Roofing in West Chester, Pennsylvania

Required

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, West Chester Borough administers the code itself: Section 43-2 of the Borough Code says "The Borough hereby elects to administer and enforce the Act and the regulations promulgated under the Act," Section 43-6 says the building code "shall be administered and enforced by the Department of Building, Housing and Codes Enforcement," and that department, at Borough Hall, 401 East Gay Street, West Chester, says its work "involves reviewing and issuing construction permits" and that it "coordinates with third party inspectors." Chapter 43 changes nothing in the code's roofing provisions. Section 43-2 adopts the "International Building Code, 2003 Edition, (IBC 2003) as now and as hereafter supplemented, reissued, amended and revised and its successor building codes," while the department's residential application instructions say "Borough of West Chester has adopted all 2021 IRC-Residential Codes effective January 1, 2026"; this record has not read the 2003 edition's text.

Whether a reroof on a West Chester house needs a permit is not stated by the Borough. The department's Building Permits page (read October 7, 2026) says "In West Chester, Building Permits are required for most construction and renovation projects to ensure compliance with safety and building code regulations" and lists a Residential Addition-Alteration-Repair application, whose instructions list additions, renovations, demolitions, systems work and "Miscellaneous residential (fireplace, pools, decks, etc.)" and do not name roofing. The Borough's Fee Schedule (adopted August 19, 2026) prices building permits for "New Construction, Alterations, Additions, Demolition, Signs & HVAC" by project value and has no roofing line. None of the department's pages says whether a reroof needs a permit. Chapter 43 of the Borough Code names no roof work either way. Section 43-7.C, among the provisions in effect on July 1, 1999 that the Borough keeps in force, says "All repairs and alterations to residential buildings shall comply with the Borough's building code adopted on April 21, 2004, and any successor code adopted by the Borough pursuant to Act 45 of 1999"; it does not use the word permit, and this record does not decide whether it requires one for a reroof. Section 43-4 deletes two of the regulation's permit exemptions, for uncovered decks ("Section 403.62(c)(1)(xvii)") and for windows in the Historic District Overlay ("Section 403.62(c)(1)(x)"); those subsections are cited at an earlier numbering of the state regulation. Under state law, Act 45 says the Act "shall not apply to" "Alterations to residential buildings which do not make structural changes or changes to means of egress, except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503" or to "Repairs to residential buildings, except as might be required by ordinances in effect pursuant to section 303(b)(1) or adopted pursuant to section 503" (section 104(b)(5) and (6)), 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." Before starting a reroof, ask the department, at 610-696-1773 (office hours 8am to 4pm), whether it treats the job as permit work; applications are filed through the Borough's online portal, SmartGov. The Fee Schedule lists a "Fine for working without a permit or expired permit" of "Double Permit Fee," and Section 43-3 makes building "in violation of an approved plan or directive of the Codes Enforcement Officer or of a permit" a summary offense "punishable by a fine of not less than $100 nor more than $1,000 per day." Properties in the Historic District come before the Historical & Architectural Review Board, which advises Borough Council on applications to "demolish, renovate and alter buildings" there. Read for this answer: Chapter 43 of the Borough Code, Building Construction (Sections 43-1 to 43-7), in full; a search of the whole Borough Code for "roof," which finds no permit provision naming roof work, and for "reroofing," which finds none; the Building, Housing and Codes Enforcement and Building Permits pages, the residential application instructions and the permit portal; the Historical & Architectural Review Board page; and the Fee Schedule adopted August 19, 2026.
