I have used DJ on multiple projects over the last few years. Everything from an add-on to new construction. DJ and his team have always been reliable and trust worthy. I find DREC to be extremely professional with very reasonable rates. We have used DJ 4 separate times over the last 3 years on 3 different projects. His demeanor is extremely professional and he is easy to communicate with he never comes off pushy or arrogant. He is extremely knowledgeable and seems to have a strong mind for attention to detail. DJ walked the job site nearly everyday checking on the status of the job. Highly recommend this business.

I am not big on posting but, I am so happy with the outcome of my addition I just felt it was important to share. I already had plans ready for DJ and he priced me out at a great price and stuck to it all the way through. The quality was great, really like the workers, nice guys. Everything was good!

I had a good experience with this company. The quality was great, but the cost was much more then I had expected. I had many changes through out the process that I wanted for things I did not know at the time when I first did my plans. DJ recommended these changes and they were good ideas but it caused my over all cost to increase by a lot. If I had to do it again I would not have made those changes. I am on a fixed income and those changes caused my monthly payment to go up almost a $90 a month. I am not happy about that. I think for certain people those upgrades would be nice but for me they did not help me and I never plan on selling my house so the added value means nothing”.

I already had approved plans with the city when I meet with DJ. My ADU took roughly 4 months to build from the time we signed the contact to the finish. I would use them again without a doubt. It was a rough start in the beginning because the city inspector who seemed difficult to deal with and delayed us for a few days over set backs issues but we worked around those obstacles and now we are pleased with the final product.

We hired DREC Construction to build a 1,800 sqft add-on to our existing home. The entire process took just about 7 months from start to finish. I am extremely pleased with not only the quality of craftsmanship but also the professionalism of each and every employee. We spend just under 2 months in planning and then once that was through these guy moved fast and never missed a day. Thanks guys and I will be calling you for my Newport Beach house. Talk to you soon.

I am not one for writing reviews, its just uncomfortable. However, after my experience with this company I am truly pleased and thought I would share that. This is my first time working with a contractor. These guys were great. I had a detached ADU built in my back yard in less than 6 months and 45 days of that was the city delay for plans. These guy work fast and clean. I can’t recommend them enough.

We just finished our ADU, or in our case it’s my Mothers new home. We are so happy that this was super simple. DJ and his staff took care of everything. This process was so stress free and they finished ahead of schedule. Only issue we had was the yard was very messy, they had to dig up our beautiful flower. I still give them a 5 star rating! Thanks again for all your help.

I typically am not a fan of posting reviews but in this case I thought it would be appropriate. We built a new house on the back of our property and added on to the existing home. We interviewed 3 different contractors and finally choose to go with Drec. We spook with DJ over the phone and I think that the main reason we chose them was right from the start they seemed extremely transparent. I never felt that pushy sales man type pitch. There were vary knowledgeable on all the codes as well as what would be required from the city. The craftmenship was superb and they did a really good job of keeping our work site clean everyday. That was important to me. Overall this company out performed my expectation.

We finally decided to build our ADU and after all this time we decided to moved forward with DJ at DREC Construction. This was the right move, we are super happy with the level of professionalism as well as the quality of work. We had no idea of construction, that is why we choose to go with DJ. He walked us through the entire process. He handled everything, engineering, plans, permits, and really helped out with the design process. DJ’s team was great. I am very please with the final product and would recommend DREC to everyone.

I have been dealing with DREC Construction for months. They are very professional and do quality work. They follow specs as required and are always prompt. I would recommend that if you have a need for a general contractor-reach out to DREC Construction. You won’t be disappointed.

The DREC ADU Difference

ADU CONSTRUCTION SERVICES IN SOUTHERN CALIFORNIA

One of the most common questions we are asked when we first speak to a prospective ADU client is what separates us from other ADU home builders in Southern California? The answer for us is simple! We have years of experience, great customer service and a competitive pricing.  Our attention to detail that makes us your top pick, and our level of quality is years ahead of our competition.

We have spent the past 2 decades building Single Family Residents, Commercial Properties as well as High-End Spec Homes. This experience has led us to become the leading Southern CA home builders.

We have been building ADUs in Southern California before there was even a term used. We typically called them garage conversions or mother-in-law houses or granny flats. It is only recently that the term ADU (Accessory Dwelling Unit) has become so popular.  Once California passed the most recent Assembly Bill (AB) 1584 the term has become so well known that our industry has blown up.

Beyond pulling permits and building to code, we have earned the reputation of being the green energy and green-conscious contractors of Southern California.

The changes to the ADU laws have led to many new tax credits. Feel free to give us a call today so we can get started with your one of a kind ADU construction .
