Summary

Unincorporated Sonoma County requires every single-family, multi-family, and commercial property to subscribe to weekly organic waste collection and sort food scraps and yard waste into the green container.

City-specific rules exist: Petaluma, and Santa Rosa have their own mandatory organics recycling rules that differ from Sonoma County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Generators shall place source separated organic waste, excluding non-compostable paper and textiles, in the green container;(2)Generators shall place source separated recyclable materials in the blue container; and(3)Generators shall place solid waste in the gray container. Generators shall not place materials designated for the gray container into the green container or blue container.

(d) Composting and Recycling Facility Processing Limits. Notwithstanding designation of certain materials as organic waste or recyclable materials under this chapter, generators shall not place materials in the green container or the blue container that cannot be processed by available compost and recycling facilities, as may be determined by agreement between the county and the county's frachisee(s) from time to time. Generators shall be provided with advanced written notice of the same determination.

As of the effective date of this chapter, compostable plastics, manure, biosolids, digestate, sludges, textiles, carpets (whether or not organic), and lumber are not accepted in the green container. Only yard trimmings, food waste, paper products and printing and writing paper may be deposited into the green container as of the effective date of this ordinance. As of the effective date of this chapter, paper products and printing and writing paper may also be placed in the blue container, in addition to other source separated recyclable materials.

Full Breakdown

County Code § 22-3(a) requires owners or occupants of all single-family, multi-family, and commercial premises to subscribe to weekly solid waste, recyclable materials, and organic waste collection from an authorized county franchisee, absent a granted waiver. Section 22-4(c) then requires generators to source-separate organic waste (excluding non-compostable paper and textiles) into the green container, recyclables into the blue container, and everything else into the gray container, and bars putting gray-container material into the green or blue bins. This implements state SB 1383 locally and applies only in the unincorporated county, not inside Santa Rosa, Petaluma, Rohnert Park, Sonoma, or the county's other five cities, each of which runs its own franchise ordinance.

Violations & Fines

First violation draws a written warning; a second violation carries a $100 fine, a third a $200 fine, and each subsequent violation $500, issued as an administrative citation under County Code § 22-24 with a 60-day cure period before penalties are pursued.

Do I have to subscribe to organics collection in unincorporated Sonoma County?
Yes. County Code § 22-3(a) requires weekly organic waste collection service for all single-family, multi-family, and commercial premises unless the county grants a waiver.
What happens on the first organics-sorting violation?
A written warning under § 22-24(e)(1). Fines only start on the second violation ($100), rising to $200 and then $500 for further violations.
