1. Introduction to ADUs in Los Angeles
An Accessory Dwelling Unit (ADU) is a secondary housing unit on a single-family residential lot. ADUs can be attached or detached from the primary residence and are often used as rental units, guest houses, or living spaces for family members.
In Los Angeles, recent changes in state and local laws have made it easier for homeowners to build ADUs. However, the permitting process can still be complex and time-consuming if not approached correctly.
2. Understanding the ADU Permitting Process
The Los Angeles Department of Building and Safety (LADBS) is responsible for issuing permits for ADUs. The permitting process involves several stages, including:
- Preliminary Research and Planning
- Application Submission
- Plan Check and Corrections
- Permit Issuance
- Inspections During Construction
- Final Approval and Certificate of Occupancy
Each stage has its own requirements and timelines, which we’ll explore in detail.
3. Pre-Permit Preparation
a. Feasibility Study
Before starting the permit application, conduct a feasibility study to ensure your property is eligible for an ADU. Consider factors like:
- Zoning Regulations
- Lot Size and Coverage
- Setback Requirements
- Parking Requirements
b. Design and Planning
Hire a licensed architect or designer to create detailed plans that comply with building codes and zoning laws. This includes:
- Architectural Plans
- Structural Calculations
- Site Plans
- Energy Calculations (Title 24 Reports)
c. Pre-Submittal Review (Optional)
You can request a pre-submittal meeting with LADBS to review your plans for compliance, which can help identify potential issues early.
Estimated Time: 2 to 4 weeks (varies based on your preparation and design process)
4. Submitting Your Permit Application
a. Online or In-Person Submission
LADBS offers both online and in-person permit submissions. Online submissions can be more convenient but may still require in-person visits for certain documents.
b. Required Documents

5. Plan Check and Review Stages
a. Initial Plan Check
A plan checker reviews your submitted plans for compliance with:

b. Corrections and Revisions

c. Inter-Departmental Reviews
Your plans may also be reviewed by other departments, such as:
- Planning Department
- Fire Department
- Public Works
Estimated Time:
- First Review: Approximately 4 to 6 weeks
- Subsequent Reviews: 2 to 4 weeks per resubmittal
Total Plan Check Duration: 6 to 12 weeks, depending on the number of revisions needed.
6. Common Factors Affecting Permit Timelines
