Off-Grid Living in Conejos County, Colorado

Conejos County, Colorado enforces its own countywide zoning and requires building/septic permits even though it hasn't adopted state building codes, while wells and greywater fall under separate state rules. Off-grid power and water systems are legal, but nearly every structure and system still needs a permit from the county Land Use Office or the state.

Is it legal to live off-grid in Conejos County, Colorado?

There is no outright ban on living off-grid in Conejos County, Colorado - it is legal but regulated. Zoning and land use are restricted, putting a cabin, tiny home, or RV on raw land is set locally and vary by area, and building permits are set locally and vary by area. Plan around septic/wastewater (restricted) and disconnecting from utilities (set locally and vary by area). Because these rules are set locally, confirm the specifics with Conejos County before you buy land or build.

Read this before you act on anything below. This is my researched starting point for Conejos County, not legal advice and not a guarantee. Rules change, and the deciding facts on any specific parcel (setbacks, perc results, overlay districts, deed restrictions, road frontage) live at the county or town office, not in any database. Before you buy land or build, confirm the current rules directly with the local zoning and health offices - the sources on this page tell you exactly who to call.

Conejos County at a glance

Zoning & raw-land occupancy
RestrictedConejos County administers its own 2005 Land Use Code countywide with Agricultural, Residential, Commercial, and Industrial districts; the Land Use Office states permits are required and many uses need a special/conditional use permit. source
Dwellings, tiny homes & RVs
Varies locallyResidential/Agricultural zoning generally allows one single-family dwelling per parcel; industrial-zoned land does not allow residential structures at all. Tiny-home-on-wheels or RV occupancy rules were not confirmed, so check with the Land Use Office. source
Building permits & codes
Varies locallyConejos County has not adopted the state building codes ahead of a statewide 2026 deadline, but a county building permit is still mandatory and the permit packet references codes like the 2018 International Energy Conservation Code; building without an approved permit is treated as a violation. source
Septic & composting toilets
RestrictedThe county Land Use Office administers the OWTS (septic) program under Colorado Regulation 43 and the county Board of Health; a site and soil evaluation is mandatory and installing without a permit doubles fees. Composting toilet specifics were not confirmed, so verify directly with Land Use. source
Greywater reuse
Unclear - verifyColorado law only permits greywater reuse where a county has adopted a local program and notified the state Water Quality Control Division; no evidence of such adoption in Conejos County was found, so confirm current status with the Land Use Office or Board of Health.
Rainwater harvesting
RestrictedNo Conejos-specific ordinance was found; the state's general residential rain barrel allowance under Colorado's prior appropriation water law appears to be the operative rule here, not confirmed to be modified locally.
Private wells & water rights
RestrictedPrivate wells are permitted and regulated entirely by the Colorado Division of Water Resources (Office of the State Engineer), not by Conejos County; the county may require proof of water supply during building review. source
Living disconnected from utilities
Varies locallyNo Conejos County ordinance requires grid-tie or municipal water hookup, so off-grid solar, wind, and hauled or well water are legal, but the dwelling, septic system, and well still require their own permits. source

I've spent a fair amount of time digging through county documents for this brief, and Conejos County, Colorado is a bit of an outlier in the state. Here's what I found for unincorporated Conejos County (the five towns, Antonito, La Jara, Manassa, Romeo, and Sanford, run their own separate rules, so this doesn't apply inside town limits).

Zoning. The county's Land Use Office says it plainly: Conejos County is zoned, and permits are required. The county runs its own 2005 Land Use Code with Agricultural, Residential, Commercial, and Industrial districts, plus setbacks and lot coverage rules. Beyond by-right uses, you'll often need a special or conditional use permit. This isn't a county where you can just buy raw land and do whatever you want.

Dwellings. Residential/Agricultural zoning generally allows one single-family dwelling per parcel. Industrial-zoned land doesn't allow residential structures at all. The county also distinguishes pre-1976 "mobile homes" from post-1976 HUD-standard "manufactured homes," which can matter for placement rules. I couldn't confirm specific rules on tiny homes on wheels or long-term RV living, so that's a call to make directly to Land Use.

Building permits and codes. Here's the interesting part: Conejos is one of the Colorado counties that hasn't adopted the statewide building codes, ahead of a 2026 state deadline that will change that for many counties. But "no adopted code" doesn't mean "no permit." The county's own permit packet is explicit that building without an approved permit is a violation, and it references the 2018 International Energy Conservation Code for at least some elements. Get a permit from Land Use before you build anything.

Septic and composting toilets. The county Land Use Office runs the OWTS (onsite wastewater) program under the state's Regulation 43 and the county Board of Health. A site and soil evaluation is required before you can even design a system, and installing without a permit doubles your fees. Composting toilets aren't separately addressed in what I found, so I'd assume they fall under the same OWTS review until Land Use tells you otherwise.

Greywater. Colorado only allows greywater reuse where a county has affirmatively adopted a local program and notified the state Water Quality Control Division. I found no evidence Conejos County has done this, so I'm treating greywater reuse here as not authorized until you confirm otherwise with the Land Use Office.

Rainwater. No county-specific rule turned up. Colorado's general residential rain barrel allowance (a modest, capped collection amount under the state's prior appropriation water law) appears to be the operative rule here.

