I have more than 35 years' of residential, commercial and industrial experience and I pride my company on reliability, great communication, integrity, and quality work. I will do my best to keep you as educated as we can on your particular project. I look forward to earning your business!

"We recently had our bathroom remodeled by Tanoak Construction and we are extremely satisfied with the quality of workmanship. Gant Bowman and Dave Bowman were always available to answer any questions we had and were very transparent throughout the entire process. Finding a local contractor was difficult, but Tanoak Construction made the process easy and stress-free. They were clean, very respectful while in our home, and gave great advice. Every subcontractor they brought in was also great to work with. We highly recommend them to anyone in the Sonoma County area who needs remodeling work done."

FAQs for addition to existing structure building service projects in Santa Rosa, 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.
