THE BUILDING PROCESS

FLOOR PLAN DESIGN & APPROVAL

The floor plan design process for building an Accessory Dwelling Unit (ADU) typically involves the following steps:

  1. Determine your needs and goals: The first step in designing an ADU is to determine your needs and goals. Consider your lifestyle, your family's needs, and any potential renters. Ask yourself what features are most important to you and what you want to achieve with your ADU.

  2. Assess the site and existing structures: Before designing your ADU, you'll need to assess the site and any existing structures on the property. This will help you determine the best location for the ADU and any design constraints that may need to be considered.

  3. Create a rough sketch of the floor plan: Once you have a clear understanding of your needs and the site constraints, you can begin creating a rough sketch of the floor plan. This can be done by hand or using design software.

  4. Refine the floor plan: After you have a rough sketch, it's time to refine the floor plan. Consider the flow of the space, the placement of windows and doors, and the overall aesthetics of the design. You may want to consult with an architect or designer at this stage to ensure that your design meets local building codes and zoning regulations.

  5. Finalize the floor plan: Once the design has been refined, you can finalize the floor plan. This includes creating a detailed floor plan that includes dimensions, placement of fixtures, and finishes.

PERMITTING

The permitting process for Accessory Dwelling Units (ADUs) in California can vary depending on the specific city or county regulations. However, in 2017, the state passed legislation that simplified and standardized the permitting process for ADUs to encourage the construction of these units to address the state's housing crisis.

Here is a general overview of the permitting process for ADUs in California:

  1. Check local regulations: Before starting the process, check the local regulations to determine if ADUs are allowed in your area, what types of ADUs are permitted (such as attached, detached, or converted units), and what size and design requirements are in place.

  2. Obtain a property survey: A property survey is required to identify the location and boundaries of the property, as well as any existing structures.

  3. Obtain design plans: You will need to obtain design plans that show the proposed ADU's size, location, and design. These plans must meet local building codes and regulations.

  4. Submit permit application: Once you have the property survey and design plans, you can submit a permit application to the local building department. The permit application will include the design plans, a fee, and other required documentation.

  5. Review and approval process: The building department will review the permit application to ensure it meets local regulations and building codes. They may request changes or additional information before approving the permit.

  6. Construction: Once the permit is approved, construction can begin on the ADU. You may need to obtain additional inspections and permits during the construction process to ensure the project meets all building codes and regulations.

The permitting process for ADUs in California is generally more streamlined and straightforward than it has been in the past, thanks to recent state legislation. However, it is still important to research local regulations and requirements to ensure a smooth and successful permitting process.

Construction Process

The construction process for an Accessory Dwelling Unit (ADU) can vary depending on factors such as the size and complexity of the project, the location of the property, and local regulations. However, here is a general overview of the steps involved in constructing an ADU:

  1. Site preparation: The first step in the construction process is to prepare the site. This may include clearing the land, grading the site, and installing any necessary utility connections.

  2. Foundation: Once the site is prepared, the next step is to construct the foundation for the ADU. This may involve pouring a concrete slab or installing a crawl space or basement.

  3. Framing: Once the foundation is in place, the next step is to construct the framing for the ADU. This involves building the walls, roof, and floor structures.

  4. Electrical and plumbing: With the framing in place, the next step is to install electrical and plumbing systems. This includes running wiring, installing plumbing fixtures, and connecting to the main utility lines.

  5. Insulation and drywall: Once the electrical and plumbing systems are installed, the next step is to insulate the walls, floors, and ceilings. This is followed by installing drywall and finishing the interior surfaces.

  6. Flooring, cabinets, and fixtures: After the walls and ceilings are finished, the next step is to install flooring, cabinets, and fixtures. This includes installing kitchen cabinets, bathroom fixtures, and any other interior finishes.

  7. Exterior finishes: With the interior finishes in place, the next step is to install exterior finishes such as siding, roofing, and windows. This is followed by landscaping and any necessary site improvements such as driveways or walkways.

  8. Final inspection: Once construction is complete, the ADU must undergo a final inspection to ensure that it meets all local building codes and zoning regulations.

The construction process for an ADU can take several months and requires careful planning and coordination to ensure that the project is completed on time and within budget. It's important to work with experienced professionals who can help guide you through the process and ensure that your ADU is built to the highest standards of quality and safety.
