Design-Build & Commercial Renovations in Saint-Laurent
Our office is at 8300 Chemin de la Côte-de-Liesse, Suite 209. Saint-Laurent isn't a market we drive into for a job and leave — it's where the studio has been based since 2002, and the one borough where “local” is literal.
Saint-Laurent went from the island's slowest permit borough to about average — a bigger deal than it sounds
Around 2010, Saint-Laurent was the worst borough in Montréal for permit delays — averaging 289 days, nearly ten months. By 2017 it had cut that to about 42 days, roughly the city average of the day. The story is the improvement, not a ranking: going from ten months to about six weeks is what changes how you plan a project here. When a borough clears permits in weeks, your design and documentation become the critical path — not the wait at the counter.
Figures from ~2010 and 2017; timelines have shifted since and vary by project — confirm the current figure with the borough.
Where a Saint-Laurent permit actually goes
Construction in the borough runs under the Règlement sur la construction et la transformation de bâtiments (08-004), administered by the Direction de l'aménagement urbain et des services aux entreprises — Division des permis et des inspections, 777 boulevard Marcel-Laurin. We build the drawing set to what that office expects, so the file clears the first time.
Current as of 2026 — confirm with the borough.
The scheduling trap that voids a Saint-Laurent permit
Two clocks run at once on a Saint-Laurent permit, and missing either one costs you the permit — which is how a permit expires before the first wall moves while you're waiting on financing, a signed lease, or a long-lead item:
- Valid for six months from the start of work.
- Work must begin within three months of issuance, or the permit becomes void and has to be renewed.
We time the application to your real start date rather than filing it the moment drawings are done. (Current as of 2026 — confirm with the borough.)
What gets built in Saint-Laurent
Saint-Laurent holds one of the largest industrial and business-park concentrations on the island — the Côte-de-Liesse and Marcel-Laurin corridors, Technoparc Montréal, and deep office, light-industrial, and flex-space stock. That's tenant-improvement and office-fit-out territory: reconfiguring leased commercial space, not building new.
Most of that interior work doesn't change a building's use or touch its structure, fire separations, or envelope, which keeps it outside the Architects Act and lets us carry it end to end; where a project is subject to the Act, an OAQ-member architect directs that portion of the design from the outset. Our designers are APDIQ members; we build under our own RBQ licence.

Frequently asked
Saint-Laurent — permits & approvals, answered.
How long does a building permit take in Saint-Laurent?
Saint-Laurent was once the slowest borough on the island — averaging about 289 days around 2010 — and had cut that to roughly 42 days by 2017, near the city average of the time. Going from nearly ten months to about six weeks is the real story; it's an improvement, not a ranking. Timelines have shifted since and vary by project, so confirm the current figure with the borough. A complete first submission is the biggest lever you control.
My Saint-Laurent permit is issued — how long before I have to start?
Work must begin within three months of the permit being issued, or the permit becomes void and has to be renewed. Separately, the permit is valid for six months from the start of work. Both clocks matter: a permit pulled too early — before financing, a lease, or long-lead materials are settled — can expire before construction begins, so we time the application to your real start date. (Current as of 2026 — confirm with the borough.)
Do I need an architect for a fit-out in a Saint-Laurent office or flex building?
Often not. Interior modifications that don't change the building's use and don't affect its structure, fire separations, exits, or exterior envelope fall outside Quebec's Architects Act, and a design-build studio can carry them in full — which covers a large share of the office and flex fit-outs common in Saint-Laurent. Where a project is subject to the Act, an OAQ-member architect directs that portion of the design from the outset. We identify which applies at the start.
