Common questions
Can SolarPermitCheck give a final yes/no answer?
Only when the connected official source supports it. Otherwise SolarPermitCheck shows the official source route, confidence, and the facts still needing verification.
Why does the exact answer depend on local sources?
These records and rules are controlled by city, county, state, district, or agency systems. The same street address can cross a boundary that changes the final answer.
