Orangeville’s adopted 2025 ARU zoning amendment

What is permitted

Bylaw 2025-011, passed February 10, 2025, amended Zoning Bylaw 22-90 to permit additional residential units in detached, semi-detached and townhouse properties, within the main dwelling and/or an accessory building. The number and arrangement of units remain subject to the amendment’s detailed rules.

Parking and access

The Town’s online zoning general provisions list one parking space per additional residential unit. Confirm driveway, pedestrian-access, bedroom, detached-building height and setback rules before designing the unit.

What to check before applying

Confirm the existing dwelling type, zoning, available parking and detached-building location against Bylaw 2025-011. A zoning permission is not a building permit.

Next planning steps

Confirm local zoning before you estimate project costs.

This guide explains the municipal process, not whether your specific property is approved. The next two steps are budgeting and contractor scoping; neither replaces municipal approval.

Planning sequence: rules → budget → written scope / contractor. Cost models and contractor matching do not determine whether the municipality will approve the work.

Municipal zoning: verified research register

Governing municipal bylaw: Zoning Bylaw 22-90 §5.29; Amendment 2025-011

Suite and ADU rules: Eligible lots permit principal dwelling plus two ARUs. Maximum two bedrooms per ARU; detached height generally 4.3 m, or 6.1 m above garage; one additional parking space per ARU.

Property-level determination: These figures are conditional on the current zoning district, lot servicing, and any overlays. Provincial housing legislation is background; the adopted local bylaw controls. Unverified requirements: Requires manual municipal check.

How this guide was verified

Guide verification: Official-source research summary. This guide provides linked municipal research; a complete enacted-bylaw, zoning-map and amendment cross-check has not been documented for this municipality.

Property confidence: Not assessed. City-wide guidance does not confirm permission for a particular parcel. Check official zoning, overlays and permits. How verification works →

Municipal evidence check — October 12, 2026

Checked against municipality-published material: Orangeville passed ARU Zoning By-law Amendment 2025-011 on February 10, 2025; the 2026-01 townwide housekeeping height revisions appear in a public-meeting proposal and cannot be treated as adopted on that notice alone.

Outstanding: Check the signed 2025-011 text, outcome of 2026-01 proceedings, zone setbacks/access and permit review.

Verification status: Targeted municipal-source check completed. This is not an independent certification of all enacted bylaw amendments, zoning maps or any individual property.

Official Orangeville sources

Reviewed October 7, 2026. This is a planning summary, not a permit decision. Confirm current zoning, servicing, title constraints and permit requirements for the specific property before design or construction.
