“Buck The Builder got the job done at our house. There were some bad weather challenges that slowed the process, but Buck and a helper pushed through the cold and rain and got it done. These are people that I have trusted for many years and will continue to as the need arises.”

Brickmoon Design
ADU Contractors in Washington
Average rating: 5 out of 5 starsJanuary 31, 2013
“We hired Brickmoon Design to draw plans for our small 1920 bungalow to add a 2nd bath and were hoping to get the washer/dryer into the house (from the garage). They came up with 2 main ideas, took dimensions and we had the survey done, but we have not made a decision on whether to 1) stay within our small 1350 sf footprint, or 2) add onto the house at a substantially higher cost. My husband doesn't want to spend the extra money to add on but I like the addition idea the best, so we have not gone any further. So far, we are out about $5,000 for plans and survey but are stalled. Brickmoon gave us exactly what we asked for, but I still think there has got to be a cost effective way to add an additional 200-300 square feet. Am I dreaming?”
T.G. I. Vaughn, Architect
ADU Contractors in Washington
Average rating: 5 out of 5 starsOctober 28, 2015
“If there were an option for 6 stars for those rare experiences that deserved it, I would give it to Tad without hesitation. Tad was the dream architect and exceeded our expectations! He did things QUICKLY, was always in excellent communication, changed things without ever a single complaint, and was absolutely perfect. If you are building in the Bryan/ College Station area, I would recommend him without hesitation.”

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.
