Corpus Christi Building Codes & Insurance Repairs

After a hurricane, hailstorm, or fire, a damaged building in Corpus Christi has to be repaired to the codes in force today, not the codes it was originally built under. On the coast, that also means meeting Texas Department of Insurance (TDI) windstorm requirements so the property stays eligible for Texas Windstorm Insurance Association (TWIA) coverage. This guide explains Corpus Christi building codes for insurance repairs, what the city requires for re-roof permits, how WPI-1 and WPI-8 forms fit in, and how ordinance or law coverage can affect what your insurer pays.

Codes adopted by the City of Corpus Christi

The City of Corpus Christi adopted a new set of construction codes, with local amendments, effective August 1, 2023, according to the city's construction codes and ordinances page. The codes are found in Chapter 14 of the City Code.

One detail surprises people: the energy code is the 2015 edition of the International Energy Conservation Code, not the 2021 edition. The city's adopting ordinance states this in Section 1.2. Energy code provisions can matter on an insurance claim when replacing items such as insulation, windows, or HVAC equipment.

Local wind design criteria

The ordinance includes the local version of IRC Table R301.2, the climatic and geographic design criteria that guide residential construction. It lists:

• Design wind speed: 140/150 mph
• Windborne debris zone: Yes
• Termite risk: Very High
• Elevation: 19 ft

Being in a windborne debris zone typically affects requirements for protecting glazed openings such as windows and doors, and the wind speed drives fastening, connection, and component ratings. Termite risk can come up when framing or wood is exposed during repairs.

Corpus Christi Development Services

Permits, plan review, and inspections are handled by the city's Development Services department:

• Address: 2406 Leopard Street, Corpus Christi, TX 78408
• Mailing address: P.O. Box 9277, Corpus Christi, TX 78469
• Phone: (361) 826-3240; fax (361) 826-3006
• Online permits: the Dynamic Portal, used to apply for permits, pay fees, and schedule inspections (first-time users create an account). Forms are at dsforms.cctexas.com.

Re-roof permits and the WPI-1

Re-roofing requires a permit in Corpus Christi. According to the city's residential remodels and repairs page, the roofing and siding submission includes:

1. The Residential Building Permit Application (Form 1003)
2. A detailed scope of work naming the roofing method and materials
3. A completed TDI WPI-1 form from the windstorm engineer or inspector responsible for windstorm compliance

The city's homeowner permitting guide describes re-roofing as replacing existing roof coverings and lists these items as needing a permit: replacing more than 100 square feet of shingles, changing the roof slope, removing and replacing roof decking, and changing the roof material.

The same remodel page notes that windstorm-related repairs, including interior remodeling and foundation repairs, require an engineer, and that new accessory construction requires a sealed windstorm plan. And the city's local amendment (Section 110.3.4.1) says framing inspections "do not include or take the place of inspections or certifications for compliance required under Texas Department of Insurance windstorm requirements."

For insurance claims, these requirements are real costs of the repair. Permit fees, engineering or windstorm inspection fees, and any work required to pass inspection may belong in the estimate, depending on the policy. Our roof damage insurance claims page and our guide on how to review an underpaid roof estimate explain how to check for them.

The TDI windstorm program and WPI-8 certificates

The TDI Windstorm Inspection Program was created by House Bill 2012 in 1987, and TDI inspections began January 1, 1988. It applies in the TWIA designated catastrophe area, which includes Nueces, San Patricio, Aransas, and Kleberg counties, and the covered work includes "re-roofs or roof repairs." Inspections are performed by appointed Texas-licensed professional engineers or TDI inspectors.

Under Texas Insurance Code Section 2210.251, structures built, altered, remodeled, enlarged, or repaired, or with additions, on or after January 1, 1988 need a certificate of compliance to be eligible for TWIA coverage. TDI issues the WPI-8 and WPI-8-E certificates, and TWIA issues the WPI-8-C. TDI took over issuing certificates for completed improvements on June 1, 2020.

Starting April 1, 2026, TDI requires windstorm certificate of compliance applications (WPI-1) to be certified to the 2024 International Residential Code or 2024 International Building Code, according to TDI's adopted windstorm codes page. As TDI puts it, "Construction must be certified to be eligible for windstorm insurance coverage through TWIA." That means a Corpus Christi re-roof may need to satisfy the city's 2021 codes for the permit and TDI's 2024 codes for the windstorm certificate.

Ordinance or law coverage

A common misconception is that if the code requires something, the insurer must pay for it. That is not how most policies work. Code requirements alone do not create coverage. Instead, many policies include ordinance or law coverage, sometimes as an endorsement, that pays up to its limit for the increased cost of complying with codes when repairing covered damage. The limit is often a percentage of the dwelling coverage or a fixed dollar amount, and some policies do not include it at all.

Examples where ordinance or law coverage may come up in Corpus Christi:

• Upgraded fastening, underlayment, or roof-to-wall connections needed to meet the 140/150 mph design wind speed
• Impact-rated windows or opening protection in the windborne debris zone
• Replacing undamaged portions of a system because the code does not allow a partial repair
• Engineering and windstorm certification work required for TWIA eligibility

Whether these are paid depends on the policy wording, the limit, and whether the underlying damage is covered. Some policies also require that the work actually be completed before the code-upgrade portion is paid. If your insurer's estimate leaves out code-required items, document the requirement (an inspection note, the permit conditions, or the specific code section) and ask the insurer to consider it under ordinance or law coverage. Our insurance estimate review and claim supplements pages explain that process, and our article on replacement cost vs. actual cash value covers how depreciation and holdback payments interact with repairs.

Other Coastal Bend communities

The city codes above apply inside Corpus Christi city limits, including North Padre Island. Portland, Rockport, Port Aransas, Aransas Pass, Ingleside, Robstown, Kingsville, and unincorporated Nueces County set or administer their own rules, so check with that jurisdiction's building office. The TDI Windstorm Inspection Program applies throughout the catastrophe area regardless of city. See our areas we serve page for local notes.

How a public adjuster uses code information

Corpus Christi Public Adjuster reviews your policy's ordinance or law limit, identifies code and windstorm requirements that apply to the repair, and includes them in an itemized estimate with supporting documentation. We are not code officials, engineers, or attorneys, and we do not make code determinations; we rely on the city, TDI, and your licensed contractor and engineer for that. For disputes involving lawsuits or deadlines to sue, consult a Texas attorney.

Fees are disclosed in a written contract before any work begins; Texas law caps public adjuster compensation at 10% of the insurance settlement. If code items are missing from your claim, request a Free Claim Review or call or text +1 (832) 503-5866. As your Corpus Christi Public Adjuster, we can help you present those costs clearly.
