Looking for adu construction in Los Altos? ODL Construction is a licensed Bay Area general contractor serving Los Altos and the surrounding Silicon Valley — from Old Los Altos, North Los Altos, South Los Altos 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 Los Altos specifically, it comes down to local realities: Los Altos's large lots and high resale ceiling make whole-home remodels and rebuilds common — the budget supports doing it right, and design review expects exactly that. Los Altos applies design review and floor-area and setback standards on larger projects; the city expects polished, complete submittals. We design and permit your adu construction around exactly those conditions.
