Can a landlord reject an application simply because there are children in the family?

Under Swiss law, the mere presence of children cannot in itself be a reason for rejection. However, the landlord may assess whether the flat is suitable for the size of the household and whether the applicant is financially able to pay the rent.

What documents are required for a Swiss housing application?

Usually a copy of your passport or identity card, the residence permit, proof of income for the last three months, a Betreibungsauszug, and a reference from a previous landlord. If you have several children or a pet, a short motivation letter is also recommended.

What is a Betreibungsauszug, and why is it important?

A Betreibungsauszug is an extract from the debt enforcement register showing whether there are any debts under enforcement. In Switzerland, it is one of the most important documents in a housing application, because the landlord uses it to assess your payment reliability.

Can you keep a pet in a rented flat in Switzerland?

Small pets are generally not subject to a blanket ban by the landlord if they do not cause damage, noise or disturbance. For dogs and cats, however, the contract often requires separate consent, and the landlord may refuse permission for justified reasons.

How much deposit can be requested in Switzerland?

The legal maximum is three months’ net rent. The deposit is not handed directly to the landlord; instead, it is placed in a blocked bank account or replaced by a guarantee.

What should you pay attention to when signing a tenancy agreement?

In particular, the notice period, clauses relating to pets, any ban on subletting and Airbnb, and maintenance and painting obligations. It is also important to note that the rent may change if the reference interest rate changes.

Why is it harder to find a flat with a pet or a larger family?

Because there are few vacant flats on the Swiss market and landlords can choose from many applications. With pets, many listings exclude applicants from the outset, while for larger families the flat size and financial capacity are subject to stricter screening.

Finding a flat with family or a pet: how does it work in Switzerland?

What is the Swiss housing market like, and why is it so hard to get by on it?

The Swiss rental market (Mietmarkt) is one of the most competitive in Europe. According to data from the Federal Statistical Office (Bundesamt für Statistik, BFS), the national average vacancy rate (Leerstandsquote) was around 1.15% in 2023 — in some cities, such as Zürich and Genève, it was even lower. This means that a single advertised apartment can typically attract 20–80 applications.

The vast majority of apartments in Switzerland are rented: around 60% of households live in rental housing. Rental relationships are regulated at federal level by the Code of Obligations (Obligationenrecht, OR), especially Articles 253–274. This provides a uniform framework, but local customs and cantonal enforcement can differ significantly.

What is worth knowing at the outset:

Rental prices (Mietzins / loyer) vary dramatically by region. In Zürich, Genève and Basel, the monthly rent for a 3.5-room apartment in 2025 typically ranges from CHF 2 200 to CHF 4 000; in smaller towns and rural areas, it can be CHF 1 200 to CHF 2 200.
In addition to the rent, Nebenkosten (utility advance payments) are usually charged as well, amounting to CHF 100–300 per month.
The average time needed to find a flat in active major cities can be 3–6 months.

What rights do families with children have?

Swiss law does not allow a landlord (Vermieter / bailleur) to reject an applicant because children are present. Under the OR and federal anti-discrimination principles, the number of children alone cannot be a reason for refusal.

In practice, however, the picture is more nuanced. Landlords may lawfully consider:

Whether the apartment is suitable in size: if a family of six applies for a two-room apartment, the landlord may argue that the apartment is not suitable for accommodating that many residents. This is not discrimination, but an assessment of whether the property is being used as intended.
Financial capacity: as a rule of thumb in Switzerland, gross monthly income should be at least three times the monthly rent. For families with children, this implies higher expenses, so landlords examine payment capacity particularly carefully.
References: positive feedback from previous landlords carries significant weight.

Practical advice: if you are looking for a flat with several children, include proof with your application that childcare during the day (Kita, school) is secured. This is not mandatory, but it signals organisation and reduces the landlord’s sense of risk.

