Item 6 — Adding Contextual Single Detached Dwelling as a Permitted Use

Understanding what was added, why it happened, and what both sides say about it

What Happened

Bylaw 21P2024 added a new housing type called a Contextual Single Detached Dwelling to the list of permitted uses in the R-CG district. This was done by inserting subsection 526(b.1) into the Land Use Bylaw.

As a permitted use a Contextual Single Detached Dwelling can be automatically approved without a public hearing or discretionary review, provided it meets the written rules in the bylaw.

What Is a Contextual Single Detached Dwelling?

The Basic Definition

A Contextual Single Detached Dwelling is a single family home that is designed with specific reference to the physical context of the properties around it. Rather than being built purely to abstract minimums and maximums in the bylaw it is required to respond to what already exists on the street.

What Makes It Contextual

In practical terms the building's design must respond to:

• Setbacks: How far the building sits from the property lines must relate to the setbacks of neighbouring buildings

• Height: The height of the building must relate to the height of neighbouring buildings

• Massing: The overall scale and bulk of the building must be designed with reference to adjacent development

How It Differs From a Regular Single Detached Dwelling

A regular Single Detached Dwelling in R-CG is a discretionary use:

• Requires a decision by the Development Authority

• Neighbours are notified and can submit written comments

• The Development Authority can approve, approve with conditions, or refuse

A Contextual Single Detached Dwelling is a permitted use:

• Automatically approved if it meets the bylaw rules

• No Development Authority decision required

• Neighbours are not notified

• The only grounds for refusal are non-compliance with written rules

Why Did the City Add This?

Encouraging Sensitive Infill Development

By making contextual single detached dwellings a permitted use the City created an incentive for developers and homeowners to build new single family homes that respond to their surroundings. The faster and cheaper permitted use pathway rewards designs that fit their context.

Providing a Clear Pathway for Single Family Development

With the broader shift of R-CG toward higher density housing types adding a clear permitted use pathway for contextual single family homes signals that single detached development remains a valid and supported option in established neighbourhoods.

Rewarding Good Design

The contextual requirements mean that the permitted use pathway is only available to designs that genuinely respond to their neighbourhood context. Designs that ignore that context would need to go through the discretionary process instead. This creates a design incentive similar in principle to the one that existed for rowhouses under the old 347.3 standards.

Internal Consistency

Contextual Semi-detached Dwellings were already a permitted use in R-CG before Bylaw 21P2024. Adding Contextual Single Detached Dwellings to the permitted use list creates consistency between the two similar housing types.

What Are the Concerns About This Change?

It Does Not Address the Core Issue

Critics argue that adding a contextual single detached dwelling as a permitted use is largely symbolic in the context of the broader changes made by Bylaw 21P2024:

• The fundamental concern of many residents is not about single family homes

• Single family homes were already possible under the old zoning

• The concern is about higher density development

• This change does not limit the ability of developers to build rowhouses or townhouses

• Its practical impact on the overall density trajectory of established neighbourhoods is limited

No Neighbour Notification

Because contextual single detached dwellings are permitted uses neighbours are not notified when an application is made:

• While a new single family home is generally less impactful than a rowhouse the absence of any notification process means neighbours have no opportunity to raise concerns

• A contextual single detached dwelling that technically meets the bylaw rules but still has significant impacts on neighbouring properties can be approved without any neighbourhood input

The Contextual Requirements May Be Applied Loosely

The requirement that a building respond to its context depends on how contextual rules are written and interpreted:

• What qualifies as sufficiently contextual is a matter of judgment

• Critics argue that contextual requirements can be applied loosely in practice

• There is no guarantee that what is approved as contextual will genuinely reflect the character of the surrounding street

• The Development Authority has discretion in how it interprets contextual compliance

A Concession That May Obscure Larger Changes

Some observers have suggested that adding a contextual single detached dwelling as a permitted use functions partly as a visible concession to residents concerned about neighbourhood character:

• It signals support for single family development in the overall package of changes

• It softens the perception of the bylaw without substantively limiting its density-enabling provisions

• Critics argue the gesture is meaningful in appearance but limited in practical effect

What Does This Mean in Practical Terms?

For a Homeowner Building or Replacing a Single Family Home

• If the design meets the contextual requirements it can be approved as a permitted use

• The process is faster and cheaper than a discretionary application

• Neighbours are not notified and cannot comment before a decision is made

• The building must respond to the setbacks, height, and massing of neighbouring properties

For a Homeowner Whose Neighbour Is Building a New Single Family Home

• You will not receive notification of the application

• The Development Authority will approve it automatically if it meets the bylaw rules

• You will have no formal opportunity to comment before a decision is made

• If you have concerns about the design your options after approval are limited

For Residents Concerned About Higher Density Development

• This change does not limit the ability of developers to build rowhouses or townhouses in R-CG

• It creates a faster pathway for single family development but does not restrict other housing types

• The overall density trajectory of established neighbourhoods is not meaningfully affected by this addition

For Developers

• A faster and cheaper approval pathway is available for single family homes that meet contextual requirements

• Designs that do not meet contextual requirements still have a pathway through the discretionary process

• The incentive structure rewards contextually appropriate single family design with a streamlined approval

Key Facts

• What was added: Contextual Single Detached Dwelling as a permitted use in the R-CG district

• Where it was inserted: Subsection 526(b.1) of Land Use Bylaw 1P2007

• What makes it contextual: The design must respond to the setbacks, height, and massing of neighbouring buildings

• Use classification: Permitted use — automatically approved if bylaw rules are met

• How it differs from a regular Single Detached Dwelling: A regular Single Detached Dwelling in R-CG is a discretionary use requiring a Development Authority decision and neighbour notification

• The City's argument for adding it: To encourage sensitive infill, provide a clear single family pathway, reward contextually appropriate design, and create internal consistency with Contextual Semi-detached Dwellings

• Primary concern among critics: The change is largely symbolic and does not address the core concerns about higher density development in established neighbourhoods

• Who benefits most: Homeowners and developers building new single family homes who want a faster and cheaper approval process
