Fire Regulations in Garden Grove, CA

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

Wildfire Zones

Garden Grove is a flat, fully urbanized city in central Orange County and First Street rates citywide wildfire risk as Very Low (about 4% of buildings at any risk). The City has not historically been mapped as containing CAL FIRE High or Very High Fire Hazard Severity Zone (FHSZ) area, so AB 38 disclosure and statewide defensible-space rules generally do not apply. Verify your parcel against the 2025 LRA FHSZ map before relying on this.

Key details: Citywide Wildfire Risk (First Street): Very Low - approx. 4% of buildings at any risk. Topography: Flat urban coastal plain - no wildland interface. FHSZ Status: Not historically mapped High/Very High - verify 2025 LRA map. Map Authority: CAL FIRE / Office of the State Fire Marshal. 2025 Recommended Maps Released: March 24, 2025.

If a parcel is later mapped into a High or Very High FHSZ, owners become subject to PRC 4291 defensible-space requirements, Chapter 7A wildland-urban-interface building standards (CRC R337), and AB 38 seller disclosure at sale; failure to disclose or maintain defensible space can trigger civil penalties, transaction delays, and OCFA enforcement.

Fire Pits & Backyard Fires

Garden Grove's Fire Code amendments regulate outdoor fireplaces, fire pits, and fire rings at homes. Gas-fueled units need Building Department approval and a 3-foot clearance at single-family lots, 10 feet at other residential occupancies; wood-burning units need 25 feet from structures unless built into a permanent fireplace.

Key details: Governing amendment: § 18.16.020, CA Fire Code § 307.6. Gas fire pit clearance (R-3): 3 feet from combustibles. Gas fire pit clearance (other R): 10 feet from combustibles. Wood fire pit setback: 25 feet, or 3-15 ft with spark arrester. Cooking exemption: Barbecues and grills exempt.

Operating a fire pit outside the required clearance, without Building Department approval for a gas unit, or inside a Wildfire Risk Area contrary to Section 307.6.2.1 is enforced under Fire Code Section 113.4, with penalties set by the OCFA Prevention Field Services fee schedule and each day of continuing violation a separate offense. Permitting the hazard to persist after notice can be charged as an infraction, or as a misdemeanor under Section 113.4.2 if the person fails to abate it once ordered by the fire chief or a representative.

Smoke Detectors

Garden Grove enforces California state requirements for smoke detectors and carbon monoxide alarms under the California Health and Safety Code and Building Code. All residential dwellings must have working smoke alarms in each bedroom, outside sleeping areas, and on every level. CO alarms are required in homes with fossil fuel appliances, attached garages, or fireplaces. OCFA inspects compliance during fire safety checks.

Key details: Smoke Alarms Required: Every bedroom, hallway, and level. CO Alarms Required: Homes with gas appliances/garages. Battery Type: 10-year sealed battery or hardwired. State Law: HSC Sections 13113.7 & 17926. OCFA: (714) 573-6000.

Failure to maintain working smoke detectors is a fire code violation enforceable by OCFA. Landlords who fail to provide working alarms face civil liability. OCFA can be reached at (714) 573-6000 for fire safety questions.

Fireworks

Garden Grove bans all fireworks except state-certified "safe and sane" fireworks sold by permitted nonprofit stands. Discharge is legal citywide only on July 4th, 10 a.m. to 10 p.m. Retail sales run July 1st through 4th, and every other sale, possession or use of fireworks is a Municipal Code violation enforced by Code Enforcement and the Finance Department.

Key details: Legal discharge window: July 4th, 10 a.m. to 10 p.m. only. Retail sales dates: July 1st through 4th. Annual stand permit cap: 30 permits citywide. Minimum insurance required: $1,000,000 per occurrence. Buffer from residences: 10 feet minimum.

Fireworks violations are enforced as administrative citations under Chapter 1.22, with fines of $100 for a first offense, $200 for a second violation of the same provision within a year, and $500 for each additional violation within that year (Sec. 1.22.010(F)). The City Manager or law enforcement may immediately seize and dispose of illegal fireworks, and the owner or possessor is liable for the City's actual seizure and disposal costs (Sec. 5.28.180). A stand permit can be suspended immediately or revoked for noncompliance, permit violations, or operations endangering public health or safety (Sec. 5.28.190).

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

Brush Clearance

Garden Grove's Fire Code amendments let the fire code official require clearing flammable vegetation within 10 feet of each side of any highway or private street used for vehicular traffic, measured from the roadway's edge, with an exception for single ornamental trees and green ground cover.

Key details: Governing amendment: § 18.16.020, adding CFC § 325. Clearance zone: 10 feet each side of roadway. Enforced by: Orange County Fire Authority. Exception: Single trees, ornamental ground cover. Penalty basis: CFC § 113.4 / § 113.4.2.

Failing to clear brush within the 10-foot roadway zone after notice is enforced under Fire Code Section 113.4, punishable per the OCFA Prevention Field Services fee schedule, with each day the violation continues treated as a separate offense. Section 113.4.2, added by the same amendment, makes permitting a fire or life safety hazard to exist an infraction, and failing to abate it after an order from the fire chief or a representative a misdemeanor.

Outdoor Burning

Garden Grove's Fire Code amendments ban outdoor wood fires whenever sustained winds exceed 8 mph with humidity under 25%, a red flag condition is declared, or the fire code official posts a warning, and bar any outdoor fire outright once sustained winds pass 20 mph. Rubbish burning is limited to an approved incinerator.

Key details: Governing amendment: § 18.16.020, CA Fire Code § 305.6. Conditional ban trigger: Winds over 8 mph, humidity under 25%. Absolute ban trigger: Sustained winds over 20 mph. Rubbish burning: Approved incinerator only, § 305.7. Enforced by: Orange County Fire Authority.

Burning during a banned wind, humidity, or red-flag condition, or burning rubbish outside an approved incinerator, is enforced under Fire Code Section 113.4, with fines assessed per the OCFA Prevention Field Services fee schedule and each day of continued violation counted as a separate offense. Section 113.4.2, added by the same amendment, treats letting a fire or life safety hazard persist as an infraction, escalating to a misdemeanor if the responsible person fails to abate it once ordered by the fire chief or a designated representative.

This is not one of those rules that cities tend to ignore. Garden Grove actively enforces its outdoor burning requirements.
