What the real problem is with light pollution is the general city glow that lights up the sky and forms a light dome. Not so much a nearby room. My home observatory has a small house next to it that was being occupied. Made no difference to images. Just not direct light shining onto the scope area.
Light leaking out between curtains and windows that lights up the ground is more an issue when doing a nightscape but that it not what you usually do there.
I wouldn't sweat it too much.

All quite true Greg
Thing is, I like to do visual observing sometimes too, so while preventing sustained washes of light across the observatory is probably all that is required to prevent issues while I'm imaging inside a protective dome, making sure DOH!!!
moments dont occur while enjoying the dark sky environment outside, is the goal too
