Angeles cost between $150,000 and $250,000. The final price depends on the garage's condition, size, site access, utility requirements, structural work, permit needs, and finish selections.
How long does it take to complete a garage conversion?
A typical garage conversion in Los Angeles takes about 3 to 6 months from the initial planning stages to project completion. This timeline includes obtaining permits, finalizing designs, and construction. The complexity of your project may also affect the time frame. For example, if you’re adding new plumbing systems or dealing with specific zoning restrictions, the process might take longer.
Can an unpermitted garage be converted into an ADU?
Possibly. An unpermitted garage may still be eligible for conversion, but the process often requires reviewing the property's history, preparing new plans, completing any required structural or safety upgrades, and obtaining permits before construction begins. The requirements depend on your property's location and the reviewing jurisdiction.
Is a garage conversion a good investment?
For many homeowners, yes. A garage conversion ADU can create rental income, provide housing for family members, increase usable living space, and add long-term value to your property. The best return comes from choosing the right solution for your property, whether that's converting an existing garage or building a new detached ADU.
Do I have to replace the lost parking?
Generally, California law doesn’t allow local agencies to require replacement off-street parking when a garage or other covered parking structure is converted into an ADU. Property-specific conditions should still be reviewed during design.
