Rooms and spaces, glass, windows and doors: BCIN House

Values this chapter turns on

master bedroom, or 8.8 m² with built-ins: 9.8 m²; master bedroom, or 8.8 m² with built-ins
min doorway width, bathroom: 610 mm; min doorway width, bathroom
min hallway width in a dwelling unit: 860 mm; min hallway width in a dwelling unit
min glass area, living and dining rooms: 10%; min glass area, living and dining rooms

Sections 9.5, 9.6 and 9.7 control the size of rooms and openings in a house: ceiling heights, minimum room areas, hallway and door widths, glass sizes, window glass areas, and how windows and doors resist weather and forced entry. Most questions are lookups with a number, or small calculations such as "what glass area does this bedroom need?".

Ceiling heights and room areas

Section 9.5 applies to dwelling units used year-round as a principal residence (OBC Div. B 9.5.1.0A.). Areas and heights are measured between finished surfaces (OBC Div. B 9.5.1.1.), and minimum floor areas exclude closets and built-in bedroom cabinets unless stated (OBC Div. B 9.5.1.1A.).

Combination rooms. Two areas count as one room when the opening between them is the larger of 3 m² or 40% of the wall on the dependent side. The opening cannot contain doors or windows, and a bedroom needs direct passage (OBC Div. B 9.5.1.2.).

Ceiling heights follow Table 9.5.3.1. (OBC Div. B 9.5.3.1.). In our words:

Space	Minimum
Living, dining, kitchen	2,300 mm over 75% of required area, 2,100 mm clear at any point
Bedroom	2,300 mm over 50% of required area, or 2,100 mm over all of it; floor under 1,400 mm clear does not count
Basement space	2,100 mm over 75% of the basement; 1,950 mm under beams and ducts
Bathroom, laundry above grade	2,100 mm where a person would stand
Halls, vestibules, other finished rooms	2,100 mm
Secondary suite	1.95 m ceiling, 1.85 m under beams and ducts

A storage garage needs 2 m clear height (OBC Div. B 9.5.3.3.).

Room areas come from Subsections 9.5.3A. to 9.5.3E.:

Room	Minimum area
Living area	13.5 m² (11 m² when combined with kitchen and dining in a unit for not more than two people)
Dining space combined with other space	3.25 m²
Separate dining room	7 m²
Kitchen	4.2 m² (3.7 m² for a unit for not more than two people)
Master bedroom (one per unit)	9.8 m², or 8.8 m² with built-in cabinets
Other bedrooms	7 m², or 6 m² with built-in cabinets
Bedroom space in combination	4.2 m²
Bachelor unit, all spaces combined (not more than two people)	13.5 m²

Smaller areas are allowed when it can be shown they suit the intended use, for example with built-in furniture (OBC Div. B 9.5.1.3.). Every dwelling unit needs an enclosed space big enough for a water closet, lavatory and tub or shower, and a door on every room with a water closet (OBC Div. B 9.5.3F.2.).

Hallways and doorway sizes

Hallways inside a dwelling unit are at least 860 mm wide. They may drop to 710 mm where only bedrooms and bathrooms are at the far end and a second exit is provided near that end or in each bedroom (OBC Div. B 9.5.4.1.).

Door openings follow Table 9.5.5.1. (OBC Div. B 9.5.5.1.). All heights are 1,980 mm.

Doorway	Min. width
Required entrance to the unit, vestibule, stairs to a finished level, the line of passage to the basement, utility rooms	810 mm
Walk-in closet, bathroom, water-closet room, shower room, rooms off a 710 mm hallway	610 mm
Other rooms, exterior balconies	760 mm

Inside a secondary suite, doors may be 1,890 mm high where the 1.95 m ceiling rule is used.

Glass

Section 9.6 covers glass in interior doors and windows, closets, site-built exterior windows, doors and skylights, shower and tub enclosures, and glazed panels (OBC Div. B 9.6.1.1.). Mirrored doors may only be used on clothes closets (OBC Div. B 9.6.1.2.).

Window pane sizes come from Tables 9.6.1.3.-A to -F (based on the SB-1 hourly wind pressure) and door glass from Table 9.6.1.3.-G (OBC Div. B 9.6.1.3.). To read Table -G, pick the glass thickness row and the glass type column. For example, 4 mm fully tempered door glass may be up to 4.00 m², while 4 mm annealed is limited to 1.00 m² (Table 9.6.1.3.-G).

Safety glazing (tempered or laminated, or wired glass) is required for sidelights over 500 mm wide that could be mistaken for doors, storm door glass and sliding door glass at dwelling unit entrances (OBC Div. B 9.6.1.4.(1)). Other entrance door glass needs it when the pane exceeds 0.5 m² and extends to within 900 mm of the bottom of the door. Shower and tub enclosure glazing must be Class A safety glazing.

Windows, doors and skylights

Section 9.7 covers windows, doors and skylights between conditioned space and unconditioned space or the outdoors, plus main entrance doors (OBC Div. B 9.7.1.1.). Each dwelling unit entrance needs a door, and the main entrance door needs a door viewer, glazing, or a sidelight (OBC Div. B 9.7.2.1.).

Minimum glass areas follow Table 9.7.2.3. (OBC Div. B 9.7.2.3.). Door and skylight glass counts as window glass, and in a combination room the stricter requirement governs.

Room	No electric lighting	With electric lighting
Living and dining rooms	10% of area served	10%
Bedrooms and other finished rooms	5%	5%
Kitchen	10%	not required
Laundry, basement rec room, unfinished basement	4%	not required
Water-closet room	0.37 m²	not required

Performance. Windows, doors and skylights must resist precipitation, wind loads, air leakage, insects and vermin, forced entry where required, and be easily operable (OBC Div. B 9.7.3.1.). Metal frames need a thermal break, with exceptions for vehicle doors, storm units and fire-rated units (OBC Div. B 9.7.3.3.). Where the January design temperature is between -15°C and -30°C, windows and doors have a maximum U-value of 2.0 W/m²K (skylights 3.0); colder than -30°C, 1.7 (skylights 2.7) (Table 9.7.3.3.). Manufactured units meet the NAFS standard and the Canadian Supplement, with a minimum Performance Class R (OBC Div. B 9.7.4.3.).

Forced entry. For swinging entrance doors to dwelling units and doors to attached garages (OBC Div. B 9.7.5.2.):

Item	Requirement
Wood door	solid core or stile-and-rail, at least 45 mm thick
Deadbolt	cylinder with at least 5 pins, bolt throw at least 25 mm
Inactive leaf	top and bottom bolts with at least 15 mm engagement
Hinge screws in wood frames	at least 2 per hinge into solid wood at least 30 mm
Blocking	solid, both sides at lock height

A door that meets ASTM F476 Grade 10 is exempt from the detailed list. Windows within 2 m of adjacent ground must meet the forced entry clause of the NAFS standard (OBC Div. B 9.7.5.3.). Installation follows CSA A440.4, and windows and doors are sealed to the air barrier (OBC Div. B 9.7.6.1.).

Common traps

Using the 9.8 m² master bedroom figure for every bedroom.
Forgetting that the kitchen glass requirement disappears with electric lighting but the living room one does not.
Reading 810 mm for a bathroom door. Bathrooms are 610 mm.
Measuring ceiling heights to the joists instead of the finished ceiling.
