Small-Scale Multi-Unit Home (SSMUH / Multiplex) Update June 2024

Updated: Jun 30

In the few weeks before the Province of BC's June 30 deadline to amend zoning bylaws, city governments have provided updates and usually proposed amendments that spell out exactly what you will be permitted to build on a single-family property starting this July.

In this article - which I will be updating and expanding regularly as additional municipalities report back - I summarize the main points from Council Minutes, city staff reports, and city publications. If you don't want to hunt for or wade through the information from your city, this summary gives a quick idea of what's coming (or not) down the pike in July.

Most cities appear to have followed through with the provincial directive as intended, but several municipalities have responded otherwise and for different reasons. Regardless, the information is strewn about in various forms and levels of completion largely due to the huge impact that the provincial mandate has on city rules, so you may not know what the situation is where you live. More importantly, you may be banking on building in your city what is allowed elsewhere when it might not be.

Abbreviations you might need to know:

ADU: Accessory Dwelling Unit - a smaller building typically behind the main house, which contains typically one independent dwelling unit

FSR / FAR: Floor Space Ratio / Floor Area Ratio - a ratio of the total floor area of the building divided by the area of the property.

SSMUH: Small-scale multi-unit home - the new term introduced by the province for a development consisting of three or more dwelling units

TOD Area: Transit-Oriented Development Area - properties within 800m of a rapid transit station (e.g. Skytrain) or 400m of a bus exchange

Are you looking for what the rules are in your city but don't see them in the list above? Email me with a request; I'll dig up what's available and add your city to the list

My experience spans over two decades in the architectural industry in Western Canada serving clients who were individuals, private developers, and public governmental departments with diverse priorities and needs. I'm a member of Passive House Canada and International Passive House Association, so I understand not only the need for detailed design but also the need for a design that intrinsically keeps the cost of construction down.

My SAPPHR Strategy™ is my process to ensure all requirements are identified at the outset of a project and that the design then meets the resulting objectives. Wandering through design, assuming that the final building will fulfill your objectives and hoping that the cost will be manageable is a dangerous gamble.

The very first step in my SAPPHR Strategy™ is a pre-design study which I call the RED Report™. RED stands for Real Estate Development and shows you the options available to you; it's a quick and inexpensive report that allows you to compare options and determine which best suits your needs.

You can download a free sample of the report which includes renovations, new houses, and laneway homes; but I've just developed a brand-new version of the RED Report™ specifically for the SSMUH / multiplex / houseplex development. In this new report, you'll find out:

  • how many dwelling units you are permitted to build

  • how large the dwelling units are allowed to be

  • how much floor area you're allowed to build

  • what building configurations are permitted

  • the maximum number of storeys and maximum building height allowed

  • the maximum site coverage permitted for your development, and

  • how many parking stalls are required
