In Switzerland the seller’s liability for defects is almost always excluded in the contract. Whatever you did not check before the public deed becomes your cost afterwards. This page is the short version of what that means in practice, written for buyers who do not read German and are looking for an English-speaking home inspector in Zürich.

Before you make an offer

Five things, in this order.

Get your financing confirmed

Swiss banks want at least 20 per cent equity, of which 10 per cent from your own funds rather than your pension, and they test affordability at an imputed 5 per cent interest plus about 1 per cent running costs, capped at a third of gross income. Purchases fail here more often than anywhere else.

Request the documents

Grundbuchauszug, Reglement, the last three years of owners’ meeting minutes, the Erneuerungsfonds statement and the GEAK. A seller who will not produce these usually has a reason.

Read the reserve against the building

Compare the Erneuerungsfonds balance to the age of the roof, façade and heating. An underfunded fund with works due means a Sonderumlage lands on you, regularly five figures.

Inspect before the deed, not after

This is the only moment the findings can still change the price or the decision. Once the Notariat has recorded the sale, the condition of the building is yours.

Check the floor area

Swiss living space is measured under SIA 416 and listings routinely overstate it. At Zurich prices per square metre, a few metres is a five-figure difference.

Same thing, three words

Home inspection, building survey, Baugutachten.

Questions buyers ask

Twelve questions, answered plainly.

I am buying a house or flat in Zurich. What should I do first?

+

Before you make an offer, do three things in parallel. Get a financing confirmation from your bank, because the affordability calculation decides what you can actually buy. Request the building documents from the seller or the Verwaltung: the Grundbuchauszug, the Reglement, the last three years of Stockwerkeigentümerversammlung minutes, the Erneuerungsfonds statement and the GEAK. And book an independent inspection before the public deed, because in Switzerland the warranty is almost always contractually excluded and what you did not check becomes your cost.

Do I need a home inspection when buying in Switzerland?

+

There is no legal requirement, but the Swiss purchase contract usually excludes the seller's liability for defects. That means the condition of the building becomes your problem the moment the deed is signed. An inspection before you commit is the only point at which the information can still change the price or the decision. A Red Flag Check from CHF 750 covers the deal-breaker questions; a full survey from CHF 1'450 prices every defect.

What is the difference between a home inspection and a Baugutachten?

+

They are the same thing described in different languages. 'Home inspection' is the North American term, 'building survey' the British one, and 'Baugutachten' the German and Swiss one. ABC Experts carries out the inspection to the same standard and issues the report in English or German, whichever you need for your bank, your lawyer or yourself.

Can I get a Baugutachten in English in Zurich?

+

Yes. Alice Carpenter inspects in Zurich and reports in English or German. Every finding is photographed, rated and costed in Swiss francs, and the document review covers the German-language Protokolle and Reglement so you do not have to read them yourself. The report is accepted by banks and can be used in price negotiation.

How much does a building inspection cost in Zurich?

+

A Red Flag Check starts at CHF 750 and answers whether there are deal-breakers, with a traffic-light report usually the same day. A full building survey starts at CHF 1'450 and prices every defect for repair, including a review of the sale documents. A remote document review alone is CHF 250. Prices are fixed and agreed before booking.

What should I check in a Zurich apartment before making an offer?

+

The Erneuerungsfonds balance against the age of the roof, façade and heating, because an underfunded reserve means a Sonderumlage lands on you. The minutes of the last three owners' meetings, where disputes and planned works appear. The age of the heating system. Damp in the cellar and in external corners. The floor area against SIA 416, because listings routinely overstate it. And the Reglement, which governs what you may actually do with the flat.

What is the Erneuerungsfonds and how much should be in it?

+

It is the owners' joint reserve for future renovation. A common rule of thumb is annual contributions of 0.5 to 1 per cent of the building's insured value. If the fund is underfunded and a roof or façade renovation is due, your share arrives as an extraordinary contribution, regularly in the five-figure range. Checking this is often worth more than the inspection costs.

How much equity do I need to buy property in Switzerland?

+

Normally at least 20 per cent of the purchase price, of which at least 10 per cent must come from your own funds rather than your pension. Banks then test affordability using an imputed interest rate of around 5 per cent plus roughly 1 per cent for maintenance and running costs, plus amortisation, and the total must not exceed one third of your gross income. Purchases fail more often on affordability than on equity.

Can foreign nationals buy property in Zurich?

+

This is governed by Lex Koller. With a C settlement permit you have the same rights as a Swiss citizen. With a B residence permit you may buy a primary residence at your place of residence without authorisation; second homes and holiday flats require one. Without residence in Switzerland there are substantial restrictions. Clarify your own case with the Notariat before making an offer.

What happens if I find defects after buying?

+

For existing properties the statutory warranty is almost always contractually excluded. An exclusion is only invalid where the seller fraudulently concealed a defect, which is hard to prove in practice, and claims relating to buildings lapse five years after transfer of ownership. This is the single strongest argument for inspecting before the deed rather than after.

Is the apartment really as big as the listing says?

+

Often not. Swiss floor area is measured under SIA 416, and what counts as living space is narrower than most listings imply. Balconies, cellars and sloping ceilings are treated differently from what buyers expect. On a Zurich price per square metre, a discrepancy of a few square metres is a five-figure difference in what you are paying for.

How quickly can you inspect, and when do I get the report?

+

We reply within one working day with available Zurich dates. The written report follows within 24 hours of the inspection, with photographs, traffic-light ratings and repair cost estimates. If you are under an offer deadline, say so when you enquire and we will tell you honestly whether it can be met.
