The New York City Landmarks Preservation Commission on Tuesday approved an application by a Manhattan homeowner to build a gate at the front of what she called her “celebrity staircase.”

The staircase sits in front of 66 Perry Street, a brownstone in the West Village that was built in 1866 but gained its celebrity status more than a century later, when it became the exterior setting for Carrie Bradshaw’s apartment on the HBO show “Sex and the City.”
