Do you need a permit to replace a roof in Coatesville, PA?

Adopted code

City of Coatesville - Codes Department

Yes, a permit is required to replace a roof in Coatesville, PA, issued by City of Coatesville - Codes Department. The City of Coatesville's code requires permits for repairs to any building, and the City has published no exemption for a reroof. Section 82-9 B of the City Code (adopted November 22, 1993 by Ordinance No. 944-93; Section 82-9 last amended August 13, 2001) says "Permits shall be required for the construction, alteration, conversion, removal, demolition, repair and/or maintenance of any building or the addition to existing buildings." It names no roof work, and Section 82-9 A adds only that "No fee shall be required for permits for repairs which involve the reconstruction or renewal of any part of an existing structure for the purpose of maintenance with a total cost valued at less than $250." Section 212-5 A keeps building code ordinances adopted on or before July 1, 1999 "and which equal or exceed the requirements of the Code" in force, and Chapter 212 adopts the Uniform Construction Code, which says "An ordinary repair does not require a permit" (34 Pa. Code 403.62) without defining an ordinary repair. This record does not decide how Section 212-5 bears on Section 82-9. The Codes Department has published nothing on reroofing. Its page (read October 7, 2026) says "IF YOU ARE PLANNING TO COMPLETE ANY HOME IMPROVEMENTS, BE SURE TO CONTACT OUR CODES DEPARTMENT FIRST TO ENSURE WHETHER YOU NEED A PERMIT FOR THE WORK GETTING DONE!" The Construction Permit Application offers "Repair" and "Alteration" as types of work and has no roofing line, and the 2026 Master Fee Schedule (Resolution No. 2025-15) prices residential "Alterations, Repairs, Modifications" at "$0.40/SF minimum $300.00" with no roofing line in its residential building permit section. 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 of a municipal ordinance that adds to the code, section 503(c) says "An ordinance under this subsection shall not be effective nor enforceable unless subsections (d), (e), (f), (g), (h) and (i) have been satisfied." This record does not decide whether the municipality's requirement is one adopted under section 503 or kept in effect by section 303(b)(1). In practice, Section 82-9 B names repairs without exception and the City has published no exemption for a reroof, so expect to need a building permit. Under Section 82-10 C, a person who does work requiring a permit "without first obtaining the required permits" and is convicted "shall be sentenced to pay a fine of up to $500 and/or to imprisonment for not more than 30 days and further shall pay two times the appropriate permit fee." The application asks for the contractor's PA Contractor Registration number and a copy of the workers' compensation certificate, and the City's contractor insurance registration under Chapter 84 applies to construction contractors. Inspections are scheduled through the Codes Department Tuesday through Thursday; the department is open Monday to Friday, 8:30 a.m. to 4 p.m., at 610-384-0300. Read for this answer: Chapter 212 of the City Code, Uniform Construction Code (Sections 212-1 to 212-6), in full; Chapter 82, Building Construction, Article II, Building Code (Sections 82-9 to 82-12) and Article III, Residential Dwelling Code (Sections 82-13 to 82-16), in full; Chapter 84, Contractor Licensing and Insurance Registration Certificate; Chapter 108, Fees, which leaves building permit fees to the City's fee schedule; every page of a search of the whole City Code for "roof" and for "reroofing," which found no permit provision naming roof work; the Codes and Permits and Licensing pages; the Building Permit Application; and the 2026 Master Fee Schedule, a scanned file, of which the commercial and residential building permit sections were read from the page images.

Registration details
  • state_level: Home Improvement Consumer Protection Act, Act 132 of 2008, 73 P.S. 517.1 et seq.: registration with the Attorney General's Bureau of Consumer Protection before performing any home improvement over $500 (section 2, section 3(a)); persons whose home improvements totalled less than $5,000 in the previous taxable year are not "contractors" (section 2). Section 12 precludes local registration or licensing of home improvement contractors, with carve-outs for building permits, pre-existing tested trade licences, and local insurance standards adopted before January 1, 2006.
  • city_level: Section 84-7 of the City Code (added January 24, 2011) says no entity shall "engage in business within the City of Coatesville as a construction contractor without first obtaining an insurance registration certificate from the City's Code Office," with minimum general liability, automobile and workers' compensation coverage, and Section 84-1 requires a City contractor license; the 2026 Master Fee Schedule lists a Contractor registration fee of $125.00. This record does not decide how section 12 of the state Act bears on Chapter 84.

