Off-Grid Living in Garfield County, Colorado

When I began researching off-grid feasibility in Garfield County, I quickly learned that this county sits at the intersection of two regulatory realities: strong local control over land use and building, paired with Colorado state law's tight grip on water rights and waste systems. The good news is that off-grid living is possible here. The hard part is understanding which rules are actually yours to navigate and which ones belong to the state—and knowing exactly what to confirm before you commit to land purchase.

Zoning: Know Your Zone Before You Buy

Garfield County maintains its own zoning authority, and that means the first thing you need to establish is whether your target parcel is even zoned for residential use at all. The county uses RS (residential) zones with minimum lot-size requirements, but I was unable to locate a complete, current zoning code document online or confirm whether unzoned areas exist outside the main jurisdictional districts. This matters enormously for off-grid planning.

Here's why: minimum lot sizes directly determine septic feasibility. Colorado state septic standards require minimum distances between wells, property lines, and water courses, and a 1-acre parcel in a 5-acre minimum zone won't work—period. Additionally, if your parcel sits in an unzoned area, the rules may be less prescriptive, but you'd need to confirm that with the county before assuming freedom.

What to do: Before making any offer or spending money on a survey or water rights check, call Garfield County Community Development at your earliest opportunity and ask three specific questions: (1) Is my parcel zoned or unzoned? (2) What is the minimum lot size for my zone? (3) Are there any overlay districts or special restrictions on my property? Get the answers in writing if possible. This step takes 20 minutes and can save you tens of thousands of dollars.

Dwelling Standards: Colorado Code, Locally Enforced

Colorado state law defines what counts as a dwelling, and Garfield County enforces that definition locally. Tiny homes under 400 square feet are recognized in state code, but I found no Garfield County–specific exemptions or special allowances. If you're planning a non-traditional structure—a tiny house, a cabin under a certain size, a modified structure—you'll need to confirm with Community Development that your design will pass local interpretation of state standards.

The practical implication: you cannot rely on word-of-mouth from other counties or online forums about what "might work." What matters is Garfield County's staff interpretation of the state code as it applies to *your* structure. This is a conversation worth having during the zoning-confirmation step above.

Building Codes and Permits: No Shortcuts Here

This is where Garfield County draws a firm line. The county has adopted the 2015 International Residential Code and International Building Code, effective July 1, 2016, and operates under the 2018 International Energy Conservation Code. All cabins, tiny homes, and off-grid structures must comply. There are no exemptions for park trailers or alternative dwelling types under ANSI 119.5.

What this means in practice: every structure you build will require a building permit, and that permit application will trigger a compliance review against both the adopted codes and the county's Land Use Code. You cannot build incrementally or informally. You need an engineered design, a permit, and inspections at framing, electrical, mechanical, and final stages. For an off-grid cabin, this typically means:

• A set of plans that meet IRC energy and structural standards
• A registered professional engineer or architect for anything more than a very simple structure
• Electrical and mechanical permits in addition to the building permit
• On-site inspections by county staff

Budget for professional design help. It's not optional. And because energy code compliance is mandated, you'll need to demonstrate how your off-grid power system meets the 2018 IECC standard—whether through solar specifications, insulation values, or both.

Septic and Wastewater: Two Permits, One Timeline

Colorado state law sets the baseline for Individual Sewage Disposal Systems (septic), and Garfield County administers it locally with no known variances. Here's what you must do:

1. Obtain an OWTS (On-Site Wastewater Treatment System) permit from Garfield County before you install anything. This is a separate permit from the building permit. 2. Submit an ISDS (Individual Sewage Disposal System) application alongside your building permit application. These are the same system; the names refer to different regulatory stages. 3. Comply with Colorado State Board of Health standards for system design, installation distance from wells (typically 50+ feet), and setbacks from property lines and water courses.

I found no county-specific allowances for composting toilets. Colorado law permits composting toilets only as an alternative to conventional septic systems when a conventional system cannot feasibly be installed—and even then, the unit must carry NSF or equivalent certification. Garfield County does not appear to have created an easier path for composting toilets, so treat conventional septic as your baseline plan.

For off-grid cabins, this also means: if your septic system includes a pump (which it will if gravity drainage isn't feasible), you'll need an electrical permit for the pump wiring, even if the rest of your cabin is solar-powered. Plan for professional septic design and installation. A site evaluation by a Colorado-licensed septic designer is typically your first step, not your last.

