NYCHA's computerized Tenant Selection and Assignment Plan (TSAP) impartially chooses the next applicant for an apartment based on need priorities assigned to each applicant family and matches them to available vacancies as they arise. The TSAP system eliminates any and all interference from external entities and guarantees impartial selection of applicants for vacant apartments based strictly on the need priorities.

• The turnover rate in calendar year 2010 for NYCHA conventional public housing apartments was 2.97%.
• The vacancy rate of apartments available for occupancy was 0.60% as of March 1, 2011.
• Because of the varied need priorities that comprise a family’s TSAP profile and the low turnover and vacancy rates of apartments, it is virtually impossible to establish an average waiting time for a family to enter conventional public housing. Some applicants can be matched up with an available apartment in months, while others often have to wait years.
