Summary
Anyone who wants to build a house in Switzerland cannot avoid one decisive moment: the building application. With it the permit application is officially submitted to the municipality, and at the end of the procedure stands the building permit. Only once that permit is in hand may ground be broken.
For private clients this phase is often hard to grasp. Which documents are needed? What happens during the procedure? And what can go wrong? This article gives you a well founded overview of the construction project phase, the building application and the path to the building permit in Switzerland.

Is your building application due?
A properly prepared building application saves time in the procedure and avoids follow up requests.
1. What is the building application and why is it so important?
The building application is the submission of the permit application to the competent building authority, as a rule the municipality. With it the pure planning phase ends and the official permit procedure begins. The building permit that stands at the end of this procedure is the legal basis for everything that follows: detailed design, tendering and construction.
The building application is therefore not an administrative interim step, it is a milestone. It marks the moment when a private building project becomes public for the first time. The project is examined by the authorities, neighbours are informed, and objections can be raised.
For clients this means that whatever is unresolved or incomplete by the time of the building application will come to light here at the latest. And that can become expensive.
2. The construction project phase: what is developed before submission?
Between the preliminary design and the actual building application lies the construction project phase. This phase is intensive and often underestimated. On the basis of the approved preliminary design, all planning principles are deepened and made concrete.
What is worked out in this phase:
Floor plans and sections at submission level. The plans are taken from the conceptual level to the level of detail that the building application requires. Room sizes, openings, floor heights, roof shape and facade design are specified and definitively fixed.
Compliance certificates under building law. The project is checked against the provisions of the zoning plan, the building regulations and further cantonal and municipal rules. This includes boundary setbacks, building heights, the utilisation ratio, the zoning status and much more.
Site servicing and building services. The connection to road, water, waste water and electricity is planned in concrete terms and coordinated with the responsible offices. The same applies to parking and any fire brigade access routes.
Aspects relating to the neighbours. Boundary setbacks, views and sunlight on the neighbouring plots are examined. In this phase it is worth seeking dialogue with the affected neighbours at an early stage.
Specialist consultants. Depending on the project, fire safety experts, energy specialists, geotechnical engineers or further specialists are brought in. Their reports and certificates feed into the submission documents.
At the end of the construction project phase all documents required for submitting the building application are available. The more carefully this phase is carried out, the more smoothly the permit procedure runs.
3. What belongs in a building application?
The exact requirements for a building application vary from canton to canton and from municipality to municipality. In principle a complete building application comprises the following documents:
Site plan. An official cadastral plan showing the new building, the building dimensions, the distances to boundaries and neighbouring buildings as well as details of the site servicing.
Plans of the new building. Floor plans of all storeys, sections and elevations at a scale of 1:100 or larger. Where applicable also landscaping plans and unfolded facade elevations.
Technical certificates. Depending on the project: energy certificate (MINERGIE, SIA 380/1), drainage application, fire safety certificate, preliminary structural calculations, sound insulation certificate.
Forms of the municipality and the canton. Building application forms, self declarations, forms for parking spaces and any forms for the municipal or cantonal development plan.
Photos and visualisations. Many municipalities require photos of the existing situation as well as photorealistic or perspective views of the new building in its context.
Proof of ownership and powers of attorney. As a rule the consent of all landowners is required, and in the case of condominium ownership also that of the owners' association.
In individual cases, for example for projects in water protection zones, on protected objects or where overriding federal law applies (such as road law or aviation law), further cantonal or federal offices are involved in assessing the application.
4. The building permit procedure: step by step
Once the application has been submitted, the formal procedure begins. Here too there are differences between the cantons, but the basic sequence is similar everywhere.
Submission and completeness check. The municipality first checks the application for completeness. If documents are missing, the applicant is asked to submit them. As a rule the permit deadline only starts to run once the application is complete.
Publication and public inspection. The building application is published in the cantonal or municipal official gazette and is open to public inspection during an objection period of usually 20 to 30 days. During this time affected third parties, that is neighbours and other persons entitled to object, can file an objection.
Joint consultation procedure. At the same time the application is forwarded to all competent specialist departments, for example the cantonal roads office, the environmental office, the heritage protection office or the fire brigade. These issue statements that feed into the assessment.
Assessment, requirements and conditions. The building authority consolidates all statements and grants the building permit, as a rule with a number of requirements and conditions. Requirements have to be met before or during construction. Conditions make the permit dependent on specific prerequisites.
Objection procedure. If objections have been raised, the authority has to assess them. Objections can lead to negotiations, to corrections of the project or to the rejection of individual parts of the project.
Appeal periods. Once the building permit has been granted, an appeal period runs, usually 30 days. Only when it has expired and no appeals have been lodged does the permit become final and binding. Only then may construction start.
In Switzerland the processing time from submission to a final and binding permit is between 3 and 12 months, depending on the municipality, the canton and the complexity of the project. For demanding projects or in the event of objections it can take considerably longer.
5. Costs of the building application and building permit
The costs connected with the building application fall into two areas:
Planning costs for the construction project phase. Preparing the submission documents is part of the architect's services. According to the SIA fee regulations, around one fifth of the total fee falls to the construction project phase. How high the fee actually turns out depends on the agreed total fee, the scope of the project and its complexity. If you want to know what a house build costs overall, our overview of house building costs in Switzerland provides a structured basis.
Fees of the building authority. The municipality charges fees for examining the building application. These are usually calculated as a per mille rate of the eligible construction sum and lie between 0.5 and 2 per mille, depending on the municipality.
In addition there are costs for specialist consultants such as energy specialists, fire safety experts or geotechnical engineers, where their reports are required for the building application. These vary considerably depending on the scope of the requirements.