Water: Three Separate Systems, Three Separate Rules

This is where off-grid planning in Garfield County becomes genuinely complex, because Colorado state law—not county ordinance—controls what you can do with water.

Domestic Wells and Water Rights

Colorado requires a water rights permit from the State Engineer for any well, with one critical exception: exempt domestic wells. On parcels of 35 acres or larger, an exempt domestic well typically allows 15 acre-feet per year (roughly enough for household use plus limited livestock or irrigation). On smaller parcels, a well is restricted to household indoor use only—no outdoor watering, no livestock, no gardens beyond a very limited vegetable plot.

I found no Garfield County–specific well rules, which means state law is your entire framework. Before you buy land for an off-grid cabin, you must determine: (1) Does your parcel qualify for exempt-well status? (2) If not, are there existing water rights available? (3) How deep is groundwater in your area (deep wells cost substantially more)?

Contact the Colorado Division of Water Resources. They can tell you whether your parcel qualifies for an exempt well and what the likely well depth is in your area. This is a non-negotiable step before purchase.

Rainwater Harvesting

Colorado's Doctrine of Prior Appropriation is famous—or infamous—for restricting rainwater. Under current law (HB 16-1005), a household on a residential property may collect no more than 110 gallons total across two rain barrels. If your property is supplied by an exempt residential well, you have broader rights to use captured rainwater on-site, but the rules are still limited.

For off-grid living in Garfield County, this means rainwater is a supplement, not a primary water source. You can catch 110 gallons for a modest garden or emergency use, but you cannot size a rainwater cistern as your main household supply. Plan for a well or hauled water as your primary source.

Confirm the current rainwater rules with the Colorado Division of Water Resources before assuming you can expand your collection beyond the 110-gallon limit.

Greywater Reuse

Colorado state law authorizes greywater reuse (water from sinks, showers, and washing machines), but it must be locally administered. I found no Garfield County–specific greywater program, which means greywater currently must be treated as sewage in the county. Any greywater from your off-grid cabin will need to flow to your permitted septic system—you cannot divert it to irrigation or reuse it without a formal county program in place.

This is worth confirming directly with Garfield County Community Development: ask whether a local greywater program exists and whether your septic designer can specify a system that allows future retrofit for greywater reuse.

Utilities: Disconnection, Solar, and Local Rules

Colorado state law does not require you to connect to the electric grid or municipal water. Solar and wind are viable, and hauled water is legal. However, I found no Garfield County–specific utilities disconnect rules, which means you must confirm with your specific local utility provider whether they allow permanent grid disconnection and what that process entails.

For most rural Garfield County properties, this is straightforward: you can disconnect and go solar. But if your parcel sits in an area served by a specific electric cooperative or municipal utility, that provider may have rules about permanent disconnection or may require a nominal connection fee even if you don't use grid power. Call ahead.

For water, hauling is standard in rural Garfield County. For wastewater, you must have an approved septic system (you cannot disconnect sewage).

Practical Sequence: What to Do First

If you're serious about off-grid land in Garfield County, here is the realistic sequence:

1. Identify a specific parcel. Get a legal description and contact information. 2. Call Garfield County Community Development. Confirm zoning, minimum lot size, and any restrictions. Ask about the jurisdiction (county or municipal) and get contact info. 3. Contact the Colorado Division of Water Resources. Ask about exempt-well eligibility for your parcel and typical well depths in the area. 4. Hire a septic site evaluator. They will assess groundwater depth, soil, and feasibility. This costs $300–$800 and is essential. 5. Hire a surveyor if you don't have a recent survey. You need to confirm property lines before septic design. 6. Consult with a local engineer or architect. If you're building anything other than a very simple structure, get preliminary design feedback. This is not optional under Garfield County codes. 7. Confirm utility disconnection feasibility. Call your local electric provider and ask about permanent disconnection. 8. Only then pursue purchase. Don't buy until you know water, septic, and zoning are viable.

What Remains Uncertain

Despite my research, I could not confirm a complete, current Garfield County zoning code online or a full list of all districts and their minimum lot sizes. I also could not locate county–specific rules on accessory dwelling units, RVs, tiny homes on wheels, or alternative structures beyond the IRC/IBC baseline. For any of these, contact Community Development directly before proceeding.

Off-grid living in Garfield County is feasible, but it requires diligence at the county and state level. The county controls your building and septic framework; Colorado controls your water. Success means respecting both.
