Zoning & HOA Considerations
Fireplace and wood stove installations rarely trigger zoning review. Many California air quality districts (SCAQMD, BAAQMD) prohibit NEW wood-burning fireplaces in new construction. Chimney height requirements must comply with IRC R1003.9 (3 ft above roof penetration, 2 ft above any point within 10 ft horizontally).
If you live in an HOA community: hOAs in some communities prohibit wood-burning appliances entirely due to smoke and air quality concerns. Gas fireplaces are usually permitted. Chimney caps and exterior venting may face aesthetic review.
