This is a 1910 home we inspected in Los Angeles. The owner provided original photos taken of the home and the original owners. The foundation of this home was all brick and mortar walls. The brick was surprisingly in decent shape. Additionally, it falls under Historic Preservation Law and the brick cannot be removed. The city actually helps with the preservation of the foundation and other historical elements by allowing homeowners to conduct an engineering report and give it to the city. This falls under what is called the Mills Act. You gotta love when a whole chunk of the foundation is just missing. I'm sure it's rodent heaven under there in the summer.
