Understanding Park City’s Goals for Outdoor Lighting

Pollution of our natural environment is not limited to daytime hours only. Light pollution hinders access to viewing the starry night sky along the Wasatch Back, and has negative impacts on our area's beloved wildlife, our mental health, and more. This is why your local leaders have committed to encouraging dark sky-friendly lighting practices!

Help save our night sky!

Per the Land Management Code, by December 31, 2024, all outdoor light bulbs in Park City must be 3,000 degrees Kelvin or less. Properties in unincorporated Summit County also have requirements to comply with dark sky lighting this year.

With the compliance deadline approaching, the City and County are partnering on educating our community about the importance of dark sky-friendly lighting and how to ensure your home and business are up to code. This effort includes supporting and promoting other organizations and events that relate to dark skies education.

Get your lighting in check!

  • Select outdoor lighting fixtures that are fully shielded and pointing downward.
  • Replace yard lighting with shielded fixtures and bulbs within brightness limits, and use only when needed to eliminate extreme glare, excess light, and light spillage (also called "light trespass") over a wide area.
  • Install warm white or extra warm white bulbs (3,000K maximum) instead of daylight, cool white, or white, non-compliant bulbs.
  • Use dimmers, timers, or motion sensors on fixtures and program them for efficiency.
