Link homes are similar to semi-detached homes as they both share a
wall with a neighbouring house. The main difference is that link homes
do not share a living space wall. They are typically attached at a
garage or via the basement, offering more privacy than a semi-detached
home. Link homes are perfect for those who are looking for the
benefits of a detached home and the affordability of a semi-detached
home. If privacy, affordability, and space is important to you,
consider a link home! - See more at:

Linked houses are "row-houses" or a "semi-detached houses" that are
linked structurally only in their foundations. Above ground, these
houses appear to be detached houses. Linking up their foundations cuts
the cost of constructing them.

In the building code, there are basically 2 kids of residential
1&2 family and Multifamily
The rules really start racking up in multifamily
"Single family" is a totally detached home.
The 2 family is typically called semi detached or duplex.
That is 2 homes that share a wall and a zero lot line.

Multi family can be row houses, multiple zero lot line residences that
you own from basement to roof.
There are also multi story "condo/co op" type buildings with one
dwelling over another. The real estate brokers can play all sorts of
games with what they call them but that is the basic classification
breakdown.
