Looking for home additions in Union City? ODL Construction is a licensed Bay Area general contractor serving Union City and the surrounding East Bay — from Decoto, Alvarado, New Park 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 Union City specifically, it comes down to local realities: Union City's value-oriented family market makes ADUs, garage conversions, and bedroom additions the projects with the strongest payoff per dollar. Union City supports ADUs and additions with a straightforward permit process; regular tract lots keep design and construction efficient. 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.
