Under the National Flood Insurance Program, there is a big difference between how your claim is paid if the flooded property is your primary or non-primary home. While the property coverage may differ, contents are covered Actual Cash Value (ACV) either way.
Two Labels: Primary Residence and Principal Residence
While they sound very similar, the NFIP splits these terms into two entirely different categories based on the time you spend in the home.
Primary Residence (The 50% Rule for Pricing): This is a term used strictly for policy rating and premiums. To be categorized as primary, you or your spouse must live in the home for more than 50% of the 365 days following the policy’s effective or renewal date. If you meet this mark, you avoid non-primary surcharges and maintain standard primary rating tiers.
Principal Residence (The 80% Rule for Claims): This is a term used strictly to determine loss settlement when you file a claim. To qualify for Replacement Cost Value (RCV)—meaning the insurance company pays to rebuild your home without deducting for age or depreciation—the home must be your principal residence. Under the Standard Flood Insurance Policy (SFIP), this means you or your spouse must have lived in the dwelling for at least 80% of the 365 days immediately preceding the flood loss.
Primary Residence vs Non-Primary Residence – Occupancy Thresholds
For (NFIP) purposes, a primary residence is a single-family building or residential unit that you or your spouse live in for more than 50% of the 365 days following the policy’s effective or renewal date. A non-primary residence (often called a secondary or non-primary residential property) is any residential building that will not be lived in by the policyholder or spouse for more than 50% of that year.
- Primary home: The house you actually live in as your main residence. For NFIP rating, that generally means you or your spouse live there more than 50% of the year. A person can have only one primary residence.
- Non-primary home: A second home, vacation house, rental, or investment property—anywhere you do not mainly live.
- A house can be rated “primary” and still fail the 80% test at claim time – The house was rated primary. At claim time it fails the 80% occupancy test. The building claim is then paid at actual cash value (minus depreciation), not replacement cost.
FEMA’s pricing system (Risk Rating 2.0) factors in occupancy type. Non-primary residences often do not qualify for certain subsidies or rate caps that protect primary homes, meaning premiums can be significantly higher. And this distinction–primary vs non-primary–matters a lot when it comes to claims pay outs.
To qualify for Replacement Cost Value (RCV) on building repairs under a Standard Flood Insurance Policy, stricter occupancy rules often apply (traditionally requiring the owner to live there 80% of the year as a “principal” residence).
Properties classified strictly as non-primary or secondary residences are often settled at Actual Cash Value (ACV), which accounts for depreciation.
Contents are always Actual Cash Value under NFIP. No replacement-cost option. Max $100,000.
Example
$80,000 building damage with $25,000 depreciation:
- Qualifying primary, adequately insured → near $80,000 before deductible
- Non-primary → near $55,000 before deductible
Flood insurance from a private carrier (not the NFIP) can pay replacement cost on a second home and sometimes on contents, but those terms vary by carrier.
What is the same for both?
- Building cap $250,000
- No additional living expenses
- Increased Cost of Compliance up to $30,000 if eligible
- Same basic exclusions
Take away
These terms can be confusing. Look at your policy and be sure that it accurately reflects your property’s occupancy and your usage. FEMA’s Risk Rating 2.0 makes these distinctions just as important as your flood zone, since the RR2.0 doesn’t weigh the flood zone at all, but instead considers the type of construction, use, occupancy and proximity to water (not technically the zone).
As always, make an appointment with your insurance agent to ensure that your largest investment is properly covered.
