Can you tell me about the new Ottawa hardscaping rules?

With Ottawa introducing a new hardscaping contractor licence, there’s been a lot of confusion about what it means for homeowners.

Let’s start with the key point:

Fences, Decks, and Pools Do NOT Require a Hardscaping Licence

If you’re building or hiring work for:

Fences
Decks
Pools

…these do not require a hardscaping contractor licence.

They are governed by separate by-laws and building requirements, such as fence regulations and pool enclosure rules—not the new hardscaping licence system. (more info)

What the Licence Actually Covers

The new licence—required as of March 2026—applies specifically to contractors doing hardscaping work in Ottawa. (more info)

This typically includes:

Driveways and private approaches
Interlock and patios
Walkways and pathways
Retaining walls and similar surface work (City of Ottawa)

In short, it targets ground-level construction that affects grading, drainage, and city infrastructure.

Why the City Introduced It

Ottawa brought in the licence to address ongoing issues with:

Poorly executed driveway and interlock work
Drainage problems affecting neighbouring properties
Damage to City right-of-way areas

The goal is to improve accountability, quality of work, and consumer protection across the industry. (City of Ottawa)

Where the Confusion Comes From

Because this falls under a broader “landscaping” review, many homeowners assume it applies to all outdoor construction.

It doesn’t.

The City clearly separates:

Hardscaping work (licensed)
Other structures like fences, pools, and decks (separately regulated) (more info)

The Bottom Line

This new licence is targeted—not universal.

It does apply to contractors installing surfaces like driveways, patios, and walkways
It does NOT apply to fences, decks, or pools

If your project is above ground and within your yard—like a fence, terrasse, or pool enclosure—you’re outside the scope of this new licensing requirement.
