Houston's Hurricane Preparedness: The Rules That Matter

Every city handles hurricane preparedness a little differently. In Houston, Texas, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Hurricane Shutters

Houston's building code requires impact-resistant glazing or approved hurricane shutters in wind-borne debris regions. The Texas Department of Insurance enforces windstorm standards in designated coastal counties, and parts of Harris County are in the TWIA territory.

Key details: Code: 2021 IBC / IRC. Test Standards: ASTM E1886 & E1996. TWIA Certificate: WPI-8 required. Enforcement: TDI / Local inspectors.

Non-compliant windows may disqualify a property from TWIA windstorm insurance. Building permit may be denied without proper glazing protection. Insurance claims can be reduced for non-code-compliant openings.

Roof Standards

Houston's building code requires roof systems to resist wind loads per ASCE 7-16 design standards. Roof-to-wall connections must use hurricane clips or straps, and roofing materials must be rated for the local design wind speed.

Key details: Design Wind Speed: 130 mph (Risk Cat II). Standard: ASCE 7-16. Roof-Wall Connection: Hurricane clips/straps. Sheathing Nailing: 6" edges / 12" field.

Failure to meet wind resistance standards results in building permit denial. Non-compliant roofs may void windstorm insurance coverage. After storm damage, repairs must bring the roof up to current code standards.

Flood Elevation

Houston's Chapter 19 Floodplain Ordinance, amended after Hurricane Harvey in 2018, requires new construction in the 500-year floodplain to be elevated 2 feet above the 500-year flood elevation — significantly stricter than federal NFIP minimums.

Key details: Code Section: Chapter 19. Elevation Std: 2 ft above 500-yr BFE. Effective: September 1, 2018. Slab-on-Grade: Banned in 100-yr floodplain.

Building without proper elevation permits: stop-work order and fines. Non-compliant structures may be denied flood insurance or charged significantly higher premiums. The city can require retroactive compliance for unpermitted construction.

This is one of the stricter rules in Houston's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

Storm Debris

Houston's Solid Waste Management Department coordinates storm debris pickup under Chapter 39. Residents must separate debris into six categories and place it curbside at least 5 feet from obstructions for collection.

Key details: Code Section: Chapter 39. Categories: 6 types of separation. Placement: Curbside, 5 ft from obstacles. Department: Solid Waste Mgmt (SWMD).

Improperly separated debris may not be collected. Placing debris in the street rather than curbside can result in citations. Illegal dumping fines up to $4,000 per occurrence.

The Bottom Line

Houston's hurricane preparedness rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Houston is broadly strict or permissive.

These rules come from Houston's publicly available municipal code. For complete penalty schedules, exemption details, and answers to common questions, see the individual ordinance pages throughout this guide.
