Ordinance or law coverage is a commercial property endorsement, ISO form CP 04 05, that pays for losses caused by building code enforcement after covered damage. It buys back three exposures the standard policy excludes: the lost value of an undamaged portion of the building you are forced to demolish, the cost of that demolition, and the increased cost of rebuilding to current code.
A building that is 40% burned can become a total loss the moment the building department gets involved. Many jurisdictions require demolition once damage crosses a threshold, and every rebuild must satisfy the codes in force today, not the codes in force when the building went up. Without this endorsement, that entire gap belongs to the owner.
Ordinance or Law Coverage
What Is Ordinance or Law Coverage?
Ordinance or law coverage, sometimes written as ordinance and law coverage, building ordinance coverage, or ordinance and law insurance, is an endorsement added to a commercial property policy. It responds to losses that are not directly caused by fire, wind, or another covered peril but are a consequence of one. When a covered loss forces you to comply with a building, zoning, or land use ordinance, three costs appear that the base policy will not pay.
The undamaged part of the building may lose its value because the law requires it to come down. Someone has to pay to demolish that undamaged portion and clear the site. And the rebuilt structure must meet the minimum code requirements in force at the time of loss, which almost always costs more than putting back what was there. CP 04 05 addresses all three, each with its own coverage grant and its own limit structure.
One point trips up buyers constantly. The endorsement only pays for the minimum requirements of the ordinance. Voluntary upgrades and recommended standards that exceed what the law actually requires are not covered, no matter how sensible they are.
What Does the Base Commercial Property Policy Exclude?
The Causes of Loss Special Form contains an Ordinance Or Law exclusion in its first group of exclusions, the ones carrying anti-concurrent causation language. It eliminates coverage for loss resulting from enforcement of or compliance with any ordinance or law regulating the construction, use, or repair of property, or requiring property to be torn down.
The practical effect is blunt. If a fire damages 55% of your building and the city requires full demolition, the unendorsed policy pays only for the portion the fire actually damaged. The exclusion also reaches the extra costs of complying with building codes during repair, and it extends to federal laws such as the Americans with Disabilities Act. Many communities mandate demolition once damage reaches a specified percentage of the building, often somewhere between 30% and 60%, and officials frequently hold discretionary authority to order demolition below that threshold when safety is a concern.
The base CP 00 10 does throw owners a small bone. Its Increased Cost Of Construction additional coverage pays code-driven repair costs, but only when the Replacement Cost option applies, and only up to the lesser of $10,000 or 5% of the building limit. On any real building, that sublimit disappears fast. The gap between that token amount and the true exposure is exactly what CP 04 05 exists to fill.
What Are the Three Coverages in CP 04 05?
CP 04 05 offers three separate coverages, and each must be selected on the endorsement schedule to apply. Coverage A pays for the loss in value of the undamaged portion of the building when an ordinance requires its demolition. Coverage B pays the cost to demolish that undamaged portion and clear the site. Coverage C pays the increased cost of construction to bring the repaired or rebuilt structure into compliance with current building, zoning, or land use laws. They work together at a single loss but are priced, limited, and triggered differently.
The following table compares how each coverage is structured:
| Coverage | What it pays | Limit structure | Coinsurance |
|---|---|---|---|
| A: Undamaged portion | Loss in value of the undamaged part the law requires you to demolish | Included within the building limit, does not increase it | Applies, 80% or higher required |
| B: Demolition cost | Cost to demolish undamaged parts and clear the site | Separate scheduled limit | Does not apply |
| C: Increased cost of construction | Extra cost to rebuild damaged and undamaged portions to current code | Separate scheduled limit, or combined with B | Does not apply |
Coverage A sits inside the Limit of Insurance shown for the building, so it adds no new dollars to the policy, and the ISO Commercial Lines Manual rule requires coinsurance of 80% or higher for it. Payment follows the valuation basis on the building. If the replacement cost option applies and you rebuild, the insurer pays what you actually spend up to the building limit. If you do not rebuild, recovery drops to actual cash value.
Coverage C carries the most conditions. The CLM rule requires the Replacement Cost option on the building before Coverage C can be written at all. Nothing is paid until the building is actually repaired or replaced, and the work must be done as soon as reasonably possible, within two years of the loss unless the insurer extends that window in writing.
The restored building must be intended for a similar occupancy, with one useful exception. If zoning has changed so your prior use is no longer permitted, Coverage C pays the increased cost of rebuilding for a different permitted use, and if the ordinance forces relocation, it covers the increased cost at the new premises. When Coverage C applies, excavations, foundations, pilings, and underground pipes come out of Property Not Covered and get protection under this provision.
