Règlement 152-2023 lets the municipality evaluate how a project looks — not just whether it's allowed — in the heritage core, along the Route 201 Sud corridor, on rue Isabelle, and anywhere a backyard accessory dwelling is built. Skipping the process is an offence, with fines that run as high as $2,000 a day.
PIIA stands for Plan d'implantation et d'intégration architecturale — a planning tool authorized under Quebec's Loi sur l'aménagement et l'urbanisme that lets municipalities go beyond pass/fail zoning rules to evaluate the quality and appearance of a project. Before a permit or certificate is issued in a PIIA zone, the file goes through a design review most of the rest of town never sees: does it fit the character of the street, are the materials and colours appropriate, does it harmonize with the neighbours.
Ormstown adopted its first PIIA regulation in 2011. The current version, Règlement 152-2023, took effect as part of a broader regulatory overhaul completed in March 2024.
Four sectors are covered, from largest to smallest. The heritage core (noyau architectural) is the biggest — downtown, mixed-use areas, several park zones, and a number of residential streets in the older part of the village: zones C-5, MXT-1 to MXT-3, P-5 to P-9, P-11, R-13, R-15 to R-17, and R-29 to R-32.
A second sector runs along the Route 201 Sud corridor, covering commercial, industrial, and mixed zones C-7 through C-10 and I-1 — though signage rules don't apply in zone C-7. A third covers Zone R-37 on rue Isabelle, but only for new construction and additions to a main building.
The one that catches most people off guard: the PIIA applies territory-wide to any detached accessory dwelling unit (UHAD) — a secondary suite, a converted garage, a backyard cottage — no matter where the lot sits in Ormstown.
Not sure which zone you're in? The zoning map for the urban perimeter is publicly available on ormstown.ca.
In the heritage core, any of the following requires PIIA approval before a permit or certificate can be issued:
Along Route 201 Sud, all of the above applies plus any new or modified front-yard parking (signage rules are the exception in zone C-7). On rue Isabelle's Zone R-37, only new construction and additions trigger a review. For an accessory dwelling unit anywhere in town, both the initial build and later exterior renovations — cladding, roofing, openings, roof form — require approval.
It isn't a rubber stamp. A PIIA application moves through five steps:
Any change to the plans after council approval means starting over with a full new application. In practice, the time it adds to a project depends on where an application lands relative to the CCU's meeting schedule — budgeting extra weeks ahead of an exterior renovation is worth it.
Unlike zoning, which is pass/fail, PIIA criteria are qualitative. In the heritage core, reviewers ask whether a new building's scale matches its neighbours, whether materials, colours, and roof form are harmonized with the area, and whether additions sit toward the rear rather than the front. For renovations specifically, the regulation calls for subdued, harmonized colours, accent colours used sparingly, and — where a previous owner already altered a building's character — an effort to restore it. Signage must read as an architectural element integrated into the building, not bolted on, with discreet, ground-mounted lighting.
Along Route 201 Sud, the emphasis is on the commercial streetscape: facades parallel to the road, minimal setbacks, and front parking visually screened with vegetation, fencing, or landscaping. For an accessory dwelling unit anywhere in Ormstown, the bar is architectural consistency with the main building — materials, roof pitch, colours — sited preferably in the rear yard, preserving mature trees and green space where possible.
Proceeding with work that required PIIA approval without getting it is an offence under municipal law. Fines for a first offence start at $500–$1,000 per day for individuals and $600–$2,000 per day for corporations. Repeat offences climb to $800–$2,000 per day for individuals and $800–$4,000 per day for corporations. Every day the violation continues counts as a separate offence, and the municipality can also pursue civil or penal remedies under Articles 227–233 of the Loi sur l'aménagement et l'urbanisme.
Before starting any exterior work on an Ormstown property — especially in the older part of the village — call the planning department first. Staff can confirm whether the property sits in a PIIA zone, whether the specific project triggers a review, and what documents to prepare.
