Scope of Work

What a DuPont home additions includes

Every remodel is scoped to your home, your written estimate lists exactly what's included. A sample of what we cover:

▸Room additions and bump-outs: primary suites, family rooms, home offices, and kitchens
▸Accessory dwelling units (ADUs): attached, detached, and garage conversions for rental income or multigenerational living
▸Second-story additions and structural reconfiguration
▸Foundation, framing, roofing, and exterior tie-ins matched to the existing home
▸Full mechanical scope: electrical, plumbing, and HVAC extended to the new space
▸Design, engineering, and permitting handled for you
▸Finishes matched to the existing home so the addition never looks bolted on
▸Built to current code and energy requirements

Additions and ADUs typically run two to four months depending on size, foundation work, and permitting timelines, which we manage and keep you ahead of.

Local Knowledge

Remodeling DuPont homes

DuPont is a master-planned community anchored by Northwest Landing, a tightly built stretch of late-1990s and 2000s craftsman-style homes. With so much of the stock the same age, the common jobs are first-round kitchen and bath updates and finishing the bonus and basement spaces builders left open.

Permits: the City of DuPont issues residential remodel permits through its Building division. We handle the entire permit process, applications, plan documents, and inspection scheduling, on every project.

Field Reports

What clients say when the dust settles

★★★★★

DA Interior Solutions handled our kitchen remodel start to finish, they even created a custom pantry for me. They brought my Pinterest board vision to life. Adam and Devon were great to work with. If you're remodeling in the South Sound, these are the guys to call.

DA Interiors exceeded our expectations PERIOD. Don't let their youthful appearance fool you, they are hardworking, diligent, honest, skilled and respectful. Our three bathrooms were demolished and transformed into a beautiful work of art.

★★★★★

DA Interior Solutions redesigned two bathrooms for us and completed a kitchen remodel. We couldn't be happier with the results. They were a pleasure to work with, often going above and beyond expectations. On budget and on time, we would love to work with them again on any future projects.

Budget & Planning

What to expect on cost

Additions and ADUs are priced by square footage, foundation and structural scope, and finish level. We walk the project with you, flag the cost drivers like foundation, roof tie-in, and utility runs up front, and give you a clear line-item estimate, including the rental-income math if an ADU is the goal.

Q & A

Questions, answered straight

Is an ADU worth it for rental income?

Often, yes, especially in our market, where demand for rentals and multigenerational space is high. We give you a realistic build cost and timeline so you can run the numbers, and we handle the permitting that makes an ADU legal to rent.

Will the addition match my existing home?

That is the whole point. We match rooflines, siding, trim, and finishes so the addition reads as part of the original home, not an obvious add-on. Done right, you cannot tell where the old house ends and the new space begins.

Do you handle the engineering and permits?

Yes. Additions involve structural engineering and a fuller permit set than a remodel, and we manage all of it, design, engineering, plan submittal, and inspections, so you are not chasing architects and the city yourself.

Which DuPont neighborhoods do you serve?

All of DuPont, including Northwest Landing, Hoffman Hill, Palisade, Bell Hill, plus the surrounding Pierce County area. We're about 30 minutes from our shop.

Who handles remodel permits in DuPont?
