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. 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. Flagged honestly rather than resolved by assumption; 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Colorado Recommended Energy Conservation 'Performance' Code for Residential Buildings — these appear to be vestigial/superseded provisions retained from the original 2002 code codification and predate the town's adoption of the 2012 IECC at NMC 15.04.140 (2019); not applied as the governing energy standard in this file.. Local amendments apply — see the Nunn overview page for the full list.

Only if the scope adds a structure or addition over 120 square feet. A straightforward interior basement finish with no exterior footprint change would not typically trigger Planning Board review, but would still require a building permit and SAFEbuilt plan review/inspection.
