The Deadline to Comply With Outdoor Lighting Regulations Is Nov. 15

Permit Applicants Must Demonstrate Full Compliance

In 2003, the Boulder City Council approved an outdoor lighting ordinance to reduce light pollution, promote energy conservation and improve safety and security, including addressing the nighttime lighting needs of an aging population. On Nov. 15, the 15-year period allowing residential, commercial, industrial and mixed-use buildings to come into compliance will end.

Starting Nov. 16, building permit applicants must demonstrate full compliance with the ordinance to obtain a building permit. Additionally, anyone applying for a rental license, for a single-family home or duplex, must also demonstrate full compliance to obtain a license.

Properties not seeking a building permit or owners of a multi-family building seeking a rental license will have one year after the Nov. 15, 2018 deadline before the city will begin enforcement actions.

Compliance will be determined through the submission of a lighting certification signed and stamped (as applicable) by an architect, electrical engineer, electrical contractor or lighting consultant responsible for the plans. Compliance may also be determined by the appropriate licensed design professional or contractor during the final inspection of a project when proposed lighting work is included under the scope of work. A lighting plan may be required for larger discretionary review projects. For rental license applications, compliance will be verified through the rental inspection process.

The outdoor lighting regulations can be reviewed on the city’s website, and property owners can learn how to ensure their outdoor lighting complies with the ordinance by visiting
