Build a coach house

A coach house is a detached compact home, which is a type of infill housing usually built in the rear yard of a single-family residential lot.

Sometimes called a laneway house or carriage home, a coach house can provide you with additional rental income, while increasing the diversity of rental housing choices in single-family neighbourhoods.

A coach house can't be sold separately from the main house or placed under strata title.

Can you build a coach house on your property?

To be eligible to build a coach house, your lot and proposal must meet these general requirements:

How to apply to build a coach house

If your lot and proposal meet the general requirements, you can apply to build a coach house. The application process varies depending on whether or not your lot has access from a lane or local street, and in some cases, the size of coach house you want to build.

Lots with local street or lane access

If you have a corner lot that is at least 15m wide and 36.5m deep and on a local street, or a lot that is at least 15m wide and has open lane access, the process you use to apply depends on the height of the coach house you want to build.


Lots without local street or lane access

Lots that qualify for coach housesIf you have one of these lots, you will first apply for a development variance permit for access, and then a building permit:

  • Corner lot that is at least 15m wide and 36.5m deep and on a non-local street
  • Lot with double frontage (street at both ends) at least 15m wide
  • Lot with no lane access, but at least 929 sq m 

Not all single family home sites are suitable for coach house development. Be sure to confirm with us that your property qualifies before you proceed with your application.

Watch for potential changes

In spring 2022, we asked for your input and feedback on potential changes to our coach house regulations.

We are working on multiple regulatory changes to increase options in single family neighbourhoods, including proposed changes to the coach house regulations.

Increasing housing choice and diversity

Coach houses help increase the diversity of housing choices in single-family neighbourhoods.

A healthy and diverse range of housing options will improve affordability throughout the entire housing continuum, and will lead to a more vibrant, inclusive, diverse, and well functioning community.
