THE 2021 INTERNATIONAL RESIDENTIAL CODE AS AMENDED BY ARM 24.301.154, ADOPTED BY NAMED, DATED ORDINANCE AND EXPRESSLY EXTENDED TO ONE- AND TWO-FAMILY DWELLINGS. City Code 8-1-1, Building Codes Adopted (Ord. 2007-3, 4-16-2007; amd. Ord. 2010-8, 9-20-2010; Ord. 2015-1, 2-2-2015; Ord. 2020-1, 1-21-2020; Ord. 2021-1, 5-3-2021; Ord. 2021-4, 8-16-2021; Ord. 2022-10, 7-5-2022), reads in relevant part: "Pursuant to Montana Code Annotated section 50-60-301 and the Administrative Rules of Montana, chapter 24, the city adopts the following codes: ... B. International Residential Code: The International Residential Code, 2021 edition, as amended by ARM 24.301.154." The same section closes: "These codes are applicable to all buildings within the building code enforcement area of the city, including, but not limited to, residential buildings containing less than five (5) dwelling units or their attached to structures, and farm or ranch buildings, and any private garage structures used only for the owner's own use as provided by Montana Code Annotated section 50-60-102(1)(a)." That is an express extension in the statute's own words, which is what Montana's "specifically applicable" test (MCA 50-60-102(1)(a); ARM 24.301.201(1)) requires. Title 8, Chapter 1 contains exactly this one section; it is the whole of the adoption, with no separate amendment list. THE ADOPTION IS FROZEN AT A NAMED EDITION, NOT FLOATING - but it happens to match the current state edition today. Unlike a jurisdiction whose ordinance tracks the department's current codes automatically, Belgrade names "2021 edition" and has re-enacted the reference by amendment as recently as Ord. 2022-10 (7-5-2022). ARM 24.301.202(1) requires a certified jurisdiction to conform to the department's current codes within 90 days of a change notice, so if the department were to move off the 2021 IRC, Belgrade's ordinance would need its own further amendment to keep pace; this record states today's text and does not predict that. A DISCLOSURE, NOT RESOLVED. The City's own Building Permit Guidelines (updated 9/13/2022) open by stating dwellings "are required to be built in accordance with the 2021 International Residential Code (IRC)," matching City Code 8-1-1, but a later section of the same document says plan-review items are "from the 2018 International Residential Code (IRC) as amended by the State of Montana unless otherwise noted." This record does not decide which the document means; it states the codified ordinance's own 2021 text as the operative fact and discloses the guidance document's inconsistency rather than silently picking a side.

Required — DEFAULT TRUE, AS A POINTER TO THE UNAMENDED BASE 2021 IRC, NOT A QUOTED FIGURE. Belgrade adopts the 2021 International Residential Code as amended by ARM 24.301.154 (City Code 8-1-1). That state amendment rule makes no change to the base code's drip-edge provision in Chapter 9; its only Chapter 9-adjacent amendment is the ice-barrier substitution described in this record's ice-and-water-shield field. Belgrade's own single-section adoption ordinance adds nothing on the point either. This record does not repeat the base code's operative drip- edge text, since nobody on this project has opened it against Belgrade's own instrument; it points to the unamended 2021 IRC chapter as the applicable provision. About drip edge

Required — REQUIRED STATEWIDE BY A STATE AMENDMENT THAT REPLACES THE MODEL CODE'S GEOGRAPHIC TRIGGER WITH THE WHOLE STATE, AND BELGRADE'S OWN GUIDANCE SAYS THE SAME THING IN PLAIN WORDS. ARM 24.301.154(23), which Belgrade adopts by City Code 8-1-1 ("as amended by ARM 24.301.154"), reads in full: "Subsection R 905.1.2 is amended by deletion of the language 'areas where there has been a history of ice forming along the eaves causing a backup of water as designated in Table R301.2' and insert 'the State of Montana.'" That deletes the model code's local ice-damming finding and substitutes the entire state, so the ice-barrier underlayment requirement applies in Belgrade with no local history-of-ice-damming finding needed. The City's own Building Permit Guidelines corroborate it in plain language, requiring a plan submittal to "Show roof covering materials. Ice barrier required." About ice & water barrier

Not required — NOT REQUIRED BY THE STATE'S BUILDING-CODE AMENDMENT RULES OR BY BELGRADE'S OWN ADOPTION ORDINANCE. The state's amendment rules that reach a house's roof - ARM 24.301.154 (the IRC packet) and ARM 24.301.146/.142 (the IBC amendments Belgrade also adopts) - were counted for "UL 2218," "Class 4," "Class IV," "impact" and "hail"; each returns zero across the IRC packet, and the one "impact" hit in the IBC amendments is the English word ("does not negatively impact"), not a code requirement. Montana's ceiling statute (MCA 50-60-301(2)(a)) bars a city, county or town from adopting or enforcing a building code "more stringent than the building code adopted by the department," so Belgrade could not add an impact-resistance requirement even if it wished to, and its own single-section adoption ordinance (City Code 8-1-1) adds no such requirement in fact. An insurer's premium discount for an impact-rated shingle is not a code mandate.

