Market rate units; resident selection standards. At the time of initial occupancy of the assisted-living residence and when vacancies subsequently become available, occupancy in market rate units in such residence shall be offered on a priority basis to existing residents of the Village of Pleasantville, and such residents shall be given a reasonable amount of time in which to accept or decline such offer. The operator thereof shall at all times maintain a waiting list for occupancy in the assisted-living residence. All vacancies in such market rate units shall be filled by first offering occupancy to each Village of Pleasantville resident on such waiting list in sequential order until no names of interested Village of Pleasantville residents remain on such list, after which time occupancy in such market rate units may be offered to all other persons on a first-come, first-served basis. If a Pleasantville resident declines the first invitation for occupancy in a market rate unit in the assisted-living residence, such individual shall, nonetheless, if he or she so desires, remain on the waiting list for market rate units in the original numerical order and shall be again offered occupancy in a market rate unit in such residence on a priority basis when the next vacancy of such a unit becomes available. If a Pleasantville resident declines a second invitation for occupancy in a market rate unit in the assisted-living residence, such individual may, if he or she so desires, remain on the waiting list but shall be moved to the last position on such list, as it is then identified.
