What Is a 3½, 4½ or 5½ Apartment in Quebec?

A 3½ does not have 3 bedrooms: it has one. It is the most common mistake, and it costs people viewings. In Quebec, the number in a listing counts the rooms, not the bedrooms, and the « ½ » is always the bathroom.

Quick answer: a 4½ (or 4 1/2) is a 2 bedroom: kitchen, living room, two bedrooms and a bathroom. A 3½ has 1 bedroom, a 5½ has 3 (or 2 bedrooms and a closed dining room).

The shortcut: bedrooms = the number in the listing minus 2. A 4½: 4 − 2 = 2 bedrooms. A 5½: 3 bedrooms. The two rooms you take away are the kitchen and the living room. The one exception: if a room is a dining room or a double living room, there is one bedroom fewer.

Why Quebec uses « and a half »

In the rest of Canada and the US, listings describe an apartment by its bedrooms: « 1 bedroom », « 2 bedrooms ». Quebec's rental market counts every room you live in instead, and the bathroom counts as half a room, because you don't live in it the way you live in a living room or a bedroom. The expression is so particular to Quebec that it appears in the University of British Columbia's Dictionary of Canadianisms, which defines a « three-and-a-half » as a one-bedroom apartment.

That is why you see 3½, 4½ and 5½ in listings, and never a plain 4. The system is handy once you know it, but it often confuses newcomers and people moving from another province.

How to count rooms

The rule: add up the rooms you live in, then add ½ for the bathroom.

Counts as a roomDoesn't count
The kitchenHallways and the entrance
The living roomClosets and walk-ins
Each bedroomThe balcony
A closed dining roomThe laundry room

Example: kitchen + living room + 2 bedrooms = 4 rooms. Add the bathroom: it is a 4½.

1 KITCHEN 2 LIVING ROOM 3 BEDROOM 4 BEDROOM ½ BATHROOM 0 ENTRANCE AND HALL 0 STORAGE
Typical plan of a 4½: kitchen, living room, 2 bedrooms and a bathroom. The entrance, the hall and storage do not count. 1 + 2 + 3 + 4 + ½ = 4½

Good to know:

  • It is a Quebec market convention, not an official standard. Two landlords may count slightly differently.
  • A double living room (two connecting living rooms, common in Montréal plexes) counts as 2 rooms. A « 5½ » can therefore have only 2 bedrooms.
  • A second bathroom usually doesn't add to the number. It is listed separately (« 4½ with 2 bathrooms »).
  • When the kitchen and living room are open-concept, the counting varies. If in doubt, ask how many closed bedrooms there are.

* Rents of our free apartments, updated automatically from our inventory. The exact rent depends on the building, the floor and what is included.

Tip: the number of rooms says nothing about size. Two 4½ apartments can be very different sizes depending on the building's age and the layout. Always ask for the square footage before you visit: it is the best way to compare two listings of the same size.

Some rooms are staged; the furniture is not part of the apartment.

3½, 4½ or 5½: which one fits you?

A family with two children or more5½

The roommate sum: a 4½ shared by two splits one rent in half, against When available for a 3½ on your own. Each of you has a closed bedroom, and it is often the cheapest way not to live in a studio.

The 3½ (1 bedroom) is the classic size for one person or a couple: a real closed bedroom, a living room and a kitchen. It costs less to rent and to heat than a 4½. Our 1 bedroom apartments in Ahuntsic, at 1020 rue de Salaberry, include heating and hot water.

The 4½ (2 bedrooms) adds a second bedroom: a home office, a child's room or a roommate's room. It is the most sought-after size in Greater Montréal. Our 2 bedroom apartments in Boucherville (453 rue Darontal) and our 2 bedroom apartments in Laval (1700 boul. Lévesque Est, Duvernay) include heating and electricity: no Hydro-Québec bill to pay.

The 5½ (3 bedrooms) gives you one more room: either a third bedroom or a closed dining room. Before you visit, ask which one it is: for a family with two children, the difference is huge.

Mistakes to avoid when reading a listing

  1. A « bedroom » with no window or no door. In practice, a real bedroom has both. If the listing counts a closed room with no window, ask.
  2. A living room split by a partition. Some landlords divide a living room with a light wall to advertise a 4½ where most people would see a 3½. Check that what is left of the living room is still usable.
  3. The kitchen: a real room or a corner of the living room? That is what separates a 1½ from a 2½, and a 2½ from a 3½. The rent follows.
  4. No square footage. Two 4½ units can be very different sizes. Ask for the square feet.
  5. Bedroom sizes. A second bedroom can be too small for a double bed and a desk. Ask for each bedroom's dimensions, or bring a tape measure to the visit.
  6. Appliances. In Quebec, many apartments are rented without a fridge or a stove. Ask whether they are included, and whether there are washer-dryer hookups or a laundry room.
  7. « Heated » or « heated and lit »? Heated means only the heating is included. Heated and lit means the electricity is too. The difference can be worth several hundred dollars a year. Our 4½ apartments at 453 rue Darontal and 1700 boul. Lévesque Est include heating and electricity.
  8. A dining room or a double living room counted as a bedroom. Especially in 5½ units: check the number of closed bedrooms.
  9. A half-basement not mentioned. It is not a problem in itself, but it changes the light. Ask which floor the unit is on.

What to check at the viewing

  • Count the closed bedrooms: a door and a window each.
  • Open the window in each bedroom. It should open without tools.
  • Measure the bedrooms if you already have your furniture, especially the second one.
  • Look at the storage: closets, walk-ins, basement storage or a locker.
  • Ask what the rent includes: heating, hot water, electricity. At CGK, each building page lists it.
  • Ask for the square footage and which floor the apartment is on.

FAQ

How many bedrooms in a 4½?

Usually two. With an open-concept kitchen and living room, confirm the number of closed bedrooms with the landlord.

Are 4 1/2, 4.5 and 4½ the same thing?

Yes. They are three ways of writing the same size: four rooms and a bathroom, so two bedrooms. Listings also say « four and a half ».

What does the ½ mean in 4½?

It's the bathroom. A 4½ has 4 rooms (kitchen, living room, 2 bedrooms) plus a bathroom.

What is a 1½?

A studio: a single room where you live and sleep, plus a bathroom. The kitchen is usually in the same room.

What is the difference between a 4½ and a 5½?

One more room. In a 5½, that room is either a third bedroom or a closed dining room. Ask which before you visit.

What is a 3½ in English?

A 1 bedroom apartment. A 4½ is a 2 bedroom and a 5½ is a 3 bedroom.

What is a 4½ in France?

A T3. In France, neither the kitchen nor the bathroom is counted: a 3½ is a T2 and a 5½ is a T4.

Is a 4½ big enough for two roommates?

Yes, it is the most common size for roommates: each has a closed bedroom, and you share the kitchen, the living room and the bathroom. Check that the two bedrooms are a similar size.

Is a 4½ always bigger than a 3½?

No. It has one more bedroom, not necessarily more square feet. A large 3½ can be roomier than a small 4½.

What is the difference between a 1½ and a 2½?

In a 2½, the kitchen is in its own room. In a 1½, everything is in the same room.

Why does the bathroom count as ½?

By convention: you don't live in it the way you live in a living room or a bedroom. No law requires it; the habit simply took hold. A second bathroom doesn't change the number either.

How much is a 4½ in Greater Montréal?

It depends on the city and what is included. According to CMHC, the average rent for a two-bedroom in the Montréal area was $1,346 in 2025, but apartments coming back on the market usually cost more.
