An Improvement Location Certificate (ILC) is an inspection of a parcel by a licensed surveyor to determine possible encroachments or other matters that could be adverse from a land surveying standpoint. ILCs are often if not always required on the closing of a property or at the completion of any construction (improvements) on a property, normally residential in nature.
An Elevation Certificate compares a property’s elevation data to the Base Flood elevation data. A licensed Surveyor or Engineer makes actual field measurements using survey instruments and techniques to obtain the property’s elevation data and then transfers that data to the Certificate which is an official form of the National Flood Insurance Program. Refer to our FEMA elevation page for more info.

One would need to present the final as-built survey to get a Certificate of Occupancy for the building.
