Legal Question in Business Law in New York

Your landlord has the required Certificate of Occupancy, so that shouldn't be a problem. You're liable to your landlord for any damage you or your invitees (that's what your day rentals would be) do to the premises. You perhaps should run a background check on the "random people" to avoid having any liability for criminal activity on your premises; you don't want to be the guy who rents to Lee Harvey Oswald!!

As to any permits or licenses that NYC may require (and they may view this activity as operating a hotel), you should check with the City Clerk to determine what, if anything, is needed. You'll certainly need to let your landlord know of this unusual use of the premises and check your lease to be sure it's allowed.
