On October 15, 2019, the Cottonwood Heights City Council adopted revised outdoor lighting regulations as part of the City Zoning Code as Chapter 19.77 - Outdoor Lighting

An outdoor lighting checklist for single-family homes has been created to help make the process of compliance straightforward and simple. This checklist does not apply to any other development types.  

Goals for Outdoor Lighting Regulations

Adequate nighttime lighting is important to allow human activity to safely continue after the sun goes down, but inappropriate lighting practices can result in:

•     light pollution 
•     light trespass 
•     glare 
•     poor lighting color increasing glare and affecting human health 
•     poor energy conservation 
•     impact on wildlife and natural ecosystems, and
•     creating skyglow.

These issues can reduce full enjoyment of private property rights, impair human health and safety, waste energy, and create a poor nighttime ambiance. This ordinance provides regulations that seek to mitigate the above noted issues. 

When Does This Ordinance Apply? 

  • All new structures, including new single-family homes. 
  • Any addition to a structure or land use. 
  • Replacing light bulbs. 

Repairing existing light fixtures does not apply.
