Fire Regulations in Chico, CA: What Residents Actually Need to Know

If you live in Chico or are thinking about moving there, fire regulations are one of those things you probably won't think about until they affect you directly. Chico has 6 specific rules on the books covering different aspects of fire regulations, and some of them might surprise you.

Fireworks

All fireworks — including those classified as 'Safe and Sane' by the State of California — are banned within Chico city limits. CMC 16R.42.100 amends CCR Title 19 Ch. 6 and California Fire Code §5601 to prohibit the manufacture, possession, storage, sale, use and handling of any fireworks. The only exception is permitted public displays under CMC 16.48.020, which must follow CCR and CFC rules. This is significantly stricter than state law, which lets cities choose to allow Safe-and-Sane sales around July 4. Chico's ordinance reflects the city's wildfire-adjacent status (Camp Fire, 2018) and the dry late-summer climate of the Sacramento Valley.

Key details: Code section: CMC 16R.42.100. Scope: All fireworks banned, incl. 'Safe and Sane'. Only exception: Permitted public display per CMC 16.48.020. State law: HSC §12500 et seq.; CCR Title 19 Ch. 6. Misdemeanor: Possession of dangerous fireworks — HSC §12677.

First-tier administrative citation under CMC Title 1; misdemeanor prosecution available under HSC §12677. The City uses a social-host / parental-responsibility framework — adult occupants of a residence where fireworks are discharged can be cited. Cost-recovery for fire-suppression response is authorized when discharge causes ignition.

Compared to other cities, Chico takes a harder line on fireworks. The enforcement and penalty structure reflects that.

Wildfire Zones

Chico adopts the California Fire Code via CMC 16R.42.010 — including Chapter 49 (Requirements for Wildland-Urban Interface Fire Areas). CAL FIRE released updated LRA Fire Hazard Severity Zone maps on March 24, 2025; parts of the eastern Chico foothill fringe (Skyway / Forest Ranch edge) are mapped as High and Very-High FHSZ within or just outside the city. New construction or substantial remodel in any FHSZ must meet California Building Code Chapter 7A (ignition-resistant materials, ember-resistant vents, Class A roofs, enclosed eaves). The 2018 Camp Fire — 10 miles east in Paradise / Magalia — drives unusually rigorous enforcement.

Key details: Local adoption: CMC 16R.42.010 (adopts Cal. Fire Code). Building standard: CBC Ch. 7A — WUI ignition-resistant. FHSZ map update: CAL FIRE LRA maps — March 24, 2025. Chico zones: High/Very-High FHSZ on eastern foothill edge. Sale disclosure: AB 38 (HSC §51182/§51189).

Building permits in FHSZ are not issued without WUI-compliant plans (Ch. 7A). State PRC §4291 administrative fines up to $5,000/inspection for defensible-space failures. AB 38 sale-disclosure violations are civil actionable. Chico Code Enforcement may issue CMC 1.16 misdemeanor citations for ongoing non-compliance.

This is not one of those rules that cities tend to ignore. Chico actively enforces its wildfire zones requirements.

Fire Pit Rules

Chico Municipal Code Chapter 9.35 (Outdoor Warming Appliances with Open Flame) restricts where residents may operate fire pits, chimineas and similar open-flame warming devices. CMC 9.35.020 limits use to private property or to a city park where allowed under CMC 12.18.230. Use on public sidewalks, streets, alleys, open spaces, greenways and non-designated park areas is prohibited. The ordinance, adopted to mitigate fire risk in this WUI-adjacent community (10 miles from the 2018 Camp Fire burn scar), targets unattended or unauthorized open flames; cooking devices such as barbecues remain permitted under the exemptions in CMC 16R.42.070.

Key details: Code section: CMC Ch. 9.35 (Outdoor Warming Appliances). Allowed location: Private property; city parks per CMC 12.18.230. Prohibited location: Public ROW, greenways, undesignated park areas. Permit required: No on private property; must be attended. BBQs: Exempt under CMC 16R.42.070 if CFC-compliant.

Code Enforcement (530-879-6330) and Chico FD respond to complaints. Violations of CMC 9.35 are administrative infractions enforced under CMC Title 1 — first notice + abatement; continuing violations are misdemeanors under CMC 1.16. Unattended open flame that escapes can trigger PRC §4421/4423 reckless-burning liability and full cost-recovery for suppression.

