Missouri guide
Missouri insurance risk
Insurance is Missouri's defining condo risk. MUCA § 448.3-113 requires the association to maintain property insurance on the common elements at no less than 80% of actual cash value after deductibles — not full replacement cost — plus liability coverage, "to the extent reasonably available." There is no statutory fidelity, flood, wind, hail, or earthquake mandate.

Against that thin floor sits one of the nation's most severe weather profiles: Tornado Alley, top-tier hail, river and flash flooding, and the New Madrid Seismic Zone. After the May 16, 2025 EF3 tornado in north St. Louis and statewide 2025 losses approaching $2 billion, the Missouri Department of Commerce & Insurance issued bulletins (Oct. 16 and Nov. 4, 2025) ordering insurers to halt cancellations and non-renewals of storm-damaged condo master policies. For a Missouri buyer, the master policy is both a risk document and a financing document.

The 80%-ACV statutory floor
MUCA § 448.3-113 sets the property-insurance floor at 80% of actual cash value, not replacement cost. The association's policy is primary over any overlapping owner coverage, the insurer waives subrogation against owners, and 30-day notice of cancellation or non-renewal must go to the association, owners, and mortgagees. The ACV floor is a meaningful gap: after a total loss, the difference between actual cash value and replacement cost can become a large special assessment. Confirm the valuation basis on the master declarations page.
The 2025 master-policy non-renewal crisis
Missouri's largest residential-property loss category is wind and hail, and 2025 brought a catastrophe shock — the north St. Louis EF3 tornado (about $1.6 billion in damage) and statewide insured losses near $2 billion. Condo associations across the state received master-policy non-renewal and cancellation notices, prompting the DCI's October and November 2025 bulletins directing insurers to avoid adverse underwriting actions on storm-damaged condo master policies. Confirm the building's master policy is in force and request the loss and claim history.
Percentage wind/hail deductibles and flood gaps
Missouri policies have shifted widely from flat-dollar to percentage-based wind/hail deductibles, pushing far more post-storm cost onto associations and, via deductible-allocation provisions, onto owners. Flood is excluded from standard property and HO-6 policies and insured through NFIP or private flood; roughly 200 Missouri communities have opted out of NFIP participation. Read the deductible structure and confirm flood-zone status and any flood coverage for riverfront or low-lying buildings.
New Madrid earthquake: the coverage that usually isn't there
Earthquake is a separate endorsement and is rarely purchased in southeast Missouri. New Madrid earthquake-insurance cost has risen more than 800% since 2000, and the insured share has fallen sharply — a large uninsured catastrophe gap. Missouri has no statewide seismic code, and local detailing is uneven. For buildings in or near the Bootheel and parts of greater St. Louis, confirm whether the association or owners carry an earthquake endorsement and weigh loss-assessment coverage on your own HO-6.

The math
$20,000,000 building
× 5% wind deductible
= $1,000,000
sits between the storm damage and the first dollar the insurer pays — and can be passed to owners as a loss assessment.
Bare-walls vs. all-in
A bare-walls master policy stops at the unfinished walls — your HO-6 has to cover drywall, flooring, cabinets, and fixtures. An all-in policy reaches the original fixtures. Which one your building carries decides how much HO-6 coverage you actually need.
Loss-assessment coverage on your HO-6 is the buffer for the deductible above — and it's frequently set too low.
