New York City planned to shell out roughly $400 million total to renovate more than two dozen “ghost” preschool buildings that have been mysteriously sitting empty with no update from officials, The Post has learned.

Records show the city has already spent millions of taxpayer dollars on the 25-plus vacant sites, once designated to be built as pre-K or 3-K centers — though officials refused to reveal exactly how much has been poured into them so far.

The massive overall sum was earmarked to build out the 27 facilities, which were set to be completed between August 2020 and September 2025 as part of an expansion of the city’s free “3K for All” program under former Mayor Bill de Blasio.

But the buildings have remained empty to date — even as the city continues paying an unknown amount in rent to various private landlords who own the properties, The Post exclusively reported this week.

One of the planned preschools, in College Point, Queens, had the highest anticipated total price tag of more than $28 million, according to the Department of Education’s FY2020-24 capital plan report finalized last summer.

The city poured at least nearly $16 million in construction work for a “3K center fit out” of the building at 18-31 131st St. — including a “full interior renovation” and an outdoor play area — but it still hasn’t opened despite a September 2022 target completion date, records show.

Community organizers there said parents repeatedly asked the city for updates on the planned early childhood education center.

“There was much interest and frequent requests for more information by local families who thought of it as an easily accessible site,” reps for the group A Better College Point Civic Association lamented to The Post.

“As you know, it currently remains closed and empty – even though we could use the seats.”

At least $13.4 million in construction costs were shelled out on another expensive project in Ridgewood, Queens, that was designated as a 3-K center, building permits show.

The facility was slated to cost the city $20 million total and be completed in September 2023 — but never opened and is now being operated by Success Academy Charter Schools, records show.

The Post’s findings come as parents compete for limited city-run early childhood education seats close to home — leaving some with no other option than to turn to expensive private providers.

One city-run school on the Upper East Side set to open in 2024 had been sitting empty for so long that a Post investigation into the site prompted Mayor Zohran Mamdani to open the location just three weeks later.

The 27 costly yet still-unopened sites were part of a larger list of 47 “3K initiative projects” laid out in the agency’s capital plan report.

2022, out of a total $18 million earmarked for the location, permits show.

The site is still being “evaluated for potential use,” the DOE told The Post in a statement.

Last summer, a rep for the agency under then-Mayor Eric Adams, revealed to parents that there were no plans to open the school “based on current enrollment data and application trends in the surrounding area,” according to July 2025 emails obtained by The Post. 

The fate of another planned preschool at 1010 Third Ave. in Manhattan — which underwent more than $6.4 million in repairs, with a total anticipated price tag of $18.8 million — has similarly yet to be determined, the agency said.

“We’re working to create plans for all of those,” NYC Public Schools’ Deputy Chancellor for Early Childhood Education Simone Hawkins said during a City Council hearing Monday as she confirmed The Post’s reporting that the 27 centers remain unopened.

“Some sites were commissioned for development by prior administrations without corresponding funding allocated for services, decisions we are not in position to speak to,” a DOE spokesperson added to The Post after the hearing.

The agency representative insisted some vacant locations are “often still under active development,” waiting on permit approvals and other “operational requirements” to be met before programming can launch.

But the DOE wouldn’t say if any of the site would be opening in the next year, noting “plans will be shared publicly once timelines and approvals are confirmed.”

Brooklyn Council Member Lincoln Restler said that despite the previous Adams administration vowing there was limited demand for 3K seats and thousands of vacancies, some parents were only offered inaccessible spots located miles away.

“Our office receives hundreds of calls every year from parents who were only offered seats a long bus ride away, or declined to apply at all given limited offerings,” Restler told constituents in an email Tuesday.

“With a new mayor who is deeply committed to universal childcare, we are doing our best to add 3K seats in neighborhoods where they are most needed,” he said.

The DOE is “actively working to ensure that every family has access to quality 3-K and Pre-K programming within their community, as evidenced by the recent opening of a new Pre-K and 3-K site on the Upper East Side,” a spokesperson told The Post in a statement.

“As we review applications and identify areas where capacity is needed, we will continue to evaluate all vacant sites for the best, most responsible use, based on site readiness and community need.”
