Town of Hugo, Colorado

Hugo, CO

Not required

The town's Information page states, under "When do I need a building permit?": "The subject matter of the adopted International Building Codes and appendixes includes comprehensive provisions and standards regulating the erection, construction, enlargement, alteration, repair, moving, removal, conversion, demolition, occupancy, equipment, use, height, area, and maintenance of all buildings and structures in the Town of Hugo and further provides for the issuance of permits and the collection of fees." Permit applications "may be acquired at the Town Hall." No roofing-specific permit language is published, so no roofing-specific requirement is asserted.

Ordinance No. 253 adopts by reference "the Land Development Code of the Town of Hugo, Lincoln County, Colorado, including the International Building Code, 2006 Edition, and the International Residential Code, 2006, Edition," covering zoning, building codes, subdivision regulations, and annexation. Ordinance No. 295 (first reading March 9, 2026; second reading April 13, 2026) adopts by reference "the 2025 Edition of the Colorado Wildfire Resiliency Code," added as Section 605 of Land Development Code Article IV, pursuant to the C.R.S. 24-33.5-1236 requirement that WUI jurisdictions adopt a code meeting or exceeding the state model.

Not required — The Town of Hugo's building-code authority was read in full through three instruments. Ordinance 253, adopted March 11, 2019, adopts the Hugo Land Development Code by reference, including the International Building Code and International Residential Code, naming the 2006 editions in its text; the Land Development Code the Town currently publishes as its code, updated May 13, 2024, states at Article VI, Section 601.1 that the 2018 editions of the International Building, Residential, Mechanical and Energy Conservation Codes with their appendices are adopted by reference, so the edition in force should be confirmed with the Town. Under either edition the answer here is the same: Section 601 adopts the codes by reference without amending any of their technical provisions, its remaining text addressing the building official, permit and inspection fees and penalties, and neither the 2006 nor the 2018 International Building or Residential Code itself requires impact-resistant roof coverings. Ordinance 295, adopted April 13, 2026, adds Section 605 adopting the 2025 Colorado Wildfire Resiliency Code, 8 CCR 1507-39, and designates the wildland-urban interface areas shown on the state Fire Intensity Classification map within the Town's boundaries; its four amendments touch only the code's title, enforcement agency and penalty sections. That code requires a Class A roof covering tested to ASTM E108 or UL 790 where 25 percent or more of the roof surface is replaced, at Sections 101.6 and 403.2, which is a fire classification independent of impact rating, and the code sets no impact-resistance requirement. Neither instrument requires impact-resistant roof coverings or names a UL 2218 or Class 4 standard.

Hugo's Land Development Code adopts by reference "without amending any of their technical provisions," and the Town's own instruments name both the 2006 and the 2018 International Residential Code, an ambiguity this record does not resolve. Both candidate editions agree on this point. The 2006 IRC Section R907.3, Re-covering versus replacement, provides: "New roof coverings shall not be installed without first removing existing roof coverings where any of the following conditions occur: ... 3. Where the existing roof has two or more applications of any type of roof covering." The 2018 IRC Section R908.3.1.1, Roof recover not allowed, provides the same trigger: "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." Under either edition, a third layer requires full tear-off.

Both candidate editions of the IRC agree, and the Land Development Code adopts by reference without amending this technical provision. Section R803.1, Lumber sheathing, sets a minimum net thickness of 5/8 inch for lumber roof sheathing at 24-inch rafter/beam spacing, rising to 1-1/2 inch tongue-and-groove at wider spacings with minimum bending strength/stiffness ratings, and bars spaced lumber sheathing in Seismic Design Category D2 -- identical values in the 2006 and 2018 editions. Wood structural panel sheathing must conform to DOC PS 1, DOC PS 2 or CSA O437 (2006 edition; the 2018 edition also permits CSA O325) with an approved grade mark, Exposure 1 or better where the underside is exposed, and be installed within the allowable spans of Table R503.2.1.1(1) or APA E30.

7.9% combined effective 2026-07-01: 2.9% Colorado state, 2% Lincoln County, 3% Town of Hugo. The Colorado Department of Revenue's "Sales Tax Rate Changes" notice effective July 01, 2026 lists "Hugo (Sales Tax Increase)" at a 3.00% sales tax rate and a 3.00% use tax rate, raising both from the 2% printed in the January 2026 DR 1002. Hugo's exemption codes (B: machinery and machine tools; K: renewable energy components) do not reach building or roofing materials, and the Town's use tax column names "Motor Vehicles, Building Materials" as taxable. No RTD, SCFD, RTA or other special district lists Lincoln County or the Hugo area in its DR 1002 boundary description.
