When a Building Permit Is Required for a New Staircase in Vancouver

A steel staircase looks simple on paper. Two stringers, a set of treads, some guardrail, done. But the moment you start changing stair locations, cutting into floor framing, or adding a new opening between levels — the City wants to see drawings. And they want a permit.

We fabricate and install custom metal staircases across Vancouver, Burnaby, North Vancouver, Coquitlam, and New Westminster. Permit coordination is part of almost every staircase job we do. Here is what actually happens when a building permit enters the picture — the triggers, the process, the costs, and the places where projects get stuck.

When You Need a Building Permit for a Staircase

Not every staircase job triggers a permit. Refinishing treads, swapping out a handrail, or bolting on a new set of balusters — that is cosmetic work. The building department does not care about cosmetic work.

But the line between cosmetic and structural is sharper than most homeowners realize. Here are the situations that pull a permit into the scope:

New staircase construction. Any staircase built as part of a new home, addition, or renovation that adds floor area will need a building permit. Full stop.

Relocating an existing staircase. Moving a stair even a few feet usually means cutting new floor openings, modifying structural framing, and rerouting the load path. That is structural work — it needs a permit and typically an engineer.

Changing the staircase configuration. Going from a straight run to an L-shaped stair with a landing. Converting a closed stair to an open mono stringer design. Widening the stair opening. All of these change the structural interaction between the stair and the building frame.

Any work that touches load-bearing walls or floor joists. If you need to cut, relocate, or reinforce framing to make the stair fit — permit required.

Adding or modifying a guardrail system where none existed. This one catches people off guard. If the existing stair had no guardrail and the renovation triggers code review, the new guardrail needs to meet current BC Building Code standards.

The pattern is straightforward. If the work changes how loads move through the building, or if it creates a new opening in a floor assembly, it needs a permit.

BC Building Code Requirements for Stairs

The permit is not just a formality. The building inspector will check your staircase against specific dimensional requirements in the BC Building Code. These numbers drive the shop drawings and fabrication — get them wrong and the stair fails inspection.

Maximum riser height: 200 mm. Every riser in the stair must be at or below this. And all risers must be uniform — the code allows a maximum 5 mm variation between the tallest and shortest riser in a flight.

Minimum tread depth (run): 235 mm. This is the horizontal distance from nosing to nosing. Not the total tread width — the run. On a steel stair with open risers, the tread must also have a nosing projection or be deep enough to prevent foot slip-through.

Minimum stair width: 860 mm. Clear width, measured between the guardrails or finished walls. Not the rough opening — the usable walking width. On residential stairs, 860 mm is the minimum. Most of the custom stairs we build for homes in Vancouver and Burnaby land between 900 mm and 1,000 mm because a wider stair simply feels better to use.

Guardrail height: 900 mm minimum at stairs, 1,070 mm minimum at landings, balconies, and open sides more than 600 mm above the adjacent surface. The guardrail must resist a specified horizontal load — this is where structural steel and proper connection detailing matter.

The 100 mm sphere rule. No opening in the guardrail can allow a 100 mm sphere to pass through. This is a child-safety requirement and it affects everything from picket spacing to glass panel design to cable rail layouts. We detail every guardrail assembly against this rule before fabrication starts.

Headroom: 1,950 mm minimum. Measured vertically from the nosing line to the ceiling or any obstruction above. Low headroom is one of the most common problems on renovation stairs — especially when the stair opening size is constrained by existing framing.

These are residential numbers. Commercial stairs have different requirements for width, egress capacity, and fire separation. If your project falls under Part 3 of the code — anything over 600 square metres or three storeys — the stair requirements change significantly.

The Permit Process: Vancouver vs. Burnaby vs. Other Municipalities

Here is where it gets interesting. Every municipality in Metro Vancouver runs its own building department with its own intake process, review timelines, and plan-check expectations. The BC Building Code is provincial, so the dimensional rules are the same everywhere. But the administrative process is not.

City of Vancouver

Vancouver has one of the more structured permit processes in the region. For a residential staircase that involves structural changes, expect to submit:

• Architectural drawings showing the stair layout, dimensions, and floor plan context
• Structural drawings — typically engineer-stamped — showing the stair connections, floor opening reinforcement, and guardrail attachment details
• A completed building permit application with the project address, scope description, and owner authorization

Review timelines for residential alterations in Vancouver typically run 4 to 8 weeks from submission to permit issuance. Straightforward stair replacements on the shorter end, full renovations with structural changes on the longer end. Permit fees for residential work generally land between $150 and $500+, depending on the declared construction value.

And here is the part that slows people down: incomplete submissions. If the plan checker opens your package and the structural details are missing, or the stair dimensions are not clearly noted, the application goes into a correction cycle. That can add 2 to 4 weeks to the timeline.

City of Burnaby

Burnaby’s process is similar in scope but tends to move a bit faster for straightforward residential permits. Our shop is based in Burnaby on Douglas Road, so we deal with this building department regularly. The submission requirements are the same — architectural plans, structural drawings where applicable, and a completed application. Fees are in a comparable range.

One difference: Burnaby’s residential plan-check team is smaller, which means the queue can be shorter — but it also means a single correction request backs things up more noticeably.

