Why your house number placement matters for safety and services

From emergency responders to postal workers, a clearly posted house number is essential for quick and accurate service.

Here’s what Houston, Harris County, and HOAs require for address displays.

The rules governing house numbers in Houston, Harris County, and areas managed by Homeowners’ Associations (HOAs) vary depending on location and jurisdiction.

Posting requirements for house numbers in Houston

The City of Houston requires residential unit numbers to be displayed within 18 inches of the principal entrance, unless otherwise approved by the fire marshal.

Numbers must be at least four inches high, in a contrasting color to their background, and permanently affixed to the structure.

For multi-unit buildings, numbers must also be posted at the ends of each building. If only one end is visible from the street or driveway, numbers are required only on the visible end.

Additionally, noncommercial buildings must have numbers posted where they are plainly visible from the street or driveway, ensuring accessibility for emergency responders and delivery personnel.

Harris County regulations

In unincorporated Harris County and areas within its extraterritorial jurisdiction (ETJ), addressing is overseen by CenterPoint Energy.

Property owners must follow similar visibility standards, but the county emphasizes driveway-based address display for structures on corner lots.

Mailboxes should be placed near the driveway if the address is based on driveway access.

HOA-specific rules

Homeowners’ Associations often impose additional requirements. These may include the mandatory painting of house numbers on curbs or sidewalks to improve visibility.

While not a legal requirement under Houston’s municipal code, this practice is common in HOA-managed neighborhoods.

Residents should consult their HOA guidelines to determine specific compliance standards. In HOA neighborhoods, enforcement may also involve private HOA boards.

Best practices for homeowners

• Ensure house numbers are clearly visible from the street and comply with size and color contrast requirements.
• Confirm with your HOA if curbside painting or other specific guidelines apply.
• Maintain updated address information with local authorities and utilities to avoid confusion during emergencies.
