Do you need a building permit in Palm Beach County, Florida?
Yes. Unincorporated Palm Beach County requires permits before erecting, altering, constructing or installing buildings, structures or service systems1. Permitted construction must also be inspected at the phases applicable to the work12. Florida uses a statewide building code, and the edition in effect when the permit application is filed governs the work for the life of that permit and its extensions13. An owner may act as the contractor, but the owner-builder route does not remove the permit or inspection requirements; the Building Division recommends using a licensed contractor9. A qualifying nonresidential farm building, farm fence or farm sign on bona fide agricultural land may receive an exemption, but a dwelling does not qualify and floodplain requirements still apply11.
Who issues Palm Beach County building permits, and how do you reach the office?
The Palm Beach County Building Division Permit Center processes building-permit applications for unincorporated Palm Beach County2. The main office is at 2300 N. Jog Road, West Palm Beach, FL 33411, and the Building Division phone is 561-233-510014. The county also lists a limited-services South County office at 345 S. Congress Ave, Delray Beach, FL 33445, with phone 561-276-138514. Applications may be submitted through the ePZB portal at any time, although another reviewing agency may have separate responsibilities2. Palm Beach County publishes a fee schedule, and the amount varies by permit type, valuation, unit, square footage or another schedule category15. For zoning questions, call the Zoning Division On Call line at 561-233-5200 or email [email protected]16.
Does Palm Beach County have zoning?
Yes. Palm Beach County administers the Unified Land Development Code and zoning districts for unincorporated land46. The code separates overlays and zoning districts from use regulations, so a parcel's district and any overlay matter to what can be built or occupied there6. Subdivision, platting and required improvements are also regulated under the county code17. We could not confirm one countywide setback, minimum lot size, building height or lot-coverage figure; the Zoning Division On Call staff specifically answers questions about allowed uses, setbacks, height and lot coverage16. Palm Beach County's specific accessory-dwelling rules also remain unconfirmed, so ask the Zoning Division about an accessory unit before relying on Florida's law allowing local governments to adopt an accessory-dwelling ordinance1816.
How do septic and well permits work in Palm Beach County?
The Florida Department of Health in Palm Beach County regulates, permits and monitors onsite sewage treatment and disposal in the county5. Septic plans must satisfy applicable state and county rules and receive health-department approval before the building permit can issue7. Final septic approval must be entered in the building department's system before a certificate of occupancy is issued19. A state permit applies when a septic system is constructed, installed, modified, abandoned or repaired, and the process includes a site evaluation20. Palm Beach County's soil survey rates 0% of county soils as free from severe limitations for a conventional septic drain field, making a site-specific evaluation especially important21. For a private drinking-water or irrigation well, the driller must submit a location plan before drilling; completion reporting, inspection and water testing requirements then depend on the well type8.
Can you live in an RV or tiny home on your land in Palm Beach County?
We could not confirm a Palm Beach County rule that generally allows long-term RV living or temporary camping on ordinary private land in the unincorporated county. Florida's reviewed RV rule addresses transient stays in permitted recreational-vehicle parks and recreational camps, not a separate right to occupy an RV on a private parcel1022. Ask the Palm Beach County Zoning Division whether the parcel's district permits the proposed RV use before buying or connecting utilities16. We also could not confirm a countywide tiny-home occupancy rule or minimum dwelling size. A manufactured or other off-site-constructed dwelling must be allowed as of right where single-family detached dwellings are allowed, but it still must meet generally applicable permitting, installation, health, utility, setback and zoning requirements23.
Building a home in Palm Beach County: the steps, in order
- Confirm whether the parcel is in unincorporated Palm Beach County, then ask the Zoning Division for its district, overlays, allowed residential use and property-development standards416.
- Determine whether the site will use sewer or septic; septic plans need local health-department approval before the building permit can issue7.
- If a private well is planned, have the well driller submit the location plan before drilling8.
- Submit the building-permit application to the county Permit Center through ePZB, or use the municipality's office if the parcel is incorporated23.
- If acting as owner-builder, follow the Building Division's owner-builder permit and inspection process9.
- Complete the required building inspections and obtain final septic approval before occupancy when the project uses septic1219.
What should you check before buying land in Palm Beach County?
Start with jurisdiction and zoning: confirm whether county or municipal rules apply, then verify the zoning district, overlays, permitted use and parcel-specific development standards3416. Check septic feasibility early because 0% of county soils are rated free from severe limitations for a conventional drain field21. If a structure lies in a FEMA flood zone, it must comply with applicable flood regulations even when an agricultural exemption might otherwise apply24. Confirm legal access with the responsible road authority because a county driveway requirement was not established. 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 $3,600252627. Private wells also require advance location review and later completion steps8.
Watch-outs
- Palm Beach County septic approval must come before the building permit can issue, and 0% of county soils are rated free from severe limits for a conventional drain field721.
- A qualifying agricultural exemption does not cover a dwelling or remove floodplain-management requirements11.
- Private-land RV occupancy, tiny-home occupancy and countywide minimum dwelling size remain unconfirmed; ask the Zoning Division about the exact parcel and proposed use16.
