Take a look at the US Census Bureau's methodology page for the Building Permits Survey.[1] They statistically impute the numbers from a subset of 20,100 building permit issuing authorities, because they cannot collect all of the distinct authorities in the country with different data collection and storage policies.
Federal databases of postal addresses don't really have any reason to maintain data on the structures.
Some fire fighting authorities have building layouts for recently built buildings. They may all have their own methods for storing the data, and the coverage is confusing enough that the bodies and budget authorities responsible for fighting any long lasting wild fire frequently change.
Properties lines are usually recorded and maintained at the county level, and enforced by a county court and sheriff at their direction, but this too is not the case everywhere.
It is not outlandish to think that there are multiple federal databases that include all of the data on buildings in the US, whether at the Department of Defense, or at multiple agencies within the Department of Homeland Security. However, it seems common that only data collected as a side effect of the regular course of doing government business are released to the public, but data sets created as part of some form of security-related goals are not released to the public.
