Flood Insurance Outside a High-Risk Flood Zone (Zone X) in Florida

Zone X is FEMA's label for areas outside the Special Flood Hazard Area, the zones with a 1 percent chance of flooding in any given year. Shaded Zone X is a moderate flood hazard area, between the limits of the base flood and the 0.2-percent-annual-chance flood, and unshaded Zone X is a minimal flood hazard area, higher than the 0.2-percent-annual-chance flood. FEMA's own advice is that "flooding can happen anywhere" and that flood insurance "is available to all property owners, renters, and business owners," while a typical homeowners policy does not cover flood (FEMA glossary; FEMA; Florida CFO).

What Zone X means

FEMA's flood maps divide an area into zones by how likely flooding is. The Special Flood Hazard Area (SFHA) is the area with a 1 percent chance of being equaled or exceeded in any given year, also called the base flood or 100-year flood. Zone X is what the glossary lists for the areas outside it:

• Zone X (shaded), also labeled Zone B. A moderate flood hazard area, "between the limits of the base flood and the 0.2-percent-annual-chance (or 500-year) flood."
• Zone X (unshaded), also labeled Zone C. A minimal flood hazard area, "outside the SFHA and higher than the elevation of the 0.2-percent-annual-chance flood."

Both are on the FEMA glossary page for flood zones (FEMA glossary). Being outside the SFHA is a statement about the map's categories. It is not a statement that water cannot reach a home. FEMA's page for homeowners says "Even if you are not located in a high-risk flood zone, remember that flooding can happen anywhere," and for more specific information about a property's flood risk it suggests contacting an insurance agent at a participating National Flood Insurance Program provider (FEMA).

Our broader guide to flood insurance in Florida covers NFIP and private flood policies, coverage limits and exclusions.

Is flood insurance required in Zone X

Two different rules are in play, and neither is based on Zone X itself:

1. Federal rule for mortgages. FEMA says federally regulated or insured lenders must require flood insurance for buildings in a Special Flood Hazard Area that secure a federally backed loan (FEMA). A home in Zone X is outside that area, so this federal rule does not reach it.
2. Your lender and your insurer. A lender or insurer can have its own requirements. The Consumer Financial Protection Bureau tells buyers who are shopping for homeowner's insurance that "Homeowner's insurance typically does not cover damage from floods" and that a separate policy is needed if flooding is a risk for the home (CFPB).

Citizens Property Insurance is a separate case. State law requires Citizens to require flood coverage on most of its personal residential policies on a schedule by dwelling replacement cost, with all other policies reaching the requirement on January 1, 2027 (s. 627.351(6)(aa), Fla. Stat.). Citizens policies without wind coverage and condominium unit-owner policies are exempt. Our Citizens guide and the dates table in the flood guide go through it.

In a bulletin dated October 1, 2026, Citizens says new language takes effect for new and renewal business on December 1, 2026: the declarations page will say that, where Florida law requires flood insurance and Citizens verified it, the policy "may not provide coverage for any wind related losses when a wind loss occurs" if the required flood coverage was not in force on the date of loss (Citizens, Personal Lines: 2026 Form Changes). A Citizens policyholder should read that notice in the renewal package.

Broward County's FEMA maps, effective July 31, 2024

Broward County's flood zone maps page says FEMA's new Flood Insurance Rate Maps ("FIRMs or flood maps") "are effective as of July 31, 2024," and asks residents to review the maps and "see how your property may be impacted." For more information about the July 2024 FEMA flood zone maps, the County points to your Community Floodplain Manager (Broward County, Flood Zone Maps). We read the County's page as archived on January 6, 2026, because the live page blocks automated reading; the wording may since have been updated.

Why that matters for a Zone X home: a zone assigned years ago may not be the zone on the maps now in effect. The only way to know is to look up the address. See our hubs for Pembroke Pines, Miramar, Fort Lauderdale and Hollywood for local flood information.

How to look up an address on FEMA's Flood Map Service Center

The Map Service Center is FEMA's public portal for flood maps, at msc.fema.gov.

1. Open the Flood Map Service Center and use Address Search, which "allows you to search by specific address or location" (FEMA Map Service Center, how-to).
2. Enter the street address of the home, not just the city or ZIP code.
3. Find the flood map for the area in the results and open it with the View button. FEMA's how-to page explains that "to create a FIRMette, you must first find a flood map, and then click the View button associated with that flood map."
4. Read the zone label for the property on the map, and note the map's effective date. Preliminary maps cannot be used to create a FIRMette.
5. If the map is hard to read or the address sits near a zone boundary, ask your agent, your lender or the local floodplain manager.

FEMA's FAQ on finding a current flood map also points to the Address Search feature, which lets you "search by specific address or location" (FEMA).

The 30-day wait

FloodSmart, the NFIP's consumer site, says a new policy goes into effect 30 days after the date of purchase and lists exceptions (FloodSmart):

• no wait when you buy flood insurance while making, increasing, extending or renewing a mortgage;
• no wait when you change your coverage while renewing your policy;
• a one-day wait if the property is in a newly designated high-risk flood zone and you buy within 12 months of the map update;
• a one-day wait if a flood is caused or worsened by a wildfire on federal land and you buy within 60 days of the wildfire containment date.

The Florida CFO's guidance says there is generally a standard 30-day waiting period for any type of flood policy (Florida CFO).

Worked example: the wait in Zone X

Made-up dates. A homeowner with no mortgage, whose home is in Zone X, buys a flood policy on June 1. Coverage goes into effect 30 days after the purchase date, July 1. A flood on June 20 would fall inside the waiting period. The mortgage exception does not apply because the purchase is not tied to a loan, and the newly-designated-zone exception does not apply because the home is not in a newly designated high-risk zone.

Elevation certificates and Zone X

An elevation certificate is an NFIP form. FEMA says it "can be used to provide elevation information necessary to ensure compliance with community floodplain management ordinances, to inform the proper insurance premium, and to support a request for a LOMA, CLOMA, LOMR-F, or CLOMR-F," and that it may be used for buildings "in any flood zone." The form also says use of the certificate "does not provide a waiver of the flood insurance purchase requirement" (FEMA, NFIP Elevation Certificate and Instructions). Whether an elevation certificate would help a particular home is a question for an agent or a licensed surveyor.

Zone X questions

Talk to an agent

Your agent can look up the address with you, explain NFIP and private flood options and tell you when coverage would start. Our flood insurance page describes the coverage we place, and our homeowners insurance page shows how it fits with a homeowners policy.
