McKinney Zoning Overview

McKinney is a rapidly growing city of approximately 195,308 residents located in Collin County, Texas, in the Dallas-Fort Worth metroplex. The city manages land use and development through its local zoning ordinance, which divides the municipality into districts regulating permitted uses, building heights, lot sizes, setbacks, and density.

Note that Texas has no statewide building code. McKinney adopts and enforces its own building codes locally, typically based on the International Building Code (IBC) and International Residential Code (IRC).

Primary Zoning Districts

McKinney's zoning code includes several residential districts with varying density levels. The SF-20 district requires a minimum lot size of 20,000 square feet with setbacks of 30 feet (front), 10 feet (side), and 25 feet (rear), and a maximum building height of 35 feet. The SF-10 district requires 10,000 square foot minimum lots with setbacks of 25 feet (front), 8 feet (side), and 20 feet (rear). The SF-7 district allows 7,000 square foot minimum lots with setbacks of 20 feet (front), 5 feet (side), and 15 feet (rear).

The MF (Multi-Family Residential) district accommodates higher-density housing including apartments and townhouses. Commercial activity is served by the C-1 and C-2 districts, while the I (Industrial) district provides for manufacturing and warehousing uses.

ADU (Accessory Dwelling Unit) Rules

ADU regulations have not been confirmed for McKinney. Texas does not have a statewide ADU mandate. Contact the City of McKinney Planning Department to determine whether accessory dwelling units are permitted in your zoning district and under what conditions.

Development Process

Development in McKinney 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 McKinney, property owners should:

• Verify the zoning classification of their property
• Review setback, height, and lot coverage requirements for their specific district
• 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 (972) 547-7500 for pre-application guidance
