My relatively new next-door tenants (5 years) use a high-frequency blender or Nutribullet at about7am almost every morning. Their kitchen is adjacent to my bedroom and the noise always wakes me up. Their apt was renovated, without any permits, about 12 years ago and might be the reason that noise travels to my apt.
I have written them notes re: NYC noise laws, have spoken to them, e-mailed the Managing Agent, followed up with phone calls, called 311 (to no avail) but they do not listen.
I keep a daily record of these problems.
They also provide shelter to "guests" who appear with luggage, almost at least once a week, although b&b is not allowed in this building.
Any advice would be appreciated by this sleepless tenant who has lived
in this building since 1971
