RCW 59.18.270
Moneys paid as deposit or security for performance by tenant - Deposit by landlord in trust account - Receipt - Claims.
All moneys paid to the landlord by the tenant as a deposit as security for performance of the tenant's obligations in a lease or rental agreement shall promptly be deposited by the landlord in a trust account, maintained by the landlord for the purpose of holding such security deposits for tenants of the landlord----
I personally know of only one landlord that holds his deposits in an escrow account.. Not saying its an ethical angle, but it is the law, If you never received a deposit slip regarding the safekeeping of your deposit, you can demand that deposit due.....
Secondly,
"No deposit may be collected by a landlord unless the rental agreement is in writing and a written checklist or statement specifically describing the condition and cleanliness of or existing damages to the premises and furnishings, including, but not limited to, walls, floors, countertops, carpets, drapes, furniture, and appliances, is provided by the landlord to the tenant at the commencement of the tenancy."
No checklist=No claim against the deposit.
And last but not least, (if you go to court)
RCW 59.18.280
"The court may in its discretion award up to two times the amount of the deposit for the intentional refusal of the landlord to give the statement or refund due. In any action brought by the tenant to recover the deposit, the prevailing party shall additionally be entitled to the cost of suit or arbitration including a reasonable attorney's fee."
These are just some exerps from Chapter 59.18 RCW
Residential landlord-tenant act of Washington State. That said, C'mon guys, You cant reasonably expect the tenant of 7 years to replace the carpet due to 3sq/ft of stain. If the tenant was "living tike a pig" for seven years, why in the heck wouldn't you have gotten rid of them a little earlier, you reap what you sew.
The federal government claims that residential carpet has a "reasonably expected useful life" of 7-years... Also, Carpet should be depreciated in 20% blocks, or, 5 years.
After 7 years of tenancy, the landlord has no reasonable claim to the carpet being in excess of "reasonable wear from normal use".
But TACT is a whole different issue... For good measure, Should you have the carpet cleaned? Yes
Does the landlord have a foot to stand on? No
