Frequently Asked Questions
Can I build an ADU on my Jacksonville property?
Yes. Florida HB 1339 (2024) requires Jacksonville to permit ADUs by-right with ministerial (non-discretionary) approval for ADUs meeting objective standards. Owner-occupancy requirements were eliminated statewide. Impact fees are capped at the single-family rate. Contact Jacksonville Planning and Development for specific size and setback requirements for your zone.
What makes Jacksonville unique as a city government?
Jacksonville operates under a consolidated city-county government, combining the City of Jacksonville and Duval County into one government entity since 1968. This makes Jacksonville one of the largest cities by land area in the contiguous US (874 square miles). All city and county services — building permits, zoning, utilities (JEA) — are handled by the consolidated government.
Who provides utilities in Jacksonville?
JEA (Jacksonville Electric Authority) is the community-owned utility providing electricity, water, and wastewater service to most of Jacksonville and parts of surrounding counties. JEA handles both electric interconnection for solar systems and water/sewer connections for new dwelling units. JEA is one of the largest community-owned utilities in the US.
Are short-term rentals (Airbnb) allowed in Jacksonville?
Yes, with licensing. A Florida DBPR (Department of Business and Professional Regulation) Vacation Rental License is required statewide. Jacksonville also requires a Local Business Tax Receipt. Florida Tourist Development Tax (6%) and Duval County Tourist Development Tax must be collected on all STR stays. Platforms like Airbnb collect and remit these taxes.
Is my Jacksonville property in a flood zone?
Many Jacksonville properties are in FEMA-mapped Special Flood Hazard Areas (SFHAs) due to the St. Johns River and coastal proximity. Use the FEMA Flood Map Service Center (msc.fema.gov) to check your specific parcel. Properties in SFHAs require flood insurance with federally-backed mortgages. Jacksonville also participates in FEMA's Community Rating System, which can discount flood insurance premiums.
Does Jacksonville have historic district restrictions?
Yes. Jacksonville has 6 locally designated historic districts including Riverside-Avondale (one of Florida's largest historic districts) and Springfield. If your property is in a historic district or is a designated landmark, exterior alterations require a Certificate of Appropriateness from the Historic Preservation Commission before building permits can be issued. Contact Jacksonville Planning and Development for historic overlay status.
