Most guides to home insurance in a given state open by telling you the average premium. This one has to open by telling you that South Dakota's average premium is genuinely uncertain, and by how much.
Two current, reputable 2026 rate surveys quote South Dakota at $300,000 of dwelling coverage with a $1,000 deductible - the same coverage, the same year, the same retention. One says $3,740. The other says $2,616. That is a 43% spread, and neither figure can be thrown out on any stated ground, because both are measuring the same thing.
So the number this site records - $3,178 a year - is the midpoint of the two, and it carries an explicit verification flag. South Dakota is the only state in this dataset that does.
That is an unsatisfying way to start, and it is also the honest one. What follows treats that uncertainty as a fact about the market rather than something to paper over, because the reason for the disagreement tells you something useful: South Dakota is a small insurance market, quote-panel datasets get thin here, and a handful of carriers moving in or out of a sample moves the statewide average more than it would in Texas or Ohio.
What is not uncertain is the shape of the risk. South Dakota sits in Hail Alley. The deductible that applies to the claim you are most likely to file is almost certainly not the $1,000 on the front of your declarations page. And if a carrier declines you, this state has no backstop at all.
A note before you start: everything below is general information about how homeowners insurance works in South Dakota, not personalized insurance, legal, or financial advice. Policy forms, rates, and underwriting rules vary by carrier and by your individual circumstances - county, roof age and material, construction type, protection class, and claims history all move the answer materially. For coverage specific to your property, talk to a licensed South Dakota insurance agent; for regulatory questions or complaints, the South Dakota Division of Insurance is the state authority.
1. What home insurance actually costs in South Dakota
The reference figure is $3,178 a year for $300,000 of dwelling coverage with a $1,000 deductible.
"Dwelling coverage" - labeled Coverage A on your declarations page - is the maximum the policy will pay to repair or rebuild the structure of your home. It is the anchor number for the entire policy, and as Section 2 explains, it is also the number your hail deductible gets calculated from. $300,000 is a reference tier used so that states can be compared on the same basis. As Section 4 explains, it is very likely not the right number for your house.
For comparison, the national average at that same $300,000 tier runs roughly $2,870. So South Dakota reads about 11% above the national figure - in a state where the median home price is about $343,800, well below the national picture. That combination is the real story: South Dakota homeowners pay above-average premiums to insure below-average-priced homes.
The disagreement, in detail
Here is what the sources actually say, because you should be able to check this yourself.
- Insurance.com's 2026 state rate table: South Dakota at $3,740, quoted at $300,000 dwelling / $300,000 liability / $1,000 deductible.
- Insurify's 2026 average-cost analysis: South Dakota at $2,616, at the same nominal $300,000 level.
The gap between them is $1,124, or about 43% measured against the lower figure. For context, these same two publishers disagree by somewhere between 3% and 22% on the other states in this batch. South Dakota is the outlier, and the size of the outlier is itself a finding.
Neither is excludable. Both name the same coverage level, the same year, and the same deductible. So both are treated as reasonable and averaged, rather than one being quietly dropped because it was inconvenient.
The third source, and where it lands
A third survey helps, though it is not a clean tiebreaker because it measures a different coverage level. NerdWallet's 2026 analysis puts South Dakota at $3,965 - but at $400,000 of dwelling coverage, not $300,000. Scaling that down toward the $300,000 tier lands somewhere near $3,000, which sits inside the disputed range and modestly nearer the middle than either endpoint.
Separately, Insurify's own price-projection series - a different methodology, priced at each state's average dwelling limit rather than a fixed tier - shows South Dakota at $2,761 for 2025.
Put them together and you get a cluster running roughly $2,600 to $3,750, with a center of gravity somewhere around $3,000 to $3,200. That is the honest answer. If you want a single number to plan around, $3,178 is a defensible one. If you want to know how much confidence to put in it, the answer is: less than you would in a bigger state.
What is not in dispute
Strip out the dollar figure and the qualitative finding survives every source: South Dakota is a genuinely expensive state in which to insure a home relative to what homes here are worth, and hail is the reason.
South Dakota sits inside the Hail Alley band running from Texas up through the Plains - a band that absorbed 45% of all severe U.S. hail events between 2023 and 2025. Hail is not a tail risk here. It is the operating condition. It drives premium, it drives the deductible structure covered in the next section, it drives roof underwriting, and it drives which carriers will write you at all.
