Looking for adu construction in Sunnyvale? ODL Construction is a licensed Bay Area general contractor serving Sunnyvale and the surrounding Silicon Valley — from Birdland, Cherry Chase, Heritage District 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 Sunnyvale specifically, it comes down to local realities: Sunnyvale's Eichler and ranch stock demands a contractor who understands post-and-beam construction, radiant slabs, and the single-story overlays that protect some of these tracts. Sunnyvale supports ADUs actively, but several Eichler tracts carry single-story overlays that restrict second stories — we confirm your zoning before designing up. We design and permit your adu construction around exactly those conditions.
