Do I need permits to install solar panels on my home?

Permit anxiety stops a lot of people. The reality: in 2026, a standard residential install is permitted in 4-10 weeks. Here's what you need, ordered by type.

Small install (≤ 10 kW) grid-tied

• Building permit from your city/county (often online)
• Electrical permit
• Installer's plan set with structural and one-line diagrams
• Utility interconnection application
• HOA approval (if applicable; legally protected in 25+ US states)

Mid-size (10-100 kW)

Now you do need engineer-stamped plans and a construction permit. Process stretches to 8-16 weeks. The utility will require interconnection studies and a meter swap.

HOA / shared solar

Some HOAs require approval (in many states they can't block solar but can dictate aesthetics). You'll need a sharing coefficient for community solar. Otherwise the process mirrors a normal install but signed by the HOA board.

Exceptions everyone forgets

• Historic district / landmarks: heritage commission approval
• Asbestos shingles: mandatory removal by certified contractor first
• Condo / shared roof: notification required, but veto rare
• Setback rules from neighbour property line

Permit cost

Residential permitting costs $200-700 in the US, typically handled by the installer. Beware quotes that exclude permitting: you might get hit for $800-1,400 later.

If you'll DIY, first read installing solar yourself (DIY) and avoid the common mistakes.
