Why the county can't just tell you
Montgomery County has 62 municipalities, and the county notes that most of them make land use and zoning decisions on their own. Building permits work the same way: Pennsylvania's construction code law lets each municipality enforce the code with its own staff, hire certified code officials or a third-party agency to act for it, share enforcement with neighboring municipalities, or contract with another municipality (Construction Code Act, section 501). So two houses a mile apart can have different offices, forms, fees and inspectors.
Step 1: confirm which municipality you're in
The town in your mailing address isn't proof on its own. The county directory lists look-alike pairs such as Hatfield Borough and Hatfield Township, plus long runs of Upper, Lower, East and West municipalities with similar names.
The county's property records search looks up assessment records by street address or parcel number (it stopped allowing searches by owner name in 2022). The record shows the municipality the parcel is in.
Step 2: find the code office and how it's run
Open your municipality from the county directory and look for pages called building permits, code enforcement, or community development. If that's unclear, call the municipal office and ask who the Building Code Official is.
The state keeps a backup: the Department of Labor and Industry's municipal elections and contact list shows every Pennsylvania municipality by county, its status under the Uniform Construction Code (UCC), and the name and phone number of its Building Code Official. L&I warns that some municipalities don't keep their contact entry current, so a blank or stale line doesn't mean nobody handles permits.
That list also tells you something the township website may not say plainly:
- "Opt-in" municipalities enforce the UCC themselves, sometimes through an outside inspection firm working on their behalf. You apply to the municipality, and it assigns the inspector.
- "Opt-out" municipalities have given up UCC enforcement. For residential work, L&I says enforcement goes to a certified third-party agency hired by the property owner, so you or your contractor would line one up.
- An "Amendments" note means the municipality kept local building rules from before July 1, 1999. L&I has no record of what they are, so only that municipality can tell you.
Step 3: describe the job, then ask specific questions
"Does a repair need a permit?" gets a vague answer. Instead, say what's being repaired or replaced, where it is, whether any size or location changes, and whether electrical, plumbing, heating or structural parts are involved. Then ask:
- Does a permit apply to this scope, and is there a separate zoning or trade permit?
- Who should apply, me or the contractor, and what drawings or product sheets do you need?
- Who does the inspections, and how do I schedule them?
- What's the fee, and what closes out the permit when the work is done?
Permit fees vary by municipality, but every UCC permit carries a $4 state surcharge on top of the local fee (Construction Code Act, section 703). Get the answer by email if you can, and if your contractor later changes the scope, send the new description back to the office rather than relying on the first answer.
For examples of how one municipality's rules look in practice, see our guides to Abington Township permits for roofs, fences and decks and finishing a basement in Upper Dublin. If you're thinking about pulling the permit yourself, this Bucks County guide covers the questions to ask, and they apply here too.
Looking for an old permit instead
If you're buying a house or chasing an earlier repair, permit and zoning records sit with the municipality, not the county. The state Office of Open Records lists the municipality or township where the property is located as the place to request them; deeds go to the county Recorder of Deeds. A county assessment record helps you find the right municipality but isn't a permit history.
