Off-Grid Living in Logan County, Colorado

I've spent time mapping the rules that actually govern off-grid development in Logan County, and what I've found is a system where authority is split across the county planning office, the state building code enforcement structure, and Colorado's water and waste regulators. The good news: off-grid living is legally possible here. The hard part: understanding which office controls what, and in what sequence.

Zoning: Your Property Must Fit Its District

Logan County enforces countywide zoning regulations, updated in 2019. That means every parcel in unincorporated Logan County has a zoning classification - agricultural, residential, commercial, industrial, or some variant - and your off-grid plans have to fit that district. I could not locate specific subdivision lot-size minimums or small-parcel restrictions in the county materials I accessed, and that's an important gap to fill before you commit to a property.

What this means for you: Call the Logan County Planning & Zoning Department (they oversee all building and zoning matters) with your parcel's legal description or address and ask three things: What is your zoning district? What uses are permitted in that district? Are there minimum lot sizes or density limits for your intended use? The county's zoning regulations are publicly available online (updated 2019), but interpreting them for your specific parcel is worth doing with staff.

Colorado state law sets a 35-acre threshold for subdivision triggers in unincorporated areas, meaning parcels under 35 acres face stricter platting and improvement requirements. Logan County does not appear to impose its own lower threshold, but that doesn't mean your smaller parcel has no restrictions - confirm lot size and permitted use directly.

Dwelling Types: State Baseline, County Gatekeeping

Colorado recognizes tiny homes (under 400 sq ft) in state code, and there is no statewide prohibition on dwelling size in rural areas. However, I found no Logan County-specific rules on tiny homes, RV dwelling, or alternative structures. Your zoning district will ultimately dictate what kind of dwelling the county will permit.

What this means for you: If you are considering a non-conventional structure - a tiny home on a foundation, a converted outbuilding, or (less likely) a permanent RV installation - ask the Planning & Zoning Department whether your zoning district explicitly permits single-family dwellings, and whether there are secondary structure or ADU (accessory dwelling unit) rules that might apply. Tiny Homes on Wheels (THOWs) are treated as RVs under Colorado state law and cannot typically be permanent residences without a county variance or specific local allowance. Logan County's stance on this is unconfirmed, so don't assume it's allowed.

Standard site-built homes on a foundation are straightforward. Alternative dwellings require explicit approval.

Building Permits and Code Enforcement: County Issues, State Inspects

This is where the administrative split becomes real. Logan County requires a building permit for any construction, reconstruction, alteration, remodeling, or change of use on all dwellings, buildings, utilities, towers, and structures in unincorporated county. The county enforces the 2006 International Building Code, Residential Code, Mechanical Code, Energy Conservation Code, and Fuel and Gas Code.

But here's the twist: electrical and plumbing inspections are performed by the State of Colorado, not the county. This means you pull your permit from Logan County, the county inspector approves framing and general compliance, but then the state sends an electrical and plumbing inspector - they're separate coordinations.

What this means for you: 1. Contact Logan County Planning & Zoning to confirm that your project requires a building permit. Even utility infrastructure (solar arrays, water storage tanks, generator installations) may trigger the permit requirement - confirm scope before you order materials. 2. Submit your plans and pull the permit. The county will tell you the fee and timeline. 3. Schedule county inspections as you build (foundation, framing, etc.). 4. Separately, coordinate with the State of Colorado for electrical and plumbing inspections. The county can direct you to the state inspector contact or online system.

Because the county enforces 2006 codes (not the newer 2024 versions), your design flexibility may be slightly greater than in counties that have updated to current codes. However, this is not a loophole - the codes still apply, and inspectors will enforce them.

Septic Systems: Local Public Health Department Permits

On-site wastewater systems handling fewer than 2,000 gallons per day are permitted and overseen by the local public health agency, which enforces Colorado Regulation 43 (the state baseline for septic design, soil conditions, setbacks, and operation). I could not confirm Logan County's specific health department application process, fee structure, or any additional local requirements beyond the state rule.

Colorado Regulation 43 requires septic system design to account for soil percolation, groundwater depth, and distance from wells and surface water. Most systems need a professional septic designer and soil testing. Composting toilets are an option but only where a conventional septic system "cannot be installed" - which is narrowly defined and requires certification by an NSF-equivalent unit.

What this means for you: 1. Before buying: Have the property soil-tested for percolation if septic is your path. A failed perc test makes on-site septic infeasible and could be a deal-breaker. 2. Before permitting: Contact Logan County Public Health Department (or ask Planning & Zoning to direct you) and ask: How do I apply for a septic permit? Do I need a designer? What's the timeline and cost? What soils or distances disqualify a system? 3. Sequencing: Septic permitting usually happens before building permits, because the county wants to know your waste system is viable before approving the dwelling. 4. Composting toilets: If soil conditions are genuinely unsuitable for septic, ask about alternative systems - but expect this to be a rare approval and to require documentation that conventional septic won't work.

Greywater Reuse: Unconfirmed Locally, Regulated by State

Colorado state law authorizes greywater reuse (water from sinks, showers, and washing machines reused for irrigation), but it is locally administered. Counties must adopt a local greywater program that meets or exceeds state standards. I found no evidence that Logan County has published a local greywater ordinance or program, which means greywater may be subject to default state rules or may be treated as sewage requiring conventional disposal.

