Ask a landlord-tenant lawyer and get answers ASAP
I'm Lucy, and I'd be happy to answer your questions today. I'm sorry to hear that this happened.
An agreement that someone will pay rent week to week IS a lease agreement. The problem is, the landlord can terminate at any time with 7 days written notice. S.C. Code of Laws, Section 27-40-770. The landlord doesn't need a reason for refusing to renew a week to week lease. Your son would be protected by laws giving him 14 days to repair the problem if he had a month-to-month lease, but here, the landlord doesn't have to give him a chance before terminating the lease.
If he can remove the dog ASAP, he may be able to get the landlord to reconsider.
A landlord is only allowed to keep a tenant's security deposit for unpaid rent and actual damage to the property. The landlord will have to return his deposit, and he can sue if they don't.
