When did the current ceiling height for sleeping room go into effect? Trying to legalize a space for sleeping.
I am reading that as you having a (blurry) permit, from 1963, indicating that they made an alteration to the basement space in 1963, converting a portion (or all) of the basement into a "room".
That raises a couple of questions regarding the "room" and its use as habitable space (i.e., 'living' space), and when it began being used as a sleeping room (bedroom). Habitable spaces which are not used for sleeping (are not bedrooms) have certain requirements, and sleeping room have additional requirements (due to the fact that one is "sleeping" and 'is not alert and ready' during an emergency situation).
Do you know when it was first used as a bedroom (sleeping room) ... preferably listed as such on one of the permits?
Permits and codes for the house as constructed in 1900 do not apply to work done later. Work done later needs to meet the permits in effect at the time the work is done. Thus, each permit for work done over time likely meets a revised code applicable when that work was done.
I did find this:

Words of caution: before you get to far into the ceiling heights ordinance, which I could not find online (you would need to go to them and search for a copy of the San francisco Housing Code 179-62 app. 7-13-62) ... make sure that room also complies with the Light, Ventilation, Sanitation requirements. Otherwise, you could very likely be opening a very large can of worms.

That can of worms could contain each of the following (note that Dwellings are Division 2, and a few of the items apply to Division 1, Division 2 Dwellings are exempt for those.
