Market Overview

Water damage has passed fire as the leading cause of property loss in multifamily and commercial real estate, and it shows up as repeated six-figure events rather than one catastrophe. The piece covers leak detection sensors, automatic shutoffs, and the operational discipline around them. The part owners tend to miss is documentation: keeping logs of sensor installs, shutoff tests, and incident response gives underwriters something concrete to price against at renewal.
