Kittitas County IR1 and IR2 noncombustible appendage path

Kittitas County Code 20.10 prints approved noncombustible material as one path for attached unenclosed accessory structures and projections such as decks in IR1 and IR2.

This record covers only a documented noncombustible deck product path. Attachment to habitable space, the complete appendage construction, official IR class, water and defensible-space inputs, project scope, and County approval remain checks.
