Franklin, TN Solar Energy: Panel Permits (2026)

Solar permitting in Franklin operates through a federal-state-local framework. (1) Local — building, electrical, and (if applicable) mechanical permits are required through Franklin Building & Neighborhood Services (615-794-7012). Permits are issued under Title 12 (Building, Utility, Etc. Codes), which adopts the codes the state has mandated. Franklin enforces the Tennessee Residential Code (based on the 2018 IRC with state amendments) and the 2017 National Electrical Code (NEC) for PV system wiring, conduit, disconnects, labeling, and grounding. Engineered structural drawings showing roof attachment, wind-load calculations, and racking are typically required for rooftop PV. The contractor must hold a Tennessee general or limited-license-electrical (LLE) classification issued by the Tennessee Board for Licensing Contractors when project value exceeds $25,000 (TCA §62-6-103). Setback, height, and lot-coverage rules in the Franklin Zoning Ordinance (effective 1/13/2026 under Ord. 2025-25) apply to ground-mounted systems. (2) State — Tennessee does NOT have a residential 'solar bill of rights' equivalent to Florida's § 163.04 or California Civil Code § 714 that overrides HOA / deed restrictions, so HOA covenants in Franklin subdivisions can validly restrict or prohibit rooftop solar. Tennessee's 2024 solar legislation (HB 0149 / Public Chapter 936) establishes a regulatory framework for 'solar energy facilities' — meaning utility-scale solar with setback requirements (generally 3.5 times the array width or depth), mandatory decommissioning after 180 days of non-generation, and authority for local legislative bodies to adopt specific regulations. The 2024 law expressly exempts local jurisdictions that already had solar facility regulations in place by July 1, 2025, and the framework does NOT apply to smaller residential solar installations. (3) Utility — TVA, through Middle Tennessee Electric (MTE) which serves most of Williamson County, governs interconnection of behind-the-meter PV under the TVA Dispersed Power Production / Green Power Providers / Generation Partners framework as updated. Net metering / generation buyback terms come from MTE / TVA, not from the city. (4) Federal — the Federal Investment Tax Credit (ITC) of 30% remains available for residential solar through 2032. (5) Fees: Franklin residential building permit fees are set by city fee schedule; PV permit fees typically include structural and electrical components.
