The law varies from state to state. Yes a landlord can evict you on late payment of the rent. It doesn't matter if you are 15 days late or 1 month late. You now have right of defense and can present the facts in the court. You can be saved and remained on the property if you pay full rent at once.

 It could be legal to some extent because you didn't tell him when you had to pay. In any case you would informed him about your delays. But sometimes it depends what kind of land you have. So I would suggest this if possible find a better place to stay because even if after payment, you wont be at peace. Thank you
