West Palm Beach's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In West Palm Beach, Florida, there are 5 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Shed Rules

Sheds in West Palm Beach require a building permit when over 100 square feet or anchored to a foundation. All sheds, regardless of size, must meet Florida Building Code wind load requirements for 170 mph design wind speed.

Key details: Permit Threshold: Over 100 sq ft. Wind Code: 170 mph design. Setbacks: 5 ft side and rear typical. Approval: FL Product Approval needed.

Unpermitted shed: $250 minimum fine, after-the-fact permit at double fee, or removal order if it cannot meet wind code.

Carport Rules

Carports in West Palm Beach require a building permit and must meet Florida Building Code 170 mph wind load with engineered anchors. Front-yard carports are restricted to driveway alignments and may not encroach on required setbacks.

Key details: Wind Code: 170 mph design. Approval: FL Product Approval. Setbacks: 5 ft side typical. Enclosure: Two open sides max.

Unpermitted carport: removal order during the next major storm warning, $250 minimum fine, plus after-the-fact permit at double fee.

Tiny Homes

Tiny homes on permanent foundations are treated as single-family dwellings or ADUs in West Palm Beach and must meet all Florida Building Code requirements. Tiny homes on wheels are classified as RVs and may not be used as permanent residences in residential zones.

Key details: On Foundation: FBC plus IRC Appendix Q. On Wheels: Treated as RV. RV Use: RV parks only. Manufactured: HUD or DBPR label.

Use of an RV as a dwelling on residential property: code citation up to $500 per day plus order to remove or hook up to permanent utilities.

This is not one of those rules that cities tend to ignore. West Palm Beach actively enforces its tiny homes requirements.

Garage Conversions

Converting a garage into living space in West Palm Beach requires a building permit, zoning compliance review, and replacement of the off-street parking that the garage previously provided. Conversions are heavily scrutinized in single-family neighborhoods.

Key details: Parking: Must be replaced on lot. Code: FBC R-occupancy upgrades. Egress: Window required in bedroom. Historic: Door appearance retained.
