Idaho is one of the cheapest states in the country for home insurance, but the average swings by hundreds of dollars depending on how much dwelling coverage a study prices. Insurify's Idaho study, updated August 10, 2026, puts the state average at $1,740 a year for $300,000 in dwelling coverage with a $1,000 deductible, against a national average of $2,844 — roughly $1,100 less at the same coverage level.

ValuePenguin, updated August 11, 2026, prices $350,000 of dwelling coverage and gets $1,759 a year in Idaho, 27% less than its $2,395 national average. NerdWallet, updated March 17, 2026, prices $400,000 and gets $2,195 statewide, 12% less than the national average of $2,490.

NerdWallet is also the only 2026 study publishing a Boise city figure with a stated methodology: $2,170 a year, or $181 a month. Boise runs slightly below the Idaho statewide average in that same study.

The rows are not interchangeable. All four rate studies cited on this page publish methodology and three run on Quadrant Information Services data, but all four are lead-generating comparison sites.

NOAA's Storm Events Database recorded 34 thunderstorm wind events in Ada County between January 1, 2015 and December 31, 2025, against 7 hail events over the same eleven years — a ratio of 4.9x.

NOAA logged 5 High Wind events in the county over that window as well. The strongest was a 67-knot measured gust on June 5, 2020, roughly 77 mph, above the National Weather Service hurricane-force threshold of 64 knots. Those are zone-level readings for the Upper Treasure Valley, not measurements at any one address.

The counts describe outbreaks rather than 34 separate windy days: eight of the 34 events fall on May 21, 2023 and six more on June 7, 2023. Hail showed up on only five distinct days in eleven years, the largest stone 1.50 inches. That is why the percentage wind and hail deductibles standard in Plains and Gulf states are largely not an Idaho issue.

Wildfire is the tail risk that shapes Idaho underwriting. Idaho has 100,233 housing units at risk for extreme wildfires, seventh among states, per CoreLogic's 2023 risk data published by the Insurance Information Institute. In 2022 — the most recent year the institute publishes at state level — Idaho recorded 1,088 wildfires burning 436,733 acres, fifth nationally by acreage, per National Interagency Fire Center data. That center is headquartered in Boise.

Locally, the City of Boise's Wildland-Urban Interface Overlay requires Class 1 Ignition-Resistant Construction in IR1 areas and Class 2 in IR2 areas, covering roofing, siding, eaves, defensible space and firewood storage. It applies to new structures and to renovations that increase gross floor area by more than 49 percent.

The city describes IR1 as generally foothills fire hazard areas and IR2 as generally valley and desert areas, so check the city's overlay map instead of assuming. Homes inside the overlay are underwritten differently, which is the practical reason an address-level quote beats a state average.

Insurify's Idaho table, as of August 10, 2026, prices 12 carriers at $300,000 dwelling coverage with a $1,000 deductible, for a home built in 1980 with no prior claims and good credit. The five cheapest:

The two cheapest are regional Northwest carriers most Boise homeowners have never heard of. The sixth name, Travelers at $1,471, is a $161 step up, so the cheap five is a real cluster rather than an editorial cutoff. Familiar brands sit higher in the same table: State Farm $1,545, Allstate $1,730, Farmers $1,990, Nationwide $2,805.

ValuePenguin's separate study, updated August 11, 2026, names State Farm cheapest for most homes at $1,054 a year, or $88 a month — but at $350,000 dwelling coverage and a different rating profile. The two studies disagree on State Farm because the benchmarks differ, which is why the tables must not be merged. Insurify refreshes its rates monthly, so treat the ordering as an August 2026 snapshot.

Every 2026 Idaho rate study cited here prices a $1,000 deductible, the standard Idaho baseline. The Idaho Department of Insurance says Typically, a higher deductible amount will result in a lower premium. Triple-I's consumer guidance says raising a deductible to $1,000 may save as much as 25 percent — an illustrative ceiling, not an expected saving.

Claims history is the harshest documented lever in Idaho. Insure.com's Quadrant-sourced data, updated August 11, 2026, shows the Idaho average rising from $2,148 a year with no claims to $2,885 after one fire claim, a 34% increase, priced at $300,000 dwelling, $100,000 liability and a $1,000 deductible. After two fire claims the Idaho average is $3,362, which the study reports as a 55% increase.

Roof age matters too, though the numbers are national. Insurance marketplace Matic's 2026 mid-year report, drawn from its own book of quoted and insured properties rather than a market-wide sample, puts the gap between a 1-5 year old roof and an 11-15 year old roof at $189 in the first half of 2026, a 10.7% difference, up from $65 in 2021, $96 in 2024 and $138 in 2025.

The Idaho Department of Insurance does not approve homeowners policy rates. It has authority only to disapprove rates it finds excessive, inadequate, or unfairly discriminatory. No agency caps what a carrier charges here, so shopping is the lever a homeowner controls.

The department also says In Idaho, there are few limitations on cancelling or non-renewing property insurance. An insurer must send written notice with the effective date and the reasons, and the required notice period depends on the reason; the department publishes no single day count.

• Quote every carrier at the same dwelling amount and the same $1,000 deductible.
• Include regional carriers, not just national brands.
• Ask which discounts apply — Triple-I cites 5 to 15 percent for buying two or more policies from one company, and at least 5 percent for a smoke detector, burglar alarm or dead-bolt locks.
• Have roof age and claims history ready before an underwriter pulls them.
