"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 recently worked with HA My Design to build an ADU, and I could not be happier with the results. Golan and his crew were always on time and worked hard to ensure the project was completed within budget. The quality of their work was excellent, and they were quick and efficient. I highly recommend HA My Design for anyone looking to build an ADU. Their one-stop-shop showroom, covering 5000 square feet, made selecting finishes a breeze. I will definitely refer them to friends and family!"

"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."

"To hire a contractor who started out in the Plumbing business could not have been a better choice for a bathroom remodel. Everything went wonderfully. They knew the law so I was able to do things correctly. They had ideas that even I did not have, having dreamed about this for a few years. The contractors son, who was also a licensed contractor was the main person on the job and here every day. I would HIGHLY recommend them. The price was fair and competitive."

"Had our roof replaced by the awesome team with Nathan behind the wheel. Very professional and no hidden costs, upgrades, etc. Very timely and up to standards. I cannot recommend them enough to anybody needing anything. In fact, we will be reaching out for future improvements on our small bungalow in LA. Also, be assured that they are not some "new to the game" company as there are a lot of them."

FAQs for addition to existing structure building service projects in Fountain Valley, 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.