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

Propane Storage

Chico regulates propane/LP-gas storage primarily by adopting the California Fire Code via CMC 16R.42.010, with local amendments. CMC 16R.42.020 restricts above-ground tanks of flammable and combustible liquids, and CMC 16R.42.050 amends CFC §6104.3 — Restrictions on Container Location for storage of liquefied petroleum gases — limiting where larger LP-gas containers may be sited. For typical homeowners, small DOT propane cylinders (BBQs, patio heaters) up to 5 gallons / 20 lb water capacity are allowed and exempt under CFC §6103. Larger stationary tanks (>125 gallons) require Chico Fire plan review, separation distances per CFC Table 6104.3 and NFPA 58, and may be restricted in certain zones.

Key details: Code section: CMC 16R.42.020 / .050 (adopts & amends CFC). Small cylinders: ≤5 gal / 20 lb BBQ tanks — allowed citywide. Stationary tanks: >125 gal needs Chico FD plan review. State standard: NFPA 58; HSC §13143.6. Cylinder requalification: 12 yrs from manufacture; then every 5 yrs.

Plan-check failures or unpermitted installations are corrected via Chico FD/Building Department stop-work or notice of violation under CMC Title 16R; continuing violations may be cited as misdemeanors under CMC 1.16. Retailer/refiller violations (overfilling, missing OPD valves) are enforced by the State Fire Marshal under HSC §13143.6.

Brush Clearance

The City Council declares weeds, rubbish, refuse and debris a public nuisance and runs an annual lot-clearing & weed-abatement program administered by Community Development under CMC Ch. 1.14. Owners receive notice and a hearing each spring; if vegetation isn't cleared, the City's contractor abates it and assesses costs against the parcel. On parcels in or adjacent to the LRA Very-High Fire Hazard Severity Zone east of town (Skyway / upper foothills), state law layers California Public Resources Code §4291 on top: 100 feet of defensible space around any structure (Zone 0: 0-5 ft ember-resistant — phasing in; Zone 1: 5-30 ft lean/clean/green; Zone 2: 30-100 ft reduced fuel).

Key details: City code: CMC Ch. 1.14 — Nuisance Abatement. State defensible space: PRC §4291 (100 ft in FHSZ). Zone 0: 0-5 ft ember-resistant (phasing in, AB 3074). Program: Annual lot-clearing & weed-abatement (spring resolution). Contact: Code Enforcement 530-879-6330.

Notice → hearing → City contractor abates → cost recovered as lien on parcel. Re-inspections; failure to maintain after abatement is a misdemeanor under CMC 1.16. State PRC §4291 violations carry administrative fines up to $5,000 per CAL FIRE inspection.

This is not one of those rules that cities tend to ignore. Chico actively enforces its brush clearance requirements.

Outdoor Burning

Open burning of yard waste, vegetation, debris and similar material is prohibited inside Chico city limits year-round, regardless of lot size or burn-day status. The rule is enforced by the Butte County Air Quality Management District (BCAQMD) under its Outdoor Residential Burning rule and by Chico Fire under CMC Ch. 16R.42 (which adopts the California Fire Code). Recreational fires, cooking fires and exempt devices listed in CMC 16R.42.070 (BBQs, fireplaces, gas heating) are still allowed if attended and CFC-compliant. In Chico's unincorporated 'sphere of influence,' residential burning is allowed only on lots of at least 0.90 acre, only on a declared permissive 'burn day,' and only between 8:45 a.m. and one hour before sunset.

Key details: Inside city limits: Open burning prohibited year-round. Sphere of influence: ≥ 0.90 acre; permissive burn day; 8:45a–1h pre-sunset. Burn-day line: 530-332-9407 / bcaqmd.org. Allowed in city: BBQs, fireplaces, gas/wood heaters (CMC 16R.42.070). CAL FIRE permit: Required May 1 onward outside city.

BCAQMD administrative fines starting at $500 and escalating; Chico FD response cost-recovery; CMC 1.16 misdemeanor citation for continuing violations of CMC 16R.42. CAL FIRE PRC §4421/4423 reckless-burning charges if escape occurs.

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