Well, Septic & Utilities: What to Check Before Buying Rural Florida Land

City lots come with water, sewer, and power at the curb. Rural land usually doesn't. If you're buying acreage in Florida's interior, you're likely looking at a well, a septic system, and a power line that may be a long way off. Each one can be routine or a dealbreaker, and you want to know which before you close.

About 30% of Floridians already rely on septic systems, roughly 2.6 million of them statewide (UF/IFAS). So this is normal territory. It just takes homework.

Key Takeaways

• A septic system (officially an OSTDS) needs a passing soil and site evaluation before the county will permit one.
• In the eight counties we serve, your county health department handles septic permitting.
• A well permit is required before drilling, through your regional Water Management District (SFWMD for most of South Florida).
• Rural electric line extensions are priced per parcel. Get a written estimate before you offer.

Will the land support a septic system?

This is the first question on most rural lots, because no septic means no house. In Florida, septic systems are called OSTDS (onsite sewage treatment and disposal systems), and a permit requires a soil and site evaluation that checks soil type, topography, and the water table (Florida Department of Health). If the lot can't drain properly, it won't "perc," and you can't build as planned.

The technical rule: the bottom of the drainfield has to sit at least 24 inches above the wet-season high water table, so effluent filters through unsaturated soil (UF/IFAS). Where that separation isn't possible, you may need an engineered or mounded system, which costs more. Always make a passing site evaluation a condition of your purchase.

One note on who to call. Oversight of Florida's septic program moved from the Department of Health to the Department of Environmental Protection under the 2020 Clean Waterways Act. But in the counties we serve, the local county health department still handles septic permits and inspections, so start there.

Can you get a well, and is the water good?

Most rural Florida homesites draw water from a private well. You need a well construction permit before anyone drills, issued by your regional Water Management District or its delegated county health department (South Florida Water Management District, Rule 62-532). A single-family domestic well doesn't need a separate water-use permit.

Quality and quantity both matter. Florida doesn't require routine testing of private wells, which puts it on you: the Department of Health recommends testing for bacteria and nitrate at least once a year. In the southern coastal counties, shallow wells tap the Biscayne aquifer, the sole drinking-water source for over two million residents, while the deeper Floridan aquifer is brackish here and usually needs treatment (USGS). Test any existing or proposed well before you rely on it.

How far away is the power?

Electric is the utility buyers most often underestimate. When a line has to be extended to reach your building site, Florida utilities charge a Contribution in Aid of Construction, a customer-paid cost set by Florida Public Service Commission rule (Rule 25-6.064). The farther your site sits from existing lines, the higher that cost runs, because one home's revenue won't offset a long extension.

There's no published flat rate, so don't trust a number off the internet. Request a written estimate from FPL or your local co-op for the specific parcel before you commit.

What about public water and sewer?

If a parcel sits inside a utility's service area with mains at the lot line, you may be able to connect to public water and sewer instead of installing well and septic. That route trades drilling and drainfield costs for impact and connection fees, which vary widely by county. Contact the county utility for the parcel's fee schedule so there are no surprises.

Put it in the contract

The theme here is simple: confirm before you close. Make septic feasibility, well permitting, and utility access inspection-period contingencies, so you can walk away if the lot won't perc, the well permit is denied, or the power extension is too expensive.

Frequently asked questions

What does it mean for land to "perc"?

"Perc" refers to whether the soil drains well enough to support a septic drainfield. Florida requires a soil and site evaluation that checks the soil and water table, and the drainfield must sit at least 24 inches above the wet-season high water table (UF/IFAS).

Who issues septic permits in Florida?

Statewide oversight sits with the Department of Environmental Protection, but in most counties, including the eight we serve, the local county health department handles septic (OSTDS) permitting and inspections. Start with your county health department.

Do I need a permit to drill a well in Florida?

Yes. A well construction permit is required before drilling, repairing, or abandoning any well, issued by your regional Water Management District or its delegated county health department (SFWMD, Rule 62-532).

How much does it cost to run power to rural land?

It varies by parcel and distance from existing lines, so there's no flat rate. Florida utilities charge a customer-paid Contribution in Aid of Construction (PSC Rule 25-6.064). Get a written estimate from the utility for your specific lot.
