The Septic Permit Desk Moved. Most Homeowners Don't Know Yet.

What actually changed on July 1, 2025

For decades, a Marion County homeowner who needed a septic permit called the Marion County Health Department. That stopped being true on July 1, 2025. Florida's Clean Waterways Act (2020) moved the entire Onsite Sewage Treatment and Disposal System (OSTDS) program from the Department of Health to FDEP, first at the program-office level in 2021, then county by county for field permitting and inspections. Marion County was in that later group, alongside the Panhandle counties, and the switch is complete: FDEP now issues the permits, runs the inspections, and holds the records.

The practical problem this creates is that the old search habit still works, technically. Search "Marion County health department septic permit" and you'll still find a health department page. It just doesn't do this anymore. Homeowners who follow that instinct end up describing their project to an office that has to redirect them, which costs a phone call and a day, right when a backed-up system does not have a day to spare.

Repair permit vs. construction permit: which one do you need?

Not every septic job needs the same kind of permit, and knowing the difference saves a confusing call.

• Repair permit. Required to repair or replace a drainfield or tank on an existing system: a cracked tank, a collapsed lid, a failed drainfield, swapping a component. This is the permit most Marion County service calls end up needing.
• Construction permit (Form DEP 4015). Required for a brand-new system, whether on new construction or replacing a failed system with a full rebuild. This is the more involved filing, closer in scope to the original install permit.
• No homeowner permit. Routine pumping does not require one. A licensed pumper files the disposal manifest for where the waste goes, but that is a contractor filing, not a permit you apply for.

A quick rule of thumb: if water is only coming out of the tank, you're almost certainly in pumping territory and no permit is involved. If something underground is being fixed or replaced, a repair permit almost certainly is. See septic tank repair and drain field repair for what those jobs typically involve.

What an FDEP septic permit actually costs

This is where a lot of confusion comes from, because two different numbers are both true at the same time and they answer different questions.

Those are the actual government line-item fees, set by state law, not an estimate. On their own, a repair permit's government fee typically lands somewhere in the neighborhood of $65-$240 total, review plus a site evaluation if one is required.

The number homeowners more often see quoted, $320-$1,900, is a different and larger figure: the fuller cost of the whole permitting process once a required site evaluation, percolation test, or engineering review is factored in on top of the base government fee. Both numbers are real; they just answer "what does the state charge" versus "what does the whole process typically run." Our full cost breakdown page has the wider picture, including what drives a job toward the top or bottom of that range.

The nitrogen rule that surprises people: PFA and ENR

Much of the Ocala and Silver Springs Shores area sits inside the Silver Springs Priority Focus Area (PFA), the zone FDEP drew around Silver Springs after research tied roughly a third of the nitrogen reaching the springs and the aquifer to septic systems. Inside a PFA, a new system on a lot under 1 acre has to be an enhanced nutrient-reducing system, ENR-OSTDS for short, engineered to cut nitrogen output by at least 65% compared to a conventional system. That upgrade adds roughly $8,000-$20,000 to the job.

Florida's 2023 rule change (HB 1379) widened this beyond brand-new installs: a system being repaired or replaced on a sub-1-acre PFA lot can also be required to go ENR, unless a sewer connection is available within 5 years. That is the detail that catches people off guard, because "I'm just fixing what's already there" sounds like it should be exempt, and on a larger lot or outside a PFA it usually is. Inside a PFA on a small lot, it depends on the specifics of the repair and the parcel.

This is a parcel-by-parcel question, not a neighborhood-wide answer, which is exactly why we check the FDEP PFA map against your address before quoting anything rather than assuming either way. Silver Springs Shores homeowners weighing a repair against the county's separate septic-to-sewer conversion timeline can see the fuller picture on our Silver Springs Shores page. General new-system and ENR mechanics are also covered on our inspections and new installation page.

