Everything You Need to Know About the Permitting Process for ADUs in Los Angeles


Understanding the Permitting Process
Building an ADU in Los Angeles involves several key steps, from initial planning to final approval. Here's what you need to know:
Initial Research and Feasibility
Zoning and Property Information: The first step is to review the local zoning code and property information to determine if your property is eligible for an ADU. You can check zoning regulations on the Los Angeles Department of City Planning website.
Preliminary Consultation: Schedule a consultation with a 121 Design Build Inc. professional to discuss your project's feasibility and initial design ideas.
Design and Planning
Architectural Plans: Work with an architect or designer from 121 Design Build Inc. to create detailed plans for your ADU. These plans should comply with local building codes and zoning regulations.
Site Plan: Prepare a site plan that includes the location of the ADU, setbacks, and any existing structures on the property. Our design team can assist you in creating a compliant and efficient layout.
Submitting Permit Applications
Zoning Clearance: Submit your plans to the Los Angeles Department of Building and Safety (LADBS) for zoning clearance. This step ensures that your project complies with local zoning laws.
Building Permit: Once you have zoning clearance, apply for a building permit. This involves submitting detailed construction plans and specifications to LADBS for review.
Additional Permits: Depending on your project, you may also need permits for electrical, plumbing, and mechanical work. Our team can guide you through acquiring all necessary permits.
Plan Review and Approval
Plan Check: LADBS will review your submitted plans to ensure they meet all building codes and regulations. This process may involve multiple rounds of revisions and resubmissions.
Approval: Once your plans are approved, you will receive the necessary permits to begin construction.
Construction and Inspections
Construction: With permits in hand, you can start the construction of your ADU. Ensure that all work is performed according to the approved plans and building codes. 121 Design Build Inc. ensures high-quality construction that meets all standards.
Inspections: Schedule inspections with LADBS at various stages of construction to ensure compliance with building standards. Inspections typically include foundation, framing, electrical, plumbing, and final inspection.
Final Approval and Certificate of Occupancy
Final Inspection: After construction is complete, schedule a final inspection with LADBS. If the ADU passes the inspection, you will receive a Certificate of Occupancy.
Occupancy: Once you have the Certificate of Occupancy, your ADU is officially approved for use.
