Buying Land in Cumberland County, Pennsylvania

Fastest-growing county, but still nearly half farmland

Cumberland County sits directly across the Susquehanna River from Harrisburg and is squarely part of the capital region's metro growth, and the county's own agricultural-preservation materials describe it in blunt terms: Cumberland is Pennsylvania's fastest-growing county. That's a genuinely different starting point from most counties in this project, closer in kind to Chester County's Philadelphia-suburb dynamic than to a PA Wilds forestry county. But the same county materials make a second point worth taking seriously: nearly 170,000 acres, or roughly 48% of the county's total land area, remains devoted to active farming despite that growth pressure -- a substantial, still-working agricultural base rather than a county that has already tipped fully toward suburban development.

The practical upshot for a buyer is that Cumberland County genuinely contains two different land markets, and figuring out which one applies to a specific parcel matters. Land along active growth corridors (the county's own planning materials specifically mention encouraging nonresidential growth along the Harrisburg Pike) will trade differently, and face more active rezoning and annexation-adjacent pressure, than land in the county's more rural western and southern townships. Neither picture describes the whole county -- confirm which dynamic applies to a specific target parcel before assuming either a suburban-growth story or a purely rural-farmland one.

Agricultural zoning: a real, structured tool in fourteen townships

Cumberland County's Agricultural Land Preservation Board, working with the Tri-County Regional Planning Commission, has helped fourteen townships adopt a standard Agricultural Zone that permits a limited number of small non-farm lots off a larger tract while keeping the bulk of it in agriculture. Separately, the county's Agricultural Conservation Easement (ACE) program has purchased permanent, recorded easements on over 25,000 acres across 230-plus farms as of a September 2025 milestone. See our dedicated farm-land page for Cumberland County for how the Ag Zone's subdivision math works, the ACE program's application deadline, and what to check on a specific parcel.

Regional planning and septic

Cumberland County is one of three counties -- along with Dauphin and Perry -- served by the Tri-County Regional Planning Commission (TCRPC), the federally designated Metropolitan Planning Organization for the Harrisburg region, which coordinates regional transportation and land-use planning across the tri-county area's 103 municipalities. Cumberland County also maintains its own separate county Planning Department (310 Allen Road, Suite 101, Carlisle; 717-240-5362), handling municipal zoning-map coordination, open space, and greenways -- a somewhat different structure than Dauphin and Perry Counties, whose planning commissions TCRPC supports more directly. Cumberland County is not among Pennsylvania's small list of counties running their own county health department, so onlot sewage disposal permitting follows the state's Act 537 default: a DEP-certified Sewage Enforcement Officer, serving the specific municipality, conducts or oversees soil testing and issues the permit.

Records

The Cumberland County Recorder of Deeds (1 Courthouse Square, 1st Floor, Carlisle, PA 17013; 717-240-6370) holds title records including any recorded ACE easements, the Assessment Office (1 North Courthouse Avenue; 717-240-6350) handles property valuation, and the county's Property Mapper (GIS) provides current ownership, boundaries, and land-use classification data.
