What is a Secondary Suite?

A secondary suite is a self-contained residential unit with a private kitchen, bathroom facility and sleeping area and living area within a dwelling or within a structure that is accessory to a dwelling with access gained either through a separate entrance or common area.

Why Secondary Suites?

The City of Peterborough is permitting the creation of secondary suites to achieve the following objectives:

  • To provide housing for a variety of users including aging family members, adult children, caregivers etc.
  • To increase the supply of rental housing and improve rental affordability
  • To alleviate the cost of homeownership
  • To make efficient use of infrastructure, housing stock, land and resources
  • To facilitate residential intensification, mitigate climate change, and reduce greenhouse gas emissions
