Chester County, Pennsylvania: Government Structure and Services

Chester County operates under a home rule charter form of county government, making it one of a small number of Pennsylvania counties to have adopted this structure, which grants expanded local legislative authority beyond the default second-class county framework. This page covers the county's governmental organization, the services it delivers to approximately 545,000 residents (U.S. Census Bureau, 2020 Decennial Census), the mechanisms through which those services reach constituents, and the jurisdictional boundaries that separate county authority from state and municipal functions.

Definition and scope

Chester County is one of Pennsylvania's original 3 counties, established in 1682 alongside Philadelphia and Bucks counties by William Penn. Under the Chester County Home Rule Charter, adopted in 1976, executive authority is vested in a 3-member Board of Commissioners rather than a single county executive, a structure that distinguishes it from home rule jurisdictions such as Allegheny County, which uses an elected county executive model. The Board of Commissioners functions simultaneously as the county's legislative and executive body, setting policy, approving budgets, and overseeing county departments.

The county seat is West Chester Borough. Chester County encompasses 756 square miles and contains 73 municipalities — 15 boroughs and 58 townships — each of which maintains its own independent governmental apparatus. The county itself does not govern municipalities; it provides regional services layered above local government.

County government in Chester County covers property assessment and taxation, court administration, elections management, public health services, human services, open space preservation, and infrastructure coordination. Services delivered exclusively at the municipal level — local zoning enforcement, borough ordinances, township road maintenance on non-state-designated roads — fall outside county authority.

This page does not address the full scope of Pennsylvania's state government structure or Commonwealth-level agencies, even where those agencies operate facilities or programs within Chester County's geographic boundaries.

How it works

County government operations in Chester County are organized into elected offices, appointed boards, and administrative departments.

Elected offices include:

  1. Board of Commissioners (3 members, 4-year staggered terms)
  2. Controller (independent fiscal oversight)
  3. Sheriff (law enforcement and court-related functions)
  4. District Attorney (criminal prosecution)
  5. Prothonotary (civil court records)
  6. Register of Wills (estate and probate records)
  7. Recorder of Deeds (real property records)
  8. Clerk of Courts (criminal court records)
  9. Treasurer (county funds management)
  10. Coroner (death investigation)

The Board of Commissioners approves the annual county budget, which in fiscal year 2023 exceeded $530 million (Chester County Controller's Office). The Controller performs independent audits of county expenditures and is not subordinate to the Commissioners, providing a structural check on fiscal operations.

The Chester County Court of Common Pleas serves as the county's trial court of general jurisdiction, operating under the supervision of the Pennsylvania Judicial Branch. Judges are elected to 10-year terms. The court handles civil litigation, criminal matters, family court, and orphans' court proceedings. Magisterial District Judges operate at the sub-county level within defined geographic districts.

Property assessment is administered by the Office of Assessment, which maintains records for all taxable parcels in the county. The assessed value of real property in Chester County, once determined, forms the base upon which municipal and school district millage rates are applied — each taxing body sets its own rate independently.

The Chester County Health Department (chesco.org/health) is an accredited local health department, one of fewer than 10 county-level health departments in Pennsylvania that hold national public health accreditation from the Public Health Accreditation Board (PHAB). This accreditation status distinguishes it from the majority of Pennsylvania counties, where the Pennsylvania Department of Health delivers public health services directly.

Common scenarios

Residents and businesses interact with Chester County government across a predictable set of service categories:

Property transactions: The Recorder of Deeds processes deed transfers and mortgage recordings. The Office of Assessment handles appeals when property owners contest assessed valuations, with formal appeal deadlines set annually. School districts and municipalities rely on accurate assessment rolls for tax levy calculations.

Court involvement: The District Attorney's Office (chesco.org/da) handles criminal prosecution for offenses occurring within Chester County. Civil disputes above the magisterial threshold are filed with the Prothonotary. The Register of Wills administers estate proceedings when a decedent was domiciled in Chester County at the time of death.

Permits and land use: Zoning authority rests with individual municipalities, not the county. Chester County Planning Commission (chesco.org/planning) provides regional planning analysis and reviews municipal comprehensive plans but does not issue local zoning permits.

Human services: The Chester County Department of Human Services administers programs funded through a combination of county appropriations, Pennsylvania state funds channeled through the Pennsylvania Department of Human Services, and federal pass-through allocations. Programs include mental health services, intellectual disability support, drug and alcohol treatment, aging services, and children and youth services.

Elections administration: The Chester County Voter Registration Office administers voter rolls and coordinates elections under standards set by the Pennsylvania Department of State. The county uses electronic poll books and vote-by-mail infrastructure consistent with Pennsylvania's Election Code, 25 Pa. C.S. § 101 et seq.

Decision boundaries

Determining which level of government handles a specific matter in Chester County requires distinguishing between four jurisdictional layers:

State vs. county: The Pennsylvania General Assembly sets the legal framework within which county government operates. State agencies such as the Pennsylvania Department of Transportation maintain state-designated roads within the county regardless of county boundaries. The Pennsylvania State Police provide primary law enforcement coverage in municipalities without their own police departments; the Chester County Sheriff does not function as a general patrol agency.

County vs. municipal: The county provides services that are regional in nature or legally assigned to county government by the Pennsylvania County Code or the Chester County Home Rule Charter. Zoning, local ordinance enforcement, and municipal road maintenance are municipal functions. A resident disputing a local zoning decision appeals through municipal channels and ultimately to the county Court of Common Pleas — not through the Board of Commissioners.

County vs. school district: Chester County's 12 public school districts are independent governmental entities. The county does not govern school operations, curriculum, or school-level budgets. The county's role is limited to property assessment and tax collection functions that affect school district revenues.

Chester County vs. adjacent counties: Chester County's authority stops at its geographic boundary. Residents of Delaware County, Montgomery County, Lancaster County, or Berks County — all of which border Chester County — interact with their own county governments for property, court, and human services matters. Cross-boundary service agreements exist in some areas (regional planning, emergency communications) but do not transfer jurisdictional authority.
