When were certifications filed on Class C violations at 1858 Caton Avenue, Brooklyn?

Since September 29, 2023, certifications were filed on 43 Class C violations, all 43 by the original certify-by date. A certification is the filing, dated when it was made, not HPD's acceptance of it. It is compared with the original certify-by date on the notice.
