Rancho del Diablo is where a lot of people get their first look at Concord's Eichlers. It's a compact neighborhood of about 70 homes on a few blocks off Mendocino Drive, with Mount Diablo rising behind the rooflines. It's also a famously social neighborhood. I've sold a number of homes here, including a square-footage record sale for a Rancho del Diablo Eichler. Here's my guide to the neighborhood for anyone curious about Eichler homes in Concord, CA.
A Little History: The "Devil's Ranch"
Joseph Eichler built three tracts in Concord between 1963 and 1965: Parkwood Estates, Rancho del Diablo and Rancho de los Santos. According to the Eichler Network, Rancho del Diablo has 69 homes. The name almost certainly comes from Mount Diablo, which looms over the neighborhood. When Eichler followed it with a smaller tract a few blocks west, his architects filed that one as "Rancho del Diablo #2." Today it's known as Rancho de los Santos, the "ranch of the saints" to Diablo's devil.
Sources date the tract to 1963 or 1964. County records for the homes I've sold here list 1963, and the Eichler Network dates the neighborhood to 1964, so it's fair to say the homes were built in 1963 and 1964.
Who designed these homes?
Two of Eichler's main architecture firms worked here. Claude Oakland is credited with the pitched-roof atrium model; I listed a former Eichler model home of that design in 2022, and Dwell featured it. Jones & Emmons is credited with other plans, including the pitched-roof atrium carport model, Plan OJ-1184, that I sold on Phoenix Street. When the paperwork and the plan number disagree, the plan number is the best place to start.
What the Homes Are Like
Neighbors and registries describe three basic floor plans in Rancho del Diablo, two with atriums and one without:
- Pitched-roof atrium model: about 1,795 square feet, four bedrooms and two baths, with a two-car garage.
- Carport atrium model: about 1,656 square feet, four bedrooms and two baths, with a pitched roof and carport.
- Flat-roof model: about 1,367 square feet, three bedrooms and two baths, with no atrium.
All three share the classic Eichler look: post-and-beam framing, tongue-and-groove ceilings, walls of glass and sliding doors to the yard. The homes I've sold here sit on lots of about 7,100 to 8,100 square feet, and many have backyard pools.
Original details are surprisingly common. I've sold homes here with their original Eichler kitchen and bath, mahogany paneling and interior doors, unpainted tongue-and-groove ceilings and working radiant floor heat. According to its owner, the 2022 model home still had the globe lights Eichler installed in model-home garages, which doubled as sales offices.
Streets and Location
Rancho del Diablo is in Concord's 94521 ZIP code, on Phoenix Street, Sacramento Street and Wilson Lane, just off Mendocino Drive and east of West Street. Rancho de los Santos is only a few blocks away, and the two neighborhoods are nearly contiguous.
Concord BART is about two miles west in a straight line, which matters if you commute toward Walnut Creek, Oakland or San Francisco. Shopping along Clayton Road is close, downtown's Todos Santos Plaza is a little over two miles away, and Newhall Community Park is about a mile off. Highway 242 and I-680 are a short drive.
The neighborhood is in the Mt. Diablo Unified School District, and Westwood Elementary is a few blocks away. School boundaries can change, so always confirm an address's assigned schools with MDUSD.
Living in Rancho del Diablo
This is a neighborhood that likes to get together. The Eichler Network has written about monthly "Spaghetti Sundays," holiday parties and a Fourth of July "Hodgepodge Parade" with decorated bikes and a marching band. Neighbors in Diablo and Los Santos tend to know each other, and owners swap leads on hard-to-find Eichler materials like mahogany siding. There's no HOA and no shared tract amenities. What brings people together is the architecture and the street.
Keeping a 60-year-old Eichler comfortable takes some work. Recent sellers here have added owned solar, newer roofs and radiant boilers, and updated kitchens and baths, usually without erasing the period details. If you're planning a kitchen update, my post on kitchen design trends shaping East Bay homes covers how warm wood ties back to Eichler post-and-beam character.
Buying an Eichler in Rancho del Diablo
With only about 70 homes, listings here are infrequent. A few things I tell every buyer:
- Know which of the three plans you're looking at. The flat-roof, carport atrium and pitched-roof atrium models live very differently, and square footage alone doesn't tell you that.
- Inspect the systems that matter. Radiant heat, roofing and drainage, electrical and windows deserve an inspector who knows Eichlers. Pools need their own look, too.
- Value originality. An original kitchen, intact mahogany or unpainted ceilings are hard to recreate and often worth more than a generic remodel.
- Be ready. Have financing lined up and let me know what you're looking for, so you hear about homes as they're coming.
Selling Your Rancho del Diablo Eichler
Eichler buyers are paying for architecture, so the marketing, photography and staging have to show it. These are homes I've represented in Rancho del Diablo:

Each of those homes sold on an honest story: what's original, what's been improved and why it matters. If you're thinking about selling, start with a home valuation, and I'll walk you through what Eichler buyers in Concord are paying for right now.
