On January 21, 2021, the City Council enacted Ordinance No. 2021-05, adopting an updated outdoor lighting code.

The outdoor lighting code applies to all new construction. Retrofits to existing outdoor lighting fixtures are not required. However, light bulbs in existing outdoor lighting must be 3,000 degrees Kelvin by December 31, 2024. For more information, please contact planning staff.

The Land Management Code now establishes a maximum of 2,500 lumens (no more than 100,000 lumens per acre) for newly constructed multi-unit dwellings and commercial outdoor fixtures.


Outdoor lighting for new construction must not exceed 3,000 degrees Kelvin. Existing properties must replace light bulbs with bulbs that are 3,000 degrees Kelvin by December 31, 2024.


Outdoor lighting fixtures for new construction must be fully shielded.



Seasonal Lights

Low-lumen seasonal lights that do not cause light trespass or interfere with the reasonable use and enjoyment of property are permitted from November 1 - March 1.

Residential seasonal lights must be turned off by 11:00 PM and must comply with zone-required setbacks.

Commercial seasonal lights must be turned off by midnight.

Low-lumen seasonal lights outlining buildings on Main Street, Swede Alley, and the General Commercial Zoning District are allowed year-round and must be turned off by 2:30 AM.


String Lights

String lights are exempt from the fully shielded requirement and may be used year-round to illuminate decks, porches, and patios, but are prohibited from illuminating landscaping or outlining structures.


Historic Structure Outdoor Lighting

Outdoor lighting fixtures for structures and sites designated historic on the Park City Historic Sites Inventory are exempt from the fully shielded requirement if the fixture emits no more than 400 lumens.
