Having a sub-standard lot or structure does not necessarily mean that you cannot make improvements thereto. Sub-standard lots that were created or platted prior to the zoning code being adopted by the respective municipality are also called legal “non-conforming lots”. Sub-standard structures that were built prior to the zoning code being adopted by the respective municipality are called legal “non-conforming structures”.
Typically, a legal non-conforming lot may not meet the lot frontage and/or lot area requirements required under the current zoning code, whereas a legal non-conforming structure may not meet the minimum size and/or location requirements specified under the current zoning code.
We suggest you speak directly with a Land Use Specialist regarding any work you may be considering to a non-conforming structure. A Land Use Specialist can be reached at (262) 857-1895.
