Enacts the New York city arts space act

This bill creates tax benefits for buildings in New York City that provide affordable space for arts organizations. It directly affects eligible nonprofit arts groups (tax-exempt under IRS 501(c)(3)) and building owners who rent space to them. Key provisions require rent to stay at or below $20 per square foot annually, with higher tax exemptions for lower rents - up to 100% tax exemption for spaces rented at $10/sq ft or less, provided owners offer tenant improvements. The benefits apply for the duration of the lease, with specific rules to maintain affordability and meet city zoning requirements.
