Procedure, rights, defects and quality criteria
Summary
A property handover in Switzerland, formally the acceptance of the work, is the moment when a building or apartment passes from the builder to the buyer or client. It marks the legal start of the warranty periods and determines which defects can still be claimed later and which are considered accepted. The inspection is primarily regulated by the Swiss Code of Obligations (OR) and, if contractually agreed upon, by SIA Standard 118. For many buyers, it is also an emotional moment when the project, after a long planning phase, is finally completed. It is precisely at this moment that errors often occur, because contracts are signed under time pressure, defects are acknowledged verbally, or documents are handed over incompletely.

Is your final exam coming up soon?
Professional support provides thorough documentation and is worthwhile in relation to the value of your home.
1. What is a property handover in Switzerland?
The final inspection is the formal act by which the buyer or client accepts a building or apartment from the contractor. It is more than just a deadline; it is the legal transfer of responsibility, risk, and warranty claims. With the final inspection, the buyer confirms that the work has been completed substantially in accordance with the contract, and the contractor is released from their obligation to perform, provided no defects have been reported.
In Switzerland, acceptance is regulated by the Swiss Code of Obligations (OR). For contracts for work and services, Articles 367 to 371 OR are particularly relevant. If SIA Standard 118 is contractually agreed upon, its provisions also apply, which in some respects are more favorable to the buyer than the OR.
A building inspection typically includes a joint site visit, an examination of the building based on the contract, building description and plans, the recording of defects in the acceptance protocol, and the handover of keys and documentation.
2. Why is the final inspection of an apartment or house one of the most important moments in a construction project?
The final inspection is the only moment when all three parties (buyer, builder, specialists) stand together in front of the completed building and can clarify its condition. From this point on, the legal relationships change fundamentally.
The following specifically happens during the acceptance process:
The transfer of risk takes place: from now on, any damages are the responsibility of the buyer.
The warranty periods begin to run (usually two and five years, up to ten years for hidden defects).
Visible defects must be reported immediately, otherwise they are considered approved (Art. 370 para. 2 OR or SIA 118 )
The work is generally considered to be completed in accordance with the contract, provided no reservations are recorded.
The remaining payment is usually due.
Anyone who underestimates this moment relinquishes rights they will never regain. That's precisely why careful preparation, in terms of expertise, documentation and timing, is so important.
3. What legal principles apply in Switzerland?
For building inspections in Switzerland, three main levels of regulation are relevant. The hierarchy is clear: mandatory law in the Swiss Code of Obligations (OR) takes precedence, followed by individual contractual provisions, then any agreed-upon SIA standards, and finally the building description with the plans.
Swiss Code of Obligations (CO):
Articles 367 to 371 of the Swiss Code of Obligations (OR) govern contracts for work and services. Visible defects must be reported upon acceptance (Art. 367 OR), hidden defects immediately upon discovery (Art. 370 OR). The limitation period is five years for immovable works (Art. 371 OR), and ten years in cases of intentional concealment.
SIA Standard 118:
The standard regulates the relationship between client and contractor in more detail and is commonly agreed upon in many construction contracts. It stipulates a two-year period for reporting defects and a five-year warranty period. Important: SIA 118 only applies if it is contractually agreed upon.
Works contract and construction description:
These documents define the required standard. Anything not included in the contract or building specifications can be difficult to enforce in case of a dispute, even if it was promised in the sales brochure.
4. What types of building inspection are there?
In practice, different acceptance procedures are carried out depending on the phase and contract. Those who understand the difference can protect their rights at the right time.
Preliminary inspection (informal):
This usually takes place two to four weeks before the official acceptance inspection. It has no direct legal effect, but serves to identify defects early on. The contractor has time to rectify any issues before signing.
Main inspection or official inspection:
The legally binding appointment. Here, all visible defects are recorded in the report, deadlines for rectification are agreed upon, and the handover is formally completed.
2-year warranty purchase:
According to SIA 118, the period for lodging complaints regarding defects that became apparent without further investigation expires after two years. A second inspection within this period is therefore advisable.
5-year warranty purchase:
The period before the five-year warranty expires is the last opportunity to formally claim defects. After that, most claims become time-barred.
5. Who should be present during the acceptance inspection?
The composition of the acceptance team influences how balanced the discussion is and how accurately the minutes are recorded.
Typically present are:
Buyer or developer (mandatory)
Representative of the general contractor, developer or seller
Construction management or architect of the builder
Representatives of key trades on specific issues
Optional: an independent architect or building expert on the buyer's side
Without an independent expert, buyers typically face multiple experts from the opposing side. This isn't necessarily a problem, but it can lead to imbalances when defects need to be discussed or tolerances interpreted.
