A composting toilet does not replace an approved Saguache County OWTS

Off-grid living is a real draw on Saguache County’s many rural parcels, so composting toilets come up constantly in property conversations. There is a firm limit worth knowing up front. Alternative systems, including composting or incinerating toilets, are not allowed on their own unless an approved onsite wastewater treatment system, an OWTS, is installed first.

This catches people looking at cabins, camps, tiny homes, or land advertised as “ready for off-grid living.” A composting toilet sounds simple and self-contained, and in daily use it can be. But it does not stand in for the approved OWTS the county treats as the baseline for legal wastewater handling.

The rule traces to a plain requirement: to live and stay on the property, you need a county-approved septic system. Colorado’s Regulation 43 sets the state framework those approvals follow, so this is not a local quirk but the way onsite wastewater is handled statewide.

So before you buy or build around an alternative-toilet plan, get the wastewater picture from Saguache County Land Use. Ask what approved OWTS already exists on the parcel, what records sit on file, and what would have to happen before anyone can legally live there. The answer shapes whether that “off-grid ready” listing is move-in ready or a septic project waiting to start.
