What the state rules actually say
Pennsylvania's Uniform Construction Code (UCC) is enforced locally by each Bucks County township or borough; its latest update took effect January 1, 2026, according to Labor & Industry. The UCC administration rules (Chapter 403) exclude repairs to residential buildings, and alterations that make no structural change or egress change, unless a local ordinance requires otherwise. The Construction Code Act carries the same two exemptions.
The same rules then list what is not an ordinary repair. Three items matter for waterproofing:
- Cutting away a load-bearing wall or a portion of one, which can include a foundation wall.
- Removing or cutting any structural beam or load-bearing support.
- Adding or relocating any drainage, drain leader, sewer or similar piping, or electric wiring.
The same section requires a permit before anyone installs or alters an electrical or plumbing system the UCC regulates.
Sorting a waterproofing estimate line by line
Most proposals bundle several kinds of work. Ask the contractor to split the estimate so each line can be classified:
- Likely exempt repair: sealing or injecting a crack, a wall coating, patching or extending downspouts. Still ask if your township has its own rule.
- Likely permit: a new interior drain line, a new sump basin with new discharge piping, or a discharge pipe moved through the wall.
- Likely electrical permit: a new outlet or circuit for the pump. Bristol Township's Building & Planning Department says its electrical code requires inspections for all electrical work.
- Structural review: anything that cuts, braces or anchors a foundation wall. Ask whether the township wants an engineer's details.
- Separate approvals: exterior digging, grading and where the water ends up (see below).
Not sure whether you need interior drainage or exterior work in the first place? Read what each one does before you compare permit paths.
Why your township may add its own rules
The exemptions above all say "except as required by ordinances." Under section 503 of the Act, a township can adopt stricter rules, and many Bucks towns also kept older local amendments. That's why one township may require a permit for work another treats as exempt. Why permit rules differ from one Bucks County township to the next explains which towns kept amendments.
Where the water goes is its own question
Tying a sump or foundation drain into the house sewer line is commonly banned. The Northampton, Bucks County Municipal Authority says Northampton Township's Ordinance No. 492 prohibits connecting sump pumps and downspouts to sanitary sewers, with fines of up to $1,000 a day, and that discharge must go to a storm sewer or onto the lawn. Ask your township and sewer authority where your discharge may go before the pipe is placed, and see where a sump discharge line should send water in winter.
Exterior digging brings in grading rules
Bristol Township's Permits & Licenses page lists grading among its permit categories. It says a written erosion and sedimentation control plan is required for 5,000 square feet to under 1 acre of earth disturbance, and that some municipalities require Bucks County Conservation District review even below 5,000 square feet. Bensalem's applications page lists a combined building permit and alteration-of-land application and reminds residents to call 811 before digging.
Which office and how to apply
Start with the Bucks County municipalities directory and confirm your actual municipality; a Bristol mailing address can be Bristol Borough or Bristol Township (which office handles which). In Bensalem, the Building and Planning Department handles plan review, permits and inspections for structural, electrical, plumbing and mechanical work. Bristol Township takes applications through an online self-service portal.
The state rules let the building code official waive construction drawings when review isn't needed, and waive or modify the site plan for an alteration or repair. So send a one-page scope first: interior or exterior, where concrete or soil comes out, drain and pump locations, any new wiring, and the discharge point. Then ask: Is any of this an exempt repair here? Which building, electrical, plumbing or grading permits apply? Do you need an engineer's details?
Put permits in the contract
- Name who applies, pays the fees and schedules inspections.
- If the contractor says no permit is needed, get that in writing and confirm it with the township using the same scope.
- Don't cover a trench or close a wall before inspection. Bristol Township inspects in a rough and a final phase, asks for 48 hours' notice, and must approve any changes made during the work.
- Keep the permit, inspection results and final approval with the house records.
