When a tenant is at least 5 days late with rent, you have to notify your tenant by certified mail of their lateness and tell them the total amount of rent due. Then you have to serve the tenant with a 14 day rent demand, which lets the tenant know they have 14 days to pay all the back rent owed, or move out. If your tenant pays the rent in full within the 14 day period, then you can no longer evict them for nonpayment of rent, as the rent has been paid.
If they refuse to pay you in full or move out by the expiration of the 14 days, the landlord can then initiate an eviction proceeding for nonpayment of rent in court.
