Civil defence shelter guidance in Finland has been updated with three new official guides aimed at building owners and operators, after the Ministry of the Interior (Ministry of the Interior; Sisäministeriö) said it wants to strengthen resilience and improve preparedness across the population. The guidance, published on 21 January 2026, focuses on how shelters should be planned for, maintained, inspected and, if needed, brought into use.
Finland has around 50,500 civil defence shelters with capacity for about 4.8 million people, according to the ministry—against a population of roughly 5.66 million. Many shelters are located in the basements of apartment buildings, which means everyday readiness depends largely on housing companies and other property operators.
What the new civil defence shelter guidance covers
The Ministry of the Interior said the three guides provide practical instructions on:
- planning for the activation and use of a civil defence shelter as part of a building’s emergency planning;
- regular maintenance and inspections to ensure shelters remain functional;
- drawing up an emergency plan for the property.
The ministry framed the update as an effort to harmonise practices across Finland and clarify obligations for different actors, including rescue authorities that supervise compliance.
Property owners’ responsibility and the recommended “named person”
In Finland, the owner or holder of the building is responsible for keeping a shelter in working order. For residential properties, that typically means the housing company’s board or the operator managing the building.
The ministry recommends appointing a designated person to oversee maintenance and periodic checks. The aim is to ensure routine tasks are carried out consistently and to avoid larger repair needs later.
Inspection cycles and the ten-year operational check
A key point in the guidance is that shelters should not be treated as “one-off” infrastructure. Beyond routine servicing, the operational condition of a civil defence shelter must be inspected at least every ten years.
For many housing companies, this requirement is designed to make preparedness measurable: documentation, scheduled checks, and clearly assigned responsibility reduce the risk that shelters degrade slowly through neglect, ad hoc renovations, or incompatible storage.
Shelters in everyday use and the 72-hour readiness rule
In normal conditions, Finland’s civil defence shelters are often used as storage rooms or shared facilities. The ministry underlined that such everyday use is allowed only if it does not compromise the shelter’s functionality.
A central expectation is rapid conversion: shelters must be capable of being emptied and taken into use within 72 hours. The new guidance emphasises planning for that transition—covering practical issues such as preparing the space, activating technical systems, and organising access and movement into the shelter.
When shelters would be activated and what they protect against
The ministry stressed that shelters would be activated only if necessary and with advance notice, adding that Finland is not currently facing a military threat.
Civil defence shelters are primarily intended for situations involving military threat and can protect against the effects of explosions and splinters, building collapse and blast pressure, as well as radiation and substances hazardous to health. In practice, this makes shelters part of Finland’s broader approach to crisis management and civilian protection.
How shelter obligations are defined under the Rescue Act
Finland’s requirement to build civil defence shelters is nationwide. Under the Rescue Act, a shelter must generally be built for a building (or group of buildings on the same plot) used as a permanent dwelling or workplace when the floor area reaches 1,200 square metres. For industrial buildings, the threshold is 1,500 square metres.
Most shelters—around 85%—are private, reinforced-concrete shelters in individual buildings. Joint shelters are common in properties consisting of several buildings.
Why the updated guidance matters beyond technical compliance
While the new guides target property operators, the ministry also framed preparedness as a wider civic issue. The core message is that shelters remain a standing part of Finland’s security architecture even when they are not in active use.
For residents, the Ministry’s position is that not everyone needs technical expertise, but basic knowledge—where the shelter is, how access works, and what the building’s plan says—reduces confusion and speeds up action if shelters must be activated.
Standardising readiness as Europe debates preparedness
The guidance is part of a longer project to update Finland’s instructions for emergency planning and shelter use, reflecting broader policy goals in the government programme on resilience and preparedness.
More broadly, Finland’s approach is closely watched in European debates about civilian protection and crisis readiness. If the new guides lead to more consistent maintenance and clearer responsibilities across housing companies, Finland could strengthen a model that other EU member states increasingly discuss: preparedness systems that rely on both public supervision and private compliance.
