Improvement Location Certificate (ILC) Optional LinkScape™ Interactive Upgrade
An Improvement Location Certificate (ILC) is a document prepared by a licensed professional land surveyor to show the location of existing improvements on a parcel relative to apparent property boundaries and to identify any visible encroachments or other matters of record.
Per the interpretation of the State Board of Licensure for Architects, Professional Engineers, and Professional Land Surveyors under section 38-51-108, C.R.S., ILCs are limited to use in real estate transactions only. Because ILCs are legally deficient for precisely determining property boundaries, they shall not be relied upon for the establishment of fences, buildings, or other future improvements.
Measurements on an ILC represent approximate record positions based on available data and field observations; these are provisional and may differ from a full boundary resolution. Unlike a land survey plat or improvement survey plat, an ILC is not intended to establish deed lines with boundary survey precision.
ILCs are commonly required by lenders, title companies, and municipalities in connection with property purchases, sales, refinancing, or certain permitting processes. They often help identify potential issues—such as encroachments or discrepancies—that may warrant a more detailed survey, such as an Improvement Survey Plat (ISP).
