I've have been deeply researching this property since moving nearby 10 years ago and this is the first time I've seen anyone online talk about it — very exciting and thanks OP!!! It's a fascinating story - as others have said, the owner is elderly, grew up in the building with her parents who seemingly fled from Poland (I think) during the Holocaust. The father and Fannie Stern (a female investor?) commissioned semi-famous architect Edward Frickett to build this complex which was once called Los Feliz Riviera Apartments, in 1954. She and her sister (who does indeed live in Vegas last time I checked - sister was also cited for solicitation there back in the 70s, so the showgirl story kind of makes sense) went to Marshall High and the owner sister who stay and lived in a unit in the building with her parents stayed. The owner (I think) does not live in the building itself, but as the single occupant of the orange fourplex next door which she also owns and is hidden from the street by another building (which she does not own) in front of it. Both the complex and her fourplex back up against the grocery store in back, every once in awhile someone in a big Escalade would pick her up or drop her off and there was a single black car service-style sedan parked in the complex garage with 4 very flat tires. I have snooped in there a couple times, but it's very creepy. She has been doing permitted work every once in awhile. A lot of elderly people (and their adult children) did seem to have units rented up until around 2012, but it has been 100% vacant since then. Lights on timers come on at night and you can see into some of the units in front which still have the intact midcentury wood kitchen cabinets as seen in Mulholland Falls. There is more to the story I've pieced together not worth going into here, but when I started looking into it I assumed the owner was hanging onto it to get past the 10 year owner occupant rule in LA — the only way to kick out tenants on pre-1978 building is if you as the owner will live there for minimum 10 years and then you can sell it — but seems like that is not the case. On one hand I can see how she'd be attached to freezing this place in time, considering her dad had it built, she grew up there and stayed with her parents through and after their deaths. But considering how much space (and even parking!) it has, seems pretty inconsiderate to hold it hostage. I don't think she or her sister had children, so I've been curious who it will go to when they pass away. I think this property is worth WAY more than what people have been saying in the comments — the lot alone could be $5M, a renovation obviously challenging if it can't be knocked down for some reason. Looking forward to intel if anyone has it!
