Plumbing/Gas Permit

The Arlington County Permit Office is  CLOSED for in-person customer service. Many services are available online. Learn more.

A plumbing/gas permit is required for adding, removing, or relocating fixtures, appliances, or piping for all plumbing and gas work.

Replacing fixtures and other elements on gas-fueled equipment requires a permit and inspections. On equipment not fueled by gas, however, replacement of fixtures, appliances, or piping of the same type, size, and location does not require a permit. Further exemptions from a permit can be found in §108.2 of the Building Code.

If you are unsure whether a permit is required, contact the Inspection Services Division by email or phone: 703-228-3800.

Submission Requirements

Plumbing/gas permit applications must be submitted online via ePlan.

  • Upon the replacement or new installation of any fuel-burning appliances or equipment in existing buildings, an inspection shall be conducted to ensure that the connected vent or chimney systems are (1) sized in accordance with the building code and (2) are clean and free of any obstruction or blockages, defects or deterioration and are in operable condition. You must provide the completed Chimney Vent Certification form upon completing inspections of such fuel-burning appliances or equipment.
  • Review ePlan online submission guidelines, which include document sizing and layout, standard file naming conventions, and file type requirements.
  • Based on the permit holder and applicant for your project, you may be required to upload a Permit Authorization Affidavit.
  • Applications that do not have an associated Building Permit may require plans or other supporting documents to be provided.
  • If there is an associated Building Permit, submit the plumbing or gas plans under the Building Permit.
  • Depending on the scope of the project, a fixture count may be required. Many permits that include plumbing fixtures require additional review from the Department of Environmental Services (DES) to validate the drainage fixture units.
  • When you apply, you must identify the type of building in your project. Some residential properties are considered commercial per the Building Code and therefore require a commercial permit. Determine whether your project is considered residential or commercial.
