Most state home insurance guides are organized around a deductible. There is a percentage buried in the policy, it applies to the claim you are most likely to file, and nobody discovers the dollar amount until after the storm.
Idaho is not that state, and the reason is more unsettling than the deductible.
Idaho has no hurricane deductible — it is landlocked, and it does not appear on the Insurance Information Institute's list of nineteen states plus the District of Columbia that use hurricane or named-storm deductibles. It also does not have the Plains-state pattern of routine percentage wind and hail deductibles that Iowa, Illinois, Indiana and Kansas now do. The flat $1,000 deductible on your declarations page really is, for most Idaho homeowners, the deductible that governs your claim.
So where did Idaho's catastrophe risk go? It went into underwriting. Idaho's real catastrophe exposure is wildfire, and the market is not pricing wildfire through a special deductible. It is pricing it through who gets a policy at all. The number of carriers writing homeowners business in Idaho reportedly fell from about 91 in 2023 to roughly 22 to 25 by 2025. Homeowner non-renewals went from about 3,900 in 2022 to 27,798 in 2023.
And Idaho is one of the minority of states with no FAIR plan — no state-backed insurer of last resort at all.
Put those three facts together and you get the actual shape of Idaho home insurance. Your policy is comparatively cheap and comparatively simple, and the risk you carry is not a five-figure deductible. It is the risk of receiving a letter saying your coverage ends in ninety days, in a state where there is no public backstop waiting for you.
This guide works through what the policy costs, what applies to which claim, how much coverage you actually need, and — the section most Idaho homeowners should read twice — what happens when nobody will write you.
A note before you start: everything below is general information about how homeowners insurance works in Idaho, not personalized insurance, legal, or financial advice. Policy forms, rates, and underwriting rules vary by carrier and by your individual circumstances — wildfire risk score, distance to a fire station, roof material and age, construction type, and claims history all change the answer materially. For coverage specific to your property, talk to a licensed Idaho insurance agent; for regulatory questions or complaints, the Idaho Department of Insurance is the state authority.
1. What home insurance actually costs in Idaho
The reference figure is $2,076 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 Section 4 explains why the $300,000 used here is almost certainly not the right number for an Idaho home. It is a reference tier, chosen so that all fifty states can be compared on the same basis.
Against the national picture, Idaho is a below-average-cost state. The two national averages published on that same $300,000 tier are roughly $2,872 (Insurance.com) and $3,057 (Insurify). At $2,076, Idaho runs about 72% of the lower of those two.
That is the honest headline, and it is real. Idaho is not an expensive state to insure a house in. But the number deserves three qualifications, because Idaho is a small market and the published data is genuinely thinner here than in the large states.
The sources disagree by 39%
The two current rate tables that quote Idaho on the same $300,000 dwelling / $1,000 deductible basis are not close. One puts Idaho at $2,412; the other puts it at $1,740. That is a 39% spread on the same nominal package. For a market Idaho's size that gap probably says more about thin sampling than about a real dispute over Idaho's rate level, so neither is discarded and both are averaged, giving $2,076.
Two further reads at different coverage tiers bracket that figure the way they should: $1,675 at a lower $250,000 tier sits below it, and $2,195 at a higher $400,000 tier sits above it. That is a consistent pattern rather than a contradiction, and it is mild corroboration that $2,076 is in the right neighborhood.
The check that matters most is the regulator's
Aggregators publish quoted rates. The Idaho Department of Insurance runs a data call against carriers' actual in-force books, and its numbers tell a different story about direction even while agreeing about level.
The Department's homeowners data call reported a statewide average annual premium of:
- $1,308 in 2022
- $1,468 in 2023 — up about 12%
- $1,798 in 2024 — up about 22%
Those figures are not directly comparable to a fixed $300,000 tier, because they average whatever dwelling limits Idaho homeowners actually carry rather than a standardized package. But they reconcile with the $2,076 used here: $1,798 in 2024, growing at anything close to the 12% to 22% pace that same series shows, lands somewhere in the $2,000 to $2,400 range by 2026. That brackets $2,076 neatly.
