Can you live off-grid in Hernando County, Florida?
89
of 100
Good with caveats
Yes, with two things to plan around. Water is easy here, with about 54 inches of rain a year and wells near 140 feet. The U.S. Forest Service rates wildfire risk high in parts of the county, so plan cleared ground around the house. NOAA counts two hurricane-strength storms within 50 miles since 1975, so build to the wind code and plan for long outages.
What the land says
Rain
Rain can supply much of a household's water with a large tank. The sandy soil dries fast, so plan to water the garden.
About 54 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 140 feet deep; a well typically runs $6,000 to $13,000
Growing season
Long enough for a spring and a fall garden.
About 317 frost-free days, USDA zone 9b; last frost about February 8, first about December 10
Sun
Strong sun. A modest solar array covers a household.
About 5.5 hours of full sun a day, averaged over the year
Flood
Flood zones run along creeks and rivers here. Look up the parcel on FEMA's flood map.

Storms
Expect about one hurricane within 50 miles over 30 years. Build to the wind code and keep a week of fuel and water.
NOAA: two hurricane-strength storms within 50 miles since 1975; about 0.3 strong (EF2 or stronger) tornadoes a decade within 25 miles
Terrain
Flat to gentle, easy to build on.
Slopes average about 4%, about 100 feet above sea level
Soil
Sandy and fast-draining. Septic may need an extra treatment step, and garden beds need compost to hold water. The county's soil test decides.
Sand, well drained (USDA soil survey). A standard system typically runs $5,000 to $10,000
Road
Paved roads are close by.
Nearest paved road usually within about 0.5 miles (OpenStreetMap)
