Ada County has no ordinance banning backyard composting. Home compost piles are allowed, but they must not become a nuisance, attract rodents or vermin, or create odors that interfere with neighbors' use of their property.
There is no county-wide prohibition on residential composting, and no permit is required for a typical backyard pile or bin. The governing limit is the Nuisance Ordinance (Title 5, Chapter 9): a compost operation that harbors rodents, vermin or insects, produces offensive odors, or otherwise interferes with the comfortable use of neighboring property can be treated as a public nuisance. Keep piles contained, avoid meat/dairy that draws pests, and set bins back from property lines. Commercial-scale composting is a different land-use question handled through zoning. Cities may run their own composting or organics programs.
Composting is not itself penalized; a pile that becomes a rodent, odor or vermin nuisance can be ordered abated under the nuisance ordinance, with costs charged to the owner.
