Houston Land Use Overview

Houston is unique among major American cities: it has NO traditional zoning code. With approximately 2,304,580 residents in Harris County, Houston is the largest city in the United States that does not use conventional zoning to regulate land use. Voters have rejected zoning proposals multiple times, most recently in 1993.

How Houston Regulates Land Use Without Zoning

Instead of a traditional zoning ordinance, Houston relies on a combination of regulatory tools:

• Deed Restrictions — Private covenants that run with the land and restrict how properties can be used. The city actively enforces deed restrictions through its legal department. These are the primary mechanism controlling land use in Houston.
• Minimum Lot Size Requirements — The city sets minimum lot sizes: 5,000 square feet for standard residential lots in the inner city (inside the 610 Loop) and 1,400 square feet for townhouse-style development.
• Building Codes — Houston adopts and enforces building codes locally, typically based on the International Building Code (IBC) and International Residential Code (IRC).
• Subdivision Ordinances — Regulate how land is divided and developed, including requirements for streets, utilities, and drainage.
• Setback and Lot Coverage Rules — The city regulates building placement through setback requirements and lot coverage limits.
• Parking Requirements — Minimum parking standards apply to various types of development.
• Height Limits — Height restrictions apply primarily near airports. Otherwise, there are generally no citywide height limits.

Lot Development Standards

Houston's lot development standards establish the basic parameters for residential construction:

• Inner city minimum lot size: 5,000 sq ft (standard residential)
• Townhouse minimum lot size: 1,400 sq ft
• Height limits: Generally only near airports; no broad citywide height limit
• Setbacks and lot coverage: Governed by the city's development ordinances

Secondary Dwelling Units

Houston does not have traditional zoning but allows secondary dwelling units under its lot development standards. Because there is no zoning code per se, the rules for accessory structures are governed by the city's building and development regulations rather than a zoning overlay. Contact the City of Houston Planning & Development Department for current requirements.

Development Process

Development in Houston requires obtaining appropriate permits from the city's planning and building departments. The process typically involves:

1. Deed Restriction Review — Check whether deed restrictions limit the proposed use of your property
2. Lot Development Standards — Verify that your project complies with minimum lot size, setback, and lot coverage requirements
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

Key Considerations

Before starting any development project in Houston, property owners should:

• Check deed restrictions carefully — These are the primary land use control in Houston and are legally enforceable
• Review lot development standards for minimum lot size and setback requirements
• Determine if the property is in a flood zone using FEMA's flood map service — flooding is a significant concern in Houston
• Check for any special districts or management districts that may impose additional requirements
• Review HOA covenants if applicable
• Contact the Planning & Development Department at (832) 394-8854 for guidance
