Selling an Inherited Home in Snohomish County: Everett to Bothell

By Jack Macdonald

If you've inherited a house anywhere from Everett down to Bothell, there's one date worth circling: November 1, 2026. That's when a new Snohomish County septic rule for home sales takes effect, and a lot of estate houses in this county sit on septic systems nobody has looked at in years.

So this post starts there, then covers where the probate case lives and how different the houses are from one end of the county to the other.

The new septic rule, in plain words

On April 14, 2026 the Snohomish County Board of Health adopted an ordinance adding septic requirements for real estate transactions to the county health code. It takes effect November 1, 2026.

The exact requirements for sellers are in the adopted rule and the Health Department's guidance for it, and that's what to go by. While the rule was being drafted, the Health Department's materials described an inspection by a certified septic professional and a report the seller passes on to the buyer. Those were draft materials, so confirm the final requirements, timing and any fees with the Snohomish County Health Department before you plan around them.

Whatever the final details, a septic report that turns up problems is something buyers will see and price in.

What that means for an estate

Washington's seller disclosure law treats a sale by a personal representative differently from an ordinary sale. How that plays with the new septic rule is a question for your estate attorney and the Health Department, so ask early instead of assuming you're in or out.

Practically, I'd get the inspection on the calendar soon either way. An empty house with an old system is exactly where surprises live. Finding out before you list turns a repair into a number you plan around, not a fight in the middle of escrow.

Where the probate case gets filed

If the estate is opened in Snohomish County, it goes through Snohomish County Superior Court in Everett, and the Superior Court Clerk's office there takes probate filings.

Something families don't always know: Washington generally lets the person petitioning pick the county where probate is opened. In some situations it has to be the county where the person lived, and other parties can ask to move it. So a family living in Bellevue might open the case in King County even though the house is in Lynnwood. Your attorney will choose what makes sense. For the sale itself, what matters is who has authority to sign, not which courthouse holds the file.

One county, very different houses

Snohomish County covers a lot of ground, and the right prep depends on where the house sits.

Everett

Everett has plenty of older homes on city lots near downtown and the north end, plus newer subdivisions farther south. Older houses tend to come with older wiring, plumbing and roofs. That's where an inspection before listing earns its keep, so you know what a buyer's inspector will find before they find it.

Mill Creek and Lynnwood

Much of Mill Creek is planned neighborhoods, and many of them have homeowners associations. If the house is in one, request the HOA documents early. Buyers will need them, and an estate can have unpaid dues that built up after the owner passed. Lynnwood mixes older ramblers and split levels with condos and townhomes, and a condo brings its own stack of association paperwork.

Lake Stevens, Monroe and Snohomish

Head east and you see more acreage, outbuildings, wells and septic. These are the properties where the new rule matters most. They're also where a shop or barn full of decades of tools and projects can take longer to clear than the house.

The Snohomish County side of Bothell

Bothell sits in two counties. North of the King County line, the house is in Snohomish County, so Snohomish County's health rules and records apply even though the address says Bothell. I sell on both sides of that line, and it's worth checking which side you're on before assuming anything.

An Everett house we sold as is

This photo is that Everett home as it was listed. A plain older cottage, a lawn gone dry, and an estate that wasn't going to put money into it. We didn't dress it up or pretend otherwise.

We listed it at $499,950 and sold it as is. An offer came in within four days, and it closed at $535,000. Pricing it for the house it was, not the house it could be after a remodel, brought buyers who already knew what they were walking into.

As is doesn't mean ignoring the house. It means deciding, with real numbers, that the estate's money and time are better kept than spent. In Snohomish County there's now one more piece to that math: if the house is on septic, plan on the septic steps whether you fix anything else or not.

A sensible order for this winter

• Find out whether the house is on septic or sewer. If nobody in the family knows, a septic professional or the Health Department's records can tell you.
• If it's septic, call the Health Department early to confirm what the new rule requires for your sale and how far ahead of closing an inspection can be done.
• If there's an HOA, request the documents and a statement of any dues owed.
• Price two paths, as is and lightly prepped, before anyone spends money.

The families who have the easiest time in this county are the ones who learn about the house before buyers do. Septic, HOA, an old roof: find them first, and each one becomes a choice instead of a surprise.

Does probate have to be filed in Everett if the house is in Snohomish County?

Not necessarily. Washington generally lets the petitioner choose the county where probate is opened, with some exceptions, and parties can ask to move it. If it is opened in Snohomish County, it goes through Superior Court in Everett. Your estate attorney will decide.

Can we sell an inherited Everett house as is?

Yes, many estate homes sell as is. If the house is on septic, plan on the septic steps either way, and ask your attorney and the Health Department how the new rule applies to a sale by an estate.

Is Bothell in King County or Snohomish County?

Both. The northern part of Bothell is in Snohomish County and the southern part is in King County, so check the property record to know which county's rules apply.
