Retaining wall contractor Fairfax Contractor is a Northern Virginia company that can build all types of retaining wall projects. In most Northern Virginia Counties, any retaining wall over 36 inches will require a building permit. Smaller walls such as plantar walls, garden bedding walls, and small retaining walls are exempt from the building permit process. If the retaining wall project you want to construct is over 36 inches, Fairfax Contractor can utilize two methods to secure the building permit. The first way is to utilize the Fairfax County detail for retaining walls, this method utilizes plans that the county has designed for 4-foot and 5-foot tall retaining walls. Only residential retaining walls fall under the typical retaining wall detail plans in Fairfax. The Fairfax County retaining wall detail plans located on the county website shows both a wood retaining wall detail and an engineered masonry detail. One other caveat is that these walls cannot be built with any problems with soil area, tiered, or used to support a driveway or other structure. The second method to construct a retaining wall over 36 inches in Northern Virginia requires engineered stamped plans for wood, segmental block, and masonry retaining walls. If you reside in the counties of Fairfax, Loudoun, Arlington, or Prince William County, you will be required to submit plans to the local municipalities to obtain a building permit if your wall exceeds 36 inches. Fairfax Contractor can produce the drawings needed to secure the proper building permit to build a legal, permitted retaining wall. Don’t be fooled by some unlicensed landscape company to build your retaining wall project. They may build your wall without a permit or, even worse, have you pull the permit in your name. The Virginia DPOR licenses Fairfax Contractor with a class A license this license is endorsed with the RBC stamp. Only contractors and companies with a valid contractor’s license in Virginia with an RBC (residential building contractor) stamp can pull the permit to build a legal retaining wall.
