Florida Septic, Well, Wetland, and Waterfront Checks

Four property questions. Four different files.

Start with the exact address and what you plan to do. A permit, map, inspection, or listing field may answer one question without answering the other three.

Start with one folder

Give every office the same property and the same plan.

You do not need every record before the first call. These four details keep the first answer tied to the right land and the right work.

Exact property
Street address, parcel ID, county, city-limit status, and the best survey or site plan you have.
Exact goal
Buying, repairing, building, adding fill, replacing a system, trimming plants, or closing an old record.
Current service
Public water, private well, central sewer, septic, or a mix that needs to be confirmed.
Existing paper
Old permits, site plans, lab reports, surveys, photos, service records, and agency correspondence.

The four checks

Open only the branch that fits the property.

More than one branch may apply. Keep the answers separate until each office has settled its own part.

Check 1 / Wastewater

Septic

Find the system, the permit path, and any repair or operating file.

Where to start

First confirm that the property is actually on septic. Then use DEP's current permitting path to see whether the address starts with a DEP service hub or the county health department. Do not assume an old permit still names the right office.

What the file can settle

The file can identify the approved system, site plan, installation or repair history, inspections, and any operating permit or maintenance agreement. A sewer connection can also leave an abandonment record for the old tank.

What it does not settle

A septic permit does not prove the system is working today, show every unrecorded repair, or answer a private-well water-quality question.

Check 2 / Drinking water

Private well

Keep construction records, equipment, and water testing in the same file.

Where to start

Confirm whether the home uses a private well or a public system. DEP runs the state well program with Florida's water management districts and local permitting authorities. The address decides the permit path.

What the file can settle

Look for the construction permit, completion record, contractor, well location, pump and treatment papers, lab reports, and any record for an old well that was plugged or abandoned.

What it does not settle

A working pump does not prove the water is safe. Florida Health says private well owners are responsible for their water and recommends bacteria and nitrate testing at least once a year.

Check 3 / Land and drainage

Wetlands and surface water

Use maps for clues. Use the proper determination and permit path for the answer.

Where to start

Review the parcel, survey, aerials, drainage, flood information, and the U.S. Fish and Wildlife wetlands map. Then ask the DEP district or water management district which state review serves the project and address.

What the file can settle

Florida's Environmental Resource Permit path can cover wetlands, other surface waters, stormwater, dredging, fill, and changes to water flow. A state formal determination can set a legally binding wetland boundary while it remains valid.

What it does not settle

The National Wetlands Inventory is a screening map, not a regulatory boundary. A parcel map, FEMA flood map, dry season visit, or listing description does not settle state or federal jurisdiction.

Check 4 / Shoreline and coast

Waterfront and coastal work

A local permit may be one part of the answer, not the whole answer.

Where to start

Name the water body and the work: dock, boatlift, seawall, fill, dredging, shoreline planting, mangrove trimming, dune work, repair, or new construction. Bring the survey, shoreline sketch, old permits, and photos.

What the file can settle

The path can include a city or county, DEP or a water management district, state-owned submerged land authorization, the U.S. Army Corps of Engineers, a delegated mangrove office, or DEP's Coastal Construction Control Line program.

What it does not settle

A waterfront listing, existing structure, contractor proposal, or local building permit does not by itself prove that a dock, seawall, trimming job, or beach project has every approval it needs.

Keep the documents honest

One useful record should not answer a different question.

Flood map
Shows flood-hazard mapping. It does not establish a wetland boundary, septic approval, shoreline ownership, or permission to build.
Parcel map
Helps identify the tax parcel. It is not a boundary survey and may not show easements, wells, tanks, wetlands, or the legal shoreline.
Home inspection
Can flag visible condition. It is not the septic permit file, a complete well-water test, a wetland determination, or a permit authorization.
Local building permit
Answers the local part of the job. State environmental, submerged-land, federal, mangrove, and coastal reviews can still be separate.
Listing field
Words such as sewer, well, waterfront, buildable, or dock-ready are clues to verify, not the deciding record.

Federal wetland check

The federal Section 404 path has changed recently.

As checked on July 14, 2026, the U.S. Army Corps of Engineers says it is currently the only entity in Florida that can issue federal Clean Water Act Section 404 permits after a court order paused Florida's assumed program. The Corps also says litigation could change that status. Use its current Florida update before relying on an old application, agency handout, or permit checklist.

FAQ

Florida land and water quick answers

Is a wetlands map enough to tell me where I can build?

No. The U.S. Fish and Wildlife Service says its Wetlands Mapper is not a regulatory boundary and should not be read as the presence, absence, or legal extent of regulated wetlands. Use it as an early clue. Ask the Florida permitting office and, when federal jurisdiction matters, the U.S. Army Corps of Engineers what determination fits the property and project.

Is a FEMA flood zone the same thing as a wetland?

No. A FEMA map addresses flood hazards for floodplain and insurance purposes. Wetland boundaries, drainage, surface-water permits, storm surge, evacuation zones, and insurance quotes answer different questions. One property can have several of those files.

Does Florida require a private-well test when a home is sold?

Florida Health says the state does not require well sampling simply because a private home is sold. That is not the same as saying testing is unnecessary. The contract or another party can still call for testing, and Florida Health recommends that owners test for bacteria and nitrate at least once a year.

Who has the septic permit for a Florida property?

The route depends on the county. DEP directly handles permitting in its transitioned Panhandle service area and Marion County, while county health departments continue to handle permitting and inspections elsewhere. Start with DEP's current permitting page because agency routing can change.

Does a city or county permit cover waterfront work?

Not always. A local building permit can be required while a separate state environmental authorization, state-owned submerged land approval, federal permit, mangrove review, or coastal construction permit also applies. Ask each office what its approval settles.

Can I build a dock because the property is advertised as waterfront?

Do not assume that. Water depth, navigation, shoreline and riparian lines, aquatic habitat, state-owned submerged land, old permits, local setbacks, federal jurisdiction, and the project design can all matter. Start with the address, survey, water body, and proposed dock.

Can I trim mangroves on my own property?

Some homeowner trimming can fit a Florida exemption, but the mangrove type, height, fringe depth, amount of trimming, prior work, location, and need for a professional mangrove trimmer can change the answer. DEP recommends contacting its district or delegated local office before work begins.

What should I check before buying vacant or rural land?

Start with the parcel and survey, legal access, zoning and planned use, water and sewer availability, septic and well paths, flood and drainage records, wetland clues, prior permits, and any waterfront or coastal limits. Price the unresolved work before the contract deadlines expire.

Official checks

Land and water property sources

Florida agencies handle septic, well construction, state wetlands, surface water, submerged lands, mangroves, and coastal construction. Florida Health covers private-well testing guidance. Federal wetlands and dredge-or-fill questions currently route through the U.S. Fish and Wildlife Service map and the U.S. Army Corps of Engineers.

Last reviewed: July 14, 2026

Use this carefully: Maps are screening tools. Agency routing, exemptions, and permit needs depend on the exact property and work and can change. Confirm the current path before excavation, fill, septic, well, shoreline, mangrove, dock, seawall, or coastal construction work begins.
