Understanding Building Codes and Regulatory Changes
Building codes are the often overlooked rules that dictate everything from a structure’s foundation to the shingles on a suburban home. When a storm damages property and claims flood in, these codes can be the difference between a smooth settlement and a protracted dispute. They can increase costs, delay payments, and create uncertainty.
Building codes are standardized regulations that establish minimum requirements for construction, design, materials, and safety. Their primary purpose is to protect lives, ensure structural integrity, and reduce the risk of property damage. These codes govern everything from roofing systems to electrical wiring, making them foundational to both the construction and insurance industries.
In the United States, building codes evolve continuously. Updates typically occur every three years, reflecting new safety data, advancements in construction materials, and lessons learned from natural disasters. These updates ensure that structures remain resilient against emerging risks such as hurricanes, wildfires, and flooding.
Understanding this dynamic landscape in the building and roofing industry is crucial. It’s about more than compliance — it’s about risk mitigation, accurate claim valuation, and efficient claims resolution.
Safety concerns, climate change, and technological advancements are the primary drivers behind these updates. For example, increased storm intensity has led to stricter wind-resistance requirements, while wildfire risks have driven mandates for fire-resistant materials. Additionally, innovations in construction technology have introduced new performance standards that older structures may not meet.
Building codes directly influence insurance risk and underwriting decisions. Insurers assess properties based on their compliance with current codes, as non-compliant structures pose higher risks of damage and costly claims. As a result, properties built or upgraded to modern standards often benefit from more favorable insurance terms.
The Role of National Code Frameworks in the U.S.
The International Residential Code (IRC) governs one‑ and two‑family dwellings. The International Building Code (IBC) covers commercial and multi‑family structures. These model codes set baseline standards, but they are only the starting point. Both are developed by the International Code Council and are updated on a recurring cycle, meaning requirements can change significantly within just a few years.
The International Residential Code (IRC) provides guidelines for one- and two-family dwellings. It addresses structural integrity, fire safety, energy efficiency, and mechanical systems, forming the backbone of residential construction standards.
The International Building Code (IBC) governs commercial and multi-family buildings. It includes more complex requirements related to occupancy types, structural loads, fire protection systems, and accessibility standards.
State and local governments often adopt and modify these codes to address regional concerns like high wind loads in coastal areas or specific fire resistance requirements in wildfire‑prone regions. This creates a patchwork of requirements that can differ even within the same state.
Municipalities add another layer, with local amendments, interpretations, and inspection requirements that can vary from town to town. These jurisdiction-specific differences are one of the biggest drivers of claim disputes, as missing even a single amendment can alter the scope and cost of repairs.
States and municipalities adopt these model codes but often modify them to address regional risks. Coastal states may enhance wind-load requirements, while wildfire-prone areas introduce stricter fire-resistance rules.
Because adoption timelines vary, inconsistencies arise across jurisdictions. One state may enforce the latest code edition, while another operates under an older version, creating complexity in claims handling and compliance verification.
Insurers must navigate these variations carefully. Multi-state carriers often rely on specialized tools and regional expertise to ensure accurate claim assessments and compliance with local regulations.
What Is Code Upgrade Coverage (Ordinance or Law Coverage)?
Code upgrade coverage, also known as ordinance or law coverage, is an insurance provision that helps cover the additional costs required to bring a damaged property up to current building codes.
This coverage is typically divided into three parts:
-
Coverage A: Covers the loss of the undamaged portion of a structure when demolition is required.
-
Coverage B: Pays for demolition and debris removal costs.
-
Coverage C: Covers the increased cost of construction due to code upgrades.
While standard policies cover damage from insured perils, they often exclude the additional costs required for code compliance. This creates significant coverage gaps for property owners.
For example, if a roof is damaged and current codes require upgraded materials or installation methods, the additional expense may only be covered if ordinance or law coverage is included.
Without this coverage, homeowners may face substantial out-of-pocket costs, especially in regions with strict or recently updated building codes.
Why Building Code Changes Increase Insurance Claims
Stricter building codes are leading to a rise in claim frequency. As regulations become more comprehensive, more repairs require full compliance, increasing the likelihood of claims being filed and expanded.
Compliance requirements significantly increase repair costs. Even minor damage can trigger upgrades that were not part of the original construction, raising the overall claim value.
Climate-related disasters are accelerating code changes. Hurricanes, wildfires, and floods are prompting regulators to adopt stricter standards, which in turn increase rebuilding costs after a loss.
Litigation trends are also driving stricter enforcement of building codes. Courts increasingly require insurers and contractors to adhere strictly to current regulations, reducing flexibility in claims handling.
As a result, insurers are seeing more supplemental and reopened claims due to missed code requirements or underestimated compliance costs.
