One of the most important aspects of building an ADU in California is navigating the permitting process. Each local jurisdiction has its own zoning laws and building codes that must be followed when constructing an ADU. In this blog post, we'll discuss the important aspects of navigating the permitting process and ensuring that your ADU meets all applicable regulations.
The first step in navigating the permitting process is to research the zoning laws and building codes in your local jurisdiction. You'll need to determine whether ADUs are allowed in your area, what the size and height limitations are, and what the setback requirements are. You'll also need to determine whether your ADU will be considered a separate dwelling unit or an accessory structure.
Once you've determined the zoning laws and building codes in your local jurisdiction, you'll need to obtain the necessary permits. This will typically involve submitting plans and obtaining approvals from the local planning department and building department. You may also need to obtain permits for electrical, plumbing, and mechanical work.
It's important to work with a reputable contractor who is familiar with the permitting process in your local jurisdiction. A good contractor can help ensure that your ADU meets all applicable regulations and can guide you through the permitting process. GSS Design Build specializes in building and zoning throughout the Bay Area and has built many great relationships with local city governments.
If you're unsure about the permitting process in your local jurisdiction, be sure to consult with local officials or visit the California Building Officials website for more information.
