Solano County, CA Trash & Recycling: Yard Waste Collection (2026)

Section 23-12 defines green waste as plant material such as leaves, grass clippings, brush and tree cuttings, plus yard trimmings, untreated wood waste and natural fiber products, while excluding treated wood, mixed demolition debris, food material and biosolids. Section 23-20 sets the storage limit: solid waste generally may not accumulate on a lot for more than seven days, and while green waste and recyclable material are given a softer standard, 'removed at a frequency that does not cause a nuisance condition,' the Department of Resource Management, Environmental Health Services Division, can step in after investigation and require more frequent removal of either.

That gives the county case-by-case authority over a pile of brush or grass clippings that starts drawing pests or complaints, rather than a fixed day count. Once put out, green waste has to go into an approved container or be otherwise contained so it does not create a nuisance, per Section 23-21(a). Green waste collection service runs through the same permitted contractor system as regular refuse: Section 23-32 requires anyone who collects green waste for commercial purposes in the unincorporated area to hold a solid waste, recyclables and green waste collection permit issued by the Department, and Section 23-33 requires that permittee to post a minimum $50,000 security bond to guarantee continued service.
