Septic permitting and soil evaluation in Citrus and Hernando counties
Every compliant septic project in Citrus and Hernando counties runs through the same gate: a county health department construction permit built on a site and soil evaluation. The gate is not a formality. On the Springs Coast the evaluation is where karst sand, seasonal water tables, and Priority Focus Area rules turn into an actual system design, and the permit is what makes the finished work legal, insurable, and sellable with the house.
Who permits what, after the 2021 transfer
The state's Onsite Sewage Program moved from the Florida Department of Health to the Florida Department of Environmental Protection on July 1, 2021 under the Clean Waterways Act (Florida DEP program page). Citrus and Hernando, unlike some counties, kept local permitting at the county health department. Your application, evaluation, permit, and inspections all run through the county office, while DEP administers the program and the contractor registration statewide.
- Citrus County: DOH-Citrus Environmental Public Health, (352) 513-6100 (onsite sewage page). Current construction-permit fee: confirm with the office; we do not print a figure we could not verify.
- Hernando County: DOH-Hernando Environmental Health, Brooksville office, (352) 540-6800. Verified fees per the county permit instructions (form DH 4015): new-construction OSTDS permit $350.00, application and plan review $100.00, unmarked-lot fee $10.
The evaluation: where the design gets decided
The county's site and soil evaluation reads the parcel: soil texture by horizon, estimated seasonal high water table, setbacks from wells and surface water, and usable drainfield area. Springs Coast conditions show up directly in the findings. Fast-draining sand over limestone is common everywhere; high water tables dominate coastal parcels around Crystal River and Homosassa; and the Brooksville Ridge changes the picture again inland. The evaluation decides drainfield sizing and elevation, whether a mounded or engineered field is needed, and, together with the parcel's PFA status, whether the design must be enhanced nitrogen-reducing under the 2025 county notices. That last question and its zones are the mandate guide's territory, with the parcel lookup in the PFA self-check guide.
Permit before build, always
The compliant sequence is fixed: application, evaluation, permit issuance, construction, final inspection. Work built ahead of its permit risks tear-out orders and complicates any future sale, and no registered contractor with a reputation to protect proposes it. This sequence governs new installations, drainfield replacements, and permitted repairs alike; the county-by-county walkthrough with timelines is in the permit process guide.
Verifying the people who pull your permit
Two lookups protect you before any application is filed: the contractor's state registration in the Florida DEP search tools, and the permit history the county office holds for your parcel. The trust module below carries the links and phone numbers, plus the three questions worth asking. Five minutes of verification beats any promise printed on a truck.
Verify Your Septic Contractor's Florida Registration and Permits
Septic work in Florida is performed by a state-registered septic tank contractor. Registration runs under Chapter 489, Part III, Florida Statutes and has been administered by the Florida Department of Environmental Protection since the Onsite Sewage Program moved there from the Department of Health on July 1, 2021 under the Clean Waterways Act. The registered tier requires three years or 6,000 hours of experience, a state exam passed at 75 percent or better, and annual renewal each September 30; a septic business also needs its own Certificate of Authorization. Details: Florida DEP septic tank contractor registration.
The construction permit is separate from the contractor's registration. In Citrus and Hernando counties the county health department issues the onsite sewage construction permit and performs the site and soil evaluation: Florida Department of Health in Citrus County, Environmental Public Health, (352) 513-6100, and Florida Department of Health in Hernando County, Environmental Health, (352) 540-6800.
Where a parcel sits inside a spring Priority Focus Area, a repair or modification permit application filed on or after December 15, 2025 must include an enhanced nitrogen-reducing (ENR) system design, per the DOH-Citrus (2025-10-09) and DOH-Hernando (2025-10-10) notices. An ENR system is one approved for at least 65 percent total nitrogen reduction (or at least 50 percent before the drainfield), per section 381.0065, Florida Statutes.

Three questions worth asking any contractor
- What name is your Florida septic tank contractor registration under, and can I verify it in the DEP search?
- Will you pull the county health department construction permit before work starts, and is the permit fee in your written estimate?
- If my parcel is inside a Priority Focus Area, which ENR technology are you quoting, and what does its maintenance contract cost per year?
Springs Coast Septic is a matching service, holds no contractor registration, and performs no septic work. The registration and permit obligations described here belong to the independent licensed contractor you are matched with.
Frequently Asked Questions
- Who handles the permit paperwork?
- The independent state-registered septic tank contractor you are matched with, as part of the job. The county health department issues the permit and performs the site and soil evaluation; the contractor prepares the application, coordinates the evaluation, and builds only after issuance. Springs Coast Septic is a matching service and files nothing.
- Which office permits my parcel?
- In Citrus County, the Florida Department of Health in Citrus County, Environmental Public Health, (352) 513-6100. In Hernando County, the Florida Department of Health in Hernando County, Environmental Health, Brooksville office, (352) 540-6800. Both counties kept county health department permitting after the state program moved to DEP administration in 2021.
- What does the site and soil evaluation involve?
- A county evaluator examines the parcel and its soil profile: texture, seasonal high water table, and the area available for a drainfield. The findings set the system design, the drainfield size and elevation, and whether an engineered or nitrogen-reducing system is needed. It happens before the permit issues, which is why it happens before anything is built.
- What are the permit fees?
- Hernando County publishes verified figures in its permit instructions (form DH 4015): $350.00 for a new-construction OSTDS permit, $100.00 application and plan review, and a $10 unmarked-lot fee. Citrus County's current construction-permit fee was not published where we could verify it, so confirm the dollar amount with DOH-Citrus at (352) 513-6100 rather than trusting a number from anyone's website, including ours.
