Featured Reviews for ADU Contractors in Washington

Creative Eye Design + Build, LEED AP
ADU Contractors in Washington
Average rating: 5 out of 5 starsMarch 10, 2013
“I hired CEDB to do a complete remodel on my kitchen. I have nothing but high marks to say about Susan. She is excellent in her communication; very prompt. She is very capable to handle all the decisions for a project if that's what someone wanted but she is also happy to collaborate and incorporate the owner's ideas. She has a great rapport with the sub-contractors and works with them often which results in high quality work in a timely manner and the finish work actually gets completed! Compared to when I acted as the contractor for a previous kitchen remodel i can say that hiring CEDB made it so much easier.”

Average rating: 5 out of 5 starsMay 31, 2017
“We are in the process of renovating a 100 year old SF Edwardian and started on the upstairs rooms. After interviewing and meeting with several contractors we chose Lee & Co. and couldn't be happier. From start to finish, this was an excellent experience. We are still amazed at how meticulous, professional and hard working everyone was and the fact that the project was finished on time-incredible! We want to thank Rob for the personal attention he gave our project and for the outstanding level of communication. We are truly impressed with the results and look forward to continuing our relationship when we get to the downstairs project.”

“My wife and I hired GXDB to build an addition onto our family home in East Sacramento, to support a new Master Bedroom. We interviewed other companies, but were just more impressed with GXDB. We were very happy with the process and more importantly, the finished product. GXDB stayed on schedule, on budget and far exceeded expectations. We'd recommend them to our friends and family without hesitation.”

“Jim did a fabulous job installing a glass and steel door for us. It is still perfectly balanced 2 years later. He is responsive, answers his phone and has a fair price. I would definitely recommend him and use him again.”
RIEK Builds, Inc.
ADU Contractors in Washington
Average rating: 5 out of 5 starsOctober 14, 2015
“The Rieks did a great job with a total gut and rebuild of our 1200 s.f. 3BR 2BA condo in Incline Village. They helped us from the start with a vision of a revised floor plan and also made themselves available to help us choose materials that met our design vision at a reasonable cost. They also handled all of the interaction with the condo association. The work itself was done at top quality levels despite the labor challenges in the Tahoe area and we have received many compliments from friends and family in the construction industry about the quality of the work. The punch list of follow up items was handled promptly and efficiently. The project came in near the estimated budget cost and we have been very happy with our new condo.”

An accessory dwelling unit (ADU) is a separate living space that can be added to your property. It functions as an additional dwelling on the same land where your main home is located. ADUs have their own amenities and entrance, providing a self-contained living area. Unlike a traditional home, an ADU cannot be sold separately and is considered part of the same property.

ADUs are subject to specific zoning regulations and building codes in Washington. These regulations determine where and how an ADU can be constructed, ensuring compliance with local laws and requirements. It’s important to consult with local authorities or a professional contractor who is familiar with ADU regulations in your area to understand the specific legal differences and ensure your ADU meets all necessary criteria.

Consider these options for cost-effective ADU:
  1. Prefabricated ADUs: Affordable and easy to assemble, they’re a practical choice. Many prefab ADUs cost under $100,000.
  2. Traditional Construction: Work with an ADU contractor to find budget-friendly options and make smart choices.
Tips for cost-effective ADU construction:
  1. Define your needs: Determine the purpose of your ADU, whether it’s for family, rental income, or a home office.
  2. Consult a contractor in Washington: Their expertise can help with cost-effective materials, designs, and planning.
  3. Prefabricated components: Consider using prefabricated elements like cabinets or bathroom fixtures to save time and money.
  4. Explore financing options: Look for ADU-specific loans or programs to help cover costs.
Ensure compliance with local regulations and seek professional advice. A knowledgeable contractor can make the process smoother and cost-effective.
