Definitions for Categories of Work
(Where a project comprises more than one category of work, the category of work having the most restrictive upgrade level shall apply.)
Rehabilitation Projects [ See Flow Chart No. 1 ]
Voluntary Building By-law Upgrades – Voluntary Building By-law upgrades are limited to fire alarm, sprinkler, exit, accessibility, seismic and building envelope upgrades to an existing building.

Minor renovations may include reconfiguration of the interior space as well as exterior renovations, however change of use or major occupancy classification is not permitted for a minor renovation type project. Where the renovation includes a new interconnected floor space or a new mezzanine, it shall not be considered as a minor renovation. (New mezzanines are considered to be vertical additions.)
Major Renovation – Major renovations are limited to work within multiple tenant spaces. Major renovations may include re-configuration of the interior space, interconnected floor spaces, and exterior alterations, however change of use, change of major occupancy classification or new mezzanines may not be considered as a major renovation.
