ADU (Accessory Dwelling Unit) permit in North Port, FL
Yes — you need a permit for adu (accessory dwelling unit) work in North Port.
Building an accessory dwelling unit (garage apartment, casita, etc.) is new Building-type construction. Florida's exempt list (FBC 105.2) has no Building category, so it is not exempt and needs a permit. North Port adopts the Florida Building Code by reference (Sec. 14-20); a construction traffic road fee also applies to new construction and additions per the city fee schedule.

If you skip it