The trend number, and why this guide records its own dissent
The most recent published year-over-year figure for Idaho is a mild +2% for 2026, against a national +4% in the same report.
Treat that skeptically. It is the only current published projection, which is why it appears here, but it sits very awkwardly against everything else on this page. The Department of Insurance's own series shows roughly +12% then +22% in consecutive years. The same publisher that now projects +2% separately reported a 17% Idaho increase for 2024.
A market that raised prices by double digits two years running while shedding roughly two-thirds of its carriers is not obviously a +2% market. The honest reading is that +2% is one publisher's forward projection on its own basis — each state priced at its own average dwelling limit rather than a fixed $300,000, so its dollar levels are not comparable to the figures above — and it may substantially understate what an Idaho homeowner in a wildfire-exposed foothill area sees at renewal. If your renewal comes in at +20%, you are not an outlier and you have not done anything wrong.
2. The deductible that actually applies to your most likely claim
In most of the states covered on this site, this is the section where a percentage deductible turns out to be three to fifteen times larger than the number on the declarations page. In Idaho, it is not. This is one of the genuinely simpler deductible structures in the country, and it is worth understanding exactly what that does and does not mean.
There is no catastrophe deductible in Idaho — and that was checked, not assumed
Two things were verified specifically:
- No hurricane or named-storm deductible. Idaho is absent from the Insurance Information Institute's list of nineteen states plus DC that use them. That is exactly what you would expect for a landlocked interior state.
- No routine percentage wind/hail deductible. This one matters more, because Idaho does get hail and wind, and those claims are becoming more frequent. But no source documents a separate percentage wind/hail deductible as the common structure on an Idaho homeowners policy — in clear contrast to the well-documented Midwest pattern in Iowa, Illinois, Indiana and Kansas, where it now is the norm.
What that actually means for you
Your $1,000 all-perils deductible — the amount you pay out of pocket before the insurer pays anything — governs the great majority of Idaho claims. Fire, including wildfire. Wind. Hail. Theft. A burst pipe. Vandalism. One deductible, one number, and it is the number printed on your policy.
That is a real advantage and it is worth naming plainly. An Iowa homeowner filing a hail claim on a $300,000 dwelling limit faces $3,000 to $15,000 out of pocket. A Kansas homeowner faces $6,000 at a typical 2%. An Idaho homeowner filing the same claim faces $1,000. On the claims Idaho homeowners actually file, Idaho policies are structurally more generous than most of the interior West and Midwest.
Two exceptions you can still walk into
Neither is the Idaho norm, but both exist and both are worth checking for by name:
- Percentage-of-dwelling deductibles are offered as an option by some Idaho carriers, alongside the usual flat menu of $500, $1,000 and $2,500. If you chose one to lower your premium — or if an agent selected it for you — you have a percentage deductible even though your state does not require one. On a $300,000 limit, a 1% option is $3,000 and a 2% is $6,000.
- Homes placed with surplus-lines carriers in high wildfire-risk foothill areas can carry a separate wildfire deductible. If you have been non-renewed and placed with a non-admitted carrier (Section 6 explains what that means), this is the single most important line on your new policy to find.
What to do about it
Pull your declarations page and confirm three things, in this order:
- Find the deductible line and check whether it is a dollar amount or a percentage. If it says "1%" or "2%" rather than "$1,000," multiply it against your dwelling limit and write down the result.
- Look for a separate wind/hail or wildfire deductible. In Idaho this should usually be absent. If it is present, that is unusual for the state and you should ask your agent when it was added and why.
- Check whether any percentage runs off the dwelling limit or the total insured value. The base matters as much as the percentage.
Then spend the time you saved on Section 6, because in Idaho the deductible is not where the risk lives.
