Arizona buyer question
Do I need flood insurance in Arizona?
It depends on where the home sits on FEMA's flood maps. Here's when a lender must require it, how to check an address, and how it fits your monthly budget.
Two ways to start
- Search homes by payment
Create your free account to see all homes for sale that fit the monthly payment you're comfortable with, each with its actual property taxes, HOA dues, estimated homeowners insurance, and mortgage insurance when it applies, plus its own estimated closing costs and APR disclosure.
Opens a third-party home search site. Payments shown there are estimates to help you search, not a loan offer or rate quote. Your actual payment depends on price, down payment, credit, taxes, insurance, HOA, and loan program.
- Get pre-qualified (Apply now) (opens in a new tab)
Get pre-qualified with Pam Messina at Rebel Rate Mortgage. Once you're pre-qualified, Pam can update the maximum monthly payment and total funds to close in your home search, so the homes you see match what you qualify for. If you'd like, she can also give you a free, no-obligation introduction to a real estate professional so you can start touring homes.
Opens Rebel Rate Mortgage's secure online application (my1003app.com) in a new tab. Pre-qualification isn't a loan approval or a commitment to lend; approval depends on underwriting, verification of your information, and the property.

The short answer
Quick answer: If the home is in a FEMA special flood hazard area and you get a federally regulated or federally backed mortgage, federal law requires flood insurance on the building for the life of the loan. Outside those zones it's optional. Standard homeowners policies generally don't cover flooding, so check the address on FEMA's flood map before you offer.

When is flood insurance required?
Under 42 U.S.C. §4012a, federally regulated lenders may not make, increase, extend or renew a loan secured by a building in an area FEMA has identified as having special flood hazards, in a community where flood insurance is available, unless the building is covered by flood insurance for the term of the loan. Federal agency lenders follow the same rule. The FDIC's version of the rule (12 CFR §339.3) sets the minimum coverage at the lesser of the loan balance or the maximum coverage available for that type of property, and notes that flood insurance covers the building and personal property securing the loan, not the land.
Lenders must also accept private flood insurance that meets the federal definition, so a policy from the National Flood Insurance Program isn't your only option.
Will I be told before I sign?
Yes, if the lender determines the home is in a special flood hazard area. 42 U.S.C. §4104a requires lenders to notify the buyer in writing a reasonable time before the loan documents are signed. Don't wait for that notice: check the address yourself during your inspection period so the cost doesn't surprise you late in escrow.
How do I check an Arizona address?
- FEMA Flood Map Service Center. Search the address at msc.fema.gov to see the effective flood map and zone.
- Your county flood control district. In Maricopa County, the Flood Control District offers an "Am I in a floodplain?" lookup for FEMA-designated 100-year floodplains. It notes that floods happen here despite the desert, especially during summer monsoon and winter storms.
- Ask the seller and read the disclosures. The Seller's Property Disclosure Statement asks about flooding and drainage.

The 30-day waiting period
A new National Flood Insurance Program policy generally takes effect 30 days after you apply and pay (42 U.S.C. §4013(c)). The law makes an exception when the purchase is tied to making, increasing, extending or renewing a loan, so a policy bought for your closing can start at closing. If you're buying outside a flood zone and want coverage anyway, apply early.
Does homeowners insurance cover floods?
Generally, no. Flood coverage is a separate policy. See what affects homeowners insurance cost in Arizona for the rest of the insurance picture. Ask an insurance agent for a quote for the specific address. We don't publish premium estimates because they depend on the building and its flood risk.
How flood insurance fits your monthly budget
When it's required, the premium is usually collected in your escrow account along with property taxes and homeowners insurance, so it raises the monthly payment. Two homes at the same price can have very different payments if one needs flood coverage.
