Yes. RCW 46.55.080 says that person authorizing the impound must be present at the time and place of the impound to sign an “Authorization to Impound”. Not only is this the law, but it helps protect our drivers, and actually provides a means to solve the problem with the tenant before their car is impounded. You standing there with a tow truck hooking up to their car lets your tenants know that you are serious, and greatly reduces any future parking problems you may have.
