The New York City Department of Buildings tweeted a photo of an illegal pool that was found on the rooftop of a Williamsburg building. The department said that the 480-square-foot pool, which was not built up to code, had the capacity to hold 60 tons of water.

The building on Flushing Avenue where the pool was found is not equipped to support that kind of weight, the DOB said, hence why it was ordered to be torn down.

The department said the pool was installed without proper permits or professional construction.

Footage from Wednesday afternoon showed the pool still up, but all the water had been drained.

1. oh my... that is beyond stupid

2. I know! So scary for the units below.

3. 120,000 pounds

4. Now THAT is some kind of entitlement right there.

Edit to add: Meanwhile on Fux Youz

DEMOCRATS ARE COMING FOR OUR NON-CODE POOLS. DEFUND MUNICIPALITY ZONING AND BUILDING REQUIREMENTS.

5. That could have been disastrous.

And by late afternoon the water would have been too hot to take a dip anyway.

6. Human beings are so goddamned stupid sometimes.

7. Whoever designed that building should get a pat on the back.

That amount of weight could easily have collapsed the building.

8. I suspect the roof was designed

to handle a large snow load which is probably what saved it.

10. Ooh, that's a very smart point.

11. Just trying to do a rough order of magnitude here...

Looking at the first result of a Google search, California standards (I know this pool is not in CA, I'm just trying to rough this out) for a commercial flat roof and a concentrated load is 300 pounds within an area of 2.5 ft x 2.5 ft, or stated differently, 300 pounds in a 6.25 sq ft area.

If the entire pool is considered to be a concentrated load:

The pool is 480 square feet divided by 6.25 square feet = 76.8 load bearing "sections".

The pool weighs 120,000 pounds.

120,000 pounds divided by 76.8 sections is almost 1,600 pounds of weight in a 2.5ft x 2.5 ft area.

1,600 pounds vs. 300 pounds using CA standards to rough it out.

I'm assuming the 300 pound standard is AFTER taking into account the weight of the building materials itself. Also, I have no idea what the NY standard is. But in any case, just roughing it out like this, this is WAYYYYY over weight.

Edit to add: I know this isn't the right way to calculate this. A concentrated load in a 480 sq ft area is calculated differently than a concentrated load in a 6.25 sq ft area because the weight is concentrated over a larger field. Just trying to get an idea of how bad this is.

12. yikes.. so five times the recommended load

13. Didn't know Bubba and friends moved to NYC. Hope the structure is still sound.
