How to Get an ADU Permit in California
Building an Accessory Dwelling Unit (ADU) in California is a smart way to maximize your property, whether for generating rental income, creating additional living space for family, or expanding your home office. Before you start construction, it's essential to understand the ADU permit process. At Fortune ADU, we simplify the process of obtaining your ADU permit, ensuring it is quick and compliant with all local regulations.
Why Do You Need an ADU Permit in California?
In California, all Accessory Dwelling Unit (ADU) construction projects must receive approval from local authorities. Obtaining an ADU permit ensures that your unit complies with zoning requirements, building codes, and safety standards set by the state. Whether you are constructing a detached ADU, converting a garage, or adding a second-story unit, securing the necessary permits for ADU construction is the crucial first step toward a successful project.
Steps to Get an ADU Permit in California


Step 1: Understand Local Zoning Laws
The first step in the ADU permit process is to determine if your property is eligible for an Accessory Dwelling Unit (ADU). California laws have specific zoning requirements that depend on factors such as property size, location, and setbacks. Our team can assist you in understanding these zoning regulations to ensure that your ADU plans comply with local criteria.
Step 2: Prepare Your ADU Design
Your ADU design plans must be detailed and compliant with California building codes. Whether it’s a garage conversion or a new structure, the design must meet safety and accessibility standards. Our ADU design experts at Fortune ADU can help you craft plans that are both functional and permit-ready.
Step 3: Submit Your ADU Permit Application
Once you have your design, you will need to submit your ADU permit application to the planning department of your city or county. This application includes your plans, property details, and other required documents. Our experienced team at Fortune ADU is here to help you submit a complete and accurate application to avoid any delays.
Step 4: Schedule Inspections and Address Modifications
After submitting your ADU application, we will schedule inspections to ensure that your project complies with all safety standards. If any adjustments are needed, we will assist you in modifying your design quickly to meet compliance and secure approval for your ADU.
Step 5: Receive Your ADU Permit
Once approved, you’ll receive your ADU permit and can begin construction on your project. With our comprehensive knowledge of California’s ADU laws, we ensure that your permit is processed smoothly and efficiently.

What Our Customers Say
Ever since the concept of ADU's started making its presence in San Diego, I had been interested in living and engaging in these compact spaces. I was so amazed with how much people can do with such a small footprint and really love the concept of living a simple, uncluttered life. In early 2021, I stumbled upon FORTUNE ADU and loved their approach to Design through Execution. The clarity given on zoning laws for allowance of ADU's allowed to leverage my investment property and build in my backyard. One of the best decisions ever made.
