Michigan's Essential Insurance Act lists the only reasons an insurer may decline or drop an eligible homeowner, and requires 30 days' written notice with each specific reason. The age of the house and the neighborhood are not on the list. If no standard insurer will write the home, Michigan Basic is the fallback, and it covers neither sewer backup nor flood.
What Michigan law gives you when the letter arrives
Under MCL 500.2123, a termination of home insurance is not effective unless the insurer mails or delivers written notice at least 30 days before the date, stating each specific reason. A notice sent in the first 55 days of a new policy can take effect in 20 days, and nonpayment follows the policy's own terms. The reason also has to conform to the insurer's own underwriting rules.
Those rules are fenced in by MCL 500.2117. An insurer may refuse to insure, or to keep insuring, an eligible person only under underwriting rules based on the grounds the statute lists:
- Physical conditionRules must be objective, tied to the perils insured, and based on a housing or safety code or a similar standard, without regard to the age of the structure. A certificate of compliance from the local government creates a rebuttable presumption that the home meets them.
- ClaimsFor non-renewal, the statute speaks of three paid claims in the preceding three years above dollar totals it sets and adjusts for inflation, with a lower total when weather claims are left out. Liability claims are excluded.
- VacancyA dwelling unoccupied for more than 60 days, where there is evidence of an intent to leave it vacant.
- Next doorAn adjacent physical hazard, but for a non-renewal only if the hazard has changed since the policy was first issued. Residential property and traffic patterns do not count.
The state's consumer sheet on eligibility says it plainly: you cannot be denied solely because of the age of your house, its location or the type of neighborhood. If an insurer declines you, MCL 500.2122 requires it to tell you each specific reason, in writing if you applied in writing.
Roof photos, and how to push back
Many notices now start with an aerial photograph. In Bulletin 2025-12-INS, issued June 6, 2025, the Department of Insurance and Financial Services told home insurers that cosmetic roof issues such as discoloration or streaking are not valid grounds for cancellation or non-renewal, and that unclear or outdated images can be an improper basis for action. The bulletin says an insurer relying on aerial imagery should tell the homeowner so, provide copies of the images, and let the homeowner challenge them or correct confirmed roof damage first.
MCL 500.2113 gives you a route. If you believe you were improperly denied home insurance or charged an incorrect premium, you are entitled to a private, informal conference with a manager at the insurer. If the insurer does not give you a conference and a proposed resolution within 30 days, or you disagree with the result, the Department decides the matter. Its consumer line is 877-999-6442. I ask for the images and the written reasons on day one, because the next underwriter will ask what was wrong and whether it was fixed.
Michigan Basic, in plain words
The Michigan Basic Property Insurance Association is the state's FAIR plan, organized under a 1968 act, with its member insurers assessed for any operating deficit. Its stated mission is basic property insurance on qualified property when coverage cannot be obtained through the standard market. The Department's consumer sheet describes qualified property as a residence that meets building code standards and is not used for farm, business or illegal purposes. You cannot apply directly; a licensed agent submits the application.
- FormsHomeowners forms the Department calls equivalent to HO-2 and HO-3, offered on a replacement cost or a repair cost basis, plus a basic dwelling fire form at actual cash value.
- Not coveredThe association's own comparison chart shows no coverage for flood or surface water, backup of sewers or drains, or earthquake on any of its forms.
- Water add-onA limited water damage endorsement is sold for rain, ice, snow or sleet. The Department warns that it may still exclude flood, sewer or drain backup and ground water seepage.
- InspectionAn inspection is ordered once the policy is effective, and poor exterior conditions can lead to an interior one. If you are told the property does not qualify, you are entitled to a written explanation and what would make it qualify.
- Do Not RenewThe association says a policy flagged this way will not renew unless you respond 45 days before expiration with proof the listed conditions were corrected.
Each location needs its own policy. I treat Michigan Basic as a bridge: fix what the inspection found, then go back to the standard market, where the Act obliges insurers to consider you.
