How do I find out what the "useful life" of a carpet is under Washington State landlord tenant law?

There is no statutory definition of "useful life." You simply provide evidence to convince the judge. The IRS publication that Glenn S cited is a good start. Also, you can obtain manufacturer's brochures from a local carpet store. All you need to do is provide convincing evidence that a carpet's reasonable useful life is less than 20 years.

Just go to the Washington State website and click on consumer rights. If you have lived there for 20 years, they can't charge you anything for normal wear and tear.

There is no such thing as a useful life law. Tenants are responsible for cleaning their carpets.
