What Is Ordinance or Law Coverage? The CP 04 05 Endorsement Explained

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 you must demolish, the cost of that demolition, and the increased cost of rebuilding to current code.

Here is the misconception that costs owners the most. A standard policy pays to rebuild what the fire destroyed, but not a dollar more to meet codes that changed since the building went up. A 40%-burned structure can become a total loss once the building department gets involved, because a demolition ordinance can force the whole building down past a damage threshold. Without this endorsement, that gap is the owner's.

What Is Ordinance or Law Coverage?

Ordinance or law coverage (also known as ordinance and law coverage or building ordinance coverage) is an endorsement for a commercial property policy which will respond to costs associated with code enforcement caused by a covered loss. These could be items such as the demolition and upgrade of a structure by the local building department due to the damage from a fire. There is one condition. The endorsement only provides for the minimum amount required under the ordinance. Therefore, any voluntary upgrades above what is called for by the law would not be covered.

What Does the Base Commercial Property Policy Exclude?

The Causes of Loss Special Form has an Ordinance Or Law exclusion that bars any losses for enforcement of ordinances which regulate the construction/use/repair of a property, or require the demolition of a building. The exclusion can be very straightforward in its application. For example, if you have a fire damage to 55% of your building and the city issues a full-demolition order as a result of the fire, the unendorsed policy will pay only for the area damaged by the fire. The adjuster works from the building official's substantial-damage letter, so get a copy of it into the claim file.

Demolition triggers vary by jurisdiction. Floodplain communities enforcing FEMA's substantial damage standard must require full compliance with current codes once repair costs reach 50% of a structure's pre-damage market value, counting damage of any origin.^[1] So a fire in a flood zone can trigger elevation requirements it never caused, a determination FEMA's Substantial Improvement/Substantial Damage Desk Reference walks officials through.^[2]

The base CP 00 10 is essentially just an entry level buy-in. Its Increased Cost of Construction is only available through the Replacement Cost option and has a maximum coverage amount that is whichever is less of $10,000 or 5% of the building limit, which is typically very low for most buildings. This is exactly why we have CP 04 05 to help bridge this gap.

What Are the Three Coverages in CP 04 05?

CP 04 05 offers three separate coverages, each selected on the endorsement schedule to apply. They work together at a single loss but are priced, limited, and triggered differently:

The addition of Coverage A (Undamaged Portion) does not add any additional dollars of protection. It is within your building limit, and it is subject to the ISO rule which requires coinsurance of 80% or greater. However if you rebuild on the Replacement Cost Option, then the Insurer will pay as much as you spend up to your limit. And if you don't rebuild, then recovery would drop down to actual cash value.

Coverage C carries the most conditions. It requires the Replacement Cost option, and nothing is paid until the building is actually repaired or replaced within two years. That window sounds generous until you rebuild after a regional catastrophe, when permitting backlogs and contractor shortages eat most of it. The insurer can extend it, but only in writing and only during the two years, so ask well before the deadline.

There is another rule that affects owners who have sustained mixed losses. Where covered and non-covered damage combine to trigger an ordinance, the insurer will only pay for the percentage of covered damage. Therefore, This Endorsement should be used in conjunction with Flood and Earthquake Coverage in Exposed Areas.

How Much Should You Buy, and What About Tenants?

Coverage A needs no sizing, so the work is setting the Coverage B and Coverage C limits. For Coverage B, get a demolition contractor's price to take down and clear a structure of your size and type, since clearing a partial demolition runs slower than a clean teardown. For Coverage C, the driver is the building's age against the current code cycle: one cycle behind can mean sprinkler, seismic, energy, and accessibility upgrades at once. Price both from a contractor estimate, not a rule-of-thumb percentage.

Tenants carry the same exposure on a smaller canvas. Improvements a tenant builds out are the tenant's insurable interest, but CP 04 05 attaches to the owner's and does not reach them. ISO's parallel form, CP 04 26, applies the same A, B, and C structure to those improvements, so tenant accounts should carry both.

The Bottom Line

Ordinance or law coverage, ISO endorsement CP 04 05, buys back three code-enforcement costs your property policy excludes: the lost value of the undamaged portion you must demolish, the demolition, and rebuilding to current code. The built-in version caps near $10,000, which vanishes on any real building. Pull your schedule, confirm Coverages A, B, and C are elected, and set the B and C limits from a real contractor estimate.
