A tenant fit-out starts with the unit you inherited, not a standard drawing package. The existing space, landlord/base-building criteria and proposed construction determine what the Toronto permit set actually needs to show.
iPermit handles general commercial fit-outs and renovations that do not belong to a more specialized business-use service.
In Toronto, a commercial tenant fit-out commonly needs a building permit when the work changes partitions or doors, washrooms or plumbing, ceilings or affected building systems, fire/life-safety conditions, or the approved use of the unit. A finish-only refresh may have a different permit scope.
This page is the catch-all for general tenant improvements, leasehold improvements and commercial renovations. If the business type or approved use is the real decision, route the project before the generic fit-out scope grows around the wrong assumptions.
Stay on this page when you are adapting a leased commercial unit and no dedicated business-use page better owns the project. Examples can include salon or personal-service space, studio/training space, warehouse-office alterations or another general commercial interior renovation.
Use a dedicated service when the operation introduces its own approval decisions: Restaurant, Retail, Office, Medical/Dental Clinic, Daycare or Auto Repair.
If the main uncertainty is whether the business use is permitted or whether the building can support a different occupancy/use, start with Zoning Review or the Change of Use Permit service before treating the fit-out layout as final.
Send project context first, the next step can then focus on scope, information gaps and the right page or service route.
The same proposed business can create a very different permit scope depending on the condition of the unit at possession.
| Starting condition | What may already exist | What still needs verification |
|---|---|---|
| Base-building shell / first-generation space | Demising walls, entrance, basic life-safety/base-building systems and service stubs may exist, but little or no tenant layout has been built. | Where services actually terminate, what the landlord is providing, washroom/ceiling/building-system assumptions, and which parts of the fit-out are tenant work. |
| Second-generation fitted unit | Partitions, ceilings, washrooms, lighting, HVAC distribution, plumbing and previous tenant improvements may already be present. | Whether the old plans match the physical unit, which systems can remain, and what has to move for the new layout or equipment. |
| Same-use takeover with limited alterations | The previous operator may have used the unit in a similar way and much of the built work may be reusable. | The approved records, actual condition and proposed changes. A similar previous business does not make new partitions, plumbing, equipment or other material alterations automatically permit-free. |
The useful first question is therefore not “What is in a standard fit-out package?” It is “What is already here, what can stay, and what are we changing?”
A lease plan shows the tenant space but may not identify key building systems, available services, or landlord construction requirements.
Before finalizing the permit scope, review landlord criteria, base-building drawings, and requirements for HVAC, plumbing, electrical, fire protection, and demising walls.
Landlord approval and Toronto Building approval are separate processes. iPermit coordinates the permit information within the agreed project scope.
Toronto reviews applicable work through its non-residential interior-alteration building-permit framework. The required drawings and supporting information depend on the construction and code issues in the real project—not on a fixed tenant-fit-out checklist.
| Fit-out layer | Existing condition to verify | When the permit scope grows |
|---|---|---|
| Partitions, doors & rooms | Current layout, exits, corridors, room uses, fire separations and door locations. | Walls/doors move, rooms are enclosed, travel paths change, or construction/fire-separation details need to be documented. |
| Washrooms & plumbing | Existing fixtures, accessible route, plumbing locations and base-building connections. | Fixtures move or are added, washrooms change, or the new operation creates different plumbing/servicing requirements. |
| Ceiling & building systems | Ceiling layout, HVAC distribution, sprinklers/fire alarm, lighting and service zones. | New rooms/ceilings/equipment require affected systems to be relocated or re-coordinated by the responsible discipline. |
| Equipment & structural work | Floor/roof structure, existing openings, supports and available service capacity where relevant. | Heavy/fixed equipment, new openings, supports or other structural/material alterations are proposed. |
| Use, life safety & accessibility | Existing/proposed use information, occupant characteristics, exits and accessible features. | The alteration or business operation changes the code information the permit drawings must communicate—or the project crosses into a dedicated Change of Use review. |
This is also why not every fit-out needs architectural, structural, HVAC, plumbing, electrical and fire-protection work as one fixed bundle. The project-specific responsibilities should be identified from the delta.
