Updated: November 15, 2023

Beginning January 1, 2024, owners of buildings with parapets fronting the public right-of-way (a public street, avenue, sidewalk, roadway or any other public place or public way), regardless of height, are required to have an annual observation of the building’s parapet performed. See NYC Administrative Code §28-301.1.1 and Title 1 of the Rules of the City of New York §103-15.


  • detached one- or two-family homes
  • buildings with a fence or other barrier preventing access to the exterior wall.

Who Can Perform the Observation

A person competent to inspect parapets can perform the observation. This includes, but is not limited to a bricklayer, building superintendent, handyman, mason or a person in a similar construction-related trade, a NYS-licensed architect or engineer, a NYS-authorized building inspector or an inspector working for a NYS-authorized insurance company, or any other individual capable of identifying hazards on the parapet.

Report Requirements

The person performing the observation or the owner in consultation with the person performing the observation is required to prepare a report of the observation. Owners must maintain the observation reports for at least 6 years and make the reports available to DOB upon request. Review 1 RCNY §103-15 for more information about the observation and report requirements.

Hazardous or Unsafe Conditions

If hazardous or unsafe conditions are identified during the observation:

  • the person performing the observation must immediately notify DOB by calling 311 and emailing parapets@buildings.nyc.gov
  • the owner must immediately install public protection, such as erecting sidewalk sheds, fences, and safety netting to secure the safety of the public, and have the unsafe condition remedied. The public protection must remain in place until the unsafe condition is remedied.

– If a sidewalk shed needs to be installed, the applicant for the sidewalk shed filing in DOB NOW will answer YES to the new question on the Sidewalk Shed Scope of Work, Is the sidewalk shed related to the required periodic observation of the building’s parapet (1 RCNY §103-15)?

The unsafe conditions must be corrected within ninety (90) days from the notification to DOB.

Cahill Strategies Construction Solutions Guide to NYC Building Code Chapter 33 Revisions

Cahill Strategies has developed a detailed and documented guide to the most important revisions that New York construction professionals are likely to encounter every day. We were able to do this because Cahill Strategies has been involved instrumentally in the development of these codes.

The 100-page book is meticulously organized and can be used as a handy reference when many common issues arise. In each section, the specific revisions are highlighted, and the new information is presented in a clear and practical manner with further explanation on why the change is so important. All of this, reviewed and vetted by one of New York’s longest serving, former DOB professionals – Cahill Strategies’ Director of Construction Code & Safety, Bobby D’Alessio.
