A standard homeowners insurance policy covers certain types of water damage, but it won’t pay for damage from natural flooding. For that reason, mortgage lenders often require separate flood insurance for homes in special flood hazard areas.
There are two main ways to get flood insurance:
National Flood Insurance Program (NFIP): The NFIP is the main flood insurance provider in the U.S., accounting for the vast majority of residential flood policies nationwide.  The policies are written and backed by the Federal Emergency Management Agency (FEMA), but sold by private insurance companies.
Private flood insurance: This is flood insurance that is both written and funded by private insurance companies. While private flood insurance only makes up a tiny fraction of the market, it’s become an increasingly popular and occasionally cheaper alternative to the NFIP.
Additionally, private flood insurance tends to have a wider array of coverage options and higher limits of protection than the NFIP plan.

What is private flood insurance?
Private flood insurance covers your home and belongings from damage caused by outside flooding. But what makes it different from FEMA flood insurance is that policies aren’t backed by the federal government. The insurance company is responsible for managing its own risk and paying out claims.
While it only accounts for around 5% of the residential flood insurance market, the number of people turning to private flood insurance instead of the government program appears to be on the upswing. In fact, private flood insurance premiums grew 71% from 2016 to 2018, and 15 states experienced over 100% growth in premiums during that span. 
There are a couple of reasons for why private flood insurance is becoming more popular
Insurance companies no longer view flood insurance as an untouchable risk. Company models for determining the flood risk of each home are more sophisticated, and the third-party firms in charge of creating these models are getting better at predicting floods. This has incentivized more investment in private flood insurance, and as a result, companies are expanding and pouring more resources into new markets.
It’s important to note that FEMA is over $20 billion in debt. The unpredictability of the government program has both insurance policymakers and policyholders searching for another answer.

What is the National Flood Insurance Program?
The NFIP was established by the federal government in the late 1960s to provide flood insurance and establish floodplain standards in communities across the country. Around 90% of residential flood insurance in the U.S. is provided by the NFIP.
Policies are primarily sold through its Write Your Own (WYO) program to residents who live in an NFIP-participating community. The WYO program basically allows private insurance companies to write and service government flood insurance using their own name and branding. In fact, you can generally purchase NFIP coverage from your home insurance provider.
FEMA flood insurance includes two types of coverage with their own separate out-of-pocket deductible.
Building property coverage: Pays to repair flood damage to your home or garage. The maximum building coverage limits for residential property is $250,000, which is often too low for more expensive homes.
Personal property coverage: Pays to repair or replace flood-damaged furniture, electronics, appliances, and other stuff you own. The maximum personal property coverage limit is $100,000.
Until recently, if you had a federally-backed mortgage and you lived in a high-risk flood zone, your mortgage company could require you to buy flood insurance exclusively through the NFIP. But as of July 1, 2019, lenders are required to accept private flood insurance as long as the policy includes at least the same quality coverage as the NFIP option.

Private flood insurance vs. NFIP: Which is better?
Since private flood insurance isn’t subject to the same restrictions and regulations as government flood coverage, insurers are able to offer coverage options not available through the NFIP. This includes payments for temporary living expenses — like hotel stays and restaurant meals — and coverage for personal belongings in your basement.
Private flood insurance also often offers higher protection limits for your home and belongings, and policy enhancements like replacement cost personal property coverage, limiting your out-of-pocket expenses after a flood loss.
Private flood insurance
Maximum home rebuild limit
Typically up to $500,000 or higher
Participating communities in all 50 states
May be limited in higher-risk areas
As little as two weeks
Accepted by mortgage lenders
Replacement cost building coverage
Replacement cost contents coverage
Loss of use coverage
Loss avoidance coverage (sandbags, etc)
Debris removal coverage
Additionally, private flood insurance has a shorter waiting period, which is the amount of time it takes for your policy to take effect after you’re approved for coverage. This makes it a preferred option during hurricane season for residents who need coverage right away.
But there are some downsides to private flood insurance as well. You typically have to pay a higher out-of-pocket deductible on claims, and your policy can be canceled or nonrenewed if your insurer thinks your home is too high risk. With NFIP flood insurance, you generally don’t have to worry about getting dropped from your policy.
But if you feel you’re being charged too much for NFIP coverage or you’re interested in higher coverage limits for your house and belongings, it may be worth turning to private flood insurance instead. In fact, a 2017 study by Milliman found that 77% of single-family homes in Florida, 69% in Louisiana, and 92% in Texas could all see cheaper premiums with private flood insurance.

Case study: What it's like filing an NFIP flood insurance claim
We spoke to one homeowner who filed an NFIP flood insurance claim after Hurricane Sandy about his experience with the NFIP, and the changes FEMA has made since to prevent the issues brought on by the historic storm.
Maurice Gallagher and his wife owned and lived in a five-bedroom duplex near the Great Egg Harbor Bay in Ocean City, New Jersey, in late October of 2012 when Hurricane Sandy threatened the New Jersey coastline.
After the storm hit, Gallagher, and many of his neighbors, called their flood insurance company. “It ended up being about three feet to three-and-a-half feet of water that got inside. I called my flood insurance company over the phone. I had to contact my homeowners insurance company too because I had roof damage.”
Why he had to file two insurance claims
Flood insurance only covers flood damage, but homeowners insurance can cover lots of other types of damage, including wind damage, which is why Gallagher had to file two separate claims — one with his flood insurance provider for the flooding, and one with his homeowners insurance for everything else.
“I’ve had flood insurance since the day I bought the house,” Maurice explained, “Through the government.” Because Gallagher lived in a high-risk flood zone along the Atlantic coast, he was eligible for coverage through the NFIP. Luckily for Gallagher his home wasn't left uninhabitable. Since the NFIP doesn't offer loss-of-use coverage (unlike private flood insurance) he would've had to foot the bill himself to live elsewhere while his home was being repaired.
How long it took to get his NFIP claim payout
Gallagher eventually received a claim payout, but it took months. After Hurricane Sandy, the NFIP had a backlog of flood insurance claims, resulting in New Jersey’s Congressional delegation sending a letter to FEMA after South Jersey residents hadn’t received their payouts three months after hurricane originally hit. 
The hardships that homeowners faced after Hurricane Sandy even led lawmakers and advocates to reconsider how the government handles flood claims and flood zoning to prevent such delays from happening again.

Who is eligible for private flood insurance?
Anyone is eligible for private flood insurance. That being said, it might be harder to find coverage if you live in a high-risk flood zone since private insurance companies might not want to take on the risk. If that's the case, consider purchasing a policy through the NFIP. While they have lower coverage limits, they write policies nationwide for homes in all types of flood zones.
