This is what I have known:
When the verb "stand" goes with an animate subject, it can be used in a progressive form.
(1) He IS STANDING aginst the tree trunk over there. (correct)
But when it goes with an inanimate subject, it can't be used in that form.
(2) The building IS STANDING in the middle of the city. (incorrect)

Is my understanding valid? Sometimes doubt creeps in.

Are the following sentences correct or incorrect?
(3) Go get me the ladder. It IS STANDING against the garage wall.
(4) Where is it gone? It WAS STANDING here a minute ago. (it = a mop)
(5) I saw a horror movie last night. My hair WAS STANDING on end.

And what about this?
If a reporter on a demolition site is reporting live, can he say like this?
(6) The building WAS STANDING right here a moment ago, but now it's completely gone.

I'd appreciate your expertise.
Hello Komountain

The progressive form of a tense denotes that the event the verb describes
was, is, or will be 'continuing'.

If the subject of the verb is unable to 'continue' in a significant sense, the
use of a progressive form will seem incongruous.

In your example 2, for instance, 'the building is standing' suggests that the building
is capable of a change of state. It started standing there a moment ago, and will
go to stand elsewhere at some time in the future. This is not our normal
experience of buildings (except in East European cartoons).

In example 6, however, we have the abnormal case: the demolition of a building.
In this context, 'continuation' has meaning. It was there a moment ago, but now
it's gone.

Ladders, mops, and hair, on the other hand, frequently change their states, and
so may be said to 'continue' in one position or another:

'The ladder's lying on the ground.'
'The mop was propping open the door a moment ago, but now it's gone.'
'Her hair was falling over her face and her nose was running.'

Many thanks, MrP.

So, whether animate or inanimate is not necessarily a clear divide.
Rather, whether changeable or non-changeable is a deciding factor.
Changeability may relate to context, too:

'The building is still standing' - after an earthquake. There was a possibility
of a change of state.
