Can my Dane County town set its own construction hours?
Yes. Individual towns within Dane County may adopt their own construction noise rules. Check with your town clerk — the county has no blanket curfew to override town-level rules.
What state law covers unreasonable construction noise in rural Dane County?
Wisconsin Statute §947.01 (disorderly conduct) is the fallback for extreme cases — like overnight power tools in a residential area — when no local ordinance applies.
