Relates to certain alterations based upon which room is being altered in a multiple dwelling.

Summary

S10199 is a broad revision of New York’s Multiple Dwelling Law and related New York City Administrative Code provisions governing alterations, conversions, and occupancy standards for multiple dwellings. The bill repeals several older provisions and updates many others to align with the New York City construction codes, especially for light, air, ventilation, room size, egress, heating, smoke detection, cellar access, and certificate-of-occupancy rules. It also revises how certain older buildings, converted dwellings, tenements, lofts, and joint living-work quarters for artists are regulated, with many references shifted from older code sections to the current city construction code framework. A major feature of the bill is that it changes the standards that apply when multiple dwellings are altered or converted, including rules for windows, courts, yards, basement use, bathroom and kitchen ventilation, and fire safety. It also modifies provisions for temporary certificates of occupancy and permanent occupancy of certain Class B hotel units for residential use, but only in limited circumstances tied to state-financed or publicly acquired affordable/supportive housing and subject to zoning, labor-notice, and affordability requirements. The bill further updates cross-references throughout the Multiple Dwelling Law so that the state statute tracks current city code terminology and standards. The bill’s impact on state law would be substantial because it rewrites multiple sections of the Multiple Dwelling Law and related city code provisions, while also repealing obsolete language. It would affect property owners, developers, architects, engineers, the Department of Buildings, local housing agencies, tenants, hotel workers, and residents of converted or altered buildings. In practice, it appears designed to modernize regulatory standards and reduce reliance on outdated statutory references, while preserving or clarifying safety and habitability requirements for older and converted buildings. There is no recorded committee transcript or vote history in the provided material, so there is no direct evidence of debate, support, or opposition from the legislative record supplied here. Based on the bill text alone, the measure appears technical and code-revising in nature, with an emphasis on updating standards rather than creating a new policy direction. The main points of possible contention would likely involve the balance between modernization and flexibility for owners versus maintaining strict safety, light, air, and occupancy protections for tenants and residents, especially in older buildings and conversions.

Impact

The bill would amend and repeal numerous provisions of the Multiple Dwelling Law and related New York City Administrative Code sections, replacing older cross-references with references to the New York City construction codes and revising substantive standards for alterations, conversions, occupancy, ventilation, egress, heating, and smoke detection. It would affect multiple dwellings, converted dwellings, tenements, lofts, garden-type maisonette projects, and certain hotel-to-residential conversions, as well as the agencies that review permits, certificates of occupancy, and code compliance.

Sentiment

No committee discussion or vote record was provided, so sentiment cannot be measured from legislative debate or roll call. From the text, the bill reads as a technical modernization measure with a regulatory and safety focus, suggesting a generally neutral-to-supportive posture among sponsors, while potentially drawing scrutiny from stakeholders concerned about building standards, tenant protections, and conversion rules.

Contention

Because no transcripts or votes are included, no specific member or stakeholder positions are documented. The most likely areas of contention are the bill’s relaxation or restructuring of some older statutory requirements, the shift to city construction code standards, the treatment of basement and converted spaces, and the conditions under which Class B hotel units may be used for permanent residence. Owners and developers may favor the flexibility and updated code references, while tenant advocates, labor representatives, and housing regulators may focus on whether the revised standards adequately protect safety, habitability, and affordability.
