Full Breakdown

1) provides: 'No person shall kindle, conduct, or maintain any burning of grass, weeds, agricultural trimmings, or other combustibles or authorize any such fire to be kindled, conducted, or maintained without a permit as required by the San Joaquin Valley Unified Air Pollution Control District and compliance with all safeguards pursuant thereto. 1 of the California Fire Code (which would otherwise have allowed bonfires up to 5 ft x 5 ft, 50 ft from structures with a fire-official permit) is expressly deleted by the city.

Layered on top, the San Joaquin Valley Air District's Rule 4103 governs open-burning eligibility and 'no-burn' days, and Rule 4901 separately bans residential wood combustion (including in fireplaces and stoves) on declared no-burn days from November 1 through the end of February.

Violations & Fines

Administrative penalties of $500 / $1,000 / $1,500 apply for first/second/subsequent Chapter 1 violations within twelve months (§ 3-1.303(b)). Burning without an Air District permit is also separately enforceable by the SJVAPCD with civil penalties up to $10,000 per violation under California Health & Safety Code § 42402. Modesto can recover its full police, code-enforcement, and fire response costs under § 3-1.305.

Frequently Asked Questions

Can I burn leaves or yard waste in my Modesto backyard?
No. Section 3-1.206 of the Modesto Municipal Code prohibits burning grass, weeds, agricultural trimmings, or other combustibles without a San Joaquin Valley Air Pollution Control District permit, and such permits are limited to agricultural land within city limits. Residential yard-waste burning is effectively banned.
Can I have a bonfire?
No. Modesto expressly deleted Section 307.4.1 of the California Fire Code, the section that would otherwise have allowed permitted bonfires. Combined with the recreational-fire ban in § 307.4.2, there is no lawful path to a bonfire in Modesto outside of a permitted religious ceremony.
What about using my fireplace or wood stove indoors?
Indoor wood burning is regulated by the San Joaquin Valley Air District's Rule 4901, which prohibits residential wood combustion on declared 'no-burn' days from November 1 through the end of February. Check Before You Burn at valleyair.org each day during the burn season.
