If you’re searching “home remodeling near me” from a Union City address, you’re probably not looking for just one room. Maybe your family has grown, and your 1960s or 1970s tract home no longer fits how you live. Maybe a parent or adult child is moving in, and you need a real plan for the space. Or maybe you’re bundling a kitchen, bathrooms, and flooring into one project instead of doing each separately. We take on all three regularly in Union City.
Every project starts the same way regardless of size. First, we have a phone call to talk through scope and rough budget. Next comes a free assessment at your home, where we walk the whole house with you, not just one room. We put together a written, itemized quote before anything gets signed.
Once you sign off, our team pulls the permit through the City of Union City Building Division. That office sits on Alvarado-Niles Road. From there, we manage design, permits, and construction under one contract instead of handing you off between separate trades.
Most whole home remodels take three to six months to build. Design, plans, and permitting usually add one to three more months before construction starts. Union City’s original tract homes use standard stud frame construction. That’s usually simpler to open up or reconfigure than custom or architect-built homes. A lot of the multiple room work we do here focuses on layout, not structural rebuilds.
Pricing on a whole home remodel depends on five things. Those are overall scope, what’s hiding behind the walls, finish tier, square footage, and permit requirements. Because so many systems are involved, we quote from a detailed walkthrough rather than a flat rate.
Across the East Bay, including Union City, whole home remodels generally run $200 to $500 per square foot. A project on the lower end usually keeps the existing layout and upgrades finishes. A project on the higher end usually moves plumbing or electrical, opens walls, or adds square footage.
We don’t quote a whole home remodel with one flat number. A 1,200 square foot remodel and a 2,000 square foot remodel with an addition are very different jobs.
A lot of our Union City calls aren’t about one room. They’re about bundling a kitchen, one or two bathrooms, and flooring into a single project instead of three separate ones. Bundling saves on permit costs and cuts down on repeat demo and cleanup. It also gets the whole house done on one timeline instead of stretched out over years.
We also handle remodels built around a multigenerational household. That might mean converting a den or bonus room into a bedroom suite for a parent. It could mean adding a bathroom near a downstairs bedroom. Or it could mean reworking the kitchen so two generations can cook at once. If you need fully separate living space instead of a suite within the house, we can help too. Our accessory dwelling unit service covers backyard and garage conversion units for that.
Our office is in Hayward, and we regularly work throughout Union City, including the Old Alvarado and Decoto areas. We also cover Fremont, Castro Valley, and the rest of Alameda County. If you don’t see your address here, ask us. We take on projects throughout the wider Bay Area as scheduling allows.
