Generally speaking, any changes to Department-approved plans shall be approved by the plan review engineer who reviewed and issued the permit.
Sometimes, the changes can be handled over the counter on the same day it is brought in; other times, the changes may need to be resubmitted for further review with an additional plan review fee. In either case, it is always a good idea to first call the plan review engineer who issued the permit and ask for his/her help.
