"Construction Masters took care of all our landscaping work including building an outdoor bar/kitchen, pavers, imitation grass, cement work, brick work, fountains and other miscellaneous work. They did an amazing job! Their crews were on time and cleaned up after themselves. I highly recommend Construction Masters."

"I would suggest Bob and Nicole. We hired Platinum Home Builders to complete a difficult project that included moving and relocating a 100-year-old Douglas home, pouring a new foundation, and installing a new floor plan and a completely developed basement. I would go into more detail, but I believe the most important thing we learned was how much we trusted Platinum Home Builders to do the correct thing and make the right judgments."

"Pacific Ocean Builders kept on top of all the sub-contactors and kept me informed every bit of the way. The final result was a beautiful kitchen. All the workers from Pacific Ocean Builders to the sub-contractors were experienced, very professional and respectful. I would recommend Pacific Ocean Builders to anyone. You will not be sorry. Erez from Pacific Ocean Builders were exceptional and she got me through it all. We never knew anyone who was more customer oriented. He kept on top of every aspect of the job and kept us informed. It was a pleasure dealing with him..))"

"Ouriel from Universal Home Design converted my detached garage into a studio with a kitchen and bathroom, from July through October 2020. We were referred to him via friend who underwent a garage conversion the year prior. Our original garage was 450 ft. A 94 square foot axdition was added on for the bathroom and laundry area. The tile installed in our shower looks incredible! The studio is spacious, and we are super happy with the work that was done! The process from start to finish was organized and straightforward. Payments were made at different steps along the way based on the contract. Ouriel was easily reachable via phone and text the entire time. He answered all our questions and concerns, and got back to us quickly, which is not always the case in contract work. We actually recommended his firm to one of neighbors down the street. If you want an ADU conversion done, we would highly recommend him."

"I worked with Supreme Remodeling last year to rebuild house for me in Burbank last year. It was a long and arduous project that involved demolishing 50% of an old house down to the studs and then building an attached addition from the ground up. I sent out my completed architectural plans to at least 15 different companies, and took interviews with many of them. Received bids from maybe 5-6 different ones. Here's what the difference was. First of all, Micky the owner of Supreme remodeling took the initial meeting himself. He was in no way pushy or salesy in any way. He was patient (it took a month for me to come to a decision). I was able to look at ACTIVE construction projects that he had going on. He was extremely knowledgeable on all of the new building trends and he has a good eye for design. Once I signed on, it took about 9-10 months to complete. He has a good roster of subcontractors that he works with. But his inside guys Eddie and Ronell are outstanding. In the end the real difference that sets Supreme apart has to be the service. Micky and his staff are very available and responsive. Even on a Sunday night he's active and communicating the following weeks work. If there's an issue he's on top of it. And even though the initial cost of the project was high, you definitely get what you pay for and to be honest, it is a very common experience to have contractors to offer you a lower price just to rope you into a situation where they constantly barrage you with extra charges during the project because they weren't "in the contract". All in all I would definitively work with Micky and supreme again in the future on any projects that I have coming up."

"After interviewing seven other contractors, I chose We Build Home Efficiency because of their ability to work with me on a tight schedule. They built a custom bathroom vanity and installed it on time. They used quality materials and did a great job. Bar was particularly helpful and a pleasure to work with. I would hire them again."

"My husband and I just finished a remodel of our guest house in Sherwood Forest. We used a company called Universal Home Design Inc. The contractor and owner of the company Ouriel Lousky was most professional in every aspect of the job. His crews were timely and most efficient in every way. He had his subcontractors lined up so the job was never lagging behind. I would recommend him to anyone who is planning on a remodel or a renovation. Mary V."

FAQs for garage building service projects in Altadena, CA

A well‑constructed, properly permitted detached garage adds between $12,000 and $36,000 to a home’s resale value. Buyers appreciate the secure parking, extra storage, and flexible workspace, so appraisers often bump the property’s value accordingly. The exact return depends on the garage’s size, finishes, and how well it matches the main house, but most homeowners see a strong ROI when the build meets local codes and passes inspection.

Yes—once it meets local building codes and you secure the proper permits, a detached garage can be converted into living space. Finishing the interior, adding climate control, and ensuring safe egress effectively increase your usable square footage, though it may not always count toward the official listing. Skipping permits can trigger fines and even force you to undo the work, so always clear plans with your city first.

Most homeowners policies cover a detached garage under the “other structures” provision, but coverage limits vary. Review your declarations page and ask your agent how much protection you have for separate structures. If the limit is lower than the garage’s replacement cost, you can raise it for a modest premium. Confirming the details now prevents headaches if you ever need to file a claim.
