Dallas Building Codes and Insurance Repairs

When hail, wind, fire, or water damages a Dallas home or business, the repair has to meet the building codes in force today, not the codes that applied when the building went up. That is true for a 1920s Craftsman in the M Streets, a 1960s ranch in Lake Highlands, and a 2010s office building off the Tollway alike. The gap between how a building was built and how it must be rebuilt is one of the most common sources of confusion on insurance claims. This page summarizes Dallas building codes and how they relate to insurance repairs, using information published by the City of Dallas Planning & Development Department on dallascityhall.com.

Overview: Dallas enforces the 2021 ICC codes

According to the City's Current City Codes and Ordinances page, "2021 International Code Council codes are effective as of May 12, 2023." Each model code is adopted into its own chapter of the Dallas City Code with local amendments, so the Dallas version can differ from the ICC model text. The ordinance adopting the 2021 International Residential Code states that it takes effect on May 12, 2023. The fire code took effect a little earlier, on February 10, 2023, and the electrical code follows its own cycle.

As of our last review, the City had not posted an adoption of the 2024 ICC codes. When it does, the edition and effective date on this page will change, which is one more reason to check with the City before a project starts.

Adopted codes

A note on the electrical code: the City's code list still describes Chapter 56 as the 2020 National Electrical Code, but the City's April 2025 letter to electrical contractors states that City Council adopted the 2023 NEC on April 23, 2025, with an effective date of May 23, 2025. That letter also notes an administrative policy that service conductors or equipment damaged by accident, fire, or storm conditions such as ice or falling tree limbs may be restored to their original safe condition without upgrading to the minimum size required for new services. Ask the electrical inspector how that applies to your situation.

Roofing repair and replacement in Dallas

Roofs are where building codes and insurance claims meet most often in Dallas. Hail is the most frequently reported severe weather in the NOAA record for Dallas County, and most homes here have composition shingle roofs over brick veneer, while apartments, retail centers, and warehouses often have flat or low-slope TPO or modified-bitumen roofs. When a roof is replaced after hail or wind, the work needs a permit and must meet the roofing provisions of Chapter 9 of the Dallas One- and Two-Family Dwelling Code (the 2021 IRC as amended) or the roofing chapter of the Dallas Building Code for commercial buildings.

Dallas's IRC amendments include a few reroofing-specific rules. The amended Section R908.1 requires that materials and methods used to recover or replace a roof covering comply with Chapter 9, and that individual replacement shingles comply with the roof classification requirements of Section R902.1. The same section exempts reroofing from the minimum one-quarter-inch-per-foot design slope, and from adding secondary overflow drains or scuppers, when the roof provides positive drainage. Dallas also amended the "roof recover" rules that govern when a new covering may go over an existing one, which affects whether a tear-off is required.

Insurer estimates sometimes price the visible roofing material but leave out items that a permitted, code-compliant installation requires, such as proper underlayment, drip edge, starter and ridge components, flashing, debris disposal, and the permit fee itself. Whether those items are owed depends on whether they are part of repairing covered damage under your policy and on any ordinance or law coverage. For more, see roof damage insurance claims, Dallas hail damage claims, and how to review an underpaid roof insurance estimate.

Wind-resistant construction

Dallas County sees severe straight-line winds as well as tornadoes. The NOAA record includes a 115 mph gust measured at Addison Airport on June 14, 1996 (NCEI), winds up to 95 mph in Garland on May 28, 2024 (NCEI), and the EF3 tornado that crossed northwest and north Dallas on October 20, 2019 (NCEI). Wind requirements come from the adopted IRC and IBC and the standards they reference, which assign design wind speeds by location and risk category. We do not list a design wind speed here; your designer, contractor, or Planning & Development can confirm the value for a particular project.

One point causes frequent confusion: TDI windstorm certification applies only within the Texas Windstorm Insurance Association catastrophe area along the coast. Dallas County is not in the TWIA area, so Dallas properties typically get wind and hail coverage from their regular insurer (or the Texas FAIR Plan where applicable), and TDI windstorm certification does not apply.

