Can you live off-grid in Pittsburg County, Oklahoma?
88
of 100
Good with caveats
Yes, with two things to plan around. Water is easy here, with about 46 inches of rain a year and wells near 60 feet. The U.S. Forest Service rates wildfire risk high in parts of the county, so plan cleared ground around the house. Septic will likely cost more, because rock or a hard layer sits about 15 inches down.
What the land says
Rain
Rain can supply much of a household's water with a large tank. A garden mostly waters itself in normal years.
About 46 inches a year (PRISM, 1991 to 2020 average)
Wells
Shallow wells, so drilling should be one of the cheaper costs.
The typical well here is about 60 feet deep; a well typically runs $4,000 to $9,000
Growing season
A full season for most vegetables.
About 227 frost-free days, USDA zone 7b; last frost about March 29, first about November 11
Sun
Good sun. Size the array and battery bank for winter.
About 5.2 hours of full sun a day, averaged over the year
