Commercial kitchens in Abu Dhabi: design rules and the maintenance that keeps them compliant

Updated 16 October 2026. Every rule in this guide links to its official source at the end of the page.

Key facts

• The guideline: ADAFSA Guideline No. (6) of 2019, Food Service Design and Equipment, applies to food service, including restaurants, self-service and takeaway, permanent or temporary, for new and existing establishments.
• Plans first: before building or renovation starts, plans drawn to scale, such as 1:50 floor plans, sectional elevations with equipment, and mechanical exhaust ventilation drawings, can be consulted by ADAFSA.
• Hoods: ceiling-mounted hoods with separately vented exhaust fans extending over all cooking equipment help remove odours, smoke, moisture and fumes, and must stop grease and condensation dripping onto food.
• Air balance: the guideline says overall facility air balance should be slightly positive, while the kitchen can have slight negative pressure to keep odours in.
• Grease traps and drains: grease traps, if used, should be easily accessible for cleaning; plumbing must be watertight with adequate traps and vents and sized for peak loads.
• Lighting: at least 540 lux at food working surfaces, 220 lux in work rooms and similar areas, and 110 lux in walk-in cold rooms and dry stores.

Why kitchen design is a maintenance decision

ADAFSA's Guideline No. (6) of 2019, Food Service Design and Equipment, opens with a principle every restaurant owner learns the expensive way: food safety begins at the earliest planning stages, and the correct design produces a food business that is easy to clean and maintain. The guideline notes that there are cost advantages in installing features that support food safety at the time of construction, rather than adding them later.

The guideline is written for food business operators, architects, designers, builders and other professionals involved in designing and building food establishments, for new and existing premises. It covers food service, which it defines as food and beverage serving activities providing complete meals or drinks fit for immediate consumption, in traditional restaurants, self-service or takeaway, permanent or temporary, with or without seating. It represents ADAFSA's advice, and states that operators can use an equivalent approach if it satisfies the applicable legislation. It also notes that other competent authorities may need to provide input or approvals depending on the type of establishment.

For anyone maintaining a kitchen, the guideline is useful in a second way: it describes how each system should work, which is the standard maintenance should keep it at. This page follows it system by system. For wider Abu Dhabi maintenance rules, see the Abu Dhabi maintenance guide; for food retail pest rules, see the Abu Dhabi pest control guide.

The plans ADAFSA can consult before you build

The guideline says that when designing, building or fitting out a new food establishment, or changing an existing one, the first step is developing or obtaining plans, so the proposal can be assessed before building starts, which saves time and money. Before building or renovation starts, copies of plans drawn to scale can be consulted by ADAFSA, including:

The guideline makes the point that what you plan to serve has a major impact on layout, facilities and equipment. For maintenance, the mechanical exhaust drawings matter most later: they show where ducts run, where access panels must be, and where the fan sits, which is exactly what a kitchen exhaust cleaning team needs to reach.

Workflow and space: designing out cross-contamination

The guideline asks for a design that prevents food safety hazards, separates operations that may cause cross-contamination, provides a hygienic workflow from receipt to storage, preparation, cooking and serving, protects against pest access and infestation, and easily allows sufficient maintenance and cleaning. It describes an assembly-line concept: a continuous flow of receiving, storing, preparing, cooking and serving, minimising traffic lines, backtracking and cross traffic, with the direction reversing after service to remove soiled dishes and trash.

On space, the guideline asks for adequate storage, hot, cold and dry, separated from chemical storage, toilets, waste storage and offices, and enough working space to minimise airborne contamination and allow freedom of movement. One line is directly about maintenance: there should be sufficient space between equipment, floors and walls to move equipment and reach the floor beneath and the walls beside it for cleaning. A kitchen where the fryer cannot be pulled out is a kitchen where grease builds up behind it.

The guideline also describes work areas in detail, for example pot wash next to the hot and cold kitchen, ideally with one way in and one way out for garbage, and dishwashing areas that are well ventilated, not in a main passageway, and arranged so soiled dishes do not cross through work units, with a smooth flow through sorting, scraping, washing, rinsing, drying and storage.

