Dear Mr. Out-of-State Landlord..

That as of July 22, 2011, changes in the Washington State Residential Landlord Tenant Act allow for an out of state landlord who violates the LT Act to be sued in Washington State?
Regardless of such designation, any owner who resides outside the state and who violates a provision of this chapter is deemed to have submitted himself or herself to the jurisdiction of the courts of this state and personal service of any process may be made on the owner outside the state with the same force and effect as personal service within the state.

This means that even though you live in (Hawaii) your tenants can still sue you for violations, and you will need to come back to WA for the court process. Keep this in mind as flights can get pricey, last minute. You may not be able to recoupe your travel costs if you lose.
