Affiliate Marketing Secrets

In female student housing either affiliated with campus or private and off-campus settings, is it reasonable for housing authorities, private landlords, or even residents to impose rules restricting male visitors from staying in the place of residence?
I ask this because I am a female student living off-campus. I had a roommate who backed out of a lease because she wanted her boyfriend to be able to sleep over.
For you as an American, is it strange or not so uncommon if people have visitor restrictions like these?
