Important Information About Local Ordinances

Issuance of an Onsite Sewage Treatment and Disposal System (OSTDS) permit by the State of Florida does not exempt the applicant from complying with all applicable local laws, ordinances, codes, and regulatory requirements. The applicant remains responsible for obtaining any required local approvals or permits.

Applicants are strongly encouraged to verify that the proposed system design meets local requirements before submitting an application to the State of Florida.

Application Information

Get started

Create a new application or look up an existing one using your AP Number.

Optional. Enter your AP Number and click Search to load your existing application. Leave blank to start a new application.

New Construction Permit: Required for installing an OSTDS on a property where no system currently exists.

Existing System Permit: Issued for evaluating or permitting an existing system when there is a change in property use, ownership, or system function.

Repair Permit: Needed to fix a failing or damaged OSTDS to restore proper function.

Modification Permit: Required for altering an existing system, such as expanding capacity, relocating components, or changing the system type.

Standard Abandonment Permit: Property owner, or agent, shall apply for a construction permit from the Department to abandon the existing septic tank. Department will evaluate the application and determine if an abandonment permit can be issued. Abandonment permit is issued on DEP 4016.

General Abandonment Permit (Fastest Method): The contractor who will perform the abandonment files a notice of intent to abandon the septic under a general permit as agent for the applicant. Department will issue the General Permit on DEP 4011 when the abandonment fee is paid.

For a conventional system, you can leave the subtype as Not Applicable.

Site Evaluation Requirement *

A site evaluation assesses soil, topography, and other conditions to determine the suitability of the property for OSTDS installation. Applicants may choose to have the Department of Environmental Protection (DEP) conduct the evaluation or hire a private site evaluator.

Important: If you choose to hire a private site evaluator, the evaluation must be completed before submitting this application. Additionally, the completed site evaluation must be uploaded as part of your application. Applications indicating the use of a private site evaluator without an attached site evaluation will be considered incomplete and cannot be processed.

If applicable, do you need DEP to set Mean Annual Flood Line (MAFL)?

Basin Management Action Plans (BMAPs)

Chapter 403.067, Florida Statutes, requires certain properties located within a Basin Management Action Plan (BMAP) area to install an Enhanced Nutrient-Reducing Onsite Sewage Treatment and Disposal System (OSTDS).

  • New systems on lots one acre or smaller within a BMAP area must meet enhanced nutrient-reduction requirements.
  • Some BMAP areas have additional requirements based on lot size.

Check if your property is located within a Basin Management Action Plan (BMAP) (opens in new window)

Variance Request

When standard OSTDS requirements cannot be met due to site-specific conditions, a variance allows your permit application to be reviewed and approved as an official exception, as long as public health and environmental protection are still ensured.
