Buying a House With a Wood Stove or Fireplace in Snohomish or King County (2026)

Short answer: A wood stove or fireplace doesn’t stop a sale in Snohomish or King County, and Washington doesn’t make the seller remove an uncertified stove before closing. What it does do is limit how you can use it. Burn bans restrict which devices can run, an uncertified stove can’t be sold or reinstalled somewhere else, and a home inspection only covers part of the chimney. Read the seller’s Form 17 answers, look for the EPA label, and budget for a chimney professional if you plan to burn.

This is general information, not legal, fire or insurance advice. Burn ban status, installation permits and insurance rules can change, so check with the Puget Sound Clean Air Agency, the local building department and your insurer.

What the seller has to tell you

Washington’s seller disclosure form, Form 17, asks whether the property has a woodstove, fireplace insert, pellet stove or fireplace (Item 5C). If there’s a woodstove or insert, it asks whether all of them are certified by the U.S. Environmental Protection Agency as clean burning. The form also asks about defects in chimneys, fireplaces and woodstoves (Item 4F). RCW 64.06.020 currently has two versions on the Legislature’s site: one marked effective until January 1, 2027, and one effective January 1, 2027. The questions quoted here appear in both. If your sale runs across the new year, check which form is being used.

That disclosure is the only time-of-sale requirement. RCW 70A.15.3600 lets air agencies restrict uncertified devices, but says a restriction can’t put separate time-of-sale obligations on the buyer or seller, except the Form 17 disclosure of wood burning appliances. Ecology’s wood stove page says it plainly: removing an uncertified wood stove is not required when you buy or sell a house. The Puget Sound Clean Air Agency does require removal in the Tacoma-Pierce County Smoke Reduction Zone, which took effect October 1, 2015, but that zone is in Pierce County.

Certified or not: why it matters

Under Washington’s definitions in RCW 70A.15.3510, a fireplace insert counts as a woodstove. The Puget Sound Clean Air Agency says only EPA-certified wood stoves and fireplace inserts have been sold in Washington since 1992, and that uncertified stoves release twice as much air pollution as certified ones. To check, look for an EPA label on the back or side of the stove. On an insert, you may need to remove the decorative surround to see it.

Based on: Washington Department of Ecology, Wood stove information page; WAC 173-433-150; WAC 173-433-100; RCW 70A.15.3520. Both burn ban stages exempt a home that has no adequate source of heat other than the device (WAC 173-433-150; RCW 70A.15.3600(6)).

Some other rules apply whatever the device. WAC 173-433-110 sets a statewide smoke limit of 20% opacity averaged over six consecutive minutes in any hour, with a 20-minute allowance when starting a new fire. RCW 70A.15.3600 bans burning garbage, treated wood, plastics, rubber, animals, asphalt products and waste petroleum products, among others, in a home stove or fireplace.

If you’d rather not keep an older stove, the Puget Sound Clean Air Agency runs a wood stove recycling program. Its page says eligible devices include uncertified stoves and inserts and certified ones that don’t meet 2020 EPA standards; pellet stoves, gas stoves, prefabricated fireplaces and brick fireplaces aren’t eligible. It pays $500 for an eligible stove, and you’re responsible for removing and hauling it. Check the page for current terms.

What the inspection covers, and what it doesn’t

Under WAC 308-408C-160, a Washington home inspector describes fireplaces and stoves, inspects accessible dampers, fireboxes and hearths, and notes anything that should go to a specialist. The inspector isn’t required to:

• Inspect flues or confirm liners beyond what can be readily seen from the roof or the firebox
• Light a fire, judge the draft, or run a chimney smoke test
• Evaluate the installation of a fireplace insert, or modifications to a fireplace, stove or chimney
• Take anything apart, including rain caps

Our guide to what a standard home inspection covers covers the rest. If you’re buying an older house and plan to change the fireplace or hearth, read our guide to asbestos in older homes before any demolition.

If the inspection or chimney check turns up a problem, what happens next depends on your purchase agreement. Our guide to contingencies explains the usual options.

FAQ

Does the seller have to remove an uncertified wood stove before closing?

No, not in Snohomish or King County. Washington’s Department of Ecology says removing an uncertified wood stove is not required when you buy or sell a house, and state law bars air agencies from putting separate time-of-sale requirements on buyers or sellers (RCW 70A.15.3600). The seller does have to answer the wood stove questions on Form 17.

How do I tell if a wood stove is EPA certified?

Look for an EPA certification label on the back or side of the stove. On a fireplace insert, the Puget Sound Clean Air Agency says you may need to remove the decorative surround to see it. If you’re still unsure, the agency suggests taking photos of the front, back and label to a hearth dealer.

Can I use a wood stove during a burn ban?

It depends on the stage and on whether the house has another adequate heat source. During a Stage 1 burn ban, only EPA-certified wood stoves and nonaffected pellet stoves can be used. During Stage 2, no wood stove, fireplace or pellet stove can be used. Both bans exempt homes without another adequate source of heat (WAC 173-433-150).

Will the home inspector check the chimney?

Only partly. Washington’s inspector standards say the inspector describes fireplaces and stoves and inspects accessible dampers, fireboxes and hearths, but isn’t required to inspect flues beyond what can be readily seen, test the draft, run a smoke test, light a fire, or evaluate an insert’s installation (WAC 308-408C-160). A chimney professional can look further.

Can I sell or move an old uncertified stove after I buy the house?

You can’t sell or give it away in Washington. WAC 173-433-100 bars selling, offering, exchanging or giving away a solid fuel burning device unless it’s certified, and Ecology says a homeowner can’t certify a stove. RCW 70A.15.3520 also bars installing a used stove unless it’s certified. The Puget Sound Clean Air Agency runs a recycling program for eligible stoves.
