Majority — Douglas J.
delivered the opinion of the Court.
In 1940 appellant constructed a four-story building on the Bowery in New York City and since that time has operated it as a lodging house. It was constructed so as to comply with all the laws applicable to such lodging houses and in force at that time. New York amended its Multiple Dwelling Law[1] in 1944,[2] providing, inter alia, that lodging houses “of non-fireproof construction existing prior to the enactment of this subdivision”[3] should comply with certain new requirements.[4] Among these was the installation of an automatic wet pipe sprinkler system. Appellant received notice to comply with the new requirements and thereupon instituted this suit in the New York courts for a declaratory judgment holding these provisions of the 1944 law unconstitutional and restraining their enforcement.

4 This followed a disastrous fire in an old lodging house in New York City in which there was a considerable loss of life.
Little need be said on the due process question. We are not concerned with the wisdom of this legislation or the need for it. Olsen v. Nebraska, 313 U. S. 236 , 246. Protection of the safety of persons is one of the traditional uses of the police power of the States. Experts may differ as to the most appropriate way of dealing with fire hazards in lodging houses. Appellant, indeed, says that its building,
Appellant’s claim of lack of equal protection is based on the following argument: The 1944 law applies only to
The difficulty is that appellant has not shown that there are in existence lodging houses of that category which will escape the law. The argument is based on an anticipation that there may come into existence a like or identical class of lodging houses which will be treated less harshly. But so long as that class is not in existence, no showing of lack of equal protection can possibly be made. For under those circumstances the burden which is on one who challenges the constitutionality of a law could not be satisfied: Metropolitan Casualty Insurance Co. v. Brownell, 294 U. S. 580 , 584. The legislature is entitled to hit the evil that exists. Patsone v. Pennsylvania, 232 U. S. 138 , 144; Bryant v. Zimmerman, 278 U. S. 63 ; Bain Peanut Co: v. Pinson, 282 U. S. 499 . It need not take account of new and hypothetical inequalities that may come into existence as time passes or as conditions change. So far as we know, the 1944 law may have been designed as a stop-gap measure to take care of a pressing need until more comprehensive legislation could be prepared. It is common knowledge that due to war conditions there has been little construction in this field in recent years. By the time new lodging houses appear they, too, may be placed under the 1944 law; or different legislation may be adopted to take care both of the old and the new on the basis of parity. Or stricter standards for new lodging houses may be adopted. In any such case the asserted discrimination would have turned out to be fanciful, not real. The point is that lack
