The 2021 Metro Detroit floods produced over $1 billion in losses — much of it uninsured commercial damage. Compare NFIP and private commercial flood quotes from a Michigan-licensed agent.
Get Your Free Detroit QuoteDetroit's combined sewer system, Detroit River shoreline, and aging stormwater infrastructure produce some of the most concentrated commercial flood exposure in the Midwest. The June 2021 Metro Detroit floods inundated thousands of basements and ground-floor commercial properties across Detroit, Dearborn, Grosse Pointe, and downriver communities, with total losses exceeding one billion dollars. Standard commercial property policies covered none of it — flood is excluded across the board.
Detroit commercial properties in FEMA-designated Special Flood Hazard Areas — including parts of the riverfront, the lower east side, and several downriver communities — carry lender-required flood insurance. Many properties outside the SFHA still face exposure. The 2021 floods affected properties miles from any mapped flood zone because the water came from sewer backup and surface runoff, not from the river. Detroit's 100-year-old combined-sewer infrastructure means heavy rain events will continue to produce commercial losses across the metro area.
We're a Michigan-licensed agency that writes commercial flood for Detroit metro businesses across every neighborhood. We shop both NFIP and private commercial flood markets and present a side-by-side comparison — including the higher limits and business interruption coverage that private flood can provide and NFIP cannot.
Detroit River shoreline commercial properties sit in or near the Special Flood Hazard Area. Federally regulated lenders mandate flood coverage on these properties.
Detroit's combined sanitary/storm sewers back up during heavy rain. The 2021 event produced commercial losses across neighborhoods well outside any mapped flood zone.
Lincoln Park, Wyandotte, Trenton, and the downriver industrial corridor carry meaningful flood exposure from the river and from Rouge River tributaries.
Detroit commercial property owners have two paths to flood coverage. The NFIP commercial flood program offers up to $500,000 in building and $500,000 in contents coverage for almost any Detroit commercial property. The private commercial flood market often offers higher limits, business interruption coverage, and competitive pricing — particularly for higher-value Detroit properties or those with strong elevation.
We shop both paths and present them side-by-side. Use our flood zone lookup tool to see whether your Detroit property sits in a Special Flood Hazard Area before you request a quote.

Detroit commercial flood premiums vary widely by location. Low-risk properties may see NFIP quotes from $600 to $1,800 a year. Riverfront, downriver SFHA, or basement-heavy properties frequently run $2,500 to $6,000+. Private flood is competitive on many Detroit commercial properties.
Federally regulated lenders are required to mandate flood coverage on commercial properties in Detroit's Special Flood Hazard Areas. Outside SFHAs, flood is optional — but the 2021 event made clear that coverage is worth considering even outside mapped zones.
No. Michigan commercial property policies exclude flood damage. Sewer backup is sometimes covered by a separate endorsement, but it's a different coverage from flood, and the 2021 Detroit losses straddled both — making a paired flood + sewer backup approach important for Detroit commercial property.
Yes — most Detroit commercial properties qualify for private flood. Private markets typically offer higher limits than NFIP's $500K cap and can include business interruption coverage that NFIP doesn't provide. We shop both.
Our Michigan commercial flood insurance page covers statewide flood-risk patterns, pricing ranges, and the Michigan-specific reasons businesses need flood coverage.
We also write commercial flood insurance in other Michigan cities including Grand Rapids, plus statewide.
