How Santa Rosa Handles Fire Regulations: A Practical Guide

Santa Rosa maintains 153 local ordinances across all categories, and 5 of those deal specifically with fire regulations. Here is a breakdown of what the city actually requires, what is prohibited, and where Santa Rosa falls on the strict-to-permissive spectrum compared to other cities.

Propane Storage

Santa Rosa exempts small residential-style propane systems from its hazardous materials business plan and permit rules: compressed propane used only for cooking, water heating, or space heating is exempt from CUPA disclosure up to 6,000 cubic feet at standard temperature and pressure; larger volumes or other uses need a full business plan.

Key details: Governing section: § 17-34.060(D)(4). Exempt propane volume: Up to 6,000 cubic feet (STP). Exempt uses only: Cooking, water heating, space heating. Enforcing agency: City's Certified Unified Program Agency. Above threshold: Full Hazardous Materials Business Plan required.

Storing or handling a hazardous material, including propane above the 6,000-cubic-foot exempt threshold, without the required business plan or permit violates Chapter 17-34's CUPA program. The chapter ties enforcement to the City's general penalty provisions in Chapter 1-28, and a permit issued under Section 17-34.050 is non-transferable between owners, businesses, or locations, so a change in operator triggers a fresh CUPA filing rather than an automatic carryover.

Brush Clearance

Santa Rosa's Hazardous Vegetation and Fuels Management Ordinance (ORD-2023-016, City Code Ch. 9-32) requires defensible space on every property in the Wildland-Urban Interface Fire Area (about 9,000 parcels), with specific tree-limbing, hazardous-vegetation removal, and a 5-foot ember-resistant zone. Property owners faced a January 1, 2025 compliance deadline and July 1, 2025 mulch deadline.

Key details: Code section: City Code Ch. 9-32 (ORD-2023-016). Applies to: All ~9,000 parcels in WUIFA. Clearance radius: 100 ft (5/30/100 zones per PRC 4291). Mulch within 30 ft: Restricted; gorilla hair/combustible mulch removed. Invasive removal: Scotch broom, French broom, certain Bay.

If violations persist after a third inspection, property owners are issued a citation. The City may also enter the property and abate the hazard at the owner's expense: costs become a lien against the property under City Code Chapter 9-08 (Weeds and Rubbish) and Chapter 9-32. Continuing violations are separate misdemeanors under City Code § 18-44.110.4 ($1,000 max fine, six months max jail per offense). The Fire Chief has emergency-abatement authority under City Code § 9-08.120 to abate immediately and lien the property for costs.

Fireworks

Possession, sale, gift, storage, or discharge of any fireworks, including 'Safe and Sane', is illegal year-round in Santa Rosa under City Code 18-44.5608.2. Citations carry fines up to $1,000 plus possible misdemeanor jail time.

Key details: Code section: Santa Rosa City Code 18-44.5608.2. Voter mandate: Measure F (after 2003 Lofty Perch Fire). Fine (local): Up to $1,000; misdemeanor. Fine (state): HSC 12677: up to $1,000 + up to 1 year jail. 'Safe and Sane' allowed?: No: all fireworks prohibited.

Violation is a misdemeanor under City Code Section 18-44.110.4, punishable by a fine of up to $1,000 and/or imprisonment not exceeding six months. The Santa Rosa Police and Fire Departments confiscate all fireworks as contraband and may bill responsible parties for fire-suppression costs under Health & Safety Code §§ 13009 and 13009.1. Each day a violation continues is a separate offense.

Outdoor Burning

Open burning of trash, debris, garbage, or hazardous waste is unlawful in Santa Rosa. Vegetative debris pile burning is permitted only for WUI parcels of 5+ acres under a Fire Department permit, and pile burn permits are suspended during the declared wildfire season (annually from approximately June 1 to November 1).

Key details: Open burn (trash/debris): Prohibited year-round. Vegetative pile burn: Permit required; 5+ acre WUI parcels. Pile size: ≤ 4 ft; 50 ft from any dwelling. Clearance: 10 ft around and above pile. Burn hours: 10 a.m.–3 p.m.; out by sundown.

Burning prohibited materials, or burning vegetative debris without a permit, violates City Code Chapter 18-44 and is a misdemeanor under § 18-44.110.4: punishable by a fine of up to $1,000 and/or imprisonment up to six months. The Santa Rosa Fire Department may also recover fire-suppression and emergency-response costs under City Code § 18-44.106.6 (incorporating California Health & Safety Code §§ 13009 and 13009.1), which can run into tens of thousands of dollars when a fire escapes.

Fire Pits & Backyard Fires

Gas-fueled (LPG or natural gas) fire pits are allowed in Santa Rosa with a 10-foot setback from combustible vegetation and overhanging tree limbs. Wood-fueled fire pits are treated as recreational fires under California Fire Code § 307 (adopted at City Code Ch. 18-44): max 3-foot diameter, 25-foot clearance, attendant required.

Key details: Gas fire pit: Allowed; 10 ft from vegetation/overhang. Wood fire pit (residential): ≤ 3 ft diameter; 25 ft from structures. Wood fire pit (non-hosted STR): Prohibited: gas-fueled only. LPG cylinder limit: Single 5-gallon cylinder per STR appliance. Supervision: Attendant + extinguisher required (CFC 307).

Operating a fire pit in violation of City Code Chapter 18-44 is a misdemeanor under § 18-44.110.4, with fines up to $1,000 and/or six months in jail; each day is a separate offense. Short-term rental violations may also be cited under ORD-2021-011 and can lead to STR permit revocation. The Fire Department may recover suppression and emergency-response costs under City Code § 18-44.106.6.

The Bottom Line

Santa Rosa's fire regulations rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Santa Rosa is broadly strict or permissive.

Keep in mind that Santa Rosa can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
