Improvement Location Certificate (ILC)

You should have been given this information when you applied for a  building permit. The ILC can be approved as soon as the foundation is  dug and the form completed by your surveyor. The ILC must be a stamped  copy from a surveyor, showing boundary lines and placement of the new  foundation. The following situations require an ILC:

  • New  Structures (Plains): Lots less than 8,000 square feet; lots with  proposed setbacks of 5 feet or less; lots where a proposed setback is  less than 3 feet from the required minimum setback for the applicable  zone district; hazardous site conditions (geologic, floodplain).
  • New  Structure (Mountains): Lots of 1 acre or less; lots with proposed  setbacks of 10 feet or less; lots where a proposed setback is less than 5  feet from the required minimum setback for the applicable zone  district; hazardous site conditions (geologic, floodplain).
  • Additions (Plains & Mountains): Required for all additions which are subject to the same conditions noted above.
  • All variances

A  faxed copy is accepted under certain conditions: We must be able to  read and scale the faxed copy, and they must be stamped copies. If we  cannot read or scale it, or if it is not stamped, we will not be able to  sign-off for inspections to proceed. We must have the original mailed  or delivered to us for the permanent building permit file.
