A homeowner in a downtown Ottawa condo tower orders new blinds, picks a colour she loves, and gets them installed the same week. Two weeks later, a letter from the property manager asks her to remove them because the fabric backing doesn’t match the building’s exterior. This happens often enough that it’s worth checking the condo window covering rules Canada buildings actually enforce before you order anything, not after.
Condo declarations and rules almost always say something about what can be visible from outside a unit, and window coverings are one of the most commonly regulated items on that list. The rules aren’t the same everywhere, they aren’t always written clearly, and enforcement ranges from a friendly reminder to an actual fine — in at least one case, all the way to a formal tribunal ruling.
Why condo buildings regulate what’s on your windows
A condominium corporation’s declaration typically splits the building into “common elements” (the exterior walls, hallways, structure) and individually owned “units.” Windows themselves usually sit right on that boundary. The glass and frame are often common elements maintained by the corporation, while everything on the inside of the glass belongs to the owner. Because the outward-facing side of a blind or shade is visible from the street, parking lot, or courtyard, most declarations treat it as something that affects the building’s appearance, which gives the board grounds to regulate it even though the blind itself is your property.
Boards generally frame this as protecting resale value and a uniform look rather than controlling personal taste. A patchwork of different colours and materials across one façade is the thing the rule is trying to prevent, not your choice of fabric inside the unit.
The condo window covering rules Canada buildings share most: white or neutral facing out
Across condo declarations and rules and regulations packages in Ontario, the most common single requirement is that any window covering visible from outside must show white, off-white, or another neutral colour on the exterior-facing side. Reflective materials, foil-backed film, and exterior-mounted coverings are usually flagged separately as prohibited outright, since they change how the whole building looks from the street rather than just one unit.
Where that rule actually lives varies by building. Sometimes it’s in the declaration itself, sometimes it’s buried in a separate rules and regulations document the board can amend without a unit-owner vote, and sometimes both documents touch on it with slightly different wording. A five-minute email to the property manager asking for the current window covering clause, before you order, is cheaper than a return shipment after.
What happened when a B.C. owner ignored the rule
A useful real-world example comes out of a Surrey strata building, Strata Plan NW2603. An owner, Heather Anne Prenty, installed a brown sunshade on her balcony without asking the strata council first. The bylaw required window coverings visible from outside to be white or off-white, and the strata fined her $200 for breaking it.
She took the fine to British Columbia’s Civil Resolution Tribunal, and on September 16, 2022, the tribunal member sided with her on a technicality: a sunshade hanging on a balcony railing isn’t a “window covering” in the way the bylaw meant, so the colour rule didn’t actually apply to it. The tribunal cancelled the $200 fine and ordered the strata to refund it along with $112 in tribunal fees. It also made clear she still needed the strata’s written approval before putting anything back up, just not because of the colour.
These rules aren’t toothless: boards do issue real fines over window coverings, disputes over the exact wording of a bylaw can go all the way to a tribunal, and approval-before-installation is the step that actually protects you, regardless of which way a colour argument might go.
Why some declarations say nothing about window coverings at all
Not every building has a window covering clause, and the reason usually comes down to age and construction type. Older low-rise conversions and smaller buildings drafted before window coverings became a common design complaint often left the topic out of the original declaration entirely. Newer mid- and high-rise towers, especially anything built in the last fifteen years with large curtain-wall glass facades, tend to have detailed rules from day one, because the developer’s architect specified an exterior look and the board inherited the job of protecting it.
If your declaration is silent, that’s not the same as permission to do whatever you want. Boards can still pass a new rule under the Condominium Act’s general authority to regulate common elements and units, and that new rule can apply going forward even in a building that never had one before. An owner who installs dark curtains in a rule-free building today has no guarantee the building stays rule-free for the life of those curtains.
Ontario condos: where to find your building’s actual rule
Ontario condo corporations operate under the Condominium Act, 1998, which sets out the difference between a declaration, by-laws, and rules, and gives the board authority to make rules governing the use of units and common elements as long as they’re reasonable and consistent with the Act. Window covering colour requirements are almost always a “rule” in that legal sense, not a clause buried in the Act itself. That’s why two buildings ten minutes apart in Ottawa can have noticeably different requirements.
Where things get more involved is motorization or anything that requires running wiring, adding a hard-wired hub, or altering the window opening itself. If a change touches the common elements rather than sitting entirely inside your unit, some boards will ask for a formal alteration agreement before work starts. That’s a separate conversation from colour, and it’s worth having with your property manager before booking an installation date, not after the installer is already on site.
Montréal condos: le règlement de l’immeuble and French-language paperwork
Québec uses different terms for the same idea, and the Government of Québec’s co-ownership guidance is a useful starting point for the general framework. A syndicat de copropriété governs the building, and the window covering requirement — when there is one — usually sits inside the règlement de l’immeuble rather than a document called a “declaration.” The underlying logic matches Ontario: anything visible from the exterior of the building is treated as affecting the collective appearance of the property, and boards can restrict it even though the blind belongs to the owner.
The practical difference for Montréal owners is paperwork. Property managers frequently want product specification sheets, warranty documents, and correspondence in French, and a supplier that can only produce English spec sheets slows down an approval that should take a week down to something that drags into a month. This is one of the reasons Zenith Shade keeps French-language support available for Montréal clients specifically for the condo-approval conversation, not just the sales conversation.
