If you’re a solar installer, you already know one thing: not every permitting office makes your life easy. Some Authorities Having Jurisdiction (AHJs) move lightning-fast, approving permits in just days. Others? They’re notorious for strict requirements, lengthy reviews, and endless back-and-forth emails.
But strict AHJs don’t have to mean lost time and frustrated customers. With the right preparation, you can get permits approved smoothly, even in tough jurisdictions.
In this article, we’ll look at the AHJs known for having stricter solar rules in the U.S. — and share actionable tips to help you navigate them like a pro.
Why Some AHJs Are Stricter Than Others
Not all AHJs apply the same rules, and that’s because local conditions and priorities differ. Here are the most common reasons you’ll run into tougher requirements:
- Safety concerns – Wildfire, hurricane, or earthquake zones add extra safety checks.
- Historic districts – Local preservation rules may limit how solar looks on rooftops.
- High population density – Big cities with more permit applications usually enforce stricter reviews to avoid mistakes.
- State-specific code adoption – Some states enforce stricter versions of the NEC (National Electrical Code) or their own local amendments.
Understanding why an AHJ is strict helps you prepare the right way.
