Rooftop / Ground-Mounted Solar Photovoltaic Permit in Nunn, Colorado

Required for solar panel installation or replacement in Nunn. SAFEbuilt (the Town's contracted plan-review/inspection agency) publishes a dedicated Photovoltaic System Submittal Requirements packet specifying current applicable codes as the 2020 NEC and 2018 International Codes, plus structural engineering letter requirements for roof-mounted and ground-mounted systems.

When you need this permit

  • Permit application (emailed to the Town or submitted online) must fully describe the work, with valuation based on total cost to the customer (contract price) including materials and labor regardless of who supplies them
  • A separate plan review — and potentially a separate permit — is required for each building/address on a property
  • Per SAFEbuilt's Photovoltaic System Submittal Requirements packet, applicable current codes are the 2020 NEC and 2018 International Codes (this is SAFEbuilt's own stated reference and differs from the 2002 NEC edition still shown in the codified Nunn Municipal Code text at NMC 15.04.040 — see localAmendments note)
  • Roof-mounted systems require a structural engineer's stamped letter addressing added roof weight and additional wind load from the panels, designed to a minimum ground snow load of 30 psf, wind speed of 115 mph Vult, Exposure C, and Seismic Design Category B, including roof connection/embedment type
  • Ground-mounted systems require an engineer-stamped letter for system support and wind load, using the same 30 psf snow load / 115 mph Vult / Exposure C / Seismic Design Category B design basis

Fee schedule

Building/Electrical Permit Fee (SAFEbuilt-calculated, valuation-based)Nunn's own Town Board-set/SAFEbuilt-calculated fee remains a per-application, not a published-table, mechanism (confirmed 2026-07-20 by re-checking the Building/Planning page and SAFEbuilt's Photovoltaic System Submittal Requirements packet). However, Colorado electrical inspections are a matter of statewide concern under C.R.S. § 12-23-117 — no local government, including Nunn, may charge more than 1.15x the DORA State Electrical Board's own fee schedule for the electrical scope, or impose any other electrical fee or charge. That statewide base schedule (townoflarkspur.org/media/2901, hosted live by the Town of Larkspur, CO, printed with DORA's own Denver address/phone) sets Section B "Commercial and other fees" (which Larimer County's current Table 1-E, larimer.org/sites/default/files/2020_electrical_fee_table.pdf, explicitly confirms includes solar) at $100 base for valuation up to $2,000, plus $10/thousand above. This governs the ceiling and formula for whatever SAFEbuilt ultimately invoices for Nunn's electrical scope.
Statewide electrical component follows C.R.S. § 12-23-117: base fee ~$100-$120 for job valuation up to $2,000, plus roughly $10-$11.50 per $1,000 of valuation above that, scalable up to 1.15x by the local government — capped in aggregate at $500 residential/$1,000 commercial by C.R.S. § 24-48.5-113

Tips

  • A separate structural engineer's stamped letter is required for BOTH roof-mounted and ground-mounted systems in Nunn — budget for this cost and lead time before submitting.
  • SAFEbuilt cites the 2020 NEC as the applicable current electrical code for solar work, which is newer than the 2002 NEC edition still shown in the codified Nunn Municipal Code text — confirm directly with SAFEbuilt/the Town Clerk which edition will actually govern your specific inspection.

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.

Yes, though the content differs: SAFEbuilt's Photovoltaic System Submittal Requirements packet requires an engineer-stamped letter for ground-mounted systems addressing support and wind load (30 psf snow load, 115 mph Vult, Exposure C, Seismic Design Category B), while roof-mounted systems require a letter addressing added roof weight, wind load, and the roof connection/embedment method, using the same design-load basis.
