Residential Additions & Expansions


You want to construct an addition to your residence including but not limited to a full residential addition, attached garage addition, screen porch addition, covered porch addition or eave extension.


The permitting process for residential additions and expansions is designed to ensure compliance with the Kenosha County General Zoning and Shoreland / Floodplain Zoning Ordinance Information. A zoning permit must be issued prior to receiving a building permit from your local town building inspector.


It is recommended that you meet with county development staff prior to submitting your zoning permit application for a residential addition or expansion to discuss the basics of your application, such as sanitation, building design and building setback requirements.

You must submit your zoning permit application, stake-out survey or site plan, floor plan layout(s) and architectural drawings along with the appropriate fee(s) based upon the Kenosha County Department of Planning and Development Fee Schedule.

Ordinance Requirements

Ordinance requirements vary for addition and expansions, depending on the zoning district classification of the property and the type and proximity of any environmental assets.


You can anticipate that the review of your zoning permit application will take approximately seven to ten working days dependent on whether the application documents contain all pertinent information in relationship to the requirements for your proposal.
