Building insurance: Mandatory or optional in the canton

Building Insurance — a cantonal-specific obligation

When you move to Switzerland or purchase a residential property, building insurance is one of the most important topics. However, unlike many other countries, there is no uniform answer to the question of whether building insurance is mandatory or optional. The regulation depends on the canton in which your property is located. In some cantons, building insurance is legally mandatory, whilst in others it remains optional. As your advisor, I would like to help you understand the correct situation in your canton.

Mandatory building insurance in most cantons

The majority of Swiss cantons stipulate building insurance. This means that you, as an owner or in some cases as a tenant, are obliged to insure your building against fire and elemental damage (storm, hail, snow pressure). These cantons have established state or semi-state insurance institutions to guarantee this basic insurance. The premiums are typically regulated and uniformly set for all buildings of the same category and region. Examples of cantons with mandatory building insurance include Zurich, Bern, Lucerne and most other cantons in German-speaking Switzerland. You can schedule a consultation appointment for your building insurance to clarify the exact requirements for your situation.

Optional building insurance in individual cantons

A handful of cantons — namely Basel-Stadt, Basel-Landschaft and Schaffhausen — regulate building insurance differently: here, insurance is not mandatory but a matter for the owner. This means you can decide for yourself whether and with which company you wish to be insured. The advantage is greater flexibility; the disadvantage is that you bear the responsibility of being adequately insured. In these cantons, private insurance companies can offer building insurance, which leads to different premiums and coverage options. Even if insurance is optional, it is highly recommended to obtain cover — an uninsured building is a significant financial risk.

Differences for ownership and rental situations

When it comes to the question of who pays for building insurance, there is an important distinction between owners and tenants. Owners are almost always responsible for paying and maintaining building insurance — this is both a legal obligation and their own protection. Tenants, on the other hand, pay an amount towards building insurance through their rent, which the landlord collects. In mandatory cantons, the landlord must provide proof that the building is insured. Should damage occur and the building is not insured, you are personally liable and must cover all costs yourself — often in five or six-figure amounts.

What is typically covered by building insurance?

Standard building insurance coverage protects against fire, lightning, explosion and elemental damage such as storm, hail or snow pressure. In some cantons, damage caused by water from burst pipes or flooding is also included; in others, these must be insured separately. It is important to know: building insurance covers the building envelope and permanently affixed components, but not furniture or personal possessions — for these you need contents insurance. The sum insured should correspond to the replacement value of the building in order to be fully compensated in the event of a claim.

Premiums and cost examples

In mandatory cantons, premiums are calculated according to standardised tariffs, which vary from canton to canton. For an average single-family home with a replacement value of 600,000 CHF, annual premiums in mandatory cantons typically range between 600 and 1,200 CHF per year. The exact amount depends on the canton, the construction type (wood, stone), the age and location of the house. In optional cantons, premiums can vary more significantly depending on the insurance company and the coverage selected. It is worthwhile to regularly check whether the sum insured still corresponds to the current value of the building — inflation and renovations can quickly increase the replacement value.

What to do after purchase or renting?

When you buy a house or acquire a property, you must first find out what insurance obligation applies in your canton. It is best to contact the cantonal insurance office or an advisor such as Helpner to clarify your individual situation. Obtain the documents for the house — in particular a current valuation of the replacement value — and then check whether the current insurance is adequate. For tenants, it is advisable to check building insurance in the rental agreement and ensure that the landlord has accounted for it correctly. Any changes to the building (such as extensions or renovations) must be reported to the insurer.
