Adopted code

Antrim Township - Land Use & Building

Antrim Township, Franklin County, issues land use permits at its office at 10655 Antrim Church Road, Greencastle, and sends building permits to one of two third-party building code officials, Commonwealth Code Inspection Service and Pennsylvania Municipal Code Alliance, both in Chambersburg. 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
This record does not state whether Antrim Township requires a building permit for a house reroof; the Township Code and the Township's pages name no roof work either way. No ordinance reaching residential reroofing was found. Section 65-2 of the Township Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code of Antrim Township, and Section 65-6 A repeals all building code ordinances the Township adopted before it. Section 65-6 C requires a separate Township land use permit: "When any building or construction activity is contemplated within the Township, application shall first be made to the Township at the Township offices on a form to be provided by the Township for the issuance of a land use permit," and Section 150-84 A(1) says "No building or structure in excess of one-hundred (100) square feet, in any district, shall be placed, erected or structurally altered without a land use permit"; neither names roof work, and neither is a building permit requirement. Section 65-7 leaves fees to resolution, and a search of the whole Township Code found no provision that requires or exempts a permit for roofing. The Township's own pages name no roof work: the Land Use & Building page says "Most construction projects in Antrim Township require two permits, a Land Use Permit obtained from the Township and a Building Permit obtained from our authorized Uniform Construction Code Official," and that the Township requires land use permits "for the placement, construction or alteration of any building or structure larger than 100 square feet," adding that "Remodeling, enhancing, or repairing a structure may require a land use permit"; the Township's 2026 Fee Schedule has no roofing line. Pennsylvania Municipal Code Alliance's own website answers "I am re-roofing my residential structure – do I need a building permit?" without naming Antrim Township, and Commonwealth Code Inspection Service's pages were not read; the Township has published no statement on reroofing. 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." Ask the Township's zoning staff at 717-597-3818, or the building code official, before starting. Section 65-5 sets a fine of "not less than $250 nor more than $1,000, together with all costs" for violations of the article. Read for this answer: Chapter 65 of the Township Code, Construction Codes, Uniform, in full, which is the Township's Uniform Construction Code ordinance and its permit provisions; Chapter 150, Zoning, Sections 150-53, 150-69, 150-83 to 150-85 and the Flood Hazard District sections 150-35, 150-42 to 150-44 and 150-48; a search of the whole Township Code for "roof" and for "reroofing"; the Township's Land Use & Building, Permits and Ordinances pages; the 2026 Fee Schedule, which has no roofing line; the Guide to Land-Use Permitting; the Land Use Permit Application; and Pennsylvania Municipal Code Alliance's home, FAQ, permit applications and locations pages.
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, Antrim Township, Franklin County, does not run the building permit itself: its Land Use & Building page says the Township "chose to implement this program by outsourcing to third party Uniform Construction Code Officials" and that building permits "may be obtained from one of our two Building Code Officials," Commonwealth Code Inspection Service, Inc. (1102 Sheller Avenue, Chambersburg, 717-262-0081) and Pennsylvania Municipal Code Alliance, Inc. (1013 Wayne Avenue, Chambersburg, 717-496-4996). The Township itself issues the land use permit, at 10655 Antrim Church Road, Greencastle. No ordinance reaching residential reroofing was found. Section 65-2 of the Township Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code of Antrim Township, and Section 65-6 A repeals all building code ordinances the Township adopted before it. Section 65-6 C requires a separate Township land use permit: "When any building or construction activity is contemplated within the Township, application shall first be made to the Township at the Township offices on a form to be provided by the Township for the issuance of a land use permit," and Section 150-84 A(1) says "No building or structure in excess of one-hundred (100) square feet, in any district, shall be placed, erected or structurally altered without a land use permit"; neither names roof work, and neither is a building permit requirement. Section 65-7 leaves fees to resolution, and a search of the whole Township Code found no provision that requires or exempts a permit for roofing. The only code edition the Township Code names is in its flood hazard article, Section 150-35 B(7): "the 2006 IBC and the 2006 IRC or latest revisions thereof"; the Township's pages name none; this record has not read the 2006 edition's text and does not decide which edition the Township applies.
Repair permit threshold