Questions to answer before you design

The guideline lists questions to settle when planning a food establishment, because the answers drive the layout, equipment and finishes, and therefore the maintenance load for years:

For maintenance, the hours question is the one most often underestimated: a kitchen running long hours wears finishes, door closers, refrigeration and exhaust fans much faster, and needs maintenance windows planned into its schedule from the start.

Receiving, storage, staff areas and toilets

The guideline describes seven major types of work in food service: receiving; storing dry, refrigerated and frozen food; preparation; cooking; serving; ware washing; and supporting services such as administration, lockers, rest rooms and storage. Several of its work-area points are directly about building systems:

• Separate entrances: a separate staff entrance and exit, not the same as the entrance for food deliveries or for garbage disposal.
• Receiving: an air-conditioned receiving area with an outside platform or loading dock, preferably covered, and floor space to check deliveries; a de-boxing area is preferred because it helps prevent contamination and pest infestation; where necessary, a separate vegetable cleaning room with a vegetable fridge next to receiving.
• Hygiene at entry points: where necessary, entry and exit points equipped for cleaning and disinfecting vehicle wheels, and building entry points equipped with cleaning materials and footwear disinfection.
• Door sizes: the exterior door wide enough for trucks, large cartons and any large equipment to be installed in the kitchen.
• Storage: close to the delivery entrance, with chilled storage separated in large kitchens into vegetables, fish and meat, freezers, dry stores, a stewarding store for cleaning equipment and reserves of china, linen and uniforms, and a chemical store kept separate and apart from all food.
• Dressing rooms and lockers: separate from food preparation, storage, service and utensil areas where staff change clothes, with lockers for personal belongings.
• Toilets: conveniently located, so patrons do not pass through food preparation, storage or utensil washing areas; completely enclosed with tight-fitting, self-closing solid doors; adequately ventilated and connected to effective drainage; not opening directly into food handling areas; with easily cleanable fixtures and hand wash sinks inside.

Each of these is also a maintenance list: dock levellers and receiving doors, cold room doors and gaskets, toilet extract fans and door closers, locker room ventilation and drains. Power Zone's teams maintain them alongside the kitchen itself, including AC servicing for air-conditioned receiving and preparation rooms.

Bakery and pastry areas

The guideline treats bakery and pastry as a fairly independent unit that may be separated from other preparation areas. It should be a closed, air-conditioned, temperature-controlled room, with the pastry chiller and freezer adjacent and, where necessary, a pastry pot wash with sufficient shelving. Work and equipment are best routed in a counter-clockwise arrangement with the finished product closest to the serving unit, so tasks run in a direct line without backtracking. If frozen desserts or chocolate are made on site rather than bought, the guideline calls for a separate room with specialised equipment. For maintenance, pastry rooms depend on stable temperature: AC units and refrigeration serving them need preventive servicing before the hot months, and door seals kept intact.

Preparation and cooking areas

The guideline describes how preparation and cooking units relate to each other, and several points shape what maintenance teams later deal with:

• Cold kitchen: ideally a closed room with temperature control, near the refrigerated vegetable store and the cooking and salad areas.
• Butchery: separate rooms or areas for meat, fish and poultry, with butcher blocks, grinders, sinks, storage trays and chillers, and a thawing unit when needed.
• Main cooking unit: the hub of the kitchen, usually in or near the centre, most efficient next to vegetable preparation, the stores, the hot kitchen chiller, the blast chiller and the dairy chiller, and ideally behind or near the serving area.
• Steam equipment: usually installed together in a row, with the appropriate floor drains in front.
• Short-order cooking: grills and broilers closest to the serving unit.

Grouping steam equipment over a line of floor drains, and keeping chillers and blast chillers next to the cooking unit, also concentrates the services that need the most maintenance in one zone: drains that must stay clear, condensate and refrigeration lines, and the hood above. Planning access to that zone, and to the condensing units that serve the chillers, makes every future service visit shorter.

