What Hochul is doing, requiring all NY municipalities to provide for affordable housing, is something that has been in the NJ State constitution for decades (See Mt. Laurel case from ~1973). The only part of the policy that goes further in NY is a proposal to supersede local zoning and permit accessory dwelling units in all single-family zoning districts.

Of course, NJ's process is highly convoluted and messy, as the courts took over enforcement jurisdiction in 2015 from the Council on Affordable Housing, deciding that COAH and its methodology was defunct. Now affordable housing obligations are mostly enforced through litigation.

Jersey City was actually late to adopting this "round" (i.e. 2015-2025) of affordable housing mechanisms, only adopting its ordinances last summer. Given that it is by some metrics the most expensive city to rent in in the country, I wouldn't cite them as an exemplar.
