ADU Rules in West Palm Beach, Florida

West Palm Beach is the Palm Beach County seat and the largest city on Florida's Gold Coast north of Fort Lauderdale. ADU eligibility is governed locally by Chapter 94 of the City's Zoning and Land Development Regulations.

Florida State ADU Framework

Florida has no statewide ADU mandate. Fla. Stat. §163.31771 ("Accessory dwelling units") authorizes — but does not require — local governments to adopt ADU ordinances in single-family zones after the local government finds a shortage of affordable rentals. West Palm Beach therefore regulates ADUs under its own zoning code.

Local ADU Eligibility

The City's Zoning and Land Development Regulations (Chapter 94) govern accessory apartments. Eligibility, lot-width thresholds, and dimensional standards vary by single-family district. Contact the Planning Division for a parcel-specific determination.

Historic Districts

West Palm Beach has several local historic districts (including El Cid, Flamingo Park, and Northwood). Properties in historic overlays require Historic Preservation Board review for exterior alterations, including ADU work.

Waterway and Flood Considerations

Properties near the Intracoastal Waterway and Lake Worth Lagoon may be in FEMA Special Flood Hazard Areas. Florida Building Code flood provisions and elevation requirements may apply. Verify flood zone status before planning.
