Every two hours and fourteen minutes, someone in the United States dies in a fire. The vast majority of those deaths happen in the same place: at home. Not in a factory, not in an office tower, not in a hotel. At home.
This is not a new trend. For decades, fire data have shown that residential occupancies — houses, apartments, and high-rise buildings — are where the fire problem is most severe. Yet across the United States and around the world, the home is also the building type least likely to be required to have automatic fire sprinkler protection. That disconnect is not an accident. It is written into the code.
What the Numbers Tell Us
In 2024, U.S. fire departments responded to an estimated 329,500 home structure fires — roughly one every 96 seconds. Those fires killed approximately 2,920 people and injured 8,920 more. They caused an estimated $11.4 billion in direct property damage. These figures come from NFPA’s Fire Loss in the United States During 2024, and they tell a consistent story: the residential fire problem is enormous, and it is not going away.
One- and two-family homes bear the heaviest burden. They account for 65.8% of all civilian fire deaths and 56.3% of all fire injuries in the United States. Apartment fires account for another 8.7% of deaths and 19.4% of injuries. Add it up, and residential occupancies account for most fire deaths in this country — year after year.
High-rise residential buildings deserve special attention. According to NFPA’s High-Rise Building Fires (2019–2023), fire departments responded to an estimated average of 14,830 high-rise structure fires per year during that period. Of those, 85% occurred in residential properties — an average of 12,676 fires per year, causing 31 civilian deaths, 408 injuries, and $141 million in property damage annually. In high-rise multi-family buildings with seven or more units, kitchen fires were the leading cause of incidents, accounting for 59%. But bedroom fires — fires that start where people are asleep — caused a disproportionate share of deaths.
People in residential high-rises face a specific set of risks. They sleep. They may be elderly or very young. They share corridors and elevators with many other people. And in many cases around the world, they live in buildings without automatic fire sprinkler protection at all.
Sprinklers Work — So Why Aren’t They Required?
The evidence for automatic fire sprinklers in residential buildings is clear. Homes with sprinklers have an 81% lower civilian death rate than homes without them. When sprinklers and hardwired smoke alarms are both present, the death rate drops 90%. In fires where a sprinkler system operated, civilian death rates from 2015 to 2019 were 89% lower than in fires with no automatic suppression.
A single automatic fire sprinkler activates, applies water directly to the fire, buys time for escape, and in most cases controls the fire entirely — without waiting for the fire department to arrive. The technology is reliable, proven, and cost-effective. And yet automatic extinguishing systems were present in only about 5% of nonconfined fires in occupied residential buildings in recent data.
Why? In the United States, housing and building industry groups have actively opposed residential sprinkler mandates, successfully blocking requirements in at least 25 states. The argument is cost — but cost comparisons rarely account for the cost of a fire. Beyond the United States, many countries simply have not extended sprinkler requirements to residential occupancies at all, regardless of building height.
The São Paulo Example
One of the clearest illustrations of this problem is found in São Paulo, Brazil. Under Decree 69.118, São Paulo’s fire safety regulations classify buildings by occupancy type and set sprinkler requirements accordingly. The result is a striking three-way comparison.
An apartment building — Group A-2 under the decree — is not subject to a sprinkler requirement, regardless of its height. A hotel (Group B-1) requires sprinklers when it exceeds 23 meters (75 feet). An office building (Group D-1) is required to have sprinklers above 30 meters (98 feet).
Consider what this means in practice. A 30-story apartment tower in São Paulo — a building that may house hundreds of residents, including children, elderly people, and people with limited mobility — is not required to have any automatic sprinkler protection. The hotel next door, where guests check in for a few nights, must be fully protected. The office building across the street, which is empty most nights and on weekends, must also be protected above a certain height.
The logic embedded in these codes, in effect, says that the lives of hotel guests and office workers matter more than those of residents. The data on fire deaths says the exact opposite.
São Paulo is not an outlier. Similar gaps exist in fire codes across Latin America, parts of Asia, and the Middle East. The pattern is consistent: residential occupancies are routinely exempted from sprinkler requirements that apply to commercial buildings of the same height and risk profile.
What the Consequences Look Like
These are not abstract policy gaps. They have names and addresses.
On 26 November 2025, a fire broke out at Wang Fuk Court, a residential complex of eight 31-story towers in Tai Po, Hong Kong. The fire burned for more than 43 hours. It killed 168 people — most of them found inside their own apartments — and injured 79 more. Nearly 40% of the complex’s residents were senior citizens aged 65 and above. Seven of eight residential towers were consumed.
Wang Fuk Court was built in 1983 as a subsidized government housing complex and housed approximately 4,643 residents. At the time of the fire, the buildings were undergoing exterior renovation and were wrapped in bamboo scaffolding and construction netting — materials that contributed to the speed and scale of the fire’s spread. The cause remains under investigation. But the outcome is not in dispute: 168 people died in a residential high-rise, and most of them never made it out of their apartments.
This is what the residential fire problem looks like at scale. A building full of residents — many of them elderly, many of them sleeping or unable to escape quickly — with no suppression system to slow the fire in those critical first minutes before help could arrive. The Wang Fuk Court fire is the deadliest in Hong Kong since 1948.
Every year, thousands of people die in fires in their homes — in buildings that could have been protected, in countries with codes that choose not to require it. Every one of those deaths is a policy failure as much as a fire event.
What Needs to Change
Code bodies, policymakers, and fire protection professionals have the tools to address this. Height-based or occupant-load-based sprinkler thresholds — applied consistently regardless of occupancy type — would close the gap that allows a 30-story apartment building to go unprotected while a hotel of the same height is fully covered.
Fire protection engineers can advocate for these thresholds in local code adoption processes. Authorities having jurisdiction can ask the hard question: if we require sprinklers in this hotel, why not in the residential building next to it?
And residents themselves deserve to know whether their building is protected — and to understand that in many places, the answer is no.
The data has been clear for a long time. The fire problem lives at home. The solution does too.
