Tips

Roof-mounted solar PV permits are all-in flat fee of $300 — this covers all plan review and inspection. For complete submittals received before 11:00 AM, permits are typically processed the same business day.
Use the county's specific file-naming conventions for solar submittals: APPL-FORM.pdf for the application, BLDG-PLAN.pdf for the building plan set (load calcs must be included in this file, not separate), and STRU-CALC.pdf for structural calculations (manufactured homes only).
All PDFs must be properly rotated, flattened, and optimized before upload for faster processing.
If modifying an already-issued solar permit, submit the Modification Form as MODI-FORM.pdf along with the modified Building Plan Set.
