Hi! I am a citizen volunteer with our city's neighborhood associations. We have had a lot of development in our town and something that would be beneficial to our neighborhood associations' as more development is pitched to us would be to know the height of the existing buildings in our town boundaries. As a neighborhood association, we don't have the funds to survey every building, and volunteers going around to every house with a laser measure isn't realistic or safe.

I found a publicly available LiDAR dataset and wrote a python program to calculate heights of existing buildings and homes on each property.

I want to check the accuracy of the height points given by my program/public LiDAR data before our association starts to utilize them as information. I'd like to find any known accurate height datapoints and check those against my dataset.

I'm looking for advice on where to find known accurate building heights, maybe from individual surveys done for existing development, tax assessor (?) etc; that I can then use to spot-check my created dataset. I can't rely on non-surveyed architect-reported (or builder reported) building heights because we have found that often the real building is not exact to the specs reported.

I searched the forum before posting, but I might not have the correct terminology regarding heights of buildings and datasets. So I apologize if this is a silly question. Any ideas are helpful, thank you!
