Vacaville, CA Fire Regulations: Backyard Fires (2026)

There is a key distinction in unincorporated Solano County between a recreational backyard fire and open burning of vegetation. A recreational fire (a small wood or charcoal fire for warmth or enjoyment) is governed by the California Fire Code, which Solano County adopted in its 2025 edition. Under CFC Section 307.4.2, a recreational fire must be at least 25 feet from any structure or combustible material and must be constantly attended until extinguished, with a water source nearby. Burning leaves, prunings, or yard-waste piles, by contrast, is open burning regulated by the Yolo-Solano AQMD (northeastern county) or Bay Area AQMD (western/southern county): it is allowed only on approved burn days, only with the local fire district's authorization, and only for dry vegetative material. Burning trash, plastics, construction debris, and other non-organic materials is always prohibited. During red-flag warnings, high fire danger, or local burn bans - frequent in summer and fall across the wildfire-prone hills - all open and recreational outdoor fires may be suspended by the fire authority. Propane and natural-gas devices are generally allowed when wood fires are restricted and produce no smoke.
