Indianapolis does not have a standalone dark sky ordinance. The city's development standards in Rev. Code Chapter 744 include outdoor lighting provisions for commercial and multi-family development requiring shielded fixtures and limiting light spillover onto adjacent properties. However, there are no specific residential dark sky requirements. Indiana does not have a statewide dark sky law. The city's lighting standards focus on safety and glare reduction rather than astronomical light pollution.
Indianapolis enforces outdoor lighting standards through building codes and zoning regulations. New exterior lighting must use fully shielded (full-cutoff) fixtures that direct light downward. Maximum wattage and lumen limits may apply in residential zones. Motion-sensor lighting encouraged for security. Commercial lighting must not spill onto adjacent residential properties. Parking lot lighting has specific pole height and coverage requirements. Some jurisdictions adopt International Dark-Sky Association recommendations. LED lighting must meet color temperature guidelines, typically 3000K or below to reduce blue light emissions.
Non-compliant fixtures: notice to correct within 30 days. Failure to comply: fines $100 to $500. Commercial violations: permit revocation possible. Repeat offenders: daily fines.