The trend
The projected change for 2026 is about +1% - Insurify's series has South Dakota moving from $2,761 in 2025 to a projected $2,775, a $14 increase. After several years of hard-market increases, that is close to flat.
Read it with the same caution as everything else in this section. On a data panel thin enough to produce a 43% disagreement about the level, a 1% reading on the change is a low-confidence number. It is a reasonable signal that South Dakota has stopped repricing sharply upward. It is not a promise about your renewal.
2. The deductible that actually applies to your most likely claim
This is the most important section in this guide, and it is the one most South Dakota homeowners have never had explained to them.
You probably have two deductibles, not one
Your policy carries a flat all-perils deductible - typically $1,000 in South Dakota, sometimes $2,000. That is the amount you pay out of pocket before the insurer pays anything. It governs fire, theft, a burst pipe, a tree through the roof, most everyday losses.
It very likely does not govern hail.
South Dakota has no coast, no hurricanes, and no named-storm deductible. What it has instead is a separate percentage wind and hail deductible, which has become a common feature of policies here for exactly the reason you would expect. Typical selections run 1% to 5% of the dwelling limit.
What that costs in real dollars
On a $300,000 dwelling limit:
- 1% = $3,000
- 2% = $6,000
- 3% = $9,000
- 5% = $15,000
Against a $1,000 all-perils deductible. At 2%, your hail deductible is six times your ordinary one.
Section 4 works out that an 1,800 square foot South Dakota home costs roughly $396,000 to rebuild. If your Coverage A limit is set correctly at that figure rather than at the $300,000 reference tier, the same percentages become:
- 1% = $3,960
- 2% = $7,920
- 3% = $11,880
- 5% = $19,800
Note what just happened: getting your coverage right - which Section 4 tells you to do - also raises your hail deductible in dollar terms, because the deductible is a percentage of the limit. That is not a reason to underinsure. It is a reason to know the number.
How common is this, actually?
Here is the best measurement available. Insurify's May 2026 hail study, drawn from its live database of carrier quotes, puts South Dakota's statewide average wind/hail deductible at 1.81% of dwelling coverage - about $5,213 in dollar terms - the fourth-highest percentage in the country, behind only Texas, New Jersey, and Massachusetts.
Two honest notes on that figure. First, the $5,213 is 1.81% of the average dwelling limit in their sample, which works out to roughly $288,000 - not 1.81% of $300,000, which would be $5,430. Second, 1.81% is a measured statewide average; the 2% used throughout this guide is the common individual selection that the average sits just under. Your policy may read 1%, or 2%, or a flat amount. Look it up rather than assuming.
Because some South Dakota policies still use a flat wind/hail deductible - commonly $1,000 or $2,000 - instead of a percentage. If yours does, you are in a materially better position on a hail claim than a neighbor at 2%, and you should know that before you shop a cheaper quote that changes it.
The trap: the percentage is of your coverage, not your damage
This catches people everywhere percentage deductibles exist. The percentage applies to the insured value of the dwelling, not to the amount of the damage. A 2% deductible on a $396,000 dwelling limit is $7,920 whether the storm did $9,000 of damage or $200,000 of damage. It is not "2% of the claim."
So a moderate hail claim can be worth almost nothing. If a storm does $10,000 of roof damage to a home with a $396,000 limit and a 2% wind/hail deductible, the insurer owes you $2,080. At 3% it owes you nothing at all, and you paid the premium anyway.
The trigger is broad - and that is the South Dakota-specific point
In coastal states, a percentage deductible usually attaches to a named storm: a hurricane or tropical storm with a name, declared by the National Hurricane Center. Those are rare events, and the high deductible is the price of covering a rare catastrophe.
South Dakota's wind/hail deductible does not work that way. It triggers on ordinary severe-thunderstorm hail and straight-line wind - which in South Dakota is not a rare event but the routine one. There is no declaration, no naming, no threshold windspeed in most forms. A June thunderstorm that puts golf-ball hail on your roof is a percentage-deductible claim.
That is the difference that matters. A 2% deductible you might face once a decade is a rational catastrophe trade. A 2% deductible you might face in any given summer is a different product entirely.
What to actually do about it
- Pull your declarations page and find the wind/hail line specifically. It is a separate line item from the all-perils deductible. If you cannot find it, call your agent and ask directly: "Do I have a separate wind and hail deductible, and is it a percentage or a flat amount?"
