Urban Design Guidelines for Low-rise Infill Housing
Since these Guidelines were created in 2012, Council has adopted two sets of infill zoning regulations affecting one- to four-storey residential dwellings. Zoning By-law 2012-147 created the Mature Neighbourhoods Overlay that affects dwellings within the inner urban neighbourhoods (Wards 14, 15 and parts of 12, 13 and 17). The Overlay contains regulations intended to recognize the established look along a street. These include regulations on the use of lands in the front and corner side yards including amount of landscaping, rear lane access, driveway widths and on-site parking, as well as the orientation of the main door, and the minimum amount of habitable floor area required on the first floor, closest to the existing average grade. Flag lot, corner lot and long semi-detached dwelling developments are introduced and regulated.
Infill II By-law 2015-228 creates the Alternative Provisions for Urban Areas in the R1-R4 Zones that affect inner and outer urban wards (Wards 7-18). These regulations affect building height, rear and side yard setbacks, projections above the height limit, including rooftop terraces, projections into required yards, including balconies, patios, etc. The purpose of these rules is to limit building height and mass, privacy issues, sun obstruction, loss of permeable surfaces and soft landscaping to allow for new dwellings and additions that fit in with the established character of the neighbourhood.
When reading these Guidelines, please note that the zoning regulations noted above take precedence over these. The Guidelines will be updated accordingly, to reflect the intent of these Infill zoning regulations.

Below is a series of design guidelines for infill housing to help fulfill some of the design strategies for Ottawa as outlined in the Official Plan. It is intended as a basic framework for the physical layout, massing, functioning and relationships of infill buildings to their neighbours.
