Okla. Stat. tit. 41, § 41-117: Commencement of tenancy - Delivery of possession -

Wrongful possession - Limitations on use - Rights regarding

occupants - Reasonable occupancy limitation.

A. At the commencement of the term a landlord shall deliver

full possession of the premises to the tenant in compliance with the

rental agreement and Section 118 of this title. Except as otherwise

provided in this act, the landlord may bring an action for

possession against any other person wrongfully in possession and may

recover his damages.

B. A rental agreement may provide reasonable limitations upon

use of a dwelling unit or premises by a tenant or occupant. A

landlord shall have the right to demand that an occupant vacate the

dwelling unit or the premises or both if such occupant breaches any

condition of the rental agreement which would be enforceable against

the tenant. If a landlord makes a written request to the tenant or

to the occupant for the occupant to depart from the dwelling unit or

the premises or both, the occupant shall comply. If the occupant

wrongfully fails to comply within a reasonable time, the occupant

shall, upon conviction, be deemed guilty of a trespass and may be

punished by a fine of not to exceed Five Hundred Dollars ($500.00)

or by confinement in the county jail for a period not to exceed

thirty (30) days or by both such fine and imprisonment.

C. An occupancy limitation of two (2) persons per bedroom

residing in a dwelling unit shall be presumed reasonable for this

state. The two-person limitation shall not apply to a child or

children born to the tenants during the course of the lease.
