Utah Off Grid Laws: An In-Depth Guide

Are you thinking of moving to Utah to live off grid? Before you start looking for land, make sure you understand Utah laws about off grid living. Here’s what you need to know about zoning, power, waste treatment, and water rights laws.

Is Living Off-Grid Legal in Utah?

Living off grid is usually legal in remote parts of Utah. However, some areas of Utah require you to connect to the municipal sewer system, effectively making it illegal to live completely off grid. In addition, getting water rights in some parts of Utah is impossible, which can limit your ability to live off grid.

Utah Zoning Laws and Off-Grid Living

Zoning laws in Utah will ultimately determine what is legal or illegal on your property.

It is common, for example, to find zoning laws minimum dwelling sizes  – thus making tiny homes and mobile homes illegal. You’ll also find zoning laws about the number of allowed farm animals, landscaping requirements, setbacks, and the types of businesses permitted.

Land zoned as agricultural in Utah tends to have the least restrictions. However, agricultural land often has minimum parcel sizes. This can make it expensive to go off grid since you must buy a large plot of land.

Building Codes in Utah

All properties in Utah must meet the State building codes. In particular, the fire codes can be pretty strict and make some off-grid structures or systems illegal. Even if your county doesn’t enforce codes, they still exist. The county could always decide to start enforcing codes later on, thus creating a legal nightmare for you – so disobey building codes at your own risk.

Off-Grid Electricity in Utah

Off-grid electricity is legal in Utah. You need a permit to install solar panels, but the permitting process is generally relatively simple. Installing your own solar panels is generally legal, but you will have to get a licensed electrician to do it. You will also need to have an inspection after the solar power system is installed.

Using wind power legally in Utah is often much more difficult. Many areas have zoning ordinances prohibiting wind turbines over 35 feet, establishing setbacks, and noise limits. Some counties also have other restrictions, such as requiring property owners to have insurance for their wind turbines.

Off-Grid Water Laws in Utah

Almost all of Utah is under severe drought, and many water reservoirs are dangerously low. As a result, it is difficult or even impossible to get a water-use permit in many parts of the state. This could make it impossible to go off grid legally in Utah.

Who owns the water in Utah?

All water in Utah is owned by the public but regulated by the state.

To determine who can use water, Utah uses the Doctrine of Prior Appropriation: whoever puts the water to beneficial use first has the right to use the water.

When multiple people claim a limited water supply, the senior water rights holder gets priority use. To keep a water right, the water must be put to beneficial use (“use it or lose it”).

How to get water rights in Utah

Before using any water in Utah – including water on your property – you must apply for a right to appropriate the water through the Utah State Engineer. The process involves filling out a form, providing details about how you intend to use the water, and paying fees. The next step is filing a public notification about your intent to appropriate water. If anyone files a protest, a public hearing will be held.

Areas closed to new water appropriations in Utah

Because of drought conditions and overuse, some areas of Utah are completely closed off to new water appropriations. You won’t be able to legally use water in these areas, even for small appropriations like domestic wells. There were even cases where towns had to stop construction projects that required water connections – the towns didn’t have enough water available.

It’s also worth noting that the law allows the government to remove water rights. So, even if you get a water right and are a senior rights holder, you might not be allowed to use that water during a drought.

Surface Water Laws

Because Utah uses the Doctrine of Prior Appropriation, you do not automatically have the legal right to use water on or next to your property. You must first apply for a right to appropriate the water. Don’t be surprised if someone else already has rights to that water, making it illegal for you to use.

Digging a Pond on Your Property

Under Utah law, even small ponds are considered dams. You must get a permit from the State Engineer before beginning construction. You must have a right to appropriate water before applying for the dam permit.

Well Water Laws in Utah

Under Utah law, you must have a right to appropriate water before constructing a well. In some parts of the state, it is impossible to get a water right – even for small domestic wells – because of water scarcity.

All wells deeper than 30 feet must be constructed by a Utah Licensed Well Driller. Pumps must be installed by a Licensed Pump Installer. However, there is a loophole that allows you to install and repair a pump on your own property.

Rainwater Harvesting Laws in Utah

Utah is notorious for having some of the strictest rainwater harvesting laws in the country. Under the law (Utah Code 73-3-1.5):

  • You are allowed to have rainwater storage of up to 2,500 gallons.
  • If you have more than two covered rain containers with a maximum capacity of 100 gallons each, you do not need to register your containers.
  • Systems larger than 2×100 gallons must be registered. Registration is free.
  • Only one underground storage container is allowed.

Sewage and Waste Removal Laws

As is the case in most states in America, Utah has stringent laws about sewage and wastewater disposal. In many counties, you are even required to connect to the municipal sewer system if one is located nearby (even if you have an approved septic system) – essentially making it illegal to go entirely off grid.

The law rarely allows outhouses and does not make provisions for alternative off-grid systems such as compost toilets.

You can find the full Utah onsite wastewater rules here.

Septic Laws

If you are not connected to the municipal sewer system in Utah, you will most likely be required to install a septic tank. With few exceptions, licensed professionals must install and pump all septic tanks. The minimum septic size in Utah is 1,000 gallons for residential homes with up to 3 bedrooms. Add an additional 250 gallons for each bedroom.

Compost Toilets

Utah’s onsite sewage treatment law currently does not mention compost toilets. The law does allow “alternative systems” – but you must get a permit first and have the system installed by someone with Level 3 certification. Even then, the law is written in a way that prohibits alternative systems unless all wastewater regulations are met. This essentially makes it illegal to use just a compost toilet. If you want to use a compost toilet, you must dispose of the waste in an approved manner, usually septic.

Are Outhouses Legal in Utah (Pit and Vault Privies)?

Under Utah State law, vault and pit privies are legal. However, they are only allowed for “temporary or limited use in remote locations where provisions for water supply or wastewater disposal pose a significant problem.”

It is up to the local health officer to determine whether to issue a permit for a privy. Unless the privy is for temporary use or a recreational camp, it’s unlikely that you will get a permit. Strict rules about setbacks and design must also be met.

Greywater Laws

In 2020, Utah revised its laws on greywater recycling systems. Under the old law, greywater systems had to use a surge tank and pump, and the permit cost $350. The new law allows for simpler, cheaper systems where it is legal to use gravity-fed branched drain systems to pump greywater onto landscaping directly. The permit now costs just $100 in most areas.

The new law does not allow you to discharge laundry waste. There are also stricter rules for multi-family and commercial properties (Tier 2).

  1. We live in Utah and have been fighting the state with almost everything to go off grid. But our biggest fight is the power company. Though we can go solar we are required by state law that was implemented, backed, and forced by Rocky Mountain Power states all homes MUST be connected to the power system even with solar panels. Rocky Mountain will take all the power generated by the solar panels, and then sell it back to the home owner. Also the state, county, or local municipality owns all water rights even on your own land; that means someone down the road can buy your water rights under your house and you can use it. This state is the worst for trying to live off grid and homestead.
