Castle Rock's zoning Illumination standards (Chapter 17.58) require outdoor lighting to be shielded and directed so it does not cast glare or spill light onto adjacent properties or public streets. Excessive light onto a neighbor can be addressed as a zoning-code and nuisance matter through Town Code Compliance.
Under Chapter 17.58 (Illumination) of the Zoning Code, exterior lighting must be designed and shielded to prevent glare and light trespass beyond the property, with the tightest requirements applied to commercial, industrial, and multifamily sites. Persistent light spilling onto a neighboring home can also be treated as a nuisance under the Town's public-peace provisions. Residents should first ask a neighbor to redirect or shield a fixture; unresolved issues can be reported to Code Compliance. Sign lighting is governed separately by the Sign Code.
A fixture causing glare or trespass in violation of Chapter 17.58 can prompt a correction notice requiring shielding or redirection; unresolved cases escalate through Code Compliance.
