"I hired OC Home Builders Inc. to build an ADU for me. Their service has been great. Jim and America did a good job keeping the project moving and taking care of issues as they arose. In particular I felt they kept me well informed about what was going on with job as it progressed. Jim made some great suggestions along the way to improved the finished product. This is a family company and I felt I got to know and appreciate all of them during the course of the project. They all work very hard to get the job done. As a home owner, I highly recommend this company to anyone who needs a general contractor for major constructions work."

"Our initial meeting with Suj was great. Initially, we had in mind a much larger job. He had quoted us $3000 for the closet demolition / wall rebuild (non-load bearing), packaged with several other items. Together with the fee for drawings ($4000) and permits, this was a bit higher than we anticipated. However, we decided to go with Suj due to his responsiveness and professionalism. Out of our other quotes, Suj’s pricing was middle of the pack - not the cheapest or most expensive. When the drawings were complete and evaluated, he gave us an updated cost of $6000 over text message. The scope of work had changed, and this was no longer part of a bigger project - understandable. The issue was when he gave us the official estimate a week later and up’d the price once again to $9000. When asked what happened, his exact words were “well, I need to get paid too”. He had weeks to consider before quoting the $6000 and nothing had changed since then. The extra $3000 may be insignificant compared to most renovation costs, but for us in our first home, this was back breaking. We continued with Suj since we were already locked in and well past the 3 day cancellation period. Their work for the most part was exceptional. The new wall blended perfectly into our existing structure, and the ceiling patch was also well done. The problem here was the floor. They had dug up a 1” deep pit in the floor, likely to remove the wall studs. However, they did not patch the floor or even let us know this was going to be an issue. We were never told about the pit until I decided to check in on their progress one day towards the end of the wall build. This required us to pay a handyman to come in next day on a weekend to patch the concrete since we had cabinets being installed the following Tuesday. Suj was aware of this and did not believe it pertinent information. Overall, Suj and SoCal Builders do quality work, but the issues in pricing consistency lost us before the work even started. Not even telling us that we’d be left with a 1” deep pit in our floor after was another huge issue which should’ve been brought up much earlier. This was our first experience with a contractor and I’m not sure if this is typical or not. However, it’s enough to make me doubt I’d contact them for any future work."
Completely renovating both the guest and master bathrooms. In the master bathroom, we're installing a spacious walk-in shower featuring dual black-finished shower heads, elegant floating benches, and marble wall tiles. Meanwhile, the guest bathroom will have a sleek built-in tub and stylish hexagon tiles.
This project involved adding a new master bathroom to the existing house. The shower features sleek white subway tiles complemented by striking black fixtures and shower door hardware. The bathroom floor is adorned with elegant white marble tiles, providing a seamless and luxurious finish. A white shaker vanity topped with a white marble countertop completes the space, creating a clean and sophisticated look.

"I can’t say enough good things about D2A Construction and Dani, our project manager. From the very first consultation to the final walkthrough, everything went smoothly. Dani was incredibly professional and always kept us in the loop. The kitchen remodel was done on time and within budget, which was a huge relief. The crew was respectful, polite, and left the place clean every day. I really appreciated how Dani handled every question we had without making us feel like a hassle. The craftsmanship is top-notch — our kitchen looks better than I ever imagined. Highly recommend them if you want a no-stress remodeling experience."

"I cant explain enough, just how wonderful of an experience we had with Newland. The professionalism and patience that we received throughout the entire process gave us the assurance and value that we hoped we would get from such a demanding job. Our home and family were treated with respect, our ideas were welcomed and now the quality of our home life is forever changed for the better. We began meeting with contractors to see what could be done so that our home could better suit our needs. We met with two other contractors before we met Terry with Newland. After our initial consultation with Terry we knew that Newland would be the company that would help us to make our home dreams a reality. We now have exactly what we wanted in an addition and our home is comfortable and beautiful. Our family of six is now happy and peaceful, and we aren t cramped and crowded for space anymore! The new master bathroom is so stunning and spacious that weve actually spent a significant amount of time in there just visiting with guests when we are showing off the remodel. We have well designed storage spaces, and our staircase fits beautifully in the downstairs space it took up. If we have any home-improvement needs in the future, we will absolutely go with Newland again!"

"This is the second home remodel project that Kyle Beym Home Improvement has done for us. We were so impressed with our exterior home renovation they did a few years ago, that we contacted the company again when we were ready to remodel one of our bathrooms. They were by far the lowest bid, and once again excelled in quality of work and end project. The crew was hardworking and respectful, working long hours and always cleaning up at the end of each day. We were once again pleased with the responsiveness to all questions and changes we made as the remodel was underway, and the bathroom was finished in the time frame that was estimated at the start of the project. The bathroom turned out even better than we had hoped! We are so pleased with the remodel that we can’t wait to do the rest of the bathrooms in our home."

"We are so glad we chose Coastal Kitchens and Baths Inc. for our remodeling project. They did such a great job on our master bath, guest bath, and the flooring throughout our house. The luxury vinyl looks amazing and completely transformed our home. John was very hands-on and made sure everything was completed with attention to detail. I could even text him late in the evening—sometimes around 9:30—and he would respond right away. That level of communication and dedication made the whole process smooth and stress-free. We are extremely happy with the results and would definitely use Coastal Kitchens and Baths Inc. again."

FAQs for addition to existing structure building service projects in Irvine, CA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
