Jim Sinegal House: Hunts Point Home and Napa Estate

Costco co-founder Jim Sinegal owns one of the most talked-about private homes in Hunts Point, Washington.

The Lake Washington community is known for rare waterfront properties, large lots, and a level of privacy that attracts prominent business leaders.

The residence entered the national spotlight in 2012 when Jim and Janet Sinegal hosted a presidential fundraiser there.

Unlike many high-profile estates, however, the home has never been publicly marketed with a verified price, floor plan, or room-by-room tour. Here is what the available record reveals about the property—and which widely repeated claims still lack proof.

Jim Sinegal’s house is in Hunts Point, an incorporated residential community on the eastern shore of Lake Washington. The setting places the home across the water from Seattle in one of the region’s smallest and most private waterfront enclaves.

The property is often described online as an 8,370-square-foot mansion worth $38 million.

Those figures appear on mapping and celebrity-home sites, but they are not supported by a public listing or two reliable property sources. They should not be treated as confirmed facts.

Where Is Jim Sinegal’s House?

Jim Sinegal’s home is in Hunts Point, Washington, according to regional news coverage. The Puget Sound Business Journal identified the house as the Hunts Point residence of Jim and Janet Sinegal when it covered a 2012 fundraiser there.

Realtor.com has also named Sinegal among the prominent residents associated with the community. That is more reliable than blogs that switch between Hunts Point and Medina as if the two names describe the same place.

They do not.

Hunts Point and Medina are separate municipalities on the Eastside of Lake Washington. Both are known for high-value waterfront homes, but an article about Sinegal’s residence should use Hunts Point unless a new authoritative source establishes otherwise.

Why Hunts Point Is a Distinctive Real Estate Setting

Hunts Point is a narrow peninsula that extends into Lake Washington.

Its limited land area, waterfront access, mature trees, and proximity to Bellevue and Seattle make residential inventory unusually scarce.

The community is associated with private estates rather than dense development. Large parcels can offer lake frontage, docks, long drives, and views toward Seattle. Those are characteristics of the local luxury market, not confirmed features of Sinegal’s specific property.

Local sales show how much the site itself can influence value. In 2020, the Puget Sound Business Journal reported a $60 million sale at the tip of the peninsula. That transaction concerned a different estate and should not be used to assign a value to the Jim Sinegal house.

What the 2012 Obama Event Confirms About the Home

The July 2012 fundraiser confirms that the Sinegal residence could host a significant private gathering.

Both the Puget Sound Business Journal and SeattlePI reported that President Barack Obama attended an event at the former Costco chief’s home.

That coverage verifies the occupants, the location, and the home’s use as an event setting. It does not provide a measured floor area, architectural style, room list, or listing-quality photographs.

This distinction matters.

A news report about a gathering can establish that an event took place at a residence. It cannot support later claims about a home theater, infinity pool, imported finishes, or a particular interior color scheme unless those details appear in the reporting.

Is the House Really Worth $38 Million?

No dependable public source reviewed for this update confirms a $38 million value for Jim Sinegal’s house. The number appears mainly in recent celebrity-house articles that do not identify a sale record, appraisal date, listing agency, or valuation method.

A property value can also mean several different things.

An assessor’s taxable value, a broker’s listing price, a buyer’s sale price, and an automated estimate are not interchangeable. Each needs a date and a named source.

The broader local market proves that the community contains exceptionally valuable real estate. It does not prove the price of one private residence. Until a credible transaction, listing, or public assessment connects a figure to this property, its value is best recorded as not publicly confirmed.

The 8,370-Square-Foot Claim Remains Unverified

Several house-focused sites describe the residence as 8,370 square feet on about 1.56 acres with 165 feet of waterfront.

The consistency may look convincing, but repeated wording does not equal independent confirmation.

No accessible listing from a recognized brokerage or property report from a regional real estate outlet was found to verify that set of numbers. The same issue applies to claims of 4 bedrooms and 4.25 bathrooms.

For that reason, these measurements are included only to explain what readers may encounter elsewhere. They are not used as established specifications in the summary table.

What Is Known About the Interior and Architecture?

The residence’s interior design and architectural authorship are not publicly documented in reliable coverage.

There is no verified room-by-room tour that supports the detailed wood ceilings, fireplaces, reclaimed materials, and luxury amenities described by some blogs.

Photos of neighboring estates cannot fill that gap. Homes in the community range from older Northwest residences to large contemporary compounds. Using a neighboring listing to describe Sinegal’s rooms would misidentify another property.

The most defensible picture is therefore limited: a private waterfront residence capable of hosting notable guests, situated within a highly exclusive Lake Washington housing market.

Jim Sinegal’s Hunts Point Home Is Not Sinegal Estate

The Hunts Point residence and Sinegal Estate in St.

Helena, California, are different properties. Mixing them creates incorrect ownership, location, and design claims.

Jim’s son David Sinegal acquired the historic Inglewood Estate winery property in 2013.

The San Francisco Business Times reported an estimated $20 million purchase, while Wines & Vines later reported a $17 million figure. Because the contemporary reports differ, the price should be presented as reported rather than settled fact.

The estate’s published history describes a 30-acre property with a Victorian house, a 2-acre lake, gardens, olive orchards, a poolside cabana, and 6,500 square feet of underground wine caves. Architecture firm Signum also confirms that it reworked the winery experience while preserving the historic setting.

Those features belong to the St. Helena winery estate, where David and his family have lived. They should not be transferred to Jim and Janet Sinegal’s Washington residence.

A Clear Property Timeline

• Before 2012: Jim and Janet Sinegal were established residents of Hunts Point, based on later event coverage.
• July 2012: Regional outlets reported a Barack Obama fundraiser at their Hunts Point home.
• 2013: David Sinegal acquired the former Inglewood Estate in St. Helena and began developing Sinegal Estate.
• 2014: Seattle Times political coverage again referred to an Obama-related event at the former Costco CEO’s house.
• As of August 2026: No dependable public listing or sale report establishes that the Hunts Point property changed hands.

What Can Be Said With Confidence

Jim Sinegal is associated with a private home in Hunts Point, Washington.

Multiple regional outlets support that location, and documented political events connect Jim and Janet Sinegal to the residence.

The public evidence stops short of a verified purchase price, current value, floor area, bedroom count, architect, or interior tour. Publishing those missing figures as estimates would create more detail, but less accuracy.

The property’s strongest real estate story is its setting: a scarce Lake Washington community known for privacy, waterfront land, and very high-value homes.

That context explains the interest without turning unverified specifications into facts.
