Zoning Plan Switzerland: All About Residential, Commercial, and Mixed Zones

What is a zoning plan and why is it important?

The zoning plan is a central instrument of spatial planning in Switzerland. Every municipality has a zoning plan that determines which areas are designated for which uses. These plans are based on the Federal Act on Spatial Planning (SPA) and serve to ensure orderly settlement development and avoid conflicts of interest between different uses.

For you as a business operator or property seeker, this means: Before you buy or rent a property, you should definitely check which zone it is located in. Because you are not allowed to carry out every type of business activity everywhere. A restaurant in a purely residential zone? Usually not possible. A production facility in the core zone? Equally difficult. The zoning plan gives you clarity about the permitted uses and building possibilities.

Residential zone: Living takes priority

Residential zones are – as the name suggests – primarily intended for residential uses. They are often divided into different categories, such as W2 (two-story), W3 (three-story), or W4 (multi-story). These designations vary depending on the canton and municipality, but provide information about the permissible building height and density.

Commercial uses are strictly limited in residential zones. As a rule, only so-called "neighborhood-compatible" businesses that do not impair the living environment are permitted. These include, for example, small offices, medical practices, or craft businesses without disruptive emissions. Larger commercial enterprises, production facilities, or shops with high customer traffic are usually not permitted.

Exceptions and permits

In some cases, exceptional permits can be granted if the planned use is compatible with the character of the residential zone. However, this is at the discretion of the building authority and by no means guaranteed. So, if you plan to run a business in a residential zone, you should contact the responsible municipality at an early stage.

Commercial zone: Space for economic activities

Commercial zones are specifically designated for commercial and industrial uses. Here you can set up production facilities, warehouses, workshops, trading companies, and much more. Unlike residential zones, there are fewer restrictions regarding noise, traffic, or operating hours in commercial zones – as long as the legal limits are observed.

Commercial zones are also often further subdivided, for example into "work zones", "industrial zones", or "zones for public uses". You can find the exact designations and regulations in the building and zoning regulations (BZO) of your municipality. Some municipalities, for example, distinguish between low-emission commercial zones (e.g., for offices and services) and industrial zones with higher emission limits.

Living in the commercial zone?

In principle, living in commercial zones is only permitted to a very limited extent. In many cases, only company manager apartments or caretaker apartments are permitted – and even then, only if they are directly related to the business. Entrepreneurs who want to live in their commercial space should clarify this in advance with the building authority.

Mixed zone: Flexibility for living and working

Mixed zones form the compromise between residential and commercial zones. Both residential uses and commercial activities are allowed here – usually with certain conditions. You often find mixed zones in village centers, neighborhood centers, or along main roads, where commerce and living have traditionally existed side by side.

The rules in mixed zones are often more flexible than in purely residential or commercial zones. For example, you can operate a retail space on the ground floor and have apartments above it. Restaurants, offices, studios, or small workshops are also typically permitted. However, restrictions apply here as well: businesses with strong emissions (noise, odor, traffic) are usually not allowed or only with special conditions.

Advantages for Startups and SMEs

Mixed zones are particularly attractive for many startups and SMEs, as they allow the combination of working and living or offer central locations with good accessibility. The rents are often more moderate than in purely commercial zones, and the proximity to residential neighborhoods brings walk-in customers. If you are eyeing a space in a mixed zone, you should nevertheless check exactly which specific uses are permitted.

Building code metrics at a glance

In addition to the type of use, the zoning plan also defines important building code metrics. These determine how intensively a plot of land may be built on. The most important metrics are:

• Utilization factor (AZ): The AZ indicates the ratio between the permissible gross floor area and the plot area. An AZ of 0.5, for example, means that a maximum of 500 m² of floor area may be realized on a 1,000 m² plot.
• Building height: The maximum height of a building is often specified in meters or as a number of stories. This specification is crucial for the economic viability of a construction project.
• Boundary distances: Define how much distance a building must keep from the property boundaries. These distances vary depending on the zone and building type.
• Building coverage ratio: Indicates what percentage of the plot area may be built upon.

These metrics are relevant to you if, for example, you want to expand or remodel an existing property. Even when looking for suitable commercial space, it is worth taking a look at the expansion potential – perhaps the landlord can create additional areas if necessary.

How do you find your municipality's zoning plan?

Zoning plans are publicly accessible. Most Swiss municipalities make their zoning plans available online – either on the municipality's website or via cantonal geoportals. You can enter an address or parcel number there and immediately see which zone the property is located in.

In addition to the zoning plan, you should also consult the building and zoning regulations (BZO). This document contains the detailed regulations for the individual zones, including usage provisions and building code metrics. The BZO is also public and mostly available as a PDF on the municipality's website.

Seek personal advice

If you are unsure whether your planned use is permitted in a certain zone, contact the building authority of your municipality. The staff is usually happy to provide you with information. For more complex projects, consulting an architect or spatial planner can also be useful.

Conclusion: The zoning plan as a planning basis

The zoning plan is much more than a bureaucratic document – it is your most important planning basis when searching for commercial real estate or when building or remodeling properties. Whether residential zone, commercial zone, or mixed zone: Every zone has its own rules and possibilities. Building code metrics such as the utilization factor or building height significantly influence what can be realized on a plot.

If you are looking for a suitable commercial space, pay attention not only to the location and price but also to the zoning plan. This way, you avoid nasty surprises and ensure that your business plans are also legally feasible. If you have questions about zoning or specific uses, the municipality or a technical expert can help you.
