Elgin Street and Hawthorne Avenue Functional Design Study

The City of Ottawa "is undertaking the functional design and transportation study for the continuous corridor of Elgin Street between Laurier Avenue and Queen Elizabeth Driveway, and Hawthorne Avenue from the Pretoria Bridge to Main Street." For more details about the study, please visit the City of Ottawa website.

Secondary Dwelling units in Accessory Structures Zoning Study

The City of Ottawa "is undertaking a zoning study that will determine the appropriate zones and standards to permit secondary dwelling units within accessory structures, in residential neighbourhoods. These types of dwelling units are essentially a small apartment or suite in the backyard of a home or along a laneway" (often referred to as "coach houses"). For more details about the study and access to all the documents and reports, please visit the City of Ottawa website.

The R4 (Residential Fourth Density) family of zones is the city's most intensive low-rise residential zone. It is the only family of residential zones designed to permit low-rise apartment buildings with four or more dwelling units. R4 zoning covers much of Ottawa's old established low-rise neighbourhoods in the inner urban area, including Centretown, Sandy Hill, Vanier, Overbrook, Hintonburg and Westboro. Smaller pockets of R4 zoning can be found throughout the city.

UPDATE: The City of Ottawa's Planning Committee approved the report at their meeting on October 11, 2016. Minutes from the meeting are available on the
City of Ottawa website.

City of Ottawa R4 Zoning Review

The City of Ottawa will be conducting the R4 Zoning Review "to address those issues most commonly found in inner-urban, low-rise multi-unit development. While the focus will be on the R4-zoned areas, the review may also touch on aspects of the zoning by-law applicable to other inner urban zones, such as the R3 zones in the Glebe and Old Ottawa East. Although the focus is on the inner-urban wards (i.e. Wards 12 through 17) the review may to a lesser extent have implications city-wide, particularly in areas with a significant amount of R4 multiple-unit zoning. Of particular interest is the tendency towards oversized dwelling units (with as many as six, eight or even twelve bedrooms) being developed in duplexes, triplexes and low-rise apartment dwellings. The review will look at such zoning matters as limits on permitted bedroom counts, definition of a "dwelling unit" versus a "rooming house," and permitted unit counts in R4 zones."

Key considerations for the R4 zoning review are:

  • Ensuring that new low-rise apartment buildings permitted in the R4 zones are compatible and fit with their neighbourhoods in both form and function
  • Ensuring that the R4 zones can continue to accommodate the growing number of people who want to live in the inner-urban, low-rise neighbourhoods in a way that balances the needs of new residents with those of existing residents and maintain a sense of stability
  • Allowing the R4 zones to accommodate the need for affordable housing while protecting the character of the R4 urban neighbourhoods

    Community Design Plan (CDP)

    The approval of the CDP is the culmination of a long, long process. This could not have been achieved without the support and diligence of many community members, especially those who served on the Public Advisory Committee (PAC), and the institutional landowners.

    The CDP is meant to provide a broad and integrated twenty year vision and guidance for growth in the community. Although focused on Main Street, a key component of the CDP is the potential sale and intensification of the lands currently owned by the Oblate Fathers and the Sisters of the Sacred Heart. In particular, the properties owned by the Oblate Fathers have considerable redevelopment potential and will likely be sold for redevelopment over the next decade. The OECA remains committed to working closely with key stakeholders to ensure that community consultation is represented throughout the redevelopment process. In 2010, members of the CDP Public Advisory Committee (PAC) began actively meeting with stakeholders to prepare principles to guide planning and design of the lands. That culminated in the March 10, 2011, public open house held at Saint Paul University where a demonstration plan, illustrating one possible development scenario for the lands, was presented to the community. For more details, view the open house presentation.

    The CDP was presented at the city's planning committee meeting on June 28, 2011. To view the official minutes from the meeting, please click here. The CDP was given final approval, with amendments, at the city council meeting on August 25, 2011. To view the final report as approved at council please click here (listed as “Planning Committee Report 12A”).

    Development Applications

    Development refers to change of land use or the construction or addition to a building(s) or the creation of a parcel of land.

    Applications for site plan control approval, minor variance(s)/consent, and zoning by-law amendment are mailed to the OECA and are reviewed by the OECA's planning committee. Some applications are also mailed to neighbours within a 60 metre radius of the subject property. OECA members are encouraged to participate in the development review process.

    • Zoning by-law Amendment 2012-147 - May 2012 - provides regulations for the control of low-rise residential infill development in mature neighbourhoods. Please note: These infill regulations were appealed to the OMB. You can view the March 8, 2013, OMB decision here. The OMB decision rules in favour of most of the regulations, including front yard setback averaging; front yard projections averaging; and the direction and location of parking, balconies, driveways, walkways and landscaping. The decision, however, requires the city to reconsider certain regulations, including the parts applying to new construction only and not renovations; narrow lots not having garages doors facing frontwards; the width of a garage door or carport not exceeding 50% of the front façade; garage or carport being set back further than the main façade; and the amount of glazing in the ground floor front wall. Update Aug. 2013: Wherein the OMB decision allowed the City five months to redraft the regulations for further OMB deliberation, this timeline was been extended until December 31, 2013. Update Nov. 2013: The December 31st timeline has been extended until March 31, 2014.
