San Marco is a master-planned community in the southwest hills of Pittsburg, California, built by Discovery Homes and Seeno Homes, offering new-construction homes with Mediterranean architecture, Delta and Mount Diablo views, and quick access to Highway 4 and BART. Recent phases include floor plans from approximately 2,371 to over 4,200 square feet, and Seeno Homes describes San Marco as the largest of its Pittsburg communities.
Why San Marco in Pittsburg Is Worth a Serious Look
I have worked in the East Bay real estate market for over 20 years, and San Marco is one of the most misunderstood communities in Contra Costa County. Buyers hear "Pittsburg" and arrive with assumptions. Then they drive up into the hills, see the rolling terrain, the Delta panoramas, and the red-tiled rooflines, and the picture changes. For the broader picture of the city itself, its neighborhoods, commute, and waterfront, start with my overview of living in Pittsburg, CA.
The appeal is simple. San Marco delivers new construction with four and five bedrooms in a hillside setting with views you do not get in the flatter parts of central and east county. For buyers comparing newer homes across Contra Costa, it offers space, modern layouts, and elevation in one package.
Here is how it comes together.
What You Get When You Buy in San Marco
The Community Layout and Feel
San Marco is not a cookie-cutter subdivision. It is a long-running master-planned community built out in phases, which is part of why it carries a settled, established feel rather than a raw-construction one. Earlier phases include Toscana and Positano, while Siena and Capri are the most recent, and the small Veranda enclave offers a limited number of larger homes on just 13 homesites. Phase availability changes quickly as homes sell, so reach out to me for the current list of available homes and any remaining new-construction inventory.
One local detail that surprises buyers: San Marco sits right at the Pittsburg and Bay Point boundary, and some new-construction homes and listings in the immediate area carry Bay Point addresses rather than Pittsburg ones. Homes practically next door to each other can fall on different sides of the line. That designation can affect your mailing address, school assignment, and property tax line items, so I verify the jurisdiction for the exact homesite before my buyers write an offer.
Homes here are built in a Mediterranean style: brick and stone accents, red-tiled roofing, and arched entries. The streets are wide and the lots support real square footage. The biggest differentiator is elevation. Because San Marco is carved into the southwest hills, many homes look out across the Sacramento-San Joaquin Delta toward Mount Diablo. That kind of view is hard to find in the flatter neighborhoods of Concord or Antioch.
Home Sizes and Floor Plans
Siena at San Marco offers two- and three-story plans from approximately 2,371 to 3,516 square feet, with up to five bedrooms and 3.5 bathrooms. Capri runs approximately 2,380 to 3,415 square feet. The Veranda enclave is larger, approximately 3,441 to 4,257 square feet with up to six bedrooms, on a limited number of homesites.
The value story is about space and newness for the money. Compared to older resale homes in the central county, San Marco gives you newer construction, larger floor plans, and hillside views. For move-up buyers and downsizers alike, that trade can be compelling. If you are still weighing a brand-new home against an existing one, my guide to new construction versus resale in East Contra Costa County walks through how to decide.
A note on pricing: new-construction prices change frequently and published numbers go stale. For current pricing on available homes and phases, contact me for an up-to-date snapshot.
Living in San Marco: The Daily Experience
Commute, Convenience, and Connection
One of the first questions buyers ask is about the commute. San Marco sits just minutes from Highway 4, with BART service nearby at the Pittsburg/Bay Point station for transit commuters. From the freeway, Concord, Pleasant Hill, and Walnut Creek are a short drive. For households that need transit access but do not want to sacrifice home size, that combination is a big part of the draw.
For everyday errands, The Shoppes at San Marco sits at the edge of the community, just blocks from the newest phases. For a fuller range of dining and entertainment, downtown Pittsburg and the Pittsburg Marina are a short drive away, along with the Maya Pittsburg Cinemas for movies.
Schools Serving San Marco
Students in San Marco are served by the Mount Diablo Unified School District, and Delta View Elementary School sits right inside the community, within walking distance for many San Marco homes. One detail I make sure buyers understand upfront: a middle school site has been planned within the community but is not yet built, so middle-school students currently attend other district campuses. School assignments can change, and homes near the Pittsburg and Bay Point line can fall into different attendance areas, so confirm current assignments with Mount Diablo Unified for any specific address before you write an offer.
Parks and Outdoor Recreation
San Marco was designed with the outdoors in mind. The community includes a trail system for walking, jogging, and biking, along with neighborhood green space such as San Marco Hills Park, which offers a playground and open lawn. The hillside setting and proximity to the Delta put recreation right outside the front door.
How San Marco Compares to Other Contra Costa Communities
Buyers weighing options across the county ask me this constantly. Here is my honest read.
Versus Brentwood and Oakley
You get comparable new-construction quality, but San Marco's hillside elevation delivers Delta and mountain views that flat-lot communities cannot match. BART access also tends to be closer from San Marco, which matters for daily commuters. If you are looking at new construction in Brentwood, you will find a different mix of builders, lot styles, and community amenities, just without the elevation.
Versus Walnut Creek and Pleasant Hill
You typically get more square footage for the money, and you trade the walkable downtowns of the central county for newer construction and views. Central county inventory moves fast and competition is fierce, so it comes down to what you value most.
Versus Danville, Lafayette, and Orinda
The Lamorinda and Danville corridor commands a much higher entry point. For buyers who want a newer, spacious home with views and county access, San Marco is an alternative worth comparing seriously.
Who San Marco Is Right For
Move-up buyers who want new construction and modern floor plans without central-county prices.
Downsizers from premium Contra Costa corridors who want to stay in the county near family and amenities.
Bay Area commuters who need BART and Highway 4 access and do not want to give up home size for a shorter drive.
Families who value Delta View Elementary's location inside the community, the trail system, and a true master-planned setting.
I have built my business on giving buyers honest, unfiltered guidance. If San Marco is the right fit, I will tell you. If it is not, I will tell you that too.
Buying New Construction in San Marco: One Thing to Know First
The friendly sales representative in the model home works for the builder, not for you. Their job is to get the best terms for Discovery Homes and Seeno Homes. Bringing your own agent costs you nothing as a buyer, but the builder needs to register your agent on your first visit, so reach out to me before you tour. The process for buying a new build differs from resale in several ways, and my guide to buying new construction step by step walks through the sequence; it is written around Brentwood, but the mechanics apply across East Contra Costa, including San Marco.
