What “reasonable time” means
California landlords generally must fix serious habitability problems within a reasonable time after they are notified. For many repairs, around 30 days is treated as a common reference point — but a truly urgent problem cannot wait that long.
What counts as "reasonable" depends on how serious and dangerous the condition is. A total loss of heat, water, electricity, or a sewage backup should be handled quickly, sometimes within a day or two, because those conditions directly threaten health and safety. A less urgent repair may fairly take a bit more time. In short, the more dangerous the problem, the faster the landlord is expected to act.
Giving written notice — and keeping a copy — helps establish exactly when the clock started. Note the date you reported the problem and any follow-ups. If a landlord lets a serious condition drag on well past a reasonable time, you may have several options. If your landlord is dragging their feet on an important repair, a free review can help you decide what to do next.
