ADU Design & Permitting for Fullerton owners, reviewed by City of Fullerton Community Development, typically 6 to 12 weeks to permit for residential submittals.

North Orange County · Orange County
Our Fullerton office covers North Orange County. Larger lots here mean detached ADUs pencil more often than they do on the Westside. Plan review here runs through City of Fullerton Community Development, Building and Safety, with Fullerton Fire Department on access and life safety. Typical experience is roughly 6 to 12 weeks to permit for residential submittals.
1920s craftsman near downtown and 1950s to 1960s tract north and west, with large lots. On the commercial side, downtown restaurant and retail work with parking, grease and health department sequencing. Those two facts explain most of what is easy and most of what is expensive here.
School district fees and sewer connection charges are the two lines that move most. We put the local fee picture into the first budget, because a number that ignores school, sewer and utility charges is not a budget, it is an advertisement.
We work throughout Fullerton ZIP codes 92831, 92832, 92833 and 92835, including Downtown Fullerton, Raymond Hills, Sunny Hills, Golden Hill. Two addresses in the same ZIP can still sit under different overlays, so we review the parcel rather than the postcode.
