Ordinance or Law Coverage (CP 04 05) 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 costs the standard policy excludes: the lost value of an undamaged part of the building you are required to demolish, the cost of that demolition, and the extra cost of rebuilding to current code.

The most expensive misunderstanding is this: a standard policy pays to rebuild what the fire destroyed, but not a dollar more to meet codes that changed after the building went up. A building that is 40% burned can become a total loss once the building department gets involved, because a demolition ordinance can require the whole building to come down once damage passes a threshold. Without this endorsement, the owner pays that difference.

What Is Ordinance or Law Coverage?

Ordinance or law coverage, also called ordinance and law or building ordinance coverage, is an endorsement to a commercial property policy that pays code-enforcement costs caused by a covered loss, such as the building department requiring demolition and upgrades after a fire. It pays only for what the ordinance requires. Upgrades you choose to make beyond what the law requires are not covered.

What Does the Base Commercial Property Policy Exclude?

The base policy excludes code-enforcement losses. The Causes of Loss Special Form has an Ordinance or Law exclusion that bars loss from enforcing any ordinance that regulates the construction, use or repair of a property or requires a building to be demolished. It applies bluntly. If a fire damages 55% of your building and the city orders the whole building demolished, the unendorsed policy pays only for the fire-damaged part. The adjuster works from the building official's substantial-damage letter, so make sure a copy is in the claim file.

Demolition triggers vary by jurisdiction. Communities in floodplains that enforce FEMA's substantial damage standard must require full compliance with current codes once repair costs reach 50% of the structure's pre-damage market value, counting damage from any cause.^[1] So a fire in a flood zone can trigger elevation requirements even though flooding had nothing to do with it, a determination FEMA's Substantial Improvement/Substantial Damage Desk Reference walks building officials through.^[2]

The base CP 00 10 includes only a token amount. Its Increased Cost of Construction coverage applies only under the replacement cost option and is capped at the lesser of $10,000 or 5% of the building limit, which is small for most buildings. CP 04 05 exists to close that gap.

What Are the Three Coverages in CP 04 05?

CP 04 05 has three separate coverages, and each applies only if it is selected on the endorsement schedule. They work together in a single loss but are priced, limited and triggered differently:

Coverage A (undamaged portion) adds no extra dollars of protection. It sits inside your building limit, and ISO rules require coinsurance of 80% or more. If you rebuild under the replacement cost option, the insurer pays what you spend, up to your limit. If you don't rebuild, recovery drops to actual cash value.

Coverage C has 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 sounds generous until you rebuild after a regional disaster, when permit backlogs and contractor shortages use up most of it. The insurer can extend the deadline, but only in writing and only within the two years, so ask well before it runs out.

One more rule affects owners with mixed losses. When covered and uncovered damage together trigger an ordinance, the insurer pays only the share caused by covered damage. In areas exposed to flood or earthquake, pair this endorsement with flood and earthquake coverage.

How Much Should You Buy, and What About Tenants?

Buy Coverage B and C limits from real contractor estimates, because Coverage A needs no separate limit. For Coverage B, get a demolition contractor's price to take down and clear a building of your size and type, keeping in mind that clearing after a partial demolition is slower than a clean teardown. For Coverage C, the key factor is how old the building is compared with the current code cycle: being one cycle behind can mean sprinkler, seismic, energy and accessibility upgrades all at once. Price both from a contractor estimate, not a rule-of-thumb percentage.

Tenants face the same exposure on a smaller scale. Improvements a tenant builds are the tenant's insurable interest, but CP 04 05 attaches to the owner's policy 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 it.

How to check your ordinance or law coverage

Pull your property policy's schedule, confirm that Coverages A, B and C of CP 04 05 are all selected, and set the B and C limits from a real contractor estimate. The endorsement buys back three code-enforcement costs the property policy excludes: the lost value of an undamaged part you must demolish, the demolition itself, and rebuilding to current code. The built-in version tops out at $10,000 or 5% of the building limit, which disappears quickly on a real building.
