Selling · Certificate of location · Blainville
In Blainville, the builder's certificate of 2013 shows neither the pool of 2017 nor the shed of 2021. Here is what the surveyor checks, what it costs and when to order it.
In Blainville, the certificate of location is the document the notary and the lender require to close a sale: prepared by a land surveyor, it describes the current state of the premises (boundaries, buildings, servitudes, encroachments, compliance). The seller provides it at their expense if it is outdated or inaccurate. Blainville is a city of recent homes on wooded lots, most delivered with a builder's certificate that the in-ground pool, the shed, the terrace and the fence added since have made inaccurate, even if it is less than ten years old; the setbacks on wooded lots and the drainage servitudes of the new sectors are checked. Count $1,200 to $2,500 and 4 to 8 weeks.
It is the land surveyor's report describing the current state of the property: lot boundaries, position of the buildings, servitudes, encroachments and compliance with by-laws. In a sale, the standard rule of the brokerage forms (clause 10.1) requires the seller to provide, at their expense, a certificate that reflects the current state of the premises; if it is outdated or inaccurate, the new one is on the seller. The law gives it no expiry date: the test is accuracy, but notaries and lenders in practice require a certificate of at most about ten years with no change since (pool, shed, extension, fence, cadastral renovation). The full detail is on our page certificate of location in Quebec.
Blainville (QPAREB sector 28, an $800,000 median in the second quarter of 2026, 27 days, the North Shore's most expensive market) grew by whole sectors from 1990 to 2020: Fontainebleau, the Domaine, Chambéry, La Fontaine, the Plateau. Each home was delivered with a builder's certificate of location, which owners keep as if it were permanent. Ten years later, it shows neither the in-ground pool, nor the shed, nor the covered terrace, nor the spa, nor the fence, nor the garage extension: it is outdated, and the notary or the lender demands a new one. On the wooded lots of Fontainebleau and the Domaine, the surveyor checks the setbacks, the protection strips of the streams and the wooded areas protected by the City's by-laws, and the servitudes of drainage and public utilities between neighbouring lots, very frequent in the developments of the 2000s. In the centre and near the 640, the 1970s to 1990s bungalows and cottages have the usual additions: pool, carport, extension. For a house at $800,000 that sells in 27 days, a certificate ordered at the decision to sell avoids losing the buyer during six weeks of waiting, and a certificate that reveals a shed on the protection strip is handled before the offer, not after.
| Blainville (QPAREB, Q2 2026) | Median | 1 year | 5 years | Days |
|---|---|---|---|---|
| Single-family | $800,000 | 8% | 42 % | 27 |
| Condo | $428,500 | 3% | 51 % | 53 |
A certificate of location stops being "current" as soon as something is added to the lot. Yet in Blainville, of the 300 houses sold on Centris between September 16, 2025 and September 16, 2026, 54% had a pool and 63% a garage: together with the shed, the fence and the extension, these are the most frequent additions that make the original certificate obsolete. And 19% of these houses were built before 1980: if their last certificate dates from the previous purchase, it is often more than ten years old, the limit notaries and lenders apply in practice.
| Addition | Share of houses sold | Median price with | Median price without |
|---|---|---|---|
| A pool | 54% | $865,000 | $600,000 |
| A garage | 63% | $897,500 | $555,000 |
Source: Centris (Matrix), single-family sales closed between September 16, 2025 and September 16, 2026, up to 300 per city, aggregates only. The pool and the garage also raise the price; the detail is in our page on what a pool and a garage are worth in Blainville. For the certificate, the consequence is simple: if one of these was added since the surveyor's last report, a new one is needed, and the seller pays for it.
On 500 sales in Blainville in 12 months, the median time between listing and acceptance is 12 days (half of the sales close between 5 and 37 days). A sale that goes above the asking price closes in 6 days; a sale below asking in 23,5 days, and that is the case for 63% of transactions, with a median discount of $19,900 (2.4%). A certificate ordered after acceptance adds four to eight weeks to that calendar, and a lingering "subject to the certificate" condition gives the buyer a reason to renegotiate.
The other figure to know: in Blainville, 32% of the listings that ended in 12 months were withdrawn, expired or cancelled without a sale (310 against 647 sold), and the withdrawn ones asked 36.5% more than the sold ones. The certificate is not the first cause, the price is; but an incomplete file stretches the delay, and the delay ends up costing the price. The detail is in how much people really negotiate in Blainville and the houses that do not sell in Blainville.
The median sale price of a house in Blainville is $709,000. A new certificate costs $1,200 to $2,500 depending on the property, or 0.2% to 0.3% of the price. The median discount granted by sellers who accept below asking is $19,900, and a missing certificate is exactly the kind of argument a buyer uses to get it. Ordering the certificate before listing, when it is outdated or inaccurate, therefore costs less than discovering it at the offer: that is the rule the team applies on every sale mandate in Blainville.
Count generally $1,200 to $2,500 depending on the property and the region, and above all 4 to 8 weeks of delay. That is the number one reason we ask our sellers to order it as soon as they decide to sell, not at the promise to purchase: a certificate that arrives late delays the notary, and a certificate that reveals an encroachment at the last minute derails the sale. The shed on the neighbour's line or the pool too close to the boundary are discovered here, not after signing.
Our other data series for Blainville, drawn from Centris listings:
Each page is recalculated from the past year's actual sales, aggregates only.
If it is less than about ten years old AND nothing has changed (no construction, extension, pool, fence, cadastral operation or new by-law), it generally passes with the notary and the lender. Otherwise, plan on a new certificate.
The seller, under the standard clause of the brokerage forms, if theirs is outdated or inaccurate. If their certificate reflects the current state of the premises and the buyer or their lender demands a new one anyway, it is on the buyer.
4 to 8 weeks in 2026 depending on the workload of the region's land surveyors. Order it as soon as you decide to sell.