3. What a standard policy covers here — and the gaps
A homeowners policy is really several coverages bundled together:
- Coverage A — Dwelling. The structure itself.
- Coverage B — Other Structures. Detached garage, barn, shop, fence, shed. Usually about 10% of Coverage A automatically. On Idaho's larger rural and semi-rural parcels this default is frequently far too low — a detached shop or pole barn can easily exceed 10% of the house's value.
- 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. After a wildfire that displaces a whole subdivision at once, local rental supply disappears and this coverage gets tested hard.
Covered perils typically include fire, lightning, windstorm, hail, theft, vandalism, explosion, and sudden accidental water discharge from plumbing.
Wildfire is covered — that is the most important sentence in this section
A standard Idaho homeowners policy covers wildfire damage. Wildfire is fire, fire is a named covered peril on essentially every homeowners form, and there is no wildfire exclusion on a standard admitted-market Idaho policy.
This surprises people, because Idaho's wildfire problem is so visible in the market. But the problem is not that the policy excludes the fire. The problem is getting and keeping the policy — which is Section 6 — and, in the surplus-lines market, the risk that the policy you end up with is not a standard form at all. If you have been placed with a non-admitted carrier, read the peril list and the exclusions yourself rather than assuming a wildfire-country policy covers wildfire.
Flood is never covered — anywhere, by anyone's homeowners policy
This is universal across all fifty states. No homeowners policy covers flood. Flood coverage is a separate purchase through the National Flood Insurance Program (NFIP) or a private flood carrier.
In Idaho this gap has a specific and badly underappreciated shape: post-fire flooding and debris flow. A burn scar loses the vegetation and soil structure that absorb rainfall, and the ground above a burned slope can shed water for years afterward at rates it never did before. Debris flows off burn scars are one of the more destructive things that happen in the interior West, and they are a flood loss, not a fire loss — which means the homeowners policy that paid for your neighbor's fire damage may pay nothing for yours.
If you live below a recent burn scar, this is not theoretical and it deserves an NFIP quote regardless of what the flood map says. Being outside a mapped high-risk zone is a statement about a flood map, not about whether your house can flood.
Earthquake is excluded, and Idaho is seismically active
Standard homeowners policies exclude earthquake essentially everywhere, Idaho included. Idaho readers should note that this is not a formality here — central Idaho sits in an active seismic zone, and the 2020 Stanley earthquake was a magnitude 6.5 event. Earthquake coverage is available as a separate endorsement or policy. Ask for it by name; it will not appear on its own.
Other exclusions worth knowing
- Maintenance and wear. Insurance covers sudden accidental damage, not deterioration. A roof that failed gradually is a maintenance problem, not a claim.
- Mold, beyond limited sublimits.
- Ordinance or law — the extra cost of rebuilding to current code rather than as originally built. In wildfire-exposed areas this is increasingly expensive, because rebuilding may now require ignition-resistant materials, ember-resistant vents and Class A roofing that the original house did not have. Usually available as an endorsement. On an Idaho home in the wildland-urban interface, it is one of the highest-value endorsements you can buy.
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 correct. Dwelling coverage should equal the cost to rebuild your home from the foundation up at today's construction prices. Market value includes land, and land does not burn. Your mortgage balance is a financing number with no relationship to construction cost.
In Idaho this error usually runs in the direction of overinsuring. Idaho's median home price is about $503,400 — high for an interior state, driven by the Boise metro — and a substantial share of that is lot value. If you set Coverage A to your purchase price, you are likely paying premium on land that cannot be destroyed.
Working a real Idaho example
Rebuilding in Idaho runs roughly $215 per square foot — the midpoint of a published $170 to $260 band covering materials, labor, and general contractor overhead and profit, excluding land.
On a 2,000 square foot home:
- 2,000 x $215 = $430,000 to rebuild
Take the band seriously rather than the midpoint alone:
- At $170/sq ft: $340,000
- At $260/sq ft: $520,000
That is a $180,000 spread on the same house. It is a wide band, and it is honest to say why: this is a coarse published cost band rather than an Idaho-specific survey, and no Idaho building department or insurance regulator publishes a competing rebuild-cost figure to check it against. It should be read as a range, not a number.
