About DB Construction

DB Construction – ADU Contractor Serving Greater Los Angeles

DB Construction is a full-service ADU contractor and room addition builder operating throughout the Greater Los Angeles area. They handle projects from the initial permitting stage through to turn-key completion, offering homeowners a structured path to adding legal, permitted living space to their properties.

Accessory Dwelling Units have become an increasingly practical option for California homeowners. Updated state ADU rules have made it easier to build legally, and a number of cities now offer pre-approved ADU plans that can help streamline the permitting process. DB Construction works within this framework to help property owners take advantage of these opportunities.

Types of ADUs and Additions DB Construction Builds

DB Construction works on a range of project types, including:

  1. Detached ADUs – Standalone backyard units, sometimes referred to as backyard cottages, granny flats, or Casitas, built as separate structures on the property.
  2. Garage conversions – Converting an existing attached or detached garage into a livable accessory dwelling unit.
  3. Junior ADUs (JADUs) – Smaller units created within the existing footprint of a home, typically up to 500 square feet.
  4. In-law suites – Interior or attached units designed to accommodate extended family or generate rental income.
  5. Room additions and home additions – Expanding the existing home with additional bedrooms, home offices, or general living space, all built with full permits and a defined timeline.

For homeowners who need more space but prefer not to build a detached unit, room additions offer a practical alternative. DB Construction designs and builds these expansions with the same permitting process applied to their ADU projects.

What to Expect Working with DB Construction

DB Construction positions itself as a full-service ADU builder rather than just a general contractor. This means they manage the permitting process in-house, which can reduce delays and keep the project moving on a clearer timeline.

Their process typically includes:

  1. A free initial consultation and cost estimate
  2. A step-by-step breakdown of ADU construction costs
  3. In-house permit handling to help keep timelines on track

Cost transparency is part of their approach. Homeowners are given a clear picture of what the project will involve financially before work begins, which helps with planning and budgeting.

DB Construction serves the broader Greater Los Angeles region, making them an option for homeowners across a wide geographic area who are looking for an experienced accessory dwelling unit builder to manage their project from start to finish.

"I truly can't recommend David Balmas Construction enough. David and Yaniv were so fantastic to work with through our massive construction project which included renovating our garage into an ADU, redoing out driveway, putting an outdoor kitchen in our backyard and turning our front yard into a courtyard. They helped us out every step of the way from walking us through the permit process, offering numerous ideas on how to make our ideas go from good to great and truly listening to us and fixing any problems whenever we had concerns. Any worries we had were immediately eliminated after a quick phone call or text message because we knew they wanted everything to turn out perfect in the end. Their communication skills are top notch and we will definitely be working with them again on future projects!"

"We have used DB Construction for a variety of situations, from handyman work to painting. He always provides first class quality at affordable prices, and monitors very closely his co-workers and the quality they provide. Our biggest job he did for us was installing a drainage system in our backyard, including a long French drain and sump pump. We've had no issues with its functioning through a few heavy rainstorms. We will continue to hire Dave as long as he stays in the business, which we hope will be as long as we keep our home."

"After dealing with a disappointing contractor, I was fortunate to find David Balmas. He stepped in and completely transformed my renovation experience. What impressed me most was his unwavering commitment to qualityrefusing to consider the job complete until every detail met our exacting standards. I appreciated his attention to detail and reliability. I highly recommend him for anyone seeking a contractor who truly takes pride in their work."

"Over the last decade, David has done a number of construction projects for my husband and I. From a full addition of a master suite, to kitchen remodel, bathroom remodel, building custom cabinetry doors, windows and more. His workmanship is incredible and the results are stunning. He cares passionately about the quality of the work and doesn't nickel and dime you - if something comes up during the job he often times will add it in, without charging extra. For example, in our last bathroom remodel, he discovered some issues with the electrical wiring in the wall and took it upon himself to replace all the wiring. That was something that wasn't included in the job scope and he didn't charge us extra for! Were now getting ready to do our second addition on a a new house and he is the only person I trust."

"David Balmas Construction is currently fully renovating my entire condo and I couldn't be happier with the results! From the initial consultation his professionalism, attention to detail, and commitment to quality are truly outstanding. The team was communicative throughout the entire process, keeping me informed of the schedule and any necessary decisions. They were also incredibly respectful of my home, ensuring a clean and organized work environment. The craftsmanship is exceptional. My new bathroom is on its way to being both beautiful more functional while feeling like a spa retreat. David Balmas and his crew clearly take pride in their work. I highly recommend David Balmas Construction to anyone looking for a reliable, skilled, and trustworthy construction company. They exceeded my expectations, and I would definitely use them again for future projects. Thank you, David Balmas Construction, for transforming my condo."
