The Truth About Living Off Grid: 5 Years In The Desert
Finding the Right Land
Choosing the perfect land for off-grid living means taking a close look at regional factors like weather and terrain. These elements play a big role in determining how well a property fits your needs.
Arizona Weather and Land Types
Arizona offers a variety of climates and landscapes. In the south, you’ll find desert regions where summer temperatures often soar above 100°F. Northern and eastern areas, on the other hand, feature mountainous regions with cooler weather. Central Arizona is mostly flat plains, which are ideal for development projects.
Each type of terrain comes with its own set of pros and cons:
| Terrain Type | Advantages | Challenges |
|---|---|---|
| Desert Land | Affordable, easy to develop, excellent for solar energy | Extreme heat, scarce water |
| Mountains | Cooler temperatures, natural wind resources | Tougher construction, steep terrain |
| Flat Plains | Easy to build on, great for large systems | Risk of soil erosion, constant sun exposure |
| Rolling Hills | Scenic views, balanced terrain | Moderate construction challenges |
Testing Soil for Growing Food
Soil quality is another critical factor, especially if you’re planning to grow your own food. Arizona’s alkaline soils need testing to ensure they can support a sustainable garden. A basic soil health test runs about $66, while a comprehensive analysis costs up to $162. When testing, focus on these key metrics:
- pH levels: Aim for 6.5 to 8.0, suitable for many desert-friendly plants.
- Nitrogen: Look for concentrations between 10–20 parts per million.
- Phosphorus: Ideal levels range from 5–15 parts per million.
- Potassium: Target 80–150 parts per million.
To test, collect soil samples from multiple spots, digging 6–12 inches deep. Mix the samples thoroughly and send about two cups of the mixture to a certified lab for analysis. Proper soil preparation can increase crop yields by 8–10%.
Checking Sun Exposure
Solar energy is a major asset in Arizona, which ranks 5th in the nation for solar capacity. Solar power already supplies energy to over 1.4 million homes statewide. As GreenLancer notes:
"Peak sun hours are a key factor to consider when you have a solar energy system. The amount of sunlight your solar panels receive directly affects their efficiency."
To maximize solar potential, evaluate the property’s orientation and check for natural features that might block sunlight. Consider seasonal changes in sunlight and, for sloped properties, focus on south-facing areas to optimize energy collection.
Water Rights in Arizona
Securing clear water rights is essential for successful off-grid living in Arizona. Not only does it ensure compliance with state laws, but it also guarantees a reliable water supply for your sustainable lifestyle. Arizona’s unique water regulations demand careful planning to make this work.
Water Laws and Required Permits
Arizona operates under the "prior appropriation" doctrine for surface water rights. This means older claims on water take precedence over newer ones. If you plan to use surface water, you’ll need to obtain the necessary permits and verify that no prior claims exist.
When it comes to groundwater, the rules differ depending on location. In Active Management Areas (AMAs), stricter permits are required, while areas outside AMAs have more lenient guidelines. For wells pumping up to 35 gallons per minute, you’ll need to file a 55-40 Notice of Intent to Drill. If your property is 5 acres or smaller and the water is for domestic use, the county health authority must review the application before it’s submitted to the Department of Water Resources.
Once you’ve navigated the legal aspects, the next step is to explore rainwater harvesting as a sustainable water source.
Setting Up Rain Collection
Rainwater harvesting is a practical and legal option for off-grid properties in Arizona – and it’s even encouraged by state policies. For example, a 1,000-square-foot roof in an area with about 10 inches of annual rainfall can collect over 6,000 gallons of water.
To ensure your rain collection system complies with regulations, it should include the following components:
- Storage Containers: These must be ANSI/NSF certified and opaque to prevent algae growth.
- Inlet Screens: Fine mesh screens help block debris and pests.
- Overflow System: Designed to handle excess water efficiently.
- Conveyance System: Typically made of PVC or aluminum to direct water flow effectively.
In 2010, Tucson became the first U.S. city to mandate rainwater harvesting systems for new commercial buildings, requiring them to provide at least 50% of the water used for outdoor irrigation.
Water System Costs
After securing water rights and setting up a collection system, it’s time to think about costs. Fortunately, Arizona counties offer financial incentives to ease the burden:
- Level 1 Grants: Up to $500, covering 50% of the cost for basic rainwater systems.
