Building permits, zoning and septic rules in Palm Beach County, Florida

Yes. Unincorporated Palm Beach County requires building permits before erecting, altering, constructing or installing buildings, structures or service systems¹. The Building Division uses the Florida Building Code, 8th Edition (2023), with Palm Beach County amendments^9,10. Permitted construction must be inspected at the applicable phases, and covered or inaccessible work may require certification by a design professional¹. An eligible owner-builder must submit an Owner Builder Affidavit and Disclosure Statement, and the permit and inspection rules still apply¹. A qualifying nonresidential farm building, farm fence or farm sign on bona fide agricultural land may receive an exemption after county review and a $200 fee, but a dwelling does not qualify and floodplain requirements still apply⁸.

The Palm Beach County Building Division handles building permits for unincorporated land through ePZB². The main office is at 2300 N. Jog Road, West Palm Beach, FL 33411; call 561-233-5100¹¹. Municipal offices handle building permits in Boynton Beach¹², Lake Worth Beach¹³, Village of Royal Palm Beach¹⁴, Village of Palm Springs¹⁵ and Village of North Palm Beach¹⁶. Septic permitting stays with the Florida Department of Health in Palm Beach County⁴. County review checks zoning, code, contractor licensing, work value and required sub-permits¹⁰. The March 2026 increase of 2.7% in several county fees excludes building permit fees; use the PZB Fees menu for the schedule¹⁷. Impact fees use the rates effective when the building permit is issued¹⁸.

Every property in unincorporated Palm Beach County has a zoning district, and county overlay rules may also apply^3,19. Municipal zoning applies in West Palm Beach²⁰, Boca Raton²¹, Boynton Beach²², Lake Worth Beach²³, Riviera Beach²⁴, Village of Palm Springs²⁵, Belle Glade²⁶ and Village of North Palm Beach²⁷. Septic permitting remains with the Florida Department of Health in Palm Beach County⁴. County minimum lot size, setbacks, height and maximum building coverage vary by district and applicable development or overlay standards^3,5,28. Setback tables distinguish front, side, side-street and rear yards; some planned-development setbacks are measured from the inside edge of perimeter landscape buffers²⁸. Standard-district examples include minimum lots of 1 acre in PC, 10 acres in AP and 5 acres in AGR²⁸. Before buying land to split, ask the Zoning Division how Article 11 subdivision, platting and required-improvement standards apply to the proposal; call 561-233-5200 or email PZB-ZonePOC@pbc.gov^5,19.

The Florida Department of Environmental Protection implements the applicable septic statutes and regulations, while the Florida Department of Health in Palm Beach County continues local septic permitting and inspection⁴. Palm Beach County septic systems require local health-department permitting, and septic plans must receive approval before the building permit can issue⁶. Final septic approval must be entered in the building department's system before a certificate of occupancy is issued, and an owner-authorized private provider may perform the inspection^4,6. A state permit applies when a septic system is constructed, installed, modified, abandoned or repaired, and the process includes a site evaluation²⁹. Palm Beach County's soil survey rates 0% of county soils as free from severe limitations for a conventional septic drain field, making parcel-specific evaluation especially important³⁰. For a private drinking-water or irrigation well, the driller must submit a location plan before drilling; completed wells are inspected, and drinking wells need a satisfactory bacteriological report⁶.

We could not confirm a general allowance for long-term RV living or temporary camping on ordinary private land in unincorporated Palm Beach County; ask the Zoning Division about the parcel and proposed use⁵. County recreational-vehicle planned development districts serve tourist-oriented stays by temporary residents, not permanent homes³¹. In a Special Flood Hazard Area, an RV may stay fewer than 180 consecutive days, or must be fully licensed and ready for highway use; that flood rule does not establish zoning permission on ordinary private land³². Palm Beach County defines a Cottage Home as a detached dwelling of up to 1,000 square feet per unit, allowed only in certain districts with approvals; not every tiny home qualifies⁷. We could not confirm a countywide minimum dwelling size; ask the Zoning Division before choosing plans⁵. An off-site-constructed dwelling must be allowed as of right where single-family detached dwellings are allowed, subject to generally applicable permitting, installation, health, utility, setback and zoning requirements³³.

1. Confirm whether the parcel is unincorporated, then use the zoning map and ask the Zoning Division for its district, overlays, allowed residential use, lot size, setbacks, height and coverage limit^3,5,19.
2. Determine whether the site will use sewer or septic; septic plans need local health-department approval before the building permit can issue⁶.
3. If a private well is planned, have the well driller submit the location plan before drilling⁶.
4. Submit plans and supporting documents through ePZB or to the county Building Division; use the municipality's office if the parcel is incorporated^2,34.
5. If acting as owner-builder, submit the required affidavit and disclosure statement¹.
6. Complete the required building inspections and obtain final septic approval before occupancy when the project uses septic^1,6.

Before buying in unincorporated Palm Beach County, ask the Zoning Division to check the parcel’s district, overlays, residential use and development standards; ask about subdivision and platting if you intend to split the land^3,5,19. Check septic feasibility early because 0% of county soils are rated free from severe limitations for a conventional drain field³⁰. If a structure lies in a FEMA flood zone, it must comply with applicable flood regulations even when an agricultural exemption might otherwise apply⁸. We could not confirm when county driveway approval is required; ask the Building Division which road authority must approve access¹¹. Budget for carrying costs: the typical home-insurance premium is about $8,444 per year, while the effective property-tax rate is about 0.9% and the median annual property-tax bill is about $3,600³⁰. Private wells also require advance location review and later completion steps⁶.
