How Franklin Handles Outdoor Lighting: A Practical Guide
Franklin maintains 127 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 Franklin falls on the strict-to-permissive spectrum compared to other cities.
Light Trespass & Shielding
Franklin's zoning code caps light spill: fixtures must minimize glare on neighbors, stay within a 35-degree beam angle, and can't be visible from any residential lot.
Key details: Beam angle limit: 35 degrees from vertical. Residential lots: Light source can't be visible. Citation: Zoning Ordinance § 14.2.2. Effective: January 13, 2026.
Violating any zoning lighting standard is a misdemeanor under Section 22.5, fined per Municipal Code Title 12's general penalty clause; each day a violation continues is a separate offense.
Dark Sky Rules
Franklin's 2026 Zoning Ordinance requires exterior lighting to be shielded and aimed downward, bans fixtures relying only on prismatic or acrylic globes, and requires a photometric plan for site lighting.
Key details: Light source visibility: must not be visible from residential lots. Prismatic/acrylic-only shielding: prohibited. Upward accent lighting: low-wattage architectural only. Photometric plan: required with site plans.
Installing unshielded or improperly aimed lighting violates the Ordinance; the City can require fixture changes, and violations are misdemeanors fined under Title 12, with each day counted as a separate offense.
The Bottom Line
Franklin'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 Franklin is broadly strict or permissive.
