Off-Grid Living in Kit Carson County, Colorado

I spent weeks searching for Kit Carson County off-grid regulations and found almost nothing published online - no zoning code, no building permit guidelines specific to off-grid structures, no health department fact sheets on septic timelines or alternative systems, and no county ordinances addressing greywater, rainwater, or utility disconnection. This absence is itself important information. It tells me that Kit Carson County either has no formal off-grid regulatory framework, or it has one that simply isn't documented in publicly accessible places. That gap creates real uncertainty for anyone planning to buy and build off-grid here. But it also means the county is unlikely to be aggressively policing off-grid infrastructure. What matters is understanding where county authority begins and ends, and where Colorado state law takes over.

Zoning: Unclear and Likely Minimal

Colorado state law gives every county the right to adopt zoning, but does not require it. Some rural Colorado counties have robust zoning codes; others have essentially none. Kit Carson County appears to fall into the latter camp. I found no published zoning code, no zoning map, and no evidence of active zoning enforcement in the county's online records. That does not mean zoning is impossible here - it means I cannot confirm what, if anything, the county enforces.

What this means for you: If the county does not enforce zoning, you have broad freedom to use your land as you wish (within state law). If it does, you need to know the rules before you buy. My honest advice: call the Kit Carson County Planning Office and ask directly: "Do you have an active zoning code? If yes, what zone am I in, and what uses does it permit?" Be specific. Ask whether off-grid dwellings, accessory structures, or agricultural uses have any restrictions. Write down the answer and the date you called. If the office says there is no zoning, ask for that in writing or via email.

Colorado state law also imposes a 35-acre subdivision threshold: you cannot split a parcel into smaller than 35 acres without county approval and platting. This rule applies statewide, including in Kit Carson County. If you are buying raw land here intending to keep it whole or to subdivide it later, confirm the current acreage and any easements or prior liens that might affect future division.

Dwelling: Unclear What "Permanent" Means Locally

Colorado state law recognizes tiny homes (under 400 square feet) as legal residential structures, but tiny houses on wheels are classified as RVs and cannot be legally permanent residences under state law. However, the state also allows counties to adopt their own rules. I found no Kit Carson County ordinance defining what counts as a permanent dwelling or restricting tiny homes.

What this means for you: If you plan to live in a conventional stick-built cabin or house, you are likely fine. If you plan to live in a THOW or a non-traditional structure, you must confirm with the Kit Carson County Planning Office whether that is permitted year-round. Ask: "Can I live full-time in a tiny house on wheels?" "What structures are permitted as permanent dwellings?" "Do I need a building permit for a dwelling?" Get the answer in writing if possible.

Standard Colorado baseline: any occupied dwelling will probably require some form of inspection and permit, whether zoning is enforced or not. The county health department is usually involved because a dwelling must have an approved waste system (septic, composting toilet, etc.).

Building Permits: No Threshold Found

I found no Kit Carson County documents specifying which structures require building permits or what code applies. Colorado state law allows each county to set its own threshold - some counties require permits for any structure over a certain square footage or cost, others have minimal permitting. The Colorado Uniform Building Code is the statewide baseline, but counties can adopt, modify, or ignore it.

What this means for you: Do not assume you can build a shed, barn, or cabin without a permit. Do not assume you can proceed without inspection. Call the Kit Carson County Building Department (may be housed with the Planning Office or the county assessor) and ask: - "What structures require building permits?" - "What is your dollar threshold or square footage threshold?" - "What building code do you enforce?" (reference the state code, local amendments, or neither) - "How long does a typical off-grid cabin or structure permit take?"

Write down the answers. If the county has no building department or cannot answer clearly, email your question and keep the response. This document will be useful if you ever need to explain why you built what you did.

Note: After July 1, 2026, Colorado counties that update their building codes must adopt the state's Model Low Energy and Carbon Code, which includes energy efficiency and emissions standards. If Kit Carson County has not updated its code by then, it can keep its existing rules. Ask the building department whether they plan to update by 2026.

Septic Systems: Permitted by County Under State Rule

This is the one area where I found clear authority: Colorado Regulation 43 (Department of Public Health and Environment) sets minimum standards for septic systems, and the Kit Carson County Health Department administers permits. Systems handling up to 2,000 gallons per day are permitted by the county; larger systems require state approval.

What this means for you: You will need a septic permit from the Kit Carson County Health Department. To get one, you will likely need: - A site plan showing the location of the dwelling, septic tank, drain field, and any wells - A soil percolation test (perc test) to determine soil suitability - A design plan for the septic system - An inspection once the system is installed

I did not find Kit Carson County's specific approval timeline or current processing standards online. Call the health department and ask: - "What is the typical timeline from application to permit?" - "What do you require for a perc test?" (Some counties require a licensed engineer; others allow a licensed soil evaluator or contractor.) - "Will you approve a low-flow or alternative septic system?" (Aerobic systems, sand filters, recirculating media filters.) - "Are composting toilets or vault toilets an option here?"

Composting toilets: Colorado state law limits composting toilets to sites where a conventional septic system cannot be installed (e.g., high water table, unsuitable soil). Any approved composting toilet must be NSF certified or equivalent. If you think your site might not support septic, ask the health department whether composting is an option before you buy.

