Apply for a Permit
We strongly encourage patrons to apply online.
Please review the following information carefully as the application process has changed due to the ongoing COVID-19 pandemic.
- There are no COVID-19 related capacity restrictions for outdoor permitted events and picnics. Existing permit holders can increase their attendance up to the maximum capacity of their picnic grove by contacting the permits office and paying the difference in price (if any). The $5 change fee will not apply.
- Permit offices are open for walk-ins and appointments. Learn more and book an appointment
- Permit reservations are considered non-refundable. Refunds will only be issued in the event that state or local COVID-19 public health guidelines require the Forest Preserves to cancel your permit.
- There is an updated fee schedule for all 2023 events: Sample Permit Fees (PDF)
- Customers adding special use items to their picnic permit are encouraged to rent through a vendor from our Approved Vendor List to best meet the Forest Preserves’ insurance requirements. Insurance from vendors not currently on our Approved Vendor List will not be accepted. (Customers who own their own special use items are still required to provide proof of insurance.)
