Buying Land in Delaware County, Pennsylvania

County seat Media, immediately southwest of Philadelphia. Delaware County packs Pennsylvania's fifth-largest county population into its third-smallest county land area -- a density of roughly 3,130 people per square mile -- and this page treats that honestly rather than forcing a rural land-buying narrative onto a fully built-out Philadelphia suburb. Here is the county's actual government structure, its municipality-by-municipality zoning, and what land buying realistically looks like here.

This Is Not a Rural or Raw-Land Market

Case-by-case / verify locally

With roughly 576,830 residents packed into the third-smallest land area of any Pennsylvania county, Delaware County is essentially fully developed. If you're looking for acreage-scale rural land -- a farm parcel, a wooded homestead lot, raw land to build a single-family home on from scratch -- Delaware County is not that market at any price point. What's actually available is infill lots, teardown-and-rebuild parcels, and small in-fill subdivisions within existing municipalities.

Home-Rule County Council, Not a Board of Commissioners

Generally favorable

Delaware County was the first county in Pennsylvania to adopt a Home Rule Charter (approved 1975, effective January 1976), replacing the traditional three-member Board of County Commissioners with a five-member, at-large County Council. County government here is structured differently from the standard PA county pattern described on our Pennsylvania overview -- confirm which office actually handles a given question before assuming a "commissioners" title applies.

Zoning Is Entirely Municipal -- No County Code

Case-by-case / verify locally

Delaware County has no zoning ordinance of its own. Every one of the county's roughly 49 boroughs and townships adopts and enforces its own separate zoning code under the state Municipalities Planning Code. In a county this densely built out, that typically means decades-old, fully mapped zoning rather than the unzoned rural townships you'd find elsewhere in Pennsylvania -- but it still means the specific municipality, not the county, is who to call.

Why this page does not pretend Delaware County is a rural-land market

This site exists to help people evaluate rural and semi-rural land, and most Pennsylvania counties fit that frame -- Delaware County genuinely does not. It is the Philadelphia region's original inner-ring suburb, bordering Philadelphia itself along the Delaware River and Chester waterfront, and its 2020 Census population of 576,830 makes it Pennsylvania's fifth-most-populous county even though it is simultaneously the state's third-smallest county by land area. That combination produces a population density of roughly 3,130 people per square mile -- among the highest of any county in the state outside Philadelphia itself. Forcing a conventional "here's how to evaluate raw acreage" narrative onto that reality would be misleading, so this page follows the honest-framing precedent this project has already applied to other fully built-out counties: describe the county's actual government and land-use structure plainly, and be direct that this is not a raw-land-buying market in the traditional sense.

What does exist here, for anyone still looking at Delaware County property, is a market in infill lots, teardown parcels, and small subdivided building lots inside the county's existing boroughs and townships -- Media, Swarthmore, Chester, Upper Darby, Radnor, and dozens more, each with its own dense residential fabric already in place. A buyer evaluating a Delaware County parcel should expect to be dealing with an established municipal zoning district, existing utility connections, and a built environment on every side, not open acreage.

Government structure: a home-rule County Council, not commissioners

Delaware County was the first county in Pennsylvania to adopt a Home Rule Charter, approved by county voters in a May 1975 referendum and effective January 1976. That charter replaced the county's former three-member Board of County Commissioners with a County Council -- expanded to its current five at-large, staggered-term members in January 1978. Council holds broad authority under the charter to legislate through ordinances and resolutions, set budgets, and oversee county departments across areas including land use, economic development, public transportation, and human services, with day-to-day department operations run by a Council-appointed Executive Director. This is a materially different structure from the standard Pennsylvania county pattern described on our state overview page, where a three-member Board of County Commissioners is the norm -- worth knowing before you go looking for "the commissioners" here.

Practically, this means county-level questions in Delaware County route through County Council and its appointed departments rather than an elected three-person Board of Commissioners, though the underlying divisions of labor -- a Recorder of Deeds for title records, an assessment office for property valuation, a planning department for countywide coordination -- still exist in familiar form even under the home-rule structure.

Zoning and permitting: entirely a municipal matter

Consistent with the Pennsylvania Municipalities Planning Code's statewide default, Delaware County itself has adopted no zoning ordinance of its own. Zoning authority rests entirely with the county's approximately 49 individual boroughs and townships, each of which maintains its own zoning map, zoning officer, and permitting process. Unlike the more rural Pennsylvania counties in this project, where a meaningful share of townships have never adopted any zoning ordinance at all, Delaware County's municipalities are, as a practical matter of the county's built-out, suburban history, essentially all long since zoned and mapped -- but the zoning district, permitted uses, and setback rules still vary building-lot by building-lot depending on which specific municipality a parcel sits in, so confirm directly with that municipality's own zoning office rather than assuming a countywide rule.

Septic is a minor factor here relative to most of this project's coverage: the overwhelming majority of Delaware County is served by public sewer given its urbanized, high-density character, so a Sewage Enforcement Officer and onlot (septic) permitting under the state's Act 537 framework would only realistically come into play for the rare unsewered parcel, if one exists at all in a given municipality -- confirm with that specific municipality whether public sewer serves a given address before assuming a septic system is even a live consideration.

What we could and couldn't confirm

Delaware County's FIPS code (42045) is independently confirmed via geocod.io's GEOID listing. Its status as the first Pennsylvania county to adopt Home Rule (1975 referendum, effective January 1976) and its current five-member County Council structure are drawn from the county's own government-structure page. Population (576,830), rank (fifth-most-populous, third-smallest by area), and density (roughly 3,130/sq mi) are drawn from Census Bureau QuickFacts and Wikipedia's cited figures. This page did not independently re-verify the exact current count of the county's municipalities (approximately 49) against a live county roster, and treats that figure as a stable, well-known reference. The characterization of Delaware County as having essentially no rural land market follows this project's own established precedent for other fully built-out, highly urbanized counties (Cook County, IL; Milwaukee County, WI; St. Louis City, MO) rather than a claim unique to this research pass.
