Dark Skies Standards

(Updated May 2024)

As of February 10, 2024, the adopted Dark Skies Standards by City Council have gone into effect. All new developments in Sisters are required to comply with the City's Dark Skies Standards of SDC Chapter 2.15.2400. The City encourages existing exterior lighting fixtures be progressively replaced with dark-skies friendly options.

What is Dark Skies-Friendly Lighting?

• Light fixtures that are completely shielded and downcast so that the light source is not visible from side view
• Lighting that directed to illuminate only where it is needed
• Lighting that does not cast onto neighboring properties
• Lighting that is only turned on when it needs to be on

Not sure if your lighting fixtures comply?

• Contact a City Planner about the new Dark Skies Standards.
• Submit the Dark Skies Lighting Review Form
