For fans of “It’s Always Sunny in Philadelphia,” it’s not much of a secret that the exterior location for the famed Paddy’s Pub is actually in Los Angeles, not Philadelphia.  The building is in a warehouse area of L.A., which is heavily used by film and television productions, as the area can easily stand in for a variety of different cities.  While the address of the building is on Mateo street, you’ll actually want to turn the corner onto Palmetto Street, in order to see the side of the building that is used as Paddy’s Pub.  Just look for the unmistakable high curb.

LOCATION: 544 Mateo St, Los Angeles, CA 90013

The back exit of Paddy’s Pub, which is frequently seen on the show, is at an entirely separate building, located a couple miles away in downtown Los Angeles.

LOCATION: Alley on 11th St, just east of S Broadway  (approximately 115 W 11th St., Los Angeles, CA 90015)

The gang visits Dennis and Dee’s mom’s house in numerous episodes, which is also located in Los Angeles.  The same house can be seen in “Pretty In Pink,” where James Spader’s character throws a party.

LOCATION: 366 S June St, Los Angeles, CA 90020
