Licensed & Insured Owner-Operated Serving the Bay Area

San Jose homeowners know that quality matters. Whether you’re updating a 1950s ranch in Willow Glen, adding space to your Almaden Valley home, or building an ADU in Cambrian, you need a contractor who understands local building codes, neighborhood character, and the high standards Bay Area families expect.

Why San Jose Homeowners Choose O’Maoinagh Construction

Local Expertise: We’ve completed projects across San Jose’s diverse neighborhoods—from the tree-lined streets of Rose Garden to the hillside homes of Silver Creek. We understand what works here.

Permit Navigation: San Jose’s permit process can be complex. We handle all applications, inspections, and coordination with the city so you don’t have to.

Owner Involvement: Brian personally manages every San Jose project. You’ll have direct communication with the owner, not a rotating crew of project managers.
