Aurora, ON suite & ADU rules

Permission first. Construction second.

Aurora enacted Additional Residential Units Registration By-law 6660-24 in December 2024, replacing its older registration framework. Some older Town guidance still cites the repealed 5429-12 bylaw; use 6660-24 for the current registration process.

What the municipal rules say

Aurora approved a 2024 registration bylaw for additional residential units.

What applies locally

Municipal council material confirms the Ontario three-unit framework: generally a principal home plus up to two additional units in allowed configurations. The registration bylaw ensures inspection and compliance.

Important limits and exceptions

A 2024 motion proposing four-unit as-of-right permissions is not proof that zoning was amended to allow four everywhere. Check current zoning and registration before claiming a fourth unit.

Before work begins: confirm the lot’s actual zoning, mapped overlays, legal parcel characteristics, servicing and applicable building permit conditions with the municipality.

Aurora registration and permits

Aurora requires registration of additional residential units under By-law 6660-24. Its municipal building guidance addresses permits, electrical inspection and registration; an older two-unit-house guide should not be interpreted as the full current ARU entitlement.

Before creating or legalizing a suite, confirm permitted unit count and configuration under the current zoning bylaw, obtain the relevant building or change-of-use permit, and complete the town’s registration and inspections.

Can you build here?

Here is the municipal framework; parcel eligibility is not verified in Aurora.

This is the simple build-direction summary. The exact property still has to meet its zoning, site, servicing and permit requirements.

Before you build: confirm the exact property, zoning and permit path with Aurora.

Next planning steps

Local rules still need verification before pricing before you request a quote.

This preliminary guide does not answer whether a particular parcel 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 evidence check · October 12, 2026

Confirmed for this claim: Aurora lists Additional Residential Units Registration By-law 6660-24, which replaces earlier two-unit registration arrangements. Its older Secondary Dwelling Units page still refers to repealed bylaw 5429-12 in parts, so readers must not follow that outdated registration reference.

Still to verify: Check zoning 6000-17 as amended, applicable third-unit permissions, registration under 6660-24 and the individual site.

This is a targeted official-source review, not complete certification of every adopted amendment or approval for your property.
