Looking for adu construction in Redwood City? ODL Construction is a licensed Bay Area general contractor serving Redwood City and the surrounding Peninsula — from Emerald Hills, Mount Carmel, Friendly Acres 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 Redwood City specifically, it comes down to local realities: Redwood City is more ADU- and growth-friendly than its pricier Peninsula neighbors, which makes additions and second units especially attractive on its varied lots. Redwood City is among the more accommodating Peninsula jurisdictions for ADUs and additions; permitting moves reasonably with a complete submittal. We design and permit your adu construction around exactly those conditions.
