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

Adopted code

City of Lebanon - Building and Zoning Division

Yes, a permit is required to replace a roof in Lebanon, PA, issued by City of Lebanon - Building and Zoning Division. The City of Lebanon's enacted fee schedule names roofing as permit work, but its permit guide and application list residential shingle replacement as exempt. Section 1701.06 of the City's Codified Ordinances, as amended by Ordinance 9-2024 (passed October 27, 2025), sets the building permit fees and lists, for residential one- and two-family dwellings, "Renovations/alterations (based on fair market value of project cost), Including roofing, electrical/heating/plumbing/solar and single trade miscellaneous," at $60 for a project of $1 to $10,000, $75 to $50,000, $100 to $100,000 and $125 above that; the fee line is not limited to any kind of roof work. The City's own guidance says otherwise for shingles: its Residential Permit Reference Guide (read October 6, 2026) lists under "No Permit Required" the item "Re-Roof (residential shingle replacement only)," and the exempt projects printed on its current Building Permit Application include "Residential shingle replacement." Article 1703 adopts the 2018 International Residential Code (Ordinance 11-2024, passed October 27, 2025) as the Residential Code of the City for the construction, alteration, replacement and repair of one- and two-family dwellings and townhouses, "providing for the issuance of permits and collection of fees therefore"; the permit sections of the 2018 edition were not read for this record, and the only change Section 1703.02 makes that touches permits is to delete Appendix L, Permit Fees. 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, the City's enacted fee schedule prices roofing as permit work while its guide and application tell homeowners that residential shingle replacement needs no permit; the guide says "If in doubt call the City of Lebanon Zoning Officer" at 717-639-2800, option 4, and Section 1701.06 says "Work started (or signs installed) without a permit are subject to twice the regular permit fee." Permit applications are filed with the Zoning Office; before a permit issues, "the contractor must submit a copy of a Certificate of Liability Insurance and proof of Workers Compensation Insurance Coverage or a valid notarized exemption," and the City asks home improvement contractors for their Attorney General registration number. Plans and permits come back from the inspection company "for pickup and payment in the Department of Public Works, 2nd Floor at 735 Cumberland Street," and inspections are booked with the chosen company at least 24 hours ahead.

