Do you need a permit to replace a roof in Hot Sulphur Springs, CO?

Adopted code

Town of Hot Sulphur Springs (Grand County Building Department)

Yes, a permit is required to replace a roof in Hot Sulphur Springs, CO, issued by Town of Hot Sulphur Springs (Grand County Building Department). Per the Town's "New Single-Family Home Building Permit Guide" (Updated November 2023): "The Town has contracted with the Grand County Building Department to review and issue building permits and conduct inspections." The Town performs an initial zoning-compliance intake and then forwards applications to Grand County, which reviews plans "against the adopted building codes" and issues the permit; the Grand County Building Department office is itself located in Hot Sulphur Springs (308 Byers Ave). That guide is scoped to new single-family homes and explicitly states it is "NOT intended to provide information on projects such as an addition, roof repair, demolition, electrical or plumbing work," so it does not itself state whether reroofing requires a permit. Grand County's own "GRAND COUNTY ROOFING GUIDELINES" document (a Building Division roofing-permit worksheet with fields for contractor name/signature, job site address, quantity of squares, valuation, and percent of waterproof membrane) states: "If the project is a re-roof where the old roofing will not be removed, a maximum of two layers of roofing will be allowed (One layer old, one layer new). Ice and water shield is not required in these cases," plus metal-roof snow-retention and vent-pipe language — the existence of this contractor-signature permit worksheet indicates reroofing is a permitted activity under the county process that serves the Town, though neither the Town nor the County publishes an outright statement that a permit is required for reroofing; confirm with the Grand County Building Department before starting work. Neither the Town nor the County publishes a contractor licensing or registration requirement applicable to roofers.

Permit process note
Per the Town's "New Single-Family Home Building Permit Guide" (Updated November 2023): "The Town has contracted with the Grand County Building Department to review and issue building permits and conduct inspections." The Town performs an initial zoning-compliance intake and then forwards applications to Grand County, which reviews plans "against the adopted building codes" and issues the permit; the Grand County Building Department office is itself located in Hot Sulphur Springs (308 Byers Ave).

Neither the Town nor the County publishes a contractor licensing or registration requirement applicable to roofers.
Adopted code
Grand County's Codes & Amendments page states codes "Effective July 1, 2026": "2021 Building Codes and the 2025 Colorado Wildfire Resiliency Code with Local Amendments," comprising the 2021 IRC and 2021 ICC Codes (IBC and related standards) plus the 2025 Colorado Wildfire Resiliency Code, each with Grand County Local Amendments (Resolutions No. 2026-4-11 and No. 2026-6-9). The same page states that, prior to that effective date, "2015 International codes remain in effect," including the IRC, IBC, Mechanical, Plumbing, Fuel Gas, and Energy Conservation codes, plus the 2023 National Electric Code and 2015 International Fire Code, all with local amendments. This is Grand County's own adopted-code page, not a Hot Sulphur Springs-specific ordinance, but it governs permits issued for the Town under the Town/County contract described above.
Ice & water shield
Required — Grand County's building code, adopted by the Town by reference (Resolution 2018-5-31 / Ordinance No. 21, Exhibit A, amending the 2015 International Residential Code), amends Section R905.1.2: "An ice barrier that consists of an approved self-adhering polymer modified bitumen sheet shall be used in lieu of normal underlayment on all sloped roofs. This ice dam protection underlayment shall be installed from the eaves to a point 6 feet inside the exterior wall line of the building and 24 inches from the center line of all valleys, fully adhered to the substrate on all habitable structures." The only exception is for detached accessory structures with no conditioned floor area. About ice & water barrier
Impact-resistant roofing
Not required — The Town of Hot Sulphur Springs adopts the 2015 International Building Code and the 2015 International Residential Code, codified through Ordinance No. 2022-06-16-412 enacted June 16, 2022, and the Colorado Energy Office's statewide building code adoption record lists the same 2015 edition. The building chapter and its amendment lists were reviewed in full. The chapter contains no roof covering requirement, no impact resistance requirement and no reference to UL 2218 or Class 4 roof coverings.
Roof layer limit / recover
Which rule governs depends on an unresolved question about Grand County's own adoption, so both branches are stated. Grand County's Codes & Amendments page says "Grand County has adopted 2021 Building Codes and the 2025 Colorado Wildfire Resiliency Code with Local Amendments, effective July 1, 2026," and then heads a list of 2015 codes with "The following codes are currently in effect within the county." Both statements appear on the page at once. UNDER THE 2015 PACKAGE, Grand County amends IRC Section R908.3, Recovering versus replacement, to read: "New roof coverings shall not be installed without first removing all existing roof coverings where any of the following conditions occur: 1. 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. 2. Where the existing roof covering is wood shake, slate, clay, cement or asbestos-cement tile. 3. Where the existing roof has two or MORE THAN ONE applications of any type of roof covering. 4. For asphalt shingles, when the building is located in an area subject to severe hail damage according to Figure R903.5." (The capitalisation is the County's own, marking amended text; condition 3 is drafted as quoted.) Condition 4 means a tear-off can be required for asphalt shingles on the first layer, independent of layer count. UNDER THE 2021 PACKAGE, the County's local amendments contain no amendment to R908 at all, so the base 2021 IRC governs: Section R908.3 provides that "Roof replacement shall include the removal of existing layers of roof coverings down to the roof deck," and Section R908.3.1.1 that "A roof recover shall not be permitted where any of the following conditions occur: ... 3. Where the existing roof has two or more applications of any type of roof covering." The two branches differ, so no single layer count is asserted here; confirm with the Grand County Building Department which package applies to the permit at hand.
Sales & use tax
Hot Sulphur Springs' combined sales tax rate is 8.20%: the Colorado state rate of 2.9%, plus the Grand County rate of 1.30%, plus the Town's state-collected city rate of 4%.