How Does the Proportional Payment Rule Work?
The endorsement only responds when covered damage is what puts the ordinance in play. If the building sustains only covered direct physical damage, the coverages pay in full up to their limits. If the building sustains both covered and non-covered damage, and it takes the damage in its entirety to trigger the ordinance, the insurer pays only a proportion of the ordinance loss. That proportion is the covered direct physical damage divided by the total direct physical damage.
There is one exception worth memorizing. If the covered damage alone would have triggered the ordinance requirement, the insurer pays the full amount. And if the non-covered damage is itself the subject of the ordinance, there is no ordinance or law payment at all, even when covered damage also occurred.
This rule is the endorsement's own worked example, reproduced in Paragraph F of the form, and it is a strong argument for pairing ordinance or law coverage with flood and earthquake coverage in exposed areas. A large excluded loss shrinks every ordinance payment on the policy.
How Much Ordinance or Law Coverage Should You Buy?
Coverage A takes care of itself once selected, because it lives inside the building limit. The real work is setting the Coverage B and Coverage C limits, which can be written separately or as a single combined limit for both. For Coverage B, price the demolition realistically. Ask a local demolition contractor what it costs to take down and clear a structure of your size and type, because site clearing after a partial demolition is slower and more expensive than a clean teardown.
For Coverage C, the driver is the age of the building relative to the current code cycle. A building even one code cycle behind can face sprinkler retrofit, seismic, energy, and accessibility upgrades all at once. For a building more than 20 years old in a strict code jurisdiction, a Coverage C limit of at least 20% to 25% of the building limit is a defensible starting point, and older unsprinklered buildings justify more.
Two schedule elections deserve attention. The Post-Loss Ordinance Or Law Option extends Coverage C to codes revised after the loss but before reconstruction begins, when compliance is a condition of getting a building permit or certificate of occupancy. Code changes routinely follow major catastrophes, which is precisely when you will be rebuilding. Also note that insureds carrying the Functional Building Valuation endorsement, CP 04 38, already have ordinance or law coverage built in and should reflect the exposure in that form's limit rather than buying CP 04 05 twice.
How Do Tenants Cover Improvements and Betterments?
Tenants carry the same exposure on a smaller canvas. A tenant who builds out a leased space owns an insurable interest in those improvements and betterments, meaning fixtures, alterations, installations, or additions made part of the building at the tenant's expense that the tenant cannot legally remove. If a covered loss triggers a demolition ordinance, the tenant loses the undamaged improvements along with the damaged ones, and rebuilding the space to current code costs more than the original build-out.
CP 04 05 does not solve this, because it attaches to the building owner's interest. ISO publishes a parallel endorsement for the tenant's policy, CP 04 26, Ordinance Or Law Coverage For Tenant's Interest In Improvements And Betterments. It carries the same Coverage A, B, and C structure and the same Post-Loss option, applied to the improvements described in its schedule.
Brokers placing tenant accounts should treat the two forms as a matched set. The schedule on CP 04 26 requires a description of the improvements at each premises, so gather build-out costs at binding rather than reconstructing them after a loss. A tenant relying on the landlord's CP 04 05 is relying on coverage that does not insure the tenant's interest.
Frequently asked questions
Does my commercial property policy automatically include ordinance or law coverage?
No. The Causes of Loss Special Form excludes losses from enforcement of any ordinance or law, and the base policy's built-in Increased Cost Of Construction coverage is capped at the lesser of $10,000 or 5% of the building limit. Meaningful protection requires adding CP 04 05 and selecting each coverage on its schedule.
Is ordinance or law coverage worth it for a newer building?
Usually yes. Demolition ordinances trigger on the percentage of damage, not the age of the building, so even a recent building damaged past the local threshold faces forced demolition of its undamaged portion. Any code adopted since construction, plus post-catastrophe code revisions where the Post-Loss option applies, adds increased cost exposure.
What happens if I choose not to rebuild after a loss?
Coverage C pays nothing, because payment is conditioned on actual repair or replacement within two years unless the insurer extends the deadline in writing. Coverage A still responds, but on an actual cash value basis rather than replacement cost, capped at the building limit.
Does ordinance or law coverage pay for upgrades my city merely recommends?
No. CP 04 05 responds only to the minimum requirements of an ordinance or law in force at the time of loss, or revised post-loss where that option is selected. Costs of complying with recommended actions or standards that exceed actual legal requirements are excluded, as are code obligations you were already required to meet before the loss and ignored.
