The five highest-priced home sales reported in Diablo Valley–East County, California for the week ending November 8, 2026, added up to $17.469 million. Every one was a single-family home in Contra Costa County: two in Lafayette, both on Happy Valley Road, and three in Walnut Creek, including a pair in the Northgate neighborhood.
The group runs from a home finished in 2009 to one built in 1947, and from a gated property of nearly an acre to a shingle-sided ranch on about a quarter acre. Pools turn up at three of the five, and two of the homes have owned solar systems paired with Tesla Powerwall batteries.

The week’s top sale was 3937 Happy Valley Road in Lafayette, which sold for $8,125,000. A gate and a private, winding drive lead into the 0.92-acre property, the largest lot in this Top 5, and it has views of hills and trees.

The home has six bedrooms, six bathrooms and 5,740 square feet of living space, the most of the group. Its exterior combines stone with wood shingles.

Several sets of French doors open to the backyard. The primary suite has its own door to a patio, a spa-style bath and two walk-in closets fitted with cabinetry by Lloyds Custom Cabinets. An Elan smart-home system, a sound system throughout and solar panels with Tesla Powerwall battery backup are among the systems.

No. 3 — $2,400,000 · 3611 Vista Charonoaks, Walnut Creek, California
The story of 3611 Vista Charonoaks, which sold for $2,400,000, is one of two eras. The home in Walnut Creek’s Northgate neighborhood was built in 1949, and a large addition followed in the mid-1980s. Today it has four bedrooms, four bathrooms and 4,643 square feet, with a floor plan that suits extended family or guests. The listing says the home could use some updating and maintenance.
The original part of the home keeps its redwood woodwork and wainscoting, and a circular staircase connects the floors. There are three fireplaces. The formal dining room has a beamed ceiling, and a leisure room is built around a wood-burning stove. The addition centers on a vaulted great room with a full wet bar, a stained-glass piece and a side patio. A breakfast room sits next to the kitchen, and the main level also has a wine closet and a pantry.
There are two primary suites. The upstairs suite has wood-beamed ceilings, a sitting area, a fireplace and a private deck with views of Mount Diablo, along with two walk-in closets, a tiled walk-in shower and a tub with a view of the pool. The second suite, on the main level, has its own full bath.
The 0.72-acre corner lot is on a cul-de-sac. Along with the swimming pool and a shaded pool house, the grounds have fruit trees, a workshop and a chicken coop. A gated concrete pad provides parking for an RV or boat, and the home also has a three-car garage and a second driveway. The neighborhood is close to the Contra Costa Canal Trail, Arbolado Park and the Valley Vista Golf Course.
