Fullerton questions
How long does an ADU permit take in Orange County?
State law caps ADU review at 60 days from a complete application, and most Orange County cities meet that on a clean submittal. Realistically, budget three to four months from first drawing to issued permit once corrections, fire authority review and fees are included.
Do you work outside Fullerton in Orange County?
Yes. We regularly work across Anaheim, Brea, Placentia, Yorba Linda, Orange, Irvine and the surrounding cities from the Fullerton office.
