   Subd. 2.   Permit Required. Fences, retaining walls, and sound barriers as defined in subsection 1001.02 shall not be constructed without a building or administrative permit. The permit application shall be accompanied by a certificate of survey clearly describing the type, location, and method of anchoring the fence, retaining wall, or sound barrier. The owner shall be responsible for properly locating all property lines before construction of any fence.
