"I'm not joshing you, but Josh Powers was great. We had a ton of questions and he answered them in a fast manner. Great work, high-quality and no complaints. He was patient when I drove back to get him assistance on his end on a Friday afternoon. I'd recommend him to anyone in Central Ohio for handyman duties, electrical, carpenter work, and, especially painting. He did a great job with painting three rooms and a kitchen--everything is top-notch!"

"Ohio Exteriors completed a three-season room that met all of our expectations.

The crew paid attention to details and adjusted well to the challenges that popped up along the way. The work was completed in a timely manner, and the site was kept clean throughout the project."

FAQs for addition to existing structure building service projects in Westerville, OH

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.
