Garage Conversion Costs for Los Angeles Homes
A garage conversion can transform your barely used garage space into a totally functional and valuable part of your home. As you delve into the many ways a garage can be converted, garage conversion costs are bound to be at the forefront of your thought processes. At Oasis Builders, we help property owners with garage conversion on a regular basis. Take a look at some of the factors that, based on our experience in Los Angeles, can affect the total cost.

How Garage Conversion Costs Are Typically Estimated
Garage conversion costs in Los Angeles are rarely based on square footage alone. Accurate estimates depend on early evaluation of the existing structure, seismic and structural requirements, utility locations and capacity, and how the space will function. Reliable cost estimates follow a clear sequence, beginning with site and structural assessment, followed by defined design scope and system requirements, and only then accounting for materials, labor, permits, and utilities. Estimates prepared without this level of review tend to rely on assumptions rather than actual project conditions.

Legalities That May Affect Garage Conversion Cost
A few legal factors can be involved in determining overall garage conversion costs. Local permit and zoning requirements directly influence garage conversion costs. General contractors who work regularly in Los Angeles account for these factors early and help homeowners understand how approvals and compliance affect both scope and budget. For example, if you are in Los Angeles, garage conversions were once difficult to achieve due to zoning restrictions, but SB 1069 & AB 229 makes it much easier to undergo these projects legally.
In recent years, the City’s focus on increasing housing supply has made ADU projects more accessible by easing long-standing parking requirements and streamlining review processes. Los Angeles Department of Building and Safety now allow for easier permit tracking, inspection scheduling, and mobile access, which has helped reduce administrative delays. In many cases, Certificate of Occupancy coordination has also become more centralized, with final approvals issued automatically once inspections are passed and utility clearances are complete.
Garage Conversion Costs Associated with Chosen Design
Several types of garage conversions exist, and overall cost depends largely on how the space is intended to function. Converting a garage into a full ADU with a kitchen, bathroom, and independent living systems typically involves higher construction costs than converting the space into a non-habitable use such as a family room or home office. Design scope plays a major role in pricing, particularly when residential code requirements come into play. A few design factors that can influence cost include:
- Whether the space will involve extensive plumbing or electrical changes
- The perceived use of the space
- How much the existing garage layout will have to change
- If the garage will have to be expanded


Consider the Costs Associated with Materials and Furnishings
Materials used during the construction will naturally make up the bulk of the garage conversion cost of the project. Consider things like:
- Windows: Energy-compliant windows often require Low-E (low-emissivity) glass, dual-pane assemblies, or tempered glazing. These options cost more than basic single-pane windows but improve insulation, comfort, and Title 24 compliance.
- Doors: Costs vary widely depending on use and code requirements. Solid-core interior doors, fire-rated doors, and sliding or multi-panel exterior doors are more expensive than standard hollow-core options.
- Countertops, backsplashes, cabinets: Costs shift substantially between stock materials and semi-custom or custom solutions, especially in ADU-style garage conversions.

Figure Labor Expenses as Part of Garage Conversion Cost
The typical labor expense that will make up a portion of garage conversion cost will be roughly 10 to 20 percent of the overall cost of the total project. With that being said, you can assume some roundabout costs by adding 10 to 20 percent to overall material costs. To get a closer estimate, be sure to work with garage conversion contractors who are willing to give you free quotes upfront.


Other Garage Conversion Cost Considerations
As you start examining possibilities, a few other cost considerations may come up to think about, such as:
- If the cost of garage conversion can be recouped when you sell your home
- If you want to convert the full garage or only a portion of the garage
- How you will want to change your driveway to better accommodate your vehicle


A Word About Financing a Garage Conversion
You have several options to consider when it comes to paying for your garage conversion costs. A few property owners choose to use their own funding or savings for the project, but you may also want to consider:
- A home equity loan
- Home renovation funding
- A 203(k) construction loan
- Cash-out refinancing
With interest rates being at all-time lows over the past year, getting loans to finance your garage conversion costs may be a more logical option.