- Level 2 Grants: Up to $2,000 for more advanced systems, with funding based on cistern capacity.
For added reliability and cost efficiency, combining rainwater harvesting with a well can be a smart move.
Zoning Rules and Permits
If you’re planning to live off-grid in Arizona, understanding zoning laws is a must. Each county has its own set of rules, dictating everything from the size of your home to the permits you’ll need. Let’s dive into county-specific zoning details and the steps required for securing building permits.
County Zoning Rules
Arizona counties generally adhere to the International Residential Code (IRC) for tiny homes and off-grid structures. For instance, Cochise County requires a minimum dwelling size of 296 square feet, while Coconino County caps tiny homes at a maximum of 600 square feet.
Here’s a quick overview of zoning requirements in some popular off-grid counties:
| County | Minimum Size | Ceiling Height | Additional Rules |
|---|---|---|---|
| Mohave | 170 sq ft | 6’4" | Yurts allowed with proper septic |
| Pima | 200 sq ft | 6’4" | Maximum size of 400 sq ft |
| Maricopa | 200 sq ft | 6’4" | Insulation required |
In Mohave County, properties zoned as "AR" (Agricultural Residential) or "UNDET-RURAL" allow temporary residences, such as RVs, provided that septic permits are maintained annually.
Building Permits for Off-Grid Homes
The process for obtaining building permits varies by county, but the general steps are fairly consistent. Here’s what you can expect:
- Initial Planning
Submit detailed site plans that include the property layout, planned structures, and system placements (like septic or water catchment). For example, in Apache County, you’ll need a septic permit from the Environmental Health Department. This typically costs $300 for standard systems or $550 for alternative setups. - Required Documentation
Be prepared to provide the following:- A completed building application with detailed construction plans
- A site plan or property map
- Septic system documentation
- 911 address verification
- Off-grid utility waivers
- Construction and Inspections
Throughout the building process, regular safety inspections are required. In Apache County, for instance, septic systems must be completed within two years, with several mandatory inspections along the way.
Some exemptions exist for smaller structures. In Apache County, you won’t need permits for:
- One-story detached buildings under 200 square feet
- Fences less than 7 feet high
- Retaining walls under 4 feet
- Water tanks on grade holding up to 5,000 gallons
The final step is obtaining a Certificate of Occupancy, which confirms your off-grid home complies with all local building codes and is safe to live in.

Here are some natural cooling strategies to consider:
- Install window shades
- Use ceiling fans
- Plant shade trees
- Explore hybrid cooling systems
"Evaporative cooling is a cost-effective way to cool air by using water evaporation, perfect for desert areas. It’s especially good for dry places like Lake Havasu, AZ, where the dry and wet-bulb temperatures make it work best."
– Dustin Hufsey, President, One Hour Air Conditioning & Heating Kingman
To enhance efficiency, make sure all windows and doors are sealed tightly. Regular maintenance, like cleaning water tanks and replacing filters, will also keep your cooling systems running smoothly.
Water and Waste Systems
Living off-grid in Arizona means tackling water reuse and waste management head-on, especially with the state’s dry climate and specific regulations. Efficient systems are a must to ensure sustainability and compliance.
Greywater Systems
Arizona makes it relatively easy for off-grid homeowners to reuse greywater. If you keep usage under 400 gallons per day and limit it to landscape irrigation, no permit is required. This can significantly cut down water needs – greywater accounts for about 27% of total water usage in Tucson, potentially saving a family of four over 100 gallons daily.
One popular option in Arizona is the laundry-to-landscape system. It’s straightforward, legal, and doesn’t require a permit if installed properly.
Key points for setting up your greywater system:
- Water Sources: You can safely use water from bathroom sinks, showers, and washing machines. Avoid kitchen sinks, dishwashers, and toilets due to health risks.
- Product Choices: Stick to biodegradable soaps and detergents without salts, boron, or bleach. As David Sedlak, a civil and environmental engineer, explains, “To take gray water to the next level, we’re going to have to pay a little bit more attention to the quality of the water and the types of products that we use inside of our homes”.
- System Design: Use diverter valves to direct water to either the sewer or your yard, install lint filters for laundry water, and create mulch basins for subsurface irrigation. Avoid spray irrigation methods.
