What does walkup mean?
A walkup is most commonly an apartment or building that can be entered directly from the street, without a lobby or elevator. The word is especially associated with American housing and appears frequently in real-estate listings, where it may indicate either a walk-up apartment or a larger building containing such apartments. In business and service settings, a walkup can also be a customer or visitor who arrives without an appointment, though “walk-in” is often more natural for that person. The same word functions as an adjective before nouns such as “apartment,” “building,” “customer,” and “visit.” Although commonly written with a hyphen as “walk-up,” the closed form “walkup” is also established. The term is practical and immediately descriptive: it identifies buildings without elevator access and distinguishes unscheduled customers from people arriving by appointment.
An apartment or building entered directly from the street without a lobby or elevator; also, a customer or visitor who arrives without an appointment.
"The walk-up required us to carry every box up three flights of stairs."
The customer sense is chiefly associated with retail and service settings, where “walk-in” may be used instead.
Having direct access from the street without a lobby or elevator, or handled without an appointment.
"The dentist said she could fit me in as a walk-up patient at two o'clock."
This form is common in real-estate terminology and in descriptions of appointment-free service.
The plural refers to multiple street-access apartments or buildings, or to multiple customers or visitors who arrive without appointments.
"The building contains several walk-ups on its upper floors."
No elevator? A walk-up apartment makes your daily commute a stair-climbing workout.

Etymology of walkup
The word was formed in North American English by combining “walk” with “up,” with “up” conveying direct or immediate access from the street. “Walk” descends from Old English “wealcan,” while “up” comes from Old English “up.” The compound initially developed around buildings entered directly from the sidewalk, and the unscheduled-customer sense developed later in business and service contexts.
How walkup is actually used
The term is especially common in American housing and business usage. It is often written as the hyphenated “walk-up,” although “walkup” is also used, particularly in property listings. In the appointment sense, it is less common than “walk-in” and may sound mildly informal or service-oriented.
Easily confused with walkup
A walk-in is someone who arrives without an appointment, whereas a walkup can mean a street-level apartment without a lobby or elevator as well as an unscheduled customer or visitor.
