Ottawa Condo Renovation Rules:
What You Can and Can't Do

A homeowner in a Centretown condo called us about a kitchen renovation. Standard scope: new cabinets, new island, move the dishwasher to the other side of the sink. They had collected three quotes from contractors who all said "no permit needed."

We pulled their condo declaration and the rules from the property manager. Moving the dishwasher meant rerouting the drain, which crossed the slab into common element plumbing. Before any work could start, the project required a written application to the board, an engineer's letter confirming the slab penetration, a refundable deposit for elevator and common-area protection, and a building permit through the City.

Condo renovations in Ottawa run by their own rulebook on top of the Ontario Building Code. Here is what you actually need to know before you sign a contract.

The Condominium Act and Why Your Unit Isn't Really "Yours"

The Ontario Condominium Act, 1998 creates a legal framework that splits a condo building into three categories of space:

• Unit. The space inside your unit boundary, as defined in the condo declaration. Usually the inside face of the perimeter walls, excluding structural slabs and shared chases.
• Exclusive-use common element. Spaces you have the exclusive right to use but that the corporation owns: balconies, parking spaces, lockers, sometimes patios.
• Common element. Everything shared: lobbies, hallways, elevators, structural slabs, exterior walls, the building's plumbing risers, the HVAC main equipment, and so on.

You own the unit. You do not own the wall studs, the slab, the windows in most buildings, the in-slab plumbing, or anything outside your defined boundary. The renovation rules flow from this distinction.

Read the Declaration and Rules First

Every condo corporation has three governing documents. Before any renovation, get all three from your property manager:

1. Declaration. The legal document that defines unit boundaries, exclusive-use elements, and what owners are responsible for.
2. By-laws. Rules that govern operation of the corporation, including renovation approval procedures.
3. Rules. Day-to-day rules the board can change without owner vote: hours of work, deposit amounts, insurance requirements.

Together, these dictate what you can and cannot touch, who has to approve it, and what conditions the board can impose. Buildings vary wildly. We have done renos in 1980s Ottawa concrete towers where the board approves anything in 48 hours; we have done renos in newer mixed-use buildings where every floor change requires an acoustic engineer's report and 12 weeks of review.

What You Almost Always Can Change

Inside the unit boundary, with permission, the following are generally fair game:

• Non-load-bearing interior partition walls
• Cabinetry and built-ins
• Finishes: flooring, tile, paint, ceiling treatments
• Light fixtures, electrical outlets, switches (within unit)
• Plumbing fixtures (toilet, sink, faucet, tub) where the supply and drain lines are within the unit
• Interior doors

The catch: even where the change is permitted, most condos require a written renovation request, board or property manager approval, proof of contractor liability insurance (multi-million-dollar coverage is typical), and sometimes a deposit refunded after the work is inspected.

What You Almost Never Can Change

Common element items the board will refuse to approve in almost every Ottawa condo:

• Exterior walls, exterior windows, exterior doors (the building's enclosure)
• Balcony railings, balcony surface, balcony glazing
• Anything on the building exterior visible from outside
• Structural slabs (no penetrations through floors except where the declaration specifically allows)
• Building plumbing risers, HVAC mains, electrical risers
• Fire alarm devices, sprinkler heads (these can be relocated only with a fire engineer's report and full permit)

The reason is liability. The corporation insures the building shell and shared systems. A change that affects either gets the insurance company involved, and most boards will not take that risk for a single owner's renovation.

The Plumbing Trap

Moving plumbing is the single most common condo renovation issue. The rule that catches people off guard:

The plumbing fixtures inside your unit are usually yours. The drain and supply lines that run through the slab to reach the building's risers are usually common element. So while you can change the toilet, you often cannot move where it sits, because the drain stub is fixed in the slab.

Practical impact:

• Replacing a toilet in the same spot: usually no approval needed, just a permit if the rough is being modified
• Moving the toilet 12 inches: requires slab modification, engineering, and board approval
• Adding a second bathroom: almost never possible without major structural review and a new connection to the building riser, if the building can accommodate it at all
• Changing the dishwasher location: depends on whether the existing drain serves it directly or whether new under-slab piping is needed

Before you commit to a kitchen layout that moves the sink or dishwasher, get an engineer to confirm whether the slab can be opened. In post-tensioned concrete buildings (most Ottawa condos built after 1990), the answer is often no.

