Septic Systems and Real Estate in Florida

About 30% of Floridians use a septic system, according to Florida DEP, so many home sales include one. This page covers what buyers and sellers should know: the law on inspections at sale, what an inspection checks and costs, which records to ask for, and the local rules that can change the cost of owning the system. It is general information, not legal advice.

The law on inspections at sale

Florida law bars any government from requiring a septic inspection when a home is sold (s. 381.0065(4)(x), Florida Statutes). A buyer, a lender or the sales contract can still call for one. A 2010 law created a statewide septic inspection program on a 5-year cycle, but it was delayed and then repealed in 2012.

A buyer can ask for a septic inspection as part of the purchase. Ask your real estate agent or attorney whether to make the sale contingent on one.

What a septic inspection covers

An inspection checks the tank, its baffles and the drain field and records sludge and scum levels. The EPA recommends one at least every three years. Florida law bars any government from requiring one when a home is sold; a buyer, a lender or the sales contract can still call for one.

A typical inspection includes:

• Locating the tank and opening the lids
• Measuring sludge and scum
• Checking baffles, filter and drain field
• A written report
• Pumping, if included in the quote

How it usually runs:

1. The inspector finds the tank and opens the lids.
2. Sludge and scum levels are measured, and the baffles and filter are checked.
3. The drain field is walked and checked for wet spots or odors.
4. For a full inspection, the tank may be pumped so its walls can be seen.
5. You get a written report.

What an inspection costs

Item	Typical range
Full real-estate septic inspection	$300–$650
All inspections, routine visual check to full inspection	$100–$650
Camera inspection of the lines	$125–$500
Septic tank pumping, if not included	$290–$600
Locating and digging up buried lids	$50–$200

These are planning ranges from published cost guides, not quotes. Ask each company what its price includes, especially whether the tank will be pumped. For more detail, see our septic cost calculator.

Questions to ask the inspection company:

• Will you pump the tank as part of the inspection?
• Will you check the drain field, or only the tank?
• What will the written report include?
• How soon will I get the report before closing?

Records to ask for

Septic permits are handled at the county level. In most Florida counties, the county health department issues them on behalf of Florida DEP. In Marion County, DEP has issued them directly since July 1, 2025. That office is the place to ask for the permit and inspection records of an existing system. Find yours on Florida county septic permit offices.

• Online: some counties post records online. Hillsborough County's health department, for example, uses eBridge for recent permit and inspection information.
• By request: if the county office can't help, you can make a public records request to the Florida Department of Health (PublicRecordsRequest@FLHealth.gov or 850-245-4005). Its page lists copies at 15 cents per single-sided page and waives fees of $5 or less.
• From the seller: ask for pumping receipts, repair invoices and any past inspection reports.

When you look at the file, check that the permit matches the house as it is today, and ask whether it shows where the tank and drain field are. If the file is thin or missing, ask the office what it holds.

If the home has an aerobic unit (ATU)

An aerobic treatment unit comes with ongoing duties under Florida law, so a buyer may want to ask about them before closing:

• Operating permit: an ATU needs an operating permit, valid for 2 years and then renewed. Ask when it expires.
• Maintenance contract: the owner must keep a service agreement with a maintenance entity that inspects the unit at least twice a year (an owner-occupant may instead be permitted to maintain it after manufacturer-certified training, so ask who does the maintenance). Ask for the current contract and recent service reports, and whether the contract can be moved to the new owner or a new one is needed.
• Running cost: maintenance contracts run about $175–$600 a year in published ranges, with chlorine and parts often extra.

Springs-area rules that can affect a purchase

In some springs protection areas, a failing system cannot simply be repaired the old way. The repair has to include an upgrade to a nitrogen-reducing system, which can change what a future repair costs. Two areas matter in this directory's region:

• Silver/Rainbow springs (parts of Marion, Lake, Alachua, Putnam, Sumter and Levy counties): DEP's August 2026 table says repair or modification permits on any size lot in the BMAP require a nitrogen-reducing system. The updated plan became final and effective on April 27, 2026, and DEP lists the same any-lot-size rule for new systems as of July 27, 2026.
• Wekiwa-Rock Springs (Orange County): since March 1, 2025, a repair or modification permit on a lot under 1 acre in the Priority Focus Area requires an upgrade to a system that removes at least 65% of nitrogen, according to Orange County. The county's incentive program pays up to $10,000 toward an upgrade for eligible homes in unincorporated Orange County served by Orange County Utilities.

To see whether a property is in one of these areas, search the address on DEP's Springs BMAP and HB 1379 requirements map, then confirm with the permit office. The full rules are on Florida septic regulations for homeowners.

Questions for the seller

• When was the tank last pumped, and by which company?
• How big is the tank, and where are the tank and drain field?
• Has the system ever been repaired or replaced? Was a permit pulled?
• Have you had backups, slow drains, odors or wet spots in the yard?
• Is it a conventional system or an aerobic unit? If aerobic, who holds the maintenance contract?
• Has anything been built, paved or planted over the drain field?
• Is sewer available on the street, and has the county or utility said anything about connecting?

For sellers

No government can require a seller to have the system inspected, though a buyer, a lender or the sales contract can still call for one. Having recent pumping and inspection records ready can answer buyer questions early. Florida DEP registers septic tank contractors; you can check any company on DEP's lookup using how to verify a Florida septic contractor. Ask your agent or attorney what you must disclose about the property.
