The Builder
Castle Companies · Homebuilders with Solid Roots

Founded in 1966, Castle Companies began as a family passionate of home building dedicated to crafting homes of exceptional quality and enduring design. Over five decades later and still family-owned and operated, that same level of commitment remains at the heart of everything they do. While keeping a finger on the pulse of how you think, feel, and live, they have not only grown in strength, but have evolved alongside generations of Northern Californians who continue to look to them for homes defined by innovation, craftsmanship, and enduring excellence.

Blending tradition with innovation, Castle Companies has become one of Northern California’s most respected homebuilders, known for creating distinctive residences of superior craftsmanship and for being a trusted, community-minded neighbor.

While their projects continue to evolve, one value never changes: they build with integrity, purpose, and pride, honoring the legacy that began more than 50 years ago.
