I have been prescribed a companion animal. My landlord wants to charge me 1000.00 dollars for a deposit. Is this legal. If I get the animal, does the 6 month rule apply as far as retaliatory behavior on the part of the landlord? Is my landlord able to ask me to move in month 7? Retaliatory behavior on the part of a landlord goes for 6 months in other areas of the law, does it apply here?
