ADU Testimonials & Reviews



Here’s What People Are Saying

Orange, Ca. | ADU

Keith built our stand-alone 720 sq.ft. ADU with his experienced subs from the ground up. This was a huge project designed by a professional architect that brought many unexpected challenges. This is where his 38+ years of experienced proved valuable as he was able to help us navigate, and call audibles along the way to make it happen.

All permit inspections passed with flying colors. His contract is detail oriented, so all parties know what to expect. And even then, on a project this size, there will need to be some negotiating along the way. Keith followed through and made everything right. He’s a straight shooter and keeps his subs in line. Final result is a beautiful, well-built ADU that we are very happy with. Remember that patience is golden when you embark on something like this. It’s a ride but well worth it in the end.

Early 2020, I started looking into converting my garage into an ADU. Most contractors offered to come out and give me a bid, etc. Keith was different, he told me to contact the city and see if it was even a possibility. Turned out according to the laws in 2020, my property wasn’t large enough. The other contractors would have wasted their time and mine.

When the laws changed in 2021 I remembered how impressed I was with Keith and called him. After meeting with him and reviewing how he did business; itemized statement of costs and a very clear contract, I hired him.

We started just before the COVID shutdown. Nothing was business as usual. City Hall was shut down and all normal procedures were all askew. Keith and his group were wonderful through the whole process. They went above and beyond and helped me every step of the way. I should mention that I’m a widow and really needed all the help I could get.

I have handled several construction projects since my husband passed and every contractor took advantage of my situation. Keith and his crew were honest, above board and did everything they promised. I would recommend them to anyone looking to add an ADU or any other construction project. I will definitely ask them first for any future projects!

It’s a daunting task to find a contractor and a designer to put your ideas of your dream remodel project into an executable plan that you and your family feel suits your needs and wants. Enter Orange County Construction. We found Keith on the web at one of those remodel sites. He responded to our initial request immediately and frankly the entire project followed the same kind of responsiveness.

I found Keith to be a man of integrity who would stand by his word during the entire project. He did not waver from what he promised and he delivered on every promise. If you have ever attempted a project as complex as a total home rebuild you know that there are so many things that can go wrong. Keith always kept me in the loop in terms of when we had to adjust plans, to pick out fixtures, countertops, cabinets, etc and this helped to keep the job on schedule.

I chose Keith because I felt that he had the right temperament to deal proactively with all the subcontractors and the city of Huntington Beach. As it turned out he managed the project very well and even though there were many changes that occurred during the process, he kept it moving forward on a steady course to a most satisfactory conclusion. I highly recommend Orange County Construction not only for their workmanship, but also for the high integrity that Keith brought to the project. I am a straight ahead person who talks in plain English and so does Keith. I found the experience to be very successful and I can tell you that both my wife and I could not be happier with the results. Take a look at the pictures of the project on the site and you will see a very well built home designed expressly for my wife and I, to our specifications and all expectations were met.

One of the biggest issues around a project of this size is what happens after its conclusion. In our case all the small punch list items have been addressed in a timely manner and Keith’s integrity continues to be exemplary.

Orange County Construction, under the leadership of Keith Daigneault, took our dreams of more “family space” and made it a reality! Design, along with practicality, allowed us to get the most out of our budget. Most importantly, Keith works well with the city which kept the project on time, and done right the first time! Thanks for a job well done.

Orange County Construction was very instrumental in helping us design our dream home. From start to finish, they kept us informed with ideas. From offering us an accurate price in writing to completing our project on time, they really made remodeling a delight! I refer them to anyone I meet looking for a General Building Contractor for ADU’s or room additions.

Corona Del Mar, Ca. | Large Addition & Remodel

I did a major remodeling in my house in Corona Del Mar. I interviewed three general contractors . I found Mr. Keith Daigneault (Orange County Construction) to be honest, straightforward and motivated. He detailed the construction process and cost very clearly so I decided to go with him. He was great throughout the construction and finished the job on time. Since then I have had several consultations with him for various projects and he has been responsive, courteous and helpful.

Working with Keith at Orange County Construction made all the stresses of doing a home remodel easy to handle! Keith was so helpful in directing us to sources for quality interior products like windows, doors, flooring, tile, bath fixtures, etc.

His guidance and expertise helped us through the tough decisions. Family and friends have given us rave reviews on our “new” house!

On a scale of 1 to 10, we’d give Keith and his guys a 10+ !

When my mother passed away and left me the property she owned, my husband and I decided to take on the challenge of rebuilding. The property needed a lot of work, and there was no alternative but to start from scratch. I was excited and scared at the same time, for I have heard such horror stories from other people about contractors. We met with many companies and the one that stood out the most was Orange County Construction.

Keith showed professionalism from the start.
His knowledge of building and city codes, as well as construction procedures, showed his true strengths. He is honest and upfront with his information. During every phase of construction he kept us informed and was always available to answer any questions we had, and we had many! We had no problems with inspections from the city, with most inspections passing the first time.
One thing that stands out the most for us, is the pride and quality everyone put into their specific job. It wasn’t done, unless it was done right. Now that our home is built, I know we made the correct decision in hiring Orange County Construction. Our home is now a reality and I have no horror stories to tell. Mom would be proud and I am overwhelmed, thank you Keith!

 Cypress, Ca. | 1st & 2nd Story Room Additions

We decided to add an extension to our house, which included adding a couple of bathrooms, 1 upstairs and 1 downstairs. After talking to a few General Contractors, some were very hard to get a hold of or willing to come over, Keith from Orange County Construction was very nice and enthusiastic about our project. During the site walk he pointed out several ideas that we found to be great, and we included them in the build and some suggestions to think about because it wasn’t ideal for our project. He was very patient with us as we made several changes before our project even started. Once the project started, he was consistently in touch with us updating us on every step. He also didn’t overwhelm us with phone calls, he only reached out to us if there was something to report. His workers were tremendous, clean, and polite. The project moved along a lot quicker than expected, not including waiting for the inspectors. All the inspections passed the first time and even the inspector commented on how clean the work looks.

After the project was complete, my wife and I were extremely satisfied with the end result. It was better than what we originally sought or, thanks to Keith’s suggestions.

We would definitely work with Keith and Orange County Construction again and we highly recommend them for your project.
