Data Center Zoning in Washington County, TN (2025-2026)

Washington County and its largest city, Johnson City, took two different but converging routes to the same worry in 2025-2026: keeping data centers and crypto-mining operations from landing on land that isn't zoned or resourced for them. The county passed two separate moratorium actions; the city rewrote its zoning code to confine the use to heavy industrial districts. Here's what actually happened, and what it means if you're evaluating land anywhere near this fight.

This page covers what's specific to Washington County. For the general explanation, see the national guide.

The county's two-step moratorium

Washington County's governing body moved on data centers in two separate actions during 2026. First, the County Commission passed a resolution -- approved by a 13-2 vote, effective immediately -- forbidding the construction, operation, and permitting of data centers, including cryptocurrency-mining operations, through June 30, 2027. Search-indexed coverage of this vote carries an inconsistent date (some sources point to late March 2026, others to early June 2026), and this research pass could not resolve which is correct against a primary county record -- confirm the exact adoption date directly with the Washington County Clerk's office if it matters to your timeline. Second, and more recently, the Washington County Board of Commissioners approved a further, separate one-year moratorium at its August 20, 2026 regular meeting, this one specifically halting the county's acceptance, processing, review, and approval of new applications for data centers and large-scale data-processing facilities in unincorporated county territory.

The practical upshot for a land buyer: as of this page's last review, unincorporated Washington County is under an active, dated moratorium on new data-center and large-scale data-processing-facility applications, layered on top of the earlier construction/operation/permitting ban running through mid-2027. Both of these are temporary by design -- moratoria, not permanent zoning-code amendments -- so the county's longer-term regulatory answer (a formal zoning-ordinance amendment, an outright ban, or something else) is still an open question. If your land-use plans have anything to do with large-scale computing, server, or crypto-mining infrastructure, confirm current moratorium status and any expiration or replacement action directly with the county before proceeding.

Johnson City's answer: heavy-industrial-only, not a ban

Johnson City -- the county's largest city and, geographically, the area where most large-scale development pressure actually concentrates -- took a different approach from the county's moratorium route. The city's Board of Commissioners adopted Ordinance No. 4914-25, which added "Data Centers" as a newly defined use category to the Johnson City Zoning Ordinance and confined that use to the I-2 Heavy Industrial District specifically, subject to additional development criteria, rather than banning the use citywide. The ordinance amended Article II (Definitions) and Article VI (Use Requirements by District), Sections 6.19, 6.20, and 6.22. It received first-reading approval on May 1, 2025, and was adopted on third and final reading June 5, 2025 -- meaning Johnson City's data-center rule has been in force for over a year as of this page's last review, longer-standing and more legally settled than the county's newer moratorium actions.

For a buyer, the district-by-district distinction matters: land inside Johnson City zoned anything other than I-2 Heavy Industrial cannot host a data center under the city's own code, full stop, regardless of what the county is doing in unincorporated territory nearby. Conversely, a genuinely I-2-zoned parcel inside city limits is one of the only paths in the immediate area where a data-center use is affirmatively, currently permitted -- worth knowing whether you're trying to attract that kind of development or trying to avoid living next to it.

A documented, unusually intense public backlash

This isn't a quiet regulatory adjustment -- the public opposition behind it is itself well documented. A City of Johnson City survey on the prospect of a data center in the city drew over 5,000 responses describing residents as "extremely concerned," out of roughly 6,000 total respondents -- a strikingly lopsided result for a municipal survey. Residents also turned out to speak against data-center development at the June 9 Johnson City Regional Planning Commission meeting. This tracks a broader Tri-Cities and East Tennessee regional pattern: several large data-center projects have been proposed or are under discussion within roughly 200 miles across Tennessee, Virginia, and Kentucky, and other regional jurisdictions have taken similarly restrictive stances -- neighboring Hawkins County banned crypto-mining operations outright and was subsequently sued by a crypto company (ExoticRidge) over that ban, a case still working through the courts as of this page's last review and worth watching as a signal of how enforceable these local restrictions ultimately prove to be.

For a land buyer, the honest takeaway is that Washington County's data-center rules are genuinely in flux and shaped by active, vocal community opposition -- not a settled, longstanding zoning category the way most land uses are. Whatever the county's rules say on paper the week you're reading this, that framework could look different within the moratorium's stated timeframe (mid-2027) or sooner if a formal ordinance replaces it, or if litigation like Hawkins County's plays out in a way that changes what local governments can actually enforce. Treat any data-center-adjacent land use here -- whether you're trying to develop one or trying to make sure your neighbor can't -- as requiring a fresh, direct check with the county and, if applicable, Johnson City's Development Services, rather than relying on this page's snapshot.
