The one-month deposit cap
California limits how much a landlord can charge for a security deposit. Under current law, most landlords may collect no more than one month's rent as a security deposit, regardless of whether the unit is furnished.
There is a limited exception for certain small landlords — for example, some individual owners of a small number of units — who may be allowed to collect up to two months' rent. But for most rentals, the one-month cap applies. This is a change from older rules that allowed larger deposits, so it is worth knowing the current limit.
This cap is separate from your first month's rent, which a landlord can also require up front. And whatever amount you pay as a deposit remains refundable except for lawful deductions.
Because deposit rules have changed and there are exceptions, the exact limit for your situation can depend on your landlord and unit. If you believe you were charged more than the law allows for a security deposit, a free, confidential review can help you understand whether the amount was proper and what you can do.
