San Marco sits in the eastern half of Pittsburg's 94565 — a 347-home master-planned community with multiple active phases from Seeno Homes (Siena at San Marco, Veranda) and Discovery Homes (Capri at San Marco). Neighborhood parks, planned amenities, and one of the more polished new-home experiences in the corridor.
New-construction pricing in San Marco has stepped up sharply — current Capri at San Marco (Discovery Homes) and Siena at San Marco (Seeno) phases list $970K to $1.099M+ for 2,380–3,415 sqft floorplans. Established 2000s–2010s resale stock in the wider San Marco footprint trades roughly $660K–$780K, which is where many of my first-time buyers land.
The community has planned parks (Bay Point Regional, Sand Creek Open Space nearby), a Safeway-anchored shopping center, and a feel that's quieter than older Pittsburg. Worth walking at different times of day — I do this with every buyer.
Schools are Pittsburg Unified throughout — a mixed district with specific strong elementaries (Stoneman, Heights, Willow Cove) and a growing Pittsburg High. I pull the specific feeder for any address before we tour.