6. What three levels does a complete acceptance test encompass?
In practice, acceptance testing is often reduced to an on-site inspection. However, a complete acceptance process operates on three interconnected levels.
Level 1, On-site (visible inspection):
Inspection of all rooms, functional testing of equipment and systems, visual inspection of surfaces, doors, windows, blinds, plumbing and electrical installations. This level is covered by most client representatives and is what is commonly understood as "acceptance support".
Level 2, documents and contract:
Comparison of the constructed work with the construction contract, building specifications, sample lists , and selection decisions. It is checked whether materials, models, quantities, and quality levels comply with the contract.
Level 3, Plans and Construction:
The execution is compared with the execution plans and the applicable standards. Wall thicknesses, room heights, construction details, connections, layer structures, and compliance with standards are checked.
Levels 2 and 3 are not typically offered as standard by building owners' representatives in Switzerland. Yet these are precisely the levels at which costly construction defects, faulty workmanship, and long-term negative consequences can be identified. If such issues are not detected during the acceptance inspection, high renovation costs can arise later.
Raumwert Plus deliberately covers all three levels because the greatest part of the risk lies hidden in the documents and plans, not just on the visible surfaces. The appropriate level of detail in the review depends on the project and the contractual situation and will be clarified in a preliminary consultation.
7. What happens if defects go undetected during the acceptance inspection?
Undetected or unreported defects have concrete legal and financial consequences in Switzerland. The full extent often only becomes apparent years later, when damage occurs or the property is to be sold.
Legal consequences:
Visible defects that are not recorded in the protocol are considered approved.
Hidden defects must be reported immediately upon discovery, otherwise the claims are forfeited.
After the warranty period expires (usually five years), most claims are time-barred.
A thorough inspection is not an insurance policy against every risk, but it significantly reduces the likelihood that relevant defects will be detected too late.
8. What is the difference between visible and hidden defects?
This distinction is legally crucial because it determines the time limit within which a defect can be claimed.
Visible defects are those that are recognizable upon careful, proper inspection. Examples include scratches in the parquet flooring, missing electrical outlets, incorrectly installed doors, color discrepancies, and damaged windows. These must be recorded in the inspection report; otherwise, they are considered accepted.
Hidden defects are those that were not apparent during the initial inspection and only become apparent later. Examples include leaks in the building envelope, water damage behind walls, inadequate insulation, mold growth, and construction errors. These defects can be reported during the warranty period, but must be submitted in writing immediately upon discovery.
An important gray area involves defects that would have been recognizable to an expert but not to a layperson. In case of dispute, disagreements can arise as to whether a defect is considered visible or hidden.
9. What is the formal form of a complaint?
A notice of defects is the formal notification to the manufacturer that a defect exists and must be rectified. To be legally valid, it should meet certain requirements.
An effective notice of defects usually contains:
Clear description of the defect (location, type, extent)
Reference to the contractual basis (contract for work and services, building description, plans)
Request for rectification within a reasonable timeframe
Date of discovery (especially important for hidden defects)
Clear identification of the sender and the recipient
Shipping via registered mail or with other proof of delivery
In practice, written form is almost indispensable, even though the Swiss Code of Obligations (OR) does not formally exclude oral objections. Anyone who objects orally and does not record it has no basis for proof in the event of a dispute.
10. What rights do you have as a buyer or building owner in case of defects?
If a defect is properly reported, the buyer in Switzerland has four main rights. Which right is enforceable in a given case depends on the severity of the defect, the contractual situation, and practical considerations.
1. Improvement:
The manufacturer is obligated to rectify the defect at their own expense. This is the most common and usually the most sensible course of action.
2. Reduction:
Reduction of the purchase price by the value of the defect. Applicable if rectification would be disproportionate or the defect cannot be completely remedied.
3. Transformation:
Cancellation of the contract. Only possible in cases of very serious defects that render the work essentially unusable.
4. Damages and right of retention:
Additional damages may be claimed in cases of negligent defects. A reasonable portion of the remaining payment may be withheld until the defects are remedied.
In most cases, it's about rectification. The crucial point is that the defect is properly documented, clearly described, and deadlines are set.
11. What rights do you have if the work deviates significantly from the contract?
Not every defect is equally serious. Minor deviations entitle the buyer to rectification. For significant defects that fundamentally compromise the work's function or conformity with the contract, Swiss law provides a more far-reaching instrument: the refusal of acceptance.
According to Article 368 of the Swiss Code of Obligations (OR), the client is entitled to refuse acceptance of a defective work if the defects are so significant that the work is unusable for them or cannot reasonably be expected to be accepted. A comparable right is also enshrined in SIA Standard 118, provided it is contractually agreed upon.
Refusal to accept delivery means, specifically:
The work is not accepted, the acceptance protocol is not signed.
The transfer of risk does not take place.
