Key insights:

The fast-growing District of Squamish (22% increase since 2016) has allowed duplexes in a large portion of the community for many years now. Starting in 2015, the District began to change single family zoning to allow for accessory dwelling units and secondary suites.

As this Small Housing Case Study details, recent years has seen the District of Squamish’s gentle density approaches has expanded into triplexes and cottage clusters, while past and current neighbourhood planning process are expanding missing middle housing options in established areas through infill. Looking forward, the District will consider additional opportunities for increased housing diversity and infill housing, potentially across broader areas through density bonus structures.

Key insights:

The City of Burnaby is steadily growing, with a population increase between 2016 and 2021 of 7%. The City allows for in-law suites and secondary suites in single family dwellings, secondary suites in duplexes, and laneway homes. Demand for secondary suites has been quite strong in Burnaby due to the strong family ties within resident families and other housing factors.

This demand resulted in up to 5,000 unauthorized secondary suites being created to 2014.

As this Small Housing Case Study details, a policy to support authorized secondary suites was adopted in 2014 in order to start keeping track of the units and ensure compliant construction for safety. Now there are close to 1,800 permitted suites and an estimated additional 4,000+ suites unpermitted as tracked by the declaration form.

More recently the City has introduced a program called Housing Choices, to explore and encourage housing options in the city to bridge the gap between single family homes and apartments/condos.

Older central Montreal neighborhoods, developed in the early 20th century, are among Canada’s densest urban areas. This is achieved through the iconic Montreal “plex” design, stacking two or three apartments on narrow lots without sacrificing livability or relying on high-rise buildings.

Key insights:

The older neighbourhoods in central Montreal – developed in the first half of the 20th century – comprise some of the densest urban areas in Canada, something that is achieved without sacrificing livability or frequent recourse to high-rise buildings.

As this Small Housing Case Study outlines, the key to this puzzling success is the iconic Montreal “plex”, i.e., the stacking of two (“duplex”) or three (“triplex”) apartments on narrow (20-25 feet) lots with each apartment having its own front and back door and civic address.

This convivial solution that nicely combines density, livability, affordability, and conservation, iconic to Montreal, flourished in the first half of the 20th century but then fell victim to changing building regulations in the post-war period. A demand for this traditional housing solution eventually led to a relaxation of building regulations and return of the plex as an acceptable housing solution.

This Small Housing Guidance Paper examines the viability of redeveloping houses in single family neighbourhoods with more homes on the same property, presenting recommendations that will assist various actors involved in setting financial and cost recovery policies as it relates to new gentle density development.

Key policy considerations explored include:

Enabling Tenure Options (Rental & Ownership)

Allowing individual ownership, or strata-titling, for each home on a lot will encourage more new units to
be constructed versus requiring that a property have a single owner (i.e. the owner rents out the additional units, or all residents share a single mortgage).

Leveling the cost playing field and reducing risk

Constructing multi-unit buildings is more complex and costly than single family homes; by offering standardized designs and simplifying approval processes it is possible to reduce the uncertainty and costs involved.

Building in affordability

Given the small number of units involved in these projects, it is administratively simpler and more financially viable to take any affordability requirements or financial contribution (if required) and combine them for affordable housing on a larger site.
