Key statistics
Key takeaways
Facade inspection is a mature, expensive regulatory regime across US cities. The laws were written after people died from falling debris, and the filing data now shows a rising share of unsafe buildings, huge repair bills, and years of sidewalk sheds while owners defer the work.
In NYC's latest FISP cycle, 13.3% of facade filings were rated unsafe, up from under 1% two decades ago.
More than a dozen US cities now require periodic facade inspections.
More than 16,000 NYC buildings are covered by FISP, up from about 12,500 in 2007.
A NYC facade inspection costs $5,000 to $25,000 or more for the inspector alone.
NYC facade repairs typically run $50,000 to $500,000 or more.
NYC had roughly 9,000 sidewalk sheds spanning nearly 400 miles of sidewalk.
NYC's facade law dates to 1980, after a student was killed by falling masonry.
How we built this report
Every figure below was compiled in September 2026 from named public sources and verified against the original before publishing.
- Compiled from primary sources
City ordinance summaries and code sections, New York City Mayor's Office announcements, an analysis of NYC Open Data facade filings, reporting from Gothamist and Habitat Magazine, and engineering-firm compliance bulletins.
- Only explicitly stated figures
We include only numbers a named source states directly, and attribute each inline at the point it appears, with the source's root domain.
- Numbered laws kept precise
Statutes and code sections are cited exactly (Local Law 11, Chicago Municipal Code 14A-6-603.2, San Francisco Existing Building Code Chapter 5F). Cost ranges come from vendor cost guides and are labeled as such.
- Independent review
Written by one co-founder, reviewed by the other before publishing.
A note on scope: ordinance thresholds and cycles change as cities amend their codes, and the cost figures are vendor guide-level ranges for New York City, not an audited survey. Individual figures vary by building and should be confirmed against the current code and a licensed professional. This reference documents the landscape as published in September 2026.
Facade inspection in the US, by the numbers
All 35 figures, grouped by theme, each from a named public source and independently verified.
The laws and the deaths behind them
Facade inspection laws are written in response to fatalities. According to Gothamist's 2019 reporting (gothamist.com), New York City's program traces back to the 1979 death of Grace Gold, a 17-year-old Barnard College freshman struck by masonry that fell from a Columbia University building, and forty years later to the 2019 death of architect Erica Tishman near Times Square. According to FirstService Residential's FISP explainer (fsresidential.com), the city passed Local Law 10 in 1980 in response, then the far more comprehensive Local Law 11 in 1998.
Statistic 1
New York City's facade inspection law was created in 1980, when it passed Local Law 10 after a student was killed by a terra cotta coping stone that fell from a building.
FirstService Residential, FISP explainer (2020)
Statistic 2
In 1979, Grace Gold, a 17-year-old Barnard College freshman, was fatally struck by masonry that fell from a Columbia University building on 115th Street.
Gothamist (2019)
Statistic 3
The most drastic revision came in 1998, when New York enacted Local Law 11, requiring more comprehensive facade investigations and detailed reporting.
FirstService Residential, FISP explainer (2020)
Statistic 4
In December 2019, architect Erica Tishman, 60, was killed by facade material that fell from a 17-story office building near Times Square that had been cited for a damaged facade months earlier.
Gothamist (2019)
Statistic 5
In 2015, a two-year-old girl died on the Upper West Side after a piece of a terra cotta windowsill broke off from an eight-story building.
Gothamist (2019)
Statistic 6
Terra cotta is a leading culprit in facade failures. In 1911, one out of every two buildings constructed in New York City was made from terra cotta.
Gothamist, citing Friends of Terra Cotta (2019)
What this means: These are the incidents that turned facade condition from a maintenance preference into a legal duty. The through-line, decades apart, is a facade that was deteriorating in plain view but not documented or acted on in time.
Facade ordinances by city
At least a dozen US cities require periodic facade inspections. According to the city ordinance summaries maintained by Wiss, Janney, Elstner Associates (facadeordinance.com), thresholds and cycles vary widely: New York and Philadelphia cover buildings over six stories, Boston covers walls over 70 feet, Chicago covers buildings 80 feet or taller, and San Francisco and Detroit cover buildings of five or more stories. Most cities use a five-year cycle; San Francisco uses ten years, and St. Louis inspects balconies, fire escapes, and cornices every three.
| City | Law / code | Buildings covered | Cycle |
|---|---|---|---|
| New York | Local Law 11 (FISP) | More than 6 stories | 5 yr |
| Chicago | Muni. Code 14A-6-603.2 | 80 ft or taller | Varies |
| Boston | Building Code 9-9.12 | Walls over 70 ft | 5 yr |
| Philadelphia | Property Maint. subcode PM | 6 or more stories | 5 yr |
| San Francisco | Existing Bldg Code Ch. 5F / AB-110 | 5 or more stories | 10 yr |
| Pittsburgh | City Code Ch. 1004 (IPMC) | All except R-3 dwellings | 5 yr |
| Detroit | Prop. Maint. Code 8-15-34 | 5 stories or greater | Periodic |

