Missouri requires at least 30 days' written notice of a non-renewal, with the insurer's actual reason, on an owner-occupied one- or two-family home. Earthquake, flood and sewer backup are each outside a standard homeowners policy and are added or bought separately. The Missouri FAIR Plan is the last resort: actual cash value, a low statutory limit, no liability and no earthquake. I look at standard and surplus lines markets before it.
What is in every underwriter's file on St. Louis
Four events, all documented by the National Weather Service office in St. Louis, explain most of the letters.
- May 16, 2025A tornado touched down in Clayton at about 2:41 pm and strengthened to EF3, with winds up to 152 mph, as it crossed the northern part of the City of St. Louis before entering Illinois near Venice. As of November 2026 the City's recovery office is still approving home repair applications in the tornado zone.
- April 22, 2011The Good Friday tornado, rated EF4 at Bridgeton, ran about 22 miles from Creve Coeur Lake through Maryland Heights, St. Ann, the airport, Berkeley and Ferguson. It damaged 2,700 structures and heavily damaged or destroyed 251 homes, with no deaths.
- April 10, 2001A single supercell laid a hail swath about 245 miles long down the Interstate 70 corridor into St. Louis. The Weather Service's review says nearly every home and business in northern St. Louis County is believed to have had hail damage.
- July 26, 2022The heaviest rainfall event since St. Louis records began in 1874, with as much as eleven inches from Hawk Point to St. Peters. Rising surface water and backed-up drains are not paid by a standard homeowners policy.
None of this makes a given house uninsurable. It does mean the roof's age, the claims on the address, and whether the 2025 repairs were finished and documented decide who will offer terms.
What Missouri law says about the notice
Sections 375.001 to 375.008 of the Revised Statutes of Missouri apply to owner-occupied homes of up to two families, which takes in a two-family flat when the owner lives in one unit. An insurer that will not renew must give at least 30 days' advance notice under section 375.004, state its actual reason in terms clear and specific enough to understand without further inquiry, and tell you the Missouri FAIR Plan may be available. After the first 60 days, a mid-term cancellation is limited by section 375.002 to non-payment, fraud or misrepresentation or a breach of policy terms, a crime that increases the hazard, or physical changes in the property that increase the hazard, on 30 days' notice (ten for non-payment).
Two more points help a declined homeowner. Section 375.007 says an insurer may not refuse to write solely because of where you live or because another insurer dropped you, though it may act where the hazard itself is greater. And the Department of Commerce and Insurance asks anyone whose homeowners premium doubles from one year to the next to call its consumer hotline. Its Division of Consumer Affairs takes complaints online and requires the company to respond.
Earthquake: the cover fewer St. Louis homes carry
A Missouri homeowners policy does not cover earthquake damage. It is an endorsement or a stand-alone policy, and the Department's annual report on the residential earthquake market says the high-risk area runs up the Mississippi from the Bootheel through the whole St. Louis metropolitan area. The U.S. Geological Survey records that the 1811 and 1812 New Madrid earthquakes caused structural damage as far away as St. Louis. The Department cites a USGS estimate of a 25 to 40 percent chance of a magnitude 6 or larger earthquake in the zone within 50 years.
- Who still has itIn the Department's 2025 report, 35.7% of residences in St. Louis County carried earthquake coverage, down from 56.0% in 2016. In the City of St. Louis it was 16.6%, down from 29.0%. St. Charles County stood at 41.5% and Jefferson County at 35.2%.
- DeductiblesA percentage of the dwelling limit, with a separate one for contents. The Department calls 10 to 20 percent common and reports that some insurers sell only 20 or 25 percent.
- BrickThe Department notes that earthquake premiums run lower for wood-frame homes and that some insurers will not offer earthquake cover on masonry homes at all. For fire, brick is the cheaper material to insure. A St. Louis brick house gets both answers.
Fire and water damage from gas and water lines broken in an earthquake is, in the Department's words, generally covered by the standard policy. Shaking damage is not.
