This might be a question for the old timers here - I have a 1926 semi -bungalow with a full basement and I am wondering if anybody knows how the frame of the house would be typically attached to the foundation. I had assumed it was bolted to the concrete through the sill plate like a modern house, but I have been informed that is a relatively new practice, and that it is probably "just sitting" on the foundation. Considering that the house has been through more than one significant earth quake, that is hard to imagine. Any one care to enlighten me as to how they did things back in the day?
I do design and drafting work on a lot of homes like your in my area, Orange CA. for clients that want to improve the existing or create an addition.
I have yet to come across an older home like yours that had any kind of anchor bolt from sill to foundation. I invariably have to show new anchors of some type on the new design. But not only new anchors but new shear transfer from sill to joist to walls to roof.
If they want it brought up to present day code.