Note also what this figure is not. It is construction cost — materials, labor and contractor overhead to rebuild finished living area after a loss. It is not market value, and it is not the price per square foot of a home sale. Treating one as the other is the single most common way a replacement-cost estimate goes wrong.
Now compare the two Idaho numbers side by side. Median home price $503,400. Rebuild cost for a 2,000 square foot home $430,000. For a typical Boise-area home the land is a meaningful fraction of the price, and the gap widens the closer you get to expensive lots. Get an actual replacement-cost estimate for your specific home from your carrier or an independent estimator rather than working from either number.
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 threshold and the insurer does not simply cap your payout at your limit — it reduces every partial claim proportionally.
Work it on the example. Full replacement cost $430,000, so the 80% threshold is $344,000. Suppose you carry the $300,000 reference limit instead, and a fire does $100,000 of damage. Your limit is three times the loss, so it feels perfectly safe. It is not:
- $300,000 carried / $344,000 required = 0.872
- 0.872 x $100,000 = $87,209
- Then subtract your $1,000 deductible
- Net payment: about $86,209 on a $100,000 loss
You are roughly $13,800 short on a claim well inside your policy limit, entirely because Coverage A was set too low. None of that 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. After a wildfire that destroys many homes at once, local contractor capacity and material prices spike hard. This endorsement exists precisely for that scenario, and Idaho is exactly the kind of state where it earns its cost.
- Ordinance or law coverage — as above, the cost of rebuilding to current code, which in the wildland-urban interface increasingly means ignition-resistant construction.
5. Roof age, and why it decides your premium and your payout
An honest limitation first. This site's Idaho data file does not record a statewide roof-settlement standard, because Idaho does not impose one. Whether your roof is settled at replacement cost or actual cash value is set by your policy form and your carrier's underwriting rules, not by Idaho 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.
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.
The gap grows every year the roof ages. Roofing typically depreciates on the order of 2.5% to 4% per year on these schedules, so a roof fifteen years into a twenty-year expected life can have the large majority of its value depreciated away — the insurer pays a fraction of replacement cost and you fund the rest. Your deductible then comes off the top of even that reduced amount.
What to look for on the declarations page: a "roof surfaces" endorsement, a windstorm-or-hail-loss-to-roof schedule, or any actual-cash-value language applied specifically to the roof. If you find one, that language overrides the general replacement-cost promise elsewhere in the policy for the roof only, and it is easy to miss.
In Idaho, roof condition is an availability question before it is a payout question
This is the Idaho-specific part, and it is more important here than the ACV question.
In a state that has gone from roughly 91 carriers to somewhere around 22 to 25 in two years, underwriting is not a pricing exercise — it is a gate. An aging roof does not move you from cheap to expensive. It moves you from insurable to declined, in a market with very few remaining places to go and no FAIR plan behind them.
There is a second Idaho-specific angle. Roof material matters here in a way it does not in most states, because of wildfire. Class A fire-rated roofing — the highest rating, covering most asphalt composition shingle, metal, tile and concrete products — is a core element of home hardening, since wind-driven embers landing on the roof are one of the primary ways houses ignite during a wildfire. If you are replacing a roof in Idaho anyway, the fire rating of what you install is a live underwriting variable, not just a construction preference.
The practical instruction: if your roof is nearing the end of its life and you live anywhere near the wildland-urban interface, replace it before your renewal rather than after your non-renewal. Once you have a non-renewal on your record, you are shopping a 22-carrier market from a weaker position. And ask your agent, item by item, which fire-resistant and impact-resistant materials carry credits — carriers do not always apply them automatically.
6. If no carrier will write you
This is the section that matters most in Idaho, and there is no comfortable way to write it.
