Do I need the condo corporation's approval to renovate my unit in Ontario?
Whether you need corporation approval depends on what you're renovating and what your governing documents say. Under the Condominium Act, 1998, you must obtain the corporation's written approval before making any alteration, addition, or improvement to the common elements or to those parts of the unit that the declaration designates as the corporation's maintenance responsibility. This commonly includes structural walls, HVAC connections, windows, and balconies.
Even for in-unit work that doesn't touch common elements — like replacing flooring or kitchen cabinets — many corporations require advance written notice and may impose conditions such as indemnity agreements, insurance requirements, and working-hours restrictions. Some declarations require approval for any work involving plumbing or electrical.
You should also check whether municipal building permits are needed for your specific work — that obligation runs alongside any condo approval requirement. Failing to get required corporation approval can result in a compliance order requiring you to restore the unit at your own expense.
Key takeaways
- Alterations to common elements always require written corporation approval.
- In-unit renovations often require notice and may require approval depending on governing documents.
- Building permits may be needed from the municipality independent of condo approval.
- Unauthorized alterations can lead to costly restoration orders.
