Chimney termination must follow the 2-10-3 rule (IRC R1003.9): 3 feet above the roof penetration, 2 feet above any building portion within 10 feet horizontally.
Wood stove installation requires a mechanical permit. The stove must be EPA-certified under 40 CFR Part 60 Subpart AAA (2.0 g/hr particulate matter emissions, effective May 2020). Pre-EPA uncertified stoves cannot legally be installed as residential heating appliances. Clearances to combustibles per NFPA 211 / UL 1482 listing. Washington note: Wood stove operation is restricted during Stage 1 and Stage 2 burn bans under WAC 173-433 when PM-2.5 exceeds thresholds.

Chimney height requirements must comply with IRC R1003.9 (3 ft above roof penetration, 2 ft above any point within 10 ft horizontally).
