"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."

"Here’s a version of the review tailored for Angie’s List: Amazing Experience with Finish Line Home Services LLC! We had a major issue with a septic backup in our bathroom, and during the cleanup process, asbestos was discovered. Our bathroom was completely destroyed and needed to be rebuilt from the ground up.

Derek took the time to explain all of our options thoroughly, ensuring we felt confident in the decisions we made.

"RT Total Lawn made the process from inquiry to installation easy. Sara responded to my Angie’s request, answered a few questions, then came out with owner Rafael to do an estimate. We discussed drip vs in ground irrigation, agreed on a fair price then the work was scheduled and completed quickly. When done, RT’s crew did a thorough clean up and Rafael and Sara came back to do a walk through. I am 100% satisfied and look forward to working them on other projects. Great to find a local business that does quality work and cares about customer satisfaction. Highly recommend!"

FAQs for addition to existing structure building service projects in Oak Harbor, 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.
