Yellowstone County has no ordinance banning backyard composting. Residents may compost yard and food waste; keep piles from becoming a rodent, odor, or vector nuisance. RiverStone Health oversees general sanitation and vector concerns.
Backyard composting of yard trimmings and kitchen scraps is allowed in unincorporated Yellowstone County; there is no county permit or prohibition for a home compost pile or bin. The main constraint is general public-health and nuisance law: a pile that attracts rodents, produces strong odors, or breeds insects can be treated as a sanitation nuisance. RiverStone Health, the Yellowstone County health department, handles vector control and sanitation complaints. Inside the City of Billings, standard nuisance and solid-waste rules apply, so keep compost contained and turned. Do not compost meat, dairy, or diseased material in open piles to avoid attracting wildlife and rodents.
No county penalty for ordinary composting. A pile that becomes a rodent harborage, odor, or vector nuisance can draw a health/sanitation notice from RiverStone Health or, in Billings, city code enforcement.
