Stuff at the DC Archives

Okay there is a lot of history stuff from this weekend with the Washington Historical Conference and an email that went out regarding historic preservation that raised one of my eyebrows.
I was happy to stumble upon the DC Archives desk because the web presence of this part of the DC government is like nil. I had a researcher friend complain that he couldn’t find any information about hours, or contact info to save his life. It’s there, just not terribly easy to find like the Washingtonia collection or the Historical Society’s archive.
The DC Archives is at 1300 Naylor Court, NW (office 202 671 1105, fax 202 727 6076) and off the top of my head they have regular office hours. So they are right in Shaw, not too far from the Convention Center.
At the desk I got a list of the different series the archives has and here are a few highlights:

Department of Consumer and Regulatory Affairs:
Building/Construction/ Alternation Permits & Plans (1949-1995)

Department of Public Works:
Plans of Demolished Buildings (1900-1979)

Department of Housing and Community Development
Redevelopment Land Agency Records (1965-1976)
Shaw & H Street Building Survey Forms (1968-1972)
14th Street & Downtown Survey Forms (1968-1974)
Organizational Records, includes annual reports, history, etc (1934-1987)

Not on the list but I think it was confirmed that the records for a department that condemned buildings may be at the archives as well. I’m very interested in those.
