Castle Rock is not a formal certified Dark Sky community, but Chapter 17.58 of the Zoning Code (Illumination) regulates outdoor lighting. Fixtures generally must be shielded and directed to limit glare and light spilling onto neighboring properties. There is no county-level rule; the Town regulates lighting inside town limits.
Castle Rock's outdoor lighting standards are in Chapter 17.58 (Illumination) of Title 17 zoning. The Town has no separate 'dark sky' ordinance certification, but its illumination standards require lighting to be designed and shielded so it does not create glare or trespass onto adjacent parcels or public streets, particularly for commercial and multifamily development. Sign illumination is separately governed by the Sign Code (Chapter 19-04-054). Residential fixtures should be aimed downward and shielded as a good-neighbor practice. Confirm project-specific standards with the Development Services/Planning Division.
Lighting that violates the illumination standards can be cited as a zoning violation, with orders to shield, redirect, or reduce the fixture.
