The Smoke-Free (Premises & Enforcement) Regulations of 2006 require that almost all public areas and workplaces, including work vehicles that are enclosed or substantially enclosed and have more than one employee, be smoke-free as of July 1, 2007.
As a result, businesses started putting up smoking areas for those who visit or work on their premises. Smoking shelters must, however, comply with the 2006 Smoke-free (Premises and Enforcement) Regulations.
Only in areas that are not significantly enclosed and have at least 50% open space” around the perimeter is smoking authorised.

What does “enclosed premises” mean ?

Any premises will be labelled as enclosed if they have a ceiling, roof, doors, windows or any passageway that are completely enclosed, whether on a temporary or a permanent basis. This includes tents and marquees as well as solid structures.

In the regulation “roof” includes any fixed or moveable structure or device which is capable of covering all or part of the premises as a roof, including, for example, a canvas awning.

What does “substantially enclosed premises” mean?


When a building has a roof or ceiling but openings in the walls that cover less than half of the perimeter, it is said to be substantially enclosed. More frequently, this is referred to as the 50 per cent rule. The enclosed area should include any additional buildings that act as walls or form the boundary of the site with relation to features that may be opened or closed, such as doors, windows or other features. The law specifies that these must also be included when calculating the enclosed area.

What is the 50% Open Space Rule ?

If 50% of the walls or more are missing then it is legal to smoke in the area.

When at least 50% of the perimeter walls are permanently open and unhindered by any surrounding walls or other materials, a smoking area or shelter with a roof may be used for smoking as long as the adjacent walls, buildings, or other objects do not restrict airflow.

How far can a smoking shelter be from any other obstructions?


There are no legal requirements on how far a smoking shelter should be from any other structure. However, each council may have different limitations. There may be ventilation issues if it’s too close to a building, or you may receive complaints if it is too close to any entranceways or windows. The key issue is whether it prevents proper airflow through the shelter. So all of them should be evaluated in themselves but in most councils, this limit is 1.5 meters.

 

Will residential premises have to go smoke-free?


Common areas including stairwells, hallways, and elevators in residential buildings must be smoke-free.

Only the common areas of the HMO building are covered by the Smoke-Free Legislation. The common areas of an HMO would include any kitchens, baths, or living/dining areas that are used by more than one household, as well as facilities used by residents of more than one home, such as communal kitchens, bathrooms, or laundry rooms in apartment buildings.


The law does not apply to private dwellings. However, if the space is designated for child care or music lessons and is utilised as a workplace, such as a room, it must be smoke-free. Where work is undertaken solely to provide personal care for a person living in the dwelling, to assist with domestic work or to maintain the building, the private dwelling is not considered to be a workplace and is exempt from the smokefree legislation.

Put simply;

  • If a space doesn’t have a roof, smoking is allowed there and no further calculations are required as long as the adjacent walls, buildings, etc. don’t obstruct airflow.
  • It is permitted to smoke in an area if it has a roof and at least 50% of the walls are removed.
  • Smoking is not permitted in areas with roofs and walls that make up more than 50% of the space.

To ensure compliance with the smoke-free regulations, businesses must determine what portion of their smoking area is open and what portion is enclosed.

Calculation Method 1

Closed:
(A+B)x2=(70+35)x2
Total=210
(Window and door openings on facade B are counted as closed since they’re not considered permanent openings.)

Total Perimeter: (70×2)+(35×2)=210
Enclosed/Perimeter x 100= (210/210)x100= 100% Enclosed

So in this example, all surfaces will be considered closed then it does not comply with Smoke Free Legislation and smoking cannot be permitted.

Calculation Method 2

Closed:
(A+B)x2=(70+35)x2
Total=210
(Window and door openings on facade B are counted as closed since they’re not considered permanent openings.)

Total Perimeter: 210 
Total Area (210) -Enclosed Area (210)=Open Space (0)

So in this example, all surfaces will be considered closed then it does not comply with Smoke Free Legislation and smoking cannot be permitted.

Calculation Method 1

Closed:
A+B=7x10x2=140

Total Perimeter: 210
Enclosed/Perimeter x 100=

(140/210)x100= 66% Enclosed

If your smoking area / shelter is more than 50% enclosed then it does not comply with Smoke Free Legislation and smoking cannot be permitted.

Calculation Method 2

Closed:
A+B=7x10x2=140 (Total Enclosed Area)

Total Perimeter: 210
Total Area-Enclosed Area= Open Space  210-140=70 

If the open area is less than the enclosed area, the shelter will not comply with legislation.
As this open area in the example is less than the enclosed area, the shelter would not be compliant.

Calculation Method 1

A+D=10x5x2=100
B+C=5x3x2=30

Total Perimeter: 400

(Enclosed/ Perimeter) x100=

Frequently Asked Questions

Smoke-free legislation applies to premises:

  • The public has access to it. For example; pubs, shopping centres, restaurants, cafes.
  • That is a place of work.
  • Providing education, health or care services.

The term “work” also includes volunteer work, thus if a village hall hosts an event with volunteers working there, it must be smoke-free. It would be both a workplace and a public space if the general public attended.

A place that is covered by a roof or ceiling is known as a smoking shelter or structure. It need not have walls; it could simply be a space with a canopy.
For a more enclosed feeling, the smoking shelter can have back and sides. However, it legally can not be fully enclosed.

Employers may designate a smoking room if the policy prohibits smoking in bedrooms, but it must adhere to the requirements outlined above. The administration will also decide whether guests can smoke in smoking rooms. Staff members are not permitted to use the smoking rooms and they may not be utilised for entertainment. 

Outside areas are not covered by the legislation. To prevent employees and guests from having to enter the building through a smoke-filled hallway, companies may adopt a policy that smoking is not permitted within a specific distance of exterior entrances.
