Expert Room Addition in West Hollywood, CA

A room addition is one of the most direct ways to add usable square footage to your West Hollywood home. At DTA Green Construction, we handle the full scope of work: design coordination, structural framing, electrical, plumbing, insulation, drywall, and finish work. We build additions that connect cleanly to your existing structure and match its look from the street. West Hollywood lots tend to be compact, and the city's zoning code sets floor area ratio limits that vary by zone. Overlay districts like the West Hollywood West Neighborhood Overlay District also apply design standards to additions in R1-B zoned areas. We review your property's specific zoning before any plans are drawn, so the scope we propose is buildable on your lot. Whether you need a larger primary bedroom, a dedicated home office, a family room, or a ground-floor suite for a family member, we plan the addition around how you actually use your home. Call us to talk through your project.

Room Addition FAQ

Common questions about room addition in West Hollywood, CA.

Yes, a room addition is often possible on smaller West Hollywood lots, but the buildable area depends on your zoning district and floor area ratio limits. We review your property's zoning before drawing any plans so you know exactly what fits.

Our room additions in West Hollywood cover structural framing, electrical, plumbing, insulation, drywall, and interior and exterior finish work. We coordinate all trades from start to finish under one contract.

Yes, some West Hollywood properties fall within neighborhood overlay districts that set additional design standards for additions. We check your specific address against the city's zoning map before any work is scoped.

We plan the work sequence to keep disruption to your living areas as limited as possible. Most of the structural work happens at the addition footprint before we open up the connection to your existing home.

A room addition expands your main living area and stays connected to your home, while an ADU creates a separate unit. We can walk through both options with you based on your West Hollywood property and your goals.

We hired DTA Green Construction to update our new construction house build out in LA,and we’re still amazed by the attention to detail, Tomer worked with us on the floorplan layout and material selection, and it felt like a true partnership. From the cabinets to the lighting to the backsplash, every detail was beautifully executed. The whole team was punctual, respectful of our space, and super responsive. Even the cleanup was handled with care, which we really appreciated. Our new house addition now feels Amazing , more spacious, and far more functional. Highly recommend him and his team. After interviewing three contractors, we chose this company to build our 450,000 addition. Tomer was thoughtful in his planning and provided multiple layout suggestions that really improved flow. The work crew stayed on schedule, and materials were delivered promptly. the office gave us regular updates and made sure our concerns were addressed along the way. The end result is a luxury-style home that rivals anything you’d see in a magazine. Their team genuinely knows how to manage a project from start to finish. It was such a good experience.

For anyone in need of a contractor for construction jobs big or small, with Tomer and DTA Green Construction you get not only an excellent and proficient contractor to hire and supervise all the subs, you also get a designer, an idea guy, and a friend who cares about doing the job right and making you happy. Tomer is attentive and likes to do jobs as fast and efficiently as possible. No more waiting around while your contractor hustles other jobs that delay your project. After Tomer built two units for us, we hired him to remodel another property and build three more units at two properties. Five new one bedroom units and the remodel of a three bedroom house ran us about $1.4 million...an excellent price relative to the substantially increased value of our properties.

We needed to sell my Grandmother's house and get it ready for showing. The outdated kitchen was an issue according to our agent. We contacted Tomer/DTA Green Construction who was referred by our agent. Tomer came out and helped us with nice cost effective design since we had no idea where to even begin. We gave him a budget and he was able to do everything we needed within that price. Him and his crew were great. Tomer made this a fairly easy process and helped us with everything personally. Highly recommend these guys.

Tomer was wonderful to work with. I explained exactly what I wanted in my remodel and he was able to execute it perfectly. So wonderful to see my vision come to reality. He was fair in price and his work was exquisite. I will definitely use him again and recommend to anyone looking for a contractor.
