One overlooked lesson of this week’s horrid London fire is that public housing faces particular perils.

Yes, 24-story Grenfell Tower would be a NYCHA building if it were in New York City — low-income housing, not luxury apartments.

And, just as with NYCHA, a residents’ group had been screaming for years about problems that likely played a role in the fire that killed at least 17.

We don’t want to make too much of the comparison: The roles of national and local government are far different over there. And a management company was paid to take hands-on responsibility for Grenfell.

But the fact remains that all too many city public-housing residents know what it’s like to have years of complaints about “ineptitude and incompetence” go unheeded.

Not to mention repeated warnings of failure to comply with fire-safety standards.

The New York City Housing Authority is responsible for the safety of more than 400,000 residents. Pray that every NYCHA worker takes London’s tragedy to heart.