Idaho has no FAIR plan. This was confirmed, not overlooked.
A FAIR plan (Fair Access to Insurance Requirements) is a state-organized insurer of last resort, typically an association of the carriers licensed in that state, that writes basic property coverage for applicants the voluntary market has declined. More than thirty states operate one.
Idaho does not. There is no FAIR plan, no state-backed insurer of last resort for homeowners, and no residual-market fallback of any kind. An Idaho homeowner who cannot find private coverage goes to surplus lines or goes without.
This is an affirmative finding, not an unchecked field. It is reported directly in Idaho market coverage and corroborated by 2026 wildfire-insurance reporting that specifically contrasts Idaho with the thirty-plus states that do operate a plan. No FAIR plan appears anywhere in Idaho Department of Insurance materials.
What "surplus lines" actually means, and the part nobody mentions
If the admitted market declines you, the remaining option is a surplus lines (also called non-admitted) carrier. These are legitimate, licensed insurers, and in wildfire country they are frequently the only market that will write a high-risk property at all. But they operate under different rules, and three differences matter:
- Their rates and forms are not filed with or approved by the Idaho Department of Insurance. An admitted carrier's rates go through regulatory review. A surplus lines carrier's do not. Pricing can move faster and further, and the policy form can be narrower than a standard homeowners form in ways you have to read for yourself.
- The policy may not be a standard form. Perils, exclusions, sublimits and settlement basis can all differ from what you are used to. This is where a separate wildfire deductible can appear.
- This is the one people do not know: surplus lines carriers are not covered by the state guaranty association. Every state has a guaranty fund that pays outstanding claims when an admitted insurer becomes insolvent. That protection does not extend to non-admitted carriers. If your surplus lines insurer fails, there is no state backstop for your claim.
None of that means surplus lines coverage is a bad decision — being insured by a non-admitted carrier is enormously better than being uninsured, and for many Idaho properties it is genuinely the only option. It means you should know what you are buying and check the carrier's financial strength rating before you sign, rather than assuming the protections you had with an admitted insurer travel with you.
What the state is actually doing about it
The Idaho Department of Insurance has not created a residual market. What it has done is measure the problem: two consecutive wildfire data calls, a 2025 request and Bulletin 26-02 in May 2026, assessing wildfire's impact on the property insurance market. The legislature has separately considered home-hardening bills (HB384 and H17) as an alternative route to preserving insurability — that is, keeping homes in the private market by making them more defensible rather than by building a public backstop behind them.
That is a coherent strategy, and it is also a slower one. As of this writing, no Idaho FAIR plan has been established. If you are reading this in a later year, that is the first fact on this page worth re-checking.
The honest framing
Idaho's home insurance market is inexpensive and structurally simple for the homeowners it still writes. For homeowners in wildfire-exposed areas, it is one of the harder markets in the country to stay in, and there is no public safety net underneath it. Those are both true at once, and which one describes you depends almost entirely on where your house sits relative to the wildland-urban interface.
If you are buying in the Idaho foothills or in a forested area, resolve insurance before you resolve financing. Get a bindable quote in writing on the specific address before your inspection contingency expires. A lender will require coverage, and discovering after closing that no admitted carrier will write the property is a far worse problem than discovering it during due diligence.
7. How to actually lower your premium in Idaho
Ranked roughly by how much they move the number — and, in this state, by how much they improve your odds of keeping the policy at all.
1. Harden the home against wildfire, and document it. This is the most Idaho-specific action on this list, and it is unusual in that it affects both your price and your availability. The measures that underwriters care about are specific: defensible space in the first five feet, thirty feet and hundred feet around the structure; Class A fire-rated roofing; ember-resistant vents; enclosed eaves and soffits; noncombustible siding; and removing anything flammable stored against the wall of the house. Take dated photographs. When your carrier reassesses your wildfire risk score, documentation of completed mitigation is what you have to argue with. This is also precisely what the legislature's home-hardening bills are aimed at.
