Minnesota is not a coastal state, but its condo and townhome owners face a coastal-grade insurance and assessment crisis. The cause is hail. Minnesota has repeatedly led the nation in hail losses, and 2022 was its costliest storm year on record. As those losses mounted, the insurance market did what stressed markets do: it raised premiums — Minnesota posted among the steepest home-insurance rate increases in the country in 2025 — and it restructured deductibles in a way that quietly shifted enormous risk onto individual owners.

For a condo or townhome buyer, the result is one of the most important numbers in the entire document set: the master policy's wind/hail deductible. Read it wrong, or skip it, and you can inherit a five-figure special assessment within your first year of ownership.

How the percentage-deductible trap works

For years, association master policies carried flat deductibles — a hailstorm might mean a $10,000 deductible the association absorbed and the insurer paid the rest. That has changed. Many Minnesota master policies now apply a percentage-of-value wind/hail deductible of 1% to 5% or more. On a large building, 5% of insured value can translate to a deductible of $1 million or more — figures of $1M to $2.6M have been reported.

Here is the trap. Hail damage is often partial: a torn-up section of roof, dented siding, ruined gutters. The repair might cost several hundred thousand dollars — a real number, but smaller than the deductible. When a loss falls below the deductible, the insurer pays nothing. The association still has to fix the roof. So it bills the owners, through a special assessment.

That is why recent Minnesota owners have received special assessment bills of $16,000 to $23,000 each. In one widely reported case, a homeowner was billed $16,116 because roughly $1.7M of hail damage fell below a $2.6M deductible. In a Big Lake townhome community, owners were billed $22,760 apiece for roofs, siding, and gutters under a roughly $1.2M deductible. These are not exotic edge cases — they are the predictable output of a percentage deductible meeting a partial hail loss.

Roof age, ACV, and non-renewal

The deductible is the headline, but two related shifts deepen the risk:

• Actual cash value (ACV) roofs. Carriers increasingly insure older roofs on a depreciated basis rather than replacement cost — sometimes for roofs as young as 10 to 15 years. If the roof is on ACV and it is destroyed, the payout is reduced by depreciation, widening the gap owners must cover.
• Age-based non-renewal. Some carriers non-renew associations, or demand roof replacement, based on roof age and storm history. A non-renewal forces the association into surplus-lines coverage at higher cost and often a worse deductible.

When you read a Minnesota master policy, you are really reading three things together: the wind/hail deductible, the roof valuation basis, and the roof age. They compound.

What MCIOA does and does not do here

The Minnesota Common Interest Ownership Act (Minn. Stat. §515B.3-113) requires the association to carry property insurance on the common elements at full insurable replacement cost less deductibles, plus liability coverage. That sets a floor — but it cannot control the deductible structure the market imposes, and it does not require the association to fund reserves that could otherwise absorb a below-deductible loss.

MCIOA does give buyers two tools that matter here:

• The §515B.4-107 resale disclosure certificate discloses insurance coverage and any extraordinary expenditures approved for the current and next two fiscal years — a forward-looking warning of a planned assessment.
• The 10-day cancellation right lets you cancel the purchase agreement within 10 days after receiving the association documents (unless they were delivered more than 10 days before signing). That window is exactly when you should be quantifying your hail exposure.

What to request and read

• The master insurance declarations page — confirm the wind/hail deductible as a dollar figure, not just a percentage
• The roof valuation basis (replacement cost vs actual cash value) and the roof age
• Whether coverage is placed in surplus lines, which signals the standard market was unavailable
• The special-assessment history — repeated hail-driven specials indicate a structural mismatch between the deductible and the reserves
• For townhome HOAs, whether a §515B.3-115(e) plan assesses fewer than all units, which can concentrate one building's roof bill on its owners
• Your own HO-6 loss-assessment limit, which pays your share when the association passes a deductible to owners

When you read the deductible against the roof age and the reserve balance, you can estimate your realistic special-assessment exposure before your 10-day cancellation window closes. A high percentage deductible is not automatically a reason to walk away — but it is a number you want quantified, and matched against your own loss-assessment coverage, before you commit.
