We've included a map instead of a photo here for two reasons. First - and most important - you can't see the house from the street. We realize that's not going to stop some of you from trying, so here's the map.
In an odd bit of layout and street-naming, city planners created a gaggle of little streets branching off Carmelina in this area, all of them named Helena Drive with a sequential number: 1st Helena Drive, 2nd Helena Drive and so on. It's an odd way to do things that confuses many mapping systems. Between Sunset Boulevard on the north and San Vicente on the south, 18 of these little streets branch off from Carmelina. They're less than a block long and are basically long driveways between two houses facing Carmelina leading to two more behind them.
Monroe's house was at the end of 5th Helena Drive. The official address is 12305 5th Helena Drive, but your mapping system may have an easier time finding 333 Carmelina Avenue, which is at the end of 5th Helena Drive.
Given the ardent nature of Marilyn Monroe's fans, it's no wonder the previous owners put up a big wall that blocks any view of the house. Finally, they may have had enough. In July, 2010, the Huffington Post reported that the house was for sale for $3.6 million. See the official listing for a rare peek inside or go to Marilyn Monroe Memories to see a layout drawing
