A-11.2.1.2. Existing Building Upgrade Mechanism ModelBackground and Intent. When work is carried out to an existing building, the By-law requires that the building
be upgraded to an "acceptable" level. On April 20, 2004 Council approved a new model
for determining the "acceptable" level of Building By-law upgrade for existing buildings
undergoing alterations under the City’s building permit process.
Prior to April 20, 2004, the upgrade mechanism model was based primarily on construction
values. The new upgrade trigger mechanism model determines the required "acceptable"
level of upgrade for an existing building using the concept of "Project Types and
Categories of Work".
The intent of the upgrade triggers is to provide a road map for building owners and
designers to determine the required level of Building By-law upgrade for an existing
building as a function of the project types and the related categories of work.
The upgrade mechanism model is not intended for existing one-and two-family dwelling
buildings. Except as required in Section 11.4. for the conversion of existing buildings,
the upgrade requirement for these types of buildings is defined in Article 11.2.1.4.
Voluntary Building By-Law Upgrades. Where a voluntary upgrade for fire alarm systems, sprinkler systems, exits, accessibility,
seismic work, building envelope repair, washrooms and kitchens for single room accommodation
or energy efficiency is performed, it is not the intent of this By-law to require
the owner to further upgrade the building provided no other work is included in the
project. If other work is included in the project, the upgrade requirement will only
be based on the non-voluntary work proposed.
Project Types and Related Categories of Work
The upgrade mechanism model is based on the following defined three Project Types
and related Categories of Work as illustrated in Table A-11.2.1.2.A
| Table A-11.2.1.2.A Project Types and Related Categories of Work |

REHABILITATION PROJECT TYPE (Flow Chart No. 1)
Voluntary Building By-law Upgrades — Voluntary Building By-law upgrades are limited to alterations for fire alarm, sprinkler,
exit, accessibility, seismic, building envelope, washrooms and kitchens for single
room accommodation and energy efficiency work to an existing building.
Repair — Repair pertains to a limited scope of interior or exterior renovation work to replace
existing building components with functionally equivalent components. Repair work
may not include work that increases the usable floor area of a building, creates an
interconnected floor space, supports an addition or change of use, or the consolidation
of more than one existing suite into a single tenant space. If the rehabilitation
includes other categories of work or project types such as a change of major occupancy
classification or an addition, then the most restrictive upgrade levels from all project
types would be applied. For Repairs, an E1 level of energy upgrade shall be applied.
Small Suite — The upgrade trigger Small Suite pertains to limited renovation work within a small
suite as defined in Division A, Article 1.4.1.2. Small Suite work may include reconfiguration
of the interior space of the suite, but may not include work on more than level (storey
or mezzanine), interconnected floor spaces, exterior renovations, or the consolidation
of more than one existing suite into a single new tenant space. If the renovation
includes other categories of work or project types such as a change of major occupancy
classification or an addition, then the most restrictive upgrade levels from all project
types would be applied. For Small suite renovations, an E2 level of energy upgrade
shall be applied.
Minor Renovation — Minor renovations mean work within a single tenant space which may occupy multiple
levels in a building. Minor renovations may include reconfiguration of the interior
space of the suite as well as exterior renovations or the consolidation of more than
one existing suite into a single new tenant space; however, a change of major occupancy
classification is not considered to be a minor renovation type project. Where the
renovation includes a new interconnected floor space or a new mezzanine, this work
would not be considered to be a minor renovation. New mezzanines are considered to
be additions. If the renovation includes other categories of work or project types
such as a change of major occupancy classification or an addition (mezzanine), then
the most restrictive upgrade levels from all project types would be applied.
Major Renovation — Major renovations means work which may include (singly or in combination): Interior
re-configuration of multiple tenant spaces, interconnected floor spaces, exterior
alterations, or alterations that create more than one new tenant space. However, where
such renovation includes a change of major occupancy classification or a new mezzanine,
this work would not be considered as a major renovation. New mezzanines are considered
to be additions. If the renovation includes other categories of work or project types
such as a change of major occupancy classification or an addition (mezzanine) then
the most restrictive upgrade levels from all project types would be applied.
Reconstruction — Reconstruction means any project where: extensive renovations are being carried on
throughout the entire building and the building is completely gutted; where all drywall
and plaster has been removed from the interior walls; all drywall, plaster, insulation
and exterior cladding has been removed from the exterior walls ; and all floor and
roof membranes and coverings have been removed. Reconstruction also includes substantial
reconfiguration of the interior floor space. Reconstruction means exposing the primary
structure of the building on all interior and exterior walls, floors and roof with
only the primary structural elements remaining in place (the building skeleton). Where
work which might otherwise be considered as reconstruction, is undertaken solely to
facilitate the repair of a building due to envelope damage, insect infestation, mould
abatement or asbestos abatement, then the work
would not be considered a reconstruction: it would be considered a repair, minor renovation
or a major renovation as defined in this By-law.

Notes to Figure A-11.2.1.2.-A1:
CHANGE OF MAJOR OCCUPANCY CLASSIFICATION PROJECTS (Flow Chart No. 2)
Change of Major Occupancy Classification — Change of major occupancy classification means a change of use within a building,
a suite, or its constituent floor areas where the proposed use is outside of the defined
uses of the existing major occupancy classification permitted for the building, the
suite, or its constituent floor areas.
Small Suite Change of Major Occupancy Classification — Small suite change of major occupancy classification means a change of use within
a small suite, or its constituent floor areas where the occupant load for the entire
suite does not exceed 60 persons and the small suite is limited to a Group A, Division
2, Group D, Group E, Group F, Division 2 (wholesale showroom), or Group F, Division
3 major occupancy.

