can you have 2 stoves in one house with two apartments?

It's very plausible that there are zoning laws such as you write about. Rentals are held to certain standards and you have to remember that most homes later converted to rentals were obviously not planned or built for that purpose at their original time of building. There's nothing complicated about this concept. Rentals are everywhere. Just look elsewhere-problem solved. If you don't want to move then you have to deal with what you have. You signed the lease so now you have to deal with what you're signed to-that's just being an adult. Like anything else in life when you don't like a situation it's up to you to make appropriate shifts so things are better. Next time choose better, plan ahead a little better and find something that works for you better next time you're looking for a place. Complaining about your own choice after the fact only makes yourself look bad. Consider this a lesson in life that will hopefully serve you well as you grow up.

I doubt he is just being cheap by not putting a stove in as that would certainly make it a more attractive rental...Like one of my peers said there are specific codes that regulate rentals and these vary city to city and state to state....There is no specific document I can think of but you can contact your local building,fire, and code officials for answers.

Yes, I agree with the answer above...

yes you can
