Sierra County, CA Landscaping Rules: Composting (2026)

Sierra County does not prohibit home composting; residents may compost yard and food waste on their own property. Statewide, California's Short-Lived Climate Pollutant law, Senate Bill 1383 (effective January 1, 2022 and administered by CalRecycle), requires jurisdictions to provide organic-waste collection and to divert organics such as plant debris and food waste from landfills, with targets to cut organic-waste disposal substantially. SB 1383 allows jurisdictions to satisfy obligations in different ways, and it provides exemptions or waivers for very low-population and high-elevation areas - relevant to a small, mountainous county like Sierra County - so the exact curbside-organics service available depends on local implementation and any waivers in effect. Backyard composting is recognized as a way residents reduce organic waste under SB 1383. Locally, a compost pile is still constrained by Sierra County Code Chapter 8.20 (Public Nuisances), which lets the County abate anything that is injurious to health or offensive to the senses - so a poorly maintained, odorous, or rodent-attracting pile could be a nuisance. Critically, because Sierra County is bear country, Chapter 8.40 (Black Bear Management and Safety) addresses attractants; compost containing food scraps should be managed (enclosed/bear-resistant where needed) to avoid attracting black bears. Solid-waste handling generally is governed by SCC Chapter 8.04.