Key Statistics and Trends
-
Code-related / Ordinance & Law Claims Increasing
Insurers report a rise in ordinance and law claims as building codes become stricter and more widely enforced (Insurance Information Institute, 2024). - Repair Costs Increase by 20–40% with Code Upgrades
Rebuild costs can increase significantly when properties must meet current building codes following damage (Verisk, 2024 ; FEMA, 2023). - Increase in Catastrophic Weather Events Driving Code Updates
The frequency and cost of extreme weather events are increasing, influencing stricter building regulations (NOAA, 2024 ; IPCC, 2023). - Insurance Premiums Rising Due to Rebuild & Compliance Costs
Insurance premiums are increasing globally due to higher reconstruction costs, climate risks, and stricter compliance requirements (Swiss Re, 2024 ; Munich Re, 2024). - Underwriting Evolving to Include Code Compliance Risk
Insurers are increasingly factoring building resilience and compliance into underwriting and pricing models (AM Best, 2024 ; Deloitte, 2024).
How Code Changes Affect Claim Valuation
Building codes don’t just change for the sake of regulation; they evolve in response to safety data, new materials, and performance standards. When these changes occur, they often impose higher minimum material standards and construction requirements.
For example, updates may require:
- Increased fastener counts for wind uplift resistance
- Expanded use of ice and water shield zones
- Upgraded membrane materials or underlayment standards
These requirements may not have existed when the original structure was built, yet they are required for any repair or replacement following loss. This means adjusters must reference current code requirements when valuing damage, not historic construction standards.
If an adjuster fails to account for updated code requirements, the result can be:
- Underpayment of claims
- Cost disputes with policyholders
- Increased leakage due to correction workloads
Accurate claim valuation depends on a clear understanding of current code requirements and their impact on the scope of repair.
Common Code Updates Impacting Claims
Roofing, in particular, is deeply impacted by code evolution. New materials such as GAF Timberline roofing shingles come with updated performance standards and installation requirements. A roofing contractor who misses a key code detail can cause problems for homeowners and insurers alike.
Roofing and wind uplift requirements often mandate additional fasteners and stricter installation patterns, especially in hurricane-prone and high-wind regions. These updates can significantly increase both labor and material costs, as contractors must follow precise fastening schedules and use approved systems to meet compliance standards. Failure to meet these requirements can result in denied inspections and costly rework.
Fire-resistant materials are increasingly required in wildfire-prone regions, with stricter classifications for roofing assemblies, siding, and decking. These upgrades often involve higher-cost materials such as Class A fire-rated shingles and ember-resistant vents, which can substantially increase claim severity during rebuilds.
Energy efficiency standards now require higher insulation values, improved sealing, and more advanced building envelope systems. This means repairs may involve full system upgrades rather than partial fixes, particularly when insulation, ventilation, or moisture barriers are affected.
Electrical and plumbing upgrades can significantly increase interior claim costs during repairs, especially when older systems must be replaced to meet modern safety standards. This can include updated wiring methods, grounding systems, pipe materials, and fixture requirements.
Accessibility and safety compliance updates may apply in certain jurisdictions, particularly for multi-family or commercial properties. These can include requirements for handrails, egress pathways, ADA compliance elements, and life-safety systems, all of which add complexity and cost to claims.
The High Cost of Code Compliance
Code errors can lead to serious consequences. For example, a roofer who installs shingles that don’t meet local wind resistance requirements may see that roof fails in a storm. Even if the homeowner purchased high‑quality materials, failure to follow local code could make the resulting damage non‑compliant, complicating the claims process and elevating costs.
New regulations often require higher-quality materials and more labor-intensive installation methods, increasing rebuild costs.
Older structures typically cost significantly more to upgrade than modern buildings that already meet current standards. Without proper coverage, property owners face substantial financial risks due to compliance requirements. Hidden costs such as permits, inspections, and engineering reports can significantly increase total claim expenses. Delays caused by compliance verification can extend loss-of-use expenses, adding further financial strain.

Common Mistakes Adjusters Make With Building Code Interpretation
Even seasoned adjusters can fall into familiar traps when interpreting building codes. Some of the most common mistakes include:
- Relying only on IRC/IBC: Not checking for local amendments that have been adopted by municipalities or counties.
- Missing code upgrade costs: Failing to include necessary costs when updated code requirements exceed the historical build.
- Not documenting code references: Field reports without cited code sections make it hard to justify scope decisions.
- Using outdated sources: Relying on printed codebooks or fragmented online pages that are no longer current.
- Assuming historic compliance eliminates upgrades: Just because a structure was compliant at the time of construction doesn’t mean repairs can ignore newer code requirements.
Clear documentation and up‑to‑date code research reduce disputes and improve settlement accuracy.
The Role of Technology in Code Compliance and Claims
Traditionally, adjusters relied on printed code books or fragmented online resources. These sources quickly became outdated, required cross-referencing many volumes, and made it easy to overlook critical requirements.
Manual code research is time-consuming and prone to errors due to constantly changing regulations.
The complexity of navigating multiple jurisdictions, amendments, and code cycles makes manual research inefficient and increases the likelihood of missing critical requirements that directly impact claim accuracy.
