These structures are considered accessory buildings. The City of Irving requires that all “accessory buildings, whether permanent or temporary, shall be securely affixed to the ground in a manner that will resist movement from storms or vandalism. All accessory buildings, whether permanent or temporary, shall meet the setback requirements.”
The City of Irving does not require a building permit for an accessory building that is 6 feet in any dimension; however, in those instances the buildings still need to meet the setback requirements of the City of Irving Zoning Ordinance.
For accessory buildings of more than 6 feet in any dimension, a building permit is required. The City’s building inspectors will inspect the structure to ensure that it is securely anchored and installed in accordance with manufacturer specifications.
