Solar Permit Plan Sets
Texas.
254 Counties.
NEC 2023.
Texas has no statewide solar permitting process — every one of its 254 counties sets its own rules. Houston, Dallas, Austin, San Antonio, Fort Worth: each runs a different system, portal, and timeline. We know them all and deliver AHJ-ready plan sets in 24–48 hours.
No Two Texas AHJs Are the Same
Permit Design prepares Texas solar permit plan sets and permit drawings for solar installers, EPCs, and roofing companies across all 254 Texas counties. Texas is the second-largest solar market in the US — and the most fragmented for permitting. There is no statewide process, no uniform checklist, and no consistent NEC enforcement. Every city and county operates independently.
What passes in Austin can stall in Houston. What clears Dallas may fail in Irving. Gulf Coast installations in Harris, Galveston, and Nueces counties require hurricane-zone wind load engineering that inland projects don't. NEC 2023 is the Texas state electrical code, but local adoption varies — some municipalities still enforce NEC 2020. We build every Texas plan set to the adopted code version of your specific AHJ, not the statewide default.
We process 2,000–2,500 plan sets every month across Texas and all 50 states. If your Texas AHJ requests revisions — or if you need the SB 1202 third-party pathway — we handle it at no extra charge.

Texas Solar Permit NEC Edition by City — 2026