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, Antrim Township, Franklin County, does not run the building permit itself: its Land Use & Building page says the Township "chose to implement this program by outsourcing to third party Uniform Construction Code Officials" and that building permits "may be obtained from one of our two Building Code Officials," Commonwealth Code Inspection Service, Inc. (1102 Sheller Avenue, Chambersburg, 717-262-0081) and Pennsylvania Municipal Code Alliance, Inc. (1013 Wayne Avenue, Chambersburg, 717-496-4996). The Township itself issues the land use permit, at 10655 Antrim Church Road, Greencastle. No ordinance reaching residential reroofing was found. Section 65-2 of the Township Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code of Antrim Township, and Section 65-6 A repeals all building code ordinances the Township adopted before it. Section 65-6 C requires a separate Township land use permit: "When any building or construction activity is contemplated within the Township, application shall first be made to the Township at the Township offices on a form to be provided by the Township for the issuance of a land use permit," and Section 150-84 A(1) says "No building or structure in excess of one-hundred (100) square feet, in any district, shall be placed, erected or structurally altered without a land use permit"; neither names roof work, and neither is a building permit requirement. Section 65-7 leaves fees to resolution, and a search of the whole Township Code found no provision that requires or exempts a permit for roofing. The Township's own pages name no roof work: the Land Use & Building page says "Most construction projects in Antrim Township require two permits, a Land Use Permit obtained from the Township and a Building Permit obtained from our authorized Uniform Construction Code Official," and that the Township requires land use permits "for the placement, construction or alteration of any building or structure larger than 100 square feet," adding that "Remodeling, enhancing, or repairing a structure may require a land use permit"; the Township's 2026 Fee Schedule has no roofing line. Pennsylvania Municipal Code Alliance's own website answers "I am re-roofing my residential structure – do I need a building permit?" without naming Antrim Township, and Commonwealth Code Inspection Service's pages were not read; the Township has published no statement on reroofing. So whether a Township ordinance brings a house reroof within the Uniform Construction Code is not stated here.
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, Antrim Township, Franklin County, does not run the building permit itself: its Land Use & Building page says the Township "chose to implement this program by outsourcing to third party Uniform Construction Code Officials" and that building permits "may be obtained from one of our two Building Code Officials," Commonwealth Code Inspection Service, Inc. (1102 Sheller Avenue, Chambersburg, 717-262-0081) and Pennsylvania Municipal Code Alliance, Inc. (1013 Wayne Avenue, Chambersburg, 717-496-4996). The Township itself issues the land use permit, at 10655 Antrim Church Road, Greencastle. No ordinance reaching residential reroofing was found. Section 65-2 of the Township Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code of Antrim Township, and Section 65-6 A repeals all building code ordinances the Township adopted before it. Section 65-6 C requires a separate Township land use permit: "When any building or construction activity is contemplated within the Township, application shall first be made to the Township at the Township offices on a form to be provided by the Township for the issuance of a land use permit," and Section 150-84 A(1) says "No building or structure in excess of one-hundred (100) square feet, in any district, shall be placed, erected or structurally altered without a land use permit"; neither names roof work, and neither is a building permit requirement. Section 65-7 leaves fees to resolution, and a search of the whole Township Code found no provision that requires or exempts a permit for roofing. The Township's pages say nothing on roof layers. The only code edition the Township Code names is in its flood hazard article, Section 150-35 B(7): "the 2006 IBC and the 2006 IRC or latest revisions thereof"; the Township's pages name none; the text above is the 2021 edition's, and the 2006 edition's reroofing text was not read for this record.
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, Antrim Township, Franklin County, does not run the building permit itself: its Land Use & Building page says the Township "chose to implement this program by outsourcing to third party Uniform Construction Code Officials" and that building permits "may be obtained from one of our two Building Code Officials," Commonwealth Code Inspection Service, Inc. (1102 Sheller Avenue, Chambersburg, 717-262-0081) and Pennsylvania Municipal Code Alliance, Inc. (1013 Wayne Avenue, Chambersburg, 717-496-4996). The Township itself issues the land use permit, at 10655 Antrim Church Road, Greencastle. No ordinance reaching residential reroofing was found. Section 65-2 of the Township Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code of Antrim Township, and Section 65-6 A repeals all building code ordinances the Township adopted before it. Section 65-6 C requires a separate Township land use permit: "When any building or construction activity is contemplated within the Township, application shall first be made to the Township at the Township offices on a form to be provided by the Township for the issuance of a land use permit," and Section 150-84 A(1) says "No building or structure in excess of one-hundred (100) square feet, in any district, shall be placed, erected or structurally altered without a land use permit"; neither names roof work, and neither is a building permit requirement. Section 65-7 leaves fees to resolution, and a search of the whole Township Code found no provision that requires or exempts a permit for roofing. The Township's pages draw no line for roof sheathing. The only code edition the Township Code names is in its flood hazard article, Section 150-35 B(7): "the 2006 IBC and the 2006 IRC or latest revisions thereof"; the Township's pages name none; the text above is the 2021 edition's, and the 2006 edition's sheathing text was not read for this record.
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. Antrim Township is in Franklin County. The Township's permit pages and fee schedule say nothing on sales tax.

