How Much Does It Cost to Build a Deck in Ottawa in 2026?
If you’re planning to build a deck this year, one of the first questions you’re likely asking is:
“How much does a deck cost in Ottawa?”
The answer depends on several factors, including size, materials, permits, and structural requirements. In 2026, most professionally built decks in Ottawa fall into the following ranges.
Average Deck Cost in Ottawa
Typical professionally built decks in Ottawa cost between:
$22,000 – $45,000+
Here is a general breakdown:
| Deck Type | Typical Price Range |
|---|---|
| Pressure treated wood | $18,000 – $28,000 |

| Composite deck | $25,000 – $40,000 |
| PVC deck | $28,000 – $50,000+ |
Low-maintenance composite and PVC decks are becoming the most popular option because they require very little maintenance and last significantly longer than wood.
What Factors Affect Deck Pricing?
1. Deck Size
The larger the deck, the more framing, decking, and labour is required.
Most Ottawa backyard decks range from 200–400 square feet.
2. Height of the Deck
Higher decks require:
Larger structural beams
Additional footings
Railings
More labour
A raised deck can cost 20–40% more than a ground-level deck.
3. Permit and Engineering Requirements
In Ottawa, most decks require:
City permits
Engineered footing specifications
Inspections
Working with a builder who handles this process can save homeowners significant time and stress.
4. Material Selection
The biggest pricing difference usually comes down to the decking material.
PVC and composite products cost more upfront but eliminate ongoing costs like:

sanding
sealing
replacing warped boards
