House Policies
In consideration of our students and the State of Michigan clean air laws, Interlochen Center for the Arts (ICA) has adopted a smoke-free policy. Smoking is not permitted in buildings or on the ICA campus. We request the cooperation of all visitors, guests and Artists. Alcoholic beverages are strictly prohibited on the ICA campus. ICA reserves the right to have anyone removed from its campus that poses a threat to them or others. This will include but is not limited to anyone that is under the influence of alcohol or narcotics. Corson is a non-union venue. All staffing will be at the discretion of the ICA Director of Presentations and the Production Coordinator. ICA does not permit any action that would be violating any local fire codes.
This will include, but is not limited to the following:
- A total blackout of the seating area of the theatre is not allowed. The laws in the state of Michigan state that the side aisle lights must be at the level of 30% during any performance.
- Exit lights cannot be turned off or covered.
- All exits and aisles will remain free from any obstacle at all times.
The use of smoke machines and pyrotechnic equipment must be approved by the ICA technical personnel no latter than two weeks before the intended use.
In consideration to our patrons, no equipment will interfere with sight lines of the permanently installed seating. This includes speaker stacks and control consoles.
The use of any device that must be anchored into or alters the structure of the building is not permitted. This includes the use of a stage screws.
All equipment used in Corson must meet all UL, NEC, NFC, and OSHA standards for safety. The management reserves the right to deny the use of any equipment or set pieces that do not meet these standards.
Written certification of fireproofing for all "goods" ("soft" and otherwise) to be used on any stage must accompany such goods. Grand Traverse County Fire Marshall requires these documents to be presented on the day of the show into his own hand.
All parking will be at the discretion of ICA. Buses, trucks, and other vehicles will be parked as close as possible to the venue.
Where possible, ICA reserves the right to use ICA equipment for productions in Corson. All lighting, sound, and stage equipment that is a part of Corson Auditorium is to be handled by ICA personnel unless prior arrangements have been made.
Corson is open to performers 1 ½ hrs. prior to curtain time unless other arrangements have been made. The house is opened to the public ½ hr. prior to curtain time.
The ICA security staff provides all security. These persons are unarmed and wear an institution uniform.
