How Long Solar Permitting Actually Takes in the USA (by Region)
The panels take a week. The permits take three months. Here's what to expect, market by market.
Fast markets (30–45 days end-to-end)
Florida (most counties), Texas (deregulated ERCOT territory), Arizona (SolarAPP+ adoption), Nevada.
Middle (60–90 days)
Georgia, North Carolina, Tennessee, Ohio, Colorado, most of the Midwest.
Slow markets (120+ days)
Northeast (MA, NY, NJ, CT), most of California (though NEM 3.0 approvals moved fast in 2025), Hawaii.
What accelerates
- SolarAPP+ — an instant-permitting platform now live in 200+ jurisdictions.
- Pre-approved system designs for common building types.
- Utility-side interconnection studies started in parallel with permit filings.
What delays
- HOA architectural review (for scattered SFR portfolios).
- Roof structural letters from third-party engineers.
- Utility interconnection queues in constrained transformers.
