THE 2021 INTERNATIONAL RESIDENTIAL CODE FOR ONE- AND TWO-FAMILY DWELLINGS, ADOPTED BY ITS OWN ARTICLE WITH A LONG LOCAL AMENDMENT LIST, AND A SEPARATE 2021 IBC FOR OTHER BUILDINGS. Code of Ordinances Sec. 6-401 (Article XIV, One- and Two-Family Dwelling Code; Ord. No. 22-O-44, Section 7, adopted April 18, 2022): "A certain document ... marked and designated as 'The International Residential Code, 2021 Edition' ... be and is hereby adopted as the One- and Two-Family Dwelling Code[.]" Sec. 6-402 amends roughly sixty individual IRC sections and tables, none of them R907 or R908 (the roof re-cover sections) and exactly one of them in Chapter 9: it adds "R901.2 Concealed areas. Roofing materials shall be removed down to roof deck in concealed areas." Separately, Code of Ordinances Sec. 6-26 (Article II, Building Code; Ord. No. 22-O-17, Section 2, 3-7-2022) adopts "The International Building Code, 2021 Edition" for buildings generally, with its own amendment list at Sec. 6-27 (also silent on Chapter 9). The City's own Contractor Information page lists both, plus the 2020 NEC, the current Illinois Plumbing Code, 2021 IPMC, the Illinois Energy Efficient Building Act, 2021 IFGC, 2021 IMC and 2021 IFC, as "Approved Codes - Effective 4/1/2022." Illinois itself has adopted no residential building code reaching an existing dwelling (Illinois Capital Development Board FAQ: "The State has not adopted a building code for repairs to existing single family residences"), so the 2021 IRC and its local amendments are the whole of the applicable code here, not a floor under a state default.

Required — NOT ITSELF AMENDED BY THE CITY, SO THE BASE 2021 IRC RULE APPLIES. Article XIV's amendment list (Sec. 6-402, read in full) does not touch R905.2.8.5, the drip edge section, or any other part of R905. The unmodified 2021 IRC requires drip edge at eaves and rakes of steep-slope roof coverings. About drip edge

Required — REQUIRED, AND THE CITY GIVES TWO CONSISTENT ANSWERS. The Roofing permit page's own "ADDITIONAL ROOFING REQUIREMENTS" state plainly: "MINIMUM OF 24" OF ICE AND WATER SHIELD IS REQUIRED." Separately, the City's local Table R301.2(1) (Sec. 6-402, Ord. No. 22-O-44) inserts "Ice Barrier Underlayment Required ... Yes" alongside a Ground Snow Load of 30 and a Winter Design Temperature range of 68 degrees F to -10 degrees F. Neither document ties the requirement to eave overhang or roof pitch; the 24-inch figure is the City's own stated minimum width. About ice & water barrier

Not required — THE CITY'S OWN ROOFING PERMIT PAGE STATES IT OUTRIGHT. Under "INSPECTION REQUIREMENTS" the Roofing page reads, in full: "NO INSPECTIONS REQUIRED." No tear-off, dry-in or final inspection is called for on a roofing permit; the City instead requires the permit placard to stay posted and visible from the street during construction.

Not required — NO IMPACT-RATING REQUIREMENT APPEARS IN THE CITY'S OWN AMENDMENT LIST. Article XIV's roughly sixty amendments to the 2021 IRC (Sec. 6-402, read in full) contain no occurrence of UL 2218, Class 4, Class IV or hail; the local Table R301.2(1) inserts a design wind speed and seismic category but no impact-resistance column. Illinois itself imposes no such requirement statewide.

NO FIXED DOLLAR OR SIZE FLOOR; THE BUILDING OFFICIAL DECIDES CASE BY CASE, AND A SEPARATE 50-PERCENT VALUE RULE CAN PULL A REPAIR UP TO NEW-CONSTRUCTION STANDARDS. The City's own Roofing permit page states: "Permits are required for all roofing work within the City of Waukegan (minor repairs may be exempt by order of the Building Official)." No square-foot or dollar figure is published for what counts as a minor repair; the exemption is discretionary with the Building Official on a case-by-case basis. Separately, the City's local amendment to the 2021 International Residential Code, R102.7.1 (Sec. 6-402, Ord. No. 22-O-44, Section 7, 4-18-2022), adds: "Additions, Alterations or Repairs exceeding 50 percent. If alterations or repairs are made within any period of 12 months, costing in excess of 50 percent of the physical value of the structure, this code's requirements for new structures shall apply." A reroof that combines with other work within twelve months to clear that 50 percent threshold is treated as new construction rather than a repair.

