Building permits in Delaware County, Pennsylvania come from the municipality or its authorized code official, not county government, and construction is subject to Pennsylvania's Uniform Construction Code12. Zoning requirements also depend on the township, borough or city where the parcel lies34. Delaware County Health Department handles on-lot sewage inspections, permit issuance and enforcement, as well as permits for private well construction56.

Do you need a building permit in Delaware County, Pennsylvania?

Yes. Construction in Delaware County is regulated by Pennsylvania's Uniform Construction Code, and building permits are administered by the municipality or another authorized building code official rather than by county government12. The Delaware County Planning Department directs building-permit questions to the municipality's code enforcement officials11. A UCC permit must normally be obtained before work starts, although an emergency repair or equipment replacement may begin if the permit application reaches the building code official within three business days2. A UCC-regulated residence cannot be used or occupied until a certificate of occupancy follows a compliant final inspection; the certificate must ordinarily be issued within five business days8. A qualifying agricultural building used for farm storage or animals and containing no habitable space is excluded from the state Construction Code Act, but municipal land-use, fire, electrical, health and environmental rules can still apply10.

Who issues Delaware County building permits, and how do you reach the county?

The code enforcement office for the parcel's township, borough or city is the first stop for a Delaware County building permit1. The Delaware County Planning Department does not issue the building permit; it performs advisory subdivision and land-development review and processes the county portion of Act 537 sewage planning modules11. The Planning Department can be reached at 610-891-5200 or at 2 W. Baltimore Avenue, Suite 202, Media, PA 1906311. If you do not know the correct municipality, Delaware County's general information line is 610-891-4000 at 201 West Front Street, Media, PA 1906312. Permit fees for ordinary construction are set locally, while the county publishes a separate fee schedule for its subdivision and land-development review13.

Does Delaware County have zoning?

Zoning decisions in Delaware County are made at the municipal level, so the controlling district, setbacks, minimum lot size, lot coverage and building height depend on the parcel's township, borough or city34. Delaware County publishes an interactive view of municipal zoning districts, including overlay districts that must be switched on in the map layers, but the county warns that its documents can become outdated and recommends confirming current zoning with municipal officials7. Subdivision is a separate review: Delaware County's subdivision and land-development ordinance governs twenty-one of the county's forty-nine municipalities and applies where a municipality has not enacted its own ordinance; plans still need municipal approval before recording9. County review applications may be filed online, by mailed PDF or in person, and physical submissions require three plan sets14.

How do septic permits work in Delaware County?

Delaware County Health Department is responsible for inspections, investigations, permit issuance and enforcement for on-lot sewage systems under Act 5375. The Delaware County Planning Department has a narrower role: it processes the county planning-agency portion of sewage-facility planning modules11. State law generally requires an on-lot sewage permit before installing or using a building served by an individual or community system15. An owner or immediate-family residence on a qualifying contiguous tract of at least ten acres may be exempt, but only when the ownership, notice, local-ordinance and siting conditions are met15. No part of a system may be covered before its final inspection5. Site feasibility deserves early attention because only 3.6% of county soils are rated without severe limitations for a conventional septic drain field16.

Can you live in an RV or tiny home on land in Delaware County?

We could not confirm one countywide rule allowing residential RV use, temporary camping or tiny-home occupancy on private land in Delaware County. Those land-use questions should go to the parcel's township, borough or city because zoning requirements are handled locally34. Pennsylvania's limits for RV stays in state park campgrounds do not answer whether an RV may be occupied on private property17. A federally labeled manufactured home installed exactly to its approved design has limited treatment under the UCC, but site work, utility connections, additions, repairs, relocation and some occupancy changes can still trigger the code; that state rule does not override local zoning or septic approval18. A composting or incinerating toilet also does not eliminate sewage planning: a new residence needs an approved way to handle washwater or excess liquid19.

Building a home in Delaware County: the steps, in order

  1. Identify the parcel's township, borough or city, then ask its code enforcement office about the zoning district, setbacks and building-permit submission31.
  2. Use the county zoning map as a starting point, but confirm its current district and overlays with the municipality7.
  3. If the project divides land or qualifies as land development, determine which subdivision ordinance applies and obtain municipal approval as well as county review9.
  4. For on-lot sewage, contact Delaware County Health Department for permitting and inspection requirements; do not cover any part before final inspection5.
  5. For a private well, obtain the county Health Department's construction permit and required written approval to use the well6.
  6. Obtain the UCC building permit before starting covered work, complete inspections and secure the certificate of occupancy before moving in28.
  7. If access touches state highway land or a PennDOT drainage facility, obtain a PennDOT Highway Occupancy Permit20.

What should you check before buying land in Delaware County?

Confirm the municipality, zoning district and every overlay directly with municipal officials before treating the county's interactive zoning map as current7. For a parcel relying on septic, investigate soils before closing because only 3.6% of county soils are rated without severe limitations for a conventional drain field16. A private well needs a Delaware County Health Department construction permit, followed by written approval supported by completion and water-quality information6. Development within a Special Flood Hazard Area needs a municipal floodplain-development permit before work begins21. If subdivision or land development is contemplated, budget separately for municipal fees and county review fees; the county's residential review fee starts at $150 per plan plus $10 per lot or unit13. Delaware County's median property-tax bill is about $6,001 a year at an effective rate of about 2%2223.

Watch-outs

  • Do not rely on the county zoning map alone: its documents can become outdated, and municipal officials are the source for the current district and overlays7.
  • A Delaware County well-construction permit is required even though Pennsylvania separately exempts a homeowner drilling on owned or leased land from the commercial driller licensing requirement624.
  • We could not confirm a countywide owner-builder exemption; ask the parcel's municipal code enforcement office before assuming that doing the work yourself changes permit or inspection requirements11.
