The "general" New York exotics law states that you can't own "venomous reptiles as well as burmese pythons, reticulataed pythons, African rock pythons, green anacondas, yellow anacondas, Australian pythons, Indian pythons, Asiatic monitors, Nile monitors, white throat monitors, black throat monitors, crocodile monitors along with any hybrid of these reptiles and finally crocodilia." It doesn't say anything about Red Tail Boas (BCC or BCI), Carpets, or any sub-species of them, but the best way to know would be to check with your nearest wildlife department.
