Use Permits for Title Transfer/Selling a Property
If you are selling a property with a home in unincorporated Gilpin County, you must have the property's septic system inspected and obtain a Use Permit prior to going under contract. Use Permits are valid for 6 months. Failure to obtain a Use Permit can subject you to a daily accruing penalties under Colorado law.
There are two separate applications now. One for conventional treatment level systems (TL1) and one for higher level treatment systems (TL2+) that require the property buyer or title grantee to obtain a maintenance contract and Operating Permit. It is your responsibility as the seller/title grantor to inform the buyer of these requirements. Failure to do so can result in enforcement action against you.
