Zoning in Warren County, Pennsylvania

Why Warren County has its own zoning ordinance at all

Pennsylvania's Municipalities Planning Code (MPC) generally treats zoning as a purely local, municipal decision -- a township or borough can adopt an ordinance or simply choose not to, and in counties with no zoning role of their own, land in a non-zoned municipality is effectively unzoned. Warren County took a different path. The MPC also allows a county to step in and adopt zoning that applies specifically within municipalities that haven't adopted their own, and Warren County has done exactly that: the Warren County Zoning Ordinance, originally adopted August 13, 2008 and most recently amended February 18, 2026, applies in the 12 of the county's 27 municipalities that have no separate municipal ordinance of their own. In the other 15 municipalities, that municipality's own zoning ordinance governs instead, and the county has no zoning role there at all.

The practical effect is that "who regulates zoning here" is not a rhetorical question in Warren County the way it often is elsewhere in rural Pennsylvania -- it has two genuinely different answers depending on which of the 27 municipalities a parcel sits in, and this page's own research (limited to WebSearch-indexed county documents rather than a direct pull of the ordinance's current municipality list) could not confirm the specific, current roster of which 12 municipalities fall under the county's own ordinance versus which 15 have their own. That list is confirmable directly with Warren County Planning & Zoning, and it is worth confirming before assuming either way for a specific parcel.

How the county-administered system actually works

Where the county ordinance applies, Warren County Planning & Zoning (204 Fourth Avenue, Warren; 814-728-3512 or 814-728-3514) is the office that issues zoning permits, not a township or borough zoning officer. The county's own Zoning Permit Application requires an appropriate fee (paid to "Warren County Planning & Zoning") along with a plot plan showing existing and proposed structures on an aerial photo of the parcel; a granted permit is valid for one calendar year from the date of issue, and construction must be completed before it expires. The county also publishes separate, district-specific application-instruction sheets -- for example, dedicated instructions for the county's "B" district and its "R-2" district, both updated as recently as March 2026 -- so the specific paperwork depends on which zoning district a parcel falls in, not just on the fact that county zoning applies.

Disputes and exceptions run through the county as well. Where a proposed setback or other dimensional requirement doesn't meet the ordinance's minimum, that requires a variance approved by the Warren County Zoning Hearing Board -- a distinct body from the City of Warren's own separate Zoning Hearing Board, which handles variances only within city limits under the city's own, separately adopted zoning ordinance (last replaced by City Council on May 20, 2024). A buyer should not assume a variance process, a zoning officer, or even a zoning map from one part of the county applies in another -- confirm which specific regime (county or municipal) governs a target parcel, and if it's the county ordinance, confirm the district and current fee schedule directly with Warren County Planning & Zoning before budgeting for a permit.

Subdivision review works on a similar, county-facing model

Warren County also administers its own Subdivision and Land Development Ordinance (SALDO, amended August 14, 2022), with a Minor Subdivision Application most recently revised December 29, 2025. Warren County's own Planning Commission reviews proposed subdivision and land-development plans, and (per Pennsylvania's Municipalities Planning Code, Act 247, governing planned developments) applications must comply with state procedural requirements on top of the county's own. Note that Warren County land-use governance runs through two related but distinct bodies with similar names in public records: the county's own Planning & Zoning office (which issues zoning permits and reviews subdivisions under the county SALDO) and the separate Warren-area City-County Planning Commission (warrenpc.org), which handles some regional planning and zoning-amendment functions and hosts its own fee schedules and application forms -- worth being precise about which office you're contacting for a specific question.
