Increased Cost of Compliance (ICC) Coverage Under NFIP

Increased Cost of Compliance (ICC) coverage is a mandatory component of standard National Flood Insurance Program policies that pays toward the cost of bringing a flood-damaged structure into conformance with local floodplain management ordinances. It operates as a supplemental benefit layered on top of building loss payments, subject to its own trigger conditions and dollar cap. Understanding ICC is essential for property owners in regulated floodplains, because the compliance costs it addresses — elevation, demolition, relocation, or floodproofing — routinely exceed what standard repair budgets anticipate.

Definition and Scope

ICC coverage is defined and governed under 44 CFR Part 60, which establishes minimum floodplain management criteria for the National Flood Insurance Program (NFIP). The Federal Emergency Management Agency (FEMA) administers ICC as part of every standard flood insurance policy — it is not an optional rider.

The coverage applies when a structure is determined to be substantially damaged or repetitively damaged by a flood event. Substantial damage is defined under FEMA's floodplain management regulations as damage where the cost of restoring the structure equals or exceeds rates that vary by region of the structure's pre-damage market value (FEMA Floodplain Management Requirements, FEMA P-748). Repetitive loss eligibility — a separate trigger — applies to structures that have been flooded twice within a 10-year period and where each flood produced damage exceeding rates that vary by region of market value.

The maximum ICC benefit is amounts that vary by jurisdiction per policy (FEMA, National Flood Insurance Program Adjuster Claims Manual). This cap applies regardless of actual compliance costs, which means it functions as a partial subsidy rather than a full reimbursement mechanism. Policyholders who need to understand where ICC fits among other available coverage options should consult the broader breakdown of flood insurance coverage types.

How It Works

ICC is triggered and paid through a structured process that involves local government, the insurance adjuster, and the policyholder.

1. Flood event and damage assessment. Following a qualifying flood, a licensed flood insurance adjuster evaluates the building. The adjuster's role in this process is described in detail at flood insurance adjuster role.

2. Substantial damage determination. The local floodplain administrator (not the insurance adjuster) issues an official substantial damage determination. This determination — typically delivered as a written letter or municipal notice — is the gatekeeping document for ICC eligibility. Without it, ICC is not payable.

3. Compliance requirement issued. The local government issues an order requiring the property owner to bring the structure into compliance with the community's floodplain management ordinance. Qualifying compliance actions include elevation of the structure to or above base flood elevation, demolition, relocation, or dry floodproofing (for non-residential structures).

4. ICC claim filed. The policyholder files an ICC claim separately from the standard building damage claim. Both claims can run concurrently under the same policy. The combined payment — building loss plus ICC — cannot exceed the building coverage limit on the policy plus the amounts that vary by jurisdiction ICC cap.

5. Payment disbursement. FEMA or the Write Your Own (WYO) carrier releases ICC funds upon documentation that the compliance work has been contracted or completed. The Write Your Own program allows private insurers to issue and administer NFIP policies under FEMA's oversight, so the administering insurer may vary by policyholder.

ICC does not cover the cost of items that would have been covered under the standard building claim — it is strictly limited to the incremental cost of achieving code compliance beyond ordinary repair.

Common Scenarios

Elevation. The most frequent use of ICC funds is raising a structure's lowest floor to meet or exceed base flood elevation requirements. In high-risk Special Flood Hazard Areas (SFHAs), local ordinances frequently require freeboard — elevation above the base flood level — adding further cost. Properties in these zones are discussed in depth at flood insurance for high-risk zones.

Demolition. When the cost to elevate a substantially damaged structure exceeds what is practical, the local ordinance may require demolition. ICC can pay up to the amounts that vary by jurisdiction cap toward demolition costs, with any remainder the owner's responsibility.

Relocation. Structures moved out of the floodplain entirely qualify for ICC assistance to offset relocation costs. This is relatively uncommon but occurs frequently in communities participating in voluntary acquisition programs administered by FEMA's Hazard Mitigation Grant Program.

Dry Floodproofing (Non-Residential Only). Commercial structures that cannot be elevated may be eligible for ICC reimbursement of dry floodproofing measures — waterproof coatings, flood shields, and sump systems — provided the local ordinance accepts floodproofing as a compliance path. Residential structures are generally excluded from this option under NFIP rules.

Comparison — ICC vs. Standard Building Coverage:

Decision Boundaries

When ICC applies: A property must receive both a qualifying flood damage event and a local government substantial or repetitive damage determination. Neither condition alone is sufficient.

When ICC does not apply: Structures that sustain damage below the rates that vary by region threshold — even if the owner voluntarily chooses to elevate — are not eligible for ICC. Voluntary mitigation is handled through other FEMA programs such as the Flood Mitigation Assistance (FMA) grant program, not through ICC. The relationship between mitigation and insurance costs is examined at flood mitigation impact on insurance.

Coverage gap awareness: The amounts that vary by jurisdiction ICC cap frequently falls short of actual compliance costs, particularly for elevation projects in high-cost construction markets. Owners in such situations sometimes layer excess flood insurance or seek supplemental mitigation grant funding to close the gap.

Policy limit interaction: If the combination of building loss payment plus ICC claim exceeds the total building coverage limit, payments are prorated or capped. Policyholders should review flood insurance policy limits alongside ICC to model worst-case outcomes before a flood event, not after.

Community participation requirement: ICC is only available in communities that participate in the NFIP and enforce floodplain management ordinances that meet or exceed FEMA's minimum criteria under 44 CFR Part 60. Communities that have been suspended or placed on probation may affect policyholder ICC eligibility. The NFIP overview provides background on community participation standards.

Basement structures: ICC applies to basement-containing structures, but local ordinances may require specific compliance actions that differ from those for slab-on-grade buildings. Coverage nuances for below-grade spaces are addressed at basement coverage flood insurance.
