Stat. § 703.17 a condominium association must carry property insurance against fire and other hazards at not less than full replacement value of the insured property, plus a liability policy, written in the association's name as trustee for the unit owners, with premiums as common expenses. Non-condo HOAs have no equivalent § 703.17 mandate — their coverage comes from the CC&Rs, so the actual policy must be verified. The market context is genuinely stressful: NOAA counts 44 severe-storm (hail, wind, tornado) billion-dollar events affecting Wisconsin from 1980 through 2024, and reporting ties roughly 65 percent of 2024 Wisconsin homeowner claims to weather, with hail the leading warm-season cause. Chapter 703 does not mandate flood, wind/hail-specific, fidelity, or D&O coverage, so for a buyer the master policy is both a risk document and a financing document.
What § 703.17 actually requires of condominiums
For condominiums, Wis. Stat. § 703.17 requires the association to carry property insurance against fire and other hazards at not less than full replacement value of the insured property, plus a liability policy covering all claims commonly insured against. Coverage is written in the association's name as trustee for the unit owners in their declaration percentages, premiums are common expenses, and the association must insure all property other than unit owners' personal property — without prejudice to each owner's right to separately insure their own unit with an HO-6. Insurance proceeds are applied first to repair and restoration of damaged common elements; owners and mortgagees do not receive proceeds unless the association decides not to rebuild, a court orders partition, or there is a surplus. Coverage below the full-replacement floor is a statutory non-compliance flag.
HOAs: no statutory mandate, CC&Rs control
A non-condominium HOA or planned community has no § 703.17-style insurance mandate. A § 710.18 HOA's insurance obligations come primarily from the declaration and CC&Rs rather than from statute, so for an HOA-governed community the only way to know what is covered is to read the governing documents and the actual policy. This makes the condo-versus-HOA classification the first insurance question: it determines whether a statutory coverage floor even applies. No Wisconsin statute mandates fidelity (crime), directors-and-officers, or flood coverage for either type — though Fannie Mae and Freddie Mac effectively require fidelity-bond coverage and master-policy standards for warrantable condo financing, and owners in FEMA flood zones or on Lake Michigan or Lake Superior shoreline should carry NFIP or private flood coverage because master policies generally exclude flood.
Hail, wind, and percentage deductibles
Wisconsin sits in an active severe-storm corridor, and repeated hail damages roofs, siding, gutters, rooftop HVAC, and skylights on common elements. As nationally, Wisconsin master policies have seen premium increases and percentage-based wind/hail deductibles that can be far larger than a flat dollar deductible. Critically, bylaws frequently make the owner responsible for some or all of the master-policy deductible where damage originates in or affects a unit — a direct HO-6 loss-assessment gap. Wisconsin winters add ice dams and frozen-pipe and water-backup losses; insurers often pay resulting interior damage but not ice-dam removal, treated as maintenance, and may deny where poor upkeep contributed. Read the declarations page for any separate wind/hail deductible and confirm who pays it.
Deductibles, financing, and your own HO-6
As master deductibles rise, they collide with Fannie Mae and Freddie Mac's cap of generally about 5 percent of coverage; a master deductible above that limit can jeopardize conventional financing and resale value. Read the master declarations page as a financing document, then read your own HO-6 against it: because Wisconsin bylaws often push the master deductible onto the responsible owner, loss-assessment coverage on your HO-6 matters, and a building that just absorbed a hail-driven premium spike or a large uncovered loss is a stressed situation worth examining closely. Confirm whether the association plans any special assessment to fund a large deductible or an uncovered loss, and request the recent storm-claim history.

- Confirm whether bylaws pass the master deductible to owners (HO-6 loss-assessment gap)
- Check whether the deductible exceeds roughly 5 percent (GSE financing limit)
- Review the master-policy premium trend for sharp year-over-year increases
- Confirm flood coverage for shoreline (Lake Michigan/Superior) or floodplain buildings
- Review your own HO-6 loss-assessment limit against the master deductible
