Don’t be too shocked by the revelation in Sunday’s Post that real-estate reps accounted for 46 of the 136 lobbyist meetings with top Team de Blasio officials over just 54 workdays in March, April and May.

After all, Mayor Bill de Blasio’s open door to special interests (at least those that donate) is old news. It’s why city-lobbyist income skyrocketed from $62.7 million in 2013 (the last Bloomberg year) to a record $95 million in 2017.

Then, too, the mayor’s making some progress: Five years after taking office, he’s finally starting to make good on his 2013 vow of monthly public reports on such meetings.

Of course, the reporting still leaves a lot to be desired: It gives only vague descriptions of the subjects of the lobbyist sitdowns, such as “affordable housing” or “congestion” or “meet-and-greet.”

City Councilman Ritchie Torres (D-Bronx), head of the council’s Investigations Committee, called such labeling “opacity masquerading as transparency.” He also found “meet-and-greets” with developers five years into the de Blasio era to be “implausible.” (Funny: That sounds just like how Public Advocate Bill de Blasio used to complain about Mayor Mike Bloomberg.)

To be fair, City Hall needs to work with developers in order to deliver on de Blasio’s affordable-housing goals. And real-estate interests have no choice but to work with City Hall: It’s the only way to get much built in this town — and the reason why out-of-town companies rarely even try to break into the New York market.

Transparency is the key to avoiding the scandals that marked de Blasio’s first term, such as the notorious Rivington House flip.

Unfortunately, at the rate the mayor’s minions are moving, this City Hall won’t actually make it to full transparency until the next mayor’s already won election.
