How Vacaville Handles Fire Regulations: A Practical Guide

Vacaville maintains 100 local ordinances across all categories, and 6 of those deal specifically with fire regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Vacaville falls on the strict-to-permissive spectrum compared to other cities.

Fire Pit Rules

Vacaville adopts the 2022 California Fire Code through Vacaville Municipal Code Chapter 15.20.270 et seq. (Fire Code of the City of Vacaville). Recreational fires under CFC Section 307.4.2 may be no more than 3 feet in diameter and 2 feet tall, must be at least 25 feet from any structure or combustible material, and only clean firewood may be burned. The Vacaville Fire Department enforces these rules and may order any fire extinguished.

Key details: Recreational Fire Size: Max 3 ft diameter x 2 ft height (CFC 307.4.2). Structure Setback: 25 ft open fire / 15 ft portable fireplace. Local Code: VMC Chapter 15.20.271 (adopts 2022 CFC). Air District: Yolo-Solano AQMD (Don't Light Tonight). Allowed Fuel: Clean dry firewood — no trash, leaves, treated wood.

Vacaville Fire Department or any peace officer may order an unsafe recreational fire extinguished. Violations of the adopted California Fire Code through VMC 15.20.270 et seq. are subject to administrative citation and the general penalty provisions of the Vacaville Municipal Code. Wood-burning on a YSAQMD 'Don't Light Tonight' day can draw a separate air-district civil penalty, and any escape onto neighboring property triggers full suppression-cost liability under California Health & Safety Code §13009.

Brush Clearance

Vacaville requires property owners to keep land clear of dry weeds, vegetation, and rubbish under Vacaville Municipal Code Chapter 8.04 (Abatement of Weeds and Rubbish). On or about June 1 each year, Code Enforcement inspects properties citywide. Parcels in or adjacent to State Responsibility Areas or the Vaca Mountains foothills also must maintain 100 feet of defensible space under California Public Resources Code §4291 / Government Code §51182.

Key details: Local Code: VMC Chapter 8.04 (Weeds and Rubbish Abatement). Annual Inspection: On or about June 1 by Code Enforcement. Defensible Space: 100 ft per PRC §4291 / Govt. Code §51182. Enforcement: Vacaville Fire Dept Code Enforcement (707-449-5693). Lien Authority: Unpaid abatement costs become lien on property.

If a property owner fails to abate weeds or rubbish after notice under VMC 8.04, the City may perform the work itself and assess the costs as a civil debt, lien, or special assessment against the property. The Vacaville City Council annually places liens on non-complying properties on the Solano County property tax roll. Failure to maintain PRC §4291 / Govt. Code §51182 defensible space carries CAL FIRE civil penalties up to $500 (first offense) and $1,500 (second offense). Burning to clear weeds without written Fire Chief approval is a separate violation under Chapter 8.04.

Compared to other cities, Vacaville takes a harder line on brush clearance. The enforcement and penalty structure reflects that.

Outdoor Burning

Open burning of vegetation, yard waste, or rubbish inside Vacaville City limits is unlawful under Vacaville Municipal Code Chapter 8.04 unless the Fire Chief has issued written permission. The Yolo-Solano Air Quality Management District also regulates outdoor burning regionally and prohibits all burning on declared 'Don't Light Tonight' no-burn days. Most residential yard-waste burning is effectively banned.

Key details: City Open-Burning Ban: VMC Ch. 8.04 — unlawful without Fire Chief permission. Air District: Yolo-Solano AQMD (no-burn days Nov–Feb). Recreational Fires: Allowed per CFC 307.4.2 (no-burn days excepted). Prohibited Material: Trash, treated wood, plastic, pallets, debris. CAL FIRE Burn Permit: burnpermit.fire.ca.gov (SRA areas only).

Burning weeds, rubbish, or yard waste in the City without the Fire Chief's written approval is a violation of VMC Chapter 8.04, subject to abatement cost recovery and the City's general penalty provisions. YSAQMD civil penalties for burning on a no-burn day, burning prohibited materials, or burning without an agricultural permit typically start at several hundred dollars per occurrence and escalate sharply for repeat violations. A negligently set fire that escapes triggers full CAL FIRE suppression-cost liability under California Health & Safety Code §13009.

