Will the Residential Infill Project make houses larger?

No. The proposals impose new, stricter limits on house size beyond what is presently allowed in R2.5, R5 and R7 zones. Houses would be limited to 2-1/2 stories. Minimum front setbacks would be increased in the R5 zone, unless a house on either side sits closer to the street. Methods for measuring height would be improved to minimize the ability to circumvent maximum height restrictions.

House bulk will be controlled through the introduction of a floor area ratio (FAR) limit, a common technique used to control building bulk in Portland’s non-residential zones and in residential areas in other U.S. cities. The FAR limit would be tied to the size of a lot, better ensuring that a house’s mass is proportional to its lot size. Moreover, the FAR limit represents a significant reduction in the maximum size a house could be from what is allowed today.
