Your house burns down. The fire department clears the scene, your adjuster walks the lot, and you’re ready to rebuild. Then the city steps in. Your home was built in 1978, and current building codes require upgraded electrical panels, additional fire blocking in the walls, and a sprinkler system the original structure never had. The cost to bring the new build up to code adds $40,000 to your reconstruction bill. Your standard homeowner’s policy covers what was there before. Not what the law now requires. That $40,000 is yours to absorb, unless you have ordinance or law coverage.
This is one of the most consequential gaps in residential insurance. Most homeowners have no idea it exists until they’re staring at a contractor’s estimate that doesn’t match their settlement check.
What Ordinance or Law Coverage Actually Does
| Coverage Component | What It Covers | Triggers |
|---|---|---|
| Coverage A: Undamaged Portion Loss | Loss of value from structures forced to demolish due to >50% damage rule | Demolition ordinances in jurisdiction |
| Coverage B: Demolition Costs | Actual cost to tear down undamaged portions | Same as Coverage A |
| Coverage C: Increased Cost of Construction | Difference between old-code and current-code rebuild costs (wiring, HVAC, energy efficiency, ADA features, foundation work) | Current building code requirements at time of loss |
Standard homeowner’s policies are built around one idea: restore the property to its pre-loss condition. That sounds fair until you realize “pre-loss condition” means pre-loss code compliance too. If your home was legally built in 1965, your insurer’s obligation is to rebuild a 1965-code house. The fact that your municipality won’t permit that anymore is, in the standard policy’s view, not their problem.
Ordinance or law coverage fills that gap. It pays for the additional costs required to bring a damaged or destroyed structure into compliance with current building codes, zoning laws, and municipal ordinances. Most policies that include it break it into three components, and knowing what each does is critical.
Coverage A: Undamaged portion loss. Many jurisdictions have “demolition ordinances” requiring that if more than 50% of a structure’s value is damaged, the entire building must be torn down and rebuilt to current code, not just the damaged section. This component covers the loss of the undamaged portion you’re forced to demolish.
Coverage B: Demolition costs. This covers the actual cost of tearing down that undamaged portion. Separate from Coverage A because the loss of the structure and the cost of removing it are two different line items.
Coverage C: Increased cost of construction. This is the big one. It pays the difference between what it costs to rebuild to old standards versus current code requirements. Upgraded wiring, modern HVAC systems, energy efficiency mandates, ADA-compliant features if applicable, foundation reinforcements. All of it.
Some insurers bundle these components; others let you select limits independently. Ask your agent specifically which components your policy includes.
Who Actually Needs This (Hint: Most Homeowners)

Anyone whose home is more than 15 years old. But that’s only the easy answer.
Building codes get updated constantly. The International Building Code sees major revisions every three years. Local jurisdictions adopt those changes on their own schedules, which means a home built in 2005 could already be two or three code cycles behind. I’ve seen claims on homes less than 20 years old where code upgrades added 20% to reconstruction costs.
Older homes carry even more exposure. Knob-and-tube wiring, cast-iron plumbing, single-pane windows, inadequate insulation, missing anchor bolts on foundations, no arc-fault circuit interrupters. Each of those deficiencies is a potential code upgrade trigger when you file a major claim.
The risk compounds in areas with active building code enforcement, coastal zones with wind-load requirements, wildfire-prone regions adopting ember-resistant construction standards (the IBHS home fortification guides detail exactly what these newer standards require), and cities with aggressive historic preservation or energy efficiency mandates.
If your home is old, in a high-risk zone, or in a municipality known for strict enforcement, ordinance or law coverage isn’t optional. It’s a baseline.
The Limits Problem: Why “Some Coverage” Isn’t Enough
Many policies include a small amount of ordinance or law coverage by default, often 10% of your dwelling coverage limit. On a $400,000 dwelling policy, that’s $40,000. Sounds reasonable until you price out a full foundation upgrade, new electrical service, and modern fire suppression in a major metro area.
The coverage amount needs to be calibrated to your actual exposure, not a round percentage.
Your home’s age and construction type matter most. A 1940s craftsman with original systems carries far more code-upgrade risk than a 2008 colonial. Your local jurisdiction’s enforcement history matters too. Some municipalities are aggressive about requiring full code compliance on rebuilds; others focus only on the damaged systems. Your state’s insurance department can sometimes point you toward resources on local ordinance enforcement patterns, though the most reliable source is a licensed local contractor who’s navigated recent rebuilds in your area.
A reasonable starting point for older homes in active-code jurisdictions: 25% to 50% of your dwelling limit. For a $400,000 policy, that’s $100,000 to $200,000 in ordinance or law coverage. It typically adds very little to your annual premium, which makes underinsuring here a poor trade.
How to Evaluate Your Current Policy
Pull out your declarations page. Look for “ordinance or law,” “building ordinance,” or sometimes “increased cost of construction.” If you don’t see it, it may not be there.
Step 1: Identify which components are included. Coverage A, B, and C, as described above. Some policies only include C. That’s a problem if your jurisdiction has a 50% demolition rule.
Step 2: Check the sublimit. Ordinance or law coverage almost always carries its own sublimit separate from your dwelling limit. Know what it is and compare it to realistic rebuild costs in your area.
Step 3: Ask about endorsements. If your current limit is 10% and you want 25%, ask your agent about increasing it. This is usually a straightforward endorsement, not a new policy.
Step 4: Get a local rebuild estimate. Talk to a licensed general contractor in your area about what current code compliance typically adds to a full rebuild on a home like yours. Use that number to sanity-check your sublimit.
Step 5: Document what you have. A home inventory, stored somewhere fireproof and accessible, supports every part of a claim. A document safe rated for fire and water gives you a physical backup. Digital apps like Encircle or home inventory tools on your phone work too. (This site may earn a commission on qualifying Amazon purchases.)
What Ordinance or Law Coverage Does Not Cover
This coverage applies when a covered peril, fire, windstorm, hail, and others listed in your policy, triggers a claim that then exposes code-upgrade requirements. It does not apply when:
You’re doing voluntary renovations. If you decide to remodel your kitchen, you’re responsible for bringing that work up to code at your own expense. No claim, no coverage.
The damage is from an excluded peril. If flooding damages your home and flood isn’t covered under your homeowner’s policy, ordinance or law coverage from that policy won’t pay for code upgrades related to the flood damage either. Your flood policy would need its own provisions.
You’re in a municipality that hasn’t adopted updated codes. Less common, but in some rural jurisdictions, “current code” looks a lot like 1985. Less exposure, less need.
Pre-existing violations. If your home already had unpermitted work or existing code violations before the loss, your insurer may dispute coverage for bringing those specific items into compliance. Document your home’s permitted condition carefully.
The gap between what standard insurance covers and what modern building codes require is real, growing, and expensive. Codes tighten after every major disaster cycle. Homes age. The math only goes one direction. Spend 20 minutes with your policy documents and one conversation with a knowledgeable local agent now. It’s far better than negotiating with an adjuster over a $40,000 shortfall after your worst day as a homeowner.
