Featured Reviews for ADU Contractors in Orange County

Gil Construction
ADU Contractors in Orange County
Average rating: 5 out of 5 starsDecember 31, 2021
“Gil Construction exceeded our expectations in so many ways. They were prompt and courteous and did excellent work in adding a bathroom to existing space. Jim Elliot, the owner, suggested a better placement for the bathroom which resulted in a much better bathroom and came in on budget. Additionally, their estimate was the best we received. They were all a pleasure to work with and went above and beyond in everything they did. For additional house projects I will absolutely consult them first.”
Southern Image Design Builders
ADU Contractors in Orange County
Average rating: 5 out of 5 starsNovember 30, 2016
“I had the pleasure of working with Jean and Jeff of Southern Image Design Builders on a screened enclosure on my home. It wasn't just any screened enclosure - it was an A-frame design with a tower leading to a spiral staircase down to our first-floor. They were wonderful to work with -- on time, on budget, with many excellent suggestions on design features from Jean. I would hire them again and recommend them without hesitation.”
Outlaw Design Company
ADU Contractors in Orange County
Average rating: 5 out of 5 starsJuly 29, 2013
“Ruth Ellen completed a whole-house renovation (2003) and a screen porch design (2012) for our family. She is insightful, practical, and thinks of things to incorporate into her designs that we never in a million years would have thought of. She's got inter-personal and listening skills that would make a professional mediator jealous--traits that come in handy when managing the expectations and goals of a builder, owner, and even spouses! Working with her has always been a pleasure, and ten years on we are proud to call her our friend as well as our architect.”

They treated our home like it was theirs.”
Outdoor Building Concepts
ADU Contractors in Orange County
Average rating: 5 out of 5 starsOctober 11, 2017
“Our house expansion/renovation is still ongoing....target completion is January of 2018. We are transforming our 2800 s.f. lake house into a 5600 s.f. dream home plus a large, 3 car, attached garage. We have found Outdoor Building Concepts (OBC) a fantastic company to work with. Before starting this project we went back and forth with them for over a year (planned) and found them very accommodating. What sold us was the fact that when we went to look at some of their other additions they looked like they were part of the original house. We have made some minor changes along the way and they are more than happy to accommodate our requests...many times without changing (increasing) the budget. We are the type of people who liked to be involved in all aspects of our project and OBC seems to welcome this. We look forward to the completion of our dream house and will no doubt have OBC at some of our open houses to take a bow.”

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.
