Local Knowledge

Remodeling Tumwater homes

Tumwater blends established 1960s-80s neighborhoods near the historic brewery district with newer development off Littlerock Road. Primary bathroom renovations and kitchen refreshes lead the project list here, and Thurston County scheduling pairs well with our Olympia and Lacey work.

Permits: the City of Tumwater Community Development Department issues residential permits. We handle the entire permit process, applications, plan documents, and inspection scheduling, on every project.

We had our patio converted into a sunroom at the end of 2025 and are pleased with the outcome. DA Interior Solutions did an outstanding job from start to finish. Their craftsmanship is top-notch, they used premium materials throughout, and they were incredibly attentive to every detail from inception to completion. The entire renovation was smooth and hassle-free. Devon and his team were professional, communicative, and clearly took pride in their work. The carpentry they did on our home is exceptional-you can tell they are about quality. We highly recommend DA Interior Solutions to anyone looking for a reliable, skilled team for their next home project. Thank-you Devon and crew!

Budget & Planning

What to expect on cost

Conversions are one of the best value-per-square-foot projects in a home because the shell already exists. Cost is driven by moisture control, whether you are adding a bathroom, and egress requirements. We assess all three on a walkthrough and price it clearly.

Q & A

Questions, answered straight

Can I add a bedroom in my basement legally?

Yes, with proper egress. A legal basement bedroom needs a compliant egress window or door for safe exit, plus the right ceiling height and ventilation. We handle the egress work and the permit so the room counts as legal living space, not just finished square footage.

Will my basement stay dry after it is finished?

That is the first thing we solve. Before any framing, we address moisture: grading, drainage, vapor barriers, and waterproofing as needed. Finishing over a wet basement is the most common mistake we get called to fix, so we do it right from the start.

Can a garage conversion be an ADU I rent out?

In many cases, yes. A garage conversion can become a legal ADU with the right permits, egress, and utility connections, which we manage. We confirm what your lot and jurisdiction allow before you commit.

Which Tumwater neighborhoods do you serve?

All of Tumwater, including Tumwater Hill, Brewery District area, Littlerock corridor, plus the surrounding Thurston County area. We're about 40 minutes from our shop.