Compared to other cities, Vacaville takes a harder line on outdoor burning. The enforcement and penalty structure reflects that.

Propane Storage

Propane (liquefied petroleum gas) storage in Vacaville is governed by California Fire Code Chapter 61, adopted through Vacaville Municipal Code Chapter 15.20.271. Residential containers under 125 gallons water capacity (the typical 20-lb BBQ tank up through a 100-lb cylinder) have no minimum setback if installation conditions are met; containers 125–500 gallons require a 10-foot separation from buildings, property lines, and public ways.

Key details: Code Reference: VMC 15.20.271 — CFC Chapter 61 (LPG). Under 125 gal Water Capacity: No required setback if CFC §6104.3 met. 125–500 gal: 10-ft setback from building / property line / public way. 501–2,000 gal: 25-ft setback (Table 6104.3). Max Installation: 2,000-gal aggregate water capacity.

Improperly stored propane containers — over capacity, too close to a structure or property line, in a basement, or beyond residential exempt quantities without a Fire Department operational permit — are violations of VMC 15.20.271 (adopted CFC Chapter 61). The Vacaville Fire Department can order corrective action, impound improperly stored containers, and issue administrative citations. Where storage creates an imminent hazard, the Fire Chief may order immediate abatement.

Fireworks

All fireworks of any kind are illegal in the City of Vacaville under Vacaville Municipal Code Chapter 9.62 (Fireworks Regulation). In 2022 the City Council strengthened the ordinance to authorize City staff to cite the property owner whenever any firework is stored or used on the property, regardless of the amount or type. Dangerous fireworks carry an administrative fine of $1,000 per occurrence plus a 10% late charge.

Key details: Status: All fireworks illegal year-round. Code Reference: VMC Chapter 9.62 (Fireworks Regulation). Administrative Fine: $1,000 per occurrence + 10% late charge. Property-Owner Liability: Owner cited regardless of individual user (2022 update). State Backup: Cal. H&SC §12677 (misdemeanor/felony).

An administrative fine of $1,000 per occurrence applies to anyone who possesses, uses, stores, sells, or displays dangerous fireworks under VMC 9.62, plus a 10% late charge if the fine is not timely paid. Property owners can be cited regardless of who actually used the fireworks. Dangerous-fireworks possession is additionally a state misdemeanor under H&SC §12677 (or a felony at higher quantities), and anyone whose fireworks cause a fire is liable for full CAL FIRE suppression costs under H&SC §13009.

This is not one of those rules that cities tend to ignore. Vacaville actively enforces its fireworks requirements.

Wildfire Zones

Portions of eastern and southern Vacaville — including Lagoon Valley Regional Park, the Vaca Mountains foothills, Browns Valley, and the slopes around Pleasants Valley — are mapped in the State Fire Marshal's Local Responsibility Area Fire Hazard Severity Zone map (released Feb 24, 2025) as Moderate, High, or Very High Fire Hazard Severity Zones. Vacaville's City Council was required to designate the zones by ordinance within 120 days of receiving the OSFM recommendation. Designation triggers defensible-space, Chapter 7A construction, and Natural Hazard Disclosure obligations.

Key details: Mapped Areas: Lagoon Valley, Vaca Hills, Browns Valley, Pleasants Valley slopes. OSFM Map Released: Feb 24, 2025 (City ordinance required within 120 days). Building Standard: Cal. Bldg. Code Chapter 7A (WUI) in VHFHSZ. Local Buffer: 50 ft non-combustible — VMC Ch. 14.20.290. Disclosure: California Civil Code §1103 at sale.

Substantial new construction or remodel within a mapped FHSZ that fails to meet California Building Code Chapter 7A WUI standards is a building-code violation: the City can issue a stop-work order and require corrective construction. CAL FIRE civil penalties for failing to maintain defensible space are up to $500 for a first offense and $1,500 for a second offense. Sellers who fail to deliver the FHSZ disclosure under Civil Code §1103 can face civil liability from the buyer. New subdivisions adjacent to open-space wildfire land that omit the VMC 14.20.290 fifty-foot buffer are not approvable.

This is one of the stricter rules in Vacaville's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.
