A client in a Centretown condo emailed last fall asking why his renovation was paused. Answer: his neighbour had filed a complaint about noise, the property manager had stopped the freight elevator booking, and the board was now reviewing whether his alteration agreement allowed any of the work he'd authorized. We were on day eight of a planned six-week project. We didn't get back in for nine days.
Condo renovations in Ottawa fail for one reason more than any other: the homeowner skipped or rushed the board approval process. Here's how to do a condo renovation in Ottawa the right way, and what the board actually cares about.
Before anything else: read your declaration and rules
Every Ontario condo corporation has three governing documents. They're available from your property manager and from the corporation's website. You need to read all three before you start designing anything:
- Declaration. The original incorporation document. Defines what's "unit" versus "common element." This matters because you can't touch common elements without board permission, ever.
- By-laws. Operational rules adopted by board votes. Often include alteration procedure, indemnity requirements, and approved trade qualifications.
- Rules. Day-to-day living rules. Includes noise hours, freight elevator booking, contractor sign-in procedures, and parking.
The declaration is the most important. It tells you, for example, that the slab beneath your floor is common element (you can't drill into it without permission), that the windows are common element (you can't replace them yourself), and often that the in-suite plumbing risers are common element (you can renovate around them but not relocate them).
The alteration agreement
Almost every Ottawa condo over 50 units has a formal alteration agreement process. Submission package usually includes:
- Detailed drawings (architectural and mechanical) showing what's being changed
- Contractor's WSIB clearance certificate
- Contractor's general liability insurance, to the coverage limit the building requires
- Plumber's and electrician's licences plus ESA permit numbers
- City of Ottawa building permit (if structural or major plumbing/electrical)
- Indemnification agreement signed by the unit owner
- Security deposit (set by the corporation, refunded after inspection)
The board reviews this in their next monthly meeting. That timeline alone is the silent killer of condo renovations. If you submit on May 12 and the board meets June 15, you've burned a month before approval. Submit drawings four to six weeks before your intended start date, minimum.
The "no work above 6pm" rule
Almost every Ottawa condo prohibits noisy work outside 8am-5pm Monday-Friday and 9am-4pm Saturday, with no Sunday work. Some buildings ban Saturday work entirely. Plan your timeline assuming a 5-day work week, not 6 or 7. A 6-week project at home becomes 8-9 weeks in a condo.
What you can usually change, and what you can't
The dividing line in most Ontario condos is unit boundary versus common element. Here's the typical breakdown for a high-rise residential condo in Ottawa:
Almost always allowed (with notification)
- Cabinets, counters, sinks, faucets
- Flooring (within unit), provided you maintain the original IIC sound rating
- Interior paint and wall coverings
- Light fixtures and switches
- Bathroom vanities, toilets, mirrors
- Interior doors and trim
Allowed only with board approval
- Removing or modifying any wall (even non-load-bearing)
- Relocating any plumbing fixture
- Changes to the electrical panel or main feeders
- Bathtub-to-shower conversions (because of waterproofing implications for the unit below)
- Built-in cabinetry attached to common-element walls
- HVAC modifications, including replacing in-suite heat pump or furnace
Almost never allowed
- Window replacement (common element)
- Balcony enclosures or modifications
- Exterior alterations of any kind
- Relocating plumbing risers or main electrical feeders
- Penetrating the slab (common element)
- Changing the demising walls (the walls between your unit and the next)
The flooring problem most owners hit
This is the issue I see most often. The original carpet had an IIC sound rating of about 60. The owner wants engineered hardwood, which by itself has an IIC of about 35. The unit below files a complaint about footfall noise and the board orders the floor torn out.
The fix: a high-performance acoustic underlay. Products like Acousti-Tech 6500 (IIC 71) or QT Sound Control (IIC 73) underneath engineered hardwood maintain or exceed the original carpet rating. The board's alteration agreement will usually require IIC certification on the underlay you spec.
Cost: the certified underlay carries a per-square-foot premium over a standard product, so a full-unit floor adds a real line to the flooring budget. Worth every dollar; the alternative is replacing the floor twice.
"The unit below you is the most important opinion in your renovation. Make their floor your problem in the planning stage, not in the lawyer's office."
Plumbing: the buried trap
Most condo plumbing is sleeved through the slab and tied into vertical risers in the chases between units. You cannot move a kitchen sink across the room without rerouting drainage, and rerouting drainage in a slab is usually impossible.
What this means in practice:
- Kitchen sink can move 12-24" along the same wall, sometimes
- Kitchen island with sink: rare; needs a pump system or a specialty drain configuration
- Bathroom relocation: almost never possible without major slab work the board won't approve
- Adding a powder room: depends entirely on whether you can tie into the existing stack within 5-6 feet
For older Ottawa condos (built pre-1990, common in Centretown and the Glebe), the plumbing risers are often cast iron and shared between three or four units stacked vertically. Touching them affects everyone in the stack.
Electrical: capacity and panel rules
Most Ottawa condos have a 100-amp panel inside the unit. That's enough for the original layout but tight if you're adding a wall oven, induction range, or EV charger.
What's typically OK without a panel upgrade:
- New circuit for the dishwasher
- Replacing the gas range with an induction range (provided your panel has spare capacity)
- Adding kitchen pot lights
What requires special handling:
- EV charger: requires board approval and often capacity confirmation from the building
- Heat pump or new HVAC: usually requires board approval because of capacity and roof/exterior implications
- Panel upgrade: not always possible. Many condos have a fixed allocation per unit at the building's main switchboard.
An ESA permit is required for any electrical work. The contractor must give you a copy of the permit and the final inspection certificate; the board will ask for both.
Realistic timeline for a Centretown condo kitchen
For an 800-1,000 sq ft condo with a kitchen-and-flooring renovation:
- Weeks 1-3: Design, drawings, and contractor selection
- Weeks 4-9: Alteration agreement submission, board review, approval
- Weeks 10-11: Material ordering and elevator booking
- Weeks 12-19: On-site demolition and construction (8 weeks for a kitchen-and-floor reno)
- Weeks 20: Final cleaning, board inspection, security deposit refund
Total: 20 weeks. About double what the same project would take in a single-family house, almost entirely because of the board approval cycle and the 5-day work week.
How to keep the board on your side
Five things to do, in order of importance:
- Introduce yourself to your immediate neighbours before demolition. Slip a note under their door with start date, end date, and your phone number. The biggest cause of board complaints is owners who feel ignored.
- Use only contractors who've worked in the building before, if possible. Property managers keep informal lists. They know who follows the rules.
- Book the freight elevator the second you have approval. Most buildings limit alterations to one or two units at a time. A 9am Monday booking goes fast.
- Keep one clean common-area floor protection plan in place from day one. Hallway runners, elevator pads, lobby protection. The board notices.
- Use a single point of contact between contractor and property manager. Don't make the manager chase three subs.
