TBrothers Renovations
ADU Contractors in Lewiston
Average rating: 5 out of 5 starsApril 2, 2020
“We have been working with the T-Brothers who have gutted and renovated our 1950s ranch house, workshop, garage, and constructed a large addition. We have found the T-Brothers and their crew to be highly reliable with honest pricing. We have been very impressed with their high-quality workmanship, their work ethic, and their attention to detail. They have been timely, easy to work with, responsive to our concerns, and have provided knowledgeable guidance about materials and subcontractors that have enabled us to make good decisions. Based on our experience, we highly recommend that you get in touch with the T-Brothers and see what they can do for you.”
The Home Improvement Services

Average rating: 5 out of 5 starsDecember 21, 2022
“Patricio was an amazing contractor to work with. We did a full house renovation this past summer. one Kitchen, two bathrooms, Engineering Floor in the whole house, Interior Garage Floor and exterior interlocking, wood deck in the backyard plus many other details and spaces. Patricio and his crew were courteous, kept us informed about options and pricing, provided creative solutions to maintain us in budget and kept to the timeline for the job. From start to finish they listened to our concerns and were right in line with the look and design of the new spaces we wanted. The price was right and I feel we got a lot more than any other company would have done. This was no a small job with multiple unforeseeable issues that were resolved by Patricio to the last detail providing my family with peace of mind on all the options we choose. This is clearly a company that has integrity in their work and cares about their customers needs, something that is difficult to find these days . I will definitely use them for future renovations and recommend them to my friends.”

Bespoke Contracting
ADU Contractors in Lewiston
Average rating: 5 out of 5 starsJuly 24, 2021
“I have used Bespoke over several years starting with small projects which lead to larger ones such as a basement and kitchen reno. Andrew has great background knowledge, good contacts and a hardworking crew. He reacted quickly to an emergency flood in our basement while we were out of town which prevented further damage. He is easy to reach for any questions or concerns. A bonus is that his wife is in design so he understands that part of a project as well.”

BLDG Workshop Inc.
ADU Contractors in Lewiston
Average rating: 5 out of 5 starsAugust 7, 2013
“We can highly recommend BLDG Workshop with complete confidence. In contrast to the many bumps along the way of our renovation and addition, the design process was exciting and enjoyable. Nathan and his team of professionals were timely and efficient, good at communication, and willing to work with the trades we had hired; however, their best attribute is of course their smart, inspired design! Our favourite part of working with BLDG was the collaborating... they are the experts but they listened to our ideas and were excellent at incorporating our whims and wishes. We will definitely be contacting BLDG the next time we build!”

“We hired Aaron and his team to build our home in Ashburn a few years ago. We called them back to renovate our studio and we are very pleased with the outcome. Having such a great team build your family home and your business is truly a blessing. We are very thankful.”
EZDimensions - Home Renovation Design to Permits
ADU Contractors in Lewiston
Average rating: 5 out of 5 starsDecember 22, 2014
“We hired Erin back in spring 2012 for our Home Renovation and it was one of the better decisions we made. Our home was built in 1920 and our addition required a well thought out design which Erin was able to deliver and help walk us through. Erin exceeded our expectations from her initial visit to discuss what we were looking for in our addition, right through to the final drawings completion and permit delivery.”

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 Lewiston. 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 Lewiston: 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.