- Convert the percentage to dollars against your actual dwelling limit and write that number down somewhere you will find it in a hurry. The entire point of this exercise is that homeowners discover the dollar figure after the storm rather than before it.
- While you are in there, look for the roof settlement schedule too. Roof-age underwriting frequently rides alongside the wind/hail deductible in South Dakota. Section 5 covers why the two together decide most of what your policy is actually worth.
3. What a standard policy covers here - and the gaps
A homeowners policy bundles several distinct coverages:
- Coverage A - Dwelling. The structure itself.
- Coverage B - Other Structures. Detached garage, shed, fence, grain bin on a residential parcel. Usually about 10% of Coverage A automatically.
- Coverage C - Personal Property. Your belongings, usually 50% to 70% of Coverage A.
- Coverage D - Loss of Use. What it costs to live elsewhere while repairs happen. In rural South Dakota, where the nearest rental may be a long drive, this is worth more attention than people give it.
Covered perils typically include fire, lightning, windstorm, hail, theft, vandalism, explosion, weight of ice and snow, and sudden accidental discharge of water from plumbing.
Hail is covered. The question is never whether hail is covered in South Dakota - it is what deductible applies and how the roof gets settled.
Flood is never covered - anywhere, by anyone's homeowners policy
This is universal across all fifty states, not a South Dakota rule. No homeowners policy covers flood. Flood coverage is a separate purchase through the National Flood Insurance Program (NFIP) or a private flood carrier.
South Dakota homeowners frequently dismiss this because the state is landlocked and dry for much of the year. That is a mistake. The Missouri, Big Sioux, James, and Vermillion river systems all flood, spring snowmelt on frozen ground produces overland flooding that has nothing to do with a river, and Sioux Falls and Rapid City both have urban drainage that can be overwhelmed by a heavy thunderstorm cell. Being outside a mapped high-risk flood zone is a statement about a flood map, not about whether your house can flood - a meaningful share of NFIP claims nationally come from outside high-risk zones.
Note also the distinction that decides claims: water that comes from above is generally a homeowners claim; water that comes from the ground up is generally a flood claim. Rain through a hail-damaged roof is covered by your homeowners policy. The same storm's runoff coming in through the foundation is not.
Other exclusions and sublimits worth knowing in South Dakota
- Earthquake. Excluded from standard policies here as almost everywhere. South Dakota's seismic risk is genuinely low, so this is a lower priority than in Utah or Washington, but the exclusion exists.
- Sewer and drain backup. Not covered by the base policy. This is an endorsement, it is usually cheap, and in a state with spring melt and heavy summer cells it is one of the higher-value small add-ons available. Ask for it by name.
- Maintenance and wear. Insurance covers sudden accidental damage, not deterioration. A roof that failed gradually, or shingles that were already curling before the storm, gets denied - and in a hail state, "was this hail or was this age" is the single most common claim dispute.
- Cosmetic hail damage. This is the South Dakota-specific one to check for. Some carriers now attach a cosmetic damage exclusion or functional damage language to metal roofs and siding, meaning that hail dents that do not compromise the material's ability to shed water are simply not paid. If you have a metal roof, ask whether this endorsement is on your policy. It is often not obvious from the premium.
- Ordinance or law - the extra cost of rebuilding to current code rather than as originally built. Usually available as an endorsement; on older housing stock it can be a large number.
- Detached farm structures. A residential homeowners policy is not a farm policy. If you have working agricultural outbuildings, machinery, or livestock, a homeowners form will not cover them properly, and the gap is usually discovered at claim time.
4. Making sure you have enough coverage
The most consequential number on your policy is your Coverage A limit, and the most common way it goes wrong is setting it to your home's market value or your mortgage balance.
Neither is right. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Market value includes land, which does not burn and does not hail. Your mortgage balance is a financing number with no relationship at all to construction cost.
In South Dakota the error usually runs in the underinsured direction, because rebuild costs here have risen faster than the housing market has. The median home price is about $343,800. As you are about to see, that is below what it costs to rebuild a typical home in this state.
Working a real South Dakota example
Rebuilding in South Dakota runs roughly $220 per square foot - the midpoint of a published $160 to $280 band covering materials, labor, and general contractor overhead and profit, excluding land.
