Louisville's Outdoor Lighting: The Rules That Matter

Every city handles outdoor lighting a little differently. In Louisville, Kentucky, there are 2 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Light Trespass

Louisville Metro addresses light trespass through the Land Development Code and nuisance provisions. Commercial and multi-family developments must ensure that lighting does not spill onto adjacent residential properties. The LDC requires lighting plans for new development that demonstrate compliance with foot-candle limits at property lines.

Key details: Standard: Lighting must not spill onto adjacent residential property. LDC Requirement: Lighting plans required for new development. Measurement: Foot-candle limits at property lines. Enforcement: Codes & Regulations and Planning. Complaint: File through MetroCall 311.

Light trespass complaint: warning and 30-day correction period. Non-compliance: fines $100 to $300 per violation. Repeated complaints: escalating fines. Commercial violations: up to $1,000.

Dark Sky Rules

Louisville Metro does not have a comprehensive dark-sky ordinance. The Land Development Code includes some lighting standards for commercial and multi-family development, requiring downward-directed lighting to minimize glare. However, there are no specific dark-sky designations or residential outdoor lighting restrictions beyond general nuisance provisions.

Key details: Dark-Sky Ordinance: None — no comprehensive ordinance. Commercial Lighting: LDC requires downward-directed fixtures. Residential: No specific dark-sky restrictions. Glare Standard: Lighting must not create a nuisance. State Law: Kentucky has no statewide dark-sky law.

Non-compliant fixtures: notice to correct within 30 days. Failure to comply: fines $100 to $500. Commercial violations: permit revocation possible. Repeat offenders: daily fines.

The rules around dark sky rules in Louisville lean permissive, but that does not mean anything goes.

The Bottom Line

Louisville'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 Louisville is broadly strict or permissive.

Keep in mind that Louisville 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.
