Dear John: The New York City Administrative Code, title 3, 3-505 through 506, requires the displaying of house address numbers.

That question posed by another of your readers triggered a memory of mine. The above information I learned while attending the NYC Police Academy in 1965.

Stay well and live long. E.M.

Dear E.M.: Thanks for the information.

Having a house number on a building might help other people live longer since EMS, fire and police aren’t psychic when it comes to what building they are responding to.

So if you own a building, put the damn house number on it. It’s the least you can do.

And if you own one of those skyscrapers where you’d rather make the address on fancy Madison rather than East 48th Street even though your front door is on East 48th, too bad. Put the right building number on it.

And that’s all I have to say on the matter. Oh, one more thing. If someone happens to get hurt or die because emergency services can’t find the right address, I hope you and your insurance company get sued. So insurance companies should enforce this.

Now that’s all I have to say.
