Off Grid Living in Colorado: Laws, Land and Permits

I love the beautiful nature in Colorado and how adventurous many of the locals are.


There has also been a substantial off-grid living boom in the past decade, with many people aiming to live completely self-reliant, sustainable lives.

This surge has led to some friendly off-grid laws in Colorado.


Is Living Off-Grid Legal in Colorado?

In many places in Colorado, off-grid living is entirely legal.

However, that doesn’t mean you’ll be able to do whatever you want on your property.

Most counties have stringent zoning laws and building codes.  You’ll probably need a permit for everything from your toilet to wood stove and have to endure multiple inspections.  And, while you might be able to do everything legally, building an off-grid home in Colorado will be very expensive – especially if you want water rights.

Colorado Zoning Laws and Off-Grid Living

Zoning laws are created by local governments and determine what residents are allowed to do on their property. Compared to other states, most areas in Colorado have very detailed and restrictive zoning laws.

There used to be some rural counties in Colorado without zoning laws. However, these areas have started to create and enforce zoning laws.  For example, Delta County was considered one of Colorado’s best places to go off-grid because of its lack of zoning laws. But, starting in April 2021, the entire county is zoned.

Below are just some of the rules you can expect to find in Colorado zoning laws:

  • Permitted uses: There are many restrictions to what you can do on your land. Some types of agriculture are even prohibited or limited (especially livestock) on land zoned as Agriculture.
  • Minimum lot size: Many places have a minimum lot size of 20 or 35 acres for agriculture-zoned land.
  • Who can live there: Zoning laws often state that only family members can live on a property. Farmhands may be allowed on agricultural land, but they must be legally employed.  If you want multiple families to live on the same plot, you’ll need to find land zoned as “Residential Multi-Dwelling.”
  • Accessory buildings: There are severe restrictions on accessory buildings. You usually cannot have anyone living in an accessory dwelling unless it is a hired farmhand and their family members.  Even then, you will probably be required to get a permit.

Best Places in Colorado for Off-Grid Living

Below are some of the counties in Colorado with the most relaxed zoning laws.

  • Custer County: This rural county allows farming and ranching as a right on all land. They even allow green burials.  The main obstacle is that some zones require a minimum of 80 acres of land. There are still annoying permit requirements for virtually everything, though, and, as one resident said, “HOAs are crazy out here.” 
  • Montezuma County: Montezuma has very relaxed zoning rules, and most of the land is zoned for agricultural use, so there may be sizeable minimum lot requirements. They do not enforce building codes.
  • El Paso County: Outside of Colorado Springs, the zoning laws are relatively relaxed. There is even some forest land that is zoned to allow residential use.
  • Huerfano County: This county, which includes Walsenburg, has laws favorable to tiny homes and more relaxed building codes.
  • Rio Grande County: Farming is allowed by right even on residential-zoned lands. The minimum lot size required for wells and on-site sewage systems is lower than in other areas of Colorado.
  • Costilla County: Many people flocked to Costilla County to live off-grid because of the cheap land prices. The county has started cracking down and enforcing codes, but it is still one of the more relaxed places to live off-grid in Colorado.
  • Saguache County: This county still does not have any codes. Please let us know if that changes.
  • Las Animas County: The minimum lot size is smaller in this county. The zoning laws and building codes are slightly more relaxed too.

Land Covenants in Colorado

Another thing to be aware of when going off-grid in Colorado is land covenants.  Also called CC&Rs (covenants, conditions, and restrictions), these are written into the property deed.  Even if the local law says that something is allowed, the covenant takes precedence.  Counties don’t enforce covenants, but you could be taken to court for violating the rules.

While covenants are often found in subdivisions, many rural or forest Colorado properties have environmental covenants.  Ensure you check with the county clerk to see if there are any covenants on the property before you buy or build.

Colorado’s 35 Acre Law

You’ll probably have to buy at least 35 acres of land for an off-grid property in Colorado.  This is because of a 1972 law prohibiting landowners from splitting property into less than 35 acres: parcels less than 35 acres require subdivision approval in almost all counties.  Some counties have even higher acreage requirements.

Land on less than 35 acres is required to meet state laws regarding sewage, curbs, gutters, and other infrastructure.  This is why parcels of land less than 35 acres often cost as much as (or even more than) parcels of 35 acres or more: you are essentially paying for the existing infrastructure on that small parcel.

