Edmonds, WA Landscaping Rules: Composting (2026)

Edmonds has no separate composting-bin ordinance in the material available; instead, backyard composting is addressed as a carve-out inside the nuisance chapter. 042(C) declares accumulations of perishable matter, including foodstuffs, that may harbor or attract mold, insects or vermin to be a public nuisance capable of enforcement. S. Composting Council, an outside technical body rather than a locally written spec. A resident whose pile is not attracting vermin, is not stagnant, and follows recognized composting practice is not violating this section; a poorly managed pile that draws insects or rodents loses the exemption and can be cited as a health and safety nuisance like any other vermin-attracting accumulation.

042(C)(3)), so a compost setup that also creates standing water or a combustible pile of yard debris around it is not shielded by the compost exemption alone.
