and Kitchens

Major Changes Part 9 Housing and Small Buildings

On November 2, 2012, Ontario Regulation 332/12 was filed to introduce the new Building Code.

Most of the new Building Code will come into force on Jan. 1, 2014. However, certain requirements will come into force later on Jan. 1, 2015 and Jan. 1, 2017.


The new Building Code substantially improves energy-efficiency requirements and makes Ontario one of the leading jurisdictions in North America for water conservation.


So, what are some of the major changes for home construction or renovation under the 2012 Ontario Building Code?

There were over 700 technical changes, but mostly minor grammatical changes, today we will review the most important for your profession


Site-Built Window, Doors and Skylights, Subsection 9.7.5. Windows that are made on site are now regulated.

Height of handrails above nosing to be not less than 865 mm (old 800 mm) and not more than 965 mm. Smaller range and an increased lowest height of handrail Subsection 9.8.7.


The range of the height of the handrail has been reduced to 865 mm to 965 mm

865


Specific guard requirements for compliance with the climbability provisions of the OBC have been removed, Subsection 9.8.6.However, your guard designs must still be

not climbable. The Province has removed provisions, that a designer could have used to achieve compliance.


The guard detail cannot create a ladder effect making the elements climbable


Exit signs are changing, Subsection 9.9.11. We will still have exit signs, but the familiar red and

white signs will be replaced with a green pictogram and white or lightly tinted graphical symbol.


Smoke Alarm Changes, Subsection 9.10.19. Still required on all floor levels, including the

basement, but now must be installed in each sleeping room,

Sound pattern to be temporal or combination temporal and voice relay,

Provided with a battery as an alternative source of power, 7 hours and 4 minutes sounding,

Mandatory silencing of the alarm capabilities for 10 minutes



Spray-applied polyurethane insulation, Subsection 9.25.4.Where the foam insulation functions as the

vapour barrier, it is required to be sufficiently thick so that condensation will not form on the foam or interior wall surface.

This is applicable to 2lb spray foam, not ½ lb and must be a minimum of 50 mm thick.


Any colour but white/creamy

2 lb medium density spray foam

White/creamy colour

½ lb light density spray foam


The ceramic tile installation prescribed requirements have been deleted from the OBC, Subsection 9.30.2. Now;Set in a mortar bed, orApplied to a sound smooth base with a

suitable adhesiveThis opens the door for use of products

such as Schulter Systems. More on this later in the presentation


Dwellings may be served by a drainless composting toilet, Subsection 9.31.4. Choice of a water closet or drainless composting

toilet.


Electrical storage-type service heaters must have a set storage temperature of 600C, Subsection 9.31.6.To ensure adequate heat to kill any bacteria

(Legionella) that may develop in the water as a result of being stored at low temperatures (200C to 450C)


Furnace will be allowed to be designed for dwellings that are much tighter in terms of building envelope, permitting smaller furnaces sizes, Subsection 9.33.2.

Smaller furnaces =

Efficient heating =

Saving fuel


Carbon Monoxide detectors to be installed on or near the ceiling or at the manufacturer’s recommended height, Subsection 9.33.4.

Previously no requirement for location, but more were ceiling mounted as per the manufacturer’s instructions, why is that important?


Symptoms of Carbon Monoxide Poisoning (1)

Be sure that all members of your family know the symptoms of CO poisoning:

Mild Exposure Flu-like symptoms such as headache, running nose, sore eyes, etc.

Medium Exposure Drowsiness, dizziness, vomiting. The sense of disorientation and confusion

may make it difficult for some victims to make rational decisions like leaving the home or calling for assistance.

Extreme Exposure Unconsciousness, brain damage, death.

Continued Low-level Exposure to CO While this may be not lead to observable symptoms, you should still avoid

such exposure.

(1) CMHC


Stud Wall Reinforcement, Subsection 9.5.2. In addition to providing reinforcement within

wall studs for a water closet to permit the future installation of grab bars, now the same must be built for a shower or bathtub



7.1.5.3. Water Distribution Systems (2) Storm sewage or greywater that is free

of solids and treated to conform to Article 7.7.4.1. is permitted to be used as a water supply for,

(a) water closets,(b) urinals,(c) sub-surface irrigation

Ontario Electrical Safety Code

The objective of the Ontario Electrical Safety Code (OESC);

Is to establish safety standards for the installation and maintenance of electrical equipment.

Ontario Electrical Safety Code

The bottom line: Using a proper design layout of

fixtures, equipment and receptacles will, in part, ensure an essentially safe installation and compliance with the requirements of the OESC.

Ontario Electrical Safety Code - Bathrooms

Receptacles Installed In Bathrooms At least one receptacle is required to be installed

in bathrooms, washrooms, power rooms and ensuites containing a wash basin.

Receptacles installed in bathrooms should be located at least 500 mm from the bathtub or shower stall. However, a one metre distance is preferred. This distance is measured horizontally from the receptacle to the face of the bathtub or shower stall.

There are no other requirements for the number or location of receptacles in bathrooms other than the issue previously noted.


Bathtub Location

Receptacle

Switch

The receptacle and switch located on the stud wall on the right side in this photo are at distance of at least 500 mm from the bathtub location.


Luminaires in Damp or Wet Locations A luminaire may be installed in a shower

or above a bathtub. However, the fixture must be approved

for a wet location and installed as per the manufacturer’s instructions.

Ground fault circuit interrupter (GFCI) protection is not required for the light fixture, unless required by the fixture manufacturer.


The luminaire in this photo has been approved for use in a wet or damp location, such as this shower.

Notice the black ring between the ceiling finish and the white luminaire housing.

