Residential Building Code of NY State


R303.4 Stairway illumination.
All interior and exterior stairways shall be provided with a means to illuminate the stairs, including the landings and treads.Interior stairways shall be provided with an artificial light source located in the immediate vicinity of each landing of the stairway.

Exception: An artificial light source is not required at the top and bottom landing, provided an artificial light source is located directly over each stairway section.

R303.4.1 Light activation. The control for activiation of the required interior stairway lighting shall be accessible at the top and bottom of each stairway without traversing any steps. The illumination of exterior stairways shall be controlled from inside the dwelling unit.

Exception: Lights that are continuously illuminated or automatically controlled.


E3803.3 Storage or equipment spaces.
In attics, under-floor spaces, utility rooms and basements, at least one lighting outlet shall be installed where these spaces are used for storage or contain equipment requiring servicing.

This tells me that NY State electrical contractors and their men are required to install a minimum of one lighting outlet for the stairs and one lighting outlet for the basement.
