South Londonderry Township - Zoning, Building and Land Development

South Londonderry Township, at 27 West Market Street, Palmyra, in Lebanon County, takes building permit applications, with inspections and plan reviews done by two contracted agencies, Associated Building Inspections and Commonwealth Code Inspection Service. The Pennsylvania Uniform Construction Code applies statewide, but Act 45 section 104(b) lists "Repairs to residential buildings" and alterations that make no structural or egress change among work it 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."

Permit process note
No South Londonderry Township text read names reroofing as permit work or as exempt. The Township's Zoning, Building & Land Development page (read October 9, 2026) says "Permits are required to repair, construct, enlarge, alter, or demolish a building or structure," and that the Township "follows the Uniform Construction Code (UCC) as the standard for building, construction, remodeling, and repairs"; it names no roof work. The Commonwealth Code Inspection Service application lists the improvement types "New," "Addition," "Alteration," "Repair/Replacement," "Relocation" and "Other," and the Associated Building Inspections application lists "Alteration or Renovation" among its types; neither names roofing. Neither agency's 2025 residential fee schedule nor the Township's 2026 fee schedule has a roofing line. The Township's Uniform Construction Code ordinance was not read for this record: it is not among the ordinances posted on the Township's Ordinance Information page, and no online copy of the Township's code was found, so any permit or exemption section in it, and any older building ordinance it keeps in force, were not read. 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." The Township's statement names no roof work, no agency document read names reroofing as permit work or as exempt, and the Township's code could not be read, so this record does not decide whether the Township requires a permit for an ordinary reroof. Ask the Township office at 717-838-5556 before work starts. The Township's checklist says applications "will not be processed if the application is not properly completed and all appropriate documentation submitted," and a contractor doing the work must submit a certificate of workers' compensation insurance or a notarized exemption statement. The Township office is open Monday to Friday, 7:30 a.m. to 4:00 p.m. Read for this answer: the Township's Zoning, Building & Land Development, Ordinance Information and Hours & Phone Numbers pages; its building permit application checklist; the Commonwealth Code Inspection Service 2025 residential fee schedule (a scanned page, transcribed from the rendered page image) and residential application; the Associated Building Inspections 2025 fee schedule and permit application; the Township's 2026 fee schedule; and the Township's 2024 Zoning Ordinance, whose exemption for repairs and maintenance applies to the zoning permit only.
Adopted 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, South Londonderry Township administers the code through two inspection agencies under contract to it: its Zoning, Building & Land Development page says "An application for a permit is to be filed with the Township and no work shall commence until permit is issued" and that "building inspections and plan reviews are completed by a third party agency under contract to the Township. Associate Building Inspections, LLC (ABI) and Commonwealth Code Inspection Service (CCIS) are agents of the township," and the page posts each agency's fee schedule and permit application. The Township office is at 27 West Market Street, Palmyra. The Township's Uniform Construction Code ordinance was not read for this record: it is not among the ordinances posted on the Township's Ordinance Information page, and no online copy of the Township's code was found, so any permit or exemption section in it, and any older building ordinance it keeps in force, were not read. The Commonwealth Code Inspection Service application the Township posts says "Applicable Codes: 2009 IBC/IRC, 2012 IBC Chapter 11, 2009 ICC A11 7.1," and the Township's own pages name no edition; this record has not read the 2009 edition's text and does not decide which edition the Township applies.
Repair permit threshold
No South Londonderry Township text read names reroofing as permit work or as exempt. The Township's Zoning, Building & Land Development page (read October 9, 2026) says "Permits are required to repair, construct, enlarge, alter, or demolish a building or structure," and that the Township "follows the Uniform Construction Code (UCC) as the standard for building, construction, remodeling, and repairs"; it names no roof work. The Commonwealth Code Inspection Service application lists the improvement types "New," "Addition," "Alteration," "Repair/Replacement," "Relocation" and "Other," and the Associated Building Inspections application lists "Alteration or Renovation" among its types; neither names roofing. Neither agency's 2025 residential fee schedule nor the Township's 2026 fee schedule has a roofing line. The Township's Uniform Construction Code ordinance was not read for this record: it is not among the ordinances posted on the Township's Ordinance Information page, and no online copy of the Township's code was found, so any permit or exemption section in it, and any older building ordinance it keeps in force, were not read. 