Section 8 tenant's lease is up, can I not renew the lease?

[Jade Wong]

My section 8 tenant is a c-tenant, always pays rent late or failure to pay for a couple of months. His lease expired last November and I haven't renewed it because I've been thinking if I should. Here're my questions:

1. Does this lease automatically become month-to-month? 

2. Can I give him a 30 day notice to ask him to move out?

3. Do I need to contact HOA to terminate his lease?

4. He sent us a repair request but doesn't let us go into the house when we tried to schedule a time. He said he would ask for an emergency inspection from HOA first. Is this right?

Thanks for your answers in advance!
