Landscape Service Areas Across Napa, CA and Beyond
Keystone Yards works across three counties, each with its own primary city and surrounding communities. Napa County is the original market and still where most projects happen, but Contra Costa and Marin counties have grown into full markets of their own rather than occasional side trips outside a core service area. Below is the full breakdown by county, with a page for each city linked so you can see local details specific to where you live.
Napa County
From hillside vineyard properties in Rutherford and St. Helena to in-town lots in Napa itself, this county covers a wide range of terrain, and Owen accounts for that variation on every site visit rather than treating one part of the county like the rest.
Contra Costa County
Walnut Creek anchors this county, and lots here tend to be flatter and more suburban than what's typical further north, which changes what a design and build project usually looks like even though the same team and process apply.
Marin County
San Rafael anchors this county, which covers the largest number of individual cities of the three. Properties here often deal with coastal fog and different planting conditions than the drier, hotter climate found elsewhere in the service area.
If your city isn't listed here, it's worth a call, service areas sometimes extend slightly beyond what's listed, and our team can tell you directly whether your address is covered rather than assuming based on a zip code alone.
What Stays the Same in Every City Keystone Yards Serves
Location changes the terrain, the climate, and the specifics of a project, but it doesn't change how Keystone Yards operates. Here's what stays consistent no matter which of the cities your property falls in:
Homeowners Across Three Counties Trust Keystone Yards
Keystone Yards holds five-star ratings on Google, Yelp, and Facebook, along with Better Business Bureau accreditation and a Houzz profile. That reputation isn't limited to one city, it's built from projects across Napa, Contra Costa, and Marin counties alike, so the trust signals you see here reflect the whole service area, not just the home market.
Our Guarantee, Every City
Every project across all 29 cities Keystone Yards serves is backed by our workmanship guarantee, in writing. Location doesn't change the coverage, a project in Novato is backed the same way as one in Napa.
If an issue comes up, the process is the same regardless of which city the project is in: you call, describe the problem, and our team schedules a time to come take a look. There's no separate process for homeowners further from Napa, and no reduced coverage for cities at the edge of the service area.
Building Across Three Very Different Counties
A hillside property in St. Helena, a flat suburban lot in Walnut Creek, and a coastal-influenced yard in Marin County all call for different design and construction decisions. Keystone Yards treats each property according to its actual terrain, soil, and climate, rather than applying one regional approach across three counties that don't behave the same way.
That local knowledge shows up in specifics: drainage plans that account for hillside grading in Napa County's wine country towns, planting choices suited to Marin's cooler, foggier microclimates, and material selections that hold up under Contra Costa's hotter inland summers. None of that comes from a generic playbook, it comes from actually building across all three counties on a regular basis.
