Why Homeowners Choose Garage Conversions

Streamlined Permits

California's ADU laws make garage conversions one of the easiest projects to permit, especially in LA and OC.

400-600 sq ft Living Space

Most two-car garages convert into spacious studio or one-bedroom apartments with full kitchen and bath.

Rental income, in-law suite, home office, guest house, or multigenerational living — your garage can do it all.

FAQ

Garage Conversion Questions

Garage conversion costs vary depending on size, finishes, and complexity. Contact us for a free estimate — we provide detailed, no-obligation quotes that include all permits, design, construction, and finishes.
Yes, you need permits for a garage conversion in California. However, under AB 68 and SB 13, cities must approve ADU applications ministerially (without discretionary review) within 60 days, making the process much faster than traditional permits.
Most garage conversions take 4-6 months from permit approval to move-in. The design and permitting phase typically takes 4-8 weeks, followed by 3-4 months of construction.
Under California ADU law (SB 13), cities cannot require replacement parking when you convert a garage to an ADU. This was a major barrier that was eliminated by state legislation.
Absolutely! California law explicitly allows ADU rentals. Many homeowners generate strong monthly rental income from their garage conversion ADU in the LA and OC markets.
Garage conversions offer the highest ROI of any ADU type. Most homeowners see a full return within a few years while also gaining significant property value. Contact us for a free estimate and ROI analysis for your specific project.
Garage conversion construction commonly takes 8-14 weeks after permit approval, but every property is different. Permit processing estimates vary by jurisdiction and are not guarantees. Your construction schedule is set in your written agreement.
Yes, your property taxes will increase modestly since you're adding living space. However, the rental income from the ADU typically far exceeds the tax increase. Many homeowners see 10-15x more in monthly rental income versus the monthly tax increase.
Yes, both attached and detached garages can be converted into ADUs in California. Detached garage conversions are especially popular because they provide more privacy and separation. We handle both types regularly.
A garage conversion needs plumbing (for kitchen and bathroom), electrical (panel upgrade or sub-panel), HVAC (heating and cooling), and proper insulation. We can set up separate utility meters if desired, which is ideal for renting the unit.
