Franklin Zoning Overview

Franklin is a city of approximately 83,454 residents in Williamson County, Tennessee. Located south of Nashville, Franklin is known for its historic downtown and manages land use through a comprehensive zoning ordinance administered by the city's planning department.

Franklin's zoning framework includes agricultural-residential zones (AR, 1-acre minimum), estate-lot single-family zones (RS-40, 40,000 sq ft minimum), large-lot single-family zones (RS-20, 20,000 sq ft minimum), standard single-family zones (RS-10, 10,000 sq ft minimum), multi-family residential (RM), general commercial (CG), and industrial (I) districts.

Key Zoning Districts

The RS-20 district requires 20,000 sq ft minimum lots with 30-foot front setbacks, 10-foot side setbacks, and 25-foot rear setbacks. The RS-10 district allows 10,000 sq ft lots with 25-foot front, 8-foot side, and 20-foot rear setbacks. All residential districts have a 35-foot height limit. The AR and RS-40 districts provide for larger estate-style lots.

The RM district permits multi-family housing including apartments and townhomes, with dimensional standards that vary based on the specific development.

ADU Regulations

ADU regulations have not been confirmed for Franklin. Tennessee does not have a statewide ADU mandate, so any ADU allowances would be governed by the local zoning ordinance. Property owners interested in building an accessory dwelling unit should contact the Planning Department at (615) 550-6740 for current rules.

Development Process

Development in Franklin generally requires obtaining the appropriate permits from the city's planning and building departments. The process typically involves:

  1. Zoning Verification -- Confirm that your proposed use is permitted in the applicable zoning district
  2. Site Plan Review -- For commercial and multi-family projects, submit a site plan for review
  3. Building Permit -- Apply for a building permit with construction documents
  4. Inspections -- Schedule required inspections during construction
  5. Certificate of Occupancy -- Obtain final approval before occupying the structure

For projects that do not conform to existing zoning, property owners may need to seek a variance, special exception, or rezoning through the local board of zoning appeals or planning commission.

Key Considerations

Before starting any development project in Franklin, property owners should:

  • Verify the zoning classification of their property
  • Review setback, height, and lot coverage requirements
  • Check for any overlay districts or historic district requirements
  • Determine if the property is in a flood zone using FEMA's flood map service
  • Confirm whether HOA covenants or deed restrictions apply
  • Contact the planning department at (615) 550-6740 for pre-application guidance