Facade ordinance summary, WJE (2026)
Statistic 15
St. Louis requires exterior balconies, stairways and fire escapes on all buildings, and cornices on buildings over five stories or 60 feet, to be inspected every three years, under City Ordinance 70794.
Facade ordinance summary, WJE (2026)
Statistic 16
Columbus requires a critical observation every five years for buildings twenty years or older with a facade within ten feet of a public right-of-way, under Building Code Section 4109.073.
Facade ordinance summary, WJE (2026)
What this means: There is no single national standard. A portfolio owner operating across cities faces different height triggers, different cycles, and different code sections in each one, which is exactly why keeping a dated, documented condition record for every building matters.
NYC FISP filing outcomes
New York's program is the largest and best-documented. According to Hoffmann Architects and Engineers' 2025 Cycle 10 bulletin (hoffarch.com), the number of covered buildings has grown to more than 16,000. According to Habitat Magazine's 2026 analysis of NYC Open Data (habitatmag.com), 13.3% of filings in the latest cycle were rated unsafe, up from less than 1% two decades ago, a jump engineers attribute largely to stricter DOB review rather than sudden deterioration.
Statistic 17
The number of NYC buildings covered by FISP has grown from around 12,500 in 2007 to more than 16,000 today.
Hoffmann Architects and Engineers, Cycle 10 bulletin (2025)
Statistic 18
In the latest FISP cycle, 13.3% of NYC facade inspection filings were classified as unsafe, up sharply from less than 1% two decades earlier.
Habitat Magazine, NYC Open Data analysis (2026)
Statistic 19
Under FISP, building owners must correct an Unsafe facade condition within 90 days of the date the DOB was notified.

Statistic 21
A 2025 NYC legislative package added separate penalties of $5,000 to $20,000 for slow facade repairs.
Rimkus, Local Law 11 history (2026)
Statistic 22
Failing to file a required FISP report draws fines starting at $1,000 per month, and failing to maintain protective measures after an Unsafe designation can bring fines up to $5,000 per month.
DOBGuard, NYC facade inspection guide (2026)
What this means: A rising unsafe rate is as much a documentation story as a construction story. When reviewers demand photographic proof of condition and reclassify anything that looks unsafe, the buildings with thin or stale documentation are the ones that get downgraded.
Sidewalk sheds and deferred repair
The visible cost of the program is scaffolding. According to the New York City Mayor's Office (nyc.gov), when the Get Sheds Down initiative launched in 2023 the city had roughly 9,000 active sidewalk sheds spanning more than 2 million linear feet, nearly 400 miles, about 3 percent of the city's sidewalk space. According to Habitat Magazine's 2026 analysis (habitatmag.com), those sheds stay up for an average of 498 days as owners work through repairs.
Statistic 23
When NYC launched Get Sheds Down in 2023, the city had approximately 9,000 active, permitted construction sheds.

Statistic 25
A 2026 analysis found NYC sidewalk sheds remain in place for an average of 498 days.
Habitat Magazine, NYC Open Data analysis (2026)
Statistic 26
A required sidewalk shed costs $10,000 to $30,000 or more per month in rental and maintenance and must stay up until repairs are complete.
DOBGuard, NYC facade inspection guide (2026)
What this means: A shed is a meter that runs for well over a year. The clearest way to shorten it is to catch and stage repairs before an inspection forces an Unsafe filing, which is a documentation and monitoring problem more than a construction one.
Inspection and repair costs
Compliance is expensive, and the inspection is the small part. According to PermitExpertsNYC's 2026 facade inspection guide (permitexpertsnyc.com), the inspection alone runs $5,000 to $25,000 or more, while needed repairs typically run $50,000 to $500,000 or more. According to DOBGuard's 2026 guide (dobguard.com), a small 7-to-10-story building runs $5,000 to $15,000 for the inspection and report. These are vendor guide ranges for New York City, not audited figures.
Statistic 27
A FISP facade inspection in NYC costs $5,000 to $25,000 or more for the qualified inspector's work alone, depending on building height and complexity.

Statistic 28
For a small NYC building of 7 to 10 stories, the FISP inspection and report typically cost $5,000 to $15,000.
DOBGuard, NYC facade inspection guide (2026)
Statistic 29
Repointing, or replacing mortar, costs $20 to $35 per square foot and is one of the most common facade repairs in NYC.
PermitExpertsNYC, facade inspection guide (2026)
Statistic 30
Lintel replacement typically costs $3,000 to $8,000 per lintel, and a building with 50 to 100 windows can face $200,000 or more in lintel work alone.
PermitExpertsNYC, facade inspection guide (2026)
Statistic 31
Terra cotta repair or replacement is some of the most expensive facade work, at $500 or more per square foot for custom replacement pieces.

Statistic 32
Concrete spalling repair runs $30 to $60 per square foot, and re-caulking runs $5 to $15 per linear foot.
PermitExpertsNYC, facade inspection guide (2026)
Statistic 33
A full facade restoration on a large NYC building runs $150,000 to $500,000 or more, on top of the inspection fee and any required sidewalk shed.
PermitExpertsNYC, facade inspection guide (2026)
Statistic 34
When facade repairs are needed in NYC, the work typically runs $50,000 to $500,000 or more depending on the scope.
PermitExpertsNYC, facade inspection guide (2026)
Statistic 35
A small mortar issue that costs about $5,000 to fix in year one can become a $50,000 problem by year five if water has been getting in.
PermitExpertsNYC, facade inspection guide (2026)
What this means: The cost curve rewards early detection. A defect caught small is a repointing line item; the same defect found five years later, after water intrusion, is a restoration project plus a shed running $10,000 or more a month. Consistent condition documentation between mandated inspections is what keeps a repair on the cheap end of that curve.
