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. Failure to obtain a Use Permit prior to the date of a covered transaction can subject you to daily accruing penalties under Colorado law. 

Do you need to obtain a use permit when:

  1. You are selling a home in unincorporated Gilpin County? Yes. 
  2. You are selling a home in unincorporated Gilpin County with an OWTS (septic system) that was permitted and installed 5 years or less from the date of sale? No.
  3. You are selling vacant land? No. 
  4. You are selling vacant land with an installed OWTS but it is not connected to a permitted home or commercial structure and not operational? No. 
  5. You are selling vacant land with a permitted but unfinished/unconnected/non-operational OWTS? No. 
  6. You are selling a property with a permitted but unfinished home or commercial structure that is connected to a permitted but non-operational OWTS? No.
  7. You are selling a home or property with limited use structures such as seasonal cabin or home that is not connected to a permitted OWTS? Yes.
  8. You are selling a home that is connected to a sealed vault type OWTS? Yes. 

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. Use permits are valid for 6 months and must be obtained prior to the transaction date of the transfer of property subject to the use permit requirement. Active and unexpired use permits can be easily extended as long as you request the extension prior to expiration of the permit.
