Fee schedule

Town Admin Fee (Building Permit, plan review required) + Use TaxCLOSED 2026-07-23 on a live primary source: the Town of Nunn's own 'Fee Schedule, Effective January 22nd, 2026' (PDF, linked live from the Town homepage — not located in the prior 2026-07-06 chase) lists under 'Building Permits': 'Admin Fee (permits requiring plan review) $75.00' and 'Use Tax on all Building Permits 2%'. New residential construction always requires SAFEbuilt plan review per this file's own requirements, so the plan-review tier governs. This is the Town Clerk's own flat administrative processing fee and use-tax rate — charged IN ADDITION TO, not instead of, SAFEbuilt's separate valuation-based plan-review/inspection fee, which SAFEbuilt calculates per application and remains unpublished as a table (re-checked 2026-07-23: no SAFEbuilt rate table specific to Nunn is published anywhere live). The prior 'no published fee schedule exists' finding is corrected for the Town's own admin-fee/use-tax component; it remains accurate only for SAFEbuilt's per-application valuation-based charge.
$75.00 flat Admin Fee (permits requiring plan review), plus 2% Use Tax on all Building Permits

One-half the original permit fee (if within 1 year of suspension/abandonment, no plan changes); full new fee if lapsed longer

Tips

  • Budget calendar time for Planning Board approval BEFORE SAFEbuilt plan review even begins — paperwork is due 6 days ahead of the first-Thursday-of-month meeting, and the applicant must personally attend or the item gets tabled to the following month.
  • Because SAFEbuilt (not town staff) performs plan review and all inspections, expect a genuinely separate scheduling and communication channel from the Town Clerk's Office — inspection requests go to windsor@safebuilt.com or 970-674-1036, not to Town Hall.
  • There is no published fee schedule — get a written fee quote from the Town Clerk's Office or wait for the SAFEbuilt-calculated invoice before committing to a budget.
  • Foundation designs must be stamped by a Colorado-registered design professional and based on an engineer's soils report — this is a harder requirement than a simple prescriptive IRC foundation table in many peer small towns.
