Please note: Definitions in this glossary are stated in plain language for easier understanding. Please refer to the McHenry County Zoning Ordinance for more precise definitions, where applicable
Adjoining property owner
The owner of a property that touches the subject parcel. This includes property that would touch if property lines were extended across a public road, street, alley, or any other public way.
This is a document which attests that all noticing requirements of the Unified Development Ordinance have been met (i.e. certified letters have been sent to adjoining property owners and interested official bodies within the proper time frame). A memorandum or affidavit of mailing will be prepared and filed by County staff to confirm that the noticing has met all requirements.
Affidavit of posting
This is a document in which a petitioner attests that all posting requirements of the Unified Development Ordinance have been met (i.e. a zoning sign was placed on the subject parcel along the principal road frontage within the proper time frame).
This term is typically used to describe whether or not a parcel can be improved with a residence. The Department of Planning and Development can examine a parcel’s history to determine if it meets the legal requirements of the Unified Development Ordinance and the State Plat Act. This determination of buildability, however, does not address whether or not soils on the parcel can support a septic system, if a well can be placed on the parcel, or if it is in a flood hazard area or wetland. So, while a parcel can posses the legal rights to be “buildable,” there may still be site-specific factors which make constructing a residence impossible.
A U.S. Post Office service whereby, for a special fee, a letter’s addressor receives a receipt stamped with the date of the mailing, the letter must be signed by the addressee before final delivery, and the addressee-signed card is returned to the addressor as proof of receipt.

See the McHenry County 2030 Comprehensive Plan.
A use which, because of its unique characteristics, cannot be classified in any particular zoning district. Conditional use requests are heard by the Zoning Board of Appeals before being put forth to the County Board for the final vote. Restrictions are typically placed on the use (in the form of conditions) that limit potential harmful effects of such a use in a given location.

McHenry County Zoning Ordinance
This 2000 McHenry County Zoning Ordinance was replaced by the Unified Development Ordinance, effective 2014 October 22nd.
Non-Conforming Uses, Lots, and Structures
Non-Conformities (also called "grandfathered" uses) are defined in the Zoning Ordinance. Generally speaking, non-conforming lots remain buildable (insofar as zoning regulations are concerned – subject to bulk development standards, such as setbacks and height limits); non-conforming structures can be maintained, but limits to re-building may apply, and non-conforming uses may continue if they have not been abandoned for a specified period. For details, see the County Code. For rules regarding the ability to rebuild non-conforming structures with Substantial Damage, see the 50% Rule form and instructions. Please be aware that the Stormwater Management and Public Health Ordinances also affect ability to build or re-build.
The Natural Resources Inventory (NRI) form must be completed and submitted to the McHenry-Lake County Soil and Water Conservation District as a part of any zoning petition application. That agency will then provide the Zoning Board of Appeals (ZBA) or the McHenry County Hearing Officer (MCHO) with a report or letter containing its findings.

The purpose of a variation is to overcome a hardship caused by an over-generalized zoning rule as applied to a specific property. For example, a particular property may be too narrow in one area, or perhaps the topography or septic layout is a hindrance to building placement. Filing of zoning application and County Board approval is necessary. (See also "Administrative Variation" above for minor variations of 10 percent or less. )
A meeting of the Zoning Board of Appeals (ZBA) wherein a vote is taken to recommend or deny a zoning petition.
