Summary
Union City lets residents pile leaves, grass clippings and similar yard debris for backyard composting or mulching, exempting that material from the citywide ban on storing solid waste on private property.
Storage Prohibited—Private Property. Other than as herein set forth, it is unlawful for any person to dump, bury, or otherwise dispose of or store or accumulate any solid waste on any private or public property within the City, provided, however, that leaves, grass clippings, and the like may be permitted for the purpose of backyard composting or mulching.

Full Breakdown
Union City Municipal Code § 7.04.070(E) makes it unlawful to dump, bury, store or accumulate solid waste on private or public property, but it carves out one exception: leaves, grass clippings and similar yard debris may be kept for backyard composting or mulching. The code sets no permit requirement, container standard, or size limit for that pile, it's a bare exemption from the general storage ban, not an affirmative composting program. Anything beyond yard trimmings, like food scraps mixed with regular trash, still falls under the City's normal solid waste and organic waste collection rules in this chapter.
Violations & Fines
Storing yard debris beyond what qualifies as backyard composting, or storing other solid waste on the property, is an unlawful storage violation under § 7.04.070 and enforceable through the general penalty, § 1.16.010 (up to $1,000 fine as a misdemeanor).
