Since 2015, Colorado now requires that when a property that is on a septic system sells, the septic system must be checked out by an approved vendor. This is a 2 part process. Once this has been completed, you will also need to provide an Acceptance Document Letter at closing which verifies that your septic system was checked out and accepted by the Health Department.
This is not an option, it is required in order to sell a property with a septic system. Below are links to the website, a list of approved vendors and how to obtain your acceptance letter for your closing. If have any other questions or to verify you are obtaining the correct report, you can call El Paso County Health Department at: 719.578.3100.
