Do I need a permit to repair a septic system in Virginia?

Yes, for a real repair. Virginia's sewage regulations bar anyone from building, expanding or modifying a septic system without a written permit from the health department, and a failing system needs a repair permit before work starts. There is no application fee for a repair permit. Pumping and some like-for-like part replacements count as maintenance unless a local ordinance says otherwise, and need no repair permit.

Free to ask. Local shops send quotes, and you pay only when you book one.

This is a job for a licensed pro in Virginia

This page explains what the work involves, the permits, what a licensed pro does and what drives the cost. It does not give step-by-step instructions, because this work needs a licence, a permit or both, and doing it wrong can injure someone. Before you hire, check the licence on Virginia's DPOR record.

The short answer

Yes, if the work is a repair. Under Virginia's Sewage Handling and Disposal Regulations: "No person or owner shall construct, operate, expand or modify a sewage disposal or handling system without a written permit from the commissioner."[1] In practice that permit comes from your local health department, and it has to be issued before anyone starts digging. Routine maintenance such as pumping does not need one. The application fee for a repair permit is waived by regulation, but the design that must go with it is not free.

When a system has legally failed

The regulations set out what counts as failure. Raw or partly treated sewage on the ground, in nearby ditches or waterways, or exposed to insects, animals or people is prima facie evidence that a system has failed.[2] They add: "Pollution of the groundwater or backup of sewage into plumbing fixtures may also indicate system failure."[2]

When the health department documents a failure, it issues the owner a Notice of Alleged Violation (NOAV) that sets out what must be done and the time allowed for the design and repair.[3] The work needs a repair permit, and in most cases a private onsite soil evaluator, sometimes with an engineer, studies the site and soils and designs the repair.[3] The local health department approves the repair application, and the permit has to be issued before work starts.[3]

Repair or maintenance?

The line between the two decides whether you need a permit. The Virginia Department of Health puts it this way: "A properly licensed service provider can make simple improvements to the system, provided those improvements fit into VDH's definition of maintenance."[4] Bigger improvements need a repair designed by a licensed designer and a construction permit from the local health department before the work is done.[4]

Virginia Cooperative Extension treats replacing the distribution box, or piping outside the drainfield area, as maintenance rather than repair.[3] The onsite licensing board's definition, last amended effective December 17, 2025, says much the same. Unless a local ordinance provides otherwise, maintenance covers adjustments to equipment, periodic pumping of the tanks or cleaning of the building sewer, and "in-kind replacement of normal wear and tear parts that do not require a construction permit", such as pumps, sewer lines, conveyance lines, distribution boxes and header lines.[6] The same definition says maintenance never includes "replacement of tanks, drainfield piping, subsurface drainfields, or work requiring a construction permit and a licensed onsite sewage system installer".[6]

An older definition in the Board of Health's regulations, 12VAC5-613-10 as amended in 2017, draws the line differently: "Maintenance shall not include replacement of tanks, drainfield piping, and distribution boxes or work requiring a construction permit and an installer."[5] Because the two definitions disagree on distribution boxes and a local ordinance can change the board's, call the local health department before the work is booked and ask how your job is classed.

Pumping has its own rule: anyone who pumps out a septic tank, or contracts to, and hauls the contents away by vehicle must hold a written sewage handling permit from the state,[1] so ask the company for it.

Who prepares the application

You cannot simply ask the health department to design the fix. Since August 11, 2019, every application for an onsite sewage system or private well has to come with supporting work from a private sector consultant licensed through the Department of Professional and Occupational Regulation (DPOR).[7] Health department staff do the evaluation and design only for owners who submit a petition and meet its income or hardship rules.[7] In most cases the consultant is a private onsite soil evaluator, sometimes working with an engineer.[3]

What the permit costs

The state regulation is clear: "Any person applying for a permit to repair an onsite sewage disposal system or alternative discharging system shall not be charged a fee for filing the application."[8]

Local pages do not always say the same. On its website, the New River Health District, which covers Floyd, Giles, Montgomery and Pulaski counties and Radford, says it charges fees for construction permits for onsite sewage disposal systems, including repairs.[9] The regulation governs, and a repair of a failing system should carry no application fee, but ask the office what applies to your case before you file. The New River Health District also says owners with adjusted gross income below the federal poverty guidelines pay no application fees.[9] Our guide to drain field repair costs covers the rest of the bill.

The repair waiver, and what it means when you sell

Repairs do not always have to meet every current standard. Under Va. Code § 32.1-164.1:1, the owner of a failing system serving one to four dwelling units may request a waiver from a requirement for treatment beyond what the existing system provided when working properly, or from a new requirement for pressure dosing.[10] The statute adds: "The Commissioner shall grant any request for such waiver, unless he finds that the system was installed illegally without a permit."[10]

There is a catch. The waiver is recorded in the land records and becomes void when the property is sold, except for transfers the law specifically allows, such as court-ordered and foreclosure transfers, transfers in settling an estate, and transfers between spouses in a divorce.[10][4] The seller must give the buyer a written disclosure before a purchase contract is accepted.[10] After an ordinary sale, the new owner has to bring the system up to the full requirements, including the added treatment or pressure dosing.[10][4] If you expect to sell within a few years, ask your designer to price both options.

Timing

A septic tank permit is valid for 18 months from the day it is issued, unless the soil or site conditions change substantially,[10] so there is time to schedule an installer, but a failing system should not wait. After a flood or hurricane, give saturated ground time to drain. If the system is damaged or stays sluggish, the next step is an application to the local health department to repair it.[12]

When to call a licensed pro

Call a licensed onsite soil evaluator or engineer as soon as sewage surfaces, backs up, or the health department sends a notice. Virginia law is plain about who may do the work: "No person shall operate a waterworks or wastewater works, perform the duties of an onsite soil evaluator, or install or operate an alternative onsite sewage system, without a valid license."[11] Before you sign, check the licence on DPOR, and read what a drain field repair involves.

Common questions

Does pumping my septic tank need a permit?
Not a repair permit. Pumping is maintenance. The company that hauls the waste needs its own sewage handling permit from the state, so ask whether it has one. Pumping more often than usual is a sign to have the system checked.
How much is a septic repair permit in Virginia?
Nothing for the application: under the state fee regulation, filing for a repair permit for an onsite sewage system costs nothing. You still pay the licensed private consultant who evaluates the site and designs the repair, which every application now needs.
Who applies for the permit, me or the contractor?
The owner is responsible for the repair, and the application goes to the local health department with the private evaluator's or engineer's design. Ask the designer whether they prepare and file the package for you, and confirm in writing who files and who meets the inspector.
Can the health department make me install a more expensive system?
For one to four homes, Va. Code § 32.1-164.1:1 lets the owner of a failing system ask for a waiver from added treatment or new pressure dosing requirements, and the waiver must be granted unless the system was installed illegally without a permit. It is recorded in the land records and becomes void when the property is sold, apart from transfers the law exempts, such as foreclosures, estate transfers and divorce settlements.
How long is a septic permit good for?
Under Va. Code § 32.1-164.1:1, a septic tank permit is good for 18 months from issue unless the soil or site conditions change substantially, with a possible extension when building has started. For a failing system, plan to build the repair well before then.
What if my septic system was damaged in a storm?
Use as little water as you can and wait to see whether the soil drains. If the system has been damaged or stays sluggish, VDH says you will need to apply to the local health department to repair it, or call your licensed operator if it is an alternative system.
