What applies to your lot
Building an ADU in Garden Grove
Who approves your ADU
City of Garden Grove: the Community and Economic Development Department reviews ADUs, and plans are submitted online through GG Ready. State law applies everywhere: a decision within 60 days of a complete application, no public hearing, and at least 800 sq ft with 4 ft side and rear setbacks.
ADU Go: free city plans
Garden Grove owns four pre-approved ADU plans that homeowners can download for free. Some site-specific work is still needed, but the design work is done.
Sewer capacity, checked early
The city asks for a sewer capacity verification with the submittal. We confirm it at the start, so it does not hold up the permit later.
Conversions of permitted space
A permitted garage or room can become an ADU with a building permit. The city asks for the permits of the existing structure, which we gather for you.