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." The Township's statement names no roof work, no agency document read names reroofing as permit work or as exempt, and the Township's code could not be read, so this record does not decide whether the Township requires a permit for an ordinary reroof. Ask the Township office at 717-838-5556 before work starts. State law sets no square-footage or percentage threshold for roof work; any threshold is set locally. The Uniform Construction Code "does not apply to" "Alterations to residential buildings which do not make structural changes or changes to means of egress, except as required by ordinances in effect under sections 303(b)(1) or 503 of the act" or to "Repairs to residential buildings, except as required by ordinances in effect under sections 303(b)(1) and 503 of the act" (34 Pa. Code 403.1(b)(8) and (9)), and "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" (34 Pa. Code 403.62(c)). For houses the regulation adds: "An ordinary repair does not require a permit." Its list of work that is not an ordinary repair names cutting away a load-bearing wall, "The removal or cutting of any structural beam or load-bearing support," changes to a required means of egress, and new or relocated piping, wiring or mechanical work (34 Pa. Code 403.62(d)); roofing is not named. A municipality may require more: under Act 45 section 503(c) it "may enact ordinances pursuant to this section which adopt additional code requirements for alterations or repairs to residential buildings," after a public hearing and after filing the proposed ordinance with the Department of Labor and Industry. These rules concern a "Residential building," which the regulation defines as "Detached one-family and two-family dwellings and townhouses which are not more than three stories above grade plane in height with a separate means of egress and their accessory structures" (34 Pa. Code 401.1). Everything above is Pennsylvania state law, the same in every municipality. Locally, South Londonderry Township administers the code through two inspection agencies under contract to it: its Zoning, Building & Land Development page says "An application for a permit is to be filed with the Township and no work shall commence until permit is issued" and that "building inspections and plan reviews are completed by a third party agency under contract to the Township. Associate Building Inspections, LLC (ABI) and Commonwealth Code Inspection Service (CCIS) are agents of the township," and the page posts each agency's fee schedule and permit application. The Township office is at 27 West Market Street, Palmyra. The Township's statement that permits are required to repair, construct, enlarge, alter or demolish a building sets no area, percentage or cost threshold.
Roof layer limit / recover
Two layers at most where the state code reaches the job. Pennsylvania adopts the 2021 International Residential Code without changing its reroofing section, R908 (34 Pa. Code 403.21(a)(7); the State's list of changes names no Chapter 9 section). Section R908.3.1.1 says "A roof recover shall not be permitted where any of the following conditions occur," and the third condition is "Where the existing roof has two or more applications of any type of roof covering." So one existing layer may be covered once, and a roof that already has two layers is torn off to the deck. The same section also bars a recover "Where the existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing" and "Where the existing roof covering is slate, clay, cement or asbestos-cement tile." The existing-building code the State also adopts, the 2021 International Existing Building Code (34 Pa. Code 403.21(f)), carries the same three conditions in Section 705.2.1.1. These rules bind work the Uniform Construction Code reaches. The Act does not apply to "Repairs to residential buildings" or to alterations that make no structural change, "except as might be required by ordinances" (Act 45 section 104(b)(5) and (6)), so whether R908 binds a particular house reroof turns on that exclusion and on the municipality's own ordinances. Everything above is Pennsylvania state law, the same in every municipality. Locally, South Londonderry Township administers the code through two inspection agencies under contract to it: its Zoning, Building & Land Development page says "An application for a permit is to be filed with the Township and no work shall commence until permit is issued" and that "building inspections and plan reviews are completed by a third party agency under contract to the Township. Associate Building Inspections, LLC (ABI) and Commonwealth Code Inspection Service (CCIS) are agents of the township," and the page posts each agency's fee schedule and permit application. The Township office is at 27 West Market Street, Palmyra. The Township's Uniform Construction Code ordinance was not read for this record: it is not among the ordinances posted on the Township's Ordinance Information page, and no online copy of the Township's code was found, so any permit or exemption section in it, and any older building ordinance it keeps in force, were not read. The Township's pages and the agencies' documents it posts say nothing on roof layers. The Commonwealth Code Inspection Service application the Township posts says "Applicable Codes: 2009 IBC/IRC, 2012 IBC Chapter 11, 2009 ICC A11 7.1," and the Township's own pages name no edition; the text above is the 2021 edition's, the 2009 edition's reroofing text was not read for this record, and this record does not decide which edition the Township applies.
