GETSUP buyer guide · Last reviewed September 18, 2026
Calling a shelter temporary, portable, fabric-covered or seasonal does not by itself answer whether a permit is required. The local authority reviews the actual structure, size, use, duration, location, attachment and applicable law.
The safest purchasing sequence is to identify the exact model and site, then obtain written direction from the municipality before committing to foundation work or installation.
Quick answer
Ask the local building and zoning departments about the exact shelter size, use, duration, setbacks, location, foundation, anchoring, fire access and engineering documents. Do not rely on a supplier’s general “no permit” statement. Any exemption must match the project and local requirements.
Why the answer varies
- Municipality and zoning designation
- Aggregate ground area and building dimensions
- Whether the shelter is attached to another building
- Distance to buildings, property lines, fire routes and utilities
- Commercial, industrial, agricultural, residential or assembly use
- Seasonal dates and total installation duration
- Foundation, anchoring and connection to containers or other structures
- Public access, occupancy, stored materials and fire load
- Availability of drawings, flame documentation and Ontario engineering review
A provincial example is not a universal exemption
Ontario municipalities publish guidance based on the Building Code and local rules. For example, Toronto states that a tent or group of tents may be exempt from a building permit when the aggregate ground area is not more than 60 m², it is not attached to a building and it is more than 3 m from other structures. Toronto also notes that zoning compliance can still be required and publishes separate rules for seasonal plastic-sheet-covered accessory structures.
Do not automatically apply those examples to a commercial storage shelter, a different municipality or a different use. Ask the authority to classify the proposed structure and identify the documents it requires.
Information package for the municipality
| Document/data | What to include |
|---|---|
| Site plan | Property lines, existing buildings, shelter location, dimensions, setbacks, fire route, access and utilities |
| Product drawings | Plan, elevations, cross-sections, doors, frame/truss, connections and cover |
| Use statement | What will be stored, whether people work inside and hours/season of use |
| Foundation/anchors | Substrate, anchor type, layout and connection details |
| Structural information | Model-specific snow/wind data and any sealed calculations or drawings |
| Material documentation | Cover specification and any requested flame/fire documentation |
| Project schedule | Installation and removal dates if truly seasonal or temporary |
Questions to ask in writing
- How will this exact structure and use be classified?
- Is a building permit required? If not, which exemption applies?
- Does zoning permit the use and proposed location?
- What setbacks, lot coverage, height or parking rules apply?
- Are site-plan, conservation, fire, electrical or other approvals required?
- Must drawings or calculations be prepared or reviewed by an Ontario professional?
- What foundation and anchoring information is required?
- Are inspections required before occupancy or use?
- Do seasonal installation dates or removal conditions apply?
- What changes would require a revised permit or new review?
Purchase contract safeguards
Separate product supply from permit approval. A supplier can provide available drawings and specifications, but the property owner or applicant normally remains responsible for site information, applications and compliance unless a written contract clearly assigns a professional service.
Before paying a non-refundable amount, identify what happens if the municipality requires a different foundation, Ontario-sealed drawings, a smaller structure or refuses the proposed use. Record who pays for redesign, storage, freight changes and cancellation.
Permit-ready project sequence
| Step | Action | Decision gate |
|---|---|---|
| 1 | Measure site and define use | A complete site/use brief exists |
| 2 | Select a candidate exact model | Drawings and specifications are available |
| 3 | Contact building and zoning authorities | Written project-specific requirements received |
| 4 | Obtain required professional design/review | Foundation, anchors and structure meet the submission basis |
| 5 | Submit and obtain approvals | Conditions understood before installation |
| 6 | Finalize product and installation order | Delivered configuration matches approved documents |
| 7 | Inspect and document installation | Required sign-off and ongoing maintenance plan complete |
Frequently asked questions
Does a temporary storage shelter need a permit?
It may. “Temporary” is not a complete exemption. Size, use, location, attachment, duration and municipal rules must be checked for the exact project.
Does a fabric building count as a building?
The authority having jurisdiction determines classification under the applicable code, zoning and local rules. Ask before purchase or installation.
Are shelters under 60 m² always permit-free in Ontario?
No universal conclusion should be drawn. Toronto publishes a specific tent exemption with additional conditions, but classification, zoning and local requirements still matter and other municipalities may apply different processes.
Do agricultural shelters have different rules?
Agricultural use can affect zoning or code classification, but it does not eliminate the need to obtain project-specific municipal guidance.
Do shipping-container shelters need permits?
They may require review of the canopy, containers, connections, foundations, use and zoning. Treat the complete assembly as the project.
Will foreign engineering drawings be accepted?
The municipality may require design or review by an Ontario-qualified professional and project/site-specific information. Ask what form, seal and scope are required.
Can GETSUP guarantee permit approval?
No supplier can guarantee a municipal decision without the authority’s review. GETSUP can identify available product documents for a candidate model so the buyer can seek approval.
Should I install before the permit decision?
Installing first can create enforcement, redesign, removal and cost risk. Complete the required review and approval process before foundation work or installation.
