Can I Make My Landlord Pay The Costs For Moving Expenses Or Even Sue Him? It Costs A Lot Of Money To Move.

I talked to the city and they said that my landlord was renting my apt to me illegally. I live above a garage and gas fumes come up to the apt, the steps need to be repaired, have nails sticking out and no handrail. He has made no effort to fix this. He gets very angry if I talk to him about repairs. I feel these repairs are very dangerous city said it probably wouldn't pass inspection and I would have to move.
