Here is a little more info I have dug up on HCAD. You can download all of the data from HCAD. The database files are tab separated text files. They are available here. http://pdata.hcad.org/download/index.html

The file that seems to have what we want is Real_acct.txt that is inside of the file Real_acct_owner.zip

In the interactive map on the main HCAD page, XV is the State Code to designate an exempt property. In the download, exempt property is listed as X0-X9. X1 is Governmental Exempt.

If someone has a place to host it, I have an excel file from the HCAD data of just the X1 properties minus US properties and properties with no street number (roads, monuments, etc). It is about 4.5 MB.

I have taken my Excel file, and uploaded the addresses to google maps. It seems like there may be some things missing, as I did not see a pin on the Hilton hotel by the GRB.

If anyone wants to poke around, the map is here.

Several years back, when the NRA show was at GRB, the NRA used the adjoining Hilton Hotel as its host hotel. I went there for a seminar during the convention and was greeted by a 30.06 sign.
I called NRA and asked why they would support a hotel that didn't support the Second Amendment. Got a bit of a runaround on that one.