This is a gasket so that a tight joint is formed prohibiting moisture from accessing the electrical components.


Wet or damp areas

Is this light fixture permitted in this location?

What are the requirements related to its location?

Ontario Electrical Safety Code - Kitchens

Receptacles in Kitchens The placement or location of receptacles in kitchens

is based on the appliances that could be installed and the usage of the room. For appliances,

One receptacle is required for each refrigerator and

Where a gas supply piping or gas connection outlet has been provided for a gas range, one receptacle is also required. The receptacle for the gas range location must not be more than 130 mm from the floor and near the mid-point of the range location measured along the floor line.


Range receptacle is not required where there is a built-in gas or electric cook top or oven

This duplex receptacle is required when there is space for a free standing range when a gas supply pipe is installed

Gas supply pipe


Receptacles in Kitchens For the proper use of the kitchen, a sufficient

number of receptacles (15A split or 20A T-slot) must be located along the wall behind the counter work surfaces so that no point along the wall is more than 900 mm from a receptacle measured horizontally along the wall line.

Therefore, the location of the receptacles cannot exceed a maximum of 1800 mm apart.


Maximum distance from receptacle to pantry is 1800 mm

Receptacle

Receptacle

If this isolated work surface is less than 300 mm in width a receptacle is not required


Receptacles may be installed face down, under the cabinet, instead of on the wall. This is due to the recent use of glass backsplashes


Receptacles in Kitchens A permanently fixed island counter requires at least one

receptacle when the island is at least 600 mm for the long dimension and 300 mm for the short dimension.

For small islands or when the island has equipment or a sink that covers almost the entire counter space, a receptacle is not required.

Since the receptacle cannot be located in or on the work surface, it must be located on the side of the island cabinet, just under the work surface, ie. Not more than 300 mm below the counter work surface. This will allow standard kitchen appliance cords to reach the receptacle.

You may be able to install a receptacle in a partial wall or raised backsplash where they are available above the counter. Check with your local electrical inspector.


Island Counter – Receptacle Required

1. Greater than 300 mm and

2. Greater than 600 mm between edge of counter and sink

11

2


Where islands have a cantilever extension no more than 150 mm, a receptacle is permitted on the underside within 300 mm of the top of the counter

Receptacles must be within 300 mm of the top of the counter to facilitate easy reach of appliance cords that are 900 mm long

Receptacle


Receptacle is not required in an island counter where there is less than 300 mm on both sides and in front of the stove or sink

Note: a movable island does not require a receptacle. It would not have a stove or sink


Where there is 300 mm or greater counter space on each side and in front of the sink, then it is considered one work surface and only one receptacle is required


Where there is 300 mm or greater counter space on each side but not in front of the sink or stove, then it is considered two separate work surfaces and two receptacles are required. This is required so an appliance cord is not laid across the sink.


Receptacles in Kitchens

Similar to the rules for a island counter, a kitchen peninsula also requires its own receptacle.

A peninsula is a counter that is attached to the counter work surface that is attached to a wall.

An additional receptacle is required for a peninsula counter space that is at least 600 mm for the long dimension and 300 mm for the short dimension.


Receptacle

Kitchen Peninsular

Where the peninsular is greater than 600 mm in length and 300 mm or greater in width, one receptacle is required

Receptacle could have been placed here

Length

Width


Sink Location

Mini quiz:

If the counter on each side of the sink is greater than 300 mm in width, how many receptacles are required and where?


Minimum Height of Luminaires Any luminaire that is located less

than 2.1 m above the floor and is readily accessible must be protected by a guard or location.

However, a short drop light with a flexible connection may be used in lieu of a rigid luminaire.


The rigid connection for the luminaires on the right side over the island are permitted to be a rigid connection.

The flexible connection for the luminaire over the movable table is required since the table is not permanent in nature and if moved the flexible connection will permit the luminaire to move if struck.

Ontario Electrical Safety Code – TR Receptacles

Tamper-Resistant Receptacles

All receptacles of CSA Configuration 5-15R and 5-20R must be tamper-resistant and marked as such. However, receptacles for the following appliances are not required to be tamper-resistant;

If the receptacle is inaccessible by locating it behind the appliance or

2 m above floor or finished grade What is a tamper-resistant receptacle?

Ontario Electrical Safety Code – GFCI’s

The Ground Fault Circuit Interrupter (GFCI) Zone

A GFCI protects people by interrupted or turning off the circuit if leakage of current exceeds a range of 4 to 6 mA of current. It does this within 25 ms.

Leakage of current usually involves the body of a person who is grounded and accidentally touches the energized part of the circuit. Using electrical appliances around water can be fatal if the appliance is dropped into a sink full of water or into the running water.

Therefore, all 15 amp and 20 amp receptacles within 1.5 m of sinks, wash basins, bathtubs or shower stalls must be protected by a GFCI of the Class A type. Alternative to providing a GFCI receptacle, a GFCI circuit breaker may be provided.

Ontario Electrical Safety Code – GFCI’s

Note 1; all 15 amp and 20 amp receptacles within 1.5 m of sinks, wash basins, bathtubs or shower stalls must be protected by a GFCI of the Class A type.

Alternative to providing a GFCI receptacle, a GFCI circuit breaker may be provided.

Ontario Electrical Safety Code - GTK

Good to Know The wall switch that controls the luminaire is not

required to be located in the same room as the luminaire. However, in the case of a bathroom, a switch

cannot be located within 1 metre of a bathtub or shower.

The switch may be located not less than 0.5 metre if protected by a GFCI Class A.

If the above is not possible, the designer may have to locate the switch outside the bathroom or change the bathroom layout