There are numerous benefits of buying 35 acres or more in Colorado, such as having more water rights or having livestock. Farmland in Colorado is already expensive, and the 35-acre rule means going off-grid can be very expensive.

Off-Grid Electricity in Colorado

Colorado gets a lot of sunshine, and solar power is very popular in the state.  You can expect solar or other off-grid electricity systems to be specifically addressed in your county’s building codes.  There are state incentives and rebates for installing solar panels.  Solar systems are exempt from property tax.

However, local building codes may make it illegal not to have any form of electrical lighting. For example, businesses may be required to have lighting for safety reasons.

Off-Grid Water in Colorado

Colorado is one of the strictest states in regard to water rights. Under the rule of prior appropriation, known as the Colorado Doctrine, all surface water and tributary groundwater in the state is a public resource. You must get a permit to use that water.  Getting water use permits can be very complicated and expensive and might even be impossible depending on your property’s size and location.

To make matters worse, a landowner must have water before being allowed to build on the land. You will likely need to pay a small fortune for property that already has water rights or thoroughly investigate your water options before buying any land.

For more, see the guide to water rights from the Colorado State Government.

Surface Water

Even if you have a stream, lake, or other surface water on your property, you don’t have the right to use it.  You first must apply for a water permit.  The application must include a plan for how you plan to use the water, how much water you will use, what “beneficial use” the water is for, and other details.

If your permit is approved, you use the water for the described purpose.  Once the water is used, it has been “appropriated” under the rule of prior appropriation.  The surface water rights can then be sold to third parties.  Or you can purchase those existing water rights from whoever owns them.

Read a detailed account of how to get surface water rights in Colorado.

Ground Water

You need a permit from the Colorado Department of Natural Resources to dig a well on your property.

If your property is less than 35 acres in size, you will only get a household use well permit.  This means the water can be used inside your home but not for outdoor uses like watering plants or livestock.

However, a loophole to this law is that you can garden indoors – such as starting an aquaponics garden.

Properties that are 35 acres or more can get a domestic well permit, which allows you to use water outdoors. However, there are limits on how much water you can pump per minute.

The groundwater laws are full of exceptions that might further prohibit you from getting a well, such as if your property is in a designated water basin or there is a “plan for augmentation.”

See this document from the Division of Water Resources for details on Colorado well water permits and rules.

Rainwater Harvesting

Rainwater harvesting in Colorado is legal. However, it is highly regulated.  Under House Bill 1005, residential homeowners can have two rain barrels with a combined capacity of 110 gallons.  The rainwater can only be collected from their roof and must be used on their property.  The water is only for outdoor purposes and cannot be used indoors or for potable water.

There is a useful loophole in the law, though: so long as it goes onto the ground, you can divert as much rainwater as you want.  That means you could rig a rainwater system that diverts water onto your garden.

Read more details about the law.

Greywater Recycling

As of 2015, Colorado Regulation 86 lays out the rules for greywater recycling in the state.  There are rules about how the water can be used (typically only outdoors) and gallons per day.  Under the law, water from bathroom and laundry room sinks, bathtubs, showers, and laundry machines can be recycled. Wastewater from toilets, urinals, kitchen sinks, dishwashers, and nonlaundry utility sinks cannot be recycled.

Sewage and Waste Removal

Colorado is one of the more progressive states regarding off-grid waste disposal.  The law actually mentions compost toilets and other alternative systems (which isn’t the case with many state laws), so there is no gray area.

However, while you will be legally allowed to have alternative waste systems, you’ll still most likely be required to have a septic system or hook up to the municipal sewer system.

Read Colorado’s on-site wastewater treatment laws.

Compost Toilets

Compost toilets are legal in Colorado so long as they are approved by the National Sanitation Foundation or an equivalent testing program.

The law states that,

residue from the unit shall be properly disposed of by acceptable solid waste practices.

You are not allowed to dispose of waste on the ground or in water. You’ll also need an approved system for treating wastewater from the composting toilet.  So, in most cases, you will also be required to have a septic system.

You’ll have to check with your local government to see what their specific rules are.


Outhouses are essentially illegal in Colorado.  They can only be used as a temporary method (no more than 7 days) and in very remote areas where “other approved sanitary means are unavailable.”

