Nashville Zoning Overview

Nashville is a city of approximately 689,447 residents in Davidson County, Tennessee. As the state capital and largest city, Nashville operates under a consolidated metro government and manages land use through a comprehensive zoning ordinance administered by the Metro Nashville Planning Department.

Nashville's zoning framework includes estate-lot single-family zones (RS40, 40,000 sq ft minimum), large-lot single-family zones (RS20, 20,000 sq ft minimum), standard single-family zones (RS10, 10,000 sq ft minimum), compact single-family zones (RS5, 5,000 sq ft minimum), multi-family residential (RM), mixed use limited (MUL), mixed use neighborhood (MUN), mixed use general (MUG), downtown core (DTC), and industrial warehousing (IWD) districts.

Key Zoning Districts

The RS20 district requires 20,000 sq ft minimum lots with 30-foot front setbacks, 10-foot side setbacks, and 25-foot rear setbacks. The RS10 district allows 10,000 sq ft lots with 25-foot front, 5-foot side, and 20-foot rear setbacks. The RS5 district permits 5,000 sq ft lots with 20-foot front, 5-foot side, and 15-foot rear setbacks. All single-family districts have a 35-foot height limit.

Nashville's mixed-use districts (MUL, MUN, MUG) allow varying intensities of residential and commercial development, while the DTC district supports the highest-density development in the downtown core.

ADU Regulations

Nashville allows accessory dwelling units (ADUs) in residential zones. Because Tennessee has no statewide ADU mandate, Nashville's local zoning ordinance governs ADU development. Property owners should contact the Metro Nashville Planning Department at (615) 862-7150 for specific requirements regarding size limits, setbacks, parking, owner occupancy, and design standards.

Development Process

Development in Nashville generally requires obtaining the appropriate permits from the metro 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 Nashville, property owners should:

• Verify the zoning classification of their property
• Review setback, height, and lot coverage requirements
• Check for any overlay districts or urban design overlay (UDO) 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) 862-7150 for pre-application guidance
