"SEC. 80. Forcible entry into and detainer of land or buildings.—Any one deprived of the possession of any land or building by force, intimidation, threat, strategy, or stealth, and any landlord, vendor, vendee, or other person against whom the possession of any land or building is unlawfully withheld after the expiration or determination of the right to hold possession, by virtue of any contract, express or implied, and the legal representatives or assigns of any such landlord, vendor, vendee, or other person, shall at any time within one year after such unlawful deprivation or withholding of possession be entitled, as against the person or persons unlawfully withholding or depriving of possession, or against any person or persons claiming under them, to restitution of the land, building, and premises possession of which is unlawfully withheld, together with damages and costs: Provided, however, That no landlord shall commence any action against a tenant for restitution of possession of any land for failure to pay rent or to comply with the conditions of his lease, unless the tenant shall have failed, for a period of fifteen days, or five days in the case of a building, to pay the rent due or comply with the conditions of his lease after demand therefor. The demand for payment or for the performance condition of the lease may be made upon the tenant personally, or by serving written notice such demand upon any person who may be found up the premises or by posting such notice on the premises if neither the tenant nor any other person can be found thereon at the time the landlord or his agent may have there for the purpose of making such demand."
