- ADU & In-Law Suite · Clay County
ADU Cost and Permits in Clay County, FL (2026)
An accessory dwelling unit (ADU) in Clay County, FL runs $40,000–$95,000 for a garage conversion, $80,000–$220,000 for an attached in-law suite addition, and $150,000–$450,000+ for a detached new-build ADU. Clay County requires a Conditional Use Permit through the Planning and Zoning Division on top of standard building permits — and Florida's 2026 ADU statute (HB 1239) preempts some local restrictions but doesn't eliminate the planning review. Most HOAs in Fleming Island and Eagle Harbor still restrict ADUs in their covenants.
