Off-Grid in Highlands County, Florida.
27.34° N · 81.34° W · pop. 101,235 · seat: Sebring
Verdict
Workable
for off-grid use
The honest take
Highlands County is a workable but constrained off-grid option in central Florida. Solar is solid — Sebring averages 5.56 kWh/m²/day annual, better than the US average and genuinely useful for a modest off-grid system. Water is county-wide and generally accessible through the Floridan Aquifer (USGS SIR 2010-5097). The county's Land Development Code follows the typical Florida pattern: RVs are restricted to licensed parks, and using one as a residence on your own vacant land requires navigating the LDC's use provisions. Florida Building Code 8th Edition applies county-wide — any permanent shelter needs wind-load engineering for 120+ mph. Land is not cheap by off-grid standards: Land.com reports a median $22,745/acre, and the average lot size is 80+ acres, meaning smaller off-grid parcels are competing with agricultural-scale buyers. If your goal is Florida off-grid with strong solar and reliable water, Highlands County is workable. If your goal is minimal regulation and $2,000/acre land, it is the wrong county.
Why Highlands County earns this verdict
- Solar irradiance averages 5.56 kWh/m²/day at Sebring — solid for Florida and useful for an off-grid system (monthly range 4.87 July to 6.09 March).
- The Floridan Aquifer underlies the entire county; USGS SIR 2010-5097 documents the hydrogeology in detail, with the top of the aquifer ranging from <200 ft (NW) to >600 ft (SE).
- Highlights County LDC follows the FL pattern: RVs restricted to licensed parks; living in one on your own lot is not permitted outside specific use provisions.
- Florida Building Code 8th Edition applies county-wide — any permanent shelter must meet wind-load requirements (Highlands is inland but still rated for hurricane winds).
- Land.com reports a median $22,745/acre with 80+ acre average lot sizes — smaller off-grid parcels are scarce and compete with citrus/ag buyers.

What you'll spend
Raw land (5–20 ac)
$10,000–$25,000 / acre
· Land.com $22,745/ac is an all-listing aggregate; rural acreage parcels compete with ag buyers
Off-grid solar (5kW)
$15,000–$22,000
· 5.56 kWh/m²/day — modest system needed
Drilled well + pump
$6,000–$15,000
· Confined Floridan; deeper than North FL wells
Septic system
$6,000–$15,000
· Standard tank/leach; perc test required
Power grid extension (if not full off-grid)
$5,000–$20,000
· Duke Energy territory; distance-dependent
Total realistic baseline
$70,000–$180,000

What to verify before you buy in Highlands County
- The LDC restricts RV-as-residence to licensed parks; living in an RV on your own vacant land is not permitted without navigating use provisions. Budget for a permitted structure — not a camper.
- Florida Building Code applies county-wide, including wind-load engineering for hurricane-rated winds. Highlands is inland (50+ mi from either coast) but still rated.
- The Floridan Aquifer is accessible but deeper in southern Highlands County (600+ ft to the top of the aquifer). Well costs vary significantly by location.
- Land.com's $22,745/ac median and 80+ acre average lot sizes mean the typical listing is a farm or ranch, not a 5-acre off-grid parcel. Smaller lots are scarcer and may carry a price premium.
- Flood zones: the Kissimmee River and Lake Istokpoga have floodplain designations. Check FEMA FIRM for any low-lying or lake-adjacent parcel.
- Wildfire risk in Lake Wales Ridge scrub habitat is real — the ecosystem is fire-adapted and prescribed burns are common. Insurance in scrub-adjacent areas may be higher.
- Ag zoning dominates rural Highlands. Verify agricultural classification vs. residential zoning — some parcels marketed as land may have active citrus leases or conservation easements.

Strong solar, cheap high-desert land, owner-finance market. Outside AMA boundaries — fewer water restrictions than FL. Land under $3,000/acre.
Navajo County, AZ
Outside AMA, $2,250/ac median, active owner-finance, good solar. Elevation gradient gives cooler summers than Highlands. 1,300+ listings.
