Home Additions in San Jose
Room additions and second stories that look like they were always there.
Trusted home additions for San Jose homeowners
When San Jose homeowners need home additions, they call VDC Construction. San Jose's older Willow Glen and Rose Garden homes are prime for kitchen, bath, and whole-home updates, while Almaden and Cambrian's larger lots are made for additions and ADUs. We know the city's permitting and build across all of it.
The mark of a great addition is that nobody can find the seam. We match rooflines, siding, stucco texture, and window styles to your existing home, and we handle the structural engineering, foundation work, and Title 24 energy compliance that additions in California actually require.
Primary suites, family rooms, home offices, and second-story additions — from design and permits through the final coat of paint, one accountable team.
We work throughout San Jose — from Willow Glen, Rose Garden, Almaden Valley, Cambrian Park, Naglee Park to the homes near Santana Row and Downtown San Jose. Because we've served Santa Clara County for over 11 years, we know the area's homes, common system types, and what San Jose's climate demands of them.
