Built by Krueger
ADU Contractors in Thornton
Average rating: 5 out of 5 starsFebruary 9, 2016
“It is clear to all of us here at Green Landscape Solutions, that Built By Krueger is one of the best general contractors in the Boulder County area. We’ve had a strong business relationship with this company for several years. During that time we’ve found that Kruegers excel at communicating with their clients and subcontractors. They outclass their competition by a wide margin; by paying attention, providing an excellent value for their work, and demonstrating a commitment to providing the best customer service.”
FTC - Final Touch Construction of Colorado
ADU Contractors in Thornton
Average rating: 5 out of 5 starsJanuary 24, 2017
“After 15 years of dreaming and speaking with seven contractors over several months, we decided to use Final Touch Construction for a significant remodel of the main floor of our home and have not regretted the decision. My original dream was beyond our budget, but Glen encouraged us to consider options that would incorporate the aspects that were most important. After lengthy conversations, he offered three designs that addressed our budget limitations, included nearly everything that was part of the original vision and, once we made a selection, he was willing to integrate sensible suggestions from us. During construction, we were going to live in the basement with two large dogs so staying on a timeline was a very important measure. Glen estimated 4-5 months and we were moving back upstairs in 4 ½ months! Their crews were considerate and efficient, and diligently cleaned up each day, which given the fact that more than half of the main floor was gutted and reconfigured was amazing. I would recommend Final Touch for your remodel projects without hesitation.”
Natural Construction
ADU Contractors in Thornton
Average rating: 5 out of 5 starsJune 11, 2013
“Natural Woodworkers completed a full remodel of our home including exterior and interior elements. We enthusiastically recommend them! They gave us a new kitchen, bathrooms, hardwood floors, tile work, custom cabinets and all the details perfectly done to my wife's quite exacting standards. Let me also mention the pergola, siding and important fixes our 40 year old home needed. Now our home is like new. The former owner drove by one day and begged us to give him a tour. He was so impressed that he pleaded to have us show it to his wife later that day! Aside from the excellent work these craftsmen do, you will find they are just plain great people. We actually missed them when they were finished. I whole heartedly recommend these guys. Come see my place if you think I'm exaggerating.”
Story Renovations
ADU Contractors in Thornton
Average rating: 5 out of 5 starsFebruary 2, 2023
“We have a wonderful 1950s custom ranch home. We have lived in our home for over 30 years and this time decided to really do it all- down to the studs, all new bathrooms and kitchen! The craftsman ship and attention to detail have been outstanding. Every trade that worked on our home was a true professional. Additionally, Story Renovations has been absolutely outstanding with follow-ups to the items that needed attention following our move in. We couldn't be happier with our "new" home! My husband and I were just commenting the other night how pleased we are and we are so glad we chose Story Renovations.”
Seawolf Development
ADU Contractors in Thornton
Average rating: 5 out of 5 starsFebruary 1, 2022
“Bryan has done some exterior work on our 1930s house that I couldn't find anyone else who would even consider the job. His team was quick, efficient, and friendly. We enjoyed the experience so much that we had him do a full kitchen remodel. The kitchen project was affected by covid and supply chain issues, so we had some delays and had to make some different choices due to price fluctuations, but Bryan was very communicative and honest during the process. He and his team find ways to get things done rather than take the easy way out or make excuses. The kitchen is beautiful and functional. I strongly recommend Seawolf and Bryan for any interior or exterior work you might be considering.”
Savignon Interiors
ADU Contractors in Thornton
Average rating: 5 out of 5 starsAugust 3, 2015
“Gabriela went way beyond the call of duty to help my husband and I pull together the remodel/interior design of my home in 2 months. I had a contractor but we needed help to choose tile, paint, draperies, faucets, tub, lighting fixtures and more. She also gave us contact information to find a great electrician to install new lighting fixtures - sconces, chandeliers, and many recessed lights to brighten up a dark home. We met at stores and showrooms. Gabriela met our deadline, gave us suggestions but is a great listener and always supported our decisions.”
Factor Design Build
ADU Contractors in Thornton

“Factor Design Build is the type of reputable company that makes things happen. In the world of construction, there are always challenges and deadlines. This team of professionals has a great ability of pulling together their resources to take action quickly. They take problems and turn them into opportunities that work well for the construction team, design team and home owner. I will continue to work with this team as they create beautiful, thoughtful and creative design projects.”

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 Thornton. 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 Thornton: 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.