Other Off-Grid Laws in Colorado

  • Wood stoves: To prevent air pollution, Colorado strictly regulates which types of wood stoves can be used and in which circumstances. Read the rules here.
  • Tiny homes: In most cases, tiny homes on wheels will be considered an RV in Colorado. Local zoning laws usually make it illegal to live in an RV.  However, Colorado law is becoming more friendly to tiny homes, so long as those homes are on a permanent foundation and have approved wastewater systems.
  • Homeschooling: Colorado has somewhat strict regulations regarding homeschooling. You are required to notify the government, teach state-mandated subjects, and there are assessment requirements.  Read more here.

  1. I’m planning on buying a 160 acre lot of undeveloped land in Las Animas county and putting a 14×30 prefabricated Tuff Shed on it to store my hunting stuff and use as a temporary cabin while hunting. Will be using a small wood stove to heat it, a water storage container for water, a composting toilet and generator power for lighting. No hookup to commercial power or water. Does anyone know if there is special permits or anything I need for that?

  2. It sounds like a public “help” forum is in order. I just spent 3 hours researching cisterns, only to read this article that says you can only have 2 rain barrels? Who can survive on 2 rain barrels?

    • I’m going to piggy back off of this one cuz i have property in Fremont County and I just got a letter of contact. Saying I’m out of code due to allegations of “RV Junk yard, over 4 dogs and multiple none moving vehicles, oh and living in an RV.”

  3. When the article says “Saquache County has no codes” what exactly does that mean? I can start digging out a foundation and pour concrete without dealing with the county? No blue prints, etc?
    Anyone know?


    • No, definitely not. Those counties do not have ZONING laws. This means you don’t have to worry about things like getting in trouble for having too many chickens or using more than X% of your land for outbuildings and whatnot.

      Statewide building codes still apply, even if the county doesn’t have inspectors or enforce them.

  4. I’ve decided to live in Archuleta County near Pagosa Springs. I’m going to buy at least 35 acres and build as off grid as I’m allowed. Any tips, contacts or opportunities are welcome. My wife is a doctor and I’m a technologist and we are going to build our forever homestead as well as a healing center for people to come and recover from trauma. We’ll have programs for individuals and families. We will especially welcome vets and people from underserved communities. Thanks!

    • I’m looking in the same area. From West of Durango to Del Norte. I’m a builder and plan on building myself. Maybe 1000-1200 sqr foot. Finding affordable land is tough-especially since it’s usually a cash deal.

  5. I have found a property in Routt County I am considering: Has town water rights, no covenants, and is almost 40 acres. I want to put two tiny homes on the property: one for my son (who will be 18 next month), and one for myself. (Possibly one more for my dad.) Want to use Solar and Wind for power. Still need to look into “sewage” options though. What do you think?

  6. Anyone know about Park County and disconnecting from the grid? Irea is our power company, and they suck mightily- we want to go 100% wind and do away with them completely. Any info would be greatly appreciated.

    • Park County is not friendly to disconnecting from the grid. After 3 years of trying to fight it and modify I have given up and am seeking land elsewhere now.

    • Park county has always been a pain to deal with. I think they change their codes every week. I talked to a mobile home dealer in Colorado Springs and they said they would not take a home to Park county.

  7. The bad thing is they will sell you the land and give you no info on the laws I just bought land in the san luis valley and now have found for me to pull in my new self contained RV for the cooler summers I will have to install a septic and water access around 15K more to spend when I spent every thing I had to acquire the land. Looks like Im going to have to leave the land vacant and move on. Its sad as In retired and on a fixed income. Now I know why the area is full of shacks, drug addicts, law breakers.

    • There’s cheap and some free ways to get a water supply and system going I’ve been doing my research for over a year now cause I bought land in Castillo county Colorado myself… Hey neighbor don’t give up maybe we can help each other through this process and life’s journey as seasoned woman…

  8. Would it be possi or to share this info in a pdf? I would like to use it as a template for things I need to research in my own state.

    • You can copy/paste the article into a Word document and then click “Save as PDF.” We are working on guides for all the states, so be on the lookout for those. It might take us a while to get to your state though since these require a ridiculous amount of searching through legal documents! 🙂
