GLOSSARY

Oversell (Oversubscription)

Oversell is issuing more monthly parking credentials than stalls, priced on the fact that not all holders park at once. In a parking facility:

SELL MORE PERMITS THAN SPACES, CAREFULLY capacity 120% 100% ~88% permits sold physical spaces typical peak in use
Because not every permit holder parks at the same moment, an operator can sell more permits than spaces and still fit the peak. The discipline is watching the gap between what you sold and what actually shows: oversell too far and the peak spills over. Illustrative.
  • A 400-stall facility at an 85% peak show rate supports roughly 470 credentials at a 1.12x oversell.
  • The practice funds pricing headroom but requires occupancy data and a plan for the day everyone shows.

Considerations

  • Oversell ratios are use-specific; hospitals and courthouses behave differently than offices. Oversell is yield management applied to the monthly book.
