Largely depends on the city and state in which you reside. As far as I am aware, besides discrimination based on race, protection against rent increases is handled different across each state and city.

NYC for example has better tenant rights and prevention of unreasonable rent increases. On the other hand, TX has very basic tenant rights and no regulations on rent increases.
