All fences (except Snow Fences) require a zoning permit which are free to obtain.
A fence over 7 feet tall requires a building permit.
All fences shall be located entirely upon the property of the fence owner; however, the owner may enter into an agreement with adjoining neighbors to install on or across property lines. The written agreement, signed by all parties, must accompany the permit application. If adjoining property owners do not agree to such installation on or across their property line, the fence must be setback at least two (2) feet from that property line. No fence may be constructed within a public right-of-way.
Please reference City Code Section 4.60. Performance Standards, Subdivision 9.
