Jacksonville, FL Accessory Structures: ADU Permits (2026)

On November 9, 2022, the Jacksonville City Council adopted Ordinance 2022-0448-E (Keeping Our Families Together Act), amending Zoning Code Ch. 656 to allow ADUs in nearly all single-family residential zoning districts including RR-Acre, RR-1, RR-2, RLD-150, RLD-100, RLD-90, RLD-70, RLD-60, RLD-A, and RLD-B (previously ADUs were limited to RLD-TND traditional neighborhood districts). Permits are filed through JaxEPICS at https://jaxepics.coj.net/ as a single combined building, electrical, plumbing, mechanical, and zoning review. The Planning and Development Department conducts the zoning portion; the Building Inspection Division conducts MEP and structural review. Plans must show site plan with setbacks, lot coverage, square footage, floor plan, elevations, foundation details, and connection method for utilities. Florida HB 1339 (signed 2024) requires Jacksonville to process ADU applications that meet objective standards via ministerial review (no public hearing, no discretionary findings). Historic districts (Springfield, Riverside-Avondale, etc.) may require additional Historic Preservation Commission certificate of appropriateness review. Total permit and impact-fee costs commonly run $3,000-$8,000.
