Flood insurance in South Dakota
What policyholders here actually pay, what floods have paid out, and how to pay less, from public federal records.
That is 11% above the U.S. median of $1,055; 12th highest of 51 states.
This is what existing single-family policies cost — not a quote. Your own premium depends on your building, coverage and elevation.

Am I required to carry it?
Only if your home is in a high-risk zone (A or V) and your mortgage is from a federally regulated lender, or federal help to buy or build (42 U.S.C. §4012a). Check your zone on FEMA's flood map.
66.2% of South Dakota's NFIP policies are in high-risk zones (not 66.2% of all buildings, and not an answer about your own home).
| Flood zone | Policies | Share |
|---|---|---|
| Zone AE (high-risk) | 1,285 | 50.2% |
| Zone X | 843 | 32.9% |
| Zone A (high-risk) | 347 | 13.5% |
| Zone AO (high-risk) | 53 | 2.1% |
| Other or unclassified zones | 34 | 1.3% |
Insured units by the flood zone each policy is rated in (a condo-building policy counts each unit). Outside those zones the federal requirement drops, but a lender can still require coverage.

I'm outside the high-risk zone. Do floods happen there?
Yes. 54.8% of the flood-insurance claim money paid in South Dakota went to homes outside the high-risk zones, which hold 33.8% of policies here: at least as much per policy as inside the high-risk zone.
- Claim dollars paid outside A/V zones54.8%
- Policies outside A/V zones33.8%
- Zone X median cost$1,166
Outside those zones the federal requirement drops, but a lender can still require coverage. Insured claims only, by each policy's rated zone.

How do I actually get covered — and how fast?
Buy it now: most policies start 30 days after you buy, but there's no wait if you buy it with a new or refinanced mortgage.
- Waiting period30 days
- Bought with a new or refinanced mortgageNo wait
- NFIP building limit$250,000
- NFIP contents limit$100,000
Most homeowners insurance does not cover flood damage; flood insurance is bought separately, through the federal NFIP or a private insurer. Exceptions: no wait if you buy while making, increasing, extending or renewing a mortgage, or change coverage at renewal; a one-day wait if a map revision puts the property in a high-risk zone and you buy within 13 months of the revision (44 CFR §61.11). NFIP covers up to $250,000 on the building and $100,000 on contents, which is a separate policy. To buy: call the NFIP at (877) 336-2627, go to FloodSmart.gov, or ask any licensed insurance agent. Every NFIP insurer offers the same rates.
Already flooded? Insured: report the loss to your insurance agent or company now (FEMA's steps: how to start a flood claim). Not insured: a policy bought today will not cover a flood that already happened, and FEMA disaster aid is open to people in counties designated in a federally declared disaster. Past aid paid here is in “Did the government pay homeowners after floods?” below.

What does it cost in my flood zone?
From about $1,080 a year (Zone A) to $1,166 (Zone X) here. Your zone is on your lender's flood determination or FEMA's map; find its row below.
| Flood zone | Median / yr | Policies |
|---|---|---|
| Zone AE | $1,152 | 792 |
| Zone X | $1,166 | 553 |
| Zone A | $1,080 | 172 |
Why can a high-risk zone cost less than Zone X here? Since FEMA's Risk Rating 2.0, price is set from each building's own flood risk, not its zone, and these are existing policies whose buildings differ. The reason for any one zone is not in this data.
Zones with fewer than 50 priced single-family policies are omitted. Your own premium still depends on elevation and coverage.

Why do sites quote different averages for South Dakota?
Because they measure different things. From the same FEMA records, the typical single-family home pays $1,168 a year, but the average across every policy type is $1,541.
| Measure | Amount | What it counts |
|---|---|---|
| Median cost, single-family homes | $1,168 | premium plus fees; the middle policy |
| Average (mean) cost, single-family homes | $1,310 | pulled up by a few expensive policies |
| Median premium only, single-family homes | $928 | before the federal fee, reserve fund and surcharge |
| Average premium only, single-family homes | $1,049 | the figure many sites quote |
| Median cost, every policy type | $1,199 | adds condos, rentals and businesses |
| Average cost, every policy type | $1,541 |
Published averages rarely say which of these they are, or which year. All six here come from the NFIP policies in force on July 31, 2026.

