I am searching for building/property data which include building height, building area, lot size, and building type classifications(preferably as complete as possible). I am working on an Earthquake Model for highly urbanized locations, especially those around fault lines. I would greatly appreciate the help. Thank you!

The only thing that even comes close AFAIK is the national cadastre.

Your link only covers the data model. Do you have a link to data? –  Regan Sarwas Dec 17 '10 at 2:58

Maybe a possible approach few cities have 3d models for many of their buildings in google earth. Perhaps you can check whether these can be downloaded and used in another tool?

CityGML is an approach to provide such a data in a more standardized way, but I don't think they have much data available. http://www.citygmlwiki.org/index.php/Main_Page

There was a previous question just regarding building data. In the USA, Massachusetts has both building data and lot outlines (I'm not sure about building type classifications).

I would also explore OpenStreetMap as perhaps this data exists for some countries.

Yes, in OpenStreetMap (some) buildings are tagged as such. See also this new Wiki page: grass.osgeo.org/wiki/Extrude_2D_polygons_to_3D ("Creating a 3D city model" from OpenStreetMap). –  markusN Oct 23 '11 at 9:53
