Defects Liability Notice (Hong Kong)

A Defects Liability Notice in Hong Kong gives formal notice of the matter it concerns to the recipient.

The defects liability period in Hong Kong is a contractual provision, not a statutory right. Standard Hong Kong construction contracts set the DLP at 12 months from the date of practical completion of the works, as certified by the architect under the HKIA Standard Form or by the engineer or supervising officer under the Government General Conditions of Contract. During the DLP, the contractor must return to site at their own cost to rectify any defects — defined as work that does not conform to the contract drawings, specifications, or workmanship standards — that are notified by the employer or contract administrator.

The Buildings Ordinance (Cap. 123) and its subsidiary regulations govern the standards to which buildings in Hong Kong must be constructed, and defects that breach statutory standards may also engage the liability of the Authorized Person (registered architect, engineer, or surveyor) appointed under Cap. 123 who supervised the works. The Buildings Department has enforcement powers to issue repair orders under Cap. 123 independently of the contractual DLP mechanism.

The Limitation Ordinance (Cap. 347) governs the time limits for bringing claims against contractors for defective work. Section 4 of Cap. 347 provides a 12-year limitation period for claims under deeds and a 6-year period for claims under simple contracts. Section 31 imposes a 15-year long-stop for negligence claims. A Defects Liability Notice issued during the DLP preserves the employer’s right to claim for those specific defects and creates a clear record of when the defect was first identified, which is relevant to limitation period calculations for latent defects discovered after the DLP expires.

All contract sums and rectification costs are in HKD. Hong Kong imposes no GST or VAT on construction services, simplifying the financial accounting of defects rectification costs.

The Hong Kong Institute of Architects (HKIA) Standard Form of Building Contract (2005 Edition and Minor Works Edition) is the most widely used standard form contract for private sector building works in Hong Kong. Clause 17 of the HKIA Standard Form provides the standard defects liability mechanism: the architect issues a Schedule of Defects to the contractor within 14 days after the expiry of the defects liability period, and the contractor must rectify the listed defects within a reasonable time specified by the architect. The Government of the HKSAR General Conditions of Contract for Building Works (GCC) contains equivalent provisions for public sector projects administered by the Architectural Services Department, the Civil Engineering and Development Department, and the Drainage Services Department. The Construction Industry Council (CIC) publishes guidelines on defects liability practices and dispute resolution in Hong Kong construction, which provide useful context for employers and contractors navigating defects claims. All contract amounts and costs related to defects rectification under a Hong Kong construction contract are denominated in HKD; Hong Kong imposes no GST or VAT on construction services.

A Defects Liability Notice in Hong Kong is needed whenever defects are discovered in construction works during the contractual defects liability period, and the employer or contract administrator wishes to formally notify the contractor of those defects and require rectification at the contractor’s cost.

When visible cracks appear in the walls, floors, or ceilings of a newly completed residential or commercial building in Hong Kong within 12 months of the architect’s Certificate of Practical Completion, the employer should issue a Defects Liability Notice to the contractor promptly. Delay in giving notice may prejudice the employer’s position and give the contractor grounds to argue that they were not given a reasonable opportunity to inspect and rectify.

When waterproofing systems in flat roofs, podiums, or wet areas of a newly completed Hong Kong building fail within the DLP — a common construction defect given Hong Kong’s subtropical climate and heavy monsoon rainfall — the employer or architect must issue a Defects Liability Notice specifying each affected location, the nature of the failure, and the rectification period.

When mechanical and electrical (M&E) installations — air conditioning systems, ventilation plant, electrical distribution boards, fire suppression systems, or lifts — malfunction or fail to perform to specification within the DLP, the employer should issue a Defects Liability Notice to the M&E contractor or, if they have a separate M&E subcontract, to the main contractor who is responsible for all subcontractors’ work.

When external finishes — curtain walling, cladding panels, tiling, or paintwork — fail to meet the contract specification or begin to deteriorate within the DLP, the employer or architect should issue a Defects Liability Notice identifying each area of non-conforming finish and setting a reasonable rectification period.

When an Authorized Person under the Buildings Ordinance (Cap. 123) or the Buildings Department identifies non-compliant construction during the DLP, the employer may need to issue a Defects Liability Notice in addition to complying with any statutory repair order, to preserve their contractual right to require the contractor to carry out and bear the cost of rectification works.

When approaching the end of the DLP, the architect typically prepares a final schedule of defects and issues it as a Defects Liability Notice to give the contractor a last opportunity to rectify outstanding items before the DLP expires and the Defects Rectification Certificate is issued, triggering release of the final half of the retention monies held by the employer.

A Defects Liability Notice in Hong Kong issued under a construction contract governed by the HKIA Standard Form, the Government General Conditions of Contract, or a bespoke form must include the following key elements to be contractually effective and to preserve the employer’s rights against the contractor.

Project and contract identification: The full project name, site address, Government Lease Lot number or Government Land Reference, the contract title and reference number, the name of the contractor, and the name of the architect or contract administrator issuing the notice on the employer’s behalf. Where the notice is issued by the employer directly (rather than through the architect), this should be made clear. The date of practical completion and the DLP commencement and expiry dates should be stated to confirm that the notice is being issued within the contractual DLP.

Defect schedule: A numbered schedule describing each defect in specific, clear terms. Each entry should state: the location within the building or site (floor level, grid reference, room number, or other precise identifier); the nature of the defect (for example, a horizontal crack in the blockwork above window lintel at Level 3, or leaking at the expansion joint in the podium waterproofing); the relevant contract drawing or specification reference that the work fails to comply with; and, where available, photographic evidence referenced to each schedule item. Vague or generalised defect descriptions weaken the notice and may give the contractor grounds to argue that they could not identify or access the defect.

Contract clause reference: The specific clause of the construction contract under which the notice is issued — for example, Clause 17 of the HKIA Standard Form of Building Contract (Minor Works Edition), or the equivalent clause in the Government GCC. Citing the contractual basis for the notice confirms that it is a formal contractual communication, not merely an informal complaint.

Rectification deadline: A stated deadline by which the contractor must complete all rectification works, typically 14 to 28 days from the date of the notice for straightforward defects. For complex structural or waterproofing defects requiring investigation and specialist work, a longer period of 28 to 42 days may be appropriate. The deadline must be reasonable in all the circumstances; an unreasonably short deadline may be unenforceable.

Access arrangements: Confirmation that the employer will provide reasonable access to the site and to affected areas for the contractor and their subcontractors and suppliers to carry out inspection and rectification. For occupied buildings, access arrangements must accommodate the needs of occupiers while permitting effective rectification.

Consequences of non-compliance: A clear statement that if the contractor fails to commence or complete rectification within the specified period, the employer reserves the right to engage other contractors to carry out the rectification works and to recover all costs incurred from the contractor, including by deduction from the retention fund held under the contract. Reference to the Limitation Ordinance (Cap. 347) and the employer’s right to claim damages for breach of contract reinforces the seriousness of the notice.

Delivery and record: The notice should be delivered in accordance with the notice provisions of the construction contract — typically by hand with written acknowledgement of receipt, by registered post, or by email to the contractor’s designated contract email address. A copy should be retained in the project file.