How the FDEP permit process actually works

The mechanics changed along with the agency. FDEP runs OSTDS applications through its own online portal, myfloridaehpermit.com, rather than a walk-in county office. A typical repair permit path looks like this:

1. Site evaluation, if required. Not every repair needs a fresh evaluation; a straightforward like-for-like fix often doesn't. A significant repair, a drainfield relocation, or anything touching system capacity usually does.
2. Application submitted through the FDEP portal, with the scope of work, site details, and any evaluation results attached.
3. Review and issuance. FDEP reviews the application against Chapter 62-6, F.A.C. (the OSTDS rule chapter) and issues the permit once it's satisfied.
4. Inspection. Work gets inspected before it's covered back up, the same as under the old health-department process.

We handle this filing as part of a repair job rather than leaving it for the homeowner to navigate, in part because the portal and the office both changed in the same year and there hasn't been much time for that to become common knowledge.

What's new for 2026: HB 589, and who it actually affects

A second, smaller change landed in 2026. House Bill 589, effective May 6, 2026, addresses a specific friction point in new home construction: previously, a city or county could refuse to issue a building or plumbing permit for a new house until its separate septic construction permit was fully approved, even though the two processes move at different speeds. HB 589 stops that. A builder can now get the building permit moving by showing proof that a septic construction permit application was submitted, rather than waiting on full approval first. A second provision, effective July 1, 2026, gives applicants a 120-day grace period before a brand-new OSTDS rule can be applied to a permit application that was already in progress when the rule changed.

Worth saying plainly: neither of these changes the process for repairing or replacing a system on a house that already exists. HB 589 is a new-construction sequencing fix. If your project is a tank repair, a drainfield fix, or a replacement on a home that's already standing, the repair-permit path above is still the one that applies to you.

Common permit mistakes we see

• Calling the county health department first. Understandable, since that was correct for years. As of July 1, 2025, it just isn't anymore for Marion County.
• Assuming pumping needs a permit. It doesn't. Don't let anyone tell you otherwise to pad a bill.
• Assuming ENR always applies to a repair. It's a parcel-and-lot-size question, tied to the PFA boundary and lot acreage, not a blanket rule for every repair in Ocala.
• Assuming ENR never applies to a repair. The opposite mistake. On a sub-1-acre PFA lot, a repair or replacement can trigger it under the 2023 rule. Check before you assume you're exempt.
• Skipping the permit on a "simple" fix. A repair permit is required for drainfield or tank repair and replacement work, not just for full new installs. Unpermitted work can complicate a future home sale, since a buyer's inspector or lender can ask for permit records.
• Not keeping a copy of the permit and inspection paperwork. A real estate closing can ask for it years later, and the office that issued it has changed once already. Keep your own copy rather than counting on a future records request going smoothly.

Why this matters more here than most places

Marion County has roughly 90,000 homes on septic, a large share of the county, and a lot of that ground is the Ocala Limestone, the same karst rock formation the Upper Floridan Aquifer is named for. Where limestone sits near the surface, a site evaluation carries more weight than it would somewhere with deep, uniform soil, because it's confirming there's enough soil depth between a drainfield and the rock underneath. That's a separate question from the permit-agency change, but the two are related: FDEP's review process is the mechanism that catches a bad site before a system goes in on ground that can't support it. Getting the permit right isn't paperwork for its own sake here; it's the step that keeps a repair from becoming a redo.

Cut water use, hold off on scheduling a pump-out until you know what's actually happening, and if a repair is on the table, ask whoever you call whether the job needs a repair permit, whether a site evaluation applies, and whether your address sits inside the Silver Springs PFA. A straight answer to all three, before anyone digs, is the actual test of whether you're dealing with someone who knows this year's process.

The kitchen-table promise, permit edition

The same promise applies to permits: a written scope before we file anything, and if your parcel needs a site evaluation or falls inside the PFA, we tell you that up front, not after a surprise fee shows up.
