No, you have to be notified IN WRITING of any lease changes 30 days (in most states) before changes are to take effect. A good landlord would ask his tenant to at least initial any lease changes. He cannot however raise your rent until your lease is up. When its up he can charge you whatever he wants. If he is a private landlord and not a gov program etc.
No, your landlord cannot change your lease without your consent.
only with the permission of the landlord in writing
The landlord has many responsibilities under the law. Whether they are spelled out in the lease or not doesn't change that. The lease can add responsibilities for the landlord.
No, the landlord has not returned the signed lease to you.
Renters make a lease agreement with a landlord.
No.
Yes the landlord can be sued for breaking the lease.
No. A lease is a legally binding contract, which obligates both the landlord and tenant to a tenancy for the term of the lease. If you and the landlord both signed a lease, and the landlord refuses to give you occupancy of the property, you need to see a landlord-tenant attorney or tenant's rights group immediately!
Yes, unless the landlord breached the lease in some significant way.
Yes he can. A violation of the terms of a lease by a landlord is just as much grounds for termination by the tenant. The landlord can still evict you but less likely will win.
Yes, you can break your lease if your landlord refuses to fix things, as long as this is specified in the lease. Your landlord is liable for keeping the home in working order and safe. Contact an attorney to help you with the lease.
They can change conditions upon renewal. Not sure if they can do this if it is not on the lease. Read your lease: it may be that they failed to collect it at the time.
