They don’t start working unless they have all the materials which makes the renovation go by fast. Very clean and courteous people. I will be using them in my future projects."

"Eric and his EA Homebuilders team remodeled our primary bathroom, which involved moving walls, framing, plumbing, electrical, installing a tile shower, and finishes. I had never worked with them before. Their quote was competitive, their work progressed at a rapid pace, and they finished the project in the timeframe promised. There were 2 occasions where changes needed to be made and they were reasonably accommodated without any nickel-and-diming. Eric is a great communicator and is always asking the customer if they need anything. Working with a contractor for the first time is always a nervous experience, but EA Homebuilders delivered on everything, and they will be invited to bid on all of my future projects."

FAQs for addition to existing structure building service projects in Oakley, CA

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