Roofing questions: Township of Antrim, PA

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

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, Antrim Township, Franklin County, does not run the building permit itself: its Land Use & Building page says the Township "chose to implement this program by outsourcing to third party Uniform Construction Code Officials" and that building permits "may be obtained from one of our two Building Code Officials," Commonwealth Code Inspection Service, Inc. (1102 Sheller Avenue, Chambersburg, 717-262-0081) and Pennsylvania Municipal Code Alliance, Inc. (1013 Wayne Avenue, Chambersburg, 717-496-4996). The Township itself issues the land use permit, at 10655 Antrim Church Road, Greencastle. No ordinance reaching residential reroofing was found. Section 65-2 of the Township Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code of Antrim Township, and Section 65-6 A repeals all building code ordinances the Township adopted before it. Section 65-6 C requires a separate Township land use permit: "When any building or construction activity is contemplated within the Township, application shall first be made to the Township at the Township offices on a form to be provided by the Township for the issuance of a land use permit," and Section 150-84 A(1) says "No building or structure in excess of one-hundred (100) square feet, in any district, shall be placed, erected or structurally altered without a land use permit"; neither names roof work, and neither is a building permit requirement. Section 65-7 leaves fees to resolution, and a search of the whole Township Code found no provision that requires or exempts a permit for roofing. The Township's own pages name no roof work: the Land Use & Building page says "Most construction projects in Antrim Township require two permits, a Land Use Permit obtained from the Township and a Building Permit obtained from our authorized Uniform Construction Code Official," and that the Township requires land use permits "for the placement, construction or alteration of any building or structure larger than 100 square feet," adding that "Remodeling, enhancing, or repairing a structure may require a land use permit"; the Township's 2026 Fee Schedule has no roofing line. Pennsylvania Municipal Code Alliance's own website answers "I am re-roofing my residential structure – do I need a building permit?" without naming Antrim Township, and Commonwealth Code Inspection Service's pages were not read; the Township has published no statement on reroofing. So whether a Township ordinance brings a house reroof within the Uniform Construction Code is not stated here.

Can you roof over an existing roof in Township of Antrim, 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, Antrim Township, Franklin County, does not run the building permit itself: its Land Use & Building page says the Township "chose to implement this program by outsourcing to third party Uniform Construction Code Officials" and that building permits "may be obtained from one of our two Building Code Officials," Commonwealth Code Inspection Service, Inc. (1102 Sheller Avenue, Chambersburg, 717-262-0081) and Pennsylvania Municipal Code Alliance, Inc. (1013 Wayne Avenue, Chambersburg, 717-496-4996). The Township itself issues the land use permit, at 10655 Antrim Church Road, Greencastle. No ordinance reaching residential reroofing was found. Section 65-2 of the Township Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code of Antrim Township, and Section 65-6 A repeals all building code ordinances the Township adopted before it. Section 65-6 C requires a separate Township land use permit: "When any building or construction activity is contemplated within the Township, application shall first be made to the Township at the Township offices on a form to be provided by the Township for the issuance of a land use permit," and Section 150-84 A(1) says "No building or structure in excess of one-hundred (100) square feet, in any district, shall be placed, erected or structurally altered without a land use permit"; neither names roof work, and neither is a building permit requirement. Section 65-7 leaves fees to resolution, and a search of the whole Township Code found no provision that requires or exempts a permit for roofing. The Township's pages say nothing on roof layers. The only code edition the Township Code names is in its flood hazard article, Section 150-35 B(7): "the 2006 IBC and the 2006 IRC or latest revisions thereof"; the Township's pages name none; the text above is the 2021 edition's, and the 2006 edition's reroofing text was not read for this record.

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

Yes.

What building code does Township of Antrim, 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. Locally, Antrim Township, Franklin County, does not run the building permit itself: its Land Use & Building page says the Township "chose to implement this program by outsourcing to third party Uniform Construction Code Officials" and that building permits "may be obtained from one of our two Building Code Officials," Commonwealth Code Inspection Service, Inc. (1102 Sheller Avenue, Chambersburg, 717-262-0081) and Pennsylvania Municipal Code Alliance, Inc. (1013 Wayne Avenue, Chambersburg, 717-496-4996). The Township itself issues the land use permit, at 10655 Antrim Church Road, Greencastle. No ordinance reaching residential reroofing was found. Section 65-2 of the Township Code adopts the Uniform Construction Code "as amended from time to time" as the Municipal Building Code of Antrim Township, and Section 65-6 A repeals all building code ordinances the Township adopted before it. Section 65-6 C requires a separate Township land use permit: "When any building or construction activity is contemplated within the Township, application shall first be made to the Township at the Township offices on a form to be provided by the Township for the issuance of a land use permit," and Section 150-84 A(1) says "No building or structure in excess of one-hundred (100) square feet, in any district, shall be placed, erected or structurally altered without a land use permit"; neither names roof work, and neither is a building permit requirement. Section 65-7 leaves fees to resolution, and a search of the whole Township Code found no provision that requires or exempts a permit for roofing. The only code edition the Township Code names is in its flood hazard article, Section 150-35 B(7): "the 2006 IBC and the 2006 IRC or latest revisions thereof"; the Township's pages name none; this record has not read the 2006 edition's text and does not decide which edition the Township applies.