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, The City of Coatesville issues building permits through its Codes Department at 1 City Hall Place. Section 212-1 of the City Code says "The City of Coatesville hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Codes Department's page lists a Codes Supervisor and names LTL Consultants as the City's "Licensing and Codes Engineers"; the City's Building Permit Application says "LTL makes every effort to process and issue residential permits within 10 working days." Section 212-2 adopts the Uniform Construction Code, "as amended from time to time," as the City's municipal building code; Chapter 212 changes nothing in the code's roofing provisions, and Chapter 82 amends only administrative and penalty sections. Chapter 82 of the City Code adopts the "International Building Code," 2000 Edition (Section 82-9) and the "International Residential Code for One- and Two-Family Dwellings," 2000 Edition (Section 82-13), and the Codes Department's page says the City "refers to" the Pennsylvania Uniform Construction Code and the "2018 ICC Codes (with the exception of Chapter 11 of the IBC, 2018)" and names no later edition; this record has not read the 2000 or 2018 editions' text and does not decide which edition the City applies.
Repair permit threshold
The City of Coatesville's code requires permits for repairs to any building, and the City has published no exemption for a reroof. Section 82-9 B of the City Code (adopted November 22, 1993 by Ordinance No. 944-93; Section 82-9 last amended August 13, 2001) says "Permits shall be required for the construction, alteration, conversion, removal, demolition, repair and/or maintenance of any building or the addition to existing buildings." It names no roof work, and Section 82-9 A adds only that "No fee shall be required for permits for repairs which involve the reconstruction or renewal of any part of an existing structure for the purpose of maintenance with a total cost valued at less than $250." Section 212-5 A keeps building code ordinances adopted on or before July 1, 1999 "and which equal or exceed the requirements of the Code" in force, and Chapter 212 adopts the Uniform Construction Code, which says "An ordinary repair does not require a permit" (34 Pa. Code 403.62) without defining an ordinary repair. This record does not decide how Section 212-5 bears on Section 82-9. The Codes Department has published nothing on reroofing. Its page (read October 7, 2026) says "IF YOU ARE PLANNING TO COMPLETE ANY HOME IMPROVEMENTS, BE SURE TO CONTACT OUR CODES DEPARTMENT FIRST TO ENSURE WHETHER YOU NEED A PERMIT FOR THE WORK GETTING DONE!" The Construction Permit Application offers "Repair" and "Alteration" as types of work and has no roofing line, and the 2026 Master Fee Schedule (Resolution No. 2025-15) prices residential "Alterations, Repairs, Modifications" at "$0.40/SF minimum $300.00" with no roofing line in its residential building permit section. 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 of a municipal ordinance that adds to the code, section 503(c) says "An ordinance under this subsection shall not be effective nor enforceable unless subsections (d), (e), (f), (g), (h) and (i) have been satisfied." This record does not decide whether the municipality's requirement is one adopted under section 503 or kept in effect by section 303(b)(1). In practice, Section 82-9 B names repairs without exception and the City has published no exemption for a reroof, so expect to need a building permit. Under Section 82-10 C, a person who does work requiring a permit "without first obtaining the required permits" and is convicted "shall be sentenced to pay a fine of up to $500 and/or to imprisonment for not more than 30 days and further shall pay two times the appropriate permit fee." 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, The City of Coatesville issues building permits through its Codes Department at 1 City Hall Place. Section 212-1 of the City Code says "The City of Coatesville hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Codes Department's page lists a Codes Supervisor and names LTL Consultants as the City's "Licensing and Codes Engineers"; the City's Building Permit Application says "LTL makes every effort to process and issue residential permits within 10 working days." Section 82-9 B, quoted at the start, sets no square-footage or percentage threshold for roof work, and the City's pages set none.
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, The City of Coatesville issues building permits through its Codes Department at 1 City Hall Place. Section 212-1 of the City Code says "The City of Coatesville hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Codes Department's page lists a Codes Supervisor and names LTL Consultants as the City's "Licensing and Codes Engineers"; the City's Building Permit Application says "LTL makes every effort to process and issue residential permits within 10 working days." Chapters 212 and 82 of the City Code change nothing in the code's reroofing provisions, and the City's pages say nothing on roof layers. Chapter 82 of the City Code adopts the "International Building Code," 2000 Edition (Section 82-9) and the "International Residential Code for One- and Two-Family Dwellings," 2000 Edition (Section 82-13), and the Codes Department's page says the City "refers to" the Pennsylvania Uniform Construction Code and the "2018 ICC Codes (with the exception of Chapter 11 of the IBC, 2018)" and names no later edition; the text above is the 2021 edition's, the 2000 and 2018 editions' reroofing text was not read for this record, and this record does not decide which edition the City 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, The City of Coatesville issues building permits through its Codes Department at 1 City Hall Place. Section 212-1 of the City Code says "The City of Coatesville hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Codes Department's page lists a Codes Supervisor and names LTL Consultants as the City's "Licensing and Codes Engineers"; the City's Building Permit Application says "LTL makes every effort to process and issue residential permits within 10 working days." Chapters 212 and 82 of the City Code change nothing in the code's roof sheathing provisions, and the City's pages draw no separate line for roof sheathing. Chapter 82 of the City Code adopts the "International Building Code," 2000 Edition (Section 82-9) and the "International Residential Code for One- and Two-Family Dwellings," 2000 Edition (Section 82-13), and the Codes Department's page says the City "refers to" the Pennsylvania Uniform Construction Code and the "2018 ICC Codes (with the exception of Chapter 11 of the IBC, 2018)" and names no later edition; the text above is the 2021 edition's, the 2000 and 2018 editions' sheathing text was not read for this record, and this record does not decide which edition the City 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. The City of Coatesville is in Chester County. The City's permit pages and 2026 fee schedule say nothing on sales tax.

