THIRTY-EIGHT MUNICIPALITIES, FOUR OF THEM IN ONE WEEK, and the most of any state -- but read the count carefully. Stafford Township, Jackson Township, North Brunswick and East Brunswick all acted in the last week of August 2026, and New Jersey is approaching 40 municipal bans on data-centre construction. WHO IS COUNTING MATTERS, as it does for every tally on this site: the figure is kept by Climate Revolution Action Network New Jersey, an advocacy group that describes itself as the state's largest Gen-Z political organisation and that trains residents to pass these ordinances. It is the best count available and it is not a government register. THE LEGAL QUESTION UNDERNEATH THE NUMBER, raised by an opponent of data centres rather than a supporter: in New Jersey, as under most municipal land-use schemes, a use not specifically permitted is already prohibited. Jackson's own township counsel advised that data centres were therefore ALREADY barred everywhere in the township before any ban was passed, and the council president voted against the ordinance arguing that defining the use gives applicants' lawyers something to work with. If that reading is right, some share of these 38 ordinances are symbolic at best and counterproductive at worst -- and nobody counting bans is counting that distinction. NOT ESTABLISHED: no court has ruled, and the answer will differ by municipality depending on how each code is written. WHAT IS ALREADY BEING TESTED IS THE PRICE. Two developers have sued: Hexa Builders is seeking $300 MILLION from Monroe Township in Gloucester County over its April 2026 ban, now in federal court, and a developer sued Andover Township in Sussex County over its ban earlier. That is the same mechanism recorded on this map in Illinois, where a county's own attorney warned a moratorium invited suit and the moratorium died without a vote. In New Jersey the towns passed the bans anyway and the bill is arriving afterwards. WHAT WOULD SETTLE THE REAL QUESTION: how many of the 38 have been tested by an application or a suit. Thirty-six have not.
THE COUNT IS NOT AGREED, AND THE DISAGREEMENT IS BETWEEN ALLIES. On the night of Aug 25, 2026 two advocacy groups working TOGETHER on the same ordinances published incompatible totals. Climate Revolution Action Network called North Brunswick, East Brunswick and Stafford the 35th, 36th and 37th New Jersey municipalities to ban data centres, and Jackson the 38th the following night. At the East Brunswick meeting the same evening, Food & Water Watch's Charlie Kratovil told the council it was joining MORE THAN 50 other New Jersey communities. Both groups organised these ordinances side by side. The gap is at least fourteen towns. WHAT WOULD EXPLAIN IT is a definitional difference of the kind this map keeps running into -- whether a moratorium counts as a ban, whether a planning-board recommendation counts before the council votes, whether a town where the use was never permitted counts at all -- and neither group publishes its rule. A THIRD COUNT, from electricchoice.com, tracks 225 moratoriums across 30 states and puts Ohio first with 35, then Michigan 34, Georgia 24 and North Carolina 19, which would displace New Jersey from the top spot entirely; but that count is of MORATORIUMS, and New Jersey's claim is about outright BANS, so the two are not measuring the same thing. WE ARE NOT PICKING A NUMBER. This site records that the range runs from roughly 38 to more than 50 depending on who is counting, that no government register exists, and that anyone citing a single figure should say whose rule they are using.
THE ROSTER, AS PUBLISHED. CRAN's list of New Jersey municipalities with bans on the books, reported by Patch on Aug 20, 2026, named 33: Andover, Asbury Park, Bayonne, Berkeley Heights, Bernards, Burlington, Cherry Hill, Deerfield, Delanco, East Greenwich, Edgewater Park, Harrison, Holland, Holmdel, Howell, Jersey City, Logan Township, Mansfield, Medford, Millville, Monroe, Montgomery, Neptune, Pemberton, Red Bank, Sayreville, Sparta, Summit, Union, Vernon, Warren, Waterford and Winslow. Adding Stafford, North Brunswick and East Brunswick on Aug 25 gives 36, and Jackson on Aug 26 gives 37 -- while CRAN called Jackson the 38th. One municipality is unaccounted for in the published list, which is a further reason to treat any single figure as approximate. Cinnaminson and South Brunswick had ordinances awaiting second reading. THE STATE HAS NOT FOLLOWED THE TOWNS: in May 2026 Governor Mikie Sherrill announced a plan to REGULATE rather than ban, promising guardrails, transparency, investment in energy infrastructure and job standards, and positioning New Jersey to compete in AI. So the municipal wave and the state policy are pulling in different directions, which is the same split recorded in Michigan and now New York.