Wells. Wells are entirely a state matter. The Colorado Division of Water Resources, not the county, issues well permits and administers exempt-well rules. The county may ask for proof of water supply during building review, but the well permit itself comes from the state.

Off-grid utilities. No ordinance found requiring you to hook up to the grid or municipal water. Solar, wind, hauled water, wells, all legal, but the structures and systems around them (dwelling, septic, well) still need their own permits.

Bottom line: Conejos gives you more off-grid freedom on the code side than most Colorado counties, but it still wants you to come through its Land Use Office for permits at nearly every step.

Planning a build in Conejos County

The rules above decide what you may build. The numbers below decide what you will have to build, and they come from this place rather than from a national average.

Solar: size for the worst month, not the average

Conejos County averages 5.9 peak sun hours a day across the year, but its worst month averages 4.6. That is a drop of about 23 percent. An array sized on the annual figure will therefore come up short in the worst month by roughly that much, in the season when lights, pumps, and heating fans all run hardest.

Put another way, meeting the same daily load in the worst month here takes about 1.3 times the array that the annual average implies, or a generator and the fuel budget to run it. Neither is wrong; what is wrong is discovering the gap in the first winter. The solar calculator runs this arithmetic against your own load list, and lesson four covers building that list before buying panels.

Heat: 8,321 heating degree days

That is a severe heating season, where the building envelope matters more than any appliance you can buy. Heating demand at this level dwarfs everything electrical in the house, which is why almost nobody here heats with electricity from a battery bank.

As a rough order of magnitude, a small, reasonably insulated cabin heated mainly with wood in a climate like this tends to burn in the region of 6.9 cords a season, with the real figure swinging widely on insulation, house size, and how you burn. Treat that as a bracket for planning your woodshed rather than a promise, split and stack a season ahead, and check with a moisture meter before burning. The firewood calculator and heat-loss calculator narrow it down from your own building.

Water: what the roof would actually catch

Conejos County receives about 23.5 inches of precipitation a year. A 1,000 square foot roof here would shed on the order of 12,455 gallons a year at a realistic 85 percent collection efficiency, before any losses to first-flush diversion, evaporation, or overflow in a heavy storm.

The annual total is the easy part. What sizes a cistern is the longest dry stretch, because catchment is seasonal almost everywhere and a tank that covers the average year can still run empty in August. Check the local rules too: rainwater harvesting is regulated in some states even where it is broadly allowed. The rainwater calculator works from your own roof and rainfall pattern, and lesson three covers why water is chosen before power.

Snow: 97 inches in an average year

At this level, snow is a design input rather than a nuisance. It sets the roof load your structure has to carry, it decides where a metal roof may safely shed and therefore where doors, propane tanks, and walkways must not be, and it buries a ground-mounted array at exactly the time of year the array matters most. It also makes the driveway a system: how it is graded, where the snow is pushed, and who clears it when you cannot.

Distance is part of the plan

Measured straight line from the center of Conejos County: the nearest fire station is about 8.7 miles away (Chama Fire Department), the nearest hospital is about 33.6 miles away (Conejos County Hospital), the nearest supermarket is about 10.1 miles away (Lowe's Market). Road miles will be longer, and in winter longer again.

The fire distance is worth noting before you buy rather than at renewal: insurers commonly rate rural property partly on how far it is from a responding station and from a water source, and some decline off-grid or owner-built structures outright. Ask an agent who writes rural policies what they would need to see, while the answer can still change what you build. Lesson eleven covers the insurance and financing side.

The hospital distance sets what your first aid kit and your medical plan have to cover in the gap, and it is the number to think about before anyone in the household depends on refrigerated medication or mains-powered equipment.

Confirming this for your own parcel

On this page 4 of the eight topics are recorded as unclear or as varying within Conejos County: what counts as a dwelling, building permits and codes, greywater, mandatory utility connection. Those are the calls to make first, because they are the ones where a general answer cannot be trusted for a specific parcel. Ask for the answer in writing where the office will give it, and note the name and the date where it will not.

Where a topic is recorded as settled here (zoning, septic and sewage, rainwater harvesting, wells and water rights), the source is cited further down this page. Sources go stale, ordinances get amended, and this site logs corrections publicly rather than editing them away, so if you find something here that no longer matches the county, the corrections page is how to say so.

Before any of those calls, walk the parcel with the land walk checklist and take the questions for the county with you. The parcel check pulls flood, wetland, slope, and access data for a specific parcel and shows its sources, which is a good way to arrive at the office with the questions already framed. Lesson two is the wider version of this list.

FAQ

Common questions about off-grid living in Conejos County

Can I live off-grid legally in unincorporated Conejos County?

Generally yes, there's no ordinance forcing you onto the grid or municipal water, but you still need a county permit for the dwelling, an OWTS permit for wastewater, and a state permit for any well.

Does Conejos County have building codes?

Not fully adopted ones, unlike most Colorado counties, but a building permit is still required by the county's own Land Use Office and building without one is a violation.

Is greywater reuse allowed?

Only if the county has adopted a local greywater program and notified the state, and no evidence of that was found for Conejos County, so treat it as not authorized until you confirm with Land Use.

Who issues well permits here?

The Colorado Division of Water Resources (state), not the county. The county may ask for proof of water supply during building review.

Are tiny homes or RVs allowed as full-time residences?

Not confirmed in the county's official documents; contact the Land Use Office directly since zoning rules distinguish mobile, manufactured, and site-built homes.
