Of all the communities I work in across East Contra Costa County, Trilogy at the Vineyards is
the one I’m asked about most. And it makes sense. It’s a genuinely exceptional place to live
— a gated, resort-style 55+ community at the foot of Mount Diablo, surrounded by vineyards,
with amenities that most people only experience on vacation.
I’ve been one of the most active agents in Trilogy since 2021. I’ve represented buyers who fell
in love with it and sellers who were ready to move on. I know the floor plans, the HOA, the
streets, the personality of different sections of the community, and what the resale market has
done over the past several years.
This post is everything I’d tell you over coffee.
What Trilogy at the Vineyards Actually Is
Trilogy at the Vineyards is an age-restricted (55+) master-planned community built by Shea
Homes, one of the most respected active adult builders in the country — recognized as
America’s Most Trusted Active Adult Resort Builder for 13 consecutive years.
Construction in the community began in 2006 and it is now fully built out, meaning there are no new homes
available from the builder. Every home on the market today is a resale.
The community spans six collections with 21 different floor plans, ranging from approximately
1,468 to 3,854 square feet. All homes are single-story, single-family detached residences — a
significant draw for buyers who want the independence of a standalone home without stairs. (There was a "loft" option on a few of the larger floor plans, so I guess there are handful of units with stairs. But those are for kids and grandkids to have more room when they visit.)
All the homes built after 2010 were built with solar. They had 20 year pre-paid Tesla leases included in the price.
At the heart of the community is Club Los Meganos, a 34,000-square-foot amenity center with
indoor and outdoor social spaces, two pools, tennis courts, bocce ball, fitness facilities, a full
calendar of clubs and events, and the kind of infrastructure that makes it genuinely easy to
build a social life here. For many residents, the community itself becomes as important as the
home.
Who Lives in Trilogy — and Who It’s Right For
Trilogy attracts a specific kind of buyer, and understanding that helps both buyers and sellers.
The typical Trilogy resident is active, social, and financially comfortable. Many are recent
retirees or pre-retirees who sold a larger family home in the Bay Area or East Bay and are
ready to simplify without sacrificing quality of life. They want a beautiful home, low
maintenance, great neighbors, and things to do — without the responsibilities of a big
property.
Trilogy is a great fit if:
You or your partner are 55+ and want a gated, secure, resort-style environment.
You’re downsizing from a larger Brentwood family home and want to stay local.
You value community and social life and want built-in opportunities to connect with
neighbors.
You want single-story living without the compromise of a smaller or lower-quality home.
You’re relocating to the Bay Area to be near family and want a turnkey lifestyle
community.
Trilogy may not be the right fit if you prefer privacy and minimal HOA involvement, have
younger household members who don’t meet the age requirement, or want a larger lot with
more outdoor space.
The Resale Market: What Buyers and Sellers Need to Know
Because Trilogy is fully built out, the dynamics are different from a new construction
community.
Here’s what shapes the resale market:
For Buyers:
Inventory is limited. With no new homes coming to market from the builder, you’re
competing for resales only. When a well-priced, well-maintained home hits the market, it
moves quickly.
Floor plan knowledge matters. With 21 floor plans across six collections, not all square
footage is equal. Some layouts live much larger than others. Working with an agent who
knows the plans — not just the square footage — saves you from making a costly
mistake.
Condition varies significantly. Homes built in 2006 are now nearly 20 years old. Some
sellers have maintained and updated beautifully; others haven’t. Knowing how to evaluate what you’re actually buying is essential.
HOA fees are $478/month. Factor this into your budget. It covers common area
maintenance, amenities access, and community management. For most Trilogy
residents, it’s well worth it.
Average resale prices currently hover around $953,000, with a range from the high
$700s to over $2 million depending on size, condition, location within the community, and upgrades.
For Sellers:
Your buyer pool is specific. You’re marketing to 55+ buyers, many of whom are
downsizing from larger homes and have significant purchasing power. Presentation and
lifestyle marketing matter as much as price.
Condition is paramount. Trilogy buyers are sophisticated and have often toured many
homes in the community. A home that shows wear and deferred maintenance will sit. A
home that is clean, updated, and staged will command a premium.
Pricing requires genuine local knowledge. Because floor plans and orientations vary
so much, you can’t simply pull comps from a radius search and apply them. You need to
compare the right floor plans in the right sections of the community.
Seasonality matters. Trilogy tends to be most active in spring and early fall. Listing at the
right time — not just when it’s convenient — can meaningfully affect your result.
How Trilogy Compares to Summerset
Brentwood’s other major 55+ option is Summerset, which actually comprises four separate
communities (Summerset I, Summerset Palms, Summerset Vista, and Summerset Orchards)
with a combined 2,013 residences and access to an 18-hole golf course. Summerset tends to
offer a lower price point — homes range from the high $400,000s to the low $900,000s — and
a somewhat different lifestyle feel.
The short version: Trilogy is more resort-style and more premium. Summerset is more
established, more golf-oriented, and more accessible at entry-level price points. Many buyers
consider both, and the right choice depends on lifestyle priorities and budget. I work in both
communities and can help you think through the comparison honestly.
Why Work with a Trilogy Specialist?
I want to be straightforward about something: there are agents in Brentwood who will tell you
they know Trilogy because they’ve sold a home or two there. That’s different from having
represented multiple buyers and sellers in the community over several years, knowing which
floor plans have the best flow, which streets get afternoon shade, which updates add value
and which don’t, and what inspectors tend to find in homes of different vintages.
Since 2021, I’ve built real experience in Trilogy. I’ve sat at kitchen tables with sellers trying to
figure out what their home is worth and what it needs. I’ve walked buyers through every
collection and helped them understand what they’re actually getting. I’ve negotiated on both
sides of transactions in this community.
If you’re considering buying or selling in Trilogy at the Vineyards, I’d love to be the first call
you make — not because I’ll tell you what you want to hear, but because I’ll tell you what’s
true.
Let’s Talk.
Whether you’re curious about what your Trilogy home is worth, trying to decide if the
community is right for you, or ready to get started, I’m happy to connect. No pressure, no
obligation — just a real conversation with someone who knows this community well.
