Featured Reviews for ADU Contractors in Keystone

Natural Construction
ADU Contractors in Keystone
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.”

TKP Architects
ADU Contractors in Keystone
Average rating: 5 out of 5 starsNovember 18, 2013
“The architects at TKP have great vision and practical ideas. I had spent months working with another architect to design an addition to our 55-year-old home but nothing clicked. Then Karen Keating looked all through our home, sat down and in a matter of minutes roughly sketched out a plan which included a dining nook, den, office, bath and storage room. I knew we'd found the firm with which we wanted to work. Everyone that we worked with at TKP was respectful of our ideas, and then made them even better. We love our three-year-old, 1000 square foot "new" space. It flows beautifully with the original house.”
Forward Architecture, LLC.
ADU Contractors in Keystone
Average rating: 5 out of 5 starsJuly 24, 2020
“I pretty much knew want I wanted to do with my project. I warned Ellen I knew enough about architecture to be dangerous. Ellen recognized my requirements and was instrumental in identifying other considerations needed for the project. Included was a need for a code variance (setback). I was informed by the city, before starting the project, a code allowance(variance) was not required. Ellen’s code research was right. A code allowance was required. With her help, the review board approved the code allowance request unanimously. Our project involves bumping the attached garage eight feet to allow for a utility room between the garage and house. The design includes moving the washer and dryer out of the basement. As simple as the project sounds, there is a lot involved. Ellen listened to my wife’s concerns and ideas on the project. Together we achieved a very efficient design. We are now in the permit and construction phase of the project. I am looking forward to Ellen’s input. Ellen deserves your serious consideration.”

Timeline Contractors
ADU Contractors in Keystone
Average rating: 5 out of 5 starsFebruary 25, 2024
“Working with Shane and the Timeline contractors team has been a refreshing change from the typical general contractors. They source the best subcontractors and always have someone on site when any subs are present. They do what they say at every step of the project. We have a late 1800s home and they handled everything from permitting to execution.”

Garden City Design Build

Average rating: 5 out of 5 starsFebruary 16, 2022
“Leslie has been a joy to work with. She has helped us convert several of our rooms including a boring builder grade dining room into an evening sanctuary for our family to gather in. She listened to what we wanted and needed in a space and then beautifully designed every detail.”
Sopher Sparn Architects LLC
ADU Contractors in Keystone
Average rating: 5 out of 5 starsMarch 10, 2014
“A fantastic experience on a major renovation to a 1970's ranch. The Team at SSArchitechs worked with us from the first concepts for the plan until we moved into the house. The entire team turned our wish list into a complete vision. Every step of the plan stayed on schedule and on budget! We would definitely use SSArchitects on our next project.”

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 Keystone. 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 Keystone: 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.
