Ventilation and hoods in foodservice: rules
Which ventilation requirements come from regulations and which from practice. Duct cleaning deadlines, neighbour complaints and cost split in a lease.
Ventilation comes back to you twice. When you take over the premises and wonder whether that hood will be enough. And when the neighbour on the first floor writes a complaint because his living room smells of your kitchen. Some of the requirements really are in the regulations. Others, including most of the hood cleaning frequencies circulating online, have no basis in any standard. This text separates the one from the other.
Key points at a glance
- Food law gives no numbers. Regulation (EC) No 852/2004 requires "suitable and sufficient" ventilation. The inspector judges this by its effects: condensation, grease, smell.
- The hard deadlines are in the fire safety regulations, not the sanitary ones. You clean ventilation ducts at least once a year. "Once a month" applies to smoke and flue ducts from hearths, not to the extraction duct.
- The frequency of washing grease filters and the hood does not follow from any regulation. You set it yourself, in the hygiene plan.
- In a rented premises the statutory duty lies with the building owner, but the cost usually falls on you. The lease decides, not the statute.
Why the inspector cares about ventilation: hygiene, not comfort
The Sanepid (the State Sanitary Inspection) inspector does not check whether your cooks are warm. They check whether the air contaminates the food.
The basis is Regulation (EC) No 852/2004, Annex II, Chapter I, point 5: "There must be suitable and sufficient means of natural or mechanical ventilation. Mechanical airflow from contaminated areas to clean areas must be avoided." The same provision requires easy access to filters. The obligation to apply it is placed on you by Art. 59(1) of the Act on Food and Nutrition Safety (25 August 2006).
The inspector reads this together with Chapter II, point 1(c), under which ceilings and overhead fixtures are to avoid accumulating dirt and to reduce condensation and mould growth. The hood and the visible duct are exactly overhead fixtures. Steam on the ceiling, a drop of grease on the edge of the hood and the smell of frying in the dining room are, for the inspector, evidence that ventilation is insufficient. They do not need an anemometer.
Requirements for a venue with heat treatment
How many air changes per hour must a commercial kitchen have? The regulations do not specify. The technical conditions for buildings, in § 147, require an appropriate quality of the indoor environment and refer to Polish Standards, and the figure of 20 m³/h per person in § 149 applies to dwellings, not to a commercial kitchen. The capacity is determined by the installation design, calculated from the output of the heating appliances. Designers reach for the PN-EN 16282 series of standards, but under Art. 5(3) of the Standardisation Act the use of Polish Standards is in principle voluntary.
What you must have regardless of the numbers: mechanical extraction above every heat-treatment station with grease filters, make-up air (without it the hood has nothing to extract), airflow from clean zones to dirty ones, and ventilation of the sanitary facilities, required explicitly in Chapter I, point 6. The technical conditions permit recirculation only where the purpose of the room does not involve the emission of harmful substances or disease-causing bacteria. We collected the rest in the full list of sanitary requirements for a foodservice business.
Hood, filters, ducts: cleaning frequency and who does it
The most important distinction on this topic: a ventilation duct is not the same as a smoke duct. The extraction duct above a frying pan is a ventilation duct. The chimney from a wood-fired oven or from a gas hearth is a smoke or flue duct. The deadlines below come from § 34 of the Ministry of the Interior and Administration regulation of 7 June 2010 on the fire protection of buildings.
| Element | Who does it | How often | How to document it |
|---|---|---|---|
| Hood grease filters | kitchen staff | no legal standard, per the manufacturer and the hygiene plan | cleaning and disinfection register |
| Hood: interior and casing | staff or an external company | no legal standard, own schedule | cleaning and disinfection register |
| Ventilation ducts (extraction ducts) | person with chimney sweep qualifications | at least once a year, more often if the conditions of use require it | chimney sweep protocol |
| Smoke and flue ducts from foodservice hearths | person with chimney sweep qualifications | at least once a month, unless local regulations provide otherwise | chimney sweep protocol |
| Periodic inspection of chimney ducts and the gas installation | master chimney sweep or person with construction licences | at least once a year (Art. 62 of the Construction Law) | periodic inspection protocol |
Mind the last row. With forced-draught ventilation driven by mechanical devices, the periodic inspection is carried out by a person with construction licences, not by a master chimney sweep. When ordering the service, say plainly that you have mechanical extraction.
For filters and the hood, the basis is Annex II, Chapter V of Regulation 852/2004: equipment is to be cleaned "at a frequency sufficient to avoid any risk of contamination". You set the frequency, and with daily frying a weekly filter-washing cycle will be hard to defend. We described how to build the schedule in the text on the cleaning and disinfection procedure that works in real life.
Inspection documentation as part of the hygiene plan
The chimney sweep protocol usually sits in the technical binder, and the hygiene plan in the kitchen. That is a mistake, because the inspector asks about both in the same conversation. Keep copies of the protocols together with the GHP (Good Hygiene Practice) and GMP (Good Manufacturing Practice) documentation on your premises.
Neighbour complaints: who turns up and what they look for
Noise. Since 23 September 2021, noise measurements and the decision under Art. 115a of the Environmental Protection Law belong to the starosta (head of the county), and in cities with county rights to the city mayor. The Voivodeship Inspectorate for Environmental Protection (WIOŚ) measures emissions on the grounds of businesses that already have such a decision. A complaint about a fan in the courtyard therefore goes first to the office, not to WIOŚ.
