Ordinance or law coverage

When a covered loss damages part of your home, the contractor rebuilding it has to comply with current building code — even if the home was built decades ago under older code. The cost gap between "rebuild like-it-was" and "rebuild to current code" is what ordinance-or-law coverage pays. Common upgrades triggered: electrical panel replacement, plumbing upgrades, structural retrofitting for seismic / wind zones, energy-efficiency requirements, ADA-accessibility where applicable. The HO-3 base form typically includes 10% of Coverage A; buy-up endorsements extend to 25% or 50%.

The 10% default sounds adequate until you have an actual older-home claim. A 1970s home with a Federal Pacific electrical panel needs full panel replacement on any covered repair touching electrical — that alone can be $4,000–$8,000. Add code-required ground-fault outlets in every wet location, smoke / CO detector hardwiring, R-value insulation upgrades, and the code-upgrade column can easily exceed $20,000 on a mid-size loss. Without the buy-up endorsement, the homeowner pays the difference out of pocket.

A water loss on an older home destroys 40% of the first-floor drywall. The contractor needs to open walls; once open, current code requires AFCI / GFCI outlets, knob-and-tube replacement of any exposed legacy wiring, and updated plumbing valves at the affected fixtures. Code-upgrade scope: $14,200. Coverage A is $350k; 10% ordinance-and-law = $35k — fits comfortably. The same loss on a 1920s home with full knob-and-tube and lead pipes: code-upgrade scope balloons to $48,000, exceeds the 10% cap, and the homeowner pays $13k out-of-pocket.
