Key Zoning Facts
Horn Lake Zoning Overview
Horn Lake is a city of approximately 27,789 residents (2020 Census) located in DeSoto County in northwestern Mississippi, part of the Memphis metropolitan area. The city manages land use and development through its local zoning ordinance, administered by the City of Horn Lake Community Development department.
Horn Lake's zoning code divides the municipality into residential, commercial, and industrial districts, each with specific standards governing permitted uses, lot sizes, building heights, and setback requirements. Mississippi does not enforce a statewide building code, so Horn Lake adopts and enforces building codes at the local level.
Key Zoning Districts
Horn Lake's primary residential districts include R-1 (Single-Family Residential), which requires a minimum lot size of 8,400 square feet with a 30-foot front setback and 35-foot maximum building height; R-2 (Two-Family Residential), allowing duplexes on lots of at least 7,000 square feet with a 25-foot front setback; and R-3 (Multi-Family Residential), permitting multi-family housing on lots of 6,000 square feet or more with a maximum height of 45 feet.
Commercial activity is regulated through the C-1 (Commercial) and C-2 (General Commercial) districts, while industrial uses are directed to the I-1 (Industrial) district. Dimensional standards for commercial and industrial districts vary by use and should be confirmed through the municipal code.
ADU Rules
No specific ADU (Accessory Dwelling Unit) ordinance has been identified in Horn Lake's municipal code. Mississippi does not have a statewide ADU mandate that would override local regulations. Property owners interested in building an accessory dwelling should contact the Community Development department to discuss what may be permitted under current accessory structure regulations.
Development Process
Development in Horn Lake generally requires obtaining the appropriate permits from the city's Community Development department. 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 Horn Lake, property owners should:
- Verify the zoning classification of their property by contacting Community Development at (662) 393-6178
- Review setback, height, and lot coverage requirements for the applicable district
- Check for any overlay districts or special regulations
- Determine if the property is in a FEMA flood zone using the Flood Map Service Center — flood zones apply throughout DeSoto County
- Confirm whether HOA covenants or deed restrictions apply, which are common in Horn Lake subdivisions
- Contact the Community Development department for pre-application guidance
