Two address checks come before the checklist
A Northern Virginia mailing address does not, by itself, identify the permit authority or the electric utility. Use the parcel address to verify the city, town, or county that reviews the work, then verify the serving utility by address on the account or utility service record. Do not infer Dominion Energy or NOVEC service from a city name.
Which local permit path applies?
The local authority reviews the scope assigned to it. Depending on the property and design, that can include building, electrical, structural, zoning, historic-district, or other reviews. HOA approval is a separate private requirement and is not a substitute for a permit.
| Address or place name | Official path to check | Do not assume |
|---|---|---|
| Fairfax County address | Fairfax County residential solar permit library | That every Fairfax mailing address is in the county |
| Fairfax City | City of Fairfax solar-installation checklist | That the county process applies inside the independent city |
| Town of Leesburg | Town of Leesburg home-improvement coordination plus the applicable Loudoun County solar-permit path | That a Leesburg mailing address settles every town/county review |
| Loudoun County | Loudoun County solar permits | That the Town of Leesburg process applies outside town limits |
| City of Alexandria | City of Alexandria permit requirements and solar guidance | That an Alexandria mailing address is inside the independent city; some are in Fairfax County |
| Arlington County | Arlington County solar permit requirements | That a neighboring jurisdiction's checklist applies |
| Prince William County / Woodbridge | Prince William County residential solar guidance after confirming the parcel jurisdiction | That Woodbridge as a mailing label alone identifies every authority |
Reviews that may apply to the property
Ask which building and electrical permits apply, whether structural documentation is required for the proposed attachment, and whether zoning, historic-district, or HOA review affects equipment placement. Requirements change and the accepted design controls the final list; an online checklist is not approval for a specific address.
Net metering and interconnection are utility decisions
Dominion Energy Virginia and NOVEC publish separate net-metering and interconnection paths. Verify the serving utility by address before using either path. The utility reviews the proposed generating equipment and service connection; the local permit authority reviews its assigned code and land-use scope.
Inspection approval is not permission to operate
A project can clear its required local inspection and still be waiting on the serving utility's permission to operate. Keep the milestones separate in the written proposal: application responsibility, permit approval, installation, local inspection, utility meter or account work when required, and written permission to operate. Do not energize the system as grid-connected generation before the required utility authorization.
Who this guide fits — and what it cannot decide
This guide fits Northern Virginia homeowners organizing a proposal or checking who owns each approval. It does not replace a parcel lookup, accepted construction documents, utility review, HOA rules, or project-specific professional advice. Recheck the official pages and the property record before relying on any requirement.

Frequently Asked Questions (4)
Is the permit authority always the electric utility?
No. The city, town, or county permit authority and the serving electric utility have separate roles. Verify both from the exact property address.
Does a passed solar inspection mean I can turn the system on?
Not necessarily. Local inspection approval and utility permission to operate are separate milestones. Wait for every authorization required for the address and system.
Is every Alexandria mailing address in the City of Alexandria?
No. Some Alexandria mailing addresses are in Fairfax County. Confirm the parcel jurisdiction before choosing a permit path.
Can I identify Dominion Energy or NOVEC from the city name?
No. Verify the serving utility by address using the account or official service information, then follow that utility's current interconnection path.
