Commercial Renovation & Tenant Improvement Permit Drawings
The service is matched to the actual project, municipality and information available before detailed permit documentation is finalized.
What does this service need to solve?
A commercial fit-out can require a building permit even when the exterior and floor area stay unchanged. The permit review can involve use/occupancy, exits, fire/life-safety, accessibility, plumbing, HVAC/mechanical and other affected systems.
Commercial and industrial permit drawings need to describe the actual existing and proposed use, layout, exiting, accessibility and affected building systems. A tenant plan alone is not necessarily a complete permit package.
What changes the scope of Commercial Renovation & Tenant Improvement Permit Drawings?
The same project name can require different drawings and approvals on different properties. These four checks help define the real permit problem before the set is developed too far.
Existing & proposed use
The current approved use and proposed occupancy can change zoning, life-safety and permit requirements.
Exiting & life safety
Travel paths, exits, fire separations and occupant-related requirements can shape the layout.
Accessibility
Barrier-free paths, entrances, washrooms and other accessibility requirements can affect the design.
Building systems
HVAC, plumbing, electrical/lighting, structural or fire-protection information may need separate coordination.
What the project package may need to communicate
The exact documents depend on the property, building, proposed work, municipality and professional scope. A coordinated set should explain the work clearly enough for the applicable review.
Existing / proposed layout
Identify suite boundaries, uses, partitions, doors, rooms and key dimensions.
Occupancy & life-safety notes
Document the permit information needed to explain exiting, separations and proposed use.
Accessibility information
Show relevant barrier-free paths, entrances, washrooms and clearances where applicable.
Building-system coordination
Coordinate affected HVAC, plumbing, lighting/electrical and other building systems.
Structural information
Address new openings, framing or loading changes through the appropriate responsible professional.
Permit / application documents
Coordinate the drawings and supporting municipal information included in the written scope.
Commercial building permit drawings for renovations need to describe the proposed use and construction, not only the tenant layout. Exits, accessibility, washrooms, fire/life-safety and affected building systems can all change the permit scope.
Commercial Renovation & Tenant Improvement Permit Drawings: project-specific permit considerations
Commercial permit drawings for tenant fit-outs and interior renovations
A commercial permit drawing, tenant improvement permit, tenant fit-out drawing or interior renovation permit must describe the actual existing and proposed use, floor layout, life-safety conditions and work being changed—not just the furniture plan.
For a use change, start with Change of Use Permit & Occupancy Review before assuming an interior alteration alone is sufficient.
What a commercial tenant-improvement package can include
Depending on the building, use and agreed scope, 828 Design can prepare and coordinate:
- existing and proposed floor plans with room/use labels and key dimensions
- partition, door, ceiling and interior construction information
- exit, occupant-load and fire/life-safety information required for the permit
- barrier-free/accessibility layouts and washroom alterations where applicable
- plumbing, HVAC/mechanical and Building Code-related lighting/power information within applicable registered scope
- building-structural information within applicable scope and coordination of separately regulated professional input where required
What we check before the tenant layout is locked in
The lease area may look suitable, but the proposed business use can change what the building needs.
- whether the proposed use is permitted by zoning and whether a change-of-use review is triggered
- existing permit history, current recognized use and available base-building information
- number and arrangement of exits and travel paths
- washrooms, barrier-free path of travel and accessibility implications
- fire separations, alarm/sprinkler conditions and other life-safety systems affected by the work
- plumbing, ventilation/HVAC, structural or other technical changes required by the proposed operation
Commercial fit-out versus change of use
A unit can be renovated without changing its use, or the new tenant can trigger a change in how the space is classified or used. Ontario’s Building Code Act can require a change-of-use permit even where no construction is proposed if the change results in an increase in hazard. We therefore confirm the existing and proposed use before treating a project as a simple renovation.
After the commercial permit is issued
The contractor should build from the approved permit documents and arrange the required inspections. Material changes to layout, exits, fire/life-safety systems, plumbing, HVAC/mechanical or structure should be reviewed before they are constructed because revised permit information may be required.
How the permit drawing service moves forward
A clear sequence helps separate feasibility, design, documentation and municipal review without implying that any approval result is guaranteed.
Property / Project Review
Review the address, proposed work or use, available drawings and the main zoning/permit questions.
Existing Information
Confirm the measurements, survey/base-building information, photographs or consultant inputs needed for the accepted scope.
Permit Documentation
Prepare and coordinate the drawings and supporting information included in the written service agreement.
Submission / Review
Support the agreed municipal submission or comments process; added revisions and new requirements are handled as separate scope where applicable.
What to send for a project review or quote
Good starting information helps identify the correct service and avoids guessing about the building or property.
- property address, unit number and municipality
- business name and clear description of the proposed use
- existing floor plan, landlord/base-building drawings or prior permit plans if available
- photos of the full tenant unit, entrances, exits, washrooms and mechanical areas
- approximate unit area and desired room/layout program
- any landlord criteria, city comments, zoning review or existing permit information
The issued permit is the construction reference.
Contractors and owners remain responsible for construction, site safety, inspections and building in accordance with the issued permit documents. Material field changes should be reviewed before they are constructed because revised drawings, engineering or municipal approval may be required.

Short answers first, with project-specific limits stated clearly.
Do I need a permit if I am only changing the interior?
Possibly. Interior work involving partitions, exits, washrooms, building systems, structural changes or other regulated construction can require a permit even when the exterior is untouched.
Can I sign a lease before checking whether my business use is allowed?
You can, but from a project-risk standpoint the use and zoning should be checked early. A space that worked for the previous tenant may not automatically work for a different business.
Can the landlord’s old drawings be used?
They are useful reference material, but the existing conditions and current permit information still need to match the space being designed.
Will accessibility upgrades be required?
They can be triggered by the extent and type of alteration and by the existing building. We review the applicable barrier-free requirements rather than assuming the existing layout can remain unchanged.
Do I need separate HVAC, plumbing or structural information?
It depends on what the fit-out changes. We coordinate applicable technical permit information within our registered qualifications and identify separate professional responsibility where required.
Can construction start while the permit is under review?
Permit-required work should not begin before the permit is issued. Starting early can create enforcement, inspection and redesign problems.
What information should I send for a commercial permit quote?
Send the property and unit address, existing and proposed business use, a short scope description, landlord/base-building information if available, photos and any existing drawings or municipal comments.
Can the proposed business use change the permit requirements?
Yes. Use and occupancy can affect zoning, exiting, fire/life-safety, accessibility, washrooms and technical requirements even when the construction appears minor.
