I did not. He is on a month to month lease and we just want him out regardless. I hope that is not an issue. Besides the city coming down on the property twice he has other issues like having his son staying there with him longer that the lease states he should and him and his son fight all the time. Severel times the police have been called. He has trailers park all in the yard not just where there is a driveway. He is just not a good renter.
Then you need to serve a proper notice of nonrenewal. In most states that is 30 days (if a literal state) or one full rental period (if a term state). It is highly unlikely that your 20 day notice is valid. You need not state a reason for the nonrenewal (in most states).
If he's month to month, you can give him a 30 day notice of non-renewal then. It's not an eviction technically, but you're getting him out. Then after the 30 days if he still doesn't leave, then you have to file a court case for an unlawful detainer. If you win that, then the courts give him a set time he must be out by and if he is not, then they force him out.
