Nunn building permits

Requirements

• Planning Board approval required before the application is forwarded to SAFEbuilt for plan review; paperwork must be submitted to Town Hall at least 6 days before the Planning Board's first-Thursday-of-the-month, 6:00 p.m. meeting, and the applicant must personally attend
• Plans must comply with the 2018 IRC as locally amended and meet Nunn's Climatic and Geographic Design Criteria: 30 psf ground snow load, 115 mph wind design speed (Exposure C, Seismic Design Category B), 30-inch minimum frost depth, ice barrier underlayment required
• Foundation design and construction drawings must be stamped by a Colorado-registered design professional, based on an engineer's soils report (firm name, design location, and soils-report number noted); a site certification by a Colorado-registered design professional is required for setback verification
• One set of plans (site plan, floor plan showing square footage by level/garage/deck/porch/crawl space, and structural/electrical/mechanical/plumbing plans as applicable) submitted to the Town Clerk's Office or emailed to kendra.minch@townofnunnco.gov
• Once returned from SAFEbuilt, the Town emails an invoice with assessed fees; payment (in person or by phone) and authorization must be complete before work may begin
• All inspections are performed by SAFEbuilt, not the Town; the owner/contractor is responsible for scheduling inspections directly with SAFEbuilt
• No distinct commercial-building-permit or tenant-improvement (TI) permit exists in Nunn: this same process, form, and fee structure is also used for new commercial/industrial construction and tenant-finish build-outs. The Town's own 'Building Permit Application' PDF (the identical form cited above) has a 'Proposed Use' section listing 'Commercial/Industrial — Shell Only / Tenant Finish' as a checkbox option directly alongside 'Residential: One Family / Multi Family' — confirming commercial and TI scopes route through this exact undifferentiated intake. Nunn Municipal Code Chapter 15.08 (Building Permits) itself is occupancy-agnostic: NMC 15.08.020(a) requires a permit for 'any building or structure, as defined by the building code for the town,' with no separate commercial process, fee schedule, or application named anywhere in Chapter 15.08. NMC Title 17 does establish a 'C Commercial District' (Ch. 17.24) and 'I Industrial District' (Ch. 17.28) at the zoning level, so commercial construction is a real, contemplated land use in Nunn — but no distinct commercial-permit type, admin-fee tier, or review-timeline SLA is published anywhere (checked the Building/Planning page, Chapter 15.08 in full, and the Town's 2026 Fee Schedule, which names only 'Admin Fee (permits requiring plan review) $75.00' and 'Admin Fee (One Stop permits) $50.00' under 'Building Permits,' with no commercial-specific line item). The 2018 IBC (adopted at NMC 15.04.020) would substantively govern a commercial/industrial occupancy's plan review versus the 2018 IRC for residential, but the intake process, application form, and Town-set admin-fee/use-tax structure are identical regardless of occupancy classification.

• All inspections are performed by SAFEbuilt, not the Town; the owner/contractor is responsible for scheduling inspections directly with SAFEbuilt
• A commercial structure that lacks a permanent heating system, insulation, or year-round usable plumbing is carved out as its own exception to the 'low energy buildings' provision of the Town's adopted energy code (2012 IECC, NMC 15.04.140, amending IECC section 101.5.1 to add this exception)
• Electrical and plumbing contractors on a commercial project must hold an active Colorado DORA state license, verified by the Town before the application is accepted, per the Town's Electrical/Plumbing License Contemporaneous Review Guidelines implementing C.R.S. 12-115-120 as amended by HB19-1086

Fee schedule

Requirements

• Electrical-only permit applications must list the electrician's Colorado DORA state electrical license number

• SAFEbuilt inspectors may, at their discretion, verify electrician identity at any inspection (not only rough/final) and may fail an inspection if unverifiable
• Codified governing standard is the National Electrical Code, 2002 edition (NMC 15.04.040); note SAFEbuilt's own current Photovoltaic System Submittal Requirements handout instead cites the 2020 NEC as the applicable current code — this discrepancy between the codified text and the contracted reviewer's operational reference is unresolved

Fee schedule

Requirements

• Neither the Town of Nunn nor the Nunn Fire Protection District publishes a standalone fire sprinkler or fire alarm permit type, application, fee schedule, or review process
• NMC 15.04.060 (Title 15, Building Code chapter) is expressly labeled 'Reserved for fire code adoption' — the Town has adopted no International Fire Code edition of its own
• Fire protection for the Town of Nunn is provided by the Nunn Fire Protection District, a volunteer department headquartered at 487 Logan Avenue (5th and Logan), Nunn, CO — contact 970.897.2329 / nunnfire@ezlink.com — confirmed via the Town of Nunn's own Fire Department and Utilities and Service Providers webpages; the district publishes no independent.gov website, application, or fee information of its own
• Two-family dwellings (duplexes) built in Nunn require an automatic residential fire sprinkler system under IRC Section R313.2 as locally amended (NMC 15.04.120) — single-family dwellings are exempt from this local amendment, and townhomes remain governed by the unamended IRC R313.1 sprinkler requirement; this requirement is implemented through the standard Building Permit (Town Clerk's Office → SAFEbuilt) process for the underlying duplex construction, not a separate sprinkler-specific permit
• Confirm any commercial fire alarm or fire sprinkler system project with both the Town Clerk's Office (970-897-2385 / kendra.minch@townofnunnco.gov) and the Nunn Fire Protection District (970.897.2329) before design — neither publishes a submittal checklist, plan-review process, or fee for these systems

Required documents

• OptionalBuilding Permit Application (if sprinkler/alarm work accompanies an underlying construction permit)The Town's standard generic Building Permit Application, submitted to the Town Clerk's Office; no sprinkler/alarm-specific application is published

Fee schedule

Requirements

• NMC 15.08.010: it is unlawful to 'use, or change the use of any building or other structure' within town limits without a building permit — a change of use requires a permit even absent new construction
• The Town's own Building Permit Application form states verbatim: 'Any change in the use or occupancy of the building must be approved prior to proceeding with consruction [sic]' — approval must be obtained before the new use/occupancy proceeds
• No dedicated 'change of use' checkbox exists on the application: the 'Type' field offers only New Build / Addition / Remodel / Other, and 'Proposed Use' offers Residential (One Family / Multi Family) or Commercial/Industrial (Shell Only / Tenant Finish); a change-of-use application marks 'Other' and describes the change under 'Description of Work'
• Substantively governed by Chapter 10 ('Change of Occupancy') of the 2018 International Existing Building Code, adopted by reference at NMC 15.04.130, chapters 1 through 16 inclusive, with no local amendment to Chapter 10 specifically (confirmed by reading NMC 15.04.130 in full: its only three amendments concern fire-code cross-references, the code title, and moved-structure conformance)
• At the zoning level, NMC 17.40.040 (Change in use) prohibits changing a legally nonconforming use to a use of lower or less restrictive classification; a nonconforming use may be changed only to a use of the same or higher classification
• As with all Nunn building permits, the application and any supporting description are submitted to the Town Clerk's Office (or emailed to kendra.minch@townofnunnco.gov), then forwarded to SAFEbuilt for review
• Nunn has no distinct commercial-building or tenant-improvement (TI) permit type either (see also the residential-building-permit entry) — commercial/industrial 'Shell Only' or 'Tenant Finish' scopes, including any accompanying change of use, are processed through this same generic Building Permit Application

Required documents