Hotels, hospitals and multi-floor kitchens

The guideline covers settings beyond the classic restaurant. It notes that mobile refrigerated units are available for banquets, special parties and other uses such as hospitals, so set-up salads can be refrigerated until mealtime and moved directly to the dining area; that a refrigerated table is convenient for holding salad ingredients during short-order preparation; and that in hospitals, nursing homes or restaurants on more than one floor, easy access to service lifts or dumbwaiters lets prepared food be delivered in safe condition. It also describes a service area separated from the kitchen, with the coffee machine and linen storage, and, where necessary, a chef's office or EHS office to keep records and files of the food safety management system, and a stewarding office. For maintenance, mobile refrigerated units, service lifts and refrigeration spread over several floors all add items to the plan; a service lift that fails at peak time can stop food service across a building. Power Zone provides lift maintenance alongside kitchen systems.

Hoods, exhaust and ventilation

The guideline describes ceiling-mounted hoods with separately vented exhaust fans, extending over all cooking equipment, as helping ventilate the kitchen by removing odours, smoke, moisture and fumes. Its ventilation section adds that all food establishments shall be adequately ventilated to prevent excessive heat, steam, condensation, vapours, smoke and fumes, and that ventilation systems should be designed and constructed so that:

• airborne contamination from aerosols and condensation droplets is minimised;
• ambient temperatures and humidity are controlled;
• air does not flow from contaminated areas, such as toilets and dressing areas, to clean areas such as ready-to-eat food handling;
• toilets, laundries and living areas are separated from areas handling exposed food by airlocks or self-closing doors;
• drains, grease traps and ventilation pipes are sealed, and mesh screens are installed at opening windows and other ventilation openings;
• overall facility air balance is slightly positive, while the kitchen can have slight negative pressure to keep odours from leaving it;
• hoods and ventilation devices are built and installed to prevent grease or condensation from collecting on walls or ceilings and dripping into food or onto food-contact surfaces.

The guideline also asks that over-shelves above cooking equipment do not interfere with hood function. All of this describes a system that works only while it is clean. Grease-loaded filters reduce extraction; grease inside ducts is a fire load; a failing exhaust fan or a blocked make-up air path changes the pressure balance so odours and heat spill into the dining area. A maintenance programme, offered here as guidance, typically includes:

Power Zone provides kitchen hood, exhaust duct and ecology unit cleaning and maintenance and kitchen filter supply and replacement.

Grease traps, drains and wastewater

The guideline's sewage and wastewater section asks for drainage and waste disposal systems that avoid any risk of contaminating food or the potable water supply: adequately sized and designed, properly installed and maintained, designed so open channels do not carry waste towards or into clean areas, especially where high-risk food is handled, and located so wastewater cannot pollute the water supply or contaminate food. It states that grease traps, if used, should be located so they are easily accessible for cleaning and pose no risk to food safety.

Its plumbing section adds more detail that maintenance teams meet every day:

• all plumbing and waste lines, including sewer lines, large enough to carry peak loads, watertight, with adequate traps and vents;
• each compartment of a multi-compartment sink draining independently to a properly sized floor sink through an air gap;
• all floor sinks accessible for cleaning and inspection, and trench drains sloped to drain;
• dishwasher waste lines indirect, except where next to a trapped floor drain, where they may connect upstream of the trap;
• pipes and conduit outside walls installed with enough space to clean between them and the wall;
• plumbing and the manner of waste disposal approved by the competent authority.

The maintenance lesson is that a grease trap placed under a prep table or behind a cold room, with no clear access, is a trap that will not be cleaned on time. Planned emptying, at a frequency set by the trap size and the kitchen's output, protects the drains downstream; dosing systems can help between cleans but do not replace emptying. Power Zone provides grease trap installation, cleaning and maintenance, grease dosing systems and drain cleaning.

Water supply, backflow and hand washing

The guideline defines potable water as drinking water that is pure and healthy at the point of use and meets the technical regulations of the national standard-setting agency and the local regulatory and supervisory bureau. It asks for backflow prevention on equipment plumbed to a water line, listing ice machines, drink dispensers, soda fountain carbonators, dishwashers, chemical dispensers, steamers and carbon filters, and for equipment to be protected against cross connections between water supply and waste.

For maintenance, backflow devices and water filters are the easy items to forget: they need periodic checking and cartridge changes, and the water heater serving hand basins must keep water warm. Power Zone provides plumbing fixture repairs, water filtration and water heater maintenance.

