OC Builders Group
ADU Contractors in Orange County
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.”

Cutler Construction Services, Inc.
ADU Contractors in Orange County
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.”

OCTOBER 5 Fine Home Builders
ADU Contractors in Orange County
Average rating: 5 out of 5 starsJuly 10, 2015
“Our extraordinary custom home, designed and reconstructed by October 5 Fine Home Builders is undeniably a work of art. October 5 offers superior design and execution, where form and function converge. Ryan, the project superintendent, attends to every detail with an eye for quality and perfection. Their open-floor plan design blurs the lines between indoor and outdoor spaces, light abounds in every room, yet the space remains purposely private and intimate. Originally constructed in 1953, our home had not undergone any remodeling or updating. During construction, the house was all but demolished - leaving only the rough framing and portions of the exterior stucco and siding. Earthquake updates, 200 amp electrical service, beefed-up insulation, plumbing, heating and air-conditioning, smooth drywall, wide-plank flooring, bathrooms, kitchen, and dual-glazed windows supported the bulk of the project, which lasted 4 ½ months. With clean contemporary lines, the modern floor plan, great for entertaining, offers a celebrated life-style. What a beautiful and relaxing way to enjoy life! We say, “Call October 5 to celebrate your 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 Orange County. 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 Orange County: 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.