Sewer backup and flood are two more policies
The Metropolitan St. Louis Sewer District says the City of St. Louis is served by a combined system, where wastewater and stormwater share a pipe, while most of St. Louis County has separate sewers. It also says the lateral line from the house to the public sewer is private property and the owner's to maintain, that most backups come from the private plumbing, and that they are most likely in heavy rain. The District has a limited assistance program for building backups in certain cases. Water that comes up through a basement drain is covered only if the policy carries the sewer and drain backup endorsement, and flood from rising surface water takes a separate flood policy from the National Flood Insurance Program or a private insurer.
The Missouri FAIR Plan, and where it falls short here
The Missouri FAIR Plan, based in St. Louis, will write a one- to four-family dwelling, owner- or tenant-occupied, and will consider a vacant one that is maintained with working utilities and current taxes. It is still a narrow policy:
- Actual cash value only. The Plan tells applicants it does not offer replacement cost and to insure to market value. On an older house, depreciation on the roof comes out of the claim.
- A statutory limit of two hundred thousand dollars on building and contents together for a dwelling.
- No liability, earthquake, flood or sewer and sump backup. Wind and hail are covered perils, with fire, lightning, explosion, smoke, vehicles and vandalism.
- Inspection. Every new property is inspected. Deficiencies bring a surcharge or a 30-day cancellation notice, and fuse boxes, deteriorated chimneys and having no central heat are on the Plan's list of problems.
Application goes through a Missouri-licensed agent, after a real effort in the standard market. The Department names surplus lines as the other route, and for a home worth more than the FAIR Plan limit that is usually where I end up when standard insurers pass.
What I need to quote
The notice, the declarations page, the address, year built and construction (solid brick, brick veneer or frame), roof type and the year it was replaced, the age of the wiring, plumbing and heating, whether there is a basement with a sump or a backflow valve, any claims in the last five years including 2025 tornado or hail repairs, and the date coverage must start. Say whether you want earthquake quoted, and at what deductible.
Common questions
Who insures a home in St. Louis after a non-renewal?
Other standard insurers first, then the surplus lines market, and the Missouri FAIR Plan as a last resort. The FAIR Plan pays actual cash value up to a low statutory limit and carries no liability, so it is rarely the whole answer.
Does homeowners insurance cover earthquake damage in St. Louis?
No. The Missouri Department of Commerce and Insurance says earthquake must be bought as an endorsement or a separate policy, usually with a deductible of 10 to 20 percent of the dwelling limit.
Can I get earthquake insurance on a brick house in St. Louis?
Sometimes. The Department notes that some insurers will not offer earthquake cover on masonry homes and that wood-frame homes are priced lower, so the answer depends on the insurer and on how the house is built.
Why was my St. Louis home insurance non-renewed after the 2025 tornado?
Missouri lets an insurer decline to renew on the anniversary date with 30 days' written notice and its actual, specific reason. Read the reason on the notice: roof condition, claims and unfinished repairs can often be answered with documents.
Is a sewer backup in my basement covered in St. Louis?
Only if your policy has the sewer and drain backup endorsement. The sewer district treats the lateral line as the owner's responsibility, and the Missouri FAIR Plan excludes backup entirely.
Does my homeowners policy cover flash flooding like July 2022?
Generally not. Flood is a separate policy from the National Flood Insurance Program or a private flood insurer, and NFIP coverage normally starts 30 days after you buy it.
How much notice must a Missouri insurer give before cancelling a homeowners policy?
Thirty days for a non-renewal or a mid-term cancellation, and ten days when the reason is non-payment, under RSMo 375.003 and 375.004.
General information about home insurance in the St. Louis area as of November 2026, not legal advice. Statute summaries are from the Missouri Revisor's site; earthquake figures are from the Department of Commerce and Insurance's 2025 residential earthquake report; FAIR Plan terms are from the Plan's own site and can change, as can insurer appetite. Read your own notice and policy, and confirm deadlines with the Department. Coverage depends on underwriting and the terms, conditions and exclusions of the policy actually issued.
