How do I find what year my house was built?

The County website has a system that will locate your property by the address you provide.  Go to the County website:  http://jocogov.org.  On the right-hand side of the website (just beneath the "Search" button) you will see a section titled "Location Maps & Info".  Type in the street address of your property.  Do not use punctuation.

Under the "Property Description" you will see "Year Built".
