All sheds, whether they require a permit as described above or not, must meet the following zoning requirements:

Setback requirements:
Setback requirements vary by the size and shape of the lot, the zoning district, and whether it is a corner lot, interior lot, or double frontage lot.  Sheds are not permitted in the required front yard, side yard adjoining a street, or minimum side yard.  Sheds are allowed in a required rear yard but still must meet a minimum setback from the lot lines.  Please contact the Community Development Department at (847) 853-7550 or at for help determining what the required setbacks are for your property.  If possible, please have your plat of survey available.

Impervious surface coverage requirements: Sheds, as accessory structures, must meet the impervious surface coverage requirements, which are based on their location on a lot.
