Cambridge, Minnesota — One-Year Moratorium on Data Center Construction Within City Limits, Adopted Partly to See Whether State Legislation Arrives First (2026)
Cambridge, MN · City of Cambridge, Minn. — one-year data center construction moratorium (2026)
- Status
- In effect
- Expires
- September 1, 2027
- Applies to
- Developers seeking to construct data centers within Cambridge city limits during the moratorium year
- Enforced by
- City of Cambridge / Cambridge City Council
The City of Cambridge placed a ONE-YEAR moratorium on the construction of data centers within its city limits. The sequence leading to it is worth recording because it is more deliberate than most: the council had PREVIOUSLY INSTRUCTED STAFF to do initial research into data centers specifically in order to determine WHETHER AN OFFICIAL MORATORIUM WAS NEEDED — and only adopted one after that preliminary work came back. Many jurisdictions in this dataset went the other way, adopting a pause first and researching afterwards, which is a defensible response to an imminent application but produces measures whose necessity was never established. During the moratorium, more extensive research will be performed leading up to crafting appropriate ordinances and city codes. One stated reason for the twelve-month term is a wait-and-see posture toward the legislature: 'It would be best to see if new legislation comes from the State in the next year.' That is the same reasoning Ottawa, Illinois gave for extending its moratorium into 2027 — the Illinois POWER Act had stalled — and that Utica, Michigan's city attorney gave for holding her draft ordinance until other communities decided. Twelve months is also Minnesota's statutory maximum for such a moratorium, as the development director in neighbouring Isanti told her own council; Cambridge sits in Isanti County, so the two cities are working the same problem a few miles apart.

Legal detail
City of Cambridge, Minn. (Isanti County) — ONE-YEAR MORATORIUM on the construction of data centers within city limits. PROCEDURAL SEQUENCE, which is more rigorous than the norm here: the council FIRST INSTRUCTED STAFF TO CONDUCT INITIAL RESEARCH into data centers TO DETERMINE WHETHER AN OFFICIAL MORATORIUM WAS NEEDED, and adopted one only after that preliminary work. Contrast the prevailing pattern in this dataset \u2014 adopt immediately, study afterwards \u2014 which is a rational response to an imminent filing (see Warrick County IN 180-day data center moratorium (2026), where the plan commission suspended its rules and commissioners met at 9 a.m. the next morning) but yields measures whose predicate was never independently established. DURING THE MORATORIUM: more extensive research leading to appropriate ordinances and city codes. STATED RATIONALE FOR THE TERM: a wait-and-see posture toward the legislature \u2014 'It would be best to see if new legislation comes from the State in the next year.' THIS IS A RECURRING INSTRUMENT CLASS IN THIS DATASET, distinct from a study pause: Ottawa IL data center moratorium extended to 2027 extended through 2027-08-25 expressly because the Illinois POWER Act STALLED and the city wants local rules to ALIGN with whatever the state passes; Utica MI data center moratorium extension (2026) records a city attorney holding her draft until other communities' decisions were available; Elma WA temporary ALPR moratorium (2026) defers to a state Attorney General model policy due 2027-07-01 in a different subject area. A municipality in this posture extends for as long as the state stays silent. STATUTORY CEILING: 12 months is the Minnesota maximum for a municipal interim ordinance, as stated on the record by the Community Development Director of NEIGHBOURING ISANTI (Isanti MN 12-month data center moratorium (2026)), which cut its own proposed 30-month moratorium to 12 for that reason \u2014 AND noted the accompanying condition that the city must be proving staff are actively drafting. Cambridge and Isanti are both in Isanti County and are working the same question within miles of each other. MINNESOTA COHORT: Carlton County MN 1-year data center moratorium (2026), Otsego MN one-year data center moratorium (2026), Pine County MN 12-month data center moratorium (2026), Isanti MN 12-month data center moratorium (2026), Inver Grove Heights MN data center moratorium amended under lawsuit (2026) and Six-month moratorium on data centers >350,000 sq ft (Minneapolis).
