About NorCal ADU Builders

NorCal ADU Builders: A Full-Service ADU Contractor

NorCal ADU Builders is a California-based company that positions itself as a one-stop shop for accessory dwelling unit construction. From initial planning through to final inspections, they handle the full scope of an ADU project. Whether someone is looking to build a detached ADU, convert a garage, or add a backyard cottage to their property, NorCal ADU Builders aims to cover all the necessary steps under one roof.

Their process begins well before any construction starts. The planning phase includes developing detailed blueprints, liaising with the local building department, and submitting plans for approval. They have an in-house design team that can work from a client's existing ideas or help develop new ones. For certain locations, city pre-approved plans may also be available, which can help streamline the permitting process. Citrus Heights is one example of an area where such pre-approved options exist.

As part of the planning process, NorCal ADU Builders also handles Title 24 compliance — a requirement for all new buildings in California. They take care of the associated paperwork, which can be a complex part of the ADU building process for many property owners.

Construction Services

Once planning is complete, NorCal ADU Builders manages the full construction process. Their team works through each phase of the build, covering a broad range of trades and tasks. The construction scope they handle includes:

  1. Foundation work
  2. Sewer lateral
  3. Framing
  4. Roofing and gutters
  5. Rough electrical and rough plumbing
  6. Insulation and drywall
  7. ADU siding
  8. Bathroom tile
  9. Finishes including cabinets, paint, appliances, and flooring

By managing all of these elements in-house, NorCal ADU Builders aims to reduce the coordination burden on the property owner. As an ADU builder handling both structural and finish work, they serve clients who want a single point of contact throughout the project rather than managing multiple contractors separately.

Interior Design and Finish Selection

For clients who are uncertain about interior finishes or how to bring the design together, NorCal ADU Builders offers interior design services. Their team can assist with decisions around floor colors, cabinet styles, hardware, and other finish details. This service is intended to help clients make cohesive choices without having to navigate those decisions alone.

This is particularly useful for those building a granny flat, in-law suite, or Casita, where the interior finish quality can significantly affect both livability and rental value. Having design support available as part of the overall service offering means clients can address both the structural and aesthetic aspects of their ADU with the same team.

NorCal ADU Builders operates with a focus on thorough planning and consistent execution across all phases of the build. For property owners in Northern California looking for an ADU contractor that manages the process from start to finish, they present themselves as a capable option worth considering.
