Plan review here runs through City of Orange Community Development, with Orange City Fire Department on access and life safety. Typical experience is roughly 8 to 14 weeks, with historic review layered on inside Old Towne.
One of the largest intact historic districts in California, plus large-lot semi-rural parcels in Orange Park Acres. On the commercial side, Plaza-adjacent retail and restaurant work with facade and signage review. Those two facts explain most of what is easy and most of what is expensive here.
Historic consultant work is a normal line item inside Old Towne and should be scoped up front. 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 Orange ZIP codes 92865, 92866, 92867, 92868 and 92869, including Old Towne, Orange Park Acres, El Modena, Santiago Hills. Two addresses in the same ZIP can still sit under different overlays, so we review the parcel rather than the postcode.