Deck & sheathing requirements
State rules from the base code, where the state code reaches the job. Pennsylvania adopts the 2021 International Residential Code without changing Section R803, Roof Sheathing (34 Pa. Code 403.21(a)(7); the State's changes to Chapter 8 are to ridge framing and attic ventilation). Lumber roof sheathing follows Table R803.1: over rafters or beams 24 inches apart it must be at least 5/8 inch net thick. Wood structural panels "shall be identified for grade, bond classification and performance category by a grade mark or certificate of inspection issued by an approved agency," and their spans "shall not exceed the values set forth in Table R503.2.1.1(1) or APA E30." For shingles, "Asphalt shingles shall be fastened to solidly sheathed decks" (R905.2.1), and on any reroof "The structural roof components shall be capable of supporting the roof covering system and the material and equipment loads that will be encountered during installation of the roof covering system" (R908.2). These rules bind work the Uniform Construction Code reaches; the Act does not apply to "Repairs to residential buildings" or to alterations that make no structural change, "except as might be required by ordinances" (Act 45 section 104(b)(5) and (6)). Act 45 section 104(b)(5) excludes alterations "which do not make structural changes or changes to means of egress" and says only that "a structural change does not include a minor framing change needed to replace existing windows or doors"; 34 Pa. Code 403.62(d)(2) lists "The removal or cutting of any structural beam or load-bearing support" as not an ordinary repair. Neither names roof sheathing; this record does not decide whether replacing it is either. Everything above is Pennsylvania state law, the same in every municipality. Locally, South Londonderry Township administers the code through two inspection agencies under contract to it: its Zoning, Building & Land Development page says "An application for a permit is to be filed with the Township and no work shall commence until permit is issued" and that "building inspections and plan reviews are completed by a third party agency under contract to the Township. Associate Building Inspections, LLC (ABI) and Commonwealth Code Inspection Service (CCIS) are agents of the township," and the page posts each agency's fee schedule and permit application. The Township office is at 27 West Market Street, Palmyra. The Township's Uniform Construction Code ordinance was not read for this record: it is not among the ordinances posted on the Township's Ordinance Information page, and no online copy of the Township's code was found, so any permit or exemption section in it, and any older building ordinance it keeps in force, were not read. The Township's pages and the agencies' documents it posts draw no separate line for roof sheathing. The Commonwealth Code Inspection Service application the Township posts says "Applicable Codes: 2009 IBC/IRC, 2012 IBC Chapter 11, 2009 ICC A11 7.1," and the Township's own pages name no edition; the text above is the 2021 edition's, the 2009 edition's sheathing text was not read for this record, and this record does not decide which edition the Township applies.
Sales & use tax
6% Pennsylvania sales and use tax, with a local tax added on purchases made in Allegheny County (1%) and Philadelphia (2%). On a reroof the roofer pays the tax on the materials and does not add it to the homeowner's bill. The Department of Revenue says: "The Pennsylvania sales tax rate is 6 percent. By law, a 1 percent local tax is added to purchases made in Allegheny County, and 2 percent local tax is added to purchases made in Philadelphia." Roof work is a construction activity: the rule's list of items "presumed to become a permanent part of real estate" includes "Roofing (repairs)" (61 Pa. Code 31.11). For construction activities, "A contractor shall pay tax upon the purchase price ... of all property, including materials, equipment, components and supplies, which he furnishes and installs" (61 Pa. Code 31.12(a)(1)), and the rule's example says the contractor "does not charge sales tax on this transaction to his customer. The contractor may include the tax he must pay in his bid proposal but not as a separately stated item." Apart from limited exceptions set out in the rule, the same holds on jobs for tax-exempt owners: "a contractor erecting a building, repairing a roof, replacing a door for a governmental agency, ... school district, charitable or religious organization, and the like, shall pay tax upon the property which he consumes" (61 Pa. Code 31.13(a)). Everything above is Pennsylvania state law, the same in every municipality. South Londonderry Township is in Lebanon County. The Township's permit pages and fee schedules say nothing on sales tax.

