What drives the price difference between a standard unit and an ADA unit?
I'm coordinating a weekend food festival in a city park, expecting about 500 people over two days. We'll have alcohol sales and multiple food vendors. The rental company quoted us for 10 standard units and one ADA-compliant unit, with service halfway through the event. The ADA unit costs more per week than a standard unit. I know it's larger and has grab bars and a ramp, but I need to explain the price difference to our budget committee beyond just 'it's accessible.' What factors drive the higher cost for an ADA unit? Is it the materials, the manufacturing volume, the delivery handling, or something else?
