Flood is the coverage Texans are most likely to need and least likely to have — partly because the pricing has been genuinely confusing, and partly because a lot of people believe they're already covered.
The pricing confusion has a specific cause. FEMA replaced a rating system that had barely changed since the 1970s, and most of what's written online still describes the old one. If you've read that your flood premium depends on your flood zone, you've read something that stopped being true in 2023.
I'm a Farmers agent in Richardson, and I can write flood coverage for Texas households. Here's how the cost actually works now.
Why doesn't my homeowners policy cover flood?
The short answer: Because flood is excluded from standard homeowners forms — everywhere, not just in Texas. It's a separate policy, and there's no version of your home policy that adds it.
This is the misunderstanding that costs people the most, and it surfaces at the worst possible moment. A standard Texas homeowners policy covers a great deal — fire, wind, hail, theft, many kinds of sudden water damage from inside the house. It does not cover flood, meaning rising surface water entering your home from outside.
The distinction matters and it's genuinely confusing. A burst pipe upstairs is usually covered. Water coming in over the threshold during a heavy storm is not. Same water, same carpet, entirely different outcome — and the difference is where the water came from.
Flood coverage comes from a separate policy, either through the National Flood Insurance Program, which FEMA administers, or from a private flood insurer. Either way it's bought separately and priced separately. That also means the flood premium sits on top of your home premium rather than inside it, so budget the two separately — what Texas home insurance costs covers the other half of that number.
What does flood insurance actually cost in Texas?
The short answer: There is no reliable Texas average, because FEMA now prices each property individually rather than by flood zone. Any confident statewide figure describes a system that ended in 2023.
You'll find plenty of Texas flood insurance averages online. Most trace back to sources with a commercial interest, and nearly all of them present figures organized by flood zone, which is the part that's now obsolete.
Here's the honest position. FEMA itself publishes state-level profiles describing how Risk Rating 2.0 affected policies in each state, along with exhibits showing what flood insurance costs for a single-family home under the current approach. Those are the figures worth looking at, because they come from the entity actually setting the rates.
What I won't do is quote you a Texas average from a source I can't stand behind, then let you anchor on it. Two houses on the same Richardson street can price very differently under the current methodology — because the methodology is now about the house, not the neighborhood.
How does FEMA calculate the premium now?
The short answer: From your individual property — distance to water, the type and frequency of flooding, your foundation, your first-floor height, prior claims, and what it would cost to rebuild.
Risk Rating 2.0 was implemented in phases from October 1, 2021 through April 1, 2023, and it replaced a system that classified properties by flood zone, occupancy type, and elevation relative to base flood elevation. The old approach didn't account for an individual property's actual risk or the cost to rebuild it, and it recognised only two sources of flood risk — neither of which captured the inland flash flooding that actually threatens most of North Texas.
Under the current approach, premiums are calculated from specific features of the individual property:
| Factor | Old methodology (pre-2023) | Risk Rating 2.0 |
|---|---|---|
| Flood zone on the map | Primary price driver | Not used for pricing |
| Cost to rebuild your home | Ignored | Directly priced |
| Distance from water | Not measured | Property-specific |
| Types of flooding considered | Two | Multiple, including flash flooding |
| Foundation and first-floor height | Elevation vs. BFE only | Foundation type and floor height |
| What maps still control | Mandatory purchase requirement and floodplain management — not your premium | |
Distance from water
Not which zone you're in — how far your structure actually sits from a flooding source. This is a property-specific measurement rather than a map boundary.
Type and frequency of flooding
The current approach accounts for multiple flood types rather than the two the old system recognized — which is why inland flash-flood exposure is now priced rather than ignored.
Foundation type
Slab, pier and beam, basement, crawlspace. How your house meets the ground changes how water reaches it and what it damages.
First-floor height
The height of the lowest floor relative to base flood elevation. This is often the single most influential structural factor, and it's the one mitigation can change.
Prior claims
Flood claim history on the property carries forward, in the same way claim history follows an address on a homeowners policy.
Replacement cost value
What it would cost to rebuild the structure. The old system ignored this entirely, which is a large part of why it produced results that felt arbitrary.
The consequence people find hardest to absorb: flood zones are no longer used to calculate your premium. Flood Insurance Rate Maps still exist and still matter — they govern the mandatory purchase requirement for federally backed mortgages and they drive floodplain management — but being remapped into a different zone does not by itself change what you pay.
That's a genuine improvement in fairness, and it also means a lot of received wisdom is now wrong. "I'm in Zone X so flood insurance is cheap" and "they remapped us so our rates will spike" are both statements about a system that no longer operates.
What is the glide path, and how does the 18% cap work?
The short answer: If your full-risk rate is higher than what you pay today, FEMA can't jump you there — most annual increases are capped at 18% until the full rate is reached.
