Val-des-Monts fence by-laws

Val-des-Monts is the most permissive municipality in the region on rear yard height and the strictest on corner lots. The two numbers to remember are 2.5 metres and 8 metres.

Verified 3 August 2026 with the City of Gatineau and the Government of Quebec.

The short answer

1.5 m in the front margin, 2.5 m in side and rear margins. That 2.5 m is the most generous residential height we have measured in the Outaouais: Cantley and Gatineau stop at 2 m.

The visibility triangle, however, is the largest in the region at 8 m a side, and nothing taller than 75 cm may sit inside it.

The same maximums apply to a low wall.

The heights, and what they are measured from

WhereFenceLow wall
Front margin1.5 m1.5 m
Side margin2.5 m2.5 m
Rear margin2.5 m2.5 m

Height is measured from the average ground level where the fence is built, erected or planted.

One detail that matters and that few people anticipate: those three limits are tied to the front, side and rear margins, and the depth of those margins is set zone by zone in the specifications grid. To know where your front margin ends you need your zone's grid. We check it during the visit.

The visibility triangle: 8 m, the largest in the region

On a lot at the intersection of two streets, the triangle must stay clear of any obstacle taller than 75 cm, measured from street level. Each side is at least 8 m from the point where the streets intersect.

No parking space may sit inside it. A structure on a single post, or not fixed to the ground, may encroach if it is 2.7 m or more above ground.

There is a rare exception: the rule does not apply where, after inspection, a hedge inside the triangle and taller than 75 cm is found not to obstruct traffic safety.

Prohibited materials

The list applies to fences, low walls and retaining walls alike:

  • Chicken wire, except for agricultural uses.
  • Barbed wire, except the Industry and Agricultural groups.
  • Exposed particle board, chipboard or plywood.
  • Sheet metal, sheet-metal or steel panels and similar materials.
  • Canvas, fabric, textiles and similar.
  • Any flexible material (plastic, cardboard, paper) lacking the rigidity to ensure safety or prevent intrusion.
  • Any other material not specifically intended for building fences.

One more siting rule: fences and hedges must sit at least 1.5 m from any public utility equipment.

Pools, where Val-des-Monts is unusually precise

A pool enclosure must:

  • block the passage of a 10 cm sphere;
  • if chain link, have mesh no wider than 30 mm (slats may widen it, without letting more than 30 mm through);
  • be at least 1.2 m high;
  • carry no fixing, projection or open part that would help climbing.

A hedge or shrubs cannot serve as a pool enclosure. The gate must have a passive safety device that closes and locks it automatically, placed inside in the upper part, or outside at least 1.5 m above ground.

An above-ground pool with a wall at least 1.2 m everywhere, or a demountable pool of 1.4 m or more, needs no enclosure if access is controlled. The provincial rule applies on top: see our Quebec pool fence law guide and the 30 September 2027 deadline.

What we will not tell you here, and why

Two questions come up often and we will not publish an answer until it is confirmed, because a wrong answer costs more than no answer.

  • Does a fence need a permit or certificate in Val-des-Monts? The word for fence appears in neither of the two tables in the permits and certificates by-law that list the works requiring one. Yet the fee schedule in that same by-law carries a line reading « Piscine et clôture, 55 $ ». The two contradict each other. To be confirmed directly with the Municipality.
  • How far from the lot line? The by-law contradicts itself here too. We will publish neither 0 m nor 1 m until it is settled.

We ask both questions for you before starting a project in Val-des-Monts.

Sources, and the date we checked them

Verified on 18 September 2026 against the Municipality of Val-des-Monts' own documents.

  • Zoning By-law no. 939-24, adopted 18 February 2025 (resolution 25-02-058). Fences are at articles 81 to 84 and the visibility triangle at article 80.
  • By-law on permits and certificates no. 942-24.

We do not publish an in-force date, because the by-law itself gives none and we could not confirm one against a live official document. Adoption on 18 February 2025 is verified. A by-law can be amended: confirm with the Municipality before ordering, or ask us to do it.

Frequently asked questions

Val-des-Monts fence by-laws

How tall can a fence be in Val-des-Monts?
1.5 m in the front margin, and 2.5 m in side and rear margins. The same maximums apply to a low wall. That 2.5 m is the most generous residential height we have measured in the Outaouais.
What is the visibility triangle in Val-des-Monts?
Each side is at least 8 metres from the point where the two streets intersect, and nothing taller than 75 cm may sit inside it, measured from street level. It is the largest triangle in the region. No parking space may sit inside it either.
Do I need a permit for a fence in Val-des-Monts?
We are not publishing an answer, because the municipal documents contradict each other. The word for fence appears in neither table listing works subject to a permit or certificate, yet the fee schedule in that same by-law carries a line reading Piscine et clôture, 55 $. It is a question for the Municipality directly, and we ask it for you.
How is the height measured?
From the average ground level where the fence or low wall is built, erected or planted. Note that the three limits are tied to the front, side and rear margins, and the depth of those margins is set zone by zone in the specifications grid.
Which materials are prohibited in Val-des-Monts?
Chicken wire except for agricultural uses, barbed wire except the Industry and Agricultural groups, exposed particle board or plywood, sheet metal and steel panels, canvas and textiles, any flexible material lacking rigidity, and more broadly any material not specifically intended for building fences.
What are the pool enclosure rules in Val-des-Monts?
The enclosure must block a 10 cm sphere, be at least 1.2 m high, carry nothing that helps climbing, and if it is chain link have mesh no wider than 30 mm. A hedge cannot serve as an enclosure. The gate must close and latch automatically.
Does a hedge count inside the visibility triangle?
In principle yes, but Val-des-Monts provides a rare exception: if, after inspection, a hedge inside the triangle and taller than 75 cm is found not to obstruct traffic safety, the rule does not apply to it.
Do you serve Val-des-Monts?
Yes, and we are already well established there. We have installed across the Outaouais since 2018. During the visit we confirm the height for your zone, the visibility triangle and the permitted materials.

Kevin & his team were very easy to work with and I'm very happy with the result of my new fence. I changed a few things to the original plan and there was no trouble or hassle in doing so. I'm already planning to hire them for another project!