On an 1,800 square foot home:
- 1,800 x $220 = $396,000 to rebuild
And take the band seriously:
- At $160/sq ft: $288,000
- At $280/sq ft: $504,000
That is a $216,000 spread on the same house. Two honest limitations behind that width. First, the source publishes coarse regional bands - South Dakota shares its exact $160-$280 range with Arizona, Colorado, Georgia, Iowa, Kansas, Montana, Nebraska, and North Dakota, which makes it a Mountain/Plains regional band applied to South Dakota rather than a South Dakota survey. Second, no South Dakota building department or insurance regulator publishes a competing rebuild-cost figure to check it against.
Two other construction-cost series read South Dakota lower - $162 and $144 per square foot. Those are worth knowing about, and they are also measuring a narrower quantity: both land near a $162 national figure that does not include general contractor overhead and profit. Rebuilding after a loss does include those, because you are hiring a contractor. That is why the higher figure is used here.
The practical instruction: get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator. A per-square-foot rule of thumb is a sanity check, not an answer.
The market-value trap, worked
Suppose you own that 1,800 square foot home, it is worth roughly the state median of $343,800, and you insured it to market value because that felt like the sensible number.
Rebuild cost is $396,000. You are carrying $343,800. On a total loss you are $52,200 short, and there is no mechanism that fills that gap. You pay it, or you build a smaller house.
Now run it the other way. Suppose you insured to your mortgage balance of, say, $260,000. You are $136,000 short, and as the next subsection shows, you are also below the coinsurance threshold, which damages even your small claims.
The 80% coinsurance rule, and what a shortfall does to a partial claim
Most homeowners policies contain a coinsurance provision requiring you to insure the dwelling to at least 80% of its full replacement cost. Fall below that and the insurer does not merely cap your payout at your limit - it reduces every partial claim proportionally.
Work it on the example. Full replacement cost $396,000, so the 80% threshold is $316,800. Suppose you carry the $300,000 reference limit instead - only 5% below the threshold, and more than enough on its face for a hail claim - and a hailstorm does $60,000 of damage to your roof and siding.
- $300,000 carried / $316,800 required = 0.947
- 0.947 x $60,000 = $56,818
- Then subtract your wind/hail deductible - $6,000 at 2% of $300,000
- Net payment: about $50,818 on a $60,000 loss
You are roughly $9,200 short on a claim well inside your policy limit. Push the shortfall further and it gets worse fast. At a $260,000 limit against the same $316,800 requirement, the ratio is 0.821, the same $60,000 loss pays $49,242 before the deductible, and after a $5,200 deductible (2% of $260,000) you net about $44,042 - $16,000 short.
None of this is visible until you file.
Two endorsements worth asking about by name
- Extended replacement cost - pays a stated percentage above your Coverage A limit (commonly 25% to 50%) when rebuilding costs more than expected. In a state where a single hailstorm can put every roofer within 200 miles on a three-month backlog and push labor prices with it, this is genuinely valuable.
- Ordinance or law coverage - covers the extra cost of rebuilding to current code. On older South Dakota housing, and particularly where a roof replacement triggers current decking or ice-barrier requirements, this fills a real gap.
5. Roof age, and why it decides your premium and your payout
An honest limitation first. This site's South Dakota data file records no statewide roof-settlement standard, because South Dakota does not set one by statute. Whether your roof is settled at replacement cost or actual cash value is decided by your policy form and your carrier's underwriting rules, not by law. So rather than tell you what your policy does, here is what to go find out and why it decides the size of your check.
This matters more in South Dakota than in most states, because in a hail state the roof is the claim. The wind/hail deductible in Section 2 and the roof settlement clause in this section are the two provisions that determine most of the real-world value of a South Dakota policy, and neither of them appears in a premium comparison.
The distinction to look for: ACV versus RCV
- Replacement cost value (RCV) pays what it costs to put a new roof on today.
- Actual cash value (ACV) pays replacement cost minus depreciation for the roof's age.
That gap widens every single year. On a typical ACV depreciation schedule, a roof fifteen years into a twenty-year expected life has roughly 75% of its value depreciated away - the insurer pays about 25% of replacement cost, and you fund the rest. Your deductible then comes off the top of even that reduced amount.
Stack it against the South Dakota deductible structure
Take a $22,000 roof replacement on that $396,000 home, hail damage, with a 2% wind/hail deductible of $7,920.
- On an RCV policy: $22,000 - $7,920 = the insurer pays $14,080, you pay $7,920.
