Home additions in Oshawa

Oshawa's 1940s to 1960s bungalows sit on good lots close to downtown, parks and the 401. Many families love the street but outgrow a two- or three-bedroom house. Going up is often the answer: a second storey doubles the living space without giving up the backyard.

A second-storey addition starts below grade. The existing foundation and walls have to carry the new floor, so an engineer reviews them first. Then we plan the new stair, the roof and how the family lives during the work.

Approvals for an Oshawa addition

The City of Oshawa issues building permits and applies its zoning by-law, which sets height, setbacks and lot coverage. If a design needs to go beyond those limits, it may need a minor variance from the City's Committee of Adjustment. Lots near creeks such as the Oshawa Creek can also need a permit from CLOCA.

Living at home during the work

With a second storey, the roof comes off, so most families move out for part of the build. With a rear addition, you can often stay. We talk through the timing during planning so you can arrange where to live.

After receiving a few quotes from different contractors to do a full renovation of our kitchen and dining room, we chose Henley because of how comfortable Nick and his team made us feel right from the first conversation.

From start to finish it took just over three weeks for the team to demolish our ugly, dated, and dark kitchen, and fully rebuild a stunning bright and light new space, designed with style and functionality in mind.

The Henley team was very responsive (shout out to Tom and Michelle), and kept us fully informed throughout the project with the Buildertrend app. They uploaded photos and notes to the app daily, so we always knew where the project was at and how things were progressing. We loved the transparency of this, especially not being at home through the reno.

Thank you Henley Contracting for completely transforming our space.
We are so happy with the final results!

Frequently asked questions

Can't find your answer? Tell us about your project and ask us directly.

Can my Oshawa bungalow take a second storey?

Often, but it depends on the foundation and framing. An engineer reviews them first, and sometimes the foundation needs reinforcing.

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

Usually for part of the work, because the roof comes off. For a rear addition, many families can stay.

Who issues permits for additions in Oshawa?

The City of Oshawa. If the design exceeds a zoning limit, it may also need a minor variance from the Committee of Adjustment.
