Lot sizes here mean an ADU rarely fights setbacks. The constraints that do bite are utility capacity and seismic soils, both cheaper to test early. Plan review here runs through City of San Bernardino Building and Safety, with Planning review on new construction, with San Bernardino County Fire on access and life safety. Typical experience is roughly 6 to 12 weeks to permit on residential submittals.
1950s to 1970s single-family on generous lots, which makes detached ADUs unusually straightforward here. On the commercial side, warehouse, logistics and light industrial tenant improvements dominate commercial demand. Those two facts explain most of what is easy and most of what is expensive here.
Development impact fees are lower than coastal cities, so land and construction, not fees, drive the budget. 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.
