FL Outdoor Kitchen & Pool House Plumbing Permit Guide

Do I Need a Permit for Outdoor Plumbing?

Yes — almost always. Any new gas line, outdoor sink, or plumbing fixture connection in Florida requires a permit pulled by a licensed plumber (CPC) or gas contractor (CGC). Unpermitted outdoor kitchens are flagged at resale and create insurance liability.

Pool House vs Outdoor Kitchen — Key Differences

• Outdoor kitchen (attached or detached): Plumbing + gas permit
• Pool house / cabana (with plumbing): Building + plumbing + gas
• Pool house with bathroom: Building + plumbing + electrical
• Outdoor sink only (no gas): Plumbing permit
• Natural gas grill only (no water): Gas permit only
• Propane (portable tank): Depends on jurisdiction. Portable tanks under 20 lbs typically no permit; permanent 250–1,000 gal tank requires permit and often a site plan.

FL County Permit Requirements — Outdoor Kitchen

• Miami-Dade: Gas sub-permit required (CGC or CPC-G); plumbing sub-permit for outdoor sink; structural permit if new structure; 5 ft min setback; buried gas line permit required. Portal: iBuildMiami.
• Broward: Gas permit (CGC/CPC-G); building permit if attached; accessory structure permit if detached; full building + sub-permits for pool house; reclaimed water needs BCWWS approval.
• Palm Beach: Gas line permit for all new runs; outdoor sink permit even for existing lines; building+plumbing+electrical for pool house with bath; reclaimed needs PBC Water Utilities approval. Portal: PBC IMS.
• Orange/Orlando: Gas permit (CGC/CPC-G); building permit for enclosed SF; gas+plumbing sub-permits for open-air kitchen; reclaimed via OUC or Orange County Utilities.
• Hillsborough/Tampa: Gas permit (CGC); CPC for any water connection; building permit for separate pool house; City of Tampa vs unincorporated = two separate AHJs.

Pool House / Cabana Permit Process

1. Determine Structure Type — Enclosed (4 walls + roof) needs building permit with stamped plans by FL engineer/architect. Open structures may need only plumbing/gas sub-permits.
2. Zoning & Setback — FBC R302 and local zoning. Pool houses typically 5–10 ft from property lines, 10 ft from pool edge.
3. Submit Building + Sub-Permits — Building (structural), plumbing (CPC), electrical, gas (CGC/CPC-G). All tied to master permit.
4. Rough-In Inspections — Plumbing (DWV+supply) and gas (pressure test at 1.5x MAWP per NFPA 54 8.2, hold 10 min). Plumbing DWV test: 10 PSI per FPC 312.
5. Final Inspections & CO — Building, plumbing, electrical, gas. Habitable space may need CO. May affect homeowner's insurance premium.

Reclaimed Water for Outdoor Use

Reclaimed (reuse) water is mandated by many FL water management districts for irrigation. NO cross-connection between reclaimed and potable (FDEP Chapter 62-610). - Pipe color: Purple (Pantone 522) - Min separation from potable: 10 ft horizontal / 18" vertical - Outdoor shower: NO (body contact prohibited) - Irrigation: Yes, with approved backflow preventer - Toilet flushing: Yes, with dual-pipe system - Backflow: RP or DCVA at point of connection

Cross-connecting reclaimed to potable violates FDEP rules and FL Statute 403. Fines up to $10,000/day.
