"Platinum General Construction LLC was contacted after two initially hired contractors were incompetent in providing the remodeling services needed for our bathroom remodel in Dec/Jan 2025. Platinum stepped in and completed the work on time and as quoted. David was our primary contact. He was great as respects communication, working through issues, and coordinating with subcontractors. The remodel included heated tile floors, a curbless shower, toilet install, and beautiful tile work. We were pleased that Platinum got our project back on track and finished after dealing with the mis-steps of our original contractors."

"Rob and Aiden helped us with the build out of a rental unit. The amount of work that they did in one week was far beyond what we had anticipated they would be able to accomplish, and would have taken us 5-6 weeks on our own, at least. We're so grateful for the work they did for us as it alleviated a lot of stress and their quality of work is great."

FAQs for addition to existing structure building service projects in Mount Vernon, WA

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.
