About this site — and why you can trust the numbers
What this site is
Rental Dossier is an independent, English-language guide to one specific problem: putting together a winning apartment application in Switzerland. Tools first — the dossier check and the cover letter generator — with guides around them. It is built and maintained independently by Pavlo Popov — see the imprint for full operator details.
Our data methodology
Every figure on this site follows three rules:
- Official source first. Fees, legal limits and procedures link to the federal or cantonal page they come from — you can verify everything yourself.
- Dated freshness. Data-bearing pages show a “Last checked” badge with the date we last re-verified the facts against the source.
- No invented numbers. Where an exact figure isn’t public (for example, insurer premiums hidden behind calculators), we say so and give a range marked as an estimate.
Privacy by design
Our tools run entirely in your browser. Your answers, salary details and letters are never uploaded, stored or seen by us. See the privacy policy.
