Featured Reviews for ADU Contractors in Portland

JCS Construction LLC
ADU Contractors in Portland
Average rating: 5 out of 5 starsMay 4, 2023
“First let me say I grew up in a family of union carpenters, and can without a doubt Caleb with JCS Construction is a master of his trade. He doesn't cut corners and if your lucky enough to have him build for you all of the other tradesmen will thank you. I have seen a lot of junk built over the years a Caleb just won't do it he takes pride in his work and is super good at it. He framed and dried in a 3400 sq foot house for me in 7 weeks that I needed done by winter and did so the right way. True craftsmanship by a true Craftsman. I get compliments on Calebs work all of the time use him you won't regret it.”
Terry Wilson Construction LLC
ADU Contractors in Portland
Average rating: 5 out of 5 starsOctober 5, 2018
“Terry did an upgrade on my kitchen, new electrical, cabinets, counter top and floor. We were so pleased, we had him remodel our basement, including a tv room, new flooring and lighting. He's professional, dependable and has great remodeling ideas.”
Mountainwood Homes
ADU Contractors in Portland
Average rating: 5 out of 5 starsSeptember 21, 2012
“Mountainwood Homes performed magic on our 1986 galley kitchen. On Joel's first visit, he saw what the other contractors missed: what we thought was a bearing wall was only holding up the balcony. Reducing the size of this underused space allowed expansion of the kitchen below and removal of an unnecessary hallway. The dated drop ceiling and recessed light panel were replaced with a vaulted ceiling and hanging track lighting. Even though the original attic space above the range had access to the roof, the hood was not vented. The old electric range had a downdraft that never worked well and a small oven. The new kitchen sports an island gas cooktop, overhead vent with a chimney extending up through the vaulted ceiling, and a 30" wall convection oven. Heather provided great design with granite, backsplash, paint, and fixtures. Cabinetry by Cutting Edge was a perfect fit. We also extended the hardwood flooring into the dining room. The Mountainwood team was flexible as changes were needed, finished the project on time and produced great results.”

Rebuild
ADU Contractors in Portland
Average rating: 5 out of 5 starsMay 13, 2013
“I have known and worked with Todd Hertner for close to twenty years. First when he was THE go to contractor in the tile and surfaces industry and now when I need Rebuild's skills in making a project look its absolute best. Todd's professionalism and Rebuild's level of perfection and pricing have put them in first place on my cell phone rolodex! I can not recommend Todd Hertner and his company Rebuild LLC highly enough!”

Woodland Construction Group LLC
ADU Contractors in Portland
Average rating: 5 out of 5 starsMay 3, 2023
“I recently had my kitchen remodeled by Woodland Construction Group in Portland, Oregon. I am so thrilled with the results! They were able to take my outdated kitchen and transform it into a beautiful, functional space that has completely reimagined my living experience. I especially love the new kitchen cabinets, countertops, and backsplash, which give the space a modern and fresh look. I can not believe how great everything looks! The upgraded lighting they chose made a huge difference as well. This was one change that I did not realize would make such a big improvement to our kitchen. I am glad I listened to their advice on this one. I get so many compliments from my family on the pendant lights over the island. One of the best parts about working with Woodland Construction Group was their ability to listen to my needs and wants while staying within my budget. Overall, I highly recommend Woodland Construction Group for anyone looking to remodel their kitchen or undertake any other renovation projects in the Portland area. Their expertise, the fact that they listened to us the entire way, and their ability to deliver exceptional results make them standout choices in the kitchen remodeling industry.”

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.
