i believe to be most accurate you have to first figure out and use the average grade of the building and the land surrounding it and measure the height to the top of a structure from there.

the average grade can of course vary a bit from the site itself and from sea level and it's immediate surroundings.

so how far from the building do you need to go to look around at the grade?

i dk.

i've read anywhere from a few feet from the building to the 'area' around it.

so given that confusion small differences should be expected depending on what is reported.

large differences no though.
