Chattanooga Zoning Overview

Chattanooga is a city of approximately 181,099 residents in Hamilton County, Tennessee. As one of the state's largest cities, Chattanooga manages land use through a comprehensive zoning ordinance administered by the city's planning department.

Chattanooga's zoning framework includes standard single-family zones (R-1, 7,500 sq ft minimum), compact single-family zones (R-2, 5,000 sq ft minimum), multi-family residential (R-3), convenience commercial (C-2), general commercial (C-3), and manufacturing (M-1) districts.

Key Zoning Districts

The R-1 district requires 7,500 sq ft minimum lots with 25-foot front setbacks, 5-foot side setbacks, and 20-foot rear setbacks. The R-2 district allows 5,000 sq ft lots with 20-foot front, 5-foot side, and 15-foot rear setbacks. Both single-family districts have a 35-foot height limit.

The R-3 district permits multi-family housing including apartments and townhomes, with dimensional standards that vary based on the specific development.

ADU Regulations

Chattanooga allows accessory dwelling units (ADUs). Because Tennessee has no statewide ADU mandate, Chattanooga's local zoning ordinance governs ADU development. Property owners should contact the Planning Department at (423) 643-5900 for specific requirements regarding size limits, setbacks, parking, owner occupancy, and design standards.

Development Process

Development in Chattanooga 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 Chattanooga, property owners should:

  • Verify the zoning classification of their property
  • Review setback, height, and lot coverage requirements
  • Check for any overlay districts or special regulations
  • 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 (423) 643-5900 for pre-application guidance
