Published scheduling rules

The City publishes NO numeric plan-review turnaround (days or weeks) for any standard building-permit category anywhere on its site — not on the Building Division page, the Do I Need a Building Permit page, the Roofing Guidelines page, the Building Inspection Scheduling page, the 2026 fee schedule, or the Building Permit Reports archive. Colorado is home-rule with no statewide clock, and every permitType in this file is honestly null/unverified with a documented chase trail rather than an invented figure. (General)
