Summary
Alameda's mandatory organic-waste franchise does not reach material a resident composts on the same property where it is generated, whether through backyard composting or on-site anaerobic digestion. A community composting operation stays outside full state permitting only while it keeps under one hundred cubic yards and 750 square feet of feedstock and compost on site at once.
Community composting means any activity that composts green material, agricultural material, food material, and vegetative food material, alone or in combination, and the total amount of feedstock and compost on-site at any one (1) time does not exceed one hundred (100) cubic yards and 750 square feet, as specified in 14 CCR Section 17855(a)(4); or, as otherwise defined by 14 CCR Section 18982(a)(8)... e.Composting. Organic materials composted or otherwise legally managed at the site where it is generated (e.g., backyard composting, on-site anaerobic digestion);

Full Breakdown
Alameda requires every premises to subscribe to organics collection through the city's exclusive franchisee (Sec. 1(b)), but Sec. 3(e) of the franchise chapter carves out an exception for organic materials that are composted, or otherwise legally managed, at the same site where they are generated, giving backyard composting and on-site anaerobic digestion as examples. 8(a) reinforces this for single-family and multi-plex generators, allowing them to manage organic waste by preventing or reducing it, handling it on site, or using a community composting site, so long as other applicable laws are followed.
The code defines community composting by borrowing the state cap in 14 CCR Section 17855(a)(4): a site qualifies only while the total feedstock and finished compost present at any one time stays at or under one hundred cubic yards and seven hundred fifty square feet (Sec. 21-1). A site that grows past that threshold falls out of the community composting definition and into the state's full compostable materials handling facility permitting track instead. Owners of composting operations, including community composting sites, must hand over capacity information to the Waste Management Authority within sixty days of a request, covering estimated organic waste volumes the site expects to process (Sec.
21-4(b)). Nothing in these sections requires a permit, setback, or bin specification for an ordinary residential compost pile that stays on the generator's own property.
Violations & Fines
Composting on your own property is not itself a violation, since Sec. 21-20.3(e) exempts it from the mandatory franchise. But a generator who fails to source separate organic waste when not composting on site, or a community composting operator who exceeds the one-hundred-cubic-yard/750-square-foot cap without obtaining state facility permits, is out of compliance with Chapter XXI and can be cited as an infraction carrying a fine of up to two hundred fifty dollars, in addition to any state enforcement action (Sec. 21-30.2(a)).
