N.Y.C. Charter § 398: Section 398. Ex parte administrative warrants.

If entry to a location or premises to be inspected pursuant to an agency's powers and duties is not gained on consent, or if circumstances call for entry without prior notice, the commissioner of such agency, or his or her authorized representative, may request the corporation counsel to make an application, ex parte, in any court of competent jurisdiction for an order directing the entry and inspection of such premises or location and, in accordance with applicable law, to abate any nuisance thereon. Nothing in this section shall be construed to limit, abridge, affect or amend the power of an agency under law, including state, local or case law, to enter and inspect any location or premises or abate any nuisance thereon, either with or without a warrant, to carry out any of its functions, powers and duties.
