I am a licensed, bonded, and insured General Contractor with an extensive background in design and construction. I do not just talk the talk, I walk the walk, having physically labored in trades ranging from tile and plumbing, to foundation and framing. To this day, there is seldom a project I will not roll up my sleeves for, be it setting lines for a home addition, or laying out complex tile patterns to be reproduced by my team. I received my Masters in Architecture (M.Arch) from UCLA, where I graduated with distinction. My commencement thesis focused on the California Accessory Dwelling Unit (ADU) legislation, a space that I have become a leading expert in. Building home additions and creating additional housing in the form of ADUs is my lifework: there is nothing more rewarding than delivering a finished project to a client. If you are contemplating a home addition, major renovation, or building an ADU, give me a call. I look forward to hearing from you.

"I recently hired Sklar Construction for a major renovation on my home in Culver City, and I was blown away by their service. From start to finish, they were professional, detailed, and truly cared about my project. The team was fantastic at keeping me updated every step of the way. They answered all my questions and made sure I felt comfortable with the progress. They finished the project on time, and the quality of their work was incredible. My home looks amazing, and I've gotten so many compliments on the renovation. What really stood out to me was how Sklar Construction listened to my ideas and offered great suggestions to make my vision even better. They were committed to delivering top-notch results, and it shows in every detail. I highly recommend Sklar Construction. If you need a renovation done right and want to work with a team that truly cares, go with them. You won't be disappointed!"

"We just had our kitchen completely renovated by Beverly Builders Group, and we couldn't be happier with the end result! Lawrence was our contractor and he fully brought our vision to life!!! My family and I went out of the country while the kitchen renovations were done and Lawrence took care of everything for us. He was super easy to get in contact with when we needed him or had any questions. He honestly went above and beyond for us and I loved how transparent he was about the job along the way. I've worked with other contractors in the past that weren't so honest and it was such a nice experience this time around. Emily was our project coordinator and designer and kept us updated daily on what was happening. We were always in communication with her and she overlooked our shopping list of all appliances so nothing was missed on our installation dates. Their team was amazing and I highly recommend them to anyone who wants the best! We were so happy with them that our master bathroom"

From the dynamic custom design ideas to the minutest renovation details, Vertex Construction & Design in Los Angeles ensures the work we do for you is exemplary. With thirty years of general construction and design services, we specialize in creating new living and working environments.

"I could say that Brent of Vertex Construction is amazing at what he does, but that wouldnâ  t nearly be covering the scope of the review heâ  s worth receiving. As a home owner, one of the most valuable assets you can find is an HONEST contractor who knows his craft. Brent is exactly that. He does great work, is incredibly knowledgeable, but at no point does he ever try and overcharge you. Iâ  m very fortunate to have found him and the least I can do is share my experience with others as I know just how difficult it can be to find a contractor like Brent in Los Angeles."

"Efrain and David are fantastic! When our contractor was suddenly unable to continue with the job, David took over with a great positive attitude. He persistently worked with the city to get the building permit, finally ending a tedious 10 month process. Crews were here working every day. Each one of them was considerate, conscientious, and demonstrated a strong work ethic. Efrain and David communicated with us most days and were always accessible to us. My ADU is adorable and just what we wanted and I am sure that many contractors could have pulled it off. The important thing about Olalde is that they truly care and honestly want us to be happy."

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

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
