How to Get an ADU Permit in California

Building an ADU (Accessory Dwelling Unit) in California is a smart way to maximize your property, whether for rental income, family living space, or home office expansion. But before you break ground, understanding the ADU permit process is crucial. At Fortune ADU, we make getting your ADU permit easy, fast, and compliant with all local regulations.

Why Do You Need an ADU Permit in California?

In California, every ADU construction project requires approval from local authorities. An ADU permit ensures that your unit meets the zoning requirements, building codes, and safety standards mandated by the state. Whether you’re building a detached ADU, garage conversion, or adding a second-story unit, securing the right permits for ADU construction is the 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 determining if your property is eligible for an Accessory Dwelling Unit. California laws have specific zoning requirements based on property size, location, and setbacks. Our team can help you navigate zoning regulations to ensure your ADU plans meet 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’ll need to submit your ADU permit application to your city or county’s planning department. The application includes your plans, property details, and other required documents. Our experienced team at Fortune ADU will assist you in submitting a complete and accurate application to avoid delays.

Step 4: Schedule Inspections and Address Modifications

After you submit your ADU application, inspections will be scheduled to ensure your project complies with all safety standards. If adjustments are needed, we’ll help you quickly modify your design to meet compliance and ensure your ADU is approved.

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.
