# Iron Mountain Data Center VA-4

PJM data center · https://askthegrid.com/assets/facilities/iron-mountain-data-center-va-4

Iron Mountain Data Center VA-4 is an operating data-center building at 11600 Hayden Road in Manassas, Virginia, within PJM. Prince William County's Build Out Analysis records the building as completed with 182,032 square feet of gross floor area. This profile distinguishes that county-reported building area from facility power or IT load and keeps building-specific facts separate from Iron Mountain's wider Manassas campus claims.

## Data quality

- Official and county records identify the exact asset as Iron Mountain Data Center VA-4 at 11600 Hayden Road. The county record lists it as completed in 2024, with permit BLD2023-03506 finaled, a June 11, 2025 occupancy date, and 182,032 square feet of county-reported building-permit gross floor area.
- Most available reporting concerns the wider Iron Mountain Manassas campus or other phases, especially the separate VA 8/9 expansion. Those sources are not treated as VA-4-specific evidence.
- No exact-site public-hearing record, named community organization, petition, or litigation was identified in the cited material. The Iron Mountain Manassas Point campaign is kept separate because its record identifies case REZ2024-00001 but does not identify VA-4 or 11600 Hayden Road.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
