One of the most common questions at the start of a staircase project: “Do I actually need a permit for this?” The answer depends on the scope of work — and it matters, because a staircase installed without a required permit must be disclosed on sale and can be ordered to be removed by a municipal inspector. Here is a clear guide to when a staircase building permit is required in Ontario, how long it takes to get one, and what the application needs to include.
For official information on building permits in Ontario, visit Ontario’s Building Permit portal. C.O.R.S Designs manages the permit application process for all staircase permit Ontario projects.
When a Building Permit Is Required for a Staircase in Ontario
| Scope of Work | Permit Required? | Notes |
|---|---|---|
| Refinishing existing treads (sand, stain, recoat) | No | Cosmetic only — no structural change |
| Recapping treads only (new treads, same stringers, same configuration) | No | Like-for-like material replacement — no structural or configurational change |
| Adding carpet to existing stairs | No | Cosmetic only |
| Replacing railing on existing staircase | Yes | Railing replacement is a structural change affecting the guardrail/handrail system |
| Adding balusters to existing railing | Depends on municipality | Some municipalities require, some do not. Confirm with your local building department. |
| Full staircase rebuild (new stringers, new layout) | Yes | Any structural change to the staircase requires a permit |
| Changing staircase configuration (straight → L-shaped) | Yes | Structural and configurational change |
| Changing from closed riser to open riser | Yes | Requires new tread depth confirmation (250 mm minimum for open riser) |
| Mono-stringer floating staircase (any) | Yes + P.Eng Letter | Structural engineering review required for permit application |
| New staircase in new construction | Yes (covered by building permit) | New build permit covers staircase; separate staircase permit not required |
Permit Application Timeline by Ontario Municipality
| Municipality | Typical Residential Interior Alteration Permit | Notes |
|---|---|---|
| City of Barrie | 4–8 weeks from complete application | Online application available. Complete submission required (drawings, engineer’s letter for mono-stringer). |
| Town of Innisfil | 3–6 weeks | Typically faster than Barrie for interior alterations |
| Town of Collingwood | 4–8 weeks | Heritage properties may require additional review |
| City of Orillia | 4–6 weeks | Standard residential interior alteration review |
| Town of Bradford West Gwillimbury | 3–6 weeks | Active development municipality — review capacity varies by season |
| Town of Newmarket | 4–6 weeks | Online portal available for residential permits |
| City of Toronto | 6–12 weeks | Higher volume; expect longer timelines |
All timelines are for complete applications — incomplete submissions are returned, resetting the clock. C.O.R.S prepares complete permit packages on the first submission.
What the Permit Application Must Include
For a full staircase rebuild or mono-stringer floating staircase in most Ontario municipalities:
- Floor plan showing staircase location — existing and proposed, dimensioned
- Staircase section drawing — showing all rise and run dimensions, headroom clearance, landing dimensions
- Staircase elevation drawing — showing handrail height, guardrail height, railing infill configuration
- Structural engineer’s letter (mono-stringer designs) — stamped P.Eng letter confirming beam size, connection details, deflection under OBC design live load
- Specification notes — materials, tread species, finish, hardware
C.O.R.S prepares the complete permit drawings package and manages the application submission on your behalf for all projects in our service area.
What Happens If You Don’t Get a Required Permit
A staircase installed without a required building permit in Ontario:
- Must be disclosed to buyers in a real estate transaction. Failure to disclose is actionable misrepresentation.
- May be ordered to be removed or modified by a building inspector if discovered — typically during a sale inspection or a building department complaint.
- Voids the manufacturer’s warranty on some products (glass railing systems, in particular, require permit-inspected installation for warranty claims).
- May affect homeowner’s insurance coverage for incidents involving the staircase if the installation was not permit-inspected.
The cost and disruption of a retroactive permit or a removal order exceeds the cost of getting the permit right at the start. C.O.R.S does not install staircases that require a permit without one.

Frequently Asked Questions
Do I need a permit to replace my staircase railing in Ontario?
Yes, in most Ontario municipalities. Railing replacement affects the guardrail and handrail system — a structural element with specific OBC requirements. The permit application confirms the new railing meets OBC Part 9 guardrail height (920–1,070 mm), handrail height (865–965 mm), and infill gap (100 mm maximum) requirements.
How long does a staircase building permit take in Barrie?
The City of Barrie typically issues residential interior alteration permits within 4–8 weeks of a complete application. An incomplete application is returned — resetting the clock. C.O.R.S prepares the complete drawings and engineer’s letter package on the first submission to avoid delays.
Who applies for the staircase permit — the homeowner or the contractor?
