What the risk data says about Novi
Novi carries a Basement Risk Index of 5 out of 100, ranking #114 of 116 metro Detroit communities, lower risk on our public-data index. Newer housing keeps its exposure toward the lower end of the metro range (5% of homes predate 1960), though low is not zero on the region's clay soil. That is the context for the license and diagnosis questions here; the full driver table, the map, and how Novi compares to its neighbors are on the Novi basement-risk breakdown →

Frequently asked questions
Why do basements flood in Novi?
Mostly housing age and soil. 5% of Novi homes were built before 1960, before sump pumps, exterior weeping tile, and backwater valves were standard, and the heavy clay soil across southeast Michigan holds water against those older foundations rather than draining.
Is a Basement Risk Index of 5 high for Novi?
A score of 5 is below the metro Detroit median of 37 (U.S. Census ACS 2020-2024, updated July 2026), ranking #114 of 116 communities. Lower is not zero on this region's clay soil.
