Aurora ARU design

Permit-ready plans for additional residential units in Aurora

An additional residential unit can create a separate home for family, long-term tenants, or changing household needs. Aurora also uses the terms secondary dwelling unit and third dwelling unit in its permit and registration materials.

ESCL Design prepares code-conscious drawings for new units and for existing basement apartments that need a permit and documented compliance path.

Local permit pathway

How Aurora’s permit and registration process fits together

1. Confirm the property
Review zoning, the proposed number and location of units, parking, servicing, and property-specific constraints before finalizing a design.
2. Prepare permit drawings
Document existing conditions and develop plans, code information, and construction details for the proposed unit and required upgrades.
3. Submit electronically
Aurora accepts permit applications through its portal, by email, or on a USB drive. A separate plumbing permit may be required for some work.
4. Complete inspections and registration
Required construction and inspections must be completed, followed by the Town’s applicable registration process for the additional unit.

Frequently asked questions

Aurora second dwelling unit questions

Do I need a building permit for a second dwelling unit in Aurora?

Yes. Creating or legalizing an additional residential unit normally requires building permit review. Depending on the work, Aurora notes that a separate plumbing permit may also be required.

Does the unit need to be registered with the Town?

Aurora has an Additional Residential Unit registration by-law and provides a Registration Application for a Secondary or Third Dwelling Unit. Confirm the steps and required inspections for your property directly with the Town.

Can you help with an existing basement apartment?

Yes. We can measure visible existing conditions, prepare as-built and proposed compliance drawings, and support the drawing portion of a retroactive permit application. Concealed construction, corrective work, or additional professional reports may be required.

Can drawings be submitted online in Aurora?

Yes. Aurora accepts electronic permit applications through its online portal, by email, or on a USB drive. The Town publishes file-format, naming, legibility, and submission requirements for electronic plans.