Greywater Reuse: Legally Permitted in Colorado, But Not Confirmed Locally

Colorado state law (Regulation 86) allows greywater reuse - wastewater from sinks, showers, and washers - to be recycled for irrigation or toilet flushing, as long as the county adopts a local program that meets or exceeds state standards. I found no evidence that Kit Carson County has adopted such a program.

What this means for you: In the absence of a local greywater program, greywater is treated as sewage in Colorado and must be discharged through an approved septic system. You cannot legally route greywater to a separate system, tank, or leach field without county authorization.

However, local adoption of greywater is not difficult, and some Colorado counties have done it. Call the Kit Carson County Planning Office and ask: "Has Kit Carson County adopted a greywater reuse ordinance or resolution?" If yes, ask for a copy. If no, ask whether the county is considering it, or whether you could petition for it. (A 2-3 home project might be enough to trigger county interest, especially in a rural county where water conservation is valued.)

Until then, plan your off-grid water use around conventional septic: use a septic-safe toilet, route all wastewater through the tank, and use a conventional drain field. If greywater reuse becomes important to you, contact the county planning office to see if there is any path to local authorization.

Rainwater Harvesting: Legally Limited

Colorado's "Doctrine of Prior Appropriation" strictly limits rainwater harvesting. The state is a prior appropriation state, meaning water rights are allocated based on first-use, and "new" uses - like rainwater collection - can be restricted to avoid depleting downstream water supplies.

Current law allows most residential properties to collect no more than 110 gallons total across two rain barrels. Properties with an exempt residential well (35+ acres) have broader but still limited rights to use captured rainwater on-site for livestock and limited irrigation.

What this means for you: If you are on a 35-acre parcel with an exempt well, confirm with the Colorado Division of Water Resources whether your well permit includes rainwater use, and if so, what the limits are. If you are on a smaller parcel or without a well, assume you can collect 110 gallons (two rain barrels) without a permit. More than that requires a separate water right, which is expensive and time-consuming to obtain in Colorado.

For off-grid living, rainwater harvesting is a useful supplement (a roof can fill two rain barrels during a monsoon), but not a primary water source. Plan your off-grid water system around a well or hauled water, not rainwater alone.

Wells: Permit Required from the State

All wells in Colorado - including domestic wells - require a permit from the Colorado Division of Water Resources (DWR). There is no such thing as an unpermitted well, even on private land.

Lots of 35 acres or more typically qualify for an "exempt domestic well," which allows limited irrigation and livestock use without a separate appropriation. Smaller lots usually qualify only for a household well, which restricts water strictly to indoor residential use.

What this means for you: Before you buy off-grid land in Kit Carson County, contact the Division of Water Resources (not the county) and ask: - "Is my parcel eligible for an exempt domestic well?" - "What are the current well permit processing times?" - "Are there any active water disputes or restrictions in this area?" (Some basins in Colorado have been closed to new appropriations.)

If you are buying a parcel with an existing well, verify that the well is permitted and that the permit is in your name or that you can legally transfer it. An unpermitted well is a liability and may be ordered shut down.

Kit Carson County does not administer well permits; the state does. But the county health department may have records of existing wells on the property. Ask to see them when you apply for septic.

Utilities: No Mandate to Connect

Colorado has no state law requiring connection to the electric grid, municipal water, or any other utility. Solar, wind, and hauled water are legally viable in rural areas, including Kit Carson County.

What this means for you: You can legally build off-grid solar and wind here, subject to any county restrictions (which I found no evidence of). You can haul water, subject to well permit limits. You do not have to connect to a power company or water utility.

However, any occupied dwelling will need an approved waste system (septic, composting toilet, vault). You cannot simply discharge sewage on the ground or into an unapproved system. The county health department will require proof of an approved system before it signs off on occupancy.

Also check whether there are any HOA rules or deed restrictions on your specific parcel that might limit solar placement, wind turbines, or water tanks. These private restrictions can override your legal right to build off-grid.

Practical Sequence: What to Do Before You Buy or Build

1. Call the Kit Carson County Planning Office. Ask about zoning, building permits, and dwelling rules. Write down the answers. 2. Call the Kit Carson County Health Department. Ask about septic permits, timelines, alternative systems, and greywater. 3. Call the Colorado Division of Water Resources. Confirm your parcel's well eligibility and current water restrictions. 4. Get a perc test done (or know where to get one). If your soil is poor, septic may not work, and composting becomes your fallback. 5. Buy the land only after you have confirmed that you can legally build and occupy what you plan. 6. Apply for permits (septic, building, well) in the order the county recommends, typically septic first (because it affects dwelling placement), then building.

This sequence takes time but prevents costly mistakes - such as buying a parcel that cannot legally support a dwelling, or building a structure that fails inspection.

Honest Assessment

Kit Carson County is lightly regulated online and appears to have minimal zoning enforcement. That is often good news for off-grid buyers. But the lack of published rules also means there are gaps in what I can confirm. The county's actual enforcement posture, septic timelines, and any unwritten local standards are unknown from publicly available sources. You will have to call and ask. That is not ideal, but it is honest. And once you have those phone conversations, you will know more than I do, and more than anyone buying land in Kit Carson County without doing the work.
