categories of repair, renovation, alteration and reconstruc-
tion. Specific requirements are established for each category
of work in these provisions.
AJ101.3 Multiple categories of work. Work of more than
one category may be part of a single work project. All related
work permitted within a 12 -month period shall be considered
a single work project. Where a project includes one category
of work in one building area and another category of work in
a separate and unrelated area of the building, each project
area shall comply with the requirements of the respective cat-
egory of work. Where a project with more than one category
of work is performed in the same area or in related areas of
the building, the project shall comply with the requirements
of the more stringent category of work.
SECTION AJ102
COMPLIANCE
AJ102.1 General. Regardless of the category of work being
performed, the work shall not cause the structure to become
unsafe or adversely affect the performance of the building;
shall not cause an existing mechanical or plumbing system to
become unsafe, hazardous, insanitary or overloaded; and
unless expressly permitted by these provisions, shall not
make the building any less compliant with this code or to any
previously approved alternative arrangements than it was
before the work was undertaken.
AJ102.2 Requirements by category of work. Repairs shall
conform to the requirements of Section AJ301. Renovations
shall conform to the requirements of Section AJ401. Altera-
tions shall conform to the requirements of Section AJ5o1 and

deemed to be equivalent and its use authorized by the build-
ing official.
AJ102.7 Other alternatives. Where compliacec with these
provisions or with this code as required by these provisions is
technically infeasible or would impose disproportionate costs
because of structural, construction or dimensional difficul-
ties, other alternatives may be accepted by the building offi-
cial. These alternatives may include materials, design
features and/or operational features.
AJ102.8 More restr(ctive requirements. Buildings or sys-
tems in compliance with the requirements of this code for
new construction shall not be required to comply with any
more restrictive requirement of these provisions.

these provisions from being modified as long as they remain
in compliance with the applicable requirements for new con-
struction.
