Change of use permits
When a building or unit changes what it is used for, the building code and zoning can change too. We review the new use and prepare the drawings for the permit.
Where most of our change of use clients start
The sheets in a typical permit set
Every property is different, so we confirm the exact list with your city. Most applications include:
EXAMPLE SHEETS · ILLUSTRATIVE
Included when you work with KS
- Building code analysis of the old and new use
- Zoning check for the new use
- Exit capacity and travel distance review
- Fire separations from neighbouring units
- Washroom and accessibility requirements
- Floor plans and code matrix
- Application, submission and comment responses
We coordinate
- Structural review if floor loads increase
- Mechanical engineer for ventilation changes
- Sprinkler designers
We tell you up front if any of these apply, so there are no surprise add-ons later.
Key requirements we design for
Zoning
Whether the new use is permitted in that location.
Occupancy
How the building code classifies old and new uses.
Exits
Exit capacity for the new occupant load.
Fire separations
Separations from neighbouring units.
Washrooms
Fixture counts for the new use.
Structure
Floor loads if the new use is heavier.
Before we design: what we check when the use changes
The Building Code groups buildings by how they are used. When a space moves into a different group, or the new use is more demanding, the building may need upgrades even if very little construction is planned.
We compare the old use with the new one, then check exits, washrooms, fire separations and accessibility against the new requirements. Some spaces need very little; others need a second exit or new washrooms.
We also check zoning, because the new use has to be permitted at that address, and floor loads, because some uses are heavier than others.
Why these applications get sent back
These are comments plan examiners often raise. We address each one in the drawings before we submit.
From site visit to issued permit
"We had such a wonderful experience working with the team of KS Group, on our home interiors. They really took the time to understand our vision and brought it to life with so much creativity, care, and attention to detail."
Common questions
What counts as a change of use?
When the new use falls into a different occupancy or increases the hazard or load, for example retail to restaurant.
Do I need a permit if I am not building anything?
Possibly. A change of use can need a permit even without construction.
Can you check before I sign a lease?
Yes, and it is the best time to do it.
What if zoning does not allow my use?
A minor variance or rezoning may be options. We will tell you.
What should I send for a quote?
The address, previous use, your new use and any drawings.