When Risk Rating 2.0 arrived, some properties were found to be paying less than their full-risk rate. Rather than repricing those overnight, FEMA phases them up.
FEMA can't move you there at once. With annual increases capped at 18%, year two is about $826, year three about $975, year four about $1,150, and year five reaches the $1,300 full-risk rate — where the increases stop.
So the climb is roughly four renewals, not an open-ended escalation. That's a very different thing to plan around, and it's why the question worth asking your agent is not "will it keep going up" but "how far am I from full risk?" Figures are illustrative; your own starting premium and full-risk rate are specific to your property.
Two practical implications. First, if your flood premium has been climbing steadily, that's likely the glide path rather than anything about your property changing — and it has an endpoint. Second, the increases stop once you reach the full-risk rate, which is worth knowing if you've been assuming the climb is open-ended.
Worth asking your agent directly: am I on the glide path, and if so, roughly how far from the full-risk rate am I? That's a very different planning conversation than an indefinite increase.
Do I need flood insurance if I'm not in a flood zone?
The short answer: Being outside a high-risk zone means your lender doesn't require coverage. It doesn't mean water can't reach your house.
This is where North Texas gets misunderstood. We're inland, we're not thinking about flooding most of the year, and the mental model many people carry is that flooding happens to properties near rivers or the coast.
What actually happens here is flash flooding. Heavy rain arrives faster than storm drains and creeks can move it, water goes where the ground sends it, and low-lying properties take on water that has nothing to do with a mapped floodplain. Drainage patterns also change as areas develop — new construction upstream can redirect water toward properties that never had a problem before.
The mandatory purchase requirement — which is what flood maps still drive — is a lending rule, not a risk assessment of your particular house. Plenty of properties outside high-risk zones flood, and their owners generally discover the homeowners exclusion afterward rather than before.
My honest position for a Richardson household: get the quote. Under the current approach, a property with genuinely low risk generally prices accordingly, so finding out costs you nothing but a conversation. What I'd avoid is deciding you don't need it based on a zone designation that no longer even determines the price.
How can I lower what I pay?
The short answer: Community Rating System discounts, deductible choice, and — where it's feasible — mitigation that raises your lowest floor.
- Check your community's CRS class. Communities participating in the Community Rating System earn NFIP rate discounts of 5% to 45% based on their classification. Because the current approach doesn't use flood zones, that discount is applied uniformly to every policy in the participating community, whether or not the structure sits in a Special Flood Hazard Area. This is free money if your community participates and you didn't know.
- Choose the deductible deliberately. As with any deductible on a Texas policy, a higher one lowers premium — and as always, only take one you could actually fund.
- Understand what first-floor height does. Elevation relative to base flood elevation is one of the strongest structural factors. For most existing slab homes that isn't something you'll change, but it matters for new construction, additions, and decisions about mechanical equipment placement.
- Ask about documentation. Property-specific data drives the rate now, so making sure your property's characteristics are recorded accurately is worth doing rather than assuming.
- Compare NFIP against private options. More on that below — the answer isn't automatic in either direction.
Should I use NFIP or a private flood policy?
The short answer: Both are legitimate. NFIP is standardized and available in participating communities; private policies sometimes offer higher limits or different terms. It's worth comparing rather than defaulting.
The National Flood Insurance Program is the default for most households and the only option in some situations, particularly where a lender's requirement is involved. Its coverage limits and terms are standardized, which makes it predictable.
Private flood insurers have grown as an alternative, and they sometimes offer higher coverage limits than NFIP maximums, different waiting periods, or terms that fit a particular property better. They can also be more selective about which properties they'll write.
I'm not going to tell you one is universally better, because it depends on the property, the coverage you need, and what's actually available to you. What I'd push back on is choosing without comparing — this is a coverage where the two markets can produce meaningfully different answers for the same house.
The bottom line
The short answer: Your home policy doesn't cover it, the price now depends on your specific property rather than a zone, and there's a 30-day waiting period — so this is a decision to make on a quiet week.
Flood pricing stopped being about maps in 2023 and became about houses. That's better for homeowners, but it means most of what's written about flood insurance costs describes a system that no longer exists — including the confident Texas averages organized by flood zone.
What's true now: your premium reflects your distance to water, your foundation, your first-floor height, your claim history, and your rebuild cost. If you're on the glide path, increases are capped at 18% annually and they end when you reach the full-risk rate. And if your community participates in the CRS, you may already be earning a discount between 5% and 45%.
The only way to know your number is a quote on your address. That's free, it takes a few minutes, and the 30-day waiting period is a good reason not to leave it until the sky looks wrong. Send me your address and I'll run it — I'm in Richardson, I do this in English and Spanish, and there's a $10 e-gift card just for letting me prepare the quote.
