I can't say enough about the excellence of this company! Hired them to design and build a backyard ADU and could not be happier with the way it turned out! An incredibly painless and smooth experience from start to finish. Give them a go, you won’t regret.

Hired them to design-build a 2-bed dwelling unit on top of an existing 2 car garage and they did a fabulous job. Would highly recommend to everyone who is considering building an ADU in Los Angeles.

Words simply can’t express the level of appreciation we have for Danny at CCS Inc as they converted our unused garage space into an accessory dwelling unit in June-July this year. From design to financing and permitting to the project execution, every aspect of our project was well taken care of. Our converted garage meets our exact specifications and exhibits the highest levels of workmanship. Please forward our gratitude to everyone who contributed to make our ADU project a success. Thank you!

I cannot speak highly enough about the professionalism and expertise of these guys. They turned my basement into a beautiful and functional ADU a few weeks ago. The entire crew was incredibly professional, helpful and a pleasure to deal with. The project was finished on time with high quality and we are looking to enjoy our new dwelling for many years to come. A terrific experience. Will absolutely recommend them for your ADU project.

I just can’t say enough positive things about CCS Inc. We hired them to covert our garage into a two-bed ADU last month. From design to the final product, everything stayed on budget and the project was finished within the agreed budget and timeframe. We are exceptionally pleased with our new dwelling, which we rented in less than two weeks. CCS has certainly earned my highest recommendation.

CCS Inc. was recommended by my neighbor and am very happy that I went with this company. The whole process of my ADU project was completed on time and satisfactory. They were able to answer all my questions and patiently guided me through the whole process from start to finish with my 2bed/2bath unit. The team is very knowledgeable and precise. The job site was always cleaned and they communicated thoroughly throughout the job. I had several bids from their competitors and decided with CCS because of their professionalism and expeditious response in which reflect their great workmanship. I highly

As home investors, we wanted to generate rental income from new tenants, so we decided to hire CCS Inc to build a new ADU in our backyard. Danny was helpful in explaining the process of the project and the different stages it would go through. I was not happy with the amount of it time it took to receive the building permit. They took longer than estimated which made me frustrated even though they do not have control over this. Danny’s team of experts provided outstanding floor plans and did a great job in the construction.

I am very happy with my new ADU, thanks to CCS Inc. This company was both professional and attentive to detail when working on my project. They made sure the construction was done to my liking as they asked me for preferences. At first, I thought this was going to be a stressful experience but it turned out to be quite the opposite. CCS Inc. took care of EVERYTHING! From doing architectural designs, to getting the city permits, and doing the construction of the building, there was no need for me to worry. I have no complaints as it was a pleasure doing business with them.

I needed to renovate my garage into an ADU and had no idea who to contact. I started asking around and CCS Inc. was referred to me by a friend so I contacted them to arrange an appointment. The process began there as they provided architectural designs which were given to the city for approval. I am very content on how professional CCS Inc. was and how attentive they were towards the project. Not only were they able to provide architectural plans; but they were also in charge of the structural engineering, expediting city permits, and the construction of the building itself. They are a one stop

I hired CCS Inc to help create the plans and architectural designs for an addition to our house plus garage 1,179sq ft.  I explained to them what I wanted and they made it happen.  I also explained to them that I had already lost time and money with another "so called" architect and that I needed something done quick.  They provided me a floor plan within few days after our initial meeting and immediately made any adjustments I requested made.  Aside from small city corrections the plans were approved within 10 days.  Working with CCS Inc was great and stress free.  I highly recommend they
