fair rent increase

I own a three family brownstone in clinton hill / bed-stuy. I have two two bedroom apartments that i have been renting to the same two tenants for over 4 years each. they currently pay $1280 and $1300 for their apartments and I have never raised their rent. I would like to raise it now but want to be fair and legal, does anyone what the legal percentage is that it can be raised every year? I’m thinking to raise each of their rents by $75 – $100 a month. comments? advice?
