Denver addresses light trespass through the Denver Zoning Code Article 10, Division 10.8 (Outdoor Lighting Standards) which limits the amount of light that may spill onto neighboring properties. Light trespass complaints can be filed through Denver 311 and are investigated by zoning enforcement.
The Zoning Code establishes maximum foot-candle levels at property lines that vary by zone district. Residential zone boundaries have the lowest allowable light levels. All new exterior lighting fixtures must be fully shielded to direct light downward and prevent off-site glare. Security and parking lot lights must use full-cutoff fixtures aimed at the property rather than toward neighbors. Existing properties that generate light trespass complaints may be required to adjust or shield fixtures even if installed before current standards. The Denver Zoning Code prohibits light that unreasonably interferes with neighboring properties.
Light trespass complaints are investigated by Denver zoning enforcement. Initial response is typically a notice to abate requiring the property owner to adjust or shield lighting. Non-compliance after notice can result in fines. Persistent light trespass may also be addressed as a nuisance under general municipal code provisions.