- On an ACV policy with a 15-year-old roof at 75% depreciation: the loss is valued at roughly $5,500, which is below your $7,920 deductible. The insurer pays nothing. You pay the full $22,000.
Same storm. Same house. Same nominal coverage. The difference is two lines on a policy most people have never read.
That is not a hypothetical edge case in South Dakota - it is the ordinary outcome for a homeowner with an aging roof on a percentage deductible, and it is the single most useful thing this guide can tell you to go check.
What to look for on the page
Open your policy's loss settlement section and look for:
- A "roof surfaces" or "windstorm or hail loss to roof surfacing" endorsement.
- A roof payment schedule - a table depreciating payout by roof age and material.
- Any actual cash value language applied specifically to the roof, even where the rest of the dwelling is on replacement cost. This is the most common structure, and it is easy to miss.
- Cosmetic damage or functional damage exclusions, especially on metal roofing.
Roof age also decides whether you get written at all
Roof age is a leading underwriting factor almost everywhere, and in a hail state it is frequently a gating factor rather than a pricing factor. A roof past 15 to 20 years can move you from "expensive" to "declined" - and in South Dakota, as Section 6 explains, declined means surplus lines, because there is nowhere else to go.
If your roof is near the end of its life, replacing it before your renewal is often the difference between a quote and a non-renewal notice. Ask specifically about credits for impact-resistant (Class 4) roofing - in hail states these are among the largest single discounts available, frequently in the range of a meaningful double-digit percentage of the wind/hail portion of your premium, and they also make you a more attractive risk at renewal. Ask what documentation the carrier needs to apply the credit.
6. If no carrier will write you
Here is the plain answer: South Dakota has no backstop.
This is confirmed absent rather than merely unchecked. South Dakota has no FAIR Plan and no windstorm or hail pool. It is one of the states that never established a residual property insurance market at all, and having no coastline, it has no beach or wind plan either. Published lists of states without a FAIR Plan consistently include South Dakota alongside Alaska, Arizona, Arkansas, Colorado, Idaho, Maine, Montana, Nebraska, Nevada, New Hampshire, North Dakota, Oklahoma, Tennessee, Utah, Vermont, and Wyoming - against 33 states plus the District of Columbia that do operate one.
What that means in practice
If admitted carriers decline you - most often because of roof age, prior hail or wind claims, or a rural protection-class rating - your fallback is the excess and surplus lines (E&S) market, reached through a surplus lines broker.
You should understand exactly what that means before you need it:
- E&S carriers are not rate-regulated. The South Dakota Division of Insurance does not review or approve their pricing.
- E&S carriers are not form-regulated. The policy language is whatever the carrier writes. Coverage is typically narrower, exclusions broader, and the standard consumer protections that come with an admitted policy do not attach.
- E&S policies are not backed by the state guaranty fund. If an admitted insurer becomes insolvent, the guaranty fund stands behind your claim. If a surplus lines carrier does, it generally does not. This is the protection people are least aware they are giving up.
- It generally costs more, sometimes substantially, for less coverage.
E&S is a real market and it is better than nothing - genuinely, it is how difficult risks get placed everywhere in the country. But it is a commercial fallback, not a public one.
The South Dakota Division of Insurance can still help - with different things
The Division publishes homeowners consumer guidance, maintains lists of licensed carriers and agents, and will take and investigate a complaint against an admitted insurer. Those are real services and worth using. What the Division does not do is operate an insurer of last resort. There is no state entity that has to write you.
How this should change your behavior
In a FAIR-Plan state, you can afford to be somewhat casual about your relationship with the admitted market, because there is a floor beneath you. In South Dakota there is not, and that has three practical consequences:
- Protect your claims history harder than you would elsewhere. Section 7 goes into this, but the short version is that frequency drives non-renewal, and non-renewal here has a much worse landing spot.
- Do not let your roof age past the point of insurability while you still have the option to fix it cheaply. Replacing a roof on your own schedule is far less expensive than replacing it under a non-renewal deadline.
- When you shop, do not casually drop an incumbent carrier that has been writing you for years in exchange for a modest saving from a carrier with a thinner South Dakota book. Longevity with an admitted carrier has an option value in a state with no backstop.
7. How to actually lower your premium in South Dakota
Ranked roughly by how much they move the number in this state specifically.
