Looking for home additions 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. Room additions, primary suites, and second stories that look original to the home.
In a market where moving up costs hundreds of thousands in transaction costs and a bigger mortgage, adding on is often the smarter play — especially in top-school neighborhoods where the right addition returns more than a relocation. The key is an addition that looks like it was always there, not bolted on.
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 home additions around exactly those conditions.

Home Additions cost
Typical Bay Area ranges, not a quote. Additions price by square footage, structural complexity, and foundation work. Second stories cost more because the floor below must be reinforced. You get a fixed proposal after design.
