Do I have to remove an old wood stove before selling my Washington home?

Seattle Fireplace & Chimney · October 18, 2026

What the law actually says

There is a lot of wrong information on this question, including on some contractor websites that tell Washington sellers an old stove must be destroyed before closing. The state's own answer is plain. The Department of Ecology's wood stove page says removing an uncertified wood stove is not required when you are buying or selling a house.

State law goes further. RCW 70A.15.3600 says that where a local area does ban uncertified devices, it cannot add separate time-of-sale obligations on sellers or buyers. The one thing the law allows at sale is the seller disclosure under RCW 64.06.020. So there is no wood stove removal-at-sale rule anywhere in the Puget Sound Clean Air Agency area, and none in Washington.

What you do have to disclose

Washington's seller disclosure statement, known as Form 17 and set out in RCW 64.06.020, asks about the stove directly. Section 5.C asks whether the property has a woodstove, fireplace insert, pellet stove or fireplace, and whether the woodstoves or inserts are EPA-certified. Section 4.F asks about defects in chimneys, woodstoves and fireplaces.

That means you need to know two things before you fill it out: whether the stove is certified, and whether the stove and chimney have problems. Guessing is the part that causes trouble later. If you are not sure, find the label (our post on telling whether a stove is EPA-certified walks through it) or have it looked at.

Form 17 also asks, in section 5.E, whether the home has carbon monoxide alarms. Under RCW 19.27.530, a seller must equip the home with CO alarms before a buyer may legally move in, for any sale on or after July 26, 2009. A house with a wood stove or gas fireplace is exactly where those alarms matter.

The one real exception: Tacoma-Pierce County

Inside the Tacoma-Pierce County Smoke Reduction Zone, using an uncertified wood stove or insert has been illegal since October 1, 2015, and PSCAA says those stoves must be removed and recycled or rendered inoperable unless the home has an approved exemption. This is a rule about use, not about sale, and it applies only inside the zone, not to all of Pierce County. Check the zone map on PSCAA's page (pscleanair.gov/547) before you decide anything; we do not guess which addresses fall inside it.

If your house is in the zone and still has a working uncertified stove, the buyer cannot legally use it either. Dealing with it before you list is usually simpler than having it come up in negotiation.

What you cannot do with the old stove

Ecology is equally clear on the other side. You cannot sell, exchange or give away an uncertified wood stove. RCW 70A.15.3520 says a used solid fuel device may not be installed in a new or existing building unless it meets Oregon DEQ Phase II or EPA certification. And Ecology notes that a homeowner cannot apply to certify their own stove. So the stove stays with the house, or it goes to a recycler.

• Leave it in place and disclose it honestly on Form 17.
• Remove it and recycle it, which may qualify for PSCAA's $500 recycling payment.
• Replace it with an EPA-certified stove or insert, or a gas insert, before you list.
• Remove it and close the opening, leaving the masonry fireplace or chimney.

Is the $500 recycling payment worth it before a sale

The PSCAA Wood Stove Recycling Program (pscleanair.gov/409) pays homeowners in King, Kitsap, Pierce and Snohomish counties $500 to recycle an uncertified stove or insert, or a certified one that does not meet the 2020 EPA standard. The stove has to be in working order, PSCAA reviews photos before recycling, and the owner is responsible for removing it and taking it to an approved recycler. Pellet stoves, gas units, zero-clearance fireplaces, barrel stoves, cook stoves and brick fireplaces do not qualify.

If you plan to replace it, an EPA-certified wood stove installed typically runs $3,000 to $8,000 and a gas insert $2,000 to $8,000. Do not count on a federal tax credit: HPBA notes the 25C biomass stove credit (30 percent, up to $2,000) expired after December 31, 2025.

How we help sellers

Our inspection is free. We check the stove label, look at the stove, connector and chimney top to bottom, take photos and give you a written price for anything that needs work. That gives you real answers for sections 4.F and 5.C of Form 17, and it gives the buyer's inspector less to find. Bookings run Sunday to Friday in 3-hour windows, and we call to confirm.
