Solar Permitting in Los Angeles: What Homeowners Need to Know
Every solar installation in Los Angeles County requires a building permit. The good news: California has streamlined solar permitting significantly in recent years, and your installer handles the entire process. The challenge: with 88 cities in LA County, each with its own building department, timelines and requirements vary widely.
At Anca Solar, we've pulled permits across every major LA County jurisdiction since 2000. Here's what to expect in 2026.
Why Do You Need a Permit for Solar?
Solar permits ensure your installation meets California's building, electrical, and fire codes. The permit process verifies:
Structural safety: Your roof can support the weight of solar panels
Electrical safety: Wiring, grounding, and connections meet National Electrical Code
Fire safety: Panels maintain required setbacks from roof edges and ridges for firefighter access
Wind resistance: Mounting systems can withstand local wind loads
Installing solar without a permit is illegal, can void your homeowner's insurance, and will prevent you from connecting to the grid for net metering.
Permit Costs by Jurisdiction
Solar permit fees in LA County range from $200 to $800 depending on the city. Some examples:
City of Los Angeles (LADBS): $250–$400 for standard residential solar. Express solar permits may have reduced fees.
Pasadena: $250–$500. Requires separate electrical permit.
Glendale: $300–$500. Building and electrical permits required.
Burbank: $200–$400.
Santa Monica: $250–$450.
Long Beach: $300–$500.
Beverly Hills: $350–$600.
Santa Clarita: $250–$450.
Unincorporated LA County: $300–$600.
Your installer typically includes permit fees in their quoted installation price. At Anca Solar, all permit costs are included in our proposals — no hidden fees.
Permit Timelines by City
How long it takes to get your solar permit approved varies significantly across LA County:
Fastest (3–7 Business Days)
City of Los Angeles: LADBS offers an express solar permit program for standard residential systems. Simple rooftop solar (no battery, no panel upgrade) can be approved in 3–5 days.
Santa Monica: Solar-friendly permitting, typically 3–7 days.
Pasadena: Efficient building department, 5–7 days for straightforward systems.
Moderate (1–3 Weeks)
Glendale: 7–15 business days. Requires dual building/electrical review.
Burbank: 5–10 business days.
Long Beach: 7–14 business days.
Santa Clarita: 7–10 business days.
Slower (2–4 Weeks)
Beverly Hills: 10–20 business days. More stringent review process.
Unincorporated LA County: 10–20 business days depending on complexity.
Any system requiring structural engineering review: Add 5–10 days.
Required Documents for Solar Permits
Your installer prepares and submits all of these:
Site plan: Aerial view showing panel placement, setbacks, and equipment locations
Roof plan: Panel layout with dimensions and mounting details
Electrical single-line diagram: How the solar system connects to your home's electrical panel
Structural calculations: Engineering analysis confirming roof can support panels
Equipment specifications: Data sheets for panels, inverters, racking, and batteries
Title 24 compliance: Energy code documentation
Fire setback plan: Showing required clearances per California Fire Code
California Fire Code Requirements
Solar panels must maintain specific setbacks on your roof to allow firefighter access:
Ridge setback: 3 feet from the roof ridge (ridge vent access)
Edge setbacks: 18 inches from roof edges (varies by jurisdiction)
Pathway requirements: 3-foot-wide pathways to provide firefighter access across the roof
Rapid shutdown: All systems must include module-level rapid shutdown capability (required since 2020 NEC)
These setbacks reduce your usable roof area. An experienced installer accounts for fire code requirements during the design phase so your quoted system size is accurate.
AB 2188: California's Solar Permitting Streamlining Law
California Assembly Bill 2188 requires all cities and counties to offer streamlined, expedited permitting for small residential solar systems. Key provisions:
Cities must provide a checklist-based review for qualifying systems
Applications meeting the checklist must be approved administratively (no planning commission review)
Cities must accept electronic applications
Permit fees must be based on actual costs, not arbitrary amounts
A qualifying system is rooftop solar on an existing single-family home that doesn't exceed the home's electrical service capacity. Most standard residential installations qualify.
Common Permitting Delays and How to Avoid Them
Plan Corrections
If the building department identifies issues with the submitted plans, they'll issue corrections. Common triggers:
Missing structural calculations
Insufficient fire setback documentation
Electrical load calculations showing need for panel upgrade
Incomplete equipment specs
An experienced installer rarely receives plan corrections because they know each jurisdiction's requirements. At Anca Solar, our correction rate is under 5%.
Main Panel Upgrade Required
If your home has a 100A or 125A electrical panel and the solar system (plus battery or EV charger) exceeds the panel's capacity, you'll need a 200A upgrade. This requires a separate electrical permit and adds 1–3 weeks plus $2,000–$4,000.
HOA Approval Delays
If you live in an HOA community, you may need architectural approval before or during the permitting process. California's Solar Rights Act limits HOA review to 45 days. Start this process early.
Historic District Requirements
Homes in designated historic districts (parts of Pasadena, Glendale, and Santa Monica) may need additional design review. This rarely prevents installation but can add time.
Online vs In-Person Permitting
Most LA County jurisdictions now offer online solar permit applications:
City of LA: Fully online through LADBS portal
Pasadena: Online application available
Santa Monica: Online through TRAKiT portal
Long Beach: Online through building department portal
Beverly Hills: Online and in-person
Online applications are generally faster and allow your installer to submit immediately after engineering is complete, without waiting for an in-person appointment.
Permitting for Battery Storage
Adding a battery storage system to your solar installation doesn't require a separate permit in most jurisdictions — it's included in the solar permit. However, batteries do add complexity to the electrical plans and may extend plan review time by a few days.
Battery installations must comply with additional fire code requirements, including clearances from electrical panels and HVAC equipment, and proper ventilation for certain battery chemistries.
Inspection After Installation
After your system is installed, your city schedules a final inspection. The inspector verifies:
System matches approved plans
All connections are properly made and grounded
Rapid shutdown system functions correctly
Fire setbacks are maintained
Equipment is properly labeled
Most inspections take 30–60 minutes. If the inspector identifies issues, your installer corrects them and schedules a re-inspection. At Anca Solar, we pass first inspection over 95% of the time.
