In France, the vast majority of burglaries in apartment buildings occur on just a handful of floors. The ground floor and the first two floors account for most intrusions, a reality known to law enforcement and insurers. However, recent data reveals a second front: the top floors, targeted by burglars who access them via roofs and terraces, especially in large urban areas. This dual phenomenon reshapes the risk landscape within a building itself.
Intrusions from the roof: the trend that statistics are beginning to document
Content on apartment burglaries almost always focuses on the opposition between ground floor and upper floors. However, field data shows a recent increase in top-floor intrusions in French metropolitan areas.

Burglaries that involve climbing to the top floor exploit terraces, flat roofs, and service access points. This method requires agility, but it offers a decisive advantage: residents on the upper levels are less likely to close their windows and patio doors, convinced that height protects them.
This mode of operation remains minor in volume compared to ground floor break-ins. It is progressing enough for several specialized sources to highlight it as a blind spot in prevention. Analyzing the burglary statistics by floor, we see that the risk does not decrease linearly as one ascends a building.

Ground floor and lower floors: why the burglary risk remains highest there
The ground floor, first, and second floors form what some security professionals call the “low crown” of a building. This is where the majority of apartment burglaries are concentrated.
The reasons relate to the logistics of the break-in. A burglar always prioritizes the speed of escape. On the ground floor, access through a window or balcony takes just a few seconds, and the exit is immediate. On the first and second floors, gutters, neighboring balconies, and nearby trees provide accessible climbing points without equipment.
Windows, the primary point of entry
In apartments located on the lower floors, windows and patio doors are the main entry points. Lightweight roller shutters, single glazing, and windows left ajar during the day are all vulnerabilities exploited in just a few minutes. The front door ranks second in the methods recorded for these levels.
Single-family homes share this vulnerability. They accumulate a high number of openings at ground level and often have less monitored access points (garden, attached garage). Available data confirms that houses are more frequently burglarized than apartments, all else being equal.
Intermediate floors and access control: the factor that changes everything
Intermediate floors (from the third to about the fifth) show a statistically lower risk. However, this relative protection depends on a parameter rarely isolated in general articles: the presence or absence of access control to the building.
In a recent building equipped with a keypad, intercom, and entry video surveillance, the risk gap between the ground floor and the fourth floor is significant. The burglar must overcome several obstacles before even reaching the apartment door.
In contrast, in older buildings without access control systems, this gap narrows considerably. An open lobby or a damaged front door provides free access to all landings. The burglar can ascend without being seen or slowed down, making the intermediate floors almost as exposed as the ground floor.
- Building with modern access control: the risk decreases significantly from the third floor, as each barrier (keypad, intercom, camera) extends the burglar’s exposure time.
- Old building without access control: the risk gap between levels disappears, with the open lobby offering direct access to all landings.
- Building with underground parking: often a neglected access point, allowing complete circumvention of the main access control.
Home insurance and floor: a risk grid that impacts theft guarantees
In recent years, several insurers have incorporated the floor of the apartment into their theft risk assessment criteria. This evolution has concrete consequences on home insurance contracts.
Recent insurance guides, including one from Generali, mention that ground floor or first floor apartments must have enhanced protections to benefit from the best guarantee conditions. Window bars, anti-burglary glazing, secure shutters: without these features, certain openings may be subject to partial exclusions or increased deductibles.
What insurers look at in practice
An insurer’s internal grid combines several parameters beyond just the floor:
- Type of lock on the front door (A2P certification or equivalent).
- Presence of shutters or bars on openings accessible from the outside.
- Existence of an alarm system or remote monitoring, which can reduce the premium.
- Geographical location of the apartment (dense urban areas present a statistically higher risk).
For a tenant or owner on the ground floor, ignoring these requirements means paying for insurance that will provide inadequate coverage in the event of a claim. Checking the physical protection clauses required by their contract before a burglary can prevent disappointments at the time of the claim.
The available data does not allow for precise quantification of the premium gap between a ground floor and a fifth floor, as each insurer applies its own weighting. The principle remains constant: the more accessible the apartment is from the outside, the higher the physical security requirements to maintain full coverage.
The risk of burglary in apartment buildings is not simply a straightforward opposition between lower and upper floors. It plays out on three fronts (lower floors, top floors, poorly secured intermediate floors) and depends as much on the building’s equipment as on the height of the apartment. Insurers understood this before most residents did.
