Industrial design and permit drawings in Toronto.
We design industrial unit alterations, additions and new buildings where the whole building, after the work, stays within 3 storeys and 600 m², with engineers on the structure and systems. Past either limit an architect or engineer designs it. We check that, and site plan approval, first.
What are you planning?
Three kinds of industrial work, each with its own page.

Does this sound like my property?
Most industrial projects start with one of these.

A new industrial building
You are putting up a new industrial, manufacturing or warehouse building and need to know whether it needs an architect, an engineer or site plan approval.

An addition to your building
You are adding to an existing industrial building and want to know whether the addition stays inside the City's site plan exemption.

Fitting out or converting a unit
You are fitting out or converting an industrial unit and need building permit drawings for the work.

Engineers in one permit set
Your project needs engineers for structure, HVAC, plumbing or sprinklers, and one office to pull their drawings and ours into a single submission.
Does my project need an architect?
It depends on the size and use of the whole building.

No architect needed
We design it
- A building of up to 3 storeys and 600 m², used for industry, offices or shops.
- Interior work in a building of any size, when it leaves the structure, fire separations, exits, the main entrance and outside walls alone, and adds no floor space.

Past the line
An architect or engineer designs it
- A building of more than 3 storeys or 600 m².
- A building made to house an engineered process, at any size: a professional engineer designs it.
Not sure which side yours is on? We check it from the survey before any drawing starts.

The Architects Act lets a designer who is not an architect design an industrial building of up to 3 storeys and 600 m² of gross area: every floor above grade of the whole building, after the work. Past either limit an architect or a professional engineer must design it. In a bigger building, a designer like us may still draw interior work that does not affect the structure, a fire safety system or fire separation, a main entrance, public corridor or exit, or an exterior wall, and adds no floor area.

P.28, s. 12(4) (e-Laws) (opens in a new tab)Toronto Building requires a permit to construct, add to or demolish a building, and says a change of use needs one even when no construction is proposed. The Building Code Act ties a change-of-use permit to whether the change increases the hazard, so confirm with the City before relying on an exception.

A new industrial, manufacturing or warehouse building is exempt when all such buildings on the lands total no more than 2,000 m² of gross floor area, or the zoning maximum if greater; none is an asphalt, cement or concrete batching plant, recovery or recycling facility, salvage yard or waste transfer station; and none has a use that Zoning By-law 569-2013 permits only with conditions, where that by-law applies.

Even an exempt building or addition needs approval where the Official Plan requires a road or lane widening, or where the Chief Building Official finds safety, access or neighbouring-land matters to secure; it may also be required near a railway line, a wetland, the Great Lakes shoreline, an inland lake or a river or stream valley.

Exterior finishes, openings and how close they can sit to the property line, overall height, floor-to-floor heights, stairs and guards.
Wall, floor and roof assemblies, a typical wall section, guard details, door and room finish schedules.
Structure by a professional engineer; heating, cooling and ventilation by a mechanical engineer or a designer registered in Building Services; plumbing, sprinklers and fire alarm by their engineers or registered designers; racking with raised platforms or walkways by an engineer, as the Building Code requires. Checked against our sheets so the set goes in as one.
- Zoning review: size, use and site plan check
From the survey and any existing drawings we confirm the zoning, the proposed use, the whole building's storeys and gross area after the work, and whether the work falls inside one of the City's site plan exemptions.
- Engineers lined up
The engineers for the structure and building systems, and an architect where the law requires one, are brought in and their scope agreed before drawing starts.
- One coordinated permit set
Our sheets and the engineers' drawings (structure, HVAC, plumbing, fire protection) checked against each other, with the forms Toronto Building asks for.
- Submit and answer
We file the application and answer every question from the City's examiner until the City decides.

Rocco was efficient and effective. He worked closely with us to ensure the design meets our needs and recommended valuable solutions that we previously weren't aware of. We got the permit within a reasonable amount of time despite submitting it just before the holidays.

Questions before you send it
Do I need an architect or an engineer?
Not for the building design, if the whole building after the work stays within 3 storeys and 600 m² of gross area (every floor above grade) and is not built to house an engineered process. Past either limit an architect or a professional engineer must design it and review the construction. In a bigger building we can still draw interior work that leaves the structure, fire separations, exits and exterior walls alone. Either way the structure is designed by an engineer or a designer registered in Building Structural, and racking with raised platforms or walkways for staff by an engineer.
Does my industrial project need site plan approval?
Not always. A new industrial, manufacturing or warehouse building can be exempt when all such buildings on the lands stay within 2,000 m² of gross floor area (or the zoning maximum, if greater) and none of the excluded uses apply. Additions can be exempt up to the greater of 25% of the existing industrial floor area or 1,000 m². Approval can still be required for a road widening, for safety or access matters the City wants to secure, or near a railway, ravine or the lake. We check this first, from your survey and the zoning.
Do I need a building permit for a change of use with no construction?
Toronto Building says yes, even when no construction is proposed. The Building Code Act ties it to the hazard: the Building Code's change-of-use table marks which changes need one, so confirm with Toronto Building before relying on an exception. If the change comes with alterations, their building permit covers it.
Who designs the HVAC, plumbing and sprinklers?
Engineers, or designers registered in the Building Code's classes for that work: Building Services for heating, cooling and ventilation, Plumbing – All Buildings, and Fire Protection. The firm's HVAC class, HVAC-House, covers houses only. We coordinate their drawings with ours so the set goes in as one.
Who signs the drawings?
Our drawings carry BCIN 25897 – 41741; Ontario's registry lists the firm's classes as House, Small Buildings, Large Buildings and HVAC-House. Where the law requires an architect or engineer, they design that work and sign the Commitment to General Reviews.
What does the City charge?
Toronto Building's 2026 rate for a new industrial building or addition under 7,500 m² is $17.01 per m² finished or $12.37 per m² as a shell. Interior alterations in industrial space are $11.53 per m² of the area of work, with a $214.79 minimum for any permit. Toronto's development charges exempt industrial uses. Our fee is separate and quoted in writing.
