Condo Renovation Rules in Ontario (Status Certificate & Board Approval)
Renovating a condo in Ontario adds a layer houses do not have: the corporation's declaration and rules, board approval, and often an alteration agreement — on top of any municipal permit. Check your status certificate and declaration first. This is general guidance, not legal advice.

Renovating a condo in Ontario adds a whole layer that freehold houses do not have. On top of any municipal building permit, you are also bound by your condominium corporation's declaration, by-laws, and rules — and many changes need the board's written approval and sometimes a formal alteration agreement. The first step is not a contractor; it is reading your own governing documents.
Unit vs common elements
The core question in any condo renovation is what you actually own and control. Typically you own the interior of your unit, while structural elements, the building envelope, plumbing stacks, and many balconies or terraces are common elements or exclusive-use common elements managed by the corporation. Where the boundary falls is defined in your declaration — and it decides what you can change freely and what needs approval.

A guide, not a ruling — your declaration and board have the final say.
What condo renovations usually require
- Reading your declaration, by-laws, and rules — they govern what you may change and how.
- A current status certificate — it discloses rules, restrictions, and the corporation's financial and legal situation; your lawyer reviews it when you buy, and it is worth revisiting before a renovation.
- Board approval for anything touching structure, plumbing, electrical, HVAC, flooring over neighbours, or the building envelope.
- An alteration agreement — a formal contract with the corporation for changes to or affecting common elements, often assigning you ongoing responsibility for what you install.
- Any municipal building permit that the work would need in any home, in addition to the condo's own approval.
- Rules on noise, work hours, elevator and loading-dock booking, and contractor insurance requirements.
Common flashpoints
- Flooring — replacing carpet with hard flooring often triggers sound-transmission (STC) rules to protect the unit below.
- Plumbing and gas — kitchen and bathroom changes can involve shared stacks that are common elements.
- Balconies, terraces, and windows — usually exclusive-use common elements you cannot alter at will.
- Electrical panel or HVAC changes that affect shared systems or capacity.
FAQ
Do I need the condo board's permission to renovate?
For cosmetic work fully inside your unit, often not, but you should still confirm. For anything touching structure, plumbing, electrical, HVAC, flooring over another unit, or common elements, you typically need board approval and sometimes an alteration agreement. Your declaration and rules are the authority — check them first.
What is an alteration agreement?
It is a formal contract between you and the condominium corporation covering a change to or affecting common elements. It often makes you responsible for maintaining, repairing, or removing the alteration, and it can bind future owners of your unit. Because it has lasting legal effect, consider having a lawyer review it.
Where do I find my condo's renovation rules?
In your declaration, by-laws, and rules, and summarized in the status certificate. Your property manager or condo board can provide current copies. Rules change over time, so use the most recent versions and confirm directly before relying on them.
