Looking for adu construction in Santa Clara? ODL Construction is a licensed Bay Area general contractor serving Santa Clara and the surrounding Silicon Valley — from Old Quad, Forest Park, Rivermark and beyond. Detached, attached, and garage-conversion ADUs — rental income and family space, fully permitted.
Accessory Dwelling Units are the single best way to add value, income, or multigenerational space to a Bay Area property — and California's pro-ADU laws have made them faster to approve than almost any other project. A well-built ADU can rent for thousands a month or keep family close with independence.
For Santa Clara specifically, it comes down to local realities: Santa Clara is our headquarters city — flat ranch lots near major tech employers make it one of the strongest ADU and addition markets in the valley, and our crews are minutes away. Santa Clara's building department is straightforward and accessible — a manageable jurisdiction for additions and ADUs when drawings are complete and code-current. We design and permit your adu construction around exactly those conditions.