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 Lebanon administers the code through its Building and Zoning Division and two contracted inspection companies: Section 1701.01 of the City's Codified Ordinances says "This municipality hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Division's page says "Building Code inspection companies are Commonwealth Code Inspection Services (1-800-732-0043), Inc or ABI Inspection Services (717-733-1654). They are under contract to provide residential and non-residential construction code inspections," and that "Building permits are received by the Zoning Office of the City of Lebanon and forwarded to the inspection company you have chosen." Section 1701.02 adopts the Uniform Construction Code, "as amended from time to time," as the City's building code, while Article 1703 adopts the 2018 International Residential Code and Article 1702 the 2018 International Building Code (Ordinances 11-2024 and 10-2024, both passed October 27, 2025), and the Division's page lists the "International Residential Code, 2018 Edition, as amended by the City of Lebanon" among the codes projects must comply with; the application says "Plans will be reviewed and inspected according to 2018 UCC Code." So the City's own code and pages name the 2018 edition while the State's rule names the 2021 edition; this record has not read the 2018 edition's roofing text. Section 1703.02 changes nothing in the code's roof provisions; it fills in Table R301.2(1), including "Ice Barrier Underlayment Required = yes."
Repair permit threshold
The City of Lebanon's enacted fee schedule names roofing as permit work, and its guidance exempts residential shingle replacement. Section 1701.06 of the City's Codified Ordinances, as amended by Ordinance 9-2024 (passed October 27, 2025), sets the building permit fees and lists, for residential one- and two-family dwellings, "Renovations/alterations (based on fair market value of project cost), Including roofing, electrical/heating/plumbing/solar and single trade miscellaneous," at $60 for a project of $1 to $10,000, $75 to $50,000, $100 to $100,000 and $125 above that; the fee line is not limited to any kind of roof work. The City's own guidance says otherwise for shingles: its Residential Permit Reference Guide (read October 6, 2026) lists under "No Permit Required" the item "Re-Roof (residential shingle replacement only)," and the exempt projects printed on its current Building Permit Application include "Residential shingle replacement." Article 1703 adopts the 2018 International Residential Code (Ordinance 11-2024, passed October 27, 2025) as the Residential Code of the City for the construction, alteration, replacement and repair of one- and two-family dwellings and townhouses, "providing for the issuance of permits and collection of fees therefore"; the permit sections of the 2018 edition were not read for this record, and the only change Section 1703.02 makes that touches permits is to delete Appendix L, Permit Fees. 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, the City's enacted fee schedule prices roofing as permit work while its guide and application tell homeowners that residential shingle replacement needs no permit; the guide says "If in doubt call the City of Lebanon Zoning Officer" at 717-639-2800, option 4, and Section 1701.06 says "Work started (or signs installed) without a permit are subject to twice the regular 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 Lebanon administers the code through its Building and Zoning Division and two contracted inspection companies: Section 1701.01 of the City's Codified Ordinances says "This municipality hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Division's page says "Building Code inspection companies are Commonwealth Code Inspection Services (1-800-732-0043), Inc or ABI Inspection Services (717-733-1654). They are under contract to provide residential and non-residential construction code inspections," and that "Building permits are received by the Zoning Office of the City of Lebanon and forwarded to the inspection company you have chosen." The only line the City draws for roof work is the guidance's exemption for "residential shingle replacement only," quoted at the start; Part 17 of the Codified Ordinances sets no area 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, The City of Lebanon administers the code through its Building and Zoning Division and two contracted inspection companies: Section 1701.01 of the City's Codified Ordinances says "This municipality hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Division's page says "Building Code inspection companies are Commonwealth Code Inspection Services (1-800-732-0043), Inc or ABI Inspection Services (717-733-1654). They are under contract to provide residential and non-residential construction code inspections," and that "Building permits are received by the Zoning Office of the City of Lebanon and forwarded to the inspection company you have chosen." Article 1703 changes nothing in the code's reroofing provisions, and the Division's pages say nothing on roof layers. Article 1703 of the City's Codified Ordinances adopts the 2018 International Residential Code, and the Division's page says construction projects must comply with the "International Residential Code, 2018 Edition, as amended by the City of Lebanon"; the text above is the 2021 edition's, and the 2018 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, The City of Lebanon administers the code through its Building and Zoning Division and two contracted inspection companies: Section 1701.01 of the City's Codified Ordinances says "This municipality hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Division's page says "Building Code inspection companies are Commonwealth Code Inspection Services (1-800-732-0043), Inc or ABI Inspection Services (717-733-1654). They are under contract to provide residential and non-residential construction code inspections," and that "Building permits are received by the Zoning Office of the City of Lebanon and forwarded to the inspection company you have chosen." Article 1703 changes nothing in the code's roof sheathing provisions, and the Division's pages draw no line for roof sheathing. Article 1703 of the City's Codified Ordinances adopts the 2018 International Residential Code, and the Division's page says construction projects must comply with the "International Residential Code, 2018 Edition, as amended by the City of Lebanon"; the text above is the 2021 edition's, and the 2018 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. The City of Lebanon is in Lebanon County. The Division's pages and Section 1701.06 say nothing on sales tax.

