There are statutes that control evictions, whether commercial or residential, but there is no analogue to the RLTA. It depends on what your contract says. It would be irresponsible to try to interpret a lease without reviewing it.
You can recover your attorney fees and costs of suit from your tenant. It would be vastly cheaper to lawyer up now , have this done professionally and rest assured it is done correctly, rather than asking random questions. I am sure you are good at what you do, but unless you regularly practice landlord-tenant law in your jurisdiction, you are very likely to miss something.
Also, if a company owns the real property, you cannot represent the company in court without a law license. Signing a complaint containing an allegation that you are the owner when a corporation, even if you are the sole owner of the corp., would be a basis to get yourself sanctioned.
Seriously, it's time to lawyer up. Elizabeth Powell
Using Avvo does not form an attorney client relationship.
Commercial property leases are contracts. The written terms of the contract can be binding. Washington law regarding landlord and tenant can be seen at RCW 59 (http://apps.leg.wa.gov/RCW/default.aspx?cite=59).
[Residential leases are, of course, different from commercial leases.)
