Quick answer: Ordinance or law coverage pays the extra cost of rebuilding to current building codes after a covered loss, plus related demolition and debris removal. Many standard homeowners policies based on the ISO HO-3 form include it as an additional coverage equal to 10% of the dwelling limit (Coverage A). Older homes, homes in areas that have adopted stricter codes and homes in flood or hurricane zones can easily exceed that amount, so it is worth asking your insurer about an endorsement that raises the limit. In Florida, insurers must offer ordinance or law coverage of 25% of the dwelling limit, with an option of 50%.
A kitchen fire in a 1970s house rarely gets repaired to 1970s standards. Once a building official reviews the repair permit, the work may have to meet today’s electrical, plumbing, energy, wind and accessibility rules. Those upgrades can add thousands of dollars that a basic dwelling claim does not pay. Ordinance or law coverage exists for exactly that gap.
This article explains how the coverage works, how much is included by default and how to decide whether you need more. For the full map of the policy’s coverages, deductibles and exclusions, see our guide to homeowners insurance coverage.

Why Building Codes Create a Coverage Gap
A standard dwelling claim pays to repair or replace damaged property with materials of like kind and quality. Building codes, however, change over time. Local governments adopt updated codes, often based on the International Residential Code published by the International Code Council, and amend them for local hazards such as wind, wildfire or flooding.
When you repair or rebuild after a loss, the permit you pull usually requires compliance with the codes in force at that time, not the codes in force when your home was built. The difference between “like kind and quality” and “what the code now requires” is the cost that ordinance or law coverage is designed to pay.
Examples of code-driven costs that can surface during a repair include:
- upgrading electrical panels, wiring or adding arc-fault and ground-fault protection;
- replacing plumbing that no longer meets code;
- adding hurricane straps, stronger roof decking attachment or impact-rated openings in wind zones;
- installing hardwired smoke alarms or additional egress windows;
- meeting energy code insulation requirements when walls are opened; and
- elevating a substantially damaged home in a flood zone.
The Three Parts of Ordinance or Law Coverage
Insurance professionals often describe ordinance or law protection in three parts. Personal homeowners forms tend to bundle them together under one limit, while commercial property forms label them separately as Coverage A, B and C.
1. Loss to the undamaged portion of the building
Sometimes a building department requires an entire structure to be demolished because the damaged portion exceeds a threshold. Without this protection, the policy might pay only for the damaged part, leaving you to absorb the value of the undamaged part that was torn down.
2. Demolition cost
Tearing down the undamaged part of a building and hauling it away costs money. This part pays for demolition and removal of debris from the undamaged portion that the law requires you to take down.
3. Increased cost of construction
This is the part most homeowners think of: the extra cost to rebuild or repair to current code compared with rebuilding the original way.
What the Standard HO-3 Form Includes
In the ISO Homeowners 3 Special Form, ordinance or law appears as an additional coverage. In general terms it:
- pays up to 10% of the Coverage A limit for increased costs you incur due to enforcement of an ordinance or law regulating construction, repair or demolition, when the damage results from a covered peril;
- applies to the dwelling and, in the form’s wording, to other structures within limits;
- includes demolition and debris removal of the undamaged part when required by law; and
- is an additional amount of insurance, meaning it sits on top of the Coverage A limit rather than reducing it.
The form also contains limits worth noting. It does not pay for the loss in value of property due to an ordinance, and it does not pay the cost to comply with laws requiring you to test for, clean up or neutralize pollutants. Code upgrades you choose to make that are not required by law are not covered either.
Your insurer may use its own policy language rather than the ISO form, so the percentage and wording on your declarations page and policy jacket are what count. For a refresher on how the dwelling limit is set, read how much dwelling coverage you need.
How the Math Works: A Hypothetical Illustration
The numbers below are hypothetical and only show how the percentage limit is calculated. They are not typical costs.
Suppose a home carries a Coverage A limit of $300,000 and the policy includes ordinance or law at 10%. That makes $30,000 available for required code upgrades and related demolition, in addition to the dwelling limit. If the building department requires $45,000 of upgrades after a covered fire, the policy would pay up to $30,000 for that portion and the owner would carry the remaining $15,000.
With a 25% option, the same home would have $75,000 available. With 50%, it would have $150,000. Your actual figures depend on your own dwelling limit, the endorsement you choose and the policy’s wording on when payment is made. Ask your insurer to walk through the same calculation using your declarations page.
Raising the Limit With an Endorsement
ISO offers an endorsement, Ordinance or Law Increased Amount of Coverage (HO 04 77), and many insurers have their own version. It lets you raise the ordinance or law percentage above the default. Common options include 25% or 50% of Coverage A, though available choices depend on the insurer.
