Summary
Outside a Skagit County Fire District, SCC 14.10.080(1) bars a building permit altogether, but SCC 14.10.080(2)(c) lets the county issue one for a single-family home or accessory building anyway if it installs NFPA 13D sprinklers, clears vegetation, and meets other Fire Marshal conditions, with narrow size-based exceptions.

Full Breakdown
080(1) sets the baseline rule for unincorporated Skagit County outside any of its Fire Districts: no building permit may issue for a structure there at all. Subsection (2) carves out exceptions, and (2)(c) is the one that lets ordinary homeowners build: in zones other than Industrial Forest-NRL, the county will permit a single-family dwelling or accessory building outside a fire district if it meets, or the Fire Marshal accepts a comparable alternative to, five conditions: approved noncombustible roofing, slash abatement within 200 feet of the structure, a vegetation-free safety zone of 30 feet on level ground and 100 feet downhill on sloped ground, sprinklers installed to NFPA 13D, and on-site availability of 300 gallons of water with 400 feet of one-inch fire hose and a gas-powered pump.
Subsection (2)(c)(v) exempts two narrow categories from the sprinkler condition specifically: unheated accessory structures of 800 square feet or less sited 20 feet from any other building, and vacation cabins of that size not used as a full-time residence. A broader exception in (2)(e) drops the sprinkler requirement entirely for a lot that was already legally platted before the county's interim controls took effect on June 11, 1990, provided the resulting dwelling or accessory building does not exceed 1,500 square feet of heated space. Saltwater island parcels face the same sprinkler and defensible-space package under (2)(d).
040(2)(b) requires any residential land division outside a fire district to prove a water supply on every lot adequate in flow and pressure for an NFPA 13D system before the Skagit County Fire Marshal will approve the division.
Violations & Fines
A single-family home built outside a Skagit County Fire District without the required NFPA 13D sprinklers, defensible-space clearing, and noncombustible roofing has no valid building permit under SCC 14.10.080(1); the Director may authorize an alternative package only if the Fire Marshal finds it comparable, and the pre-1990 lot and small-accessory-structure exceptions in (2)(e) and (2)(c)(v) are the only routes around the sprinkler condition.
