New York City Parks & Recreation Department allows group to gather on park grounds as long as the amount of people involved does not exceed twenty (20). This means that you can have your elopement ceremony in virtually any New York City public park space (including Central Park) as long as your wedding party (including the wedding officiant and photographer) does not exceed twenty (20) people. If there is more than twenty (20) people involved, you must obtain a "Special Event Permit". A permit is also good if you feel that the space that you would like to get married in is a popular one, having a permit allows you to reserve the spot. Here’s is the link on how to obtain that permit: NYC PARKS
Some things that aren't allowed in Central Park: Chairs, tents, tables, rugs, runners, throwing of rice, birdseed, flowers, confetti, or anything else that will affect the soil is not allowed in Central Park. There are exceptions to the use of chairs for those who cannot stand for long periods of time. Alcohol, candles, or amplified sound are not allowed. Acoustic music is permitted. Planning your own ceremony? One of the most popular locations, the Conservatory Garden, located at Fifth Avenue and 105th Street, which requires a permit for ceremonies and photography sessions. You can apply for your permit for the Conservatory Garden at the Central Park Conservancy by calling 212-360-2766 or you candownload the application online.For any other location in Central Park, you can download the application from the NYC Department of Parks & Recreation's website at the link above.
The maximum number of guests allowed for a ceremony in Central Park is 300. Each location has a specific guest limit. If you plan to have less than twenty (20) people at your wedding ceremony in a location outside of the Conservatory Garden, you are not required to purchase a permit. However, I highly recommend getting a permit to guarantee your space.
