4." Each townhouse must be structurally independent and
capable of being removed without atfecting the adjacent dwelling unit. This provision is applicable only to
townhouses, not two-family dwellings. This independence is useful not only in the event of a fire in one unit,
but also during any remodeling or alteration. The
objective of this structural independence is that a complete burnout could occur on one side of the wall without causing the collapse of the adjacent townhouse.
This condition occurs rarely. The provision also helps if
there is ever a fire or other problem by creating a clear
separation between the units. With separate ownership and each owner having a different insurance company, the ability to gain access or get repairs made can
be difficult and time consuming. By having clearly separated units, it is much easier to determine who is
responsible and to make any needed repairs.
Each bedroom, hallway, one in the basement, and one in the attic.

Studs are offset (meaning; 1 stud flush with one side of the larger wall sill/top plates and the next stud is flush with the other side of the larger sill/top plates). Electrical boxes are staggered on the offset studs and are fire rated, steel, protected or separated by insulation. Insulation passes between the offset studs and sheetrock. 5/8” sheetrock is placed on both sides of the wall.
