    I am not sure about Baltimore, but there is no 2010 code.

    Bottom line is you most likely do need to ground rods for a new service.
    If this is a new home then a Ufer (concrete encased electrode) is all you need.

    I found these changes adopted :

    I found at :

    Electrical Inspections Main Page

    Does not appear that two rods are required.

    Look through it yourself to see if what you have is affected by their changes.
