Cold Storage in Switzerland: Requirements & Regulations

What makes cold storage spaces unique as commercial properties?

Unlike classic warehouse or commercial spaces, cold storage facilities must reliably and permanently guarantee specific climatic conditions. This concerns not only the temperature itself, but also humidity, air circulation, and the avoidance of temperature fluctuations during loading and unloading. For companies in the food sector, pharmaceutical industry, or retail, choosing the right space is therefore not just a matter of location, but a question of legal compliance and product safety. In the worst-case scenario, an unsuitable property can lead to product loss, regulatory complaints, or even the withdrawal of operating licenses.

Particularly in Switzerland, where quality standards are traditionally high, it is advisable to coordinate early with specialist planners, the responsible cantonal food authority, or, in the case of pharmaceutical products, Swissmedic to clarify which structural and organizational requirements must be met.

Cold storage requirements in Switzerland: The legal framework

Cold storage requirements in Switzerland are primarily derived from the Food Safety Act (LMG) and the associated Food and Utility Articles Ordinance (LGV). These demand that food products be stored in a way that guarantees their quality and safety throughout the entire storage period. Businesses that store, process, or distribute food must also maintain a self-monitoring system based on HACCP (Hazard Analysis and Critical Control Points) principles. This system documents critical control points such as temperature deviations, cleaning intervals, and pest control.

Enforcement falls under the jurisdiction of the cantonal food control authorities, which is why there may be slight differences in licensing procedures and inspection intervals depending on the canton. Before renting cold storage space, it is therefore always worth consulting with the responsible cantonal food inspectorate, especially if a change of use or renovation is planned.

Structural minimum requirements

The minimum structural requirements include seamless thermal insulation, easy-to-clean surfaces (usually stainless steel or coated panels), functional drainage systems to prevent condensation, and airlocks or anterooms that allow doors to close quickly during goods handling. Lighting and accessibility for cleaning and maintenance work are also part of the inspection criteria.

Deep-freeze warehouse regulations for food products

Regarding deep-freeze warehouse regulations for food products, maintaining the cold chain is the central focus. Deep-frozen products must generally be stored continuously at -18°C or colder, though short-term, documented fluctuations during goods handling are tolerated, provided they do not compromise product quality. The LGV also requires clear labeling of the storage temperature as well as regular, traceable temperature monitoring, typically using automated data loggers.

Batch or lot traceability is also crucial: in the event of a recall, it must be possible to trace at any time which goods were stored when, where, and at what temperature. Businesses storing deep-frozen goods on a larger scale therefore require an effective warehouse management system that ideally integrates directly with the property's cooling technology.

For tenants, this means: before signing a lease, you should check whether the existing refrigeration system reliably reaches the required temperatures and whether an emergency power generator or at least an alarm system in the event of a power outage is available. A total failure of the cooling system can lead to complete loss of inventory within a few hours.

Cold storage requirements for pharma: Heightened duty of care

The requirements for pharmaceutical cold storage are even stricter. Medicines and medical products are subject to the Good Distribution Practice (GDP) guidelines, which regulate storage, transport, and documentation across the entire supply chain. In Switzerland, Swissmedic is responsible for monitoring, with many requirements closely aligned with international standards such as the WHO GDP guidelines.

Pharmaceutical products are often stored between 2 and 8°C (fridge temperature) or at controlled room temperature (15 to 25°C). Crucially, the refrigeration system used must be validated, meaning that measurements and qualification protocols must prove that the temperature remains homogeneous throughout the entire storage room, even in potential hotspots near doors or ventilation outlets.

Anyone wishing to rent space for pharmaceutical storage should therefore clarify early on whether a mapping study can be conducted and whether the infrastructure supports redundant cooling systems as well as 24/7 alarm management. Close coordination with your own quality assurance department and, if necessary, legal advice are essential here, as violations of GDP guidelines can have severe consequences for your operating license.

Commercial refrigeration systems in Switzerland: Technology, energy, and the environment

The technical backbone of any cold storage space is its commercial refrigeration system, which must be both highly efficient and powerful. Since refrigeration systems are among the largest energy consumers in commercial properties, it is well worth checking the manufacturing year, the type of refrigerant used, and the maintenance history of the system before renting a space.

Since the revision of the Chemical Risk Reduction Ordinance (ChemRRV), climate-damaging refrigerants with high global warming potential (GWP) are being gradually phased out. Consequently, new installations increasingly rely on natural refrigerants such as ammonia, CO2, or propane. This can be highly relevant for tenants, as older systems running on phased-out refrigerants will become more expensive to maintain or will need to be replaced entirely in the future.

Energy efficiency is also playing an increasingly vital role, not least due to rising electricity prices. Modern refrigeration systems featuring heat recovery, frequency-controlled compressors, and high-quality insulation can significantly reduce operating costs. Before signing a contract, it is highly recommended to review the average energy costs from recent years in order to calculate realistic service charges on account.

What to consider when renting a cold storage space

Alongside regulatory and technical aspects, there are several practical points to consider during viewings and lease negotiations. These include the clear ceiling height for your planned storage logistics, floor load capacity for high-bay warehouses, the number and size of loading docks, and accessibility for heavy goods vehicles (HGVs). The option to establish multiple temperature zones within the same property can also be a decisive factor for businesses handling diverse product categories.

In commercial tenancy law, cold storage spaces are generally subject to the same provisions as other business leases under Art. 253 et seq. of the Swiss Code of Obligations (CO). However, a clear contractual agreement is particularly crucial for the following points:

• Who bears the costs for maintenance, repair, and potential replacement of the refrigeration system?
• How are the energy-intensive service charges on account billed, and who has access to the actual consumption data?
• Are there contractual assurances regarding guaranteed temperature ranges and liability in the event of system failures?
• What structural modifications is the tenant permitted to make, and who bears the reinstatement costs when moving out?

Since these issues can be highly complex depending on the individual case, it is advisable for larger investments or long-term lease agreements to seek counsel from a commercial tenancy law expert or a specialist in food or pharmaceutical regulatory compliance.

Conclusion: Checklist for your cold storage project

Cold storage spaces are a highly specialized type of commercial property where legal requirements, technical specifications, and financial considerations are closely intertwined. By understanding the relevant regulations early on, conducting a technical audit of the refrigeration systems, and clearly structuring the lease terms, you can establish a solid foundation for your operations. The following checklist summarizes the key aspects:

1. Clarification of the applicable cold storage requirements in Switzerland with the competent cantonal authority
2. Evaluation of the temperature zones and suitability for deep-frozen goods or pharmaceutical products
3. Technical assessment of the existing refrigeration system, including refrigerant type and energy efficiency
4. Contractual definition of maintenance responsibilities, service charges, and liability in case of system failure
5. Inspection of the physical infrastructure, including loading docks, ceiling heights, and heavy-vehicle access

Taking this approach significantly reduces the risk of product spoilage, regulatory issues, or unexpected additional costs.
