Waltham zoning requires shielded outdoor lighting for commercial development and limits light spillover onto adjacent residential properties and public ways.
Waltham does not have a full dark-sky ordinance, but the Zoning Ordinance site plan review requires outdoor lighting in commercial, industrial, and multifamily developments to be full-cutoff or shielded to prevent glare and light trespass. Fixtures must direct light downward onto the property and not onto abutting residential lots or public ways. Parking lot lighting is typically limited to 20 to 25 feet pole height and must shut off or dim after business hours. Building mounted floodlights pointing outward are discouraged. Residential properties have fewer restrictions but must not create nuisance conditions under general nuisance law. Waltham is in the Boston light dome, and uplighting is discouraged citywide. New developments near conservation areas may face stricter review by the Conservation Commission.