School districts and choosing a flat

In Switzerland, primary school (Volksschule / école primaire) is organised by catchment area: children attend the school assigned to their place of residence. If school choice matters — for example, access to a Hungarian weekend school or the quality of a particular institution — it is worth mapping this out before starting the flat search and adjusting the search area accordingly.

What rules apply to pets in Switzerland?

Keeping pets (Tierhaltung) is one of the most common sources of conflict between tenants and landlords in Switzerland.

What does the law say?

Under Article 256a of the OR, the landlord may not generally prohibit keeping small pets if they do not cause damage, noise or inconvenience to other residents. This applies, for example, to aquarium fish, small rodents and birds.

The situation is more complex in the case of dogs and cats:

The landlord may stipulate in the rental agreement (Mietvertrag / contrat de bail) a written consent requirement (Zustimmungspflicht) for keeping dogs and cats.
If such a clause is included in the contract, the landlord may refuse consent — but only if there is a valid reason to do so (e.g. the size of the apartment, the nature of the building, or previous damage incidents).
If the contract is silent on the matter, the tenant may request permission, and the landlord may reject it only for justified reasons.

Cantonal and municipal rules

Keeping pets may also be regulated by cantonal and communal ordinances, especially in the following areas:

Dog tax (Hundesteuer): mandatory in almost every canton; the annual amount ranges from CHF 50 to CHF 200 depending on the canton.
Licence and chip: in Switzerland, every dog must be registered in the AMICUS database (the system of the Federal Food Safety and Veterinary Office, BLV). Keeping the microchip and vaccinations up to date is mandatory.
Dangerous dog breeds: in some cantons (e.g. Geneva, Vaud), keeping certain breeds requires a permit or is prohibited.

How does a pet make the search more difficult?

In practice, applicants with a dog or cat face a narrower field of options. Many listings explicitly exclude pets (Keine Haustiere / pas d'animaux), and this is legally permissible if the contract terms set this out in advance.

Proven approach: attach a short “pet profile” to the application — a photo, breed, age, proof of vaccinations, and possibly a statement from the previous landlord confirming that the animal caused no damage. This does not guarantee success, but it creates a professional impression.

How does the apartment search work step by step?

1. Online platforms

The vast majority of apartment searches in Switzerland start online. The most important platforms are:

Platform	Type	Note
homegate.ch	General, largest	Widest selection
immoscout24.ch	General	Also a leading platform
comparis.ch	Comparison	Comparing fees and offers
anibis.ch	Classifieds	Also from private individuals
tutti.ch	Classifieds	Strong in smaller towns
wgzimmer.ch	Room for rent / shared flat	For singles, young people

2. Local customs and personal connections

In Switzerland, apartment offers spread by word of mouth (Mundpropaganda) are not uncommon. It is worth:

Joining local community groups (Facebook groups, e.g. “Magyarok Zürichben”, “Magyarok Bernben”).
Asking colleagues at work — many companies maintain contacts with property managers.
Contacting the managers of residential buildings directly (Hausverwaltung / gérance), who sometimes inform interested parties before an ad is published.

3. The viewing (Wohnungsbesichtigung)

Arrive punctually and appropriately dressed for the viewing. Bring all required documents with you — many landlords ask for the application immediately at the end of the viewing.

What should the application dossier include?

A complete Swiss apartment application dossier (Bewerbungsdossier / dossier de candidature) usually includes the following:

Copy of identity document (passport or ID card)
Copy of residence permit (Ausländerausweis — B, C or L permit)
Proof of income (Lohnausweis / payslip, for the last 3 months)
Betriebsauszug / Schuldenregisterauszug — debt register extract (Betreibungsregisterauszug): this is one of the most important documents; it confirms that no enforcement proceedings are pending against you. It can be requested from the local Betreibungsamt, and the fee is typically around 17–20 CHF.
References from previous landlords (in writing)
Cover letter (optional, but recommended — especially if you have pets or more than one child)

Important from a Hungarian perspective: if you have recently arrived in Switzerland and do not yet have a Swiss Betreibungsauszug, mention this in your application and attach instead a certificate showing that no enforcement proceedings were initiated against you in Hungary either. This is not equivalent, but it is better than saying nothing.