Basements: sewer backup and flood are two different policies
The loss I plan for in Detroit is water in the basement. On June 25 and 26, 2021, the National Weather Service recorded three to six inches of rain across most of the metro area in 24 hours, with up to eight inches reported in Grosse Pointe, and flooded basements and freeway closures across Wayne and Washtenaw counties. A federal major disaster declaration followed for Wayne County, and another for the storms of August 24 to 26, 2023, when the Lower River Rouge saw major flooding.
The Department's guidance after those storms is consistent: flood is not covered by a standard homeowners policy, and water and sewer backup are not automatically covered either. Backup cover is an endorsement you ask for, with its own limit. Flood is a separate policy, from the National Flood Insurance Program or a private insurer, and the Department notes that federal flood coverage typically takes 30 days to go into effect. When you report water damage, describe what happened without labelling it a flood yourself; the cause decides which coverage answers.
If the water came up through a public sewer, Michigan's governmental immunity law, MCL 691.1419, requires written notice of the claim to the agency within 45 days of discovering the damage. That deadline runs separately from anything owed under your own policy.
Wind, hail and tornadoes
Wind is the frequent claim. On July 26, 2023, a line of storms brought gusts of 60 to 70 miles per hour, with the Detroit and Grosse Pointe areas among the hardest hit. On September 3, 2026, an EF-2 tornado crossed the east side of Detroit from near East Forest Avenue to Belle Isle, the first confirmed tornado inside the city since July 2, 1997; the same two days produced hail over two inches in diameter along the I-69 corridor. After a season like that, underwriters look hard at roof age and at trees over the house. Read the wind and hail deductible on every quote, since some are written as a percentage of the dwelling limit instead of a flat amount.
What I need to quote
The address, year built and square footage, roof type and year, updates to wiring, plumbing and heating, whether the basement is finished and has a backwater valve or sump pump, your current declarations page, the non-renewal notice with its stated reasons, and the date coverage must start. If the city issued a certificate of compliance for the house, send that too.
Common questions
Who insures a home in Detroit after a non-renewal?
Standard insurers first, since Michigan law limits the reasons any of them may turn down an eligible homeowner. Then surplus lines insurers, and last the Michigan Basic Property Insurance Association through a licensed agent.
Can an insurer refuse my Detroit home because it is old or because of the neighborhood?
Not for that reason alone. Under the Essential Insurance Act, rules about physical condition must be based on housing or safety codes without regard to the age of the structure, and the state's consumer sheet says location and neighborhood type cannot be the sole reason.
How much notice does a Michigan insurer have to give before non-renewing a home policy?
At least 30 days' written notice stating each specific reason, under MCL 500.2123. A notice sent within the first 55 days of a new policy can take effect after 20 days.
Does Michigan Basic cover sewer backup or a flooded basement?
No. The association's coverage chart lists no cover for flood, surface water or backup of sewers or drains on any form, and the state warns its optional water damage endorsement may still exclude them.
Why did my home insurance go up in Detroit?
Repeated wind and water losses are the usual drivers: federal disaster declarations for Wayne County storms in 2014, 2021 and 2023, and a tornado in the city in September 2026. If you think the premium is wrong for your home, Michigan law gives you a conference with the insurer and then a review by the state.
Do I need flood insurance in Detroit if I am not in a flood zone?
A homeowners policy does not pay for flood in any zone, and the June 2021 rain flooded basements across Wayne County. A flood policy is separate, and federal coverage typically takes 30 days to start, so it has to be bought before the forecast.
General information about home insurance in Detroit and southeast Michigan as of November 2026, not legal advice. Statute summaries are from the Michigan Legislature's site; claim thresholds in MCL 500.2117 are adjusted for inflation, and insurer appetite and Michigan Basic's rules change. Read your own notice and policy, and confirm deadlines with the Michigan Department of Insurance and Financial Services. Coverage depends on underwriting and the terms, conditions and exclusions of the policy actually issued.
