The fees would apply only to for-profit programs or companies, of which there are now 36 that would see their rates rise, district officials said.
The prices were modeled on a scale used by Burbank Unified School District. There are hourly and daily fees that range from $20 an hour for classroom use, or $250 for the Glendale High School auditorium or $120 for the Toll Middle School auditorium.
Those fees would have been more than doubled in the current proposal discussed Tuesday.
"It's a huge jump," Chief Financial Officer Eva Lueck said. "There was some concern it may not be feasible for some groups."
District officials were without an estimate of the revenue that could be generated by new fees. Because the district earns so little income from these fees, there wasn't really much calculating the business staff could do, Lueck said.
"We really don't gather a lot of money from this area," she said. "Where we truly receive dollars from this area is when studios rent our facilities."
Board members instructed administrators to return with more modest fees that they could enact immediately.
"We have hard decisions to make as a board, even though we may not want to hurt some of these groups," school board President Greg Krikorian said. "If we're laying off teachers, we've got to look at ways to cut these expenses."
The fees apply to classrooms, cafeterias, multi-purpose rooms, gyms, dance rooms, lecture or music rooms, pools, stadiums and all middle and high school auditoriums, except at Roosevelt Middle and Daily High schools.
Nonprofits, government and civic groups serving Glendale Unified students and programs are exempt from the fees.
