places differ so you need to look at the specific contract for an individual place.
some of the things to look at-does the resident get to remain in the unit they start in or as their needs change will they have to move to another type of unit (or shared room) with no guarantee of return to their original unit? one of the places my mom looked at would have made her move out of her entry level (no assistance needed) unit for even a temporary need of assistance. if she recovered she could have moved back but not guaranteed to the same unit (and we would have had to arrange for/pay for storage of her belongings b/c the assisted living units were much smaller). place she's at now, short of needing critical care nursing she can stay there the rest of her life. assistance is available in their own unit, and if the need occurs hospice can come in to provide services.
how much can monthly fees increase yearly? with some it can be huge b/c since it's considered 'board' vs. 'rent' it's not subject to the caps some states have on rent increases.
what is the cost if you require meals delivered to you during a period of illness? mom's place won't allow people in the dining room with certain symptoms active (esp. during flu season) so they will do like 3 days where they will deliver your meals to your room. after that it's a charge per meal delivery.
is any part of the fee to move in or 'deposit' refundable? one place we looked at zero was refundable, place she's at now it's refundable.
any charge for having a car? some places charge monthly fees if a resident has a car parked on the property.
any prohibitions on guests? some places don't allow overnite guests, some place a restriction on age/duration of visit (some places have special units set aside, fully furnished which they can rent nitely to visiting out of area family members, at rates much lower than area hotels. realy nice if you are visiting from a distance.).
if my mom were posting this response she'd add "ask them if they pester you"


that's because at the first place she lived, despite having a kitchenette (so cooking was allowed), if she did'nt come down for every freaking meal someone would be knocking at her door to "pester" her. place she's at now they reccognize she tends to eat in her room so they don't check on her unless they have'nt seen her take her newspaper off her front door (a friend's mom lives at a place that's automated-they figure if someone's not coming down for meals then they will be opening their fridge at least once over a period of so many hours. there's a sensor in the fridge and if it does'nt indiciate the doors been opened during the day AND the person no shows for meals-the staff checks in on them).
