Re-Sale of Leaky Condos: Did the Buyer Know?


British Columbia’s Homeowner Protection Office believes there is a total of about 65,000 dwellings in the province that are "leaky condos". As of 2002, 50,000 of them had been identified.

"Leaky condo syndrome" is defined as catastrophic failure of the building envelope allowing water to enter the envelope and leading to rot, rust, decay and mold. The syndrome has affected condominiums, detached homes, schools and hospitals.

Until the collapse of BC’s New Home Warranty Program in 1998, many real estate agents and others believed that the warranty company would repair most building envelope failures. However, only a small percentage of problems were resolved by the warranty provider.

The leaky condo crisis has been exacerbated by the sale of problem homes without full disclosure to subsequent buyers. This has occurred despite the fact that it has been customary for real estate agents to include standard clauses, recommended by the Real Estate Council of BC, in a Contract of Purchase and Sale mandating the use of investigative tools and declarations to bring maximum transparency to transactions.

The impact on people’s lives has been enormous, even horrendous in some cases. Some people have lost much or all of their life savings, even their homes. Family life, home-based businesses and health have suffered due to disruption and the mess during repairs, and the strain of it all.

A real estate researcher and licenced agent, Nancy Bain, conducted a study in 2002 to determine why home buyers of re-sale leaky condos were not aware of problems when they made their purchase. The intent of the research was to facilitate improvements in increasing the transparency of transactions.

Three possibilities were examined:

A selection criterion was that, within one year of purchase, the buyer discovered a material problem that had not been revealed at the time of purchase. Problem free transactions were not eligible for the study and the extent of problem transactions in the re-sale market was not examined. The researcher examined 40 transactions meeting this criterion. Of the 40, 20 were from Vancouver Island, and 20 were from Greater Vancouver and Fraser Valley. The transactions took place over a seven-year period, from 1996 to 2002 inclusive.

The sample group proved to be ‘information rich’, providing valuable insight on the questions posed by this research. However, the sample group does not represent the population of all failed transactions during the period studied. For example, two key groups of buyers not represented are those for whom English is not their first language and investors.

Sample group

Candidates were sought who met the following criteria:

The type of serious problem was not pre-defined, but in every instance, those selected had purchased a unit with building envelope problems. The requirement that a serious problem be discovered within one year of purchase made it almost certain that the problem existed at the time of purchase.

The majority of buyers – 27 of the 40, or almost threequarters – were aged 40 to 70.The same number had previously owned a detached home or a condominium, 11 had rented and two had lived in co-op housing. Half identified affordability as their main reason for buying a re-sale condominium. Four purposely bought re-sale condominiums to avoid the leaky condo problem, believing that an older building was less likely to have undetected problems.

The majority (33) had heard of the leaky condo phenomenon before they purchased, but they were not familiar with the extent of the problem. Most of the remaining seven who had not heard of the problem were from Alberta.

The majority of special assessments levied, which fund the cost of major repairs, ranged from about $25,000 to $60,000. Two assessments were much higher, with one at about $150,000 and the other just over $200,000. Such levies drastically affect people’s lives and cause financial hardship, and even ruin for some.

The following were among the reasons given for arriving at a purchase decision:

As to whether, in hindsight, the buyers thought there were any clues that a problem existed at the time of purchase, 24 said no. While four said there were signs in the strata corporation minutes, they did not have the minutes at the time of purchase. Three believed, after the fact, that certain design elements gave clues.Another three said there were physical clues but these had not been properly disclosed: they were otherwise explained away, hidden by furniture or not detected by a property inspector but readily apparent to a carpet cleaner.


Investigative tools

The investigative tools used in a BC condominium purchase to bring transparency to the transaction include:

Since 1999, contracts have more consistently required use of investigative tools. Still, there are buyers who discover serious problems within one year of purchase.

Property disclosure statement

Of all the investigative tools, the Property Disclosure Statement (PDS) was used the most frequently. Its purpose is to disclose hidden or latent defects known to the seller. Although the PDS should have identified problems in a number of cases, it failed to do so. This tool cannot and should not be solely relied on for a number of reasons:

Professional Property Inspections

This tool was used the least. Of the 40 cases, 29 did not have a property inspection, and none of the participants cited cost as the reason for not having one. It was found that the extent to which the exterior of a building is inspected varies greatly; the checklist format of the report sometimes buried significant information; and written comments by an inspector may appear benign but closer examination by a person knowledgeable about building envelope failure would reveal ominous warnings couched in soft language. Only one inspection report gave warnings in plain, simple language, which ensured the buyer understood the risk involved in purchasing. In eight cases, the reports should have caused alarm but they failed to do so.

Minutes of strata meetings

The minutes of a strata corporation and its strata council are considered an essential tool for a buyer in gaining insight on the knowledge and operations of the corporation. Half the contracts had a clause requesting minutes, although such a request did not appear as a standard clause until 1999. Prior to then, many BC real estate agents simply added this request to their contracts.

In the more recent period from 1999 to 2002 inclusive, minutes were requested 13 out of 14 times, but there were challenges for the buyers to benefit from this information:

Form B Information Certificate

Since July 2000, contracts have contained a request for a Form B Information Certificate. Its purpose is to disclose information about a strata corporation and the particular unit being purchased.The information disclosed is binding on a strata corporation in its dealings with a person who relies on the certificate. However, Form B is not revealing if a strata corporation has not taken any action to discover a serious problem, or to deal with known major problems.

In this study, five sales qualified to receive a Form B, but only three had. However, the certificate did not alert the buyers to any problems because the need for major repairs had not yet been detected.

Engineering reports

The term ‘engineering report’, when associated with condominiums in the coastal climate area, is assumed to be an investigation of the building envelope. The credibility attached to these reports is very high.

None of the contracts contained a request for an engineering report. However, in four cases, the buyers did receive information from engineering studies. In one case, the scope appears to have been limited, and the recommended repairs were a temporary measure, although this was not explicitly stated. In another case, a buyer received information extracted from an engineering report but not the entire report, which recommended a repair costing 400 per cent of what was suggested in the extract.

Even if an engineering report is obtained, a buyer may not have sufficient knowledge to understand it. While some reports are straightforward, some have technicalities that would be detected only by a knowledgeable reader.


Conclusions are made on the sample of problem transactions studied. No conclusions, extrapolations or generalizations can be made about the extent to which there are problems with the investigative tools in the re-sale marketplace.

All of the investigative tools have shortcomings, individually and collectively. In each instance investigated, a clear understanding of the risk was not apparent regardless of the tools used.

Even if the use of investigative tools is more frequent, or if the leaky condo crisis has peaked, it is clear that there will still be many condominium buyers who discover, after the fact, that "what they got is not what they thought they bought." The tools are flawed, the contract can fail to require all the necessary documentation, and there is little assistance for buyers in understanding and analyzing the information they receive.
