01 / USE FIRST
Use, Zoning & Change of Use
For locations where the main uncertainty is whether the proposed operation is permitted or whether the existing approved use needs to change.

Commercial Building Permit Services for Toronto Business Spaces
Opening, renovating or taking over a commercial unit? iPermit helps identify whether the space and proposed operation point to a tenant fit-out, change of use, specialized permit or zoning review, then coordinates the permit documents and municipal submission within the agreed scope.
◆ Route by business use and scope
Choose the Commercial Permit Path That Matches the Operation
The hub should not make a restaurant, clinic and office sound like the same permit assignment. Start with the business use below; each route has its own code, servicing and approval questions.
02
Food & Beverage
Food-service spaces can add kitchen exhaust, plumbing, grease/interceptor, fire/life-safety, Public Health and licensing considerations beyond a standard retail fit-out.
03
Office, Retail & General Fit-Out
For tenant improvements involving partitions, exits, washrooms, accessibility, ceilings and coordinated building-system changes without a more specialized business use.
04
Medical, Dental & Child Care
Clinical and child-care uses can introduce specialized plumbing, equipment, accessibility, occupant-load, life-safety or operational approval questions.
05
Automotive & Specialized Uses
Vehicle-related and unusual commercial operations should be checked for zoning, ventilation, drainage, fire-safety and licensing constraints before the layout is assumed feasible.

Send project context first, the next step can then focus on scope, information gaps and the right page or service route.
Before You Design the Fit-Out, Confirm What the Unit Is Approved For
A vacant or previously occupied commercial unit is not automatically ready for the next business. The fastest way to choose the right permit service is to compare the existing approved use, the proposed operation, the physical work and the landlord/base-building information before the layout is treated as final.
| Question | Why it changes the permit route | Likely next step |
|---|---|---|
| Is the proposed business use different from the approved use? | A new major occupancy or use can trigger a change-of-use review even when the space already looks finished. | Check the Change of Use Permit route. |
| Is the use allowed at this address? | Zoning can stop a location before the fit-out drawings matter. Some business-licence categories also need zoning confirmation. | Use Zoning Review or Business Licence Zoning Review. |
| Are you changing partitions, exits, washrooms or building systems? | Toronto’s non-residential alteration permit covers interior alterations where floor area does not increase; the building use may also change. | Route to the commercial fit-out page that matches the operation. |
| Do the landlord drawings and permit records match the current unit? | Old leasing plans can omit later alterations, open permits or base-building conditions that affect the tenant design. | Start with the existing file and identify missing information before permit drawings are finalized. |
◆ Lease risk comes before permit paperwork
A Signed Lease Does Not Confirm the Unit Is Permit-Ready
A commercial lease does not guarantee that the space is ready for the proposed business. Zoning, change-of-use, base-building, or permit issues can still affect the project.
Before finalizing the fit-out, review the approved use, proposed operation, landlord drawings, open permits, and likely construction scope.
iPermit helps identify the permit and property requirements that should be understood before the budget and opening timeline are finalized.
Building Permit, Business-Licence Zoning and Occupancy Are Different Reviews
1. Building permit / zoning clearance: Toronto Building requirements depend on the review stream. Small Building and Large/Complex applications currently require an issued Zoning Applicable Law Certificate for completeness, while eligible smaller commercial interior alterations may qualify for Express Services with separate submission requirements.
2. Zoning Review for Business Licence: some Toronto licence categories require written zoning confirmation. The City also states that if building alterations or a new major occupancy are proposed, a building permit may be required in addition to the licence-related zoning review. See the Toronto business-licence zoning review.
3. Authority to Occupy: this is not a generic certificate that every finished business requests. Toronto uses Authority to Occupy for partial occupancy of an unfinished Part 3 building after consultation with the building inspector and when the building is ready for that permit. See the Toronto Authority to Occupy guidance.
Toronto review timing also depends on the applicable stream. The City currently targets three business days for eligible Express applications, 15 business days for complete Small Building applications and 20 or 30 business days for complete Large or Complex Building applications. These are municipal review targets, not total project timelines.

Already Have Landlord Drawings, an Old Permit Set or City Comments?
Send the complete material rather than a single leasing plan or examiner comment. A commercial permit file often depends on what was previously approved for the unit and what the base building can support.
Useful documents include:
- current lease or landlord plan showing the unit boundaries;
- previous permit drawings or occupancy/use information, if available;
- base-building architectural, HVAC, plumbing, sprinkler or electrical information supplied by the landlord;
- your proposed layout and equipment list;
- the municipal application number and complete review comments if a file already exists; and
- photos of the current unit and any construction already completed.
iPermit does not automatically adopt responsibility for drawings prepared by another designer or professional. The first review identifies which information can be relied on, what needs to be verified and which parts of the new application fall within the proposed iPermit scope.
◆ Start with the business, not a standardized service bundle
What to Send for a Commercial Permit Review
You do not need finished permit drawings for the first review. The most useful starting information is what the unit is today, what the business will do, what construction is proposed and where the lease/opening timeline currently stands.

◆ Commercial permit questions
Commercial Building Permit FAQs
These answers cover hub-level decisions. Detailed restaurant, change-of-use, clinic and fit-out requirements stay on their dedicated service pages.
Does every commercial renovation need a building permit in Toronto?
No. Cosmetic maintenance is not the same as a material alteration. Toronto requires permits for construction and material alterations, and its non-residential interior-alteration guide covers interior work where floor area does not increase. The actual permit scope depends on the proposed use and work.
What is the difference between a tenant fit-out and a change of use?
A tenant fit-out describes the construction for the tenant. A change of use addresses how the building or unit will be occupied. The same project can involve both, or a fit-out can proceed without a change of use when the approved occupancy/use remains appropriate.
Should I review permits before signing a commercial lease?
Permit and zoning feasibility should be investigated before the business becomes dependent on an unconditional location commitment. That review does not replace commercial legal advice, but it can identify use, base-building and permit issues that affect the fit-out and opening plan.
Does a building permit include the Toronto business licence?
No. Building permits and business licences are separate approval systems. Some Toronto licence categories require a Zoning Review for Business Licence, and building alterations or a new major occupancy can also require a building permit.
What if the landlord only has old or incomplete drawings?
Old drawings are a useful starting point but should not automatically be treated as current approved conditions. Send the complete landlord/base-building material so the first review can identify what is reliable and what still needs to be verified.
Can iPermit help with a commercial permit already under review?
Yes, depending on the file and agreed scope. Send the complete submitted package, application number and all current review comments. iPermit will first identify which comments fall within its services and whether existing third-party documents can be continued or require another responsible designer/professional.