How do current premiums compare with FEMA's full-risk price?
47.8% of bills here can keep rising: they pay less than FEMA's full-risk price. Those prices step up toward full-risk each year, limited by the yearly cap. Median premium $928, full-risk $1,062 (premiums only, before fees).
- Median premium charged (before fees)$928
- Median full-risk premium$1,062
- Pay below full-risk47.8% of 1,574
Years to the full-risk price: By law most premiums cannot rise more than 18% a year (FloodSmart puts it at 18–25% for most policyholders); the cap usually does not apply to new policies, and fees and surcharges sit outside it. At the 18% cap, a policy at today's median premium ($928) would take at least about 1 annual renewal to reach the median full-risk premium ($1,062). This is the limit on how fast a bill can climb, not a forecast of any one policy.

What do floods actually pay out here?
Floods here have led to 4,016 NFIP flood claims and $61.9 million in payouts since 1978; the worst years were 2019, 2011 and 1997.
Orange bars are the three costliest years: 2019 ($15,641,198), 2011 ($14,140,205), 1997 ($8,066,936). Total paid $61,862,528: net building + contents payments by year of loss. Claims are matched by the claims dataset's county code, which may not exactly match a policy's property county.
That is 4,016 claims since 1978 against 2,562 policies in force today — a cumulative tally spanning ~49 years over a present-day snapshot, not an annual claim rate or a flood probability.

Do flood claims here actually pay out?
Most do: 74.7% of claims here paid something. The average paid claim was $20,798.
- Average paid claim$20,798
- Closed with no payment25.3%
- Claims that paid3,001
FEMA lists reasons a claim closes without payment, such as damage below the deductible, no flood as the policy defines it, or seepage and drain backup the policy does not cover. The average is over claims that paid something; a single home can file across several floods over the years.

Why do flood claims here go unpaid?
Of the 1,015 claims here closed without payment, the top reason FEMA recorded was “loss already in progress” (219 claims).
| Reason recorded | Claims |
|---|---|
| Loss already in progress | 219 |
| Damage less than the deductible | 176 |
| Not an actual flood | 102 |
The building non-payment reason on each NFIP claim closed with nothing paid. Records marked “other” or entered in error are left out.

Among named storms, Late spring storms (2011) paid out the largest total: $8.4 million across 264 NFIP flood claims.
| Storm (FEMA's name) | Claims | Total paid | Average |
|---|---|---|---|
| Late spring storms (2011) | 264 | $8.4 million | $31,882 |
| June Midwest Flooding (2024) | 61 | $5.9 million | $96,027 |
| Midwest Flooding (1993) | 86 | $723,760 | $8,416 |

Would a policy here pay to rebuild my home?
Not in full for 28.5% of insured single-family homes here: FEMA's records put their rebuilding cost above the NFIP's $250,000 building limit.
- Rebuilding cost above the building limit (of 931 policies reporting one)28.5%
- Carry the maximum building coverage50.8%
- Damage was more than the coverage (of 2,792 claims paid with a damage figure)7.3%
NFIP covers up to $250,000 on the building and $100,000 on contents, which is a separate policy. Rebuilding cost is the replacement-cost figure on each single-family primary-home policy record.

How often do the same homes flood here?
Some homes here flood again and again: 404 flood-damage applications in FEMA's disaster-aid records came from homes that flooded more than once.
- Repeat-flood damage records404
One home appears once for each declared disaster that damaged it, so this counts damage events on repeat-flooded homes, not distinct homes (FEMA says these records cannot be totaled by property). Disaster-aid applications since 2002, separate from NFIP insurance claims.

Reconciliation & data completeness
Our record counts match the API's own totals; FEMA's official policy count is not yet joined for South Dakota.
In-force count: 2,562 policy units (from 2,558 API records; condo-association records carry more than one unit). Count reconciliation (not a snapshot proof): policies: 2558/2558 fetched; claims: 4016/4016 fetched.
What this data cannot tell you
- Your own premium — it depends on elevation, coverage and deductible. We show where existing policies fall.
- Private (non-NFIP) flood insurance prices.
- Your address's exact flood zone — use FEMA's Flood Map Service Center.
- Why any one premium changes — we show the gap to full-risk, not the cause.
- A year-over-year premium trend — the in-force snapshot holds only current-term policies, so a like-for-like multi-year index isn't possible from this data. A per-effective-year median is shown only where several years of policies exist.
