LA ADU Subpanel Requirements (2026 Code)
When adding an ADU in Los Angeles, proper subpanel sizing is critical for passing LADBS inspections and ensuring safe operation.
Key Requirements for ADU Subpanels
- ✓Minimum 100 Amp Capacity: Most modern ADUs with electric ranges and mini-split HVAC systems require a dedicated 100A subpanel.
- ✓Main Panel Upgrade (Often Required): If your existing house panel is only 100A, you will almost certainly need to upgrade it to 200A to support the additional load of the ADU.
- ✓Title 24 Compliance: California energy code requires high-efficacy lighting and, in many new constructions, readiness for EV charging.
- ✓Clearances: The subpanel must have 36 inches of clearance in front and cannot be installed in bathrooms or clothes closets.
