Who is responsible for getting solar permits — me or the installer?

Your installer typically handles the permit application process as part of their service, since they're familiar with the specific requirements of your local building department. Confirm this is included in your contract, as it should be standard for a full-service installer.

What happens if my system fails inspection?

Your installer addresses whatever issue the inspector identified and schedules a re-inspection — this is a normal part of the process and doesn't necessarily indicate a serious problem, though repeated failures are worth asking your installer to explain clearly.

Does permitting cost extra on top of my system price?

Permit fees are usually included in your overall quote, though they vary by municipality and are sometimes itemized separately on your invoice. Ask your installer to confirm whether permit fees are included in the quoted price or billed separately.

Solar Permitting and Inspection: What to Expect

Permitting and inspection are the least visible parts of going solar — but they exist for good reason, and understanding the process helps set realistic expectations for your timeline.

Why solar requires permits at all

Solar installations involve both structural work (mounting hardware attached to your roof) and electrical work (connecting a new power source to your home’s electrical system), both of which are regulated by local building codes to ensure safety — for you, for future occupants of the home, and for utility workers who might interact with your system’s connection to the grid.

What a typical permit application includes

Structural plans showing how the racking attaches to your roof and confirming your roof can support the added weight
Electrical diagrams showing how the system connects to your home’s electrical panel and, ultimately, the grid
Equipment specifications for the panels, inverters, and other components being installed
Site plans showing panel placement, required fire code setbacks, and access pathways

Your installer typically prepares and submits this paperwork as part of their service — confirm this is included when reviewing your contract.

Why permitting timelines vary so much by city

Some municipalities have adopted streamlined, solar-specific permitting processes (sometimes using standardized online portals) that can approve straightforward residential projects quickly. Others treat solar permits like any other construction permit, subject to the same queue and review times as unrelated projects, which can take considerably longer. This is genuinely outside your installer’s control — ask them directly what timeline they typically see in your specific city.

What happens during inspection

After installation, a local building inspector typically visits to confirm the work matches the approved permit and meets code requirements, commonly checking:

Proper mounting and structural attachment of the racking system
Correct electrical wiring, grounding, and disconnect switches
Appropriate labeling and signage required by code (important for firefighter and utility worker safety)
Adequate clearances and pathways on the roof per fire code

Utility interconnection: a separate approval step

Beyond your local building department’s inspection, your utility separately needs to approve the system’s connection to the grid — often involving a meter upgrade or reprogramming to handle two-way electricity flow for net metering. This is a distinct process from your city’s building inspection and follows your utility’s own timeline. See our installation process overview for how these steps sequence together.

What to do if something doesn’t pass inspection

It’s not unusual for an inspector to flag a specific item that needs correction before final approval — this is a normal quality-control step, not necessarily a sign of a bigger problem. Your installer addresses the item and schedules a re-inspection. If you experience repeated failures or unclear explanations, it’s reasonable to ask your installer directly for a clear account of what’s happening and why.

Bottom line

Permitting and inspection exist to keep your installation safe and code-compliant, and the timeline for these steps depends heavily on your specific city and utility rather than your installer’s speed alone. A good installer will set realistic expectations for your local process upfront rather than promising a timeline they can’t control.
