Technical and legal framework
This service sits within a framework of statutory duties, technical rulebooks and operational practice. The distinction matters because it determines who is responsible for what.
- Who is responsible
- The cleaning obligation falls on the operator of the property: as owner under the duty of care towards persons on the premises, as employer under occupational health and safety law. The cleaning contract organises this obligation, it does not transfer it. However complete the contract, it does not release the client from responsibility for the safety of their premises.
- Type of contract
- Ongoing routine cleaning is mainly handled as a contract for services: what is owed is the activity at the agreed frequency and quality, not a guaranteed end condition. Deep or post-construction cleaning with a defined result, by contrast, is regularly described as a contract for work. What is enforceable in a complaint depends on this classification.
- Occupational health and safety
- Towards the cleaning staff, the contractor is the employer and therefore responsible for the instruction and risk assessment of its own staff. The client remains responsible for the hazards that their property brings with it: access routes, lighting, electrical installations, escape routes and the handling of their own systems. Property documentation must therefore be mutual.
- Hygiene
- The German Infection Protection Act obliges certain establishments – such as medical practices and care facilities – to meet hygiene requirements. For an ordinary office building it provides no legal basis for disinfection services. Anyone who puts disinfection out to tender should justify it on hygiene grounds, not with a law that does not apply here.
- DIN 77400
- A standard, not a rule of law. Its purpose is to make cleaning services describable and verifiable – exactly the function that the schedule of services fulfils. It becomes binding through contract, legal reference or presumption effect, not through itself. Professional review of the standard in its full text is required.
The rulebooks named here describe requirements for how the work is carried out – they are not a certification held by BREREI. VDI and DIN normative texts are chargeable and were not available in full; where a statement touches the normative detail, this is noted in place.
