Dark Sky Ordinance Details

The city of Boulder originally passed this ordinance in 2003.  Any property that has gotten a building permit since then most likely has complied but staff understood that there were significant properties not in that category that may not be aware of the law. The law went into effect November of 2018, with enforcement starting in November of 2019.

This ordinance requires exterior lighting to meet “brightness” standards that move to eliminate light pollution. Exterior lighting will have to ultimately be replaced if lights shine upward and/or glass enclosures release light pollution that exceeds the standards set forth in the ordinance (equivalence to a 60 watt bulb). See links below for more information.

If you are renting a condo, no worries.  Thanks to BARHA, staff now understands that in a condo situation most folks do not have control over the exterior lighting. So if you do not have control over it, you are not responsible for it.  If you are a member, please email and call and let me know if you have questions.  We are happy to help.  If you are not a member, JOIN NOW!!
