Infill Housing Program

On This Page

Program Summary

Through the Infill Housing Program, adopted in June 2026, the City is encouraging ground-oriented family friendly housing. This program also responds to Provincial housing legislation by permitting up to six units of infill housing (such as secondary suites, laneway and carriage houses, triplex, quadplex, and multiplex forms of housing) on single detached dwelling and duplex properties across most of the city. These changes streamline the application process by removing the need for a site-specific rezoning application. Owners may also choose to stay in their existing home, or choose to renovate or rebuild their home, rather than build any infill housing.

Right now, the City is not making changes to housing regulations in Queensborough because more research is needed on infrastructure like water and sewer systems to see if the area can support more housing. The City will consult with residents before any changes in Queensborough are finalized.  

Developing Infill Housing

If you own a property that is zoned RGO-A or RGO-B, you can apply for a Development Permit and Building Permit without a rezoning application. Read the Infill Housing Guide to learn more about the application process.

Properties with heritage assets may instead apply for a Heritage Revitalization Agreement, which allows the City to supersede zoning regulations to provide non-financial incentives which would make it viable to conserve the property.

Revised regulations for small or compact lot subdivision were not included in the Infill Housing Program, as single detached dwellings are already well-represented in the city’s current housing stock. At this time staff is not recommending support of small or compact lot rezoning applications to Council.

Infrastructure Considerations

New infill housing will increase housing choice in our established neighborhoods. However, this development comes with some unique challenges. One such challenge is the infrastructure and servicing needed to support this additional growth. The current infrastructure was designed for the previous zoning entitlements of up to three units (in the form of a single detached dwelling, secondary suite and laneway house). In many cases, infrastructure upgrades will be required to facilitate the additional units enabled by zoning, as envisioned by the provincial housing legislation. The City will continue replacing and upgrading infrastructure over time as part of ongoing civil work. In the meantime, projects developing more than three units in advance of the City’s civil work will have to undertake all necessary infrastructure upgrades at their cost. This is anticipated to be cost prohibitive for some applications given the small scale of development. This highlights the need for senior government funding support for the City to be able to deliver the infrastructure needed to enable growth, in support of the community’s housing needs. The City continues to advocate to the Province and the Federal Government for funding to support future urban growth.
