In orthodox churches and especially monasteries it is essentially mandatory to give you a place to sleep while doing some work for them until you get back on your feet.
It also used to be customary for people in villages and towns to always accept a traveler for the night, but not anymore, unfortunately.
Orthodox churches do not feel obligated to provide lodging. Sure, some parishes will let the homeless bed down at night, but this is a small minority, and in general Orthodox parish priests would prefer you take advantage of homeless shelters instead of expecting lodging from a parish church.
Orthodox monasteries larger than a skete are obliged to provide hospitality, but the prevailing interpretation is that this hospitality is limited to three days, and then it is the abbot's call to let you stay further or ask you to leave.
