Improvement Location Certificate

An ILC's primary function is to certify where the improvements on the property are located and indicating any overlaps by or on the property. It also will indicate if there is any apparent sign or evidence of any easement or crossing. An ILC will show the improvements relative to the platted boundary and monuments (property corners) found. Platted easements and building envelopes will be shown on the document (but generally not standard setback requirements defined by county or city zoning).

ILCs may be required by the county or town government to verify setback requirements are being met during various phases of construction.

The improvement location certificate is another method of describing and approximately locating property, which is often required by lenders and insurance companies. It offers certain reasonable assurances regarding potential boundary or encroachment problems that may affect their interests. It also illustrates the location of improvements and conditions of the property. However, it is based on assumptions regarding boundary location and is not a precise survey. The improvement location certificate is typically used in the purchase of single family residential property located within the established subdivided urban and suburban areas of Colorado.
