Essentials to Know When Building an ADU

Accessory Dwelling Units (ADUs) have increasingly gained popularity. When building your ADU, there are some important steps that you need to follow to ensure that you build a legal, safe, and functional space. We’ve compiled a list of things you should know when building your ADU.

Building an ADU begins with determining whether your property is suitable for an ADU. Factors of zoning regulations include the size, height, and location of the ADU. Once an ADU is determined as feasible on your property, the design can be completed and submitted to the city for approval. After getting the necessary permits, construction can begin.

Define your Goals
Once you have a clear understanding of the regulations, you need to define your goals for your ADU. Do you want to rent or use it as a guest house? Do you need a full kitchen or just a kitchenette? Do you want to create a private outdoor space or share it with the main house? A clear idea of your goals will help you design a space that meets your needs and budget.

Design and Permits
The next step is to design your ADU and obtain the necessary permits. We can connect you with an architect or designer that aligns with your style or select your own. The final design should include all the necessary living spaces, such as a bedroom, a bathroom, a kitchen, and a living area. Building codes must be addressed in your plan, accounting for insulation, ventilation, electrical, plumbing, and structural requirements. Once your design is ready, you must submit it to the permitting department and obtain a building permit.

The construction phase involves site preparation, foundation laying, framing, roofing, and installation of windows and doors. Following this, electricity, plumbing, and HVAC systems are installed. The final phases encompass interior finishing, including insulation, drywall, flooring, and painting, and exterior work, such as landscaping and driveway construction.

The Cost of Building an ADU
The cost of building an ADU varies depending on the unit’s size, location, and design. The price in the South Bay ranges from $300,000 to $700,000 depending on the size and site preparation specifics of your ADU. Building an ADU can be an excellent investment to customize your lifestyle with more livable space, increase your property value, or provide an avenue for additional income, especially if you plan to rent out the unit.
