The Arlington County Permit Office is CLOSED for in-person customer service. Many services are available online. Learn more.
This page compiles information about several projects commonly undertaken by homeowners. Each requires, or may require, a residential building permit. Some may require another permit as well. Because expiration criteria vary among permit types, be sure to know when your permit(s) expire. Also check to see if the person obtaining the permit(s) needs a Permit Authorization Affidavit.
Permit: Information coming soon.
Submission Requirements: See requirements for a residential deck.
Inspections: Once a building permit is approved, construction can proceed. You must schedule an inspection to ensure the safety and proper progress of the project.
Decks require three inspections that differ from those required for other residential projects.
- Footing inspection: footing holes are inspected prior to concrete placement. At the time of the footing inspection, you must have the ledger board attached to the existing house.
- Framing inspection: joists, beams, connections and mechanical attachments are inspected prior to placement of decking. In this inspection, lag screws, thru bolts and expansion anchors at the ledger board are inspected and turned to insure proper installation and tightening. Access to the inside of the house may be required.
- Final inspection: all remaining items are inspected.
Fees: See Fee Schedules
Fence/Retaining Wall or Wall
Permit: Fence/Retaining Wall or Wall.
A permit is required for any new or replacement fence, retaining wall, or outdoor wall that is not part of a larger project.
If the fence, retaining wall, or outdoor wall is part of a larger project (such as a new house, addition, or pool) then all information about it should be submitted with the building permit for that project.
Note about fence placement disputes: The Zoning Division does not enforce property lines. You should work with a Virginia-licensed land surveyor to verify them.
You must complete a fence/retaining wall or wall permit application in Permit Arlington. Click “Create” and select “Zoning Application.”

Fee schedules provide the range of fees charged for each type of application or activity related to land development in Arlington. Fees cover permitting, plan review, enforcement, inspection, service delivery, performance agreements, and conditions. There are separate fee schedules for the Inspection Services Division (ISD), Zoning Division, and Department of Environmental Services (DES). Some permits involve fees from more than one schedule.
Permits: Residential Building and Trade. Note: installing a communal pool (e.g., for a condominium complex) or water feature is a commercial project and requires Department of Human Services (DHS) review and inspections.
Submission Requirements: See requirements for a residential addition. If the pool project includes an accessory structure, such as a pool house/cabana, see requirements for a new house.
Inspections: See Building and Trade Inspections. Note that communal (commercial) pools also require health inspections, plan review and a license (see Water Recreation Facility Licenses).