Status Certificate Review

Before any major renovation, request a status certificate from the corporation. The status certificate is a comprehensive package that includes:

• The current declaration, by-laws, and rules
• The most recent reserve fund study
• Audited financial statements
• Any current or pending lawsuits or special assessments
• Confirmation of the unit's good standing

The status certificate carries a modest statutory fee and the corporation has 10 days to deliver it. The cost is worth it; we have walked away from condo renovations after reading status certificates that revealed pending special assessments per unit, which would have been added to the renovation budget by surprise.

Contractor Requirements

Most Ottawa condo boards impose contractor-specific requirements before approving any work:

• Liability insurance. A multi-million-dollar minimum, often higher, with the corporation named as additional insured
• WSIB clearance. Active certificate required at start and end of project
• Damage deposit. Held until completion, applied against any common-area damage
• Move-in / move-out fees. Charged each way for elevator and lobby protection
• Working hours restrictions. Typically 8 AM-5 PM weekdays, no statutory holidays, often no Saturdays
• Loud-work restrictions. Demolition and tile cutting often restricted to 9 AM-4 PM
• Material delivery scheduling. Through a service entrance, with elevator booked in advance

A contractor who has never worked in your building will not know any of this until they show up on day one and get sent home. We always recommend asking for the building's renovation guide and reading it cover to cover before signing.

The Approval Timeline: 4-12 Weeks

From "I'd like to renovate" to "approved, you can start," the typical Ottawa condo timeline:

1. Week 1. Order status certificate, read declaration and rules.
2. Weeks 2-4. Design the renovation, including engineer's letter for any slab penetration.
3. Week 4. Submit renovation application package to property manager: drawings, contractor info, insurance certificates, scope description, schedule.
4. Weeks 5-8. Property manager reviews, may ask questions, forwards to the board.
5. Weeks 6-12. Board reviews at next meeting (often monthly), issues decision.
6. After approval. If a building permit is required, that is a separate 4-8 week City review.

The total from "I want to renovate" to "the contractor can start swinging hammers" is typically 8-16 weeks. Anyone who tells you they will start in two weeks has either skipped the approval or already done it for you.

"In a condo, you don't own walls; you own air space. The walls are the corporation's. Every reno conversation starts with that fact."

When You Need a Building Permit

The City of Ottawa permit rules apply equally to condos. You need a building permit through MyServiceOttawa (minimum $117) for:

• Any structural change
• Any plumbing modification beyond fixture replacement
• Any electrical work beyond like-for-like fixture replacement (and ESA notification regardless)
• Removing or relocating a non-load-bearing wall in some cases
• Any change that affects a fire separation

The permit is in addition to, not in place of, the condo board's approval. A unit owner cannot apply for the permit until the board has signed off, because the City requires evidence the corporation has authorized work that affects common elements.

What Drives Renovation Pricing Inside Ottawa Condos

Scope determines the budget. From lightest to heaviest, here is what each tier of condo work includes and what pushes its pricing:

• Bathroom refresh: new vanity, toilet, tile, and paint with no fixture relocation. Priced mainly by finish level and tile selection.
• Full bathroom gut (no fixture relocation): adds demolition, waterproofing, and new substrate. Plumbing stays put, so cost is driven by waterproofing detail and finish grade.
• Kitchen refresh: new cabinets, counters, and paint in the existing layout. Cabinetry grade and countertop material are the main cost drivers.
• Full kitchen gut with island move and electrical changes: adds layout changes, electrical reconfiguration, and possible slab work. Plumbing and electrical complexity drive the price.
• Whole-condo renovation: priced per finished square foot, scaling with finish level, layout changes, and the engineering reviews the building requires.

Condo work runs higher than the same scope in a detached house because of access, insurance, restricted hours, and the engineering reviews most projects need. We put every line in a detailed written breakdown so you can see exactly what each tier includes before you commit. Plan for it.
