step up from a studio, a junior 1 might be a large studio or a loft of sorts, sometimes featuring a separate sleeping area and/or an eat-in kitchen

JUNIOR 4: a one-bedroom apartment with a separate dining room or small room. It's called a junior 4 because it features four rooms: a bedroom, a kitchen, a living room, and an extra small room.

THREE-ROOM: the best example of this is a railroad apartment (several rooms

connected by doors but no hallway), where the apartment features three rooms, but the layout doesn't lend itself to creating more than one or two bedrooms.

TWO-BEDROOM: also known as a real two-bedroom, this has two actual bedrooms, a common living space, and a kitchen which might be separate.

WING TWO-BEDROOM: this style of apartment has two bedrooms joined by a small common space, such as a kitchen, but not much more insofar as living space is concerned.

CLASSIC SIX: a three-bedroom apartment typically found in pre-war buildings. It features a large dining room, a living room, and a full, separate kitchen. Many of these beauties have been remodeled to create more apartments from the typically large space.

DUPLEX OR TRIPLEX: apartments with two or three levels, respectively. The levels may be unique in that the second or third level is for sleeping only, or they may feature actual floors with bathrooms on each level.

GARDEN APARTMENT: this is an apartment with access to a garden. If you have one of these, you'll have lots of visitors in the summer. The term can also mean a basement level apartment. Because the apartment is partially below ground, windows will be higher up on the walls. Before visiting the apartment, verify what is meant by garden apartment.

The term garden apartment is variously defined, following regional practices.

In some locales, a garden apartment complex consists of low-rise apartment buildings built with landscaped grounds surrounding them. The apartment buildings are often arranged around courtyards that are open at one end. Such a garden apartment shares some characteristics of a townhouse: each apartment has its own building entrance, or shares that entrance via a staircase and lobby that adjoins other units immediately above and/or below it. Unlike a townhouse, each apartment occupies only one level.

Such garden apartment buildings are almost never more than three stories high, since they typically don't have elevators/lifts. However, the first "garden apartment" buildings in New York, USA, built in the early 1900s, were constructed five stories high. Some garden apartment buildings place a one-car garage under each apartment. The interior grounds are often landscaped.

In other locales, a "garden apartment" is a unit built at or below grade or at ground level.

[4] The implication is that there is a view or direct access to a garden from the apartment, but this is not necessarily the case.

In most west coast cities in United States, due to the need for resisting earthquakes at a low building cost, these low rise apartments are mostly built of wooden frames with thin plaster-board based exterior and interior dry walls, despite that they can be up to 3 to 4 levels.

SECONDARY SUITE: When part of a house is converted for the ostensible use of a landlord's family member, the unit may be known as an in-law apartment or granny flat, though these (sometimes illegally) created units are often occupied by ordinary renters rather than family members. In Canada these suites are commonly located in the

basements of houses and are therefore normally called basement suites or "mother-in-law suites."

MAISONETTE: Maisonette (from the French maisonnette, meaning "little house") typically refers to larger apartments spreading across two or more floors of an apartment building connected by staircases within the maisonette.

In the UK, the term "maisonette" may be used to distinguish dwellings, which have their own entrance independent from the rest of a multi-storey block, and are located above a shop or other retail establishment. This is different to flats which are usually reached through shared entrance doors, stairs or corridors. This definition of maisonette includes smaller maisonettes occupying a single floor of a block, including designs also known as Cottage flats and Tyneside flats

TWO-STOREY FLAT: In Milwaukee vernacular architecture, a Polish flat is an existing small house or cottage that has been lifted up to accommodate the creation of a new basement floor housing a separate apartment, then set down again; thus becoming a modest two-storey flat.

COMMUNAL APARTMENT: In Russia, a communal apartment is a room with a shared kitchen and bath. A typical arrangement is a cluster of five or so room-apartments with a common kitchen and bathroom and separate front doors, occupying a floor in a pre-Revolutionary mansion. Traditionally a room is owned by the government and assigned to a family on a semi-permanent basis.

FACILITIES: Apartments may be available for rent furnished with furniture or

unfurnished into which a tenant moves in with their own furniture. Serviced apartments, intended to be convenient for shorter stays, include soft furnishings and kitchen utensils, and maid service.

Laundry facilities may be found in a common area accessible to all the tenants in the building, or each apartment may have its own facilities. Depending on when the building was built and the design of the building, utilities such as water, heating, and electricity may be common for all the apartments in the building or separate for each apartment and billed separately to each tenant (however, many areas in the US have ruled it illegal to split a water bill among all the tenants, especially if a pool is on the premises). Outlets for connection to telephones are typically included in apartments. Telephone service is optional and is practically always billed separately from the rent payments. Cable television and similar amenities are extra also. Parking space(s), air conditioner, and

extra storage space may or may not be included with an apartment. Rental leases often limit the maximum number of people who can reside in each apartment. On or around the ground floor of the apartment building, a series of mailboxes are typically kept in a location accessible to the public and, thus, to the mail carrier too. Every unit typically gets its own mailbox with individual keys to it. Some very large apartment buildings with a full-time staff may take mail from the mailman and provide mail-sorting service. Near the mailboxes or some other location accessible by outsiders, there may be a buzzer (equivalent to a doorbell) for each individual unit. In smaller apartment buildings such as two- or three-flats, or even four-flats, rubbish is often disposed of in trash containers similar to those used at houses. In larger buildings, rubbish is often collected in a common trash bin or dumpster. For cleanliness or minimizing noise, many lessors will place restrictions on tenants regarding keeping pets in an apartment.