Permit requirements

Chapter 52 of the Dallas City Code lists the work that does not need a building permit. Everything else generally does. Key points for insurance repairs:

• Roof replacement needs a permit. Only reroofing of two roofing squares or less is exempt, so a small patch may not need one, but a hail replacement will.
• Some exterior work is exempt. The no-permit list includes adding storm windows, screens, shutters, rain gutters, or insulation, and adding trim or siding to single-family or duplex homes.
• Finish work is exempt. Painting, wallpaper, paneling, floor coverings, cabinets, moldings, and countertops do not need a building permit, and neither does interior remodeling of non-load-bearing parts of a single-family or duplex home that does not add floor area.
• Trade work is separate. Electrical, plumbing, and mechanical work has its own permit rules in Chapter 52. That matters after fire and water losses, when walls are opened and systems are replaced. Exempt building work does not make the related trade work exempt.
• Remodel paperwork. The City's residential permit page offers a General Repair Scope of Work form and a remodel checklist, which are useful references when a loss affects several rooms.

Planning & Development notes that many services cannot be completed online in DallasNow, and its Permit Center helps customers in person. Permit costs for covered repairs are often part of a complete repair estimate. Keep copies of permits, inspection results, and fee receipts in your claim file.

Structural repairs

Tornadoes, fallen trees, fire, and long-term water damage can affect framing, trusses, walls, and foundations. Structural repairs require permits, may require engineering, and must meet current code. Dallas's mix of slab-on-grade homes and older pier-and-beam houses in neighborhoods like Lakewood, Lower Greenville, and Oak Cliff means structural repairs can look very different from one street to the next. Rebuilding to current standards can cost more than restoring the original construction, which is where ordinance or law coverage becomes important. Because the International Existing Building Code is part of the adopted package, the extent of required upgrades during repairs may depend on the scope of the work; confirm with Planning & Development.

Foundation movement on expansive Blackland Prairie clay is a separate issue. Many policies exclude settling and earth movement unless it is caused by a covered peril, such as a plumbing leak, so check your policy before assuming a foundation repair is part of a claim.

Code-related upgrades

Code-related upgrades are items that are not "damaged" in the usual sense but must be added or changed because the repair triggers current requirements. Examples can include electrical updates when walls are opened, smoke alarm requirements tied to permitted interior work, energy code items when insulation is replaced, or roofing components required by the amended IRC. Some upgrades apply only when certain thresholds are met. Ask Planning & Development or a licensed contractor which upgrades your project requires, and get that in writing where possible.

Inspections

Permitted work is inspected in stages, ending with a final inspection. For reroofing, the City will not approve the final until proof of debris disposal is submitted, and the building official may require special inspections. Inspection results and any correction notices are useful claim documents because they show what the City actually required on the job. If an inspector requires an item the insurer's estimate left out, that correction notice is strong support for a supplement.

Contractor responsibilities

In most projects the contractor pulls the permit, builds to code, and schedules inspections. Dallas requires contractors to be registered with the City. Before work starts, ask your contractor to confirm the permit, explain which code items are included in the price, and itemize code-required work separately from like-kind repairs. That separation makes it easier to present code items to your insurer. In Texas, a public adjuster may not take part in repairing a property on a claim they adjust, so your contractor and your public adjuster play different roles.

Ordinance or law coverage

Ordinance or law coverage pays, up to its limit, for increased costs to comply with building codes when repairing covered damage. It is often a separate, limited coverage or an endorsement, and the limit may be a percentage of the dwelling coverage or a fixed dollar amount. Some policies have little or none. Check your declarations page and policy forms, and note that some policies pay code-upgrade costs only after the work is actually completed. Our article on building codes and insurance repairs in Dallas explains this in more depth.

Suburbs have their own building offices

The City of Dallas codes and permits apply only inside Dallas city limits. The surrounding cities are separate jurisdictions with their own building inspection and permit offices, adopted code editions, local amendments, fees, and inspection procedures. That includes Highland Park and University Park, which are surrounded by Dallas, as well as Richardson, Garland, Irving, Mesquite, Carrollton, Grand Prairie, Plano, and Rowlett, plus Addison, Farmers Branch, Coppell, DeSoto, Cedar Hill, Duncanville, Lancaster, and other nearby cities. A roof replacement in Plano or a fire rebuild in Garland follows that city's rules, not Dallas's. If you are not sure which city you are in, check your property tax statement or ask the city.

Code-related claim disputes

Disagreements often involve whether a code item was required, whether it relates to covered damage, or whether the policy includes enough ordinance or law coverage. Helpful steps include:

• Get written confirmation of the requirement from Planning & Development (or your city), an inspector, or a licensed professional.
• Ask your contractor to itemize code-required work.
• Compare the insurer's estimate line by line with the permitted scope.
• Submit a supplement with the documentation, or request an independent estimate review.

If the dispute is over the amount of loss, your policy's appraisal clause may apply. For coverage disputes or legal deadlines, consult a Texas attorney.
