"Cal Patton is THE ABSOLUTE BEST. The work he did remodeling my garage into a studio apartment was done with quality workmanship, professional care, and great communication. Now, two years later, I am adding a bathroom and had some questions. Cal answered my texts and calls immediately and, even though he had several other projects going on, he literally jumped in the car and came to advise another contractor to set him straight. (I wish Cal could be doing the bathroom addition but he was booked currently.) I highly recommend Cal. He's got your back, he is a true pro, and a great human being."

FAQs for addition to existing structure building service projects in Suisun City, 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.