Roofing questions: Coatesville, PA

Do you need a permit to replace a roof in Coatesville, PA?

Yes, a permit is required to replace a roof in Coatesville, PA. The City of Coatesville's code requires permits for repairs to any building, and the City has published no exemption for a reroof. Section 82-9 B of the City Code (adopted November 22, 1993 by Ordinance No. 944-93; Section 82-9 last amended August 13, 2001) says "Permits shall be required for the construction, alteration, conversion, removal, demolition, repair and/or maintenance of any building or the addition to existing buildings." It names no roof work, and Section 82-9 A adds only that "No fee shall be required for permits for repairs which involve the reconstruction or renewal of any part of an existing structure for the purpose of maintenance with a total cost valued at less than $250." Section 212-5 A keeps building code ordinances adopted on or before July 1, 1999 "and which equal or exceed the requirements of the Code" in force, and Chapter 212 adopts the Uniform Construction Code, which says "An ordinary repair does not require a permit" (34 Pa. Code 403.62) without defining an ordinary repair. This record does not decide how Section 212-5 bears on Section 82-9. The Codes Department has published nothing on reroofing. Its page (read October 7, 2026) says "IF YOU ARE PLANNING TO COMPLETE ANY HOME IMPROVEMENTS, BE SURE TO CONTACT OUR CODES DEPARTMENT FIRST TO ENSURE WHETHER YOU NEED A PERMIT FOR THE WORK GETTING DONE!" The Construction Permit Application offers "Repair" and "Alteration" as types of work and has no roofing line, and the 2026 Master Fee Schedule (Resolution No. 2025-15) prices residential "Alterations, Repairs, Modifications" at "$0.40/SF minimum $300.00" with no roofing line in its residential building permit section. 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 of a municipal ordinance that adds to the code, section 503(c) says "An ordinance under this subsection shall not be effective nor enforceable unless subsections (d), (e), (f), (g), (h) and (i) have been satisfied." This record does not decide whether the municipality's requirement is one adopted under section 503 or kept in effect by section 303(b)(1). In practice, Section 82-9 B names repairs without exception and the City has published no exemption for a reroof, so expect to need a building permit. Under Section 82-10 C, a person who does work requiring a permit "without first obtaining the required permits" and is convicted "shall be sentenced to pay a fine of up to $500 and/or to imprisonment for not more than 30 days and further shall pay two times the appropriate permit fee." 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, The City of Coatesville issues building permits through its Codes Department at 1 City Hall Place. Section 212-1 of the City Code says "The City of Coatesville hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Codes Department's page lists a Codes Supervisor and names LTL Consultants as the City's "Licensing and Codes Engineers"; the City's Building Permit Application says "LTL makes every effort to process and issue residential permits within 10 working days." Section 82-9 B, quoted at the start, sets no square-footage or percentage threshold for roof work, and the City's pages set none.

Can you roof over an existing roof in Coatesville, 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, The City of Coatesville issues building permits through its Codes Department at 1 City Hall Place. Section 212-1 of the City Code says "The City of Coatesville hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Codes Department's page lists a Codes Supervisor and names LTL Consultants as the City's "Licensing and Codes Engineers"; the City's Building Permit Application says "LTL makes every effort to process and issue residential permits within 10 working days." Chapters 212 and 82 of the City Code change nothing in the code's reroofing provisions, and the City's pages say nothing on roof layers. Chapter 82 of the City Code adopts the "International Building Code," 2000 Edition (Section 82-9) and the "International Residential Code for One- and Two-Family Dwellings," 2000 Edition (Section 82-13), and the Codes Department's page says the City "refers to" the Pennsylvania Uniform Construction Code and the "2018 ICC Codes (with the exception of Chapter 11 of the IBC, 2018)" and names no later edition; the text above is the 2021 edition's, the 2000 and 2018 editions' reroofing text was not read for this record, and this record does not decide which edition the City applies.

Do roofing contractors need a license or registration in Coatesville, PA?

Yes.

What building code does Coatesville, 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, The City of Coatesville issues building permits through its Codes Department at 1 City Hall Place. Section 212-1 of the City Code says "The City of Coatesville hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Codes Department's page lists a Codes Supervisor and names LTL Consultants as the City's "Licensing and Codes Engineers"; the City's Building Permit Application says "LTL makes every effort to process and issue residential permits within 10 working days." Section 212-2 adopts the Uniform Construction Code, "as amended from time to time," as the City's municipal building code; Chapter 212 changes nothing in the code's roofing provisions, and Chapter 82 amends only administrative and penalty sections. Chapter 82 of the City Code adopts the "International Building Code," 2000 Edition (Section 82-9) and the "International Residential Code for One- and Two-Family Dwellings," 2000 Edition (Section 82-13), and the Codes Department's page says the City "refers to" the Pennsylvania Uniform Construction Code and the "2018 ICC Codes (with the exception of Chapter 11 of the IBC, 2018)" and names no later edition; this record has not read the 2000 or 2018 editions' text and does not decide which edition the City applies.
