I recently looked up this particular block of Geary Street on Google Maps to see what was there. Sadly it appears that this home was one of many torn down in the name of "urban renewal" in the 1960s. Geary Boulevard was expanded from a a two lane street to a major four lane thoroughfare, cutting right through the heart of San Francisco's Black community.

Fortunately the Western Addition house my great grandparents lived in at 2970 Pine Street is still standing! I visit it sometimes when I'm in the city. Here's a photo from my last visit:
