Additional Residential Unit

An Additional Residential Unit is a type of dwelling unit providing an accessory to a principal dwelling on the same property. These units can be either connected or detached to the principal home. Examples of commonly used ARU's include basement apartments, granny flats, coach homes, in-law suites, tiny homes, garage apartments and modified shipping container dwellings. 

Who is eligible for an Additional Residential Unit? 

The requirements for an Additional Residential Unit are dependent on a few factors, and will differ based on the servicing of your property (if you're on well / septic or have municipal water and sanitary services), and if you're proposing an attached or detached ARU (for example a basement apartment as opposed to converting an outbuilding to a dwelling unit).
