Building Code & Ordinance or Law Coverage

Ordinance or Law coverage is one of the most valuable and most misunderstood coverages in a homeowners insurance policy. Many people call it "code upgrade coverage," and while that is partly accurate, the name sells it short. This coverage is broader than just building codes. It covers any legally required changes to your property after a loss — including building codes, zoning requirements, historical district appearance standards, and any other city or county regulations that affect how your home must be rebuilt or repaired.

Why "Code Upgrade Coverage" Is Too Narrow a Name

When people hear "Ordinance or Law," they immediately think of building codes — requirements for wiring, plumbing, insulation, structural standards, and similar construction specifications. Building codes are a major part of this coverage, but they are not the only part. The coverage applies to any ordinance or law that regulates the construction, repair, or demolition of a building. That includes:

• Building codes: Updated electrical, plumbing, structural, energy efficiency, and fire safety requirements adopted since your home was originally built
• Zoning requirements: Changes in setback requirements, lot coverage limits, height restrictions, or land use designations that affect how or whether your home can be rebuilt in its current configuration
• Historical district requirements: If your home is in a designated historical area, you may be required to use specific materials, maintain certain architectural features, or follow appearance standards that go well beyond typical building codes
• Any other city or county regulations: Flood zone requirements, seismic retrofit mandates, accessibility standards, and other local regulations that apply to reconstruction or major repair

The Three Coverage Parts

Ordinance or Law coverage is typically divided into three distinct parts, each addressing a different financial impact of having to comply with current laws during reconstruction:

Coverage A — Loss in Value of the Undamaged Portion

When a law or ordinance requires demolition of the undamaged portion of your home, Coverage A compensates you for the value of that undamaged structure. For example, if a fire damages 60 percent of your home but the local building code requires that any structure with more than 50 percent damage be completely demolished and rebuilt, you lose the remaining 40 percent of undamaged structure not because of the fire, but because of the law. Coverage A pays for that additional loss.

Coverage B — Demolition Cost

When you are legally required to tear down the undamaged portion, someone has to pay for that demolition. Coverage B covers the actual cost of demolishing the undamaged structure that would not have been demolished if the law did not require it.

Coverage C — Increased Cost of Construction

This is the part most people think of when they hear "code upgrade." Coverage C pays for the increased cost of rebuilding to comply with current codes and standards. If your home was built in 1970 and must now be rebuilt to 2025 standards, the additional cost of modern wiring, plumbing, insulation, fire-resistant materials, energy-efficient windows, and seismic reinforcement is covered under Coverage C. This is also where historical district appearance requirements and other non-code regulations are addressed — the increased cost of using period-appropriate materials, matching architectural details, or meeting any other legal standard that applies to the rebuild.

Different Cities, Different Codes, Different Timelines

An important detail that many homeowners overlook is that different cities and counties adopt building codes at different times. California has a statewide building code that is updated on a regular cycle, but individual municipalities may adopt local amendments or enforce different versions at different times. The code requirements in Los Angeles may differ from those in Sacramento, and both may differ from unincorporated county areas. This means the increased cost of construction varies significantly based on where your home is located and when the local jurisdiction last updated its adopted code.

Historical Districts: More Than Building Codes

If your property is located in a designated historical district, the requirements for reconstruction or major repair may go far beyond standard building codes. Historical districts often impose appearance requirements — specific materials, architectural styles, window types, roofing materials, and exterior finishes. These are not technically "building codes" in the traditional sense, but they are ordinances and laws that regulate how your building must be constructed. Ordinance or Law coverage applies to these requirements as well, which is why calling it simply "code upgrade coverage" misses a significant part of its value.

Do You Have This Coverage?

Many homeowners do not know whether their policy includes Ordinance or Law coverage, and if it does, what the limits are. Some policies include a basic amount built in, while others offer it as an endorsement with selectable limits. Check your declarations page for an Ordinance or Law line item, and review your endorsement list carefully. If you do not see it, contact your agent and ask specifically.

If you have recently suffered a loss and are navigating this coverage for the first time, a licensed Public Adjuster can help you identify and maximize every dollar available under your Ordinance or Law coverage. This is complex coverage, and it is frequently underutilized because neither the homeowner nor the insurer’s adjuster fully understands the local requirements that apply to the property.
