Tents and Other Membrane Structures
Utilize the resources on this page to apply for a Tent and Membrane Structure Permit
Tents and Other Membrane Structures are temporary, and so, the County’s building and fire codes allow placement for only 180 days within a 12-month period. To address these codes, Arlington County has developed the following policy:
• Structures less than 120 square feet are allowed through the TOSA process and may remain in place for the duration of the TOSA.
• Tents larger than 900 square feet, tents on rooftops, and structures more than 120 square feet require permits. Schedule a code consultation with ISD to discuss.
• For temporary tents larger than 120 square feet but less than 900 square feet:
▪ Businesses may apply through the Fire Prevention Office for a inspection/permit for the placement of a new temporary tent. Businesses must insure they meet the requirements of the Virginia Statewide Fire Prevention Code, Chapter 31 Tents and Other Membrane Structure. (see provided check sheet(PDF, 691KB) for assistance)
▪ If approved, businesses must wait 180 days (6 months) after the removal of the existing tent to install a new, approved temporary tent.
Please contact the Fire Prevention Office for consultation and to request an inspection