Toronto’s current non-residential interior-alteration guide requires permit drawings to be prepared on standardized sheets, drawn to scale, fully dimensioned, signed and dated. The submission uses the current Application for a Permit to Construct or Demolish and, where applicable, designer information and professional-review forms.
The exact package still depends on the project. Existing and proposed floor plans, use information, life-safety details, reflected ceiling information, plumbing fixtures, construction details and affected consultant drawings should be included only where they are required by the actual fit-out scope.
Send project context first, the next step can then focus on scope, information gaps and the right page or service route.
Fit-out problems often start when one drawing or document is treated as the whole truth. The permit set should reconcile the business plan with the space that exists and the building rules that actually apply.
What the tenant wants the space to do: room program, staff/customer functions, fixed fixtures/equipment and the proposed work list. This explains the business intent but is not proof of existing conditions.
Current measurements, photos and reliable existing drawings establish what is physically there now. Old landlord or previous-permit plans remain useful only when they match the actual suite.
Tenant-construction criteria, base-building drawings and landlord comments define shared-system constraints and who is expected to provide or modify particular work.
The final permit/construction set translates the accepted scope into existing/proposed plans, code/life-safety information, construction details and affected discipline drawings required for the real project.
You do not need a finished permit package to start. The first review should establish what exists in the unit, what the new tenant wants to change and whether the project belongs in this general fit-out service or a more specific approval path.
These questions focus on generic leased-space fit-outs; sector-specific questions stay on the dedicated commercial service pages.
A tenant fit-out adapts a leased commercial unit for the tenant’s operation. It can range from limited partition or washroom changes to a more involved interior renovation with ceilings, building-system coordination, fixed equipment and life-safety information. The permit scope depends on what exists and what is changing.
Those terms often describe the same broad family of leased-space improvements. “Tenant improvement” and “leasehold improvement” describe work to adapt the leased premises; “commercial renovation” is broader but overlaps heavily when the project is an existing commercial interior. This general tenant fit-out service covers that shared scope when no dedicated business-use page is a better fit.
Usually not by itself. A lease plan may establish the tenant area and a planning layout, but permit drawings need reliable existing conditions plus the proposed construction, use/code information and affected building-system coordination required for the project. Landlord/base-building records should be checked against the actual unit.
Previous permits and drawings are valuable evidence, but they do not make new work automatically permit-free. Confirm that the records match the physical unit and that the new tenant’s layout, fixtures, equipment and business operation do not introduce material alterations or a different approval path.
The practical split depends on the lease, landlord construction rules and the actual building systems. Base-building items may remain with the landlord while interior tenant work is assigned to the tenant, but the interface should be confirmed before the permit drawings and contractor scope are finalized. iPermit does not provide legal lease interpretation.
A project can involve both fit-out construction and a Change of Use issue. If the approved existing use versus proposed use is the main uncertainty, the dedicated Change of Use Permit or Zoning Review service should lead that decision instead of burying it inside the fit-out page.
Send the address/unit and current use, proposed business, current plans/photos, landlord/base-building criteria, the proposed layout/work list and any existing zoning/permit/City comments. That is enough to decide whether this is a generic fit-out, a dedicated use-type project or a Change of Use/zoning problem before a fixed drawing package is assumed.
Review timing depends on the building, occupancy and scope. Some qualifying small commercial interior alterations can use Toronto’s Express Services stream, where the City currently targets review within three business days after the application is taken in. Eligibility is limited by factors such as occupancy, floor area, change of use, patron-area changes and active shell permits.
Projects outside Express Services are assigned to the applicable review stream. Toronto currently targets 15 business days for complete Small Building applications and 20 or 30 business days for complete Large or Complex Building applications. These targets do not include the time needed for feasibility, zoning, drawings, landlord coordination, consultant work, intake deficiencies or applicant revisions.
