Summary
Santa Maria does not regulate backyard composting or require a permit for a home compost bin. Santa Maria Municipal Code Section 8-21.04(a) lets single-family households manage their organic waste on-site, including through composting, as an alternative to fully subscribing to the City's mandatory Green Container organics collection service required under the same section.
Shall subscribe to Jurisdiction's Organic Waste collection services for all Organic Waste generated as described below in Section 8-21.4(b). Jurisdiction shall have the right to review the number and size of a generator's containers to evaluate adequacy of capacity provided for each type of collection service for proper separation of materials and containment of materials; and Single-Family generators shall adjust its service level for its collection services as required by Jurisdiction. Generators may additionally manage their Organic Waste by preventing or reducing their Organic Waste, managing Organic Waste on site, and/or using a Community Composting site pursuant to 14 CCR Section 18984.9(c).
Full Breakdown

Violations & Fines
Composting itself carries no penalty under Chapter 8-21 or Section 8-11.20; the risk is letting a pile grow into a nuisance. A compost heap that becomes a menace to health, a fire hazard, or otherwise offensive under Section 8-11.20(a)(3) is treated as an unlawful accumulation, punishable as a general Municipal Code misdemeanor under Section 1-6.01(c), up to $1,000 or six months in jail.
