* Extensive Damage: The earthquake caused widespread destruction, not just to homes but also businesses, infrastructure, and public buildings.
* Lack of Detailed Records: Records from that era were not as meticulous as they are today. The focus was on immediate rescue and relief efforts, not necessarily precise property damage counts.
* Fire Aftershocks: The earthquake triggered a massive fire that burned for three days, further destroying much of the city. This makes it difficult to separate earthquake damage from fire damage.
However, we can say:
* Massive Scale: The earthquake and subsequent fire destroyed an estimated 28,000 buildings in San Francisco. This number would include homes, but it doesn't isolate them.
* Significant Impact: It's safe to assume that a very large portion of the city's homes were either severely damaged or destroyed.
