Are you unsure if your community participates in the National Flood Insurance Program (NFIP)?
Or confused about whether your property is classified as pre-FIRM or post-FIRM — and why it even matters?
Understanding your community's NFIP status affects insurance rates, options, and compliance with floodplain management rules.
This article covers:
-
What NFIP community status means and how it affects you
-
The difference between pre-FIRM and post-FIRM properties
-
What happens if a community is in the Emergency Program

How to use FEMA tools to look up property classification
Why NFIP Community Status Matters
NFIP community status directly impacts available flood insurance options.
When a community joins the NFIP, FEMA assigns it a Flood Insurance Rate Map (FIRM). The FIRM's effective date determines the building code and insurance rules applied to structures in that area.
Key implications:
-
NFIP participation provides access to federally backed flood insurance.
-
A property’s construction date relative to the FIRM date determines whether it’s pre-FIRM or post-FIRM.
-
This classification affects eligibility for certain insurance products and mitigation strategies.
What Is Pre-FIRM vs. Post-FIRM?
“Pre-FIRM” and “post-FIRM” refer to when a structure was built in relation to a community’s first FEMA-issued FIRM.
-
FIRM effective date: The date the first flood map became active for a community.
-
Post-FIRM: Structures built after this date.
-
Pre-FIRM: Structures built before this date.
Although 1974 is often referenced due to federal program changes, the specific FIRM date for a community is what matters.
Example: If a community’s FIRM date is 1989, structures built prior to 1989 are considered pre-FIRM regardless of the 1974 baseline.
Emergency Program vs. Regular Program
Not all NFIP participation is the same. Some communities enter the NFIP under the Emergency Program, which is a limited initial stage of participation.
Differences include:
-
Emergency Program coverage options are limited.
-
Preferred Risk Policies (PRPs) are not available under the Emergency Program.
-
Full benefits, including broader coverage and lower rates, are only available in the Regular Program.
Knowing which program applies is essential for understanding available insurance options.
Substantial Improvement or Damage Can Change Your Status
A property's classification can change over time based on major renovations or damage.
A structure is treated like a post-FIRM building if:
-
Improvements or repairs reach 50% or more of the building’s market value within a single year.
Consequences may include:
-
Elevated construction requirements.
-
Updated mitigation measures.
-
Higher insurance premiums.
Determinations are typically made by local building or permitting officials.
How to Find Your Community’s NFIP Status
Steps to check a community's NFIP participation and determine pre-FIRM or post-FIRM classification:
-
Visit the FEMA Community Status Lookup Tool: http://bit.ly/2s8Bapj
-
Search by community name, county, or state.
-
Identify two critical dates:
-
The NFIP entry date.
-
The FIRM effective date.
-
-
Compare the property’s construction date to the FIRM date to determine classification.
-
Verify whether the community is in the Emergency or Regular Program.
FAQs About NFIP Community Status
What if the FIRM date is earlier than 1974?
Use the community-specific effective FIRM date, not the 1974 reference year.
Are preferred rates available in the Emergency Program?
No. Preferred Risk Policies are only available in the Regular Program.
Who determines whether a property has been substantially improved?
Local permitting and building officials typically make this determination based on the 50% rule.
Conclusion: Understanding NFIP Status and Next Steps
Knowing whether a community participates in the NFIP, and identifying the effective FIRM date, clarifies insurance eligibility and risk mitigation strategies.
NFIP status affects more than policy access — it influences long-term insurance costs, building compliance requirements, and available protections.
Understanding pre-FIRM vs. post-FIRM designations, the impact of substantial improvements, and whether a community is in the Emergency or Regular Program helps in making informed insurance decisions.