NO DOLLAR OR SQUARE-FOOTAGE THRESHOLD IS PUBLISHED, AND THE PERMIT ANSWER RESTS ON THE CITY'S OWN SCOPE STATEMENT RATHER THAN A ROOFING-SPECIFIC LINE. The City's own Building page states plainly that the Building Department "issues building permits for new construction and additions or alterations to existing buildings within the City limits" - a roof covering replacement is an alteration to an existing building on its face, and no carve-out for roofing or for repair work appears on that page or in the Building Permit Guidelines. The Master Fee Schedule prices a Building Permit at Valuation x 0.0088 with no minimum-valuation exemption listed for that category. The Building Permit Guidelines (updated 9/13/2022) require, as a plan-submittal item for one- and two-family dwellings and townhouses, that a submittal "Show roof covering materials. Ice barrier required," which confirms roof covering is within the Building Department's plan-review scope; that document addresses new construction and does not itself state a separate reroof threshold. Nothing here should be read to say Belgrade WOULD exempt a small repair - only that no such exemption has been found in the materials reviewed. Call the Building Department at 406-388-3560 to confirm treatment of a job at the margin.

NOT ESTABLISHED FOR BELGRADE. Montana's amendment rules state no statewide wind speed - "wind speed" returns zero occurrences across the state's IRC, IBC and related amendment rules - and leave the ground snow load to the building official inside a certified jurisdiction like Belgrade rather than publishing a table (ARM 24.301.154(5), replacing IRC R301.6 Roof Load: "Snow loads shall be determined by the building official" inside a certified jurisdiction). The City's own Building Permit Guidelines require a submittal to include "roof truss engineering/snow load and wind load information" and refer to "Belgrade's snow load" as a known design value, but no wind speed or snow load figure was found published on the City's own site within this session. This field is left unset rather than guessed; ask the Building Department for the current design values at 406-388-3560.

THIS RECORD DOES NOT STATE A LAYER CLASSIFICATION. Belgrade adopts the 2021 International Residential Code as amended by ARM 24.301.154 (City Code 8-1-1). That state amendment rule was read in full and makes no amendment naming an R908 section number or a reroofing/recover provision anywhere in its text, and City Code 8-1-1 - the whole of Belgrade's Title 8, Chapter 1 adoption - adds nothing of its own on the point either. Rather than borrow a layer count from the base code that nobody on this project has read against Belgrade's own instrument at its 2021 edition section numbering, this record leaves the question open and points to the unamended 2021 IRC roof-assemblies chapter as the place the answer would come from.

NO LOCAL RULE, AND THE STATE'S OWN AMENDMENT RULE MAKES NO CHANGE TO ROOF SHEATHING. Belgrade adopts the International Residential Code, 2021 edition, "as amended by ARM 24.301.154" (City Code 8-1-1). That state amendment rule was read in full and makes no amendment to IRC Chapter 8 or to any roof-sheathing provision - "sheathing" and anchored patterns for an R8xx section number each return zero occurrences across its text, as does "Chapter 8." City Code 8-1-1 is the whole of Belgrade's Title 8, Chapter 1 adoption; it adds nothing of its own on sheathing. So the base 2021 International Residential Code's roof sheathing provisions apply in Belgrade unmodified - this record points to that chapter rather than restating figures nobody on this project read against Belgrade's own instrument.

NONE. MONTANA HAS NO GENERAL SALES TAX, AND THE STATE'S OWN REVENUE DEPARTMENT SAYS SO DIRECTLY: "Montana does not have a general-use sales tax." A Belgrade reroof carries no state or local sales tax on materials or labor on that basis. TWO NARROW TAXES EXIST AND NEITHER REACHES AN ORDINARY RESIDENTIAL REROOF. Belgrade is not one of the ten communities that levy a local resort tax (Red Lodge, Virginia City, West Yellowstone, Whitefish, Big Sky, Cooke City, Craig, Gardiner, St Regis, Wolf Creek), and even in those, MCA 7-6-1503(2) taxes only lodging, restaurant/food-service, alcohol-by-the-drink, and destination-recreation sales, while MCA 7-6-1501(3) expressly excludes "hardware supplies and tools" and "necessities of life" from the "luxuries" a resort tax can reach. Separately, MCA 15-50-205(1) and 15-50-101(3)(a) impose a 1% Contractor's Gross Receipts Tax, but only on a "public contractor" on a public construction contract exceeding $80,000 - it does not reach a private residential job.
