Operational · 9A mapped building in OpenStreetMap, a Texas Comptroller program registration, or news reporting the site as running.
Under construction · 0News reporting construction underway at the site.
Planned · 1A TCEQ air permit on file with no mapped building yet, or a project announced in the news. Permits come before buildings, so this is the early-warning state.
Paused · 0News reporting the project on hold.
Inactive · 0News reporting the facility closed or the project cancelled.
Registered, status unknown · 2In a state registry under a program that says nothing about construction (no air permit, no mapped building). Unknown is the answer, not a guess.

How this registry is counted

One row is one campus. OpenStreetMap maps individual buildings, so buildings within 400 meters of each other fold into a single facility; a facility found by two sources within 400 meters of each other is one row that lists both. Coordinates are never altered — a merged row keeps the mapped building’s position.

Status is inferred from what each source states and nothing more: a mapped building or a Texas Comptroller registration means the facility exists; a TCEQ air permit with no building yet means it is permitted, not built; a registry entry under a non-air program says nothing about construction, and the row says so. No source here confirms anything on site.

State and county come from the U.S. Census TIGER/Line county boundaries the facility point falls inside. Every count on this page is computed from the same registry file — nothing is typed in by hand.

Questions

How many data centers are in Harris County, Texas?

As of the September 18, 2026 registry snapshot, Harris County has 12 facilities: 9 operational, 1 planned, 2 registered, status unknown. Named facilities include Cyrusone LLC - Houston West III Data Center, Data Foundry, HOCKLEY DATA CENTER, HOUSTON WEST DATA CENTER. Only facilities recorded by a public source Geolocity mirrors are counted.

Where do these rows come from?

Buildings tagged as data centers in OpenStreetMap, the Texas Comptroller's data-center program registry, and facilities registered as data centers in TCEQ's Central Registry. Each row links the record it came from. County placement uses U.S. Census TIGER/Line boundaries.

What does a data center near a parcel mean for the land?

Two things a landowner cannot see from the surface: demand for nearby land and competition for local water and power. The Geolocity parcel report shows every facility within 25 miles of a specific address alongside the aquifer beneath it and the county's industrial water use. This page is the public record; it is information, not advice.
