Grant County, Indiana adopted a 24-month moratorium on data center permits on March 16, 2026 — one of the earliest and longest-duration county moratoria in the Indiana data center wave of 2026. Ordinance No. 4-2026 halts issuance of improvement-location permits and related applications for structures connected to data centers in unincorporated areas of the county. It remains in effect for 24 months or until the Area Plan Commission recommends a zoning amendment addressing data centers, whichever comes first. County Attorney Marty Harker drafted the ordinance, noting that the Grant County Zoning Ordinance had never addressed data centers — a code-silence problem common to many rural Indiana counties. Grant County's seat is the city of Marion (a different Marion from Marion County, which is Indianapolis).
Who is protected: Unincorporated Grant County, IN residents from unregulated large data center development during the moratorium period while the Area Plan Commission develops zoning standards
Legal detail
Grant County, Indiana — Ordinance No. 4-2026, adopted by the Board of Commissioners on March 16, 2026 (initial vote March 2, 2026; official signing March 16). INSTRUMENT: 24-month moratorium halting issuance or receipt of improvement-location permits and related applications for structures connected to data centers in unincorporated Grant County, Indiana. TRIGGER: code-silence — the Grant County Zoning Ordinance had not addressed data centers as a use class prior to this ordinance. DURATION: 24 months from adoption (expires approx. March 16, 2028) OR until the Grant County Area Plan Commission completes a study and recommends a zoning ordinance amendment addressing data centers, whichever occurs first. GEOGRAPHIC SCOPE: unincorporated Grant County (excludes incorporated cities and towns including county seat Marion, IN). DRAFTING: County Attorney Marty Harker; Commissioner Ron Stewart (District 3) moved initial vote. STRENGTH: moderate — 24-month duration exceeds most Indiana county moratoria (typical range: 6-12 months), but is still a permit pause rather than a permanent standard. INDIANA CONTEXT: as of July 2026, Indiana University's Environmental Resilience Institute counted at least 17 Indiana counties with temporary moratoriums and 11 with data center ordinances; Grant County is among the earlier adopters (March vs. summer 2026 wave). Grant County is in north-central Indiana; county seat is Marion, IN (not the same as Marion County/Indianapolis).
