About ORO Coast Builders

ORO Coast Builders: ADU Contractor Serving Los Angeles and the Bay Area

ORO Coast Builders is an ADU contractor and design-build company operating in both Los Angeles and the Bay Area. With over 25 years of experience in home construction and extensions, they specialize in designing and building Accessory Dwelling Units (ADUs) that integrate with the existing structure and style of a property. Their team includes architects, interior designers, and construction professionals who handle projects from initial concept through to completion.

ADUs — also known as in-law units, granny flats, backyard cottages, or casitas — have grown in popularity across California due to housing shortages, shifting legislation, and the increasing demand for multi-generational living arrangements. As an experienced accessory dwelling unit builder, ORO Coast Builders helps homeowners navigate these factors and find a solution suited to their specific property, budget, and goals.

Types of ADUs ORO Coast Builders Can Construct

There are several types of ADUs that ORO Coast Builders can design and build, depending on the available space and the homeowner's needs:

  1. Detached ADU: A separate residential structure built on the same lot as the primary home, often in the form of a small cottage or granny flat. This option adds square footage while maintaining a degree of separation from the main residence.
  2. Garage conversion: An existing garage is converted into a livable space, complete with amenities and sleeping quarters. This is a practical way to make use of underutilized space without expanding the property's footprint.
  3. Basement conversion: Similar to a garage conversion, a basement can be transformed into an independent living unit.
  4. Junior ADU (JADU): A smaller unit built within the existing structure of the home, suitable for limited spaces. These are comparable in concept to tiny homes and are a cost-effective option for homeowners with spatial constraints.

The right type of ADU will depend on factors such as the intended use, available space, local zoning regulations, and budget. ORO Coast Builders works with homeowners to identify which option best fits their circumstances. ADU projects can also be incorporated into a broader home remodel or commissioned as a standalone build.

It's worth noting that ORO Coast Builders does not offer prefabricated builds. Instead, they source materials and construct each unit to be fully customized to the client's specifications. Every design is planned in detail in close collaboration with the homeowner.

Practical Benefits of Adding an ADU to Your Property

There are several practical reasons homeowners in California choose to add an ADU to their property:

  1. Rental income: A completed ADU can be rented out, providing homeowners with an additional source of income.
  2. Increased property value: A well-built accessory dwelling unit can add measurable value to a property.
  3. Multi-generational living: ADUs offer a way to house elderly relatives or adult children nearby while maintaining privacy for all parties.
  4. Flexible use: Beyond rental or family use, ADUs can function as home offices, guest accommodations, or studio spaces.

From a regulatory standpoint, homeowners in California are not required to provide dedicated parking for an ADU, and they are not required to live on the property in order to rent one out. ORO Coast Builders assists clients in obtaining the necessary permits as part of their service.

As a licensed and insured ADU builder, ORO Coast Builders is equipped to take on the full scope of an ADU or garage conversion project. Hiring a licensed contractor for this type of work is important — these are significant construction projects that require proper credentials and experience to complete correctly and safely.

ORO Coast Builders Reviews

"I was referred to Sahar through a good friend of mine who was really happy with her remodel. She told me he'd been working independently for a long time and recently started his own company. I met with a lot of people when trying to decide who to hire for our renovation. I ended up going with ORO coast builders for several reasons: the first impression was great....he was punctual and professional and I felt he really understood the vision we had for the house and yard. He also had some great ideas of his own. His quote was reasonable in comparison to the rest. He was honest from the beginning about things that would cost more but also helped explain ways we could save money by using his contractor's license to buy finished material at a lower price and offered to come choose everything with me if I needed him too. The process was fairly smooth...a few hiccups along the way regarding timeframe but that's to be expected with a renovation of this size. Ultimately we're really happy with the way everything turned out."
