Frequently Asked Questions
Can I convert my garage into an ADU in Gardena?
Yes. Most detached and attached garages in Gardena are eligible for conversion, as long as they meet basic structural, safety, and fire-separation requirements. We review your garage during the ADU consultation and tell you what upgrades are needed to make it a legal living unit.
How big can an ADU be in Gardena?
Most ADUs in Gardena can be 400–1,200 sq. ft., depending on your lot size, zoning (R-1 or R-2), distance from property lines, and whether the ADU is attached or detached. Garage conversions are typically between 350–500 sq. ft., while detached backyard ADUs can go up to 1,200 sq. ft.
Do I need extra parking for an ADU in Gardena?
In most cases, no additional parking is required, especially if your home is within ½ mile of a bus stop or transit route - which includes most of Gardena. Detached, attached, and garage conversion ADUs usually qualify for parking exemptions.
Does the City of Gardena allow two-story ADUs?
Yes, two-story ADUs are allowed in many parts of Gardena, as long as they meet height limits and privacy screening requirements. These are especially useful for smaller lots where backyard space is limited.
How long does it take to get ADU permits approved in Gardena?
Gardena operates under California’s AB 68/AB 2221 laws, which require cities to review ADU applications within 60 days. However, real processing time may vary from 6–12 weeks, depending on your property and submittals.
Does Direct ADU help with ADU design and engineering, or just construction?
We handle everything - including architectural plans, structural engineering, Title 24 compliance, interior layout, permit submittals, city corrections, and full construction. You won’t need to hire separate designers or engineers.
