‘Poor doors’ to appear on ‘Blue Bloods’

It’s an open-and-shut case.

N👍ew York’s notorious “poor door” is getting t❀he TV treatment — ­appearing in a crime scene in an ­upcoming episode of the CBS police drama “Blue Bloods.”

Extell and other developers are making headlines for building luxury towers with separate entrances for poorer, subsidized tenants. Now television is tackling the controversy.

CBꦚS last week announced the ಌ“Poor Door” episode, where detectives played by Donnie Wahlberg (right) and Marisa Ramirez probe a murder.

“Danny and Baez investigate a murder of a lower-income resident in a luxury building where 20 percent of the units are made♓ affordable for lower-income housing,” CBS announced.

“Poor doors” are a result of a city program that pಞermits developers to build bigger properties in exchange for providing on- or off-site affordable housing.

The show airs Feb. 6.
