Looking for adu construction in Palo Alto? ODL Construction is a licensed Bay Area general contractor serving Palo Alto and the surrounding Silicon Valley — from Professorville, Crescent Park, Old Palo Alto 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, house family with independence, and — under California's new AB 1033 — even be sold separately like a condo where your city adopts it.
For Palo Alto specifically, it comes down to local realities: Palo Alto's planning department is famously rigorous — Eichler single-story overlays, individual-review neighborhoods, and historic resources mean the design package matters as much as the build quality. Palo Alto runs one of the most thorough planning processes in the region — design review, historic resource considerations, and Eichler overlays add time. We design to those rules up front so the project clears review without redesigns. We design and permit your adu construction around exactly those conditions.
