Tips

  • Solar carries the longer 10-14 business day Residential Permit review window, not the fast 24-72 hour Counter Permit track most other standalone trade permits use — budget accordingly.
  • The Town's PV Solar Submittal Checklist is branded and returned via ProCode's Johnstown regional office (39 S Parish Ave #220, Johnstown, CO 80534, (970) 305-3161, email@procodeinc.net) — confirm submission channel directly, since this differs from the Town's own bldgdept@millikenco.gov address used for other permit types.