Notes to Figure A-11.2.1.2.-A2:
ADDITION PROJECTS (Flow Chart No. 3)
Horizontal Addition — Horizontal additions include both “minor” and “major” horizontal additions. A minor
horizontal addition is any expansion of a floor area beyond the extents of the existing
floor area in which it is located by not more than 25 per cent of the existing building
area, or by not more than 500 m2 in aggregate floor area. A major horizontal addition is any expansion of a floor
area beyond the extents of the existing floor area that exceeds the limits permitted
by a minor horizontal addition. Any construction creates new floor area that in-fills
existing roof or deck areas, or is superimposed over existing building structure or
floor area is not considered a horizontal addition.
Vertical Addition — Vertical additions include both “minor” and “major” vertical additions. A minor vertical
addition is the addition of new floor area (storey or mezzanine) that in-fills existing
roof or deck areas, or is superimposed over existing building structure or floor area,
with an aggregate floor area increase of not more than 25 per cent of the building
area, or by not more than 500 m2 in aggregate floor area. A major vertical addition is an addition that increases
the aggregate floor areas or mezzanine area increase that exceeds the limits permitted
by a minor vertical addition.

PROCEDURE FOR USING THE UPGRADE MECHANISM MODEL
The following steps outline a recommended procedure for using the upgrade trigger
mechanism model.
Step 1 — Determine the appropriate Project Type(s) and Related Category or Categories of Work
as a function of the scope of work for the alteration.
Step 2 — Determine the Required Design Upgrade Level Based on the Category of Work for the
Project
The required upgrade levels for fire, life & health safety; structural safety; non-structural
safety; accessibility for persons with disabilities; and energy efficiency are to
be determined using each of the applicable project type flow charts and the related
category of work
For Rehabilitation Type Projects use Flow Chart No. 1.
For Change of Major Occupancy Type Projects use Flow Chart No. 2.
For Addition Type Projects use Flow Chart No. 3.
For Change of Major Occupancy Type Projects use Flow Chart No. 2.
For Addition Type Projects use Flow Chart No. 3.
NOTE: Where a project involves more than one category of work, the most restrictive
upgrade level, as determined from each category of work, shall determine the upgrade
design level.
Step 3 — Determine the objective and acceptable solution for the most restrictive upgrade
level for fire, life and health safety; structural safety; non-structural safety;
accessibility for persons with disabilities; and energy efficiency. The most restrictive
upgrade levels are the design upgrade levels that are to be applied to the existing
building.
The model is based on incremental upgrade levels for each of the fire, life and health
safety (F), structural safety (S); non-structural safety (N); accessibility (A); and
energy (E) objectives. For each of the upgrade levels, the model states the objective
of the upgrade level as well as the corresponding acceptable solution that is deemed
to meet the intended objective of the applicable upgrade level. The objective statement
and acceptable solution for each F, S, N and A upgrade level is defined in Table A-11.2.1.2.B. The objective statement and acceptable solution for each E upgrade level is defined in Tables A-11.2.1.2.C and A-11.2.1.2.D.
The alternative acceptable solution for energy efficiency requires that the determined
E design upgrade level is used to enter Table A-11.2.1.2.C to obtain a solution. The solution column in Table A-11.2.1.2.C provides the L level to enter Table A-11.2.1.2.D. Within the L Level row of Table A-11.2.1.2.D the user is provided with various Section rows under the Section column. Each Section row provides one or more alternative acceptable solutions under the Alternative Acceptable
Solution Options column. Each alternative acceptable solution is identified as a separate
numeric solution. There are one or more alternative acceptable solutions for each
Section row. The “Select 1-L*”
solution in Table A-11.2.1.2.C means that only one (1) of the alternative solutions in the Alternative Acceptable Solution Options column in Table A-11.2.1.2.D are required to meet the objective. It is up to the user to determine which Section(s) in the Section column and corresponding alternative acceptable solution in the Alternative
Acceptable Solution Options column is (are) used to satisfy the objective. Within
any 5 year period, when an alternative acceptable solution has been used previously
within the project area, then that option is not permitted to be used as an alternative
acceptable solution.
Step 4 — Determine Any Other Requirements that may be Applicable. Other Building By-law requirements
may be applicable to the existing building project. Review the Overall Conditions
for the Upgrade Trigger Model to determine if other requirements are applicable.

HAZARD INDEX TABLE
The hazard indices for various building uses are indicated in Table A-11.2.1.2.E.
The required level of Building By-law upgrade for a Change of Major Occupancy Type
projects is dependent on whether or not the Hazard Index has increased for the proposed
alteration. Hazard Index ratings are intended to reflect the level of fire and life
safety risk to occupants for various building uses. Hazard index ratings range from
1 to 6, with a hazard index of rating of 6 representing the highest risk to occupants.

A-11.2.1.3 Sprinkler Installation Determination Where Dwelling Units Are Added
Table 11.2.1.2. provides a matrix that determines sprinkler upgrades for existing
unsprinklered or partially sprinklered buildings. The location of the newly created
dwelling unit will determine the extent of the sprinkler coverage for the subject
building.
A-11.2.1.4.(1)(d) Replacement ValueThe term “replacement value” is used in several places in Part 11, as a baseline for
determining of the applicability of specific upgrade requirements. The term refers
to an assessed cost to replace the structure in its current state, the net asset value.
This is similar to what would be considered the “book value” in financial terms, in
that it considers the depreciated cost of the asset. This is not intended to be an
assessment of the construction, planning, and ancillary costs that could be incurred
if the structure in question was built as new construction.
