Isanti MN 12-month data center moratorium (2026)
Isanti, Minnesota — City Council REDUCES Its Data Center Moratorium From a Proposed 30 Months to 12, Because Minnesota Law Caps It at One Year and Requires Proof That Staff Are Actively Drafting an Ordinance (2026)
Isanti, MN · City of Isanti, Minn. — 12-month data center moratorium (2026), reduced from a proposed 30 months to the statutory maximum

The Isanti City Council adjusted its data center moratorium DOWN from a discussed 30 months to 12 months, and the reason is the most useful thing in this entry. Community Development Director Stephanie Hillesheim told the council that TWELVE MONTHS IS THE MAXIMUM LENGTH such a moratorium may run under Minnesota law: 'I know we discussed 30 months or 18 months, but it's 12 months. That's the longest we are allowed to put the moratorium on for.' She added a second condition that is easy to overlook — 'We have to be proving staff is working on an ordinance and doing research on it.' So the statutory allowance is not merely a clock. It is conditional on the municipality actually doing the work the pause is supposed to buy time for, and a jurisdiction that adopts a moratorium and then does nothing may not be able to defend it even inside the twelve months. This is the third statutory ceiling recorded in this dataset from a municipal official's own statement on the record, after Wisconsin's twelve months plus one six-month extension and a Nevada city attorney's assessment that moratoriums are defensible for roughly twelve to eighteen months. Several entries here run longer than any of those figures — three-year Arkansas county pauses, an eighteen-month Sierra County New Mexico moratorium and an eighteen-month Cary North Carolina one — which makes the ceilings worth checking against each state's own enabling law rather than assuming a common practice.

Legal detail
City of Isanti, Minn. (Isanti County) — data center moratorium ADJUSTED DOWN from a discussed 30 MONTHS to 12 MONTHS, with the City Council unanimously approving the draft ordinance. THE STATUTORY CEILING IS THE SUBSTANCE OF THIS ENTRY. Community Development Director STEPHANIE HILLESHEIM advised the council: 'I know we discussed 30 months or 18 months, but it's 12 months. That's the longest we are allowed to put the moratorium on for' \u2014 and, critically, 'We have to be proving staff is working on an ordinance and doing research on it.' MINNESOTA'S INTERIM ORDINANCE AUTHORITY (Minn. Stat. \u00a7 462.355 subd. 4 for cities) permits an interim ordinance for up to one year while a comprehensive plan or official controls are being studied, prepared or adopted. THE SECOND CONDITION IS THE ONE PRACTITIONERS MISS: the allowance is contingent on the municipality ACTUALLY CONDUCTING THE STUDY. A moratorium adopted and then left idle is exposed even within its term, because the statutory predicate \u2014 that official controls are being prepared \u2014 fails. This is the THIRD statutory or practical ceiling recorded in this dataset from an official's own on-record statement: Bellevue WI 12-month data center moratorium (2026) (Wisconsin: 12 months plus one 6-month extension, per the village administrator) and Henderson NV rejects data center moratorium, pursues code changes (2026) (a city attorney's assessment that moratoriums are defensible for 12 to 18 months). MEASURES IN THIS DATASET EXCEEDING THOSE FIGURES, which should be checked against their own states' enabling law rather than assumed sound: Madison County AR three-year data center moratorium (2026) and four other Arkansas counties at THREE YEARS, Sierra County NM 18-month data center moratorium (2026) and Cottage Grove WI 18-month data center moratorium (2026) at 18 months, Cary NC 18-month data center moratorium (2026) at 18 months, and a reported FIVE-YEAR Independence County AR moratorium. Minnesota peers indexed here: Carlton County MN 1-year data center moratorium (2026), Otsego MN one-year data center moratorium (2026) (12 months plus a bounded 6-month extension, consistent with this ceiling), Inver Grove Heights MN data center moratorium amended under lawsuit (2026) and Six-month moratorium on data centers >350,000 sq ft (Minneapolis).
