Condo Renovation Rules: What the Board Will and Will Not Allow

In a house, the limits on a renovation are the building code, the permit and what you are willing to spend. In a condominium there is a fourth limit, and it comes first: the condo renovation rules of the corporation you bought into — the declaration, the by-laws, the rules themselves, and whatever the board and property manager require before a tool comes out of the van. They decide what you are allowed to change, who has to approve it in writing, and how the work is carried out in a building where several hundred other people live.

None of it is negotiable once the job has started. A board that discovers unapproved work can require the unit to be put back the way it was and charge the cost to the owner, which is a far worse outcome than being told no in advance. What follows is what those documents usually say in Toronto and the GTA, how approval actually works under Ontario law, and the places where suite renovations most often come apart.

What do condo renovation rules actually control?

Three things: which parts of the suite you are legally allowed to change, what the corporation must approve in writing before you change them, and how the work is run day to day. The finishes are yours. Almost everything behind and beneath them is shared, and shared things have an owner who is not you.

The reason is physical, not bureaucratic. The drain your sink empties into is shared with every suite on the stack. The slab your floor sits on is the ceiling of the unit below. The corridor your materials travel down is insured by the corporation, not by you. Each of those facts is already written down as a rule before you arrive, and a kitchen or bathroom in a condominium has to be designed around them.

Where does your unit end and the building begin?

At a boundary defined in the declaration, not at the wall you can see. Most Toronto declarations put the unit boundary at the unfinished surface of the slab, the interior face of the perimeter walls and the underside of the structural ceiling. Everything on your side is generally yours; everything on the other side is a common element, and some of what looks like yours is an exclusive-use common element you may use but not alter.

Two practical consequences follow. First, the layout has to be designed around the riser, the slab and the panel rather than around a photograph — the same discipline that decides a kitchen layout in a house, with fewer options available. Second, check the phrase "it is only cosmetic" against the declaration before using it in a submission, because the boundary it assumes is defined there and not by appearance.

When do you need an alteration agreement?

When the work touches the common elements or changes a service the corporation provides. Section 98 of Ontario's Condominium Act, 1998 requires an owner making an addition, alteration or improvement to the common elements to have a written agreement with the corporation, approved by the board and registered on title. A purely in-suite, finishes-only job usually falls outside it — the corporation's own renovation rules still apply.

The agreement does not expire when the work does. It typically records that the owner pays for the alteration, that the owner and every future owner of the unit is responsible for maintaining, repairing and insuring it, and that the corporation can require its removal in certain circumstances. Because it is registered on title it follows the unit to the next buyer, which is why boards are careful about what they sign. Ask the property manager early which category your scope falls into.

What will a condo board almost never approve?

Anything that changes the building rather than the suite. The list below is close to universal across GTA buildings, and an experienced property manager will stop most of these at the first email rather than take them to the board:

• A new penetration through the exterior wall, the roof or a balcony slab — a ducted range hood, a dryer vent, an air-conditioner sleeve
• Replacing or altering windows and balcony doors, which the corporation replaces on its own capital schedule
• Changing the suite entry door, its frame, closer or hardware, because the assembly is rated and belongs to the corridor
• Anything fixed permanently to the balcony: screwed-down decking, mortar-set tile, a permanent screen, a gas line
• Moving a riser, a waste stack or the suite's main shut-off valve
• Coring or cutting the slab without engineering. Many Toronto towers use post-tensioned slabs, where an uncharted cable is a serious hazard, so coring is refused without scanning and a written review
• Removing or notching a column, a shear wall or any wall the structural drawings show as carrying load
• Adding a bathroom, a laundry or any new wet area where the declaration does not permit one
• Construction debris down the garbage chute, or materials staged in the corridor
• Work, deliveries or noise outside the hours set in the rules

A refusal on any of these is not about the design. Each one would leave the corporation carrying a repair or a liability attached to the building itself, long after the unit has changed hands.

What does the corporation ask for before it says yes?

A package, not a conversation. Most GTA buildings ask for the same set of documents, and assembling all of it before the first submission is the cheapest way to keep a renovation moving — an incomplete package usually goes back to the owner rather than forward to the board.

Why does flooring cause more trouble than anything else?

Because it is the one change the neighbours can hear. Most declarations either require broadloom over a stated proportion of the floor area, or allow hard surfaces only over an acoustic underlay meeting a minimum impact rating, with the product data submitted for approval before installation. The rule is specific to the building, it is written down, and it is enforced after the fact by complaints from below.

Three things make it go wrong. The underlay is ordered with the flooring before anyone reads the clause, and the rating that arrives is below the one the building specifies. The underlay's thickness changes the finished floor height, and with it the entry threshold and every door undercut — cheap to settle before installation, expensive after. And nobody keeps the data sheet, so when a complaint arrives there is no record of what went down. Read the clause, submit the data sheet, then order: anyone doing flooring installation in a condominium should be asking for that clause before quoting.

What about plumbing, venting and the electrical panel?

These three decide more condo layouts than any design preference does, and all three are settled by the building rather than by the drawing. Work them out before the design is fixed, not after:

• Plumbing. Fixtures can usually be replaced where they stand. Moving a drain depends on how much fall is available within the suite, because the slab cannot be cut to drop a new line. In a great many suites the honest answer is that the toilet stays where it is and the layout is designed around that.
• Venting. Most suites have no route to the exterior, so a ducted range hood is not an option and a recirculating hood is the norm. The bathroom exhaust ties into a shared shaft, and its air flow is set by the building's system, not by fitting a more powerful fan.
• Electrical. The suite panel has the capacity it has. An induction range, heated floors, a steam shower and a car charger each want a dedicated circuit, and the total has to be checked against the panel while the layout is still on paper.
• In-suite laundry where there was none. This is a plumbing, venting, electrical and acoustic question at the same time, which is why it is the request boards refuse most often.

Does board approval replace a building permit?

No. They are two separate systems and either one can stop the job. The City's permit is about the Ontario Building Code; the corporation's approval is about the declaration and the other residents. Some work needs neither, some needs one, and structural or plumbing changes can need both — in that order, because the corporation will usually want to see the permit.

Which side of that line your job falls on is worth settling before the drawings are finished. We wrote up the municipal half separately in which Toronto renovations need a permit and which do not; the condominium half is the corporation's own paperwork, and neither one substitutes for the other.

What does the approval process usually look like?

Roughly the same sequence in most GTA buildings, with the length of each stage depending on the board's meeting cycle and whether a consultant has to review anything. The stages that stall are almost always the ones started late.

What actually goes wrong in a condo renovation?

Usually the paperwork or a booking rather than the construction, which is the same pattern behind why renovation timelines slip generally: the trade is on site waiting for something nobody scheduled. These are the condominium versions of it:

• The layout was drawn from a real-estate floor plan, so the riser turned out not to be where the plan showed it
• The underlay was ordered before the clause was read, and the rating that arrived was below the one the building requires
• The service elevator was not booked, so a delivery day became a waiting day and the trade was lost to another site
• A shut-off was requested for a date the building could not give residents notice for
• A wall came down that the structural drawings show holding something
• The hood was designed to duct through an exterior wall that cannot be penetrated
• The unit below was never told anything, so the first the property manager heard of the job was a complaint
• The contractor's insurance did not name the corporation, and the crew was turned away at the front desk on day one

Every one of those is avoidable by reading first. Ask the property manager for the declaration, the rules and any renovation policy before a layout is drawn, and design the suite around what they allow rather than discovering it at submission. There is finished work at full size in the project gallery, and the way we approach condo and apartment renovations, kitchen renovations and bathroom renovations starts with the building's paperwork.
