Single Room Occupancy (SRO) properties in New York City are typically used to provide housing for individuals who might not otherwise be able to afford or secure housing in the traditional rental market. Here are some of the common permissible uses for SROs in New York City:

1. Affordable Housing for Individuals: Many SROs are utilized as low-income housing for single adults, including those who may be transitioning from homelessness, those with low or fixed incomes, or those who require temporary housing.

2. Temporary or Transitional Housing: Some SROs may be used as temporary or transitional housing for individuals in various situations, such as those transitioning from rehabilitation centers or shelters.

3. Housing for Specific Populations: Certain SROs may be designated for specific populations, such as seniors or those with mental health challenges, where supportive services are also provided.

4. Hotel or Hostel Use: In some cases, SROs may be legally converted and operated as hotels or hostels, offering single-room accommodations for short-term visitors or tourists.

5. Supportive Housing with Services: SROs can also provide supportive housing where residents have access to on-site services, such as counseling, healthcare, and job training, tailored to meet the individual needs of the residents.

6. Student Housing: Some SROs may be used as student housing, particularly in areas close to colleges or universities, providing affordable living options for students.

These uses often come with various regulations, zoning laws, and housing codes that must be followed, and any deviation from permissible use can lead to legal challenges. Proper licensing, adherence to building codes, and compliance with rent regulation laws are typically required for the lawful operation of an SRO in New York City.
