Adopted building code
The 2021 International Residential Code, as adopted by the State in the Pennsylvania Uniform Construction Code (UCC). 34 Pa. Code 403.21(a)(7) adopts "The 'International Residential Code of 2021,' except that:" followed by the State's list of exclusions and modifications, effective January 1, 2026 (55 Pa.B. 7701). None of the State's changes touches Chapter 9, Roof Assemblies, or Section R803, Roof Sheathing, so those apply as the International Code Council publishes them. Work on existing buildings is also pointed to the State's existing-building code: "The repair, alteration, change of occupancy, addition and relocation of existing buildings must comply with Chapter 34 of the 'International Building Code of 2021' or with the 'International Existing Building Code of 2021'" (34 Pa. Code 403.21(f)). The UCC is the minimum everywhere in the state: "no municipality may propose or enact any ordinance which is less than the minimum requirement of the Uniform Construction Code" (Pennsylvania Construction Code Act, Act 45 of 1999, section 503(b)). The Act also lists work it "shall not apply to", including "Alterations to residential buildings which do not make structural changes or changes to means of egress" or to "Repairs to residential buildings," in each case "except as might be required by ordinances" kept in force under section 303(b)(1) or adopted under section 503 (Act 45 section 104(b)(5) and (6); 34 Pa. Code 403.1(b)(8) and (9)). The Act defines a repair as "The reconstruction or renewal of any part of an existing building for the purpose of its maintenance." So whether the code's roofing rules reach a given house reroof depends on the municipality's own ordinances. Everything above is Pennsylvania state law, the same in every municipality. Locally, Franklin Park Borough administers the code itself: Section 99-1 of the Borough Code (Ordinance No. 530-04, April 21, 2004) says "The Borough hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," Section 212-2504 A says a permit is "issued by the Building Inspector/Zoning Officer in accordance with Pennsylvania Uniform Construction Code requirements," and the Borough's Building and Zoning Department, at 2344 W Ingomar Road, takes the applications. Chapter 99 adopts the code "as amended from time to time" and changes none of its roofing provisions, and neither the Borough's permit pages nor its application names a code edition.
Permit process
No Borough text read names reroofing as permit work or as exempt. Chapter 99, the Borough's Uniform Construction Code ordinance, names no roof work and adds no permit clause of its own; Section 99-5 keeps in force building code ordinances adopted on or before July 1, 1999 that equal or exceed the code, and names none. The zoning chapter says "No building or structure shall be erected, added to or structurally altered until a permit therefor has been issued" (Section 212-2504 A), and requires a zoning permit before a structure is "erected, constructed, reconstructed, altered, razed or removed" (Section 212-2502 A); neither names roof work, and this record does not decide whether that zoning permit reaches a reroof. The Building and Zoning Department's permit application page (read October 7, 2026), under "Do you need a permit?", says "Permits are generally required for all non-residential structure renovations, all residential renovations that alter the size or structural elements of an existing residential structure, all new construction," and lists grading, sheds, fences, pools, decks, signs and others; it does not name roofing either way, and adds "If you submit a permit application and a permit is not needed, you will be notified as such." The Borough's Application for Building and Zoning Permit (Rev. 9-19) offers "Repair, replacement" and "Roof Over Deck" and no reroofing box, and its fee resolution, Resolution No. 1405-2025 (adopted December 2025), sets building permit fees from square footage and construction cost, with a multiplier of 0.5 for "Alterations to Existing," and has no roofing line. Under state law, Act 45 section 104(b)(5) and (6) list "Alterations to residential buildings which do not make structural changes or changes to means of egress" and "Repairs to residential buildings" among work the Act does not apply to, "except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503," and 34 Pa. Code 403.62(c) says "A permit is not required for the exceptions listed in § 403.1(b) (relating to scope) and the following, if the work does not violate a law or ordinance." No Borough text read names reroofing as permit work or as exempt, so this record does not decide whether the Borough requires a permit for an ordinary reroof. Ask the Building and Zoning Department at 412-364-4115 before work starts. Applications are e-mailed to the department; it says applicants are notified within 7 to 10 business days and that "The person performing the work should be the person applying for, purchasing, and signing for the permit when issued." Fees are paid by cash or check when the permit is picked up. The office is open Monday through Friday from 8 am to 4:30 pm. Read for this answer: Chapter 99 of the Borough Code, Construction Code, Uniform, in full; Chapter 111, Fees; Sections 212-104 and 212-2502 to 212-2512 of the zoning chapter; every page of searches of the whole Borough Code for "roof," which found no permit provision naming roof work, and for "reroofing," which found none; the Building, Zoning and Fire Official, forms and permit application pages; the Application for Building and Zoning Permit; and the building, zoning and enactment pages of Resolution No. 1405-2025.