What should you read carefully in the rental contract?

The Swiss rental contract (Mietvertrag / contrat de bail) is usually a standard form, but the additional terms (Zusatzvereinbarungen / clauses complémentaires) may contain individual provisions.

Pay particular attention to the following:

Notice period and deadlines (Kündigungsfrist / délai de résiliation): the statutory minimum is usually 3 months, but the contract may also require a longer notice period.
Pet clause: if permission is conditional, what exactly is the condition?
Subletting and sleeping-in prohibition: many contracts prohibit Airbnb-style rentals and subletting (Untermiete) without the landlord’s consent.
Renovation and maintenance obligations: what is the tenant’s responsibility (minor repairs, painting when moving out)?
Indexation clause: the rent is tied to changes in the Swiss reference interest rate (Referenzzinssatz / taux de référence hypothécaire). If the reference rate rises, the landlord may request a rent increase; if it falls, the tenant may request a rent reduction.

How much security deposit must be paid, and how does it work?

The legal maximum for the Swiss rental deposit (Mietkaution / dépôt de garantie) is 3 months’ net rent (OR Article 257e). You may not hand this directly to the landlord — it must be placed in a blocked account at a bank specializing in this purpose (Depot-Konto), to which the landlord has no access during the tenancy.

An alternative is a rental guarantee insurance (Mietkautionsversicherung), offered for example by Firstcaution, SwissCaution or Zurich Insurance. In this case, you do not need to tie up the full amount — you pay an annual premium to the insurer (typically 3–5% of the deposit amount per year). This can be especially useful if liquid funds are tight at the start.

How should you plan your budget?

When planning housing costs, take the following items into account:

Item	Typical amount
Monthly rent (Mietzins)	Depends on the region, CHF 1 200–4 000+
Utilities advance payment (Nebenkosten)	CHF 100–300/month
Security deposit (one-off)	2–3 months’ rent
Betreibungsauszug	~CHF 17–20
Possible agency fee	Rare, but it can occur: 1–2 months’ rent
Household insurance (Hausratversicherung)	CHF 150–400/year
Dog tax (if applicable)	CHF 50–200/year, depending on the canton

A hidden cost that many people overlook: the painting and cleaning obligations when moving out. If you do not return the apartment in “tenant-ready” condition, the landlord will deduct the restoration costs from the deposit. Professional end-of-tenancy cleaning (Endreinigung) for an average apartment can cost CHF 500–1 500.

What are the most common pitfalls from a Hungarian perspective?

1. Incomplete documentation. In Switzerland, a complete application is a basic requirement. A missing document may cause the application to be disregarded.

2. Missing Betreibungsauszug. New arrivals from Hungary do not have a Swiss debt register extract. This should be communicated proactively and, where possible, supplemented with a Hungarian equivalent (e.g. KHR extract, court certificate of no record) — although these are not equivalent, they do indicate good faith.

3. Misunderstanding the reference interest rate. Many people do not realise that rent is not fixed forever: when the Swiss reference interest rate changes, the landlord may lawfully adjust it. In 2023–2024, the rate increased, which led to rent hikes for many tenants.

4. Failing to disclose pets. If you do not mention a pet in the application and the landlord later finds out, this may constitute a breach of contract and can even lead to termination.

5. Ignoring notice periods. In Switzerland, notice must be submitted exactly by the deadline set out in the contract — typically 31 March, 30 June or 30 September, three months in advance. Being even one day late means the tenant remains until the next termination date.

6. The issue of brokerage fees. In Switzerland, the landlord pays the agent, not the tenant — if someone asks you for a tenant fee, that is suspicious and is generally not legally enforceable.
