Featured Reviews for ADU Contractors in Westminster

OC Builders Group
ADU Contractors in Westminster
Average rating: 5 out of 5 starsJuly 5, 2019
“We hired OC Builders for a full Kitchen remodel and an installation of a 20’ sliding door. When we met our contractor, Moe, he went over everything in detail and answered all of our questions. Moe was happy to give advice on materials and design but was also fine working with our design. It was a nice balance. We’ve had mixed experiences with contractors on smaller projects in the past but we’re so glad we hired OC for this project. Everything went as expected and there were no surprises. The original quote was pretty close to what the final charges were and the timeline went very smoothly. Moe was extremely communicative and addressed any issue we had in a timely manner. The site was always left very clean every day and the workmen were very professional. We are finished now and loving everything about our beautiful open kitchen and large new doors that open to our back yard. We will not hesitate to hire OC Builders again for future projects.”
Horizon Construction & Remodeling
ADU Contractors in Westminster
Average rating: 5 out of 5 starsJanuary 31, 2013
“We enjoyed working with Mark and Enna to remodel and update our master bathroom. Mark was especially helpful during the planning phase when he listened patiently to our endless questions and provided useful information and suggestions that helped us reach decisions about project materials and stylistic choices. After work began, Mark and Enna continued to be very responsive to us regarding scheduling aspects of the work and finalizing decisions about the details. Throughout the process, they stressed that the goal was to create a master bathroom that we would really enjoy, even if that meant occasionally changing our minds about details or adding new work at times. This was our first major renovation project, and we feel that Mark, Enna and their team did a great job guiding us through it and creating a great new room to enhance our home.”
Cutler Construction Services, Inc.
ADU Contractors in Westminster
Average rating: 5 out of 5 starsJuly 13, 2014
“Cutler construction renovated three bathrooms for us, two on the second floor. That included tile flooring (with special materials to avoid cracking), custom vanities, granite counter tops, lighting, exhaust fans, and mirrors, as well as painting. They replaced several ceiling fans, all of our smoke detectors, and added CO detectors. Their work was professional and high grade: no bs, no missed deadlines, no cheating on quality, just total honesty and great craftsmanship. We are extremely pleased and will use Cutler construction in future projects.”
Platinum Home Builders & Design, Inc
ADU Contractors in Westminster
Average rating: 5 out of 5 starsOctober 20, 2021
“So pleased with my new shower from Platinum Home Builders & Design! The process was so quick; I had my dream shower installed in A Few days ! I didn't think that was possible - I had the same shower tiled in '08 and it took nearly a month to install. I couldn't take looking at the moldy walls any longer - no matter how hard I cleaned nothing helped. I am so thankful for the Microban feature; it keeps my shower clean and keeps me protected. Everyone I spoke with/interacted with was so friendly - this experience was a true pleasure. Thank you, Platinum”

OSH Construction
ADU Contractors in Westminster
Average rating: 5 out of 5 starsFebruary 19, 2024
“I called four contractors for a estimates on a new fully permitted bathroom on the second floor bonus room above the garage. Sergio responded in a timely manner. We setup an appointment for him to look at the space. The space is very small. His quote was very reasonable and one of the best out of the four contractors. Sergio and his crews arrives early as scheduled on Monday and proceeded to demo. They updated me at the end of the day everything they work on that day. Which was very helpful on the status of the construction. They work through Saturday and they even work on one Sunday to finish the job. The whole crew were a pleasure to work with at all time. I am so glad I contacted Sergio for this job. He is a pleasure to work. He explain to me what and why needed to be done. He also recommended to me where to purchase the bathroom tiles, vanity & faucet. He even installed my new garbage disposal at no cost. I am very happy with the new bathroom, it look fantastic. The workman craft was excellent and beyond my expectation. I definitely will work with Sergio and his teams again in the future. I would totally recommend working with this company again.”

Jeannette Architects
ADU Contractors in Westminster
Average rating: 5 out of 5 starsJune 20, 2012
“My wife and I hired Jeannette Architects to assist us with a major remodel (interior/exterior) of our 3,500 sq. ft. ranch style home in Newport Beach. The task: incorporate warm contemporary design into our 1970's "woody cabin." As a real estate developer and because it's our third major house remodel there were many design elements we knew we wanted but many more that we needed help with. As capable as Jeff (Jeannette) is with his design sense, we believe that it's his ability to listen to his clients, understand client goals, how we will live in the space and how that fits into our budget is what sets Jeff apart from other architects. The Jeannette team met aggressive time constraints, produced a thorough set of construction documents, were always quick to provide clarification and answers to our questions and were great resources for product and material options and information. True professionals that we would use again and confidently refer to others. Our project is nearing completion and I can't wait to share photos.”

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 Westminster. 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 Westminster: 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.
