Street parking
Parking isn't really an issue. Mass street has plenty, the city also added a parking garage on the street East of Mass on the same block as the Granada.
In addition to the garage a block away, there are other lots and areas around downtown. These can be convenient, if you intend to eat somewhere prior to attending an event at the Granada, as there are lots of restaurants nearby.
There is a nearby public parking garage a block away.
Parking all over. Might need to walk a block or two.
