A Guide to Annual Parapet Observations in New York City
Effective January 1, 2024, the New York City Department of Buildings requires annual parapet observations for all buildings with parapets fronting a public right-of-way. This requirement was added under Section 28-301.1.1 of the NYC Administrative Code and applies to the vast majority of buildings in the five boroughs. The law was enacted in response to a series of incidents in which deteriorated parapets caused injuries and deaths. For property owners, compliance is not optional — and the consequences of a hazardous parapet go well beyond a violation notice.

Which Buildings Need an Annual Parapet Observation?
The requirement applies broadly — essentially any building in New York City that has a parapet facing a street, sidewalk, or other public right-of-way must have an annual observation. The two primary exemptions are detached one- and two-family homes and buildings where a fence or barrier prevents public access to the exterior wall below the parapet.
| Building Type | Requirement |
|---|---|
| All buildings with parapets fronting public right-of-way | Annual observation required — effective January 1, 2024 |
| Detached 1- and 2-family homes | Exempt from annual observation requirement |
| Buildings with fence or barrier blocking public access to exterior wall | Exempt — but barrier must prevent public access to the area below the parapet |
| Multi-family residential buildings | Required — applies regardless of building height |
| Commercial and mixed-use buildings | Required — applies to all commercial buildings with parapets fronting a public area |
What Must a NYC Parapet Observation Cover?
The annual parapet observation is not a visual inspection from the street or the roof edge. It requires a close-up inspection of the entire parapet — typically performed from a fire escape, roof-mounted anchor points, or another means of accessing the face of the parapet. The inspector must evaluate the structural condition, plumb, and stability of the parapet and all appurtenances attached to it.
| Element | What Inspector Checks |
|---|---|
| Full parapet face (close-up) | Inspect entire parapet from fire escape or roof — must be close enough to identify cracks, displacement, and material loss |
| Plumb | Verify parapet is plumb within 1/8 of its cross-sectional thickness — any greater deviation indicates potential structural instability |
| Masonry condition | Check for cracks, displacement, missing or loose bricks, missing or deteriorated mortar, and spalling |
| Coping stones | Inspect for loose, cracked, or missing coping stones — these sit at the top of the parapet and are common failure points |
| Appurtenances | Check that telecom equipment, railings, roof access railings, gooseneck ladders, and signs are stable and properly secured |
| Overall deterioration | Assess whether deterioration is localized or widespread and whether conditions are safe, safe with monitoring, or unsafe |
Who Can Perform a Parapet Observation in NYC?
Unlike some NYC inspection requirements that mandate a licensed professional engineer or architect, the parapet observation law casts a wider net. The observation can be performed by a bricklayer, building superintendent, handyman, mason, architect, engineer, New York State-authorized building inspector, or any person who is competent to identify parapet hazards. That said, the person performing the observation must be capable of recognizing the conditions that constitute a hazard. If the building has complex masonry, significant deterioration, or prior structural concerns, a licensed professional is strongly advisable.
What Happens If an Unsafe Parapet Condition Is Found?
The obligations are immediate and there is no grace period. Unsafe conditions must be reported to DOB right away and public protection installed to shield the sidewalk and public right-of-way below. Those steps come first — before any repair schedule is worked out.
When an observation reveals a hazardous or unsafe parapet condition, the property owner’s obligations are immediate. There is no grace period for reporting or for installing public protection. The following steps must be taken without delay.
| Step | Action | Timeline |
|---|---|---|
| 1. Notify DOB via 311 | Call 311 and report the unsafe parapet condition to the Department of Buildings | Immediately upon discovery |
| 2. Email DOB Parapet Team | Send written notice to parapets@buildings.nyc.gov describing the condition and location | Immediately upon discovery |
| 3. Install Public Protection | Erect a sidewalk shed or other approved public protection to protect pedestrians from falling material | Immediately — before the next business day |
| 4. Engage Licensed Professional | Retain a licensed engineer or architect to assess the full scope of repairs required | As soon as possible after protection is in place |
| 5. Complete Repairs | Perform required repairs under proper permits; file completion documentation with DOB | As directed by DOB and the licensed professional |
How Long Must Parapet Observation Reports Be Kept?
Observation reports must be kept on file for a minimum of six years and must be made available to DOB upon request. There is currently no requirement to proactively file reports with DOB — however, DOB can request them during an inspection or in response to a complaint, and failure to produce them is a violation in its own right. Keep the reports organized by property and year, with the name and qualification of the person who performed the observation noted in the record.

Frequently Asked Questions
What is the annual parapet observation requirement in NYC?
Effective January 1, 2024, Section 28-301.1.1 of the NYC Administrative Code requires property owners of buildings with parapets fronting a public right-of-way to have their parapets observed annually. The observation must include a close-up inspection of the full parapet face, a check of plumb within 1/8 of cross-sectional thickness, assessment of masonry and coping stone conditions, and verification that all appurtenances are stable. Reports must be retained for six years.
Who can perform a parapet observation?
The law allows a broad range of qualified individuals: bricklayers, building superintendents, handymen, masons, architects, engineers, NYS-authorized building inspectors, or any person deemed competent to identify parapet hazards. For buildings with significant deterioration, complex masonry construction, or prior structural concerns, retaining a licensed engineer or architect is recommended — their findings carry more weight if DOB scrutinizes the report.
What happens if my parapet is unsafe?
If the observation reveals a hazardous condition, you must notify DOB immediately by calling 311 and emailing parapets@buildings.nyc.gov. You must also install public protection — typically a sidewalk shed — immediately to protect pedestrians. Failure to act promptly exposes the property owner to significant liability and DOB enforcement action. After protection is in place, a licensed professional should assess the full scope of repairs needed.
Do I need to file the observation report with DOB?
No — the current requirement is to retain the report for six years and make it available to DOB upon request, not to file it proactively. However, this may change, and it is advisable to maintain thorough, organized records. If unsafe conditions were found and reported, the documentation of that notification and all subsequent actions should be kept indefinitely as a liability record.
