California at Home
ADU Contractors in Columbia
Average rating: 5 out of 5 starsSeptember 3, 2014
“Scott designed and drafted plans for a master bedroom extension for us. The plans were submitted and approved by the city with no revisions. That was awesome & a relief! He listened to our desires, took time to answer our questions & responded to all our concerns. He is very knowledgeable about codes & rules. He was efficient & his fees were reasonable. It was a pleasant experience working with him. We are looking forward to having our new addition completed. We would highly recommend California At Home to anyone. Thank you Scott, for the great service! CB”
DMC Construction LLC
ADU Contractors in Columbia
Average rating: 5 out of 5 starsApril 10, 2015
“DMC was a recommendation from our realtor when he realized we wanted to upgrade our new home. It turned out to be the best decision in hiring Donald! We had all flooring, painting, a full remodel of kitchen and also master bath completed on our home within a 6 week period. He started the project on time, kept it on time, answered every question with patience and knowledge, sent us to materials locations that he trusted, had a great staff who had the utmost respect for our home, quality work, fair pricing, rolled with the changes we made along the way, gave great recommendations for design and had every sub imaginable to cover each piece of work we were having done. We even threw a new item in construction his way that he'd never done before, and he came through on that as well. He was ready to tackle anything! I cannot say enough good things about Donald and his staff. This is an exemplary construction company and I would recommend them to anyone, as well as hire them back to do further work on projects we will likely have in the future.”

Anthony Medina Design
ADU Contractors in Columbia
Average rating: 5 out of 5 starsAugust 14, 2017
“Tony was absolutely the best architect! He really took the time to understand our needs, and then he was very responsive through all of the twists and turns as we worked on the designs to figure out the best home for our family. He came up with amazing ideas, and his 3D modeling really helped us to visualize the home. I strongly recommend Tony for any project!”
V-Builders
ADU Contractors in Columbia
Average rating: 5 out of 5 starsJuly 28, 2016
“V-builders refinished my cabinets, tile work, and painting in my kitchen. They also did some work replacing doors, base boards and painting in the rest of my house. They did an excellent job. The estimates were fair and accurate. They were on time, efficient, and had some great ideas to help create the look I wanted. Friendly and easy to work with I would recommend V-builders to everyone.”
Realty Design Associates, Inc.
ADU Contractors in Columbia
Average rating: 5 out of 5 starsSeptember 23, 2017
“We hired Leslie Onsager to take care of designing the interior, exterior, and even landscape of our remodeled home. Words cannot describe the outcome of this craftsman-style home we ended up with! Leslie walked us through every step with professionalism and creativity. She made suggestions when we asked and paid attention to what we liked. When we changed our minds last minute, she gladly worked out the change to our liking! People come into our home weekly and comment on how beautiful and how inviting and comfortable it feels...that's exactly what we were going for! Leslie's tireless efforts to finish the project well and in a timely matter are to commended. I can't recommend this company enough.”

“Ponderosa has worked on multiple jobs for me. Each and every time they finished on time, and on or even under budget, still delivering the best craftsmanship and work done. They are always easy to get a hold of and honest. Cannot thank them enough for the work they have completed. When I need future work to be completed they will be my first call!”

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 Columbia. 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 Columbia: 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.