Either can apply. In practice, C.O.R.S applies on behalf of the homeowner for all Simcoe County and Barrie-area projects. The permit is issued to the property address, not to the contractor.
Does recapping stairs (new treads on existing stringers) require a permit in Ontario?
No — tread replacement on existing stringers without changing the configuration, the railing, or the stringer structure is not a structural alteration and does not require a permit in most Ontario municipalities. Confirm with your local building department for your specific project.
What a Staircase Building Permit Application Must Include in Ontario
A complete staircase building permit application in Ontario typically requires:
- Permit application form: Available from your local building department (City of Barrie, County of Simcoe, or the relevant municipality)
- Site plan or location sketch: Showing where the staircase is located within the building footprint
- Floor plans: Showing the stair opening dimensions, floor-to-floor height, and the adjacent rooms
- Construction drawings: Detailed drawings showing rise, run, headroom, guardrail heights, and structural details. For floating staircases (mono-stringer or cantilevered systems), these must be P.Eng-stamped structural drawings
- P.Eng stamp (for floating systems only): A licensed Ontario P.Eng must sign and stamp the structural drawings for mono-stringer and cantilevered staircase systems. This confirms load path, steel specification, and structural compliance with OBC Part 4
- Permit fee: Typically $150–$400 for a residential staircase in Simcoe County municipalities
C.O.R.S prepares the permit application drawings as part of every staircase project. You submit the application to your local building department — we provide the technical documentation package.
Staircase Permit Timelines by Municipality in Simcoe County
| Municipality | Permit Application Processing | Notes |
|---|---|---|
| City of Barrie | 4–8 weeks (residential interior alteration) | Complete applications processed faster; incomplete applications returned |
| Town of Innisfil | 5–8 weeks | Similar to Barrie; Friday Harbour projects may require additional documentation |
| Town of Collingwood | 4–7 weeks | Blue Mountain area projects may fall under Town of The Blue Mountains jurisdiction |
| Town of Midland | 4–8 weeks | County of Simcoe building department handles some area permits |
| Town of Wasaga Beach | 5–9 weeks | Seasonal demand peaks in spring can extend timelines |
| Township of Essa (Angus) | 4–6 weeks | Smaller municipal office; typically efficient for residential applications |
| Town of Bradford West Gwillimbury | 4–7 weeks | One of the higher-volume permit offices in Simcoe County |
Important: These are estimated timelines for complete applications. An incomplete application (missing drawings, incorrect forms, or missing P.Eng stamp where required) will be returned and the timeline clock resets. C.O.R.S’s permit packages are prepared to be complete on first submission.
Consequences of Installing a Staircase Without a Required Permit in Ontario
Installing a staircase that requires a building permit without obtaining one creates four specific problems for Ontario homeowners:
- Real estate disclosure requirement: Ontario’s real estate disclosure rules require vendors to disclose unpermitted work that affects the property. A floating staircase installed without a permit is an unpermitted structural alteration — a disclosed defect that reduces buyer confidence and may require remediation before sale.
- Insurance coverage gap: Homeowners insurance may not cover claims that arise from or involve unpermitted structural work. If a staircase-related incident occurs, the unpermitted installation could provide the insurer grounds to deny or reduce the claim.
- Municipal enforcement: Building inspectors have the authority to issue an Order to Comply, which can require the homeowner to expose the structural work for inspection (removing drywall, finishes), obtain a retroactive permit, or in some cases, remove the non-compliant structure entirely.
- Warranty implications: C.O.R.S’s installation warranty is conditional on the project being completed with the required permits and inspections. We do not install floating staircase systems without the required permit and P.Eng stamp.
How C.O.R.S Handles the Permit Process for Staircase Projects
C.O.R.S is responsible for the technical documentation; you are responsible for submitting the application (as the property owner) and paying the permit fee. Here is how the permit process works on a C.O.R.S project:
- On-site assessment: During the initial consultation, we determine whether your project requires a permit based on scope of work and structural system type
- Shop drawing preparation: Our draftsperson produces the construction drawings required for the permit application, including floor plans, elevations, and structural details
- P.Eng review and stamp: For floating staircase systems, our structural engineer reviews the drawings, calculates load paths, and stamps the structural drawings — included in your C.O.R.S quote at no additional charge
- Documentation package handoff: We provide you with a complete permit application package including all required drawings
- You submit the application: The property owner submits the permit application and pays the municipal fee
- Permit issued — fabrication begins: C.O.R.S begins fabrication after permit issuance confirmation. On-site installation is scheduled after fabrication (typically 2–3 weeks after permit)
- Post-installation inspection: After installation, the building department schedules a final inspection. C.O.R.S’s designs pass first inspection consistently across all Simcoe County municipalities
