I know the CA standard is 21 days, but if I am reading the information right, 21 days is rather excessive and there would need to be a good reason for the delay. My landlord has not communicated with me in over 5 days and it has been 7 since move out. The last she had said was she was going to "wait" to see if any stains come back up in the carpet after it had been cleaned. I had a walkthru that I requested prior to move out and got a "normal wear and tear" rating from the property manager. After I moved she had a contractor come in and re-evaluate the house. This was after everything on the previous walk thru had been done. Including prof cleaned carpets.
