Featured Reviews for ADU Contractors in Janesville

G Chada Design Studio
ADU Contractors in Janesville
Average rating: 5 out of 5 starsMarch 17, 2017
“It's been a while...but no question. Gary was professional, patient, and delivered what he promised and helped a ton when it came to recommendations. (To help us visualize. Needed that help for sure.)”
Precision Design Build Inc
ADU Contractors in Janesville
Average rating: 5 out of 5 starsNovember 1, 2023
“The Precision Design Build team took my hazy ideas and created a lovely, open kitchen that fits our needs for cooking and entertaining. It’s a pleasure spending time in this organized, functional space with such beautiful elements from the earthy cherry cabinets to the modern look of our pendant lights. Thanks, PDB team!”
DePietro Design Associates
ADU Contractors in Janesville
Average rating: 5 out of 5 starsJuly 13, 2016
“As a newcomer to the world of commercial building renovation, we had to rely very heavily on DePietro Design, not only for aesthetic improvements, but bringing the foreclosed property up to 2015 standards and codes as well. We have now been open for a year and had incredible compliments on the design features as well as the functionality of the building. Every aspect of the work was done with a very professional attitude, helpfulness and creativity. I would highly recommend DePietro Design!”
Ruebl Builders LLC
ADU Contractors in Janesville
Average rating: 5 out of 5 starsJanuary 17, 2012
“Ruebl Builders is a fantastic, hands on, detailed custom home builder. Very easy to work with and always accomodating.”
TDS Custom Construction
ADU Contractors in Janesville
Average rating: 5 out of 5 starsMay 31, 2013
“This past fall we completely gutted and remodeled our bathroom with TDS Custom Construction, and had a great experience with them throughout the entire project. We interviewed and received bids from four contractors, and while all of the bids were more or less the same, TDS was by far the most thorough in both their understanding of the project and their project delivery method. I have had on occasion less than ideal experiences with contractors given my line of work (architecture) and was in all honestly hoping for the best but bracing for the worst with this project, but TDS (project manager, lead carpenter, green energy advisor and office manager) and all of their subs were professional, considerate and willing to go the extra mile to make the project a huge success. As much as living through a remodeling project can be challenging, we are looking forward to working with TDS again.”
Ginkgo House Architecture
ADU Contractors in Janesville
Average rating: 5 out of 5 starsSeptember 17, 2012
“Andy at Ginko House is one of the best. His designs are both cutting edge and thoughtful. He is very good at creating space that feels right, and looks great. I've worked with him as a contractor several times, and found him to be a team player, very responsive, yet keeps the integrity of the project at the forefront. His client side manner is excellent. He works very hard to understand what the client is after, and strives to give the client exactly what they need. I reccomend Ginko House Architects very highly.”
Urso Builders
ADU Contractors in Janesville
Average rating: 5 out of 5 starsAugust 30, 2017
“Under budget. On Time. Over quality. This was the third home construction project my wife and I did and by far the best. The Urso team clearly earned our business after interviewing several builders (including some "big name" local builders). What impressed us the most was their honest "open-book" pricing, 100% unique and custom work, and collaboration throughout the build. I strongly encourage you to contact Urso Bros for your next project. I'm confident they'll do an amazing job for you.”
Waterstone
ADU Contractors in Janesville
Average rating: 5 out of 5 starsOctober 24, 2014
“We hired Waterstone to do a complete kitchen remodel and a bump out in our 1898 Queen Anne home. There were all kinds of design challenges here as we wanted to keep the architectural integrity of the house while at the same time end up with a modern high-end kitchen. Michael did a marvelous job. Easy to work with, full of creative ideas and the job was done on the schedule as promised. We are now two years into the kitchen, love it and get all kinds of complements from neighbors and friends. Waterstone does terrific work!”
Maddock Construction Company
ADU Contractors in Janesville
Average rating: 5 out of 5 starsSeptember 16, 2012
“Maddock Construction built our dream home 10 years ago and when our family needed a bit more room we did not hesitate to go to Larry Maddock again for his expert services. We have very particular needs and an eye for detail. Our needs have grown out of our love the Craftsman Period and in particular its realization in the Prairie Style Architecture. Larry and his father before him have prided themselves in bringing the greater Chicago area this genre of homes that was arguably born within its borders. Whether it be detailed trim, woodwork and built-ins or all the components that come together in custom homes to maximize character without blowing a budget you will find no finer custom home builder in greater Chicago and Southern Wisconsin to exceed your dreams. When it comes to an eye for detail, Larry is as impassioned as you will find a builder with the art of home building. This is not a person who lets the details fall to a job supervisor. All of his sub-contractors know him to be extremely attentive to detail and are keenly aware that he will hold them accountable for all of their work as representatives of the quality of his brand. We are always amazed about the frustration and spite that many behold to their builder after a custom home project as our experience could not have been more different. To the contrary, we built a relationship with someone who helped us realize our dreams. If you are a person who dreams about how the ideas of Houzz could come to life in your home, you would be remiss not to talk to Larry Maddock.”
La Muro Associates, Inc.
ADU Contractors in Janesville
Average rating: 5 out of 5 starsJune 20, 2016
“I am an Interior Designer based in New York that worked with La Muro Associates, Inc. We worked on the design and development of a residential home near Madison, Wisconsin. La Muro Associates knowledge, experience and extraordinary design were within budget and on time. His ability to conduct a team of talented professionals in the design and execution of the structure, landscape and interior treatments was outstanding and revealed the skills of an architect with long-standing experience.”

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 Janesville. 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 Janesville: 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.
