Key Zoning Facts
Brentwood is a city of approximately 44,807 residents in Williamson County, Tennessee. Located south of Nashville, Brentwood is known for its affluent residential character and manages land use through a comprehensive zoning ordinance administered by the city's planning department.
Brentwood's zoning framework includes estate-lot single-family zones (R-1, 1-acre minimum), large-lot single-family zones (R-2, half-acre minimum), standard single-family zones (R-3, 10,000 sq ft minimum), neighborhood commercial (C-1), and general commercial (C-2) districts.
Key Zoning Districts
The R-1 district requires 1-acre minimum lots with 50-foot front setbacks, 20-foot side setbacks, and 40-foot rear setbacks. The R-2 district allows half-acre lots with 35-foot front, 15-foot side, and 30-foot rear setbacks. The R-3 district permits 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.
ADU Regulations
ADU regulations have not been confirmed for Brentwood. 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) 371-0060 for current rules.
Development Process
Development in Brentwood generally requires obtaining the appropriate permits from the city's planning and building departments. The process typically involves:
- Zoning Verification -- Confirm that your proposed use is permitted in the applicable zoning district
- Site Plan Review -- For commercial and multi-family projects, submit a site plan for review
- Building Permit -- Apply for a building permit with construction documents
- Inspections -- Schedule required inspections during construction
- 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 Brentwood, 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 (615) 371-0060 for pre-application guidance
