A commercial property policy pays to repair or rebuild what was damaged — but it doesn't automatically pay to bring the rest of the building up to current building code. That gap shows up after a partial loss on an older building, when a city inspector requires the whole structure to meet today's code before a certificate of occupancy is issued, and the policy simply wasn't built to cover it. Ordinance or law coverage closes that gap. It's one of the most commonly underinsured pieces of a commercial property program, largely because it doesn't matter at all until a specific, fairly common scenario happens — an older building, a partial loss, and a local building code that's moved on since the building was constructed.
