How McKinney Handles Outdoor Lighting: A Practical Guide

McKinney maintains 124 local ordinances across all categories, and 2 of those deal specifically with outdoor lighting. Here is a breakdown of what the city actually requires, what is prohibited, and where McKinney falls on the strict-to-permissive spectrum compared to other cities.

Light Trespass

McKinney prohibits light trespass exceeding 0.5 footcandles at the property line of residentially zoned adjacent parcels. Complaints handled by Code Compliance as a nuisance violation. Aimed flood lights into neighboring yards or windows trigger enforcement.

Key details: Limit: 0.5 fc at PL. Notice: 10-day cure. Fine: up to 500 per day. Classification: Nuisance. Exempt: Porch, vehicle lights.

First warning: 10-day cure. Citation: up to 500 dollars per day. Repeat: Class C misdemeanor.

Dark Sky Rules

McKinney does not have a formal dark-sky designation, but the Zoning Ordinance requires outdoor lighting be shielded and downward-directed in all districts. Commercial parking lot lighting must meet IES full cutoff standards and not exceed 0.5 footcandles at residential property lines.

Key details: Cutoff: Full cutoff over 1,800 lm. Property Line: 0.5 fc max at residential. Canopy: Flat-lens recessed. Sports: Turn-off times required. Dark Sky: Not formally designated.

Contact your local code enforcement office for specific penalty information.

The Bottom Line

McKinney's outdoor lighting rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming McKinney is broadly strict or permissive.

Keep in mind that McKinney can amend these rules at any council meeting. For the most current version of any rule mentioned here, check the specific ordinance page, where we track updates as they happen.
