Full Breakdown

59 to add a list of local operational permits, and item 5 covers bonfires and rubbish fires: no one may kindle, or authorize the kindling or maintenance of, a bonfire or rubbish fire anywhere in the City of Sonoma without first obtaining a permit from the Bureau of Fire Prevention. 1. 035 adopts the California Wildland-Urban Interface Code and directs the fire department to maintain a current VHFHS zone map, so anyone considering an open fire near mapped wildland areas is doubly on notice. A homeowner planning a backyard bonfire, a business hosting an outdoor event with an open flame, or anyone burning rubbish must clear it with the Bureau first; skipping the step is treated the same as skipping any other required fire-safety permit under the code.

010, the citywide violation-penalty section, which lets code enforcement officers issue infraction citations. 10 violations specifically draw a $100 fine for a first offense, $500 for a second violation of the same section within a year, and $1,000 for a third or subsequent violation within a year, rather than the lower general infraction fines used elsewhere in the code. 010(E) bars the city from issuing any building, zoning, or fire permit to a responsible party until penalties and fees tied to the violation are paid.

Violations & Fines

Kindling a bonfire or burning rubbish without a Bureau of Fire Prevention permit is a Chapter 14.10 SMC violation, punishable as an infraction: a $100 fine for a first offense, $500 for a second violation of the same section within a year, and $1,000 for a third or subsequent violation, per SMC § 1.12.010(A)(4). Each day the violation continues is a separate offense, and the city may withhold other permits until fines are paid.

Frequently Asked Questions

Do I need a permit to have a bonfire in the City of Sonoma?
Yes. SMC § 14.10.040, amending California Fire Code § 105.5.59, requires an operational permit from the Bureau of Fire Prevention before kindling or maintaining a bonfire or rubbish fire anywhere within city limits. The rule covers backyard fires and open burning of rubbish alike; there is no size exemption printed in the section, so check with the Bureau before lighting one.
What happens if I burn without a permit?
It's enforced as a Chapter 14.10 SMC infraction under SMC § 1.12.010: a $100 fine for a first offense, $500 for a second violation of the same section within a year, and $1,000 for a third. Each day the violation continues counts separately, and the city can hold up other permits you need until the fine is paid.
Who issues bonfire permits in Sonoma?
The Bureau of Fire Prevention, part of the Sonoma Valley Fire District Prevention Bureau created under SMC § 14.10.040 subsection 103.1. Permit fees are set by the Fire District's adopted fee schedule under subsection 105.1.1.1, so cost varies with whatever schedule is current when you apply.
