Solar Panels

In the City of Waterloo, building permits are required in many cases to install solar panels.

Solar panels that require a permit:

  • If the total area of the solar panel is larger than five square metres (52 square feet) and on a building
  • If they are designed to provide hot water or heating
  • If the weight of the solar panel, snow or wind exceeds the structural capacity of the building's roof or wall

You do not need a permit for ground-mounted solar panels that are not connected to water or heat sources.

You will need to submit a set of drawings, and the following forms to make an application.
