Ordinance or Law Coverage Carolina Homes vs Coverage A

Opening answer

Ordinance or law coverage, often called code-upgrade coverage, can help pay the extra cost of rebuilding a South Carolina or North Carolina coastal home to current building codes after a covered loss, instead of restoring the house only to the way it stood before the damage. A typical homeowners policy is written to repair or replace the dwelling as it existed, and that policy generally will not pay the added expense of meeting newer codes. [1][2] The gap sits beside dwelling Coverage A, beside a separate flood policy, and beside any named-storm deductible.

What ordinance or law coverage actually pays

Building codes change. A house permitted in Myrtle Beach, Charleston, Wilmington, or along the Outer Banks decades ago followed the rules in force at that time. After a fire, wind, or similar covered loss, local officials can require the repair or rebuild to follow the codes that apply now. The Insurance Information Institute notes that even a guaranteed replacement-cost policy generally will not pay that extra expense, and that an Ordinance or Law endorsement can pay a specified amount toward bringing the house up to code during a covered repair. [1]

The same point appears in III guidance on a standard HO-3 form, the policy type the South Carolina Department of Insurance describes as the most widely used homeowners contract. [2][3] In one III example, a house close to the ocean would have to be rebuilt on stilts under a town’s new code, adding $30,000 to the rebuild. The HO-3 excludes costs caused by ordinances or laws that regulate construction unless the household buys an Ordinance or Law endorsement. [2]

International Risk Management Institute defines ordinance or law coverage as protection for loss caused by enforcement of ordinances or laws that regulate construction and repair of damaged buildings. Older structures may need upgraded electrical, HVAC, and plumbing. Many communities also require that a building damaged to a specified extent, typically 50 percent, be demolished and rebuilt to current codes rather than simply repaired. IRMI groups that exposure into three cost buckets: the loss of the undamaged portion of the building when demolition is required, the cost of demolishing that undamaged portion, and the increased cost of rebuilding to current codes. Standard homeowners policies include a limited amount of building ordinance coverage, and that amount can be increased by endorsement. [4] After a disaster, III notes that this coverage is addressed under ordinance or law in the Section I exclusion part of the policy. [5]

Coastal Carolina work can include elevation to current flood design, stronger roof connections, updated electrical service, and mechanical equipment moved above required flood elevations. None of that is a free upgrade. It is a legal condition of the permit. Ordinance or law coverage is the policy part that can respond when the underlying loss is a covered homeowners peril.

How Carolina codes create extra rebuild costs

South Carolina’s Building Codes Council adopted the 2021 South Carolina Building Codes on October 6, 2021, with an effective date of January 1, 2023. [6] Local officials in Horry, Georgetown, Charleston, Beaufort, and inland counties enforce that statewide residential code on new work and on repairs treated as substantial. The City of Charleston enforces Coastal A Zone flood design for new construction and substantial improvements under 2021 South Carolina Building Code section 1612 and 2021 South Carolina Residential Code section R322, which became effective statewide on January 1, 2023. [7]

Charleston also applies the National Flood Insurance Program 50 percent rule. If the cost of reconstructing, rehabilitating, adding to, or improving a structure equals or exceeds 50 percent of the building’s assessed or appraised value, the building must meet the same construction requirements as a new building. Structures damaged, from any cause, by 50 percent or more of the building’s value must be brought into compliance with current floodplain requirements. [7] Anderson County, South Carolina, publishes the same NFIP test for pre-FIRM buildings with lowest floors below the base flood elevation: elevation is required if repair costs are 50 percent or more of the building’s value, calculated for full repair to the before-damage condition even if the owner elects to do less. [8]

A second South Carolina trigger sits in coastal management rules. SCDES Regulation 30-1 defines a habitable structure as destroyed beyond repair when more than 66 2/3 percent of the replacement value has been destroyed. [9] That Bureau of Coastal Management threshold can affect whether an oceanfront house may be rebuilt in place. It is not the same as the NFIP 50 percent test, and a household can face both.

