About The Sterling-Watson Collective and ADU Construction in Los Angeles

The Sterling-Watson Collective is a full-service ADU contractor based in Los Angeles, offering a comprehensive range of construction services for accessory dwelling units. Their team includes structural engineers, architects, designers, and general contractors, all working together to manage ADU projects from initial design through to completion.

Accessory Dwelling Units (ADUs) are becoming an increasingly common solution for homeowners looking to add housing options on their existing property. An ADU is a small residential unit — either attached to or separate from the main home — located on the same lot. In a city like Los Angeles, where housing demand remains high, ADUs offer a practical way to increase density and provide additional living space.

Common uses for an ADU include:

  1. A rental unit to generate supplemental income
  2. Accommodation for extended family or guests
  3. A home office or creative studio
  4. A granny flat or in-law suite
  5. Independent living space for older children

ADUs in Los Angeles typically range from around 400 to 1,200 square feet, and any live-in unit requires a building permit. Most residential properties in Los Angeles County can support some type of ADU, though local zoning regulations will determine what is permissible on a given lot.

The Process of Building an ADU with The Sterling-Watson Collective

Building an accessory dwelling unit in Los Angeles involves several steps, and navigating them requires careful planning and knowledge of local regulations. The Sterling-Watson Collective manages this process on behalf of their clients, handling each phase of the project.

  1. Understanding local zoning laws: Before any construction begins, it is important to understand the zoning regulations and restrictions that apply to the property. The Sterling-Watson Collective assists clients in identifying what is permitted in their specific area.
  2. Design and planning: Their in-house architects and designers work with clients to develop plans that meet both personal requirements and local building codes. This includes detailed construction documents and 3D renderings of the finished ADU.
  3. Permitting and approvals: The team handles the necessary permit applications and coordinates with city agencies to obtain the required approvals before construction begins.
  4. Construction management: As licensed general contractors, The Sterling-Watson Collective oversees all aspects of the build, including hiring and managing subcontractors, ordering materials, and scheduling work. Quality control is maintained throughout the construction process.
  5. Finishing touches: Once the main construction is complete, the team assists with interior finishing decisions and any additional elements needed to complete the space.
  6. Certificate of Inspection: Before an ADU can be occupied, a Certificate of Inspection must be obtained from the local building department. The Sterling-Watson Collective ensures all work meets the required standards so this process proceeds without issue.