The warranty periods do not start.
The remaining payment is not due.
The contractor is obligated to rectify the significant defects within a reasonable timeframe.
A new acceptance date will only be scheduled after the necessary improvements have been made.
Typical cases in which a refusal may be justified:
Essential building components are not yet complete (e.g., missing sanitary installations, incomplete flooring, non-functioning heating)
Safety-related deficiencies (missing railings, defective electrical installations, non-functioning fire doors)
Official final certificates or the authorization to receive the goods are missing.
The materials or constructions used deviate significantly from the contract.
Refusal is a powerful tool and should be used judiciously. In practice, it is often the only way to exert pressure on a defaulting contractor who is not taking completion seriously. It is crucial that the refusal is justified in writing and that the significant defects are clearly identified. Anyone who has to make this decision alone is often under considerable pressure. Professional guidance helps to accurately assess the severity of the defects and to weigh the consequences of refusal against those of conditional acceptance.
12. What documents should you have ready for the acceptance inspection?
An acceptance inspection is only as good as its documentation. Anyone who shows up without documentation cannot compare the completed work with what was agreed upon.
Documents you should bring with you to the inspection:
Contract for work or purchase agreement with all attachments
Construction description and sample inspection reports
Current plans (floor plans, sections, elevations)
Selection lists for materials, equipment and samples
Key protocol
List of open issues from previous inspections or preliminary approvals
Contractually agreed dates and deadlines
Documents you should receive upon acceptance:
Complete object documentation
Revision plans (as-built plans) for electrical, plumbing, heating, ventilation
Operating instructions for all devices and technical systems
Warranty and maintenance documents
Official final certificates (electrical inspection, elevator inspection, fire protection)
Energy performance certificate or Minergie certificate (if available)
Authorization to occupy the property from the municipality
For condominium ownership: regulations and rules of use
If documents are missing, this should be recorded in the acceptance protocol and deadlines should be set.
13. How does a professional acceptance inspection process work?
In practice, a supervised acceptance process follows a clear procedure that includes preparation, inspection, and follow-up. The typical process at raumwert plus is divided into eight steps.
1. Informal meeting:
The project, participants, and key areas are discussed via Teams call. The scope of support is defined jointly.
2. Determining the scope of services:
Selecting the appropriate package depending on complexity and contractual situation.
3. Compilation of documents:
A project-specific list helps the buyer request all relevant documents from the creator.
4. Technical project review in advance:
Depending on the scope, plans, building descriptions and contract documents are checked in advance to identify errors or planning mistakes in the documents.
5. Preliminary inspection on site (optional):
Initial inspection with the contractor to identify defects early and allow time for improvements.
6. Creation of a personal guarantee and legal document:
Based on the purchase agreement, building description and legal framework, an individual document is created that makes the warranty periods and rights regarding defects transparent over ten years.
7. Final inspection:
On-site professional support, assessment of the situation in the context of standards, support in communication with the other party.
8. Follow-up and further support:
Review of the acceptance protocol for completeness and accuracy, support during discussions about defects, availability for follow-up questions.
14. What is a preliminary inspection and when is it useful?
The preliminary inspection is an informal site visit two to four weeks before the official acceptance inspection. It has no direct legal effect, but serves to identify defects early and give the contractor time to rectify them.
A preliminary inspection is particularly useful if:
You can expect many defects or open issues.
The creator is working under time pressure and completion is imminent.
They don't want to have any discussions about fundamental defects during the official inspection.
Complex technical systems need to be tested, which require a break-in period.
The preliminary inspection significantly reduces the burden on the official inspection. Instead of a list with thirty or fifty points, often only a short list of remaining items remains, making the handover process calmer for both parties.
15. What are the 2-year and 5-year warranty acceptances?
These two dates are often forgotten in practice, but are legally crucial.
2-year warranty purchase:
According to SIA 118 (if agreed upon), the two-year period for reporting defects that have appeared after acceptance expires. A systematic inspection shortly before the expiry of this period helps to identify and report newly discovered defects in a timely manner.
5-year warranty purchase:
The last formal opportunity to assert claims for defects within the statutory warranty period (Art. 371 OR). After five years, most claims expire, except in cases of intentional concealment.
Those who let these deadlines pass without an inspection risk forfeiting relevant rights. In practice , professional support is advisable for both deadlines, as hidden defects often become apparent at this time that were not visible during the initial inspection.
16. Three practical examples from Switzerland
Practical example 1: Condominium ownership on Lake Zurich
A buyer takes possession of a 4.5-room apartment in a new development . During the inspection, he notices some scratches on the parquet flooring and a malfunctioning blind, which he has noted in the inspection report. Only a subsequent review of the floor plans in comparison to the sales brochure reveals that the stated living area is 3.2 m² smaller than the one sold. The difference in the purchase price amounts to approximately CHF 68,000. Had the buyer not carried out this comparison, this defect would never have come to light.