2. Ask whether your community can qualify for recognized wildfire mitigation status. Community-level programs such as Firewise USA recognition are increasingly recognized by carriers, and some offer credits for properties inside a participating community. This is a neighborhood project rather than a solo one, but in a subdivision facing collective non-renewal pressure it is worth raising at an HOA meeting.
3. Get your Coverage A limit right — in Idaho this usually means lowering it. Because Idaho's median home price of $503,400 sits well above the $430,000 rebuild cost of a typical 2,000 square foot home, a meaningful number of Idaho homeowners are insured closer to market value than to construction cost and are simply overpaying. Get an actual replacement-cost estimate. This is the rare adjustment that can lower your premium and make your coverage more accurate. Just do not go below the 80% coinsurance threshold — Section 4 shows exactly what that costs on a partial claim.
4. Raise the all-perils deductible. Going from $1,000 to $2,500 lowers premium and is a clean trade in Idaho specifically, because there is no separate catastrophe deductible layered behind it — the $2,500 really is your maximum out-of-pocket per claim rather than a floor under a larger percentage. Do not do this if you would not comfortably write a $2,500 check tomorrow.
5. Do not take the percentage-deductible option unless you have done the arithmetic. Some Idaho carriers offer a percentage deductible as an alternative to the flat menu. On a $430,000 dwelling limit, a 1% option is $4,300 and a 2% is $8,600. That may still be a rational trade, but make it deliberately, in dollars, rather than accepting it as "the cheaper option" on a quote comparison.
6. Bundle home and auto. Multi-policy discounts remain among the largest routinely available anywhere. In a market that has gone from roughly 91 carriers to about 22, being a multi-policy customer also helps on the retention side — carriers are measurably less willing to non-renew a household that holds several of their policies.
7. Stop filing small claims. This is more consequential in Idaho than in most states. With 27,798 non-renewals in a single year, claims frequency is an active non-renewal trigger, not just a rating factor. Paying a $2,200 repair out of pocket is very often strictly better than a claim that nets you $1,200 after the deductible and puts a loss on your record in a market with almost nowhere else to go.
8. Shop before you are forced to, and shop early. The worst time to discover how few Idaho carriers remain is the week your non-renewal takes effect. Quote your policy annually while you still have coverage in force, and keep a note of which carriers were willing to look at your address. If you receive a non-renewal notice, start immediately — Idaho requires advance notice for a reason, and every day of that window is worth using.
9. Buy flood coverage anyway if you are below a burn scar. This raises your total spend rather than lowering it, and it belongs on the list because the cheapest possible premium is worthless if the damage came from water. Post-fire debris flow is a real Idaho exposure and it is a flood claim. In moderate-risk zones an NFIP policy is often far cheaper than people assume.
10. Re-shop annually, and compare the right four things. Line up the premium, the dwelling limit, the deductible structure (flat or percentage), and whether the carrier is admitted or surplus lines. A quote that beats yours on price while quietly moving you to a non-admitted carrier with a wildfire deductible is not a better quote. It is a different product.
What to do next
If you want these numbers applied to your actual house rather than a statewide average, the Idaho 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 Idaho construction costs — the first number to check, given how far Idaho's median home price sits above its rebuild cost. And the deductible calculator converts deductible options into real dollars against your specific dwelling limit, which is worth running if a carrier has offered you a percentage option instead of Idaho's usual flat one.
All three show every figure they use and where it came from.
This guide is general information about homeowners insurance in Idaho, based on publicly available figures current as of August 2026. It is not an insurance quote, a policy, coverage advice, or legal advice, and it does not reflect your individual property, wildfire risk rating, claims history, or carrier's specific policy language. Premiums, deductible options, availability, and underwriting rules vary substantially by carrier and by property, and Idaho's market has been changing quickly. For coverage specific to your home, speak with a licensed Idaho insurance agent; for regulatory questions or complaints, contact the Idaho Department of Insurance.
