City of Oceanside requires permits for all proposed construction and development in the community including the placement of manufactured (mobile) homes, mobile homes, room additions, accessory dwellings, etc.

A permit is required before commencing any construction or development within the Special Flood Hazard Area (SFHA) so that the City may determine that the proposed development meets the requirements of the National Flood Insurance Program (NFIP) and the community's floodplain management ordinance.

Note: The City of Oceanside regulates Zone A99 similarly to Zone AE since the San Luis Rey Levee has not yet been accepted by the City and flood risk still exists. The previously established BFEs from the 1997 FIRMs are to be used for development purposes in this special flood hazard area. The Floodplain development regulations outlined in the City's Floodplain Management Ordinance still apply to Zone A99.
