Can a Building permit expire?

[lquade]

i didn't notice the engineer put a galvanized water tank on my permit for my house. never wanted one. so when i went to get the permit for my gunite water tank i had to first buy a demo permit for a tank that never existed. the inspector had to come out and verify the demolition and then i got a new permit for the real water tank... just time and money that the county loves to do...