What’s usually allowed versus what needs a closer look
| Feature | Usually allowed | Usually restricted or needs approval |
|---|---|---|
| Exterior-facing colour | White, off-white, light neutral | Dark colours, patterns, bold prints |
| Fabric backing | Solid white or reverse-white liner | Reflective foil, mirrored, metallic film |
| Mounting style | Inside-mount, within the window frame | Exterior-mounted or balcony-hung coverings |
| Standard motorization | Battery or plug-in motors on existing wiring | New hard-wired hubs or structural changes |
| Colour on the room-facing side | Any colour or pattern the owner wants | Not restricted in most declarations |
That last row is the one most owners are relieved to hear about. Almost every rule this article turned up regulates the outward-facing side only. The side facing your living room is your decorating decision, not the board’s.
How to choose blinds that pass approval the first time

Dual-colour roller blinds solve most of this in one order: pick whatever shade or pattern you want on the room side, and the fabric ships with a solid white backing on the reverse. Custom roller blinds are typically made this way already, so the “approved on one side, yours on the other” outcome doesn’t require a special request.
Zebra blinds and cellular blinds can usually be specified with a neutral or white-facing fabric as well, which matters if your building’s rule doesn’t distinguish between blind types and just says “white facing outward” for anything in the window. Cellular shades have the added benefit of a honeycomb structure that reads as a clean, uniform white or grey from the street regardless of the interior colour, which is one reason they show up so often in condo buildings with strict façade rules.
Motorized blinds don’t change the colour equation at all — a motor sits inside the headrail and doesn’t affect what’s visible through the glass — but if your building requires alteration approval for anything touching the common elements, mention motorization specifically when you ask, since some boards treat it differently from a purely manual installation.
Before ordering, measure carefully using a proper window shade measuring guide so the sizing is right the first time, since a rejected or ill-fitting order in a condo often means a longer wait for a second approval round, not just a quick reorder.
A practical approval checklist before you order
Use this checklist to work through the condo window covering rules Canada requires before you place an order:
- Ask your property manager for the current window covering clause in writing, rather than relying on what a neighbour says the rule is.
- Confirm whether the requirement covers colour only, or also mounting style and motorization.
- Choose a dual-colour or reverse-white fabric so the outward-facing side is compliant by default.
- Keep the product spec sheet and, in Québec buildings, request it in French for the board’s file.
- Submit for approval before installation, even if you’re confident the colour is fine — the paperwork protects you if a rule gets reinterpreted later.
None of this is complicated once you know to ask. The owners who run into trouble are almost always the ones who assumed a rule didn’t apply to them rather than the ones who checked and got a surprising answer.
Already installed something that doesn’t comply?
A property manager’s letter about non-compliant blinds is typically a heads-up rather than a formal enforcement notice, and responding quickly with a plan tends to go better than waiting for a follow-up. Two options generally work: swap the fabric insert or liner if the blind system supports it, which is often possible with cellular and roller styles without replacing the whole headrail, or order a compliant replacement and keep the current one for a different room where it isn’t visible from outside, like an interior hallway or a window facing a shared wall rather than the street.
Either route is cheaper and faster than the alternative of ignoring the letter and ending up in the same position as the Strata Plan NW2603 case above, where a fine turned into a tribunal filing over a $200 dispute. Most boards would rather see a resolution timeline than a fight.
Frequently asked questions
Do all condos in Canada require white-backed blinds?
No. It’s common but not universal, and the exact wording — white only, off-white acceptable, any light neutral — varies from one declaration or règlement de l’immeuble to the next. Check your own building’s document rather than assuming a rule you heard about from another building applies to yours.
Can a condo board actually fine me over the wrong blind colour?
Yes, and the B.C. Civil Resolution Tribunal case involving Strata Plan NW2603 shows boards will issue and defend fines like this, sometimes for a few hundred dollars. Whether a specific fine holds up can come down to fairly technical wording, like whether a covering was ruled to be a “window covering” at all under that building’s bylaw.
Do curtains and drapes need approval too?
Generally yes, if any part of them — the lining, the fabric, a visible rod — is visible from outside the unit. Sheer curtains with a coloured or patterned lining are one of the more common surprise rejections, since owners often don’t think of curtains as falling under a “blinds” rule.
Is a formal alteration agreement needed just to install blinds?
Usually not for a standard inside-mount installation that doesn’t touch the window frame or common wiring. It becomes more likely once motorization requires a hard-wired hub or any structural change, which is worth flagging to your property manager as part of the condo window covering rules Canada boards ask about before approving an order.
What about rental apartments rather than owned condos?
Landlords can set similar rules through a lease, and buildings with a mixed rental and ownership base sometimes apply the same condo-wide exterior appearance rule to every unit regardless of tenure. If your lease is silent on it, ask before you install anything permanent — a quick email costs nothing, and a removal request after installation usually does.
My building’s declaration doesn’t mention window coverings. Am I free to choose anything?
For now, likely yes. Long-term, treat it as an open question rather than a guarantee. Boards can add a rule later under their general authority to regulate common elements and unit appearance, and that new rule can apply to coverings you already own.
