About This Tool

The Permit Finder uses a decision tree built from permit requirements across all 50 states, updated for 2025. It accounts for:

State-level code adoption (which NEC edition your state uses)
Rural vs. urban jurisdiction differences (including Texas SB 1252 rural exemptions)
Brand-specific documentation requirements (Enphase's extra interconnection step, Powerwall 3's integrated inverter documentation)
Solar vs. standalone battery differences in the permit process
States with unique requirements (Washington's dual state + local permit system, New Jersey's subcode system, Hawaii's PE-stamp requirements)
