"The Resistance HQ" is the main headquarters for The Resistance, located underneath the entrance of Isabella-2's house.
As the main place for the Resistance, it is also the place where the Firestorm Girls monitor the surroundings of the city in case there's any trouble, along with some other activities.
The headquarters return in "Tales from the Resistance: Back to the 2nd Dimension", although it has slightly fallen into disuse since the arrest of Doofenshmirtz-2.