Things to ask about when you consider an increase:
| Question | Why it matters |
|---|---|
| What percentage of Coverage A is included now? | Some policies include 10%, others more, some less |
| Is the limit additional or included in Coverage A? | An additional limit gives more total protection |
| Does it apply to other structures? | Detached garages and sheds may also need code upgrades |
| Is payment on a replacement cost basis? | Many forms pay code upgrades only when the repair is actually made |
| What does a 25% or 50% option cost? | Compare the added premium to your home’s age and local code changes |
Florida's Required Offer
Florida has written ordinance or law requirements into statute. Under Florida Statutes § 627.7011, before issuing a homeowners policy, an insurer must offer ordinance or law coverage. The statute describes coverage of 25% of the dwelling limit, with an option to buy 50%, and allows the policyholder to reject the coverage in writing. Florida homeowners who signed a rejection form at purchase may not have the protection they assume. Check your declarations page and ask your insurer what you have.
Flood Zones, the 50 Percent Rule and ICC Coverage
Homes in a FEMA special flood hazard area face a code issue that can dwarf ordinary upgrades. Under National Flood Insurance Program floodplain management rules, communities must require a building that is “substantially damaged” to be brought into compliance with current floodplain standards. FEMA defines substantial damage as damage where the cost to restore the building equals or exceeds 50 percent of its market value before the damage occurred. Compliance can mean elevating the home, relocating it or demolishing it.
Two coverage points follow:
- Homeowners ordinance or law coverage generally does not apply to flood damage, because flood is excluded from standard homeowners policies to begin with.
- NFIP flood policies include Increased Cost of Compliance (ICC) coverage. FEMA describes ICC as paying up to $30,000 toward elevating, flood-proofing, relocating or demolishing a building that a community determines is substantially damaged by flood.
Our guide to flood insurance basics explains how NFIP and private flood policies differ.
Who Needs More Than the Default
The default 10% can be thin for many homes. Consider a higher limit if any of these apply:
- The home is older. Homes built under much older codes have more ground to make up.
- Your area updates codes often. Coastal, wildfire-prone and seismically active areas tend to adopt stronger construction rules over time.
- Your home has had few major updates. Original wiring, plumbing or roofing raise the odds of code-driven work after a loss.
- You own a historic home. Historic districts may impose design rules in addition to safety codes, which can raise repair costs further.
- You rely on replacement cost coverage. If you plan to rebuild, you will incur code costs, so it makes sense to insure them.
How a Claim With Code Upgrades Works
- Report the loss promptly and document damage with photos and video.
- Get the building department’s requirements in writing. The permit or plan review notes tell your contractor and the adjuster which upgrades are required.
- Ask your contractor to separate costs. An estimate that breaks out “repair to original” and “required code upgrades” makes the ordinance or law portion easier to support.
- Submit documentation for the code portion. Adjusters may ask for the code section or official notice requiring each upgrade.
- Complete the work. Many policies pay code upgrade costs only when the repair or rebuild is actually completed.
Our step-by-step article on how to file a homeowners insurance claim covers documentation and working with the adjuster.
How Ordinance or Law Relates to Other Coverages
| Coverage | What it pays | Relationship to code upgrades |
|---|---|---|
| Coverage A (dwelling) | Repairing the structure with like kind and quality | Does not pay the extra code cost on its own |
| Ordinance or law | Extra cost of compliance, demolition of undamaged portion | Fills the code gap, within its limit |
| Debris removal | Removing debris of covered damaged property | Separate from demolition of undamaged parts |
| Additional living expenses | Extra living costs while the home is unlivable | Code work can lengthen repairs, so this limit matters too |
| NFIP ICC | Up to $30,000 for flood compliance after substantial damage | Applies only through a flood policy |
Questions to Ask Your Insurer
- What percentage of my dwelling limit is available for ordinance or law?
- Is it additional to Coverage A or part of it?
- Does it apply to other structures and to the undamaged portion of the home?
- What options are available to increase it, and what do they cost?
- Do you pay code upgrades only after the work is completed?
- If I am in Florida, did I sign a rejection or a lower selection?
Frequently Asked Questions
What does ordinance or law coverage pay for?
It pays the added cost to repair or rebuild to current building codes after a covered loss, plus demolition and debris removal of undamaged portions when the law requires it, up to the limit in your policy.
Is ordinance or law coverage included in a standard homeowners policy?
Many policies based on the ISO HO-3 form include it as an additional coverage equal to 10% of the dwelling limit. Some insurers include more or less, so check your policy.
How much ordinance or law coverage do I need?
It depends on your home’s age, how much local codes have changed and whether major systems have been updated. Owners of older homes often consider 25% or 50% of Coverage A.
Does ordinance or law coverage apply to flood damage?
Generally no, because flood is excluded from standard homeowners policies. NFIP flood policies include Increased Cost of Compliance coverage of up to $30,000 for substantially damaged buildings.
Can I make upgrades I want and bill them as code work?
No. Ordinance or law coverage pays only for upgrades required by an ordinance or law, not elective improvements.
The Bottom Line
Ordinance or law coverage pays for the difference between rebuilding your home the way it was and rebuilding it the way current codes require. The common default of 10% of Coverage A can fall short for older homes and areas with fast-changing codes. Check your declarations page, ask about increasing the limit by endorsement and, if you are in Florida, confirm whether you accepted or rejected the required offer when you bought the policy.