Electrical installations in kitchens

The guideline's electrical section is short but practical. Electrical lines should be concealed within the building structure as far as possible, or encased in sealed containment. Where conduit cannot be concealed, for example on block walls during a remodel, runs should be kept away from walls and ceilings and off the floor, and exposed horizontal runs avoided because they collect dust and debris and are often neglected by cleaners for fear of being shocked. Where conduit or pipes enter a wall, ceiling or floor, the opening should be tightly sealed to remove pest hiding places and passageways. For occupational safety, extension cords, conduit and pipes should not be installed across passages, traffic areas or door openings.

In a working kitchen, add the realities of heat, moisture and grease: socket outlets and isolators near wet areas need suitable protection and enclosures, equipment circuits need protection devices that are tested, and burnt or melted plugs on fryers, ovens and dishwashers are warnings, not cosmetic issues. Power Zone provides panel, circuit and safety device maintenance and electrical repairs.

Lighting levels the guideline sets

The guideline is one of the few documents that gives numbers. It says lighting should not alter colours, and that intensity should not be less than:

It also requires light fixtures and wiring protected for easy cleaning and to prevent cross-contamination, and lighting shielded over equipment holding or displaying food, in walk-in fridges and freezers, and over areas where food or food-contact surfaces are exposed. For maintenance, failed lamps in a cold room or over a prep bench take a kitchen below these levels quietly; a periodic check with a light meter, and replacement of failed or discoloured fittings with suitable shielded fittings, keeps it compliant. Power Zone provides lighting installation and maintenance.

Floors, walls, ceilings, doors and windows

These finishes degrade with use: cracked floor tiles and failed cove joints hold water and dirt, damaged ceiling panels shed particles and open voids for pests, door closers fail and leave doors propped open. Repairing them promptly keeps the kitchen at the standard it was designed to. Power Zone provides tiling and grouting, ceiling works, doors and windows and steel fabrication.

Equipment: mobility, materials and dishwashing

• Mobility: heavy or large equipment that is not readily movable should be mounted on wheels, and equipment arranged for easy access to clean it and the area around it.
• Materials: wood surfaces and wooden cutting boards are not allowed in the food handling area.
• Dishwashing: a three-compartment sink with one sink having heating coils to make water hot enough for disinfection, or a commercial dishwasher, is preferred.
• Separation: a separate preparation area for raw meat, fish and poultry where served; colour-coded or labelled portable cutting boards.
• Protection: food shields on salad bars, with protected glass edges; running water dipping wells for scoops where frozen desserts are portioned.
• Cold and hot holding: equipment used to cook, heat, cool, store or freeze food designed to achieve the required temperatures.

For maintenance, refrigeration is where kitchens lose most money when it fails: condenser coils need cleaning, door gaskets need replacing when torn, and drain lines inside cold rooms need to stay clear so ice and water do not build up. Power Zone's HVAC and cooling maintenance and drain cleaning cover these items.

Garbage areas and waste flow

The guideline says trash and food waste storage is necessary where the building has no disposal facilities. A chilled room near the back entrance may be provided for daily storage of wet garbage where the building has no disposal facilities; the garbage flow should be separated from supplier deliveries and the staff entrance; suitable wash-out capability should be included; and a dry garbage area for boxes and other dry waste provided when needed. It refers to the competent authorities for garbage room specifications. Waste must be disposed of so that it cannot contaminate food and water and cannot offer breeding places for rodents, insects or other vermin. In practice, the garbage room's drain, wash-down point, door closer and screens are maintenance items that decide whether it stays clean or becomes the kitchen's pest source.

A maintenance plan for a running kitchen

The guideline describes how a kitchen should be built. Keeping it there is a schedule, offered here as guidance:

Renovating a kitchen without breaking the design

The guideline applies to changes to existing establishments as well as new ones, and recommends plans before building or renovation starts. Common renovation mistakes, offered here as guidance, are: moving cooking equipment out from under the hood; adding a fryer or grill without checking hood coverage and exhaust capacity; placing new equipment so tight that it cannot be moved for cleaning; closing access panels to ducts behind new ceilings; and connecting new sinks or machines without backflow protection or an air gap. A pre-works survey against the original drawings, and MEP snagging before reopening, avoids most of these. Power Zone provides complete interior fit-out and architectural and MEP snagging inspections.
