Zoning in Butler County, OH: Data Centers, County vs. Township

Most Ohio counties' zoning split between county and township authority is a settled, static fact you just have to look up. In Butler County in 2026, that split actually played out live around a single hot-button issue -- data centers -- with two different, simultaneous outcomes depending on which side of the county line you're on.

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

The county's own zoning covers six townships, and they asked for a moratorium

Butler County has adopted county rural zoning under ORC Chapter 303, but it only applies in six of the county's thirteen townships: Hanover, Lemon, Madison, Milford, Oxford, and Ross. Every one of those six townships approached the Board of County Commissioners in 2026 and asked the board to consider a temporary ban on data-center development within their boundaries -- a notable detail in itself, since it shows the request for restriction came from the local township level up to the county, not the other way around.

The commissioners voted unanimously on June 16, 2026 to adopt a six-month moratorium, effective June 17 and running through roughly December 2026, prohibiting "the approval, establishment, or construction or the granting/issuance of any permit for any data center" within the six county-zoned townships. Commissioner Don Dixon framed the pause around infrastructure capacity, saying the county needed to understand "what we're committing our residents to, and the county's infrastructure, and the county's resources as far as water and sewer availability," while Commission President T.C. Rogers pointed to unanswered questions from developers as a driving factor.

Liberty Township, self-zoned, chose a different tool for the same problem

Liberty Township is not one of the six county-zoned townships -- it administers its own separate zoning under ORC Chapter 519, entirely independent of the county's moratorium. Facing the same underlying data-center development pressure, Liberty Township's Zoning Commission took a meaningfully different approach: rather than recommending an outright ban, it advanced a zoning change requiring any data-center project to go through the township's planned-unit-development (PUD) process, which requires a public hearing and a final vote by the township trustees before a project can move forward. Liberty Township's trustees adopted that change on a 3-0 vote in July 2026.

The practical difference matters: the county's approach in its six zoned townships was a temporary, blanket prohibition with a defined expiration date, while Liberty Township's approach doesn't ban data centers at all -- it just requires each proposal to clear a discretionary, case-by-case public review before trustees decide whether, and under what conditions, it can proceed. A developer (or a landowner considering a lease with one) would face genuinely different processes and timelines in Liberty Township versus one of the six county-zoned townships.

What this means for a buyer or landowner in Butler County

First, confirm which zoning system actually covers your parcel -- county (Hanover, Lemon, Madison, Milford, Oxford, or Ross Township) or a self-zoned township like Liberty, Fairfield, Morgan, St. Clair, Wayne, or West Chester -- since that alone determines which office, which ordinance, and which current data-center rules (if any) apply. Second, if you're specifically evaluating land for a data-center lease or sale, or land near a proposed site, ask directly whether the county's moratorium is still in effect (it was set to expire around December 2026) or whether it's been extended, replaced with a permanent ordinance, or allowed to lapse -- moratoriums like this one are, by design, temporary placeholders while permanent rules get worked out.

Third, recognize that this episode is a useful signal about how actively both the county and its townships are willing to use their zoning authority when a large-scale use shows up unexpectedly -- both the county-zoned townships and self-zoned Liberty Township moved quickly and decisively in 2026, which suggests a buyer with plans for any large-scale or unusual use in Butler County should expect real local engagement and possible pushback, not a rubber-stamp process.
