What is an Accessory Coach House?
An Accessory Coach House can be defined as a detached secondary suite that is built in the rear yard of a detached single-family residential lot and includes some form of additional parking. Accessory Coach Houses are smaller in size than the principal dwelling and usually compliment the main residence by incorporating similar design features. They can range in square footage and height but normally have no more than two bedrooms. This type of development is also referred to as a backyard cottage, granny flat or laneway housing. Coach House Design Guidelines are often used to address design aspects such as: site planning, building size, and height, side yard setbacks, window placement, allocation of private outdoor space, landscaping and lane frontage treatment.