This is a real gap in my research, and it is worth confirming.

What this means for you: 1. Contact Logan County Public Health Department and ask explicitly: "Does Logan County have a local greywater reuse program?" If yes, get the details. If no, ask what the default requirement is. 2. If greywater is permitted, you'll likely need a design meeting state irrigation standards and distance/filtration requirements. 3. If greywater is not permitted locally, you must dispose of it as blackwater - meaning it goes to your septic system, which affects sizing and treatment.

The safest assumption right now is that greywater is restricted, and you should design your septic system accordingly.

Rainwater Harvesting: State-Capped at 110 Gallons

Colorado state law strictly limits rainwater harvesting due to the Doctrine of Prior Appropriation - essentially, most water belongs to someone downstream with a senior water right. Most households may collect no more than 110 gallons total across two rain barrels.

I found no additional Logan County restrictions, meaning the state cap applies directly here.

What this means for you: If you want to harvest rainwater for landscape irrigation or toilet flushing, you're legally limited to two 55-gallon barrels (or equivalent small cistern) on your property. That's not much, but it's legal and requires no permit. If your property is served by an exempt domestic well (which some 35+ acre parcels qualify for), you may have broader rainwater rights - this is worth confirming with the Colorado Division of Water Resources when you apply for your well permit.

Private Wells: State Permits and Water Rights

All wells in Colorado require a permit from the State Engineer through the Colorado Division of Water Resources. This is a critical step, and it is entirely separate from county building permits.

Lots of 35 acres or more typically qualify for an exempt domestic well, which allows a household limited quantities of water (usually around 15 gallons per person per day) plus modest livestock watering and irrigation. Smaller lots or households-only wells restrict water strictly to indoor use and may be more difficult to permit.

I found no Logan County-specific well or water rights rules beyond the state baseline.

What this means for you: 1. Before finalizing a property purchase: Contact the Colorado Division of Water Resources and ask whether your specific parcel qualifies for an exempt well. Provide the legal description and ask about water availability and any existing senior rights that might limit your use. 2. Well permit process: This is not a county permit. You file directly with the state Division of Water Resources. Lead times vary; start early. 3. Groundwater availability: Logan County is in an area with variable groundwater depth. Some properties have shallow, productive aquifers; others require deep drilling or have marginal water. A hydrogeologic assessment or existing well data on nearby properties will help you understand feasibility. 4. Water rights law: If your property is in an area with adjudicated water rights or within a groundwater basin with restrictions, your well permit may be denied or severely limited. This is a showstopper scenario - confirm it before you buy.

Contact the Division of Water Resources as soon as you have a property under consideration.

Off-Grid Utilities and Infrastructure

Colorado state law does not require connection to the electric grid or municipal water supplies. This means solar, wind, and hauled water are legally viable options. However, disconnection from sewage systems is practically prohibited in most areas - any permitted structure typically must have an approved waste system (septic or otherwise).

Logan County requires building permits for any utility installation or structure, including solar arrays, wind turbines, water storage tanks, and generator installations.

What this means for you: 1. Solar and wind: Legal and permit-friendly. Confirm with the county that your planned system size and placement require a permit and what the process is. 2. Water storage: Confirm that cisterns, tanks, and rainwater systems require permits. They likely do. 3. Generator and backup power: Likely permitting required, especially if it's a large installation. 4. Propane and heating fuel: Permitted and code-regulated. Confirm tank placement, venting, and inspection requirements with the county.

Building code compliance and county inspection apply to all of these, so work with the Planning & Zoning Department on scope upfront.

The Realistic Sequencing for an Off-Grid Build in Logan County

Here's the order that makes sense:

1. Confirm zoning and lot suitability with Planning & Zoning (zoning district, permitted uses, lot size rules). 2. Contact Division of Water Resources to verify well permit feasibility and water rights availability for your specific property. 3. Soil test for septic if that's your waste strategy (or confirm alternative waste systems with public health). 4. Contact Public Health Department for septic permitting process, fees, and designer requirements. 5. Design and permit septic through public health (usually before building permit). 6. Pull building permit from county for dwelling and any associated structures, with complete architectural and utility plans. 7. Schedule county inspections (foundation, framing, electrical/plumbing rough-in, final). 8. Coordinate state electrical and plumbing inspections through the state inspector. 9. File for well permit with Division of Water Resources in parallel with building (not sequential). 10. Construct and finalize inspections.

Septic and wells move slowly; start those conversations first.

Honest Gaps and How to Fill Them

I could not confirm: - Logan County's specific public health department requirements or application process for septic systems - Whether Logan County has adopted a local greywater reuse program - Specific lot-size minimums or density requirements in your zoning district - Logan County's stance on tiny homes, accessory dwellings, or alternative structures

For each of these, call the Planning & Zoning Department first - they coordinate with public health and can usually direct you to the right office. If not, ask for the public health director directly.

The bottom line is that Logan County is administrable for off-grid living, but only if you confirm the rules specific to your parcel early, work sequentially, and coordinate across county building authority, state inspector resources, and state water/waste regulators. Don't assume; ask.