North Carolina is on a slower statewide clock. The Office of the State Fire Marshal states that the 2018 North Carolina State Building Code remains in effect while implementation of the 2024 Code has been postponed. The 2018 residential code has been effective since January 1, 2019. [10][11] The adopted 2024 North Carolina Residential Code, which may be used as an alternate method until it becomes effective, includes Chapter 46 coastal and flood plain construction standards. Section R4601.1 applies those requirements to construction in coastal high hazard areas, ocean hazard areas, regulatory flood plain areas, and all areas designated as a 150 mph wind zone. [12] A substantial repair in New Hanover, Brunswick, Carteret, or Dare County can still force foundations, flood-resistant construction, and wind design that the original house never had.

The Insurance Institute for Business and Home Safety’s 2024 Rating the States study ranked South Carolina third among 18 hurricane-coast states for building-code adoption and enforcement, and ranked North Carolina eighth. [13] Current codes in both states are stricter than the codes that governed many older coastal dwellings. The extra cost of meeting them is what ordinance or law coverage is designed to address.

Coverage A is not a code-upgrade fund

Dwelling Coverage A is the limit that pays to repair or rebuild the house and attached structures after a covered loss. The North Carolina Department of Insurance describes Coverage A as the amount it would take to rebuild the home and advises households to carry at least 80 percent of full replacement cost, without counting the land. Replacement cost, in that guidance, is the amount it would take to replace or rebuild with materials of similar kind and quality, without deducting for depreciation. [14]

The National Association of Insurance Commissioners makes the same rebuild-cost point: dwelling coverage should be enough to cover the cost to fully rebuild the insured home, and the policyholder must pay the deductible before the insurer pays. [15] Similar-kind-and-quality is the key phrase. Coverage A restores what was there. It does not automatically buy a higher wind rating, a new elevation, or electrical service that the original house never had. That is why ordinance or law coverage is written as a separate limit, often as a percentage of Coverage A. [1][5] Raising Coverage A to match local rebuild costs is important work. That increase still may not fund code-driven extras unless the ordinance or law limit was reviewed at the same time. NCDOI notes that Coverage B for detached buildings on the residence premises is normally 10 percent of Coverage A; the ordinance or law provision, not Coverage B alone, is the part of the contract that can respond to a code-driven rebuild of a garage or shed. [14]

Flood policies handle a different kind of code bill

Flood is not a covered peril on a standard homeowners policy. The National Flood Insurance Program states that most homeowners insurance does not cover flood damage, and that flood coverage is a separate policy that can apply to buildings, contents, or both. [16] The South Carolina Department of Insurance repeats that rule: the standard homeowner’s policy does not include coverage for flood damage, including damage from storm surge, and a separate flood policy is needed. [17] SCDOI also notes that HO-3 contracts usually exclude floods and earthquakes. [3]

Because ordinance or law on a homeowners policy follows the homeowners perils, it does not convert a wind policy into a flood policy. Code upgrades required after a flood are a flood-program issue. The Association of State Floodplain Managers reports that Increased Cost of Compliance (ICC) coverage on an NFIP policy provides up to $30,000 to bring flood-damaged buildings into compliance with local ordinances, through elevation, demolition, or relocation when the community declares the building substantially damaged or repetitively damaged. [18] That $30,000 figure, current in ASFPM’s November 2025 fact sheet, is a floodplain-ordinance benefit. It is not a substitute for homeowners ordinance or law coverage after a wind or fire loss.

A house in a Special Flood Hazard Area in Charleston, Myrtle Beach, or Nags Head can need floodplain elevation after a flood, which is an ICC question, and can need wind or electrical upgrades after a covered homeowners loss, which is an ordinance or law question. A flood policy does not fill a homeowners code gap, and a homeowners endorsement does not pay NFIP flood losses. Households comparing the two contracts can review the agency’s flood coverage page alongside the homeowners policy.

Named-storm deductibles are a cost share, not an upgrade fund

Named-storm and hurricane deductibles are a third, separate line on many Carolina coastal policies. They do not buy code upgrades. They change how much of a covered wind loss the household pays before Coverage A begins.

