There are certain actions your landlord is not allowed to take, no matter what the situation. A landlord cannot shut off utilities, take anything that belongs to you, change the locks or otherwise lock you out of your apartment to force you to pay rent or leave the apartment. A landlord also cannot raise the rent or threaten to evict you for taking legal action against the landlord. You might want to consult professional legal counsel if either situation arises. A landlord is not permitted to abuse the right to enter the apartment, meaning that the landlord is not allowed to harass a tenant with repeated visits.
