How the county and cities handle ADUs.

Palm Beach County is a patchwork. The county itself permits ADUs in many unincorporated areas under its Workforce Housing program. Most of the major municipalities have their own ordinances:

  • West Palm Beach: ADUs permitted in single-family districts; 800 sq ft max.
  • Lake Worth Beach: ADUs permitted citywide; among the most permissive in the county.
  • Delray Beach: ADUs permitted in many residential districts.
  • Boynton Beach: ADUs permitted under the 2022 ordinance update.
  • Boca Raton: ADUs permitted, with the strictest rules and largest minimum lot size in the county.
  • Wellington, Jupiter, Palm Beach Gardens: permitted with varying conditions.
The common parameters: 900 sq ft max ADU size (varies), 5–10 ft setbacks, one off-street parking space, owner-occupancy required in some municipalities, long-term rental permitted everywhere, short-term rental usually restricted.
