A partial fire loss to a commercial building can trigger requirements that go far beyond the original damage. In many cases, the entire structure may need to be brought up to current building codes before reconstruction can begin. 

For older commercial buildings, the difference between what a standard property policy pays and what those codes require can become a major uninsured cost.

Building code upgrade coverage, also called ordinance or law coverage, is an insurance endorsement (a policy add-on) designed to fill that gap. Knowing how it works, and where its limits may fall short, matters for any commercial property owner insuring an aging asset.

Key takeaways: How building code upgrade coverage affects commercial property owners

The points below cover what this endorsement does, and what factors may affect whether coverage stays adequate over time. Both views help owners gauge whether their current protection matches their actual exposure.

What property owners need to know

Three points cover what this endorsement does and does not do:

• Standard commercial property policies often do not fully cover the extra cost of meeting current building codes, though some include limited built-in ordinance or law protection.
• The endorsement has three distinct components, each addressing a different financial exposure.
• Built-in allowances for code-related costs may be small and may not reflect full reconstruction expenses.

Together, these points show why ordinance or law coverage often deserves a closer look during policy renewal.

How to approach coverage decisions

Three practical inputs typically influence how owners size and review their ordinance or law limits:

• Building age, what codes the local jurisdiction has adopted, and current construction costs can all affect how large the coverage gap may be.
• Engineering assessments can show where a building stands today compared to what current codes require.
• Lenders may require minimum coverage levels tied to insurable value.

These factors influence whether coverage limits keep pace with reconstruction costs over time. For organizations seeking support with building condition assessments or code compliance evaluations, Contact Us to speak with a qualified expert.

How building code upgrade coverage works

Building code upgrade coverage is aninsurance endorsement that may pay the extra cost of rebuilding to meet current codes after a covered loss. The National Association of Insurance Commissioners (NAIC) describes it as coverage for the additional cost to rebuild to meet new or updated codes that did not exist when the building was first built.

The endorsement exists because standard commercial property policies focus on replacing what was there, not on bringing older systems up to today’s requirements. The size of that compliance gap depends partly on what protection a standard form already includes.

The built-in provision is often not enough

The small allowance built into some standard property forms tends to fall short on older buildings or major losses. That allowance applies only on policies written to pay full rebuild cost, and it may run out quickly once code-related costs start adding up. Ordinance or law coverage exists to fill the rest of the gap through three separate categories.

The three coverage components

Building code compliance costs do not come from a single bucket. They are split into three separate parts, each with its own coverage limit, because each addresses a different exposure that standard property forms leave out. Lettered A through C, the components each play a specific role in covering the financial impact of compliance work.

Coverage A: Loss to the undamaged portion

Coverage A, also called Loss to the Undamaged Portion, addresses the loss in value of a building’s undamaged portion when a local ordinance requires full demolition. This applies in jurisdictions that require total teardown once damage exceeds a set percentage of building value. The protection typically falls within the existing building property limit, so it does not need its own dollar amount in the policy. Because that limit calculation depends on accurate pre-loss value, a documented building condition assessment before a loss can help establish the figure.

Coverage B: Demolition costs

Coverage B, also called Demolition Cost Coverage, may pay the cost of demolishing the undamaged portion and clearing the site when an ordinance requires full demolition. A standard policy typically covers only debris removal from the original damaged area, so anything beyond that scope may fall to Coverage B. Unlike Coverage A, Coverage B requires its own scheduled dollar amount, which the property owner picks when the policy is written.

Coverage C: Increased cost of construction

Coverage C, also called Increased Cost of Construction, is often the largest financial exposure of the three. It may pay the extra cost of bringing both damaged and undamaged portions up to current code during reconstruction. That can include fire sprinkler retrofits, ADA-compliant elevators or ramps, modern electrical wiring, seismic or hurricane bracing, energy-efficient mechanical systems, and other compliance work that goes beyond restoring what was there before.

Potential financial risks of inadequate coverage

When the limits on those three components fall short, property owners may face large gaps between what insurance pays and what reconstruction costs. Fannie Mae’s Multifamily Lending Guide requires ordinance or law coverage for all non-conforming multifamily properties, and other lender programs may require minimum coverage levels tied to insurable value. The U.S. Department of Housing and Urban Development (HUD) similarly requires this coverage on properties that no longer meet current building, zoning, or land use rules.

As a simplified illustration: on a $5 million commercial property, an owner might select Coverage B and Coverage C limits of $1.25 million each, providing up to $1.25 million for demolition and another $1.25 million for code-driven reconstruction. Carriers may set these limits as scheduled dollar amounts or as percentages of building value, and actual amounts vary by carrier, building type, and risk profile.

