I am 23 and my sister is 17. Are we allowed to rent an apartment together?


Renting together is not allowed, even for a short amount of time, as this is considered permanently dwelling with your sister. However  you may visit her temporarily (e.g. coming from out of town to stay by her for several days or vice versa) but permanently is not allowed.

Poskim dispute the exact amount of days that is deemed temporary.

A brother and sister living by their parents, are allowed to dwell permanently in the same house, since others are present.
