Tips

  • Basement finishes, kitchen/bath remodels, and additions all fall under 'Building Residential Alteration' in eTRAKiT — pick the correct subtype (Addition vs. Remodel) when applying.
  • Budget for an asbestos survey if disturbing more than 32 sq ft of interior finish in an existing structure — required by the State of Colorado before renovation work in older buildings.
  • Additional plan review at $65/hour (4-hour minimum) applies for changes or revisions to already-approved plans — get your initial submittal complete to avoid this.
