If you are not paying rent - yes, absolutely the landlord can. If you aren't paying rent, your "refusal" has no legs to stand on.
a landlord can evict you for non-payment of rent or being consistantly late paying,,, disruptive behaviour, drug abuse, loud noise after 11pm, filthy premises, and too many people living there, these are the main reasons for an eviction. Another reason although not a common one is when the landlord wants the unit for his own use or for a person in his family.
In order to remove someone from your apartment, you will need to obtain an eviction notice. Without an eviction notice, it is illegal to remove the person from the premises.
There really aren't enough details in the question for us to understand the situation. Specifically, what does "use" mean, and does the rental agreement specifically state that you're renting the land itself? If you're renting a house next to your landlord's house and your landlord wants to put in a garden on the property, you may, or may not, have a legal leg to stand on... if it's a separate parcel of land and you're specifically renting the land he probably can't; if it's not and the rental agreement doesn't specifically mention the land, he probably can (you're not really "paying for" the land, you're paying for the dwelling and the right to use the land as needed to access the dwelling). "Right to get permission" is just confusing; I have no idea what that's supposed to mean. The landlord (or anyone else) has the right to ask you for permission to use land you're renting; that's called "freedom of speech". They don't (necessarily) have the right to use it without permission.
That has nothing to do with the tenant.
If your landlord is selling the house you have to continue paying the rent for it, whether to the old landlord or to the new one. Your old landlord will give you notice about when they have sold the property, and the new landlord will give you instructions on how to pay them the rent.
The property is in CA.
Absolutely.
No
Nothing. Just keep paying your rent. The landlord's relationship with his bank has nothing to do with you. And, if he does get foreclosed, federal law gives you lots of time before the bank can move you out.
If you are paying rent it is a debit. If you are a landlord receiving rent its a credit.
If you are on a fixed term lease, there is probably a provision in the written lease agreement that sets out the procedure for terminating the lease. If you're on a periodic (month to month) tenancy, you must give one month's advance notice. Getting out of a fixed term lease early could be difficult unless you can get your landlord to agree to it, or unless you can find a suitable new tenant to take over the balance of the lease. Otherwise you could be liable for paying rent for the remainder of the lease term, and possibly also for paying the landlord's expenses to ready the premises for reletting to a new tenant.
yes. you arer under contractual obligation to pay regardless of what is happening with the landlord
