Do you need a building permit in Trainer, PA, and who issues it?

Yes. The Borough of Trainer adopted the Pennsylvania Uniform Construction Code as its municipal building code1. Anyone who intends to construct, enlarge, alter, repair, move or demolish a building, or change its occupancy, must first apply to the building official and obtain the permit2. Some residential and accessory work is exempt under § 80-5 of the borough code, so ask before assuming a small job needs nothing2.

Delaware County does not issue building permits; the county Planning Department sends building permit questions to the municipality's code enforcement officials10. Fees for building-code administration are set by Borough Council resolution11. Trainer's code office also posts a building permit application and a fee schedule on its page4.

Does Trainer have zoning, and what does it mean for lot size and height?

Yes. Trainer's Borough Council adopted a zoning chapter, Chapter 265, and uses and construction inside the borough are subject to it3. The borough is divided into zoning districts, and the official zoning map is on file at the borough office12.

Rules differ by district. In the R-1 Single-Family Residence District, every dwelling needs a lot of not less than 5,000 square feet7. Buildings may cover no more than 40% of an R-1 lot13, and R-1 buildings are limited to three stories or 25 feet, whichever is less8. Check your parcel's district on the borough zoning map before you rely on any of these numbers.

Do you need a zoning permit in Trainer, and what does it cost?

Yes, for most visible changes. Trainer's code enforcement page lists zoning permits as required for a new home, an addition, a deck, a new fence, a shed, an in-ground pool, a driveway, a porch enclosure and a new business, and states a cost of $50.00 residential and $100.00 commercial4. A certificate of zoning approval is also required before occupying or changing the use of land or a building that is erected or altered14.

An occupancy inspection by the Building Official is tied to that certificate15. Conditional uses, such as a mobile-home park in R-1, go through a separate conditional use application164.

How do septic permits work in Trainer?

Septic permits for Delaware County, including addresses in Trainer, are handled by the Delaware County Health Department under Pennsylvania Act 53717. A permit is required for new on-lot systems, repairs and modifications, and a permit is valid for 3 years from issuance5. New major permits require soil testing5.

We could not confirm whether the borough's own code adds septic rules or which Trainer properties sit on public sewer, so call the Delaware County Health Department before you buy a lot that is not clearly connected to a sewer17. Across Delaware County only a small share of soils rate as not limited for a conventional drain field, 3.6%, so expect a site evaluation18.

Can you live in an RV or tiny home in Trainer?

We could not confirm a borough rule on living in an RV, camping on private land or occupying a tiny home inside Trainer. Call the Trainer code enforcement and zoning officer before parking or building anything intended as a dwelling4.

One rule is clear: Trainer's zoning allows a mobile-home park only where Chapter 265 permits it, and in R-1 that is a conditional use16. That does not by itself permit an individual manufactured home outside a park16.

Building a home in Trainer: the steps, in order

  1. Find your parcel's zoning district on the borough's zoning map and confirm lot size, coverage and height limits12.
  2. Apply for a zoning permit and, if required, conditional use approval through the borough's code enforcement and zoning officer4.
  3. Apply to the Building Official for a Uniform Construction Code building permit before work starts2.
  4. If a subdivision or land development is involved, the Delaware County Subdivision and Land Development Regulations apply in the borough9.
  5. For any on-lot septic or private well, apply to the Delaware County Health Department17.
  6. Obtain the certificate of zoning approval before occupying14.

What stays with Delaware County, and what to check before you buy in Trainer?

The county decides septic and well permits56. Rules for land outside the borough differ, so see the Delaware County page for those. A driveway onto a state highway needs a Pennsylvania Department of Transportation permit19.

County-level numbers give context: Delaware County's effective property tax rate is 2%20, and the typical home is valued around $373,57521. Ask the borough office about floodplain rules, short-term rentals and accessory dwellings, which we could not confirm.

Watch-outs

  • Trainer's borough office hours are Monday through Friday, 8am - 4pm, so call ahead before visiting about permits22.
  • We could not confirm Trainer's rules on RV living, tiny homes, accessory dwellings, floodplain development or short-term rentals, so ask the code enforcement and zoning officer before you buy4.
  • Delaware County's Planning Department does not issue building permits, zoning approvals or septic permits, so do not start there10.
