Dear Ms. Adams,
Thank you for posting your request on History Hub!
The information you received from the District Department of Consumer and Regulatory Affairs (DCRA) is incorrect. The National Archives does not have this information. Instead, the records you need are the “Construction building permits and technical drawings” (1949-1995) that are in the custody of the District of Columbia Archives. Please contact them via email at email@example.com.
We hope this is helpful. Best of luck with your research!
