Rental ads - Question

[cyclistca]

I've been checking out some rental ads in Vancouver, BC and I keep seeing n/p and n/s. I figure that n/p means no pets but what does the other one mean?

I thought n/s ment no sickos. Well that what I keep getting told when I try to look at a rental.

Thanks guys. I realized that after I posted. I was just concerned at the time because for some reason I thought it meant no singles .
