Using repair and deduct for hot water
California's "repair and deduct" law can let a tenant fix a serious problem like no hot water and subtract the cost from rent in limited situations — but it has strict rules and limits, so it is easy to get wrong. Get advice before using it.
Repair and deduct generally applies only to conditions that make a home unlivable, requires giving the landlord notice and a reasonable time to fix the problem first, and caps how much you can deduct and how often you can use it. Acting too soon, deducting too much, or misjudging the situation can lead to an eviction case.
Because the rules are technical, it is worth talking to an attorney before you hire your own plumber and take money off the rent. Before you repair and deduct over hot water, a free review can help you do it safely.
