Premises are land and buildings together considered as a property. This usage arose from property owners finding the word in their title deeds, where it originally correctly meant "the aforementioned; what this document is about".

Some people suppose that since "premises" looks like a plural, a single house or other piece of property must be a "premise"; but the word "premise" is reserved for use as a term in logic meaning something assumed or taken as given in making an argument. Your lowly one-room shack is still your premises.
