Outdoor Lighting in Nashville, TN: What Residents Actually Need to Know

If you live in Nashville or are thinking about moving there, outdoor lighting are one of those things you probably won't think about until they affect you directly. Nashville has 2 specific rules on the books covering different aspects of outdoor lighting, and some of them might surprise you.

Dark Sky Rules

Nashville does not have a comprehensive dark-sky ordinance. Outdoor lighting is addressed generally through the zoning code (Title 17) which requires that commercial and multifamily lighting be directed downward and shielded to reduce glare on adjacent properties. There is no residential dark-sky requirement.

Key details: Dark-Sky Ordinance: None adopted. Commercial Standards: Downward-directed, shielded fixtures required. Residential: No specific lighting restrictions. Code Section: Metro Zoning Code Title 17 (lighting standards). IDA Certification: Nashville is not an IDA community.

Lighting that creates a glare hazard or trespasses significantly onto neighboring properties may be addressed through nuisance provisions or zoning enforcement. There are no specific dark-sky violation penalties.

If you are coming from a city with tighter rules, you will find Nashville gives residents more flexibility on dark sky rules.

Light Trespass

Nashville's zoning code requires commercial, industrial, and multifamily developments to design lighting that does not spill onto adjacent properties. Light trespass from these developments is addressed through site plan review and zoning compliance. Residential light trespass is handled through general nuisance provisions.

Key details: Commercial Standard: Lighting must not spill onto adjacent lots. Review Process: Part of site plan review. Residential: General nuisance provisions apply. Reporting: Metro Codes enforcement. Remedy: Required fixture modification for commercial.

Commercial and multifamily properties that exceed lighting standards face zoning enforcement actions including required modifications to lighting fixtures. Civil penalties may apply for non-compliance after notice.

The Bottom Line

Nashville'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 Nashville is broadly strict or permissive.

Keep in mind that Nashville 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.
