Wow, this took a little bit of phone tag, but I finally found it. Probably about 1 year too late though.
The documents are kept at the Harrity Building. In order to get a copy you need to go to the 3rd floor, records and inspections. There you need to fill out a FOIA request. The lady said that this has to be done in person, but I just tried faxing it, so I guess I'll see what happens.
These links might help:
It was interesting, the closer I got to the information, the less friendly people were. The main info line guy was really nice.
Some other faqs. They are kept for 3 years, it might cost some $$ just to do the research. It might cost money to get them duplicated (this I can understand).
If this doesn't pan out, I guess I'll go ask the builder.