If an objection is raised and the project has to be adjusted, additional planning costs arise. In such cases the expenditure for this phase can increase considerably.
6. Risks and typical mistakes
The building application is the phase in which mistakes from earlier planning steps inevitably become visible. Clients who know the most common risks can counter them early.
Incomplete or faulty documents. A frequent problem is the submission of incomplete application documents. Missing certificates, plans that are not dimensionally accurate or contradictory information lead to the application being sent back. That costs time and causes additional expense, because the architect has to revise the documents and submit them again.
Contradictions with the building regulations. Projects that do not fully comply with the rules of the municipality are sent back or have to be adjusted. This can happen if the building law situation was not analysed carefully or if the building regulations changed between the preliminary design and the building application. Anyone who pays attention to the building law situation as early as buying the plot and carries out a careful site analysis avoids such surprises.
Missing coordination with the specialist departments. In practice it happens that specialist departments such as the roads office or the environmental office only come into contact with the project during the permit procedure. Requirements then arise that can change the project considerably. It is better to involve these offices in the planning as early as the preliminary design or the construction project phase.
Too little lead time planned. Many clients underestimate how long the procedure takes. Anyone who submits in spring and wants to start building in summer is often disappointed. A realistic lead time is at least 6 to 9 months from the end of the construction project phase to the final and binding permit.
Deficient architectural services. The quality of the submission documents depends heavily on the architect. Anyone who goes for the cheapest provider or agrees the services inadequately runs the risk of ending up with incomplete plans. Our article on finding the right architect explains what matters when making that choice.
7. Objections: causes, consequences and handling
Objections from neighbours are a real risk in any new build project. They can extend the procedure by months or even years and, in the worst case, force a complete revision of the project.
Typical grounds for objection. Objections are most frequently raised because of impairment of the view, insufficient boundary setbacks, shading, immissions (noise, traffic) or aesthetic concerns. Sometimes personal conflicts or a fundamental rejection of the new building also play a part.
Legal basis. Those entitled to object are as a rule the immediately neighbouring landowners as well as organisations to which cantonal law grants a right of objection, for example nature and heritage protection organisations in the case of correspondingly protected objects.
Early communication with the neighbours. The most effective means against objections is personal communication with the neighbours before the application is submitted. Anyone who informs the affected neighbours early, answers their questions and is prepared to adjust the project on points of detail reduces the risk of objections considerably. Many objections arise from a lack of information or from the feeling of having been passed over.
What happens in the objection procedure. Once an objection has been received, the authority as a rule invites the parties to an attempt at settlement. If agreement is reached, the objection can be withdrawn. If the attempt fails, the building authority decides. Its decision can be taken further, up to the cantonal administrative court.
Costly consequences. Every objection costs time. Even if it is ultimately dismissed, it extends the procedure by weeks or months. During this time planning costs, project financing costs and any rental costs continue to run. Professional owner's advisory helps to identify objection risks early and to minimise them through targeted planning and communication.
8. What does the building permit in Switzerland mean for your project?
A final and binding building permit is an important milestone, but not yet the starting signal. It lays down what may be built and how. This means that the approved plans are binding. Anyone who departs from the project during construction risks a subsequent complaint, a stop work order or even a demolition order.
Period of validity. Building permits are limited in time. In most cantons a period of two to three years applies within which construction must start. If this deadline is not met, the permit lapses.
Next steps after the permit. After the building permit comes the execution project: the detailed planning of all building elements, construction details, materials and building services systems at execution level. Only on this basis can tenders be obtained from contractors.
Notification duties under building law. In many cantons the start of construction has to be reported to the municipality. During the construction phase official building inspections usually take place. After completion the final acceptance follows, at which it is checked whether the building has been erected in conformity with the permit.
Conclusion: well prepared for the building application
The building application is more than an administrative act. It is the result of an intensive planning phase and the first moment in which your building project has to withstand broad scrutiny. Anyone who knows the risks, plans in good time and insists on careful architectural work lays the foundation for a smooth permit procedure.
9. Frequently asked questions about building applications and building permits
How long does the building permit procedure take in Switzerland? From submission to a final and binding building permit it takes between 3 and 12 months, depending on the municipality, the canton and the complexity of the project. For demanding projects or in the event of objections it can take considerably longer. From the end of the construction project phase, plan realistically for a lead time of at least 6 to 9 months.
When may you start building after the building permit has been granted? Once the building permit has been granted, an appeal period of usually 30 days runs. Only when this period has expired and no appeals have been lodged does the permit become final and binding. Only then may construction start.
How long do neighbours have to file an objection? The building application is published in the cantonal or municipal official gazette and is open to public inspection during an objection period of usually 20 to 30 days. During this time affected third parties can file an objection, that is neighbours and other persons entitled to object. Those entitled to object are as a rule the immediately neighbouring landowners as well as organisations to which cantonal law grants a right of objection.
What fees should you expect for the examination of the building application? The municipality charges fees for examining the building application. These are usually calculated as a per mille rate of the eligible construction sum and lie between 0.5 and 2 per mille, depending on the municipality. In addition there are the planning costs of the construction project phase as well as costs for specialist consultants, where their reports are required for the building application.
How long does a granted building permit remain valid? Building permits are limited in time. In most cantons a period of two to three years applies within which construction must start. If this deadline is not met, the permit lapses.
What happens if you depart from the approved plans during construction? The approved plans are binding. Anyone who departs from the project during construction risks a subsequent complaint, a stop work order or even a demolition order. After completion the final acceptance also follows, at which it is checked whether the building has been erected in conformity with the permit.
