New La Plata County Septic Rules in 2026: What Sellers Need to Know (Video)
La Plata County adopted new on-site wastewater treatment system regulations that took effect March 2, 2026. If you’re selling a home on septic, here’s what changed and what to do before you list.
What changed
The County Board of Health adopted the updated regulations in January 2026, effective March 2, 2026. Colorado Regulation 43 was adopted by reference and took effect in the county on the same date. The former Transfer of Title program is now the Continued Use Permit program.
What sellers need to know
- Most properties served by a septic system still have to be inspected before they can sell.
- Sellers still need a document from Public Health before closing.
- Existing systems that are functioning properly do not have to be upgraded to the new standards just because the property is being sold.
- The inspection has to be performed by a third-party NAWT-certified inspector, not a general home inspector.
- The updated design and siting standards apply to new installations, replacements and significant repairs.

It also covers what happens if a system fails or isn’t properly permitted, who is exempt from the Continued Use Permit requirement, and what every seller should do before listing.