1. Get impact-resistant roofing credits, and get them documented. In a hail state this is the largest single structural discount available, and unlike most credits it improves your actual outcome as well as your price - a Class 4 roof takes hail better. If you are replacing a roof anyway, the incremental cost of impact-rated shingles is frequently recovered through the discount over a handful of years. Ask your carrier for the credit amount in writing before you choose materials, and ask what documentation (invoice, manufacturer certification, photos) they need.
2. Choose the wind/hail deductible deliberately, in dollars - not as a percentage. Moving from 1% to 3% on a $396,000 dwelling limit lowers your premium and raises your exposure from $3,960 to $11,880. That is a rational trade if you have $11,880 liquid and would genuinely spend it on a roof. It is a bad trade if you do not, because in this state you will probably be tested on it. Do the multiplication before you agree to a percentage.
3. Ask whether a flat wind/hail deductible is available. Some South Dakota carriers still write flat $1,000 or $2,000 wind/hail deductibles instead of percentages. If you can get one at a premium you can live with, it is usually the better structure for a homeowner without a large cash reserve, precisely because South Dakota hail claims are frequent rather than rare.
4. Get your Coverage A limit right. This is the rare adjustment that can improve your coverage and, occasionally, your price - if you have been insuring to a stale or inflated number. More often it will cost slightly more and be worth it. Either way, get an actual replacement-cost estimate rather than defaulting to market value or your loan balance.
5. Raise the all-perils deductible, not the hail one. Going from $1,000 to $2,500 on the ordinary deductible lowers your premium and only affects non-hail claims - fire, theft, water, liability-adjacent losses - which are the ones you are least likely to file. This is usually a better trade than raising the wind/hail percentage.
6. Bundle home and auto. Multi-policy discounts remain among the largest routinely available, and in a market where carrier appetite tightens after bad hail years, being a multi-policy customer measurably helps on the underwriting side too, not just the pricing side.
7. Stop filing small claims. With a $1,000 all-perils deductible and a hail deductible in the thousands, most small losses are not worth claiming anyway. More importantly, claims frequency drives non-renewal, and in a state with no FAIR Plan, a non-renewal is a materially worse event than in most of the country. Paying a $3,000 repair yourself is very often strictly better than a claim that nets you little and marks your record.
8. Ask about the credits nobody offers you unprompted. Monitored alarm and fire systems, automatic water-shutoff devices, updated electrical and plumbing on older homes, roof age itself, new-home credits, and claims-free longevity. Carriers do not always apply these automatically. Ask item by item, and ask which ones require documentation or an inspection.
9. Buy sewer backup and, if it is remotely plausible, flood. These raise your total spend rather than lowering it, and they belong on this list because the cheapest possible premium is worthless if the loss you actually suffer is not a covered peril. Sewer backup is an inexpensive endorsement. In moderate-risk flood zones, NFIP premiums are often far below what people assume.
10. Re-shop every year or two, and compare the right five things. Line them up side by side: the premium, the dwelling limit, the all-perils deductible, the wind/hail deductible - percentage or flat, and the roof settlement basis (RCV or ACV). A quote that beats yours on premium while moving your roof to actual cash value and your hail deductible from 1% to 3% is not a better quote. It is a much worse policy with a smaller number on the front page, and in South Dakota that trade is made constantly.
What to do next
If you want these numbers applied to your actual house rather than a statewide average - and given how wide South Dakota's premium range is, a statewide average is worth less here than almost anywhere - the South Dakota premium calculator estimates your annual cost from your own dwelling limit and deductible. The replacement cost calculator works out the Coverage A limit you actually need from your home's square footage using South Dakota construction costs, which is the number to check first given how far the state's median home price sits below its rebuild cost. And because the wind/hail deductible is what decides your real out-of-pocket exposure on the claim you are most likely to file, the deductible calculator converts 1%, 2%, 3%, and 5% into actual dollars against your specific dwelling limit.
All three show every figure they use and where it came from - including, for South Dakota, the disagreement between sources described in Section 1.
This guide is general information about homeowners insurance in South Dakota, based on publicly available figures current as of August 2026. The statewide average premium cited here is flagged for verification: two reputable 2026 surveys disagree by 43% at the same coverage level, and the figure used is their midpoint. This guide is not an insurance quote, a policy, coverage advice, or legal advice, and it does not reflect your individual property, county, roof age, claims history, or carrier's specific policy language. Premiums, deductible structures, roof settlement terms, and underwriting rules vary substantially by carrier and by property.
