There is no local eviction or rent ordinance at
You should be able to evict him using a 30 day notice, according to
Texas Property Code:
TITLE 8. LANDLORD AND TENANT
CHAPTER 91. PROVISIONS GENERALLY APPLICABLE TO LANDLORDS AND TENANTS
Sec. 91.001. NOTICE FOR TERMINATING CERTAIN TENANCIES. (a) A monthly tenancy or a tenancy from month to month may be terminated by the tenant or the landlord giving notice of termination to the other.
(b) If a notice of termination is given under Subsection (a) and if the rent-paying period is at least one month, the tenancy terminates on whichever of the following days is the later:
(1) the day given in the notice for termination; or
(2) one month after the day on which the notice is given.
There is a 30 day notice form linked from
https://wikidownload.com/wiki/texas-eviction-notice-forms/ that you can use as a model.
You can get a free consultation from some of the local landlord tenant attorneys listed here.
If he does not leave after 30 days you will need to consult a local attorney.
In general a month to month rental can be terminated by either landlord or tenant on 30 days notice for no reason, and the notice does not need to state any reason.
I hope this information is helpful.
