Legal Question in Landlord & Tenant Law in California

Generally speaking the California Fair Debt Collections Practices Act known as the Rosethenal Act says a creditor can only contact you between the hours of 8:00 a.m. and 9:00 p.m. It might also cover some of their conduct depending on what degree. However if you are late then your landlord could serve you with a 3 day notice to pay or quit and start eviction proceedings against you. If you are continually late then they could also use that as a grounds for eviction.

My best advise is it is cheaper to pay your rent on time if you can and avoid the worry and potential costs of litigation.
