When a plumbing problem breaks the law
A serious plumbing problem can be a habitability violation in California when the landlord fails to fix it. State law requires rentals to have plumbing kept in good working order, including hot and cold running water.
California's habitability standard (Civil Code Section 1941.1) lists working plumbing, gas facilities, and hot and cold running water among the basics a livable home must have. A minor issue fixed promptly is just a routine repair. But a significant plumbing failure the landlord ignores — no water, no hot water, a major leak, or a backed-up drain — can breach the implied warranty of habitability, the promise that your home will be fit to live in.
How serious the problem is, how long it lasts, and whether the landlord responded after being notified usually decide the question. If a plumbing problem is going unrepaired and your landlord will not act, a free, confidential review can explain your options.
