No. 317 6-20-2019); 2018 International Residential Code (IRC), chapters 1-43 and appendix chapters H and M, adopted by reference — NMC 15.04.120, as amended (Ord.

No. 237, 263, 317); 2018 International Existing Building Code (IEBC), chapters 1-16, adopted by reference — NMC 15.04.130 (Ord. No. 263 5-3-2007; Ord. No. 317 6-20-2019); 2018 International Property Maintenance Code (IPMC), chapters 1-8, adopted by reference — NMC 15.04.150 (Ord. No. 317 6-20-2019); 2018 International Swimming Pool and Spa Code (ISPSC), chapters 1-11, adopted by reference — NMC 15.04.160 (Ord. No. 317 6-20-2019); 2012 International Energy Conservation Code (IECC), chapters 1-5, adopted by reference as the town energy conservation code — NMC 15.04.140 (Ord. No. 317 6-20-2019); IBC section 1301.1.1/101.4.6 and IRC chapter 11 are both explicitly amended to substitute the 2012 IECC as well; National Electrical Code, 2002 edition, adopted by reference — NMC 15.04.040 (codified text, unamended since original Code 2002 codification). NOTE: this is the currently codified NEC edition in the 2024 Nunn Municipal Code as republished by Ordinance No. 326 (adopted 6-20-2024, adopting/enacting the Municipal Code by reference). However, SAFEbuilt's own current 'Photovoltaic System Submittal Requirements' handout (the Town's contracted plan-review/inspection agency) states 'Applicable current codes are the 2020 NEC, 2018 International Codes' — a direct discrepancy between the codified 2002 NEC text and SAFEbuilt's operational reference. The governing citation is the codified 2002 NEC per NMC 15.04.040 pending confirmation from the Town.; Chapter 15.16 (Energy Efficiency Construction) of the Nunn Municipal Code additionally references the 1977/1978 Colorado Model Energy Efficiency Construction and Renovation Standards for Nonresidential Buildings and the companion Colorado Recommended Energy Conservation 'Performance' Code for Residential Buildings — these appear to be vestigial/superseded provisions retained from the original 2002 code codification and predate the town's adoption of the 2012 IECC at NMC 15.04.140 (2019), which is the governing energy standard.. Local amendments apply — see the Nunn overview page for the full list.
