Use Permits

The County requires business owners to obtain a Use permit before they can operate a new business or change the use of any business in unincorporated Lake County. (151.110) The County does not require business licenses, however, a business may be required to obtain other licenses in order to operate.

The County requires the Use permit to ensure that there will be adequate parking to serve the use (151.165(A)), the space meets current building and/or health code requirements for the use (171.035(D) or 173.04), there is adequate access to the site from a pubic roadway and (151.169(C)) and, if the property is served by Lake County Public Works sewer (53.05(C)(5)) and/or water (52.02(G)), to determine if the new business will be required to pay sewer or water permit fees.

When Do I need a Use Permit?



An Early Assistance (EA) meeting will be required so staff may determine if a Use permit will be required. EA meetings help identify project requirements and provide guidance to applicants, especially in cases involving complicated design issues or difficult projects, before the application is finalized. A summary of the EA meeting is provided to applicants and their design consultants to assist with design, layout, and/or calculation requirements for the Use permit.

In general, Use permits are required when the use (business) is located in unincorporated Lake County and either condition #1 or #2 is met:
  1. There is a change in use at the location.
    • The business will occupy a location that was previously occupied by a business that offered a different type of service than that which will be established in the space. Examples of changes in use include:
      • The conversion of an office space to a medical office space, an office space to a commercial retail space, a retail space to a restaurant, or a vacant space to a new business use.
    • A business proposes new or expanded uses at its current location. For example:
      • The redevelopment of an existing gas station to include a convenience store and car wash.
      • The expansion of a building.
  2. The use at the location does not change but the business that had occupied the space has been closed for over one year.

How Do I Apply?

So Now That I've Applied - What's Next?

  • If the space requires remodeling, you may be required to apply for a building alteration permit.
  • If the use includes selling food, you will have to obtain the appropriate permits from the Lake County Health Department (847-377-8020)
  • If the use includes selling liquor, you will be required to obtain a liquor license from the Liquor Commission. (847-377-2300)

How Much Will My Permit Cost?



Use permit fees are calculated at time of permit application and are based on the square footage of the building. Additional permits and fees, such as building or water, may also be required. The Early Assistance meeting fee will be credited towards the Use permit/Building permit fees at time of application of those permits.
