Herndon, VA Short-Term Rentals: Occupancy Limits (2026)

Occupancy limits for short-term rentals in Herndon derive from a combination of the Herndon Zoning Ordinance, the Virginia Uniform Statewide Building Code (USBC), and applicable fire code provisions. While Herndon may set specific numerical caps in its STR regulations, common Virginia practice limits overnight guests to two persons per bedroom plus two additional persons (e.g., a 3-bedroom home would allow up to 8 overnight guests). Some jurisdictions use a square-footage-per-occupant formula consistent with USBC Section R-3 residential standards. Daytime guest counts for events or gatherings may be further restricted, and many Virginia STR ordinances explicitly prohibit using STRs for weddings, parties, or commercial events. Fire safety requirements under the Virginia Statewide Fire Prevention Code govern maximum occupancy from a life-safety perspective, requiring adequate egress, smoke alarms in every sleeping room and on each floor, and carbon monoxide alarms where required. Operators must post maximum occupancy clearly in the unit and should include it in rental listings. Exceeding occupancy limits is a Zoning Ordinance violation subject to civil penalties and potential STR permit revocation. HOA rules may impose stricter occupancy or guest-count restrictions under the POAA.
