Secondary Dwelling units in Accessory Structures Zoning Study

Overview and Timelines

Project consultation activities are planned as part of the study process until late summer/early fall 2016.

The City 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.

The City already permits a secondary dwelling in detached, linked-detached, semi-detached or townhouse dwelling in any zone where that dwelling type is listed as a permitted use. The current definition of a secondary dwelling unit is:

This image shows the a graphic sketch of three homes on three separate lots, each with a detached secondary dwelling unit in the rear yard.

a separate dwelling unit subsidiary to and located in the same building as an associated principal dwelling unit; and its creation does not result in the creation of a semi-detached dwelling, duplex dwelling, three-unit dwelling or converted dwelling.

What is being proposed?

This study proposes to amend the Zoning By-law to also permit secondary dwelling units within accessory structures in residential zones.  The study will consider the possible zoning provisions and standards at which any new secondary dwelling unit within an accessory structure must meet. The study will also consider further limiting the types of dwelling units that may have a secondary dwelling unit within an accessory structure.

Why now?

The province of Ontario, through the Strong Communities through Affordable Housing Act, 2011 requires municipalities to authorize second units in detached, semi–detached and row houses, as well as in ancillary structures. The City of Ottawa currently permits Secondary Dwelling Units (SDU’s) within primary residential buildings in all residential zones. However our policy structure and current zoning provisions do not allow for SDU’s in accessory structures as-of-right, for example in detached garages. The Planning and Growth Management Department has received numerous public inquiries requesting policy and zoning support for SDU’s in accessory structures. Many Canadian and American municipalities have put in place policy and zoning mechanisms to allow SDU’s in accessory structures. SDU’s support intensification goals by providing opportunities to introduce more dwellings in established neighbourhoods and broaden affordable housing options.

The Study Area

The Study area is city wide, looking at allowing these types of units on urban, suburban and rural properties.  

Discussion Paper

The Discussion Paper is intended to review the considerations surrounding permitting secondary dwelling units within accessory structures. This form of residential intensification will be termed Coach Houses in the City of Ottawa with intent to depict a small apartment in a backyard of a home or above a detached garage.

Online Questionnaire Results

The questionnaire solicited public feedback on specific issues with allowing Coach Houses. The feedback generated from the questionnaire will help to determine the applicable zoning regulations that are considered for the next phase of the study. The questionnaire closed on November 6, 2015 and during that period, 436 questionnaires were received.

Guiding Principles and Draft Recommendations Paper

The Guiding Principles and Draft Recommendation Paper provides the basic principles that were used to inform the directions of the draft Zoning By-law performance standards to allow Coach Houses in Ottawa. The Guiding Principles were formed from the public feedback from the first consultation and the direction of the provincial legislation.

The Guiding Principles and Draft Recommendations paper invited general comments from the public. The comments were welcomed on any topic to help further shape the policy and Zoning By-law provisions for how to allow Coach Houses in Ottawa. The comment period commenced with the preparation of the paper on January 26, 2016 and closed February 29, 2016. During this time 130 submissions were received providing 354 comments over a variety of topics.