Practical example 2: Turnkey single-family house in Aargau
A couple took possession of their new house from a general contractor. The initial inspection went smoothly. Three years later, moisture damage appeared in the basement. An investigation revealed that the foundation waterproofing did not meet standards. Since the warranty period was still valid and the defect was reported in a timely manner, the contractor covered the remediation costs of approximately CHF 35,000. This case illustrates the importance of detecting hidden defects and the need for ongoing monitoring during the warranty period.
Practical example 3: Architectural building in the Bern region
A homeowner had his house built by an architect and various contractors. During the final inspection, an independent expert was called in who, upon examining the construction details, discovered that a crucial facade connection did not meet applicable standards. The defect was documented, and the necessary repairs were carried out under warranty. Had the homeowner conducted the final inspection alone, the detail would likely have gone unnoticed, and subsequent water damage would have been probable.
17. What are the most common typical errors that occur during acceptance testing?
In practice, several recurring errors can be observed that occur regardless of the construction type and contract type.
Signing under time pressure:
Buyers often feel pressured to complete the handover in one day. However, the handover can be extended or postponed. If you are unsure, do not sign.
Accept verbal agreements:
Statements like "we'll look into that" have no legal standing. Anything not included in the minutes is not agreed upon.
Do not immediately report defects in writing:
Visible defects must be recorded directly in the protocol, otherwise they will be considered approved.
Lose weight without comparing it to plans:
Those who do not compare the built structure with the plans cannot detect deviations in areas, heights, and constructions.
Documenting without photos:
Every defect should be documented with a photo, date, and precise location. In case of a dispute, this is the most important basis of evidence.
Do not check hidden areas:
Shafts, cavities, installations, and connections are often no longer accessible after handover. A final inspection before closing these areas is often no longer possible.
18. What should you, as the buyer, pay attention to after acceptance?
Acceptance is not the end, but the beginning of the warranty period. The first few years are crucial in determining whether hidden defects are detected and reported in time.
Recommended steps after acceptance:
Keep all documents (contract, plans, building description, minutes) systematically.
Record any unusual observations continuously, including the date and a photo, even if they are initially unclear.
Check critical areas (roof, facade, balcony, basement) after the first winter and after heavy rain.
Pay particular attention to any newly appearing cracks, moisture, or odors during the first two years.
Actively plan for the 2-year and 5-year warranty purchases.
Document your complaints in writing and with proof of delivery.
An individual warranty and maintenance document helps keep track of deadlines over ten years and prevents claims from being lost due to lapse of time. raumwert plus creates such a document based on the specific contract and legal requirements for each project it manages.
19. Frequently Asked Questions about Apartment and House Handover
What legal changes occur the moment you sign the acceptance protocol? With acceptance, the transfer of risk takes place; from this point on, any damages are the buyer's responsibility. The warranty periods begin, usually two and five years, and up to ten years for latent defects. Visible defects must be reported immediately; otherwise, they are considered accepted, and the final payment typically becomes due.
Do you have to sign at the acceptance inspection if you're unsure? No. Acceptance inspections can be extended or postponed, and anyone who is unsure should not sign. Don't rely on verbal agreements either, because anything not recorded in the minutes is not legally binding.
Can you refuse acceptance of a defective work? According to Article 368 of the Swiss Code of Obligations (OR), the client is entitled to refuse acceptance of a defective work if the defects are so significant that the work is unusable for them or cannot reasonably be expected to be accepted. In this case, the risk does not transfer, the warranty periods do not begin, and the final payment is not due. Refusal is a powerful tool; it should be justified in writing and clearly describe the essential defects.
How much time before the official inspection should a preliminary inspection take place? The preliminary inspection usually takes place two to four weeks before the official inspection. It has no direct legal effect, but gives the contractor time to make corrections before signing. It is particularly useful if you anticipate many outstanding issues or if complex technical systems need to be inspected.
Why is a simple on-site inspection insufficient for a complete acceptance inspection? A complete acceptance inspection operates on three levels. In addition to the on-site inspection, it includes comparing the constructed work with the construction contract, building specifications, and sample lists, as well as comparing the execution with the construction plans and applicable standards. Levels 2 and 3 are generally not offered as standard practice by client representatives in Switzerland, even though these are precisely where costly construction defects and incorrect workmanship can be identified.
Are you allowed to withhold part of the final payment until defects are remedied? Yes. You may withhold a reasonable portion of the final payment until the defects are rectified. In addition, after a properly submitted complaint, you are entitled to rectification, a price reduction, rescission of the contract, and compensation for damages in the case of defects caused by the seller.
