A. Core County Responsibilities
Allegheny County’s government provides services that:
- Span multiple municipalities (regional in scope).
- Are required by Pennsylvania law to be county functions.
- Cannot be delivered effectively by small boroughs/townships.
Key County Jurisdiction Areas:
- Elections & Voter Registration
- Manages voter rolls, polling places, mail-in ballots, election certification.
- Judiciary & Courts
- Court of Common Pleas (criminal, civil, family, orphans).
- District judges (magisterial).
- Jury services and court administration.
- Law Enforcement & Corrections
- County Jail (pre-trial detainees, short sentences).
- Sheriff (court security, transport, evictions).
- District Attorney (criminal prosecutions).
- Medical Examiner (cause of death, forensic services).
- Public Health
- Allegheny County Health Department: restaurant inspections, air quality enforcement, disease surveillance, immunizations.
- Human Services
- Department of Human Services (DHS): child protection, foster care, homelessness, aging, intellectual disabilities, behavioral health.
- Transit & Mobility
- Oversight and funding of Pittsburgh Regional Transit (buses, light rail, inclines).
- Regional airport operations (via Airport Authority).
- Infrastructure & Parks
- County-owned bridges and roads.
- Nine county parks (e.g., North Park, South Park).
- Regional facilities like swimming pools, golf courses, ice rinks.
- Property Assessment & Taxation
- Maintains property assessment system for taxation by county, municipalities, and school districts.
B. Areas Primarily State Jurisdiction (with County Interaction)
- Prisons: State correctional institutions are outside Allegheny; county jail only handles short-term.
- State Police: Provide coverage where municipal police do not.
- Education: K–12 schools funded/regulated by state, though county supports via AIU3.
- Environmental Regulation: DEP sets statewide standards, ACHD enforces locally under delegated authority.
- Elections Law: State sets the rules; county administers.
C. Areas Primarily Municipal Jurisdiction (County Support Role)
- Policing: Local police forces in boroughs/townships; county has no general police force.
- Zoning & Land Use: Each municipality sets zoning ordinances.
- Trash & Recycling: Managed by individual municipalities or contracted providers.
- Local Parks & Recreation: Borough-level facilities separate from county parks.
D. Overlap & Shared Jurisdiction
- Public Transit: Funded by both county (sales tax) and state (operating assistance).
- Human Services: State funds programs, county DHS delivers them.
- Public Health: Federal and state funding (CDC, DOH) supports county enforcement.
- Elections: Federal protections (Voting Rights Act) + state law (Election Code) + county administration.
- Courts: State-controlled system, but county funds operations and facilities.
E. Jurisdictional Boundaries in Daily Life
- A restaurant inspection in Dormont = County Health Department.
- A police call in Dormont = Dormont Borough Police (not county).
- A child welfare case in Dormont = County DHS, funded partly by state.
- A property tax bill in Dormont = County assessment base, but collected by Dormont and Keystone Oaks School District.
- A vote cast in Dormont = County-run election, certified under state law, overseen by federal standards.
Summary
Allegheny County’s jurisdiction is regional and connective: it runs elections, courts, jail, health, human services, transit, and assessments. Municipalities handle neighborhood services (police, zoning, trash). The state sets the legal framework and funds major systems. The county is the middle layer — not as local as borough councils, not as overarching as Harrisburg, but the crucial coordinator ensuring services exist across 130 municipalities.
