ADUs and room additions in San Diego
If you need extra space for family, guests, or rental income, we design and build custom ADUs that blend perfectly into your existing property.
When your needs grow, we make space. Our room additions are carefully planned and beautifully executed to expand your home without disrupting its character.
ADU, junior ADU, or addition?

Frequently asked questions
Do I need a permit to build an ADU?
Yes. ADUs require permits, but California and San Diego have streamlined the process and limited how cities can restrict them.
What size ADU can I build?
Detached ADUs of up to 1,200 square feet are allowed on most San Diego single-family lots, and state law protects your right to at least an 800 square foot unit on nearly any lot.
Can I have both an ADU and a junior ADU?
On most single-family lots in San Diego, yes: one ADU plus one JADU carved out of the main home.
Will an ADU add value to my property?
A permitted ADU adds livable square footage and rental potential, both of which appraisers and buyers recognize. Keeping the unit fully permitted is what protects that value at resale.
