Ottawa is changing the way neighbourhoods are zoned. The old system (R1, R2, etc.) is being replaced with new rules (N1, N2, etc.) to make housing easier to build and more affordable.
What’s New?
Simpler zones: R1/R2 are now N1/N2 with clearer rules.
More housing options: Triplexes and small multi-units allowed in more areas.
Lower building heights in some areas: 8.5–11m, keeping neighbourhoods low-rise.
Parking rules relaxed: Fewer mandatory spots needed.
Easier approvals: Fewer variances required.
Example: R1/R2 → N1/N2
Before (R1/R2): Mostly single or semi-detached homes, strict parking and density rules.
Now (N1/N2): Single homes, semis, triplexes, and small multi-units allowed as-of-right. More flexible density and reduced parking requirements.
Quick Comparison
Concerns & Criticisms
Neighbourhood changes: More multi-units may increase traffic, noise, and density in areas used to single-family homes.
Parking pressure: With reduced requirements, residents may struggle to find on-street parking.
Infrastructure strain: Added density could stress schools, transit, water, and sewers if upgrades don’t keep pace.
Bottom Line
Ottawa’s new zoning law is designed to make it easier to build different types of housing, keep neighbourhoods livable, and support future growth. But it also raises concerns about parking, infrastructure, and how neighbourhoods will change.
