Dark Sky Laws by Jurisdiction

Outdoor lighting law varies widely by state and province: some states have a single statewide dark-sky lighting statute, others regulate only through city or county codes, and Canadian provinces mostly rely on municipal bylaws rather than provincial law. This page tracks the status for all 50 US states and the Canadian provinces and territories, with the underlying statute or code linked wherever one exists, following the same "no unlinked facts" standard used across the site (background on why light pollution is regulated at all is on /learn). If you are a homeowner rather than a policymaker, Dark-Sky Friendly Outdoor Lighting is the practical guide.