115 MPH, LOCALLY INSERTED INTO TABLE R301.2(1). Sec. 6-402 (Ord. No. 22-O-44, Section 7, 4-18-2022) amends Table R301.2(1) Climatic and Geographic Design Criteria by inserting, under each category: "Ground snow load ... 30", "Wind Speed ... 115", "Seismic Design Category ... A", "Weathering ... Severe", "Frost Line Depth ... 42 inches", "Termite ... Moderate to Heavy", "Winter Design Temperature for Heating Facility ... 68 F to -10 F w/50% humidity", "Ice Barrier Underlayment Required ... Yes", "Air Freezing Index ... 2000", and "Mean Annual Temperature ... 50 F." The same section separately replaces Table R301.6 Minimum Roof Live Loads with a City-specific table: 30 lbs. snow load plus 15 lbs. dead load for pitched roof rafters of 4 inches per foot or greater, 30 lbs. snow load plus 20 lbs. dead load for flatter rafters, and 30 lbs. snow load plus 10 lbs. top-chord and 10 lbs. bottom-chord dead load for manufactured roof trusses.

TWO LAYERS MAXIMUM UNDER THE UNMODIFIED BASE 2021 IRC; THE CITY'S OWN AMENDMENT TOUCHES CHAPTER 9 BUT NOT THIS SECTION. Article XIV's amendment list (Sec. 6-402, Ord. No. 22-O-44, Section 7, 4-18-2022, read in full) adds exactly one Chapter 9 provision, "R901.2 Concealed areas. Roofing materials shall be removed down to roof deck in concealed areas," and does not touch R908.3.1.1, the roof re-cover section, at all. Under the unmodified 2021 International Residential Code, R908.3.1.1 bars a roof recover where, among other conditions, "the existing roof has two or more applications of any type of roof covering." One existing layer may be recovered; a second forces tear-off.

NOT AMENDED; THE UNMODIFIED 2021 IRC ROOF SHEATHING PROVISIONS APPLY. Article XIV's amendment list (Sec. 6-402, read in full, roughly sixty individual sections and tables) touches floor sheathing thickness (R503.2.1.1, R503.2.2, both three-quarter inch minimum) and a wall-stud spacing table (Table R602.3(5)), but no provision of Chapter 8 (roof-ceiling construction) or R803 (roof sheathing) appears anywhere in it. The base 2021 IRC's roof sheathing requirements therefore govern unmodified.

STATE 6.25 PERCENT ON MATERIALS ONLY, OWED BY THE CONTRACTOR, AT THE SUPPLIER'S OR THE CONTRACTOR'S OWN LOCATION -- NOT AT THE JOB ADDRESS. Illinois taxes a roof job as a construction contract rather than a retail sale: 86 Ill. Adm. Code 130.1940(c) provides that "a construction contractor does not incur Retailers' Occupation Tax liability as to receipts from labor ... and tangible personal property ... incorporated into a structure," and instead "incurs Use Tax on the cost price of the tangible personal property," with "roofing materials" named among the examples at 130.1940(c)(1). Repair and replacement are taxed identically: "Construct" is defined at 130.1940(a)(3) to mean "build, erect, construct, reconstruct, install, plant, repair, renovate or remodel." The combined rate that lands on the materials purchase is the one where the supply house or the contractor's own place of business sits, not the homeowner's address (86 Ill. Adm. Code 130.2075). The state rate has been 6.25 percent since January 1, 1990 (86 Ill. Adm. Code 130.101(c)(1)). For a Waukegan business location, SalesTaxHandbook lists a combined rate of 8.5 percent (6.25 percent state, 1.5 percent City of Waukegan, 0.75 percent Regional Transportation Authority); a second aggregator, SalesTaxGuide, lists 8.6 percent for the same ZIP code. Both are third-party mirrors, named here as such; the authoritative lookup, address by address, is the Illinois Department of Revenue's own MyTax Illinois Tax Rate Finder.