Roofing questions: Lebanon, PA

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

Yes, a permit is required to replace a roof in Lebanon, PA. The City of Lebanon's enacted fee schedule names roofing as permit work, and its guidance exempts residential shingle replacement. Section 1701.06 of the City's Codified Ordinances, as amended by Ordinance 9-2024 (passed October 27, 2025), sets the building permit fees and lists, for residential one- and two-family dwellings, "Renovations/alterations (based on fair market value of project cost), Including roofing, electrical/heating/plumbing/solar and single trade miscellaneous," at $60 for a project of $1 to $10,000, $75 to $50,000, $100 to $100,000 and $125 above that; the fee line is not limited to any kind of roof work. The City's own guidance says otherwise for shingles: its Residential Permit Reference Guide (read October 6, 2026) lists under "No Permit Required" the item "Re-Roof (residential shingle replacement only)," and the exempt projects printed on its current Building Permit Application include "Residential shingle replacement." Article 1703 adopts the 2018 International Residential Code (Ordinance 11-2024, passed October 27, 2025) as the Residential Code of the City for the construction, alteration, replacement and repair of one- and two-family dwellings and townhouses, "providing for the issuance of permits and collection of fees therefore"; the permit sections of the 2018 edition were not read for this record, and the only change Section 1703.02 makes that touches permits is to delete Appendix L, Permit Fees. 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, the City's enacted fee schedule prices roofing as permit work while its guide and application tell homeowners that residential shingle replacement needs no permit; the guide says "If in doubt call the City of Lebanon Zoning Officer" at 717-639-2800, option 4, and Section 1701.06 says "Work started (or signs installed) without a permit are subject to twice the regular 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 Lebanon administers the code through its Building and Zoning Division and two contracted inspection companies: Section 1701.01 of the City's Codified Ordinances says "This municipality hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Division's page says "Building Code inspection companies are Commonwealth Code Inspection Services (1-800-732-0043), Inc or ABI Inspection Services (717-733-1654). They are under contract to provide residential and non-residential construction code inspections," and that "Building permits are received by the Zoning Office of the City of Lebanon and forwarded to the inspection company you have chosen." The only line the City draws for roof work is the guidance's exemption for "residential shingle replacement only," quoted at the start; Part 17 of the Codified Ordinances sets no area or cost threshold.

Can you roof over an existing roof in Lebanon, 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 Lebanon administers the code through its Building and Zoning Division and two contracted inspection companies: Section 1701.01 of the City's Codified Ordinances says "This municipality hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Division's page says "Building Code inspection companies are Commonwealth Code Inspection Services (1-800-732-0043), Inc or ABI Inspection Services (717-733-1654). They are under contract to provide residential and non-residential construction code inspections," and that "Building permits are received by the Zoning Office of the City of Lebanon and forwarded to the inspection company you have chosen." Article 1703 changes nothing in the code's reroofing provisions, and the Division's pages say nothing on roof layers. Article 1703 of the City's Codified Ordinances adopts the 2018 International Residential Code, and the Division's page says construction projects must comply with the "International Residential Code, 2018 Edition, as amended by the City of Lebanon"; the text above is the 2021 edition's, and the 2018 edition's reroofing text was not read for this record.

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

Yes.

What building code does Lebanon, 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 Lebanon administers the code through its Building and Zoning Division and two contracted inspection companies: Section 1701.01 of the City's Codified Ordinances says "This municipality hereby elects to administer and enforce the provisions of the Pennsylvania Construction Code Act," and the Division's page says "Building Code inspection companies are Commonwealth Code Inspection Services (1-800-732-0043), Inc or ABI Inspection Services (717-733-1654). They are under contract to provide residential and non-residential construction code inspections," and that "Building permits are received by the Zoning Office of the City of Lebanon and forwarded to the inspection company you have chosen." Section 1701.02 adopts the Uniform Construction Code, "as amended from time to time," as the City's building code, while Article 1703 adopts the 2018 International Residential Code and Article 1702 the 2018 International Building Code (Ordinances 11-2024 and 10-2024, both passed October 27, 2025), and the Division's page lists the "International Residential Code, 2018 Edition, as amended by the City of Lebanon" among the codes projects must comply with; the application says "Plans will be reviewed and inspected according to 2018 UCC Code." So the City's own code and pages name the 2018 edition while the State's rule names the 2021 edition; this record has not read the 2018 edition's roofing text. Section 1703.02 changes nothing in the code's roof provisions; it fills in Table R301.2(1), including "Ice Barrier Underlayment Required = yes."
