Manufactured home requirements:

• Florida septic permits are now a state DEP program, but this county's health department Environmental Health office still takes the applications and issues the permits locally

Manufactured Home Notes

• Duval County is consolidated with the City of Jacksonville, so nearly all permitting runs through the city's Building Inspection Division rather than a separate county office
• Permits are searched and submitted online through the JaxEPICS permit portal
• Beach communities (Jacksonville Beach, Atlantic Beach, Neptune Beach) and Baldwin permit separately

Florida installations follow FS 320 and Rule 15C-1/15C-2 (DHSMV) with licensed installers and installation decals; county building permits, tie-downs and wind-zone compliance apply.
