Yes, many popular state and city locations require permits in Colorado. These depend on the type of location and local regulations. Permits are used by city and government agencies to understand who will be filming in the area. The fees typically go toward the upkeep of the area. Often, hefty fines are enacted if you do not have the appropriate permits required for commercial photography. This applies to portrait, engagement, and wedding sessions. The venue you booked with for your event, however, will typically give you access to their facility as part of your package. Check with your sales manager and wedding coordinator to see if you have access for that day and/or other days, such as for a separate engagement or bridal session. Regardless of the type of location, I work with my clients to ensure compliance. Many times a certificate of insurance is required upon filing an application. The fees vary from free to several hundred dollars depending on the number of people in your group, number of hours, and the types of equipment that will be used.