Smell. Poland has no odour act and no odour standards. That does not mean impunity. A neighbour can go to civil court under Art. 144 of the Civil Code, which prohibits disturbing the use of neighbouring properties beyond the average measure. Cases about taking the exhaust outlet above the roof end up exactly there.
Technical condition and legality. The building supervision authority will check the efficiency of the ducts and whether the periodic inspections were carried out. It will also check whether you were allowed to do what you did at all. If the premises was a shop and you started heat treatment, the hygiene, sanitary and fire conditions have changed. That is a change of use of the premises under Art. 71 of the Construction Law, which requires notification.
Sanepid. A neighbour's complaint is one of the more frequent sources of an inspection outside the schedule, and the inspector, once on site, will not limit themselves to ventilation. We described the preparation in the text on an unannounced Sanepid inspection.
Ventilation in rented premises: whose problem it is under the lease
This is where most venues lose, because nobody settled it before the lease was signed.
The starting point from the statute. The duty of periodic inspections under Art. 62 of the Construction Law rests on the owner or manager of the building, not on the tenant. If the building supervision authority finds that the annual inspection of chimney ducts is missing, the addressee will be the building owner or the owners' association.
The starting point from the Civil Code. Art. 662 § 1 requires the landlord to hand over the thing in a condition fit for the agreed use and to maintain it in that condition throughout the lease. If the lease says the premises is let for foodservice, working ventilation is part of that use. Art. 662 § 2 shifts to the tenant only minor expenses connected with the ordinary use of the thing.
And this is where the line of dispute runs. Washing filters is a minor expense, that is, your cost. Replacing a roof fan or taking the duct above the roof of a tenement building is not a minor expense. The annual cleaning of ducts and the chimney sweep inspection sit in the middle, and that is why they are the most common flashpoint.
What the lease usually does. Standard commercial lease templates shift to the tenant "all inspections of installations in the premises". Such a clause does not remove from the owner the public-law obligation under the Construction Law, because that cannot be transferred by contract. It does, however, effectively shift the cost and the organisation to you. The owner still answers to the building supervision authority, and you pay and arrange the chimney sweep.
Settle four things before signing and write them down explicitly:
- Where the premises end and the shared installation begins. The hood and the section of duct in the premises are one thing. The riser through four floors and the outlet on the roof are part of the common property. Without this boundary every repair is a negotiation from zero.
- Who orders and who pays for the cleaning and the inspection. A working model: the tenant takes the section in the premises, the owner takes the riser and the outlet, and both sides exchange protocols.
- Who supplies the protocols and by when. If the manager orders the inspection, you need a copy for your GHP documentation. Write down a deadline, for example fourteen days from completion. Without it you will be asking for a document that Sanepid expects from you.
- Who finances the upgrade if the duct cannot cope with your kitchen. Where the lease is silent and the landlord does not act, Art. 663 of the Civil Code lets you set them a reasonable deadline for repairs that fall on them and, after the deadline passes without result, carry them out at their cost. Take over the premises with a protocol recording the state of the installation, because without it it is hard to prove what you found.
The remaining clauses that decide acceptance are collected in the text on lease agreement clauses for a foodservice premises.
What to write in the hygiene plan to close the topic
- "Hood grease filters": frequency, responsible person, cleaning agent, where the register entry is made.
- "Hood and surfaces above the heating line": a separate frequency, usually less frequent than for the filters.
- "Cleaning of extraction ducts": external contractor, at least once a year, where the protocol is kept.
- Corrective action for condensation or smell in the dining room: switching off the station, reporting to the landlord, an entry in the non-conformity register.
Frequently asked questions
How often does a hood in a restaurant need cleaning?
No regulation gives a cleaning frequency for the hood or grease filters. Regulation 852/2004 requires equipment to be cleaned "at a frequency sufficient to avoid any risk of contamination", so you set it yourself in the hygiene plan, based on the manufacturer's instructions and the load on the kitchen. The ducts themselves are different: those you clean at least once a year.
Do ventilation ducts in a foodservice business have to be cleaned once a month?
No. The "at least once a month" deadline from § 34 of the regulation on the fire protection of buildings applies to smoke and flue ducts from the hearths of mass catering businesses, not to extraction ducts. For ventilation ducts the regulation provides for cleaning at least once a year, unless more frequent cleaning results from the conditions of use.
How many air changes must a commercial kitchen have?
The generally applicable regulations give no such number. The technical conditions refer to Polish Standards, and the 20 m³/h per person given there applies to dwellings. The capacity follows from the installation design calculated from the output of the heating appliances. Designers use the PN-EN 16282 series of standards, but the use of Polish Standards is in principle voluntary.
Who is responsible for ventilation in rented premises?
The duty of annual inspections of chimney ducts under Art. 62 of the Construction Law rests on the owner or manager of the building and cannot be transferred by contract. Art. 662 § 1 of the Civil Code requires the landlord to maintain the premises in a condition fit for the agreed use, and § 2 shifts to the tenant minor expenses connected with ordinary use, which includes washing filters. The split of the cost of cleaning the ducts is decided by the lease.