Beyond the cost gap, compliance work can also stretch the reconstruction timeline. New permits, added scope, and updated systems may push restoration well beyond the time needed for the original damage repair. Both the financial gap and the timeline impact often hinge on what can be documented, and detailed damage inspections after a loss can help separate compliance costs from direct damage costs.

Building codes that may trigger upgrade costs

Most of those compliance costs typically come from a handful of specific code frameworks that affect older commercial buildings during reconstruction. The wider the gap between the original construction edition and the current edition, the more extensive the required upgrades may become.

Most of those frameworks come from the International Code Council (ICC), which publishes I-Codes on a three-year cycle that most U.S. jurisdictions adopt in some form. Among the codes most likely to add cost during reconstruction, several stand out:

• The International Existing Building Code can affect the scope of required upgrades across multiple building systems.
• Americans with Disabilities Act requirements may call for accessible routes and restrooms.
• Fire protection codes from the National Fire Protection Association (NFPA) may require sprinkler installation in buildings that previously had none.
• Energy codes including the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) Standard 90.1 can trigger upgrades to insulation, lighting, and heating, ventilation, and air conditioning systems.

Together, these frameworks may affect how much compliance work a reconstruction project may involve. Fire code consulting can help property owners understand which specific editions apply.

Whether each of these codes applies depends on what the local jurisdiction has adopted. The Federal Emergency Management Agency Building Code Adoption Tracker monitors approximately 22,000 jurisdictions across the country. About 32% of hazard-prone jurisdictions have adopted current hazard-resistant codes, according to the Federal Emergency Management Agency tracker. This suggests much of the commercial building stock in high-risk areas still operates under older editions, which can widen the upgrade exposure after a loss.

Common challenges with ordinance or law coverage

On top of those code dynamics, setting and maintaining appropriate ordinance or law protection comes with a few recurring challenges. Owners commonly face limited technical data when sizing limits, heavy documentation requirements when filing claims, construction cost changes between renewals, and disputes over policy language. Each tends to surface at a different point in the policy life cycle, from underwriting through claim resolution.

Sizing coverage limits is rarely straightforward

Sizing Coverages B and C typically requires technical data that owners may not have on hand. Appropriate limits typically depend on building age, local code adoption status, and current construction costs. A condition assessment that compares a property against current code requirements can give owners and underwriters a clearer basis for those limits.

Claims documentation can be heavy

An ordinance or law claim usually requires more paperwork than a standard property damage claim. Claimants may need to point to the specific code provision being triggered, show the cost difference between pre-loss and code-compliant reconstruction, and confirm the upgrade is required as a condition of the building permit. Tying each provision to a specific cost is often the most demanding part of the documentation.

Construction cost changes can leave limits behind

Limits set when the policy was first written may not match what reconstruction costs today. As material and labor prices shift between renewals, coverage that was once adequate can fall behind. To keep up with those shifts, periodic limit reviews tied to current construction cost data help reduce the lag.

Policy language can create disputes

Ordinance or law claims often run into gray areas in the policy: what counts as the “undamaged portion,” what damage level triggers a code requirement, and whether a particular upgrade is mandatory or only recommended. When those questions come up, up-to-date property records of pre-loss conditions and code compliance status can give all parties a clearer baseline.

Why building code upgrade coverage may warrant ongoing review

Ordinance or law coverage closes a gap that standard commercial property insurance leaves open: the cost of meeting today’s codes during reconstruction. Its three components address loss to the undamaged portion, demolition costs, and increased construction costs, exposures that standard rebuild-cost coverage alone does not reach. Building age, local adoption cycles, and shifting construction costs can all affect whether limits stay aligned with reconstruction exposure over time.

To stay ahead of those changes, technical assessments from qualified professionals can give property owners the data needed to set more accurate limits before a loss reveals the gap.

Frequently Asked Questions

What percentage of building damage typically triggers the requirement to bring the entire structure up to current building codes?

Thresholds vary widely by jurisdiction. Many follow the substantial improvement threshold (a damage-to-value percentage) used in the International Existing Building Code and federal floodplain regulations, while others apply locally adopted damage percentages.

What are the three components of building code upgrade coverage?

Building code upgrade coverage, also called ordinance or law coverage, has three components. Coverage A, Loss to the Undamaged Portion, addresses the loss in value of the part of the building that was not directly damaged when a local ordinance requires full demolition. Coverage B, Demolition Cost Coverage, may pay the cost of demolishing the undamaged portion and clearing the site. Coverage C, Increased Cost of Construction, may pay the extra cost of bringing both damaged and undamaged portions up to current code during reconstruction. Coverage B and Coverage C each require their own scheduled dollar amount in the policy.

What does the process of filing a claim for ordinance or law coverage typically involve?

Filing typically requires identifying which code provisions were triggered and quantifying the additional reconstruction cost. Supporting documents typically include building permits, contractor estimates, and code official correspondence.
