Major concerns

Possible, but hard and costly. Only about 9 inches of rain falls a year, so you will rely on a well or hauled water. The growing season runs about 288 frost-free days, long enough for a spring and a fall garden. The sun is strong, about 6.6 hours of full sun a day, so a smaller solar array covers a household.

Is it legal here?

Zoning
Pinal County zones land outside its towns and publishes its zoning map. Our free lookup shows the district for any address.
Building code
No statewide residential building code: each county and city decides whether to adopt one, and a county may exempt land zoned rural or unclassified. State law still requires a county building permit for any building or addition costing over $1,000, even where the county has no code.
Rainwater
Collecting it is allowed.
Composting toilets
Allowed.
Water rights
Water belongs to whoever claimed it first. A new well or pond may need a state permit, and a creek may already be claimed.
