Outdoor kitchens in Boise require separate trade permits from Planning and Development Services: building permit for structural elements, mechanical permit for gas lines under the IFGC, plumbing permit for water connections, and electrical permit for outdoor outlets. The 2018 IRC and 2017 NEC with Idaho amendments apply. Foothills Hillside Overlay and Historic Preservation Commission review may apply.
Boise administers the 2018 International Residential Code (IRC), 2018 International Fuel Gas Code (IFGC), 2018 International Plumbing Code (IPC), and 2017 National Electrical Code (NEC) with Idaho amendments through Planning and Development Services (PDS). Built-in outdoor kitchens require: (1) Building permit for any structural slab over 200 sq ft, masonry counter walls, foundation, or roofed pergola/pavilion under the IRC; sheds and outdoor kitchens under 200 sq ft with no utilities are typically permit-exempt under Boise Development Code; (2) Mechanical permit for any new natural-gas line extension to a built-in grill under the IFGC, including pressure test and final inspection — Intermountain Gas Company is the local utility for most of Boise; (3) Plumbing permit for outdoor sinks, ice-maker lines, or hose bibbs under the IPC with backflow prevention required if connected to potable supply; (4) Electrical permit for any new outdoor circuits, GFCI-protected outlets, lighting, or refrigerator/freezer circuits under the NEC — outdoor outlets must be in 'wet location' rated enclosures with weatherproof in-use covers. Zoning compliance under Boise Title 11 Chapter 11-04: outdoor kitchens are accessory structures subject to setback rules, typically 3-5 ft side and rear in R-1A through R-3 districts. Foothills Hillside Development Overlay: properties in the Foothills require additional review for hillside drainage, wildfire risk, and viewshed impact. Historic Preservation Commission (HPC) review applies in North End, East End, Warm Springs, and Hyde Park historic districts for visible permanent installations. Stand-alone freestanding grills with no gas line or electrical connection do not require permits.
Unpermitted gas, electrical, or plumbing work: PDS stop-work order, double permit fees on after-the-fact applications, and mandatory exposure of concealed work. Unpermitted gas lines may prompt Intermountain Gas service disconnection. Foothills Overlay violations: erosion control issues and possible Idaho DEQ stormwater enforcement. HPC violations may require removal at owner expense.
