When water intrusion becomes a habitability issue
Water intrusion means unwanted water getting into a home — through the roof, walls, windows, foundation, or plumbing. When it is ongoing and the landlord fails to stop it, it can be a habitability problem.
Water intrusion covers everything from a leaking roof and seeping walls to windows that let rain in and moisture rising through a foundation. Beyond the immediate mess, it damages the structure over time and creates the damp conditions that mold needs to grow.
Because keeping the building weathertight and dry is part of the landlord's duty, unaddressed water intrusion can breach the implied warranty of habitability — the promise that your home will be fit to live in. The key question is usually whether the landlord acted after being told. If water keeps finding its way into your home and your landlord will not stop it, a free review can explain your options.