When does a roof repair need a permit in Township of South Londonderry, PA?

No South Londonderry Township text read names reroofing as permit work or as exempt. The Township's Zoning, Building & Land Development page (read October 9, 2026) says "Permits are required to repair, construct, enlarge, alter, or demolish a building or structure," and that the Township "follows the Uniform Construction Code (UCC) as the standard for building, construction, remodeling, and repairs"; it names no roof work. The Commonwealth Code Inspection Service application lists the improvement types "New," "Addition," "Alteration," "Repair/Replacement," "Relocation" and "Other," and the Associated Building Inspections application lists "Alteration or Renovation" among its types; neither names roofing. Neither agency's 2025 residential fee schedule nor the Township's 2026 fee schedule has a roofing line. The Township's Uniform Construction Code ordinance was not read for this record: it is not among the ordinances posted on the Township's Ordinance Information page, and no online copy of the Township's code was found, so any permit or exemption section in it, and any older building ordinance it keeps in force, were not read. 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." The Township's statement names no roof work, no agency document read names reroofing as permit work or as exempt, and the Township's code could not be read, so this record does not decide whether the Township requires a permit for an ordinary reroof. Ask the Township office at 717-838-5556 before work starts. State law sets no square-footage or percentage threshold for roof work; any threshold is set locally. The Uniform Construction Code "does not apply to" "Alterations to residential buildings which do not make structural changes or changes to means of egress, except as required by ordinances in effect under sections 303(b)(1) or 503 of the act" or to "Repairs to residential buildings, except as required by ordinances in effect under sections 303(b)(1) and 503 of the act" (34 Pa. Code 403.1(b)(8) and (9)), and "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" (34 Pa. Code 403.62(c)). For houses the regulation adds: "An ordinary repair does not require a permit." Its list of work that is not an ordinary repair names cutting away a load-bearing wall, "The removal or cutting of any structural beam or load-bearing support," changes to a required means of egress, and new or relocated piping, wiring or mechanical work (34 Pa.

Can you roof over an existing roof in Township of South Londonderry, PA?

Two layers at most where the state code reaches the job. Pennsylvania adopts the 2021 International Residential Code without changing its reroofing section, R908 (34 Pa. Code 403.21(a)(7); the State's list of changes names no Chapter 9 section). Section R908.3.1.1 says "A roof recover shall not be permitted where any of the following conditions occur," and the third condition is "Where the existing roof has two or more applications of any type of roof covering." So one existing layer may be covered once, and a roof that already has two layers is torn off to the deck. The same section also bars a recover "Where the existing roof or roof covering is water soaked or has deteriorated to the point that the existing roof or roof covering is not adequate as a base for additional roofing" and "Where the existing roof covering is slate, clay, cement or asbestos-cement tile." The existing-building code the State also adopts, the 2021 International Existing Building Code (34 Pa. Code 403.21(f)), carries the same three conditions in Section 705.2.1.1. These rules bind work the Uniform Construction Code reaches. The Act does not apply to "Repairs to residential buildings" or to alterations that make no structural change, "except as might be required by ordinances" (Act 45 section 104(b)(5) and (6)), so whether R908 binds a particular house reroof turns on that exclusion and on the municipality's own ordinances. Everything above is Pennsylvania state law, the same in every municipality. Locally, South Londonderry Township administers the code through two inspection agencies under contract to it: its Zoning, Building & Land Development page says "An application for a permit is to be filed with the Township and no work shall commence until permit is issued" and that "building inspections and plan reviews are completed by a third party agency under contract to the Township.

The Commonwealth Code Inspection Service application the Township posts says "Applicable Codes: 2009 IBC/IRC, 2012 IBC Chapter 11, 2009 ICC A11 7.1," and the Township's own pages name no edition; the text above is the 2021 edition's, the 2009 edition's reroofing text was not read for this record, and this record does not decide which edition the Township applies.

Do roofing contractors need a license or registration in Township of South Londonderry, PA?

Yes.

What building code does Township of South Londonderry, PA use?

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.
