ADU rules in Charlotte County, FL — also called accessory dwelling unit regulations or granny flat ordinances — cover setbacks, owner-occupancy, parking, and permit requirements.
Charlotte County regulates accessory dwelling units through its zoning code, with setbacks, utility connections, and extra parking. Florida sets no statewide ADU mandate.
Florida has no statewide ADU mandate, so Charlotte County controls accessory dwellings through its Zoning Division and land development regulations. Where allowed, a second dwelling must stay clearly secondary to the main house, meet accessory-structure setbacks, connect to approved central water and sewer or an approved septic system, and provide added parking. The unit must meet Florida Building Code wind and flood loads for this coastal county. Port Charlotte's platted deed restrictions and HOA covenants often bar a second dwelling even where county zoning might allow one, so check your plat restrictions before designing an addition.
An unpermitted ADU brings building-code enforcement and a retroactive permit or removal order. Occupying an uninspected dwelling without a certificate of occupancy is a code violation with daily fines.
