Will keep you posted - have not been provided with the drawings yet (the review was part of a due-diligence process for someone purchasing a home). Not even sure if the client is buying the home anymore.
I did not see anything method of later supported - I have requested the drawings, though my initial recommendation was that tension ties would have to be installed. Got flack from the owner about "...the town approved the installation..." (how many times have we heard that one? :)).
Do hurricane clips replace the need for tension ties when rafters rest on top of exterior wall top plates and attic floor joists run perpendicular to the rafters? http://files.engineering.com/getfile.aspx?folder=e28f4cb0-7edc-44eb-a7c5-442c5e8e18c9&file=DSCF8810.JPG
