Featured Reviews for ADU Contractors in Portland

Bigfoot Northwest
ADU Contractors in Portland
Average rating: 5 out of 5 starsOctober 28, 2019
“I almost missed the opportunity to work with Bigfoot Northwest. I had already verbally agreed to a bid to remodel and convert my garage but a little voice said to get another bid. Bigfoot NW responded right away and owner/partner Austin came out. He did a thorough walk through, listened to all my ideas and concerns and gave me a very honest straight forward answer. While what I wanted to do was possible, it was not gonna be easy or the most financially fruitful. He then purposed a totally radical idea that completely blew me outta the water. It meant at least a 3/4 cut in bid price for his company but it was the creative and beneficial idea for me financially. Tear down my existing dilapidated garage and get a tiny house instead for half of what it would cost me to rebuild. Friggin genius! Bigfoot would do the demo, and prepare the site, and help me with the hookup. He then gave me a list of tiny house builders with great prices and helped me plan out the set up. I had previously spoken to 4 other contractors up until that point with bids into six-figures, some didn’t even bother to actually take the time to come meet me or do a walk through. I said ADU and they threw me a price. Bigfoot not only took the time to partner with me on this project but Austin and his owner partner Adam, who did most of the demolition, invested their time and experience in helping me build my financial future. I feel very fortunate to know them, they’re top notch fellows and I can’t recommend them enough!!”

“Nate worked on our kitchen / laundry room / guest bath remodel in 2020. In 2022, we hired him to replace our deck and installed new railings. In 2023, we needed to replace windows on our beach house he was the only person we contacted. His workmanship and attention to detail is incredible. We like working with him as he meets his commitments and communicates throughout the entire project. He also offers up suggestions and ideas and is a pleasure to work with.

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 Portland. 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 Portland: 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.
