All About Property | Construction disputes and prescription: When does a debt arising from a builder’s breach of a warranty to repair structural defects become due?

In an important ruling in the context of construction disputes, the Supreme Court of Appeal (‘the SCA’) recently considered when a debt arising from a home builder’s breach of the statutory warranty to repair major structural defects becomes ‘due’ for purposes of section 12(3) of the Prescription Act. Critically, the Court held that a debt does not become due merely because structural defects are discovered. Rather, the prescription clocks starts ticking only once the builder has failed or refused to honour its warranty after being afforded a reasonable opportunity to do so.

The factual background

In Janse van Vuuren v WJB Stieger Konstruksie (Pty) Ltd, a homeowner contracted with the builder to construct a residential home in accordance with the National Home Builders Registration Council (‘NHBRC’) Technical Requirements. Importantly, the parties’ agreement incorporated the warranties contained in sections 13(2)(a) and 13(2)(b)(i) of the Housing Consumers Protection Measures Act. Critically, this included the builder’s obligation, at its own cost and upon demand, to rectify major structural defects caused by non-compliance with the NHBRC Technical Requirements, provided the defects occurred and were reported within five years of occupation.

After taking occupation in October 2016, the homeowner observed cracking and subsidence in the house. The builder initially carried out remedial work and later appointed a structural engineer to investigate further defects. Following an inspection, the engineer’s report confirmed major structural defects, identified the remedial work required, and found that the house was uninhabitable. The homeowner demanded that the defects be repaired, and the builder continued attempting remedial work during 2018, although such efforts ultimately proved ineffective. In January 2021, the homeowner instituted a damages claim for the cost of repairing the defects and related losses.

The builder raised a special plea of prescription, contending that the claim had prescribed because the homeowner knew of the structural defects more than three years before the action was instituted. According to this argument, the homeowner became aware of the major structural defects in December 2017 and was thus required to institute proceedings in December 2020 to prevent his claim from prescribing. The trial court dismissed the special plea, but a full bench of the High Court upheld it. The SCA was accordingly required to adjudicate when the debt became due under section 12(3) of the Prescription Act.

Knowledge of defects is not knowledge of a breach

On appeal, the central issue for determination was whether knowledge of structural defects is sufficient to render the debt due. The SCA held that it is not.

Under section 12(3) of the Prescription Act, a debt is not deemed to be due until the creditor has knowledge of the identity of the debtor and the facts from which the debt arises. In interpreting this proviso, the Court reaffirmed that prescription begins to run only when the creditor has the minimum facts necessary to institute legal proceedings and is in a position to enforce that right in law.

Crucially, the SCA distinguished between knowledge of defects and knowledge that the builder has breached its warranty. Discovering structural defects merely enables the homeowner to notify the builder and invoke the statutory warranty. It does not, however, mean that the builder has already breached its obligation. To that end, a damages claim arises only once the builder has failed or refused to carry out the required repairs at its own cost after being afforded a reasonable opportunity to do so.

When does the debt become due?

Section 13(2)(b)(i) of the Housing Consumers Protection Measures Act obliges the builder, upon notification, to rectify qualifying major structural defects at its own cost and within a reasonable time. Although this provision does not prescribe a specific period for completing repairs, it necessarily offers the builder a reasonable chance to comply before any breach occurs.

It follows that the minimum facts necessary before a debt for damages becomes due are:

  • The existence of major structural defects;
  • That those defects were caused by non-compliance with the NHBRC Technical Requirements; and
  • That the builder has failed or refused to repair those defects at its own cost after receiving a reasonable opportunity to do so.

According to the Court, only once these perquisites have been established is the housing consumer in a position to enforce a claim for damages based on the builder’s breach of the statutory warranty.

Why the full bench of the High Court erred

On an evaluation of the evidence, the SCA held that the court a quo conflated two distinct issues: Knowledge of structural defects and knowledge that the warranty had been breached. The former activates the builder’s obligation to repair while the latter gives rise to an enforceable claim for damages. By treating awareness of the defects as sufficient to commence prescription, the High Court failed to distinguish between these separate stages.

The SCA also rejected the court a quo’s reliance on section 16 of the Prescription Act. Section 13(2)(b)(i) of the Housing Consumers Protection Measures Act does not prescribe a time limit within which legal proceedings must be instituted. Instead, it defines the period during which the builder warrants against major structural defects. Correspondingly, it does not displace the ordinary operation of the Prescription Act.

An application of the principles to the facts

Applying the aforementioned principles to the facts of the case, the SCA found that the builder continued attempting repairs throughout 2018 and never communicated a refusal to repair the defects. Indeed, the engineer’s report identifying the defects and the necessary remedial work was only produced in January 2018, and the builder continued to undertake remedial work thereafter.

The Court observed that the homeowner acquired the minimum facts necessary to sustain his cause of action on 5th October 2018, when it became apparent that, although the builder was still attempting repairs, those efforts were ineffective. In any event, the builder failed to discharge the onus of proving that the homeowner had acquired the requisite knowledge more than three years before summons was served. The claim had therefore not prescribed and the appeal was upheld.

Key lesson

The decision confirms that, where a damages claim is founded on a home builder’s breach of the statutory warranty to repair major structural defects, prescription does not begin simply because the defects become apparent. Rather, it commences only once the builder has failed or refused to carry out repairs at its own cost within a reasonable time after being afforded the opportunity to do so. Until then, the homeowner does not possess the complete cause of action required for the debt to become due under section 12(3) of the Prescription Act.
