After leaving the cemetery Harold drives home in his hearse.
Then ... He approaches the entrance of his home along a road lined with eucalyptus trees.
... and Now, this, aptly named, is Eucalyptus Avenue in Hillsborough, an uber-affluent Bay Area suburb south of San Francisco, viewed from the junction with Redington Road (map). That particular grove of trees above has been taken out but there are still many remaining along this road.
Then ... The camera pans right, tracking Harold as he enters his family estate via a long driveway leading to his home. This is the Rosecourt estate at 815 Eucalyptus Avenue (map), built in 1913 for George T. Cameron, the publisher of the San Francisco Chronicle.
... and Now, the fine wrought-iron gate is still there but a new house has been built where the old driveway used to be.
The tree-lined driveway (on the left) leads right up to his home where he screeches noisily to a halt.
Then ... Harold's mom and friends stare in astonishment at the sight of the hearse. Behind them is her stately mansion.
... and Now, the 6 bed 7.5 bath Rosecourt mansion is largely unchanged today, but shortly after the movie was filmed the estate's 7 1/2 acres was subdivided into several lots and Rosecourt was readdressed 10 Stacey Court. The cobblestones are still there; they came from old San Francisco streets.
This recent aerial view shows how the original estate looks today. The subdivision added a new cul-de-sac, Stacey Court, off of Redington Road. RoseCourt Mansion became 10 Stacey Court and its original 815 Eucalyptus Avenue address was assumed by one of the new homes.
