In one of my opening paragraphs I need to descrive a sign for one of my ''house'' scenes.
Something similar to this but I need an opposite
An example of what I mean:

Open /Closed

Busy/ Available

Engaged/Free

I have one sign ready like this:

House Free Smoke

I am looking for the opposite

House Allowed Smoke?

This does not seem to be right.
Much help appreciated.