NAIC’s June 2024 consumer insight explains that a named-storm deductible applies only when a named storm causes the damage, that it is separate from the normal homeowners deductible, and that it is usually a percentage of the home’s value, commonly in a 1 percent to 10 percent range. NAIC lists both South Carolina and North Carolina among the states that currently have some form of hurricane or named-storm deductible. [19]

South Carolina regulation 69-56 defines a named-storm deductible as a separate deductible triggered by a weather-related event named by the U.S. National Weather Service or the National Hurricane Center, limited to a hurricane, tropical storm, or tropical depression. Insurers that use a hurricane, named-storm, or wind/hail deductible must illustrate how it functions on a $100,000 policy and must explain the event that will trigger it. [20] III reports that South Carolina insurers must notify residential policyholders if the policy contains that separate deductible, with an example and a clear explanation of the trigger. North Carolina households can see similar percentage deductibles on voluntary-market policies and on residual-market placements through the North Carolina Joint Underwriting Association and the Coastal Property Insurance Pool. [21]

The three pieces do different jobs. The named-storm deductible is the household’s share of a covered storm loss. Coverage A is the rebuild fund for the house as it was. Ordinance or law is the extra fund for code-required work that the original house did not include. Paying a large storm deductible does not increase the ordinance or law limit.

How to review the gap on a Carolina policy

A useful review is a document check, not a forecast of the next storm. Start with the declarations page and the ordinance or law wording in Section I. Confirm whether the policy includes a limited built-in amount, as IRMI describes for many homeowners forms, or whether an endorsement was added, as III describes for HO-3. [4][2] Note the limit as a percentage of Coverage A or as a dollar cap. A small built-in amount can be enough for a recently built house that already meets 2021 South Carolina codes. It can be thin for a pre-FIRM house in a Charleston or Horry floodplain, or for an older Outer Banks dwelling that would have to meet current coastal construction standards after a substantial repair. [7][12]

Match the house to the code a building official would apply. In South Carolina, that is the 2021 statewide family of codes, plus any local floodplain ordinance such as Charleston’s 50 percent rule and freeboard. [6][7] In North Carolina, that is the 2018 code still in force, with Chapter 46 rules applying in mapped high-hazard, ocean-hazard, floodplain, and 150 mph wind areas. [10][12] Year of construction, lowest-floor elevation, and flood-zone status all change the size of the possible code delta. If the lot is in a mapped flood hazard area, ICC on the flood policy and ordinance or law on the homeowners policy are two different answers to two different permits. [16][18]

Read the storm deductible so it is not mistaken for extra coverage. A 2 percent or 5 percent named-storm deductible on a $400,000 Coverage A limit is $8,000 or $20,000 of the household’s money on a qualifying storm claim. [19] That amount comes out before Coverage A pays. It does not fund elevation or electrical upgrades required by current code. Independent agents who already shop homeowners coverage across multiple carriers for South Carolina and North Carolina households can line those three items up on the same page: Coverage A adequacy, ordinance or law limit, and the storm deductible, with flood treated as its own contract.

Practical takeaways

• Ordinance or law coverage pays extra costs of meeting current building codes after a covered homeowners loss. It is not a bonus on top of market value, and it is not automatic just because Coverage A looks large. [1][2]
• South Carolina’s 2021 codes have been in force since January 1, 2023. North Carolina’s 2018 codes remain in force while the 2024 codes wait on a delayed effective date. Older coastal houses in both states can face a real code gap on a substantial repair. [6][10]
• The NFIP 50 percent substantial-damage and substantial-improvement test, used in Charleston, Anderson County, and participating communities across both Carolinas, can force a rebuild to current floodplain standards. That trigger is separate from Coverage A. [7][8]
• A flood policy’s Increased Cost of Compliance benefit, reported at up to $30,000 in 2025 ASFPM guidance, applies to floodplain ordinances after severe flood damage. It does not replace homeowners ordinance or law coverage after wind or fire. [18]
• Named-storm deductibles in South Carolina and North Carolina are a percentage cost share on a qualifying storm. They are not a code-upgrade fund. [19][20]
• The declarations page should show the ordinance or law limit, usually as a percentage of Coverage A. If the line is missing or the percentage looks small relative to the age of the house, ask the agent to quote a higher limit before the next renewal.
