How much does second-storey addition cost in Pickering?

With Zigma Group, second-storey addition starts from $260 per sq ft. Prices are in Canadian dollars before HST, as of October 2026, and are confirmed after a site visit. The main factors are floor area being added; reinforcement the existing structure needs; and number of bathrooms and finish level upstairs.

Can a second storey be added to any bungalow?

Most can, but it depends on the foundation and wall structure. An engineer assesses it, and reinforcement is added where needed.

Do I have to move out for a second-storey addition?

Yes, for the main structural phase, because the roof is removed and services are disconnected at times.

Second-Storey Addition in Pickering

Adding a second storey can double the size of a bungalow without using any of the yard. The existing house has to be able to carry it, so the work starts with the structure. In Pickering, most of the housing is 1960s to 1990s subdivisions, with older streets near the lake.

Before you start

What to know.

Can the house carry it?
An engineer checks whether the foundation and walls can support another floor. Some houses need reinforcing first, and that changes the budget.
Permits and zoning
A second storey needs a building permit and must meet height and floor-area limits. Older neighbourhoods often have rules meant to keep new upper floors in scale with the street.
Moving out
The roof comes off, so the house is not liveable during the main structural phase. We plan the sequence to keep that period as short as the work allows.