Coquitlam, New Westminster, and North Vancouver

Each runs its own building department. The BC Building Code applies uniformly, but submission formats, online portal systems, and review queue lengths vary. For staircase work in these municipalities, we coordinate with the homeowner’s contractor or architect to confirm exactly what the local building department expects before we finalize shop drawings.

The key takeaway across all municipalities: submit complete, accurate drawings the first time. A clean submission with engineer-stamped structural details, correct stair dimensions, and clear guardrail specifications will move through review faster than a rushed package that triggers correction requests.

What Drawings Are Needed

A building permit application for a staircase is only as good as the drawings that support it. Here is what the plan checker wants to see:

Floor plans showing the stair location, the floor opening size, and the relationship to adjacent rooms. Before and after plans if it is a renovation.

Stair sections and elevations with riser heights, tread depths, total rise, total run, headroom clearance, and guardrail heights dimensioned clearly. The plan checker will measure these against the BC Building Code numbers listed above.

Structural details. If the stair is steel — and most of what we build is structural steel — the plan checker wants to see how the stringer connects at the top and bottom, how the floor opening is framed or reinforced, and how the guardrail posts are anchored. These details typically need to be prepared or reviewed by a professional engineer.

Guardrail details showing material, picket or panel spacing, connection method, and confirmation that the 100 mm sphere rule is met.

At Jeff and Simon, we produce detailed shop drawings for every staircase we fabricate. These drawings show exact steel member sizes, connection types, weld symbols, and finish specifications. Shop drawings are fabrication documents — they are not permit drawings on their own. But they feed directly into the permit package. When we coordinate early with the project architect or engineer, our shop drawings and their permit drawings stay aligned. That eliminates the back-and-forth that kills project timelines.

Engineer Involvement

Any staircase project that involves structural changes — new floor openings, modified framing, load-bearing wall alterations — will require a professional structural engineer. The building department wants to see engineer-stamped drawings confirming that the structural modifications are safe and code-compliant.

This is not optional and it is not something to defer. We have seen projects where the homeowner or contractor tried to submit permit drawings without engineering, got rejected, and then had to bring in an engineer after the fact. That adds weeks and sometimes forces design changes because the engineer identifies load path issues that the original layout did not account for.

The better approach: bring the engineer in at the design stage, before shop drawings are finalized. The engineer sizes the steel, confirms the connection details, and stamps the drawings. We fabricate to those specifications. The permit submission goes in clean. Everyone saves time.

Our shop is C.W.B. (Canadian Welding Bureau) certified, which means our welding procedures and quality systems meet national standards. When an engineer specifies weld types and sizes on the stamped drawings, the building department knows our shop can execute them to specification. That certification matters during inspection — it gives the inspector confidence that the fabrication quality matches what the engineer designed.

How to Avoid Permit Delays

Most permit delays on staircase projects come from the same handful of problems. Here is how to avoid them:

Do not start fabrication before the permit is issued. This sounds obvious, but it happens constantly. A homeowner gets excited about the stair design, the fabricator starts cutting steel, and then the permit review comes back with a required dimension change. Now you have steel that does not fit. We will not start fabrication on a permit-required staircase until the permit is in hand — or at minimum, until the structural design is locked and the engineer has signed off.

Confirm the stair dimensions against code early. Before the architect finalizes the stair layout, check the riser height, tread depth, width, and headroom against BC Building Code minimums. A 210 mm riser height might look fine on paper, but it exceeds the 200 mm maximum and the plan checker will flag it.

Submit complete packages. Missing structural details, unclear dimensions, or absent engineer stamps are the top reasons applications go into correction cycles. A clean, complete first submission is the single biggest factor in hitting a 4-week review timeline instead of an 8-week one.

Coordinate between trades early. On a renovation, the staircase fabricator, the framing contractor, the architect, and the engineer all need to be working from the same information. If the framer builds the floor opening to one dimension and the stair fabricator details the stair to a different dimension, something will not fit. We coordinate with the project team from the quoting stage to make sure our shop drawings align with the architectural and structural intent.

What Jeff and Simon Handles

We are a fabrication and installation shop — not an architecture firm and not an engineering firm. But staircase work sits right at the intersection of all three disciplines, and we have been doing this long enough to know how the pieces fit together.

Here is what we do on a typical permitted staircase project:

1. Site review and quoting. We look at the existing conditions, discuss the design intent, and provide a detailed quote for fabrication and installation. If we see potential permit triggers, we flag them at this stage.

2. Shop drawing production. We produce detailed fabrication drawings showing every steel member, connection, and dimension. These drawings coordinate with the architect’s and engineer’s permit drawings.

3. Fabrication. All steel fabrication happens in our C.W.B. certified shop in Burnaby. Mono stringers, double stringers, landings, guardrail posts, handrail — everything is built to the approved drawings.

4. Installation coordination. We schedule installation to align with the construction sequence — after the floor opening is framed and inspected, before the finishes go in.

5. Inspection support. When the building inspector shows up to check the stair, the steel is built to the stamped drawings, the dimensions meet code, and the welds are executed by certified welders. That makes for a smooth inspection.

We work with architects, general contractors, builders, and homeowners across Metro Vancouver. If you are in the early stages of a stair project and you are not sure whether a permit is required, get in touch with us. We can look at the scope and give you a practical read on what the permit path looks like before you commit to a design direction.
