Pro Tips from Experienced Contractors

Allow adequate lead time. Loudoun County requires 10 business days notice before scheduling inspections. Factor this into project timelines, especially for tenant improvement deadlines.

Payment method matters. Only check or money order accepted for permit fees. Do not show up with cash or credit card expecting to pay.

Permits are non-transferable. If ownership changes or facility moves, new permits are required. Build this into your service agreements for clients.

Register alarms separately. Fire Marshal permits and alarm registration through FARU are separate processes. Complete both to avoid response issues.

Keep current with code. The 2021 Virginia Fire Prevention Code went into effect January 2024. Ensure your designs comply with current requirements, not outdated references.
