Kittitas County IR1 and IR2 one-hour appendage path
Kittitas County Code 20.10 prints one-hour fire-resistance-rated construction as one path for attached unenclosed accessory structures and projections such as decks in IR1 and IR2.
This record covers only a documented one-hour 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.
