Legal Question in Real Estate Law in Washington

It would depend somewhat. Generally speaking, absolutely not. There is no legal theory of "borrow." Generally, you give people a "license" to use property, and that is what borrowing would be. If you don't know someone then how could that someone have given you a license to use it? There may be exceptions for example where using the personal property of another without their authorization (trespass to chattel) such as an emergency (i.e. necessity).
