Adopted code
"International Building Code- 2018 Edition" (listed as a helpful reference link on the Town's Building/Planning page).
Impact-resistant roofing
Not required — Nunn Municipal Code Section 15.04.120 adopts the 2018 International Residential Code by reference, chapters 1 through 43 inclusive plus appendix chapters H and M, as the town residential building code; Section 15.04.020 separately adopts the 2018 International Building Code. The Section 15.04.120 amendment list was read in full, running in code order from the Section R101.1 title amendment through the appendix Section AM103.1.3.2 amendment. It amends no section of Chapter 9, Roof Assemblies, so the adopted Chapter 9 stands as published, and neither it nor any town amendment requires impact-resistant roof coverings or names a UL 2218 or Class 4 standard. The Colorado Energy Office Statewide Building Code Adoption dataset, revised April 2, 2026, likewise reports a 2018 adoption for the Town.
Roof layer limit / recover
The Town's "2024-IRC Re-Roof-Guide," published by SAFEbuilt, Inc. (the Town's contracted building/inspection provider) and hosted on the Town's Building/Planning page, quotes "SECTION R908: REROOFING" as follows: "R908.3 Roof Replacement. Roof replacement shall include the removal of existing layers of roof coverings down to the roof deck: (Some exceptions may apply to your situation) ... 3. Where the existing roof has two or more applications of any type of roof covering." The same guide's FAQ states: "How many layers of roofing are allowed? No more than two (2) layers are allowed upon completion of installation."
Sales & use tax
4.90% combined (state 2.9% + Town of Nunn 2%; Weld County levies no county sales tax), per Colorado Department of Revenue form DR 1002 (rev. 06/19/19), which lists Nunn under State-Collected City Sales Taxes at 2% and does not list Weld County in its State-Collected Colorado County Sales Tax table (a county absent from that table has no county sales tax). No RTD/SCFD/RTA district applies to Nunn. Re-verified 2026-08-27 against the January 2026 edition of Colorado Department of Revenue form DR 1002, read from a rendered image of its tables rather than from extracted text: the state, county and city figures above match that edition exactly. Where the text above names the June 19, 2019 revision of DR 1002, that describes the edition the figure was originally taken from and is not a current citation.
