Tips

  • Longmont's demolition fees are notably low flat rates ($50 minor interior / $100 major building) compared to many jurisdictions' valuation-based demolition fees — confirm with Building Services whether any additional utility-disconnect or bonding requirements apply to your specific project, as those were not found published alongside the flat fee.