- Maintenance: Inspect the system monthly and flush the lines quarterly. During cooler months, redirect water to the sewer since plants need less irrigation.
While greywater systems help cut down potable water use, managing waste is another crucial component.
Composting Toilets
For off-grid living, composting toilets are a practical solution, especially where water is scarce or septic systems aren’t an option. The Arizona Department of Environmental Quality (ADEQ) approves specific designs like 55-gallon barrel systems and masonry chamber systems.
Here are some top composting toilet options:
| Toilet Model | Price Range | Capacity | Key Features |
|---|---|---|---|
| Green Toilet 330 | ~$1,495 | 800 uses | Batch system, odor-free, spare container |
| Nature’s Head | $1,025–$1,071 | Medium | Popular choice, good ventilation |
| Separett Villa 9215 | $989 | Medium | Urine separation system |
| Sun-Mar GTG | $639 | Basic | Budget-friendly option |
Batch composting toilets like the Green Toilet 330 are particularly efficient. They use multiple containers, making maintenance easier and extending capacity to around 800 uses. These systems also separate liquids from solids, which is key for controlling odors.
Ventilation is another critical factor in Arizona’s heat. Most systems rely on natural airflow, but you can boost it with electric fans, Whirlybirds, or solar-powered fans for indoor setups.
With waste systems in place, the next step is planning effective water storage.
Water Storage
Arizona’s harsh weather and limited rainfall make proper water storage essential. Southeastern Arizona’s high desert gets just 12 inches of rain annually, most of it concentrated over 2.5 months.
How Much Storage Do You Need? Start with a baseline of 10 gallons per person per day for basic needs. Keep in mind that a full 300-gallon tank weighs 2,409 pounds, so choose a solid foundation.
Tank Options and Costs:
- Used IBC tanks: Around $150, often found on Facebook Marketplace, great for beginners.
- Used 55-gallon plastic barrels: About $20 each, ideal for small setups.
- New 2,600-gallon tank: Priced near $2,000, suitable for larger properties.
Water Sources: Options include hauling water (approximately $65 per 1,500-gallon delivery), well water, or rainwater catchment systems. Rainwater collection is especially popular due to Arizona’s monsoon season but requires a higher upfront investment.
Tank Materials: Your choice depends on budget and durability needs. Plastic tanks are lightweight and affordable, while steel tanks hold up better against Arizona’s tough conditions.
Maintenance Tips: Clean tanks annually using white vinegar and a pressure washer. For rainwater systems, install a first flush diverter to filter contaminants from the initial rainfall.
Legal Considerations: Arizona generally supports rainwater harvesting, but local rules can vary by county. Be sure to check specific regulations.
To ensure your stored water is safe to drink, invest in proper filtration and purification systems, especially if you’re combining multiple water sources in your off-grid setup.
Next Steps
Embarking on your off-grid adventure in Arizona requires careful planning and a strong focus on the basics, all while ensuring you comply with local laws. After selecting your land, the next steps involve securing permits and laying the groundwork for a self-sufficient lifestyle.
Start with a dependable water source. Elisabeth Beauchamp, Senior Staff Writer at Today’s Homeowner, emphasizes:
"If you’re planning to live off the grid, securing a reliable water source is priority number one".
For a family of four, you’ll need about 200–400 gallons of water daily to cover drinking, cooking, cleaning, and bathing.
Tackle permits and regulations early in the process. Arizona operates under a home rule system, meaning each municipality has its own building codes. If you’re in Greenlee County, you’re in the only area without residential building codes. Wherever you are, you’ll need to submit a detailed site plan outlining your property layout, structures, and systems like septic and water catchment. Expect to apply for permits covering construction, electrical, and plumbing work. If your project impacts local ecosystems or water resources, additional environmental approvals might also be required.
Plan your energy needs thoroughly. Once your permits are in place, start designing systems that match your energy and water requirements. Begin by listing essential energy needs like heat pumps, appliances, and lighting. Then, move on to other important devices such as refrigerators and washing machines, and finally optional items like TVs and dishwashers. Experts recommend meticulous planning to avoid setbacks.
Start small and grow gradually. Begin with manageable systems – install a rainwater barrel or a solar charger to get started. As you expand, hire professionals for more complex installations, especially electrical systems. This ensures compliance with local codes and guarantees safety.
