The local rulesLas Animas County, CO
Zoning & raw-land occupancy
Varies locallyLas Animas County maintains countywide zoning districts, permitted/conditional/prohibited uses, accessory building rules, and mobile home park/campground regulations under its Land Use Regulations, administered by the County Planning Commission and Planning and Land Use Office. Inside incorporated towns like Trinidad, municipal zoning applies instead. source
Dwellings, tiny homes & RVs
Varies locallyThe county's Land Use Regulations cover mobile home parks, campgrounds, and accessory buildings, but specific rules on tiny houses on wheels, RV occupancy, or minimum dwelling size were not confirmed in available documents. Confirm directly with the Planning & Land Use Office. source
Building permits & codes
RestrictedThe county requires building permits and adopts the 2018 International Building Code family (IRC/IBC/IMC) plus the 2018 International Energy Conservation Code, with structural elements needing review or a wet stamp from a Colorado-registered engineer. A septic permit must be completed before a building permit is issued. source
Septic & composting toilets
RestrictedThe Las Animas-Huerfano Counties District Health Department permits and regulates septic/OWTS installation under state Regulation 43, requiring a permit application and licensed installers; composting toilet specifics are not confirmed separately. source
Greywater reuse
RestrictedGreywater use is governed by Colorado state rules under the Division of Water Resources, tied to the state's water rights system; no county-specific greywater ordinance for Las Animas County was confirmed, so the state framework applies by default. source
Rainwater harvesting
RestrictedState law allows rain barrel collection up to a combined 110 gallons without a permit for single-family or small multi-family residences, per Colorado statute; no Las Animas County-specific rainwater rule was found. source
Private wells & water rights
RestrictedLas Animas County's own building guidance directs residents to the Colorado Division of Water Resources for well permits, confirming there is no separate county well permitting layer, only the state process. source
Living disconnected from utilities
Varies locallyNo official Las Animas County or state source found imposing a mandatory grid or utility hookup requirement; county building focus is on code compliance, septic, and water permitting rather than utility connections. Confirm with the Building Department for specifics on off-grid power setups.
