Under California law, a landlord must return the renter's security deposit, with an itemized statement of deductions, within 21 days after the renter has surrendered the rental property to the landlord (that is, returned the keys and vacated the property).
租客的合同是到8/1. 她6/15就搬出去了，但是钱还继续付到7/31. 我是应该在7/15 之前把security deposit 退给她，还是等到lease 到期（7/31）再退给她？
谢谢！
Use some common sense.
When did she return the key, when are you renting the house out again ...
