"OC Home Builders remodeled the interior of our home (kitchen, two bathrooms, one laundry room, structural upgrades, fire place) and everyone on their team worked incredibly hard to complete our project. They worked great with city inspectors and have great relationships with them. America and Jim were available whenever we had questions and always gave great value for their work. They were willing to work with other contractors and be flexible to adjust to our schedule. Their entire team takes a lot of pride in their work and they want to make their clients happy. We would definitely recommend to others."

"After several long years of designing and permitting our home remodel during the pandemic, we were searching for a good contractor to build out our remodel and second story addition. Avi and David were wonderful; very thorough in explaining the process, answering all of our questions, and settling on a price that was reasonable and within our budget. During the building process, David was very responsive, available, and receptive to changes and last minute decisions made along the way. The project took longer than anticipated and there were some unexpected setbacks, but David and Avi worked quickly to fix issues and keep the project moving forward. At the end of the project they were very responsible about making sure we were satisfied with every last detail before completing the project. Our new home is beautiful and we're very happy with how it turned out, thanks to David and all the crews at So Cal Builders."
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.

"We hired D2A Construction to build a detached ADU on our lot, and I’m still in shock at how smoothly everything went. Dani was an incredible project manager — responsive, honest, and always willing to take the time to answer our million questions. He kept the entire job running like clockwork, even when we had a few unexpected city inspection delays. His team was fantastic and the craftsmanship was solid across the board. We now have a modern, fully functional unit that we’re planning to rent out. It blends beautifully with the main house, and people can’t believe it’s a new build. If you want a company that actually delivers what they promise, D2A is it!"

"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."

"We recently hired a construction company to complete an addition on our home, and we couldn?t be happier with the results. From the very first consultation to the final walkthrough, their professionalism, transparency, and attention to detail truly stood out. The team took the time to understand our vision and offered thoughtful suggestions that improved both the design and functionality of the new space. Throughout the project, communication was clear and consistent. We always knew what phase we were in, what to expect next, and any questions we had were answered promptly. The quality of workmanship exceeded our expectations. The addition blends seamlessly with the original structure of our home?it looks and feels like it was always meant to be there. The crew was punctual, respectful of our property, and kept the worksite clean and organized each day. We highly recommend this company to anyone considering a home addition or renovation. "

"We performed a whole home renovation inclusive of a bathroom addition. We needed design and build services for a 1960s home. The team was extremely professional and communicative which made for a smooth and thoughtful experience. The team was very organized in their execution and ensured all the decisions were made in a systematic fashion making the process feel easy. The day to day work staff was so respectful of my family as trades came in and out. For such a large project, it felt easy and detail oriented. We love the final product. It is absolutely beautiful."

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.
