Affordability requirements for conversion Varied by program and district What affordability requirements City of Yes layered onto conversions, if any
Overall effect Many well-located, physically suitable buildings were ineligible simply due to age or location Significantly broader eligibility — many buildings that could not convert before are now eligible
