DOB Regulations Query

Planning on changing from a 2-family triplex + garden apt to a 3-family, with two 1-bedroom apts on two top floors of a fairly narrow (16-foot-wide interior) 110-year-old brownstone. I’m unclear about width requirements for the apartment entry doors (i.e., entering from the common stair hallway). The doors are now 30 inches, and we plan on a 33-inch interior hallway. Will this be sufficient or must they be 34-inch doors and 36-inch interior hallways? Any enlightenment or direction to the code would be welcome.

Thanks for your input, MGA. Am applying for a new C of O, of course. Stairs would present quite an obstacle to someone in a wheelchair.

Thank you both. My pros say the same thing -- I was just hoping there was some possible other answer. Guess not...

Your information is correct that the corridors need to be 3'-0" min width, and the apartment doors 2'-10". Bathrooms and kitchens may be subject to ADA requirements if the building is deemed accessible to the disabled.

The conversion to 3-Family will definitely require a change to the Certificate of Occupancy, and the new layout will be subject to Multiple Dwelling Law, requiring each apt to have two means of egress to meet fire code. Installing sprinklers, in some instances, achieves code compliance, obviating the need for the second means of egress.
