Summary
Installing solar energy equipment in Fairfax County requires a building permit from the Building Official, though the county charges no permit fee for the installation itself.
Solar energy: No permit fee shall be charged to install solar energy equipment, although a permit is required for such installations and the permit holder is subject to the re-inspection fee.24.Team inspections: A fee shall be paid for each inspection involving an application for a change in use, change in occupant or other special request which requires inspection by one or more of the following disciplines: Building, Electrical, Plumbing, Mechanical and/or the Fire Marshal.

The fee shall be based on a percentage of the estimated cost of the work. A fee per plan review discipline. (i.e., building, electrical, mechanical or plumbing) may be assessed for each resubmission of plans for alterations to existing commercial buildings.26.Temporary Structures: The fee for temporary structures includes, but is not limited to tents, produce stands and sales office trailers.

Full Breakdown
Fairfax County's fee schedule, Code Section 61-1-3(d)(23), lists solar energy equipment as a no-fee permit item but confirms a permit is still required for the installation. The permit holder remains subject to a re-inspection fee if a scheduled inspection is rejected because the work fails to meet applicable codes. Homeowners and installers must file for a building permit with the Department of Land Development Services before mounting rooftop or ground panels; skipping the permit exposes the installation to code-enforcement action even though the county charges nothing to file it.
Violations & Fines
Installing solar equipment without a building permit is unpermitted construction; the Building Official can issue a stop-work order and require the permit be obtained retroactively, plus applicable re-inspection fees.
