Cladding compliance in Singapore rests on three layers: fire-safety rules from SCDF that govern which materials may be used and how they are traced, structural and performance standards that govern design and installation, and BCA’s Periodic Façade Inspection (PFI) regime that governs the building once it is occupied. Developers, Qualified Persons (QPs) and building owners each carry a defined part, and gaps usually appear in documentation rather than in intent.
This article sets out the rules in the order a project meets them: design, material approval, installation, and long-term inspection.
TL;DR
- External walls of buildings taller than 15 m, or within 1 m of a relevant boundary, must be built wholly of non-combustible materials under the SCDF Fire Code 2023, excluding compliant finishes.
- Composite cladding panels must be non-combustible or certified Class ‘0’, with a Certificate of Conformity (CoC) and traceable product information embossed on each panel.
- Buildings over 20 years old and more than 13 m tall need a façade inspection by a Competent Person every seven years, with defects repaired promptly.
- Design for Safety duties apply to projects with a contract sum of S$10 million or more, and a separate QP may be appointed for specialist façade systems.
- Continuing compliance depends on records: CoCs, test results, inspection reports and repair documentation.

The three layers of cladding compliance
Cladding is both a building envelope element and a fire-safety element. Singapore therefore does not regulate it through a single rule. A façade system can pass one layer and fail another, so each is treated separately below.
| Layer | Main concern | Who is accountable | Typical evidence |
|---|---|---|---|
| Fire safety (SCDF) | Combustibility, spread of fire over external walls | Developer, QP, Registered Inspector | CoC, material test results, embossed panel data |
| Design and performance | Structural adequacy, water-tightness, air permeability | QP (Design), specialist engineer | Calculations, drawings, performance tests |
| In-service condition (BCA) | Deterioration, falling-object risk | Building owner, Competent Person | PFI report, repair records |
Fire-safety rules for external walls and cladding
Non-combustibility and the 15 m and 1 m triggers
Under Clause 3.5 of the Fire Code, external walls of buildings exceeding 15 m in height, or situated within 1 m of a relevant boundary, must be constructed wholly of non-combustible materials, excluding finishes that comply with the Code (SCDF Fire Code 2023, Clause 3.5). These two triggers should be checked at the schematic stage, because they decide whether a lighter, cheaper cladding option is available at all.
A practical consequence is that a boundary condition can bring a low building into the same rule as a tower. A three-storey industrial block built close to its site boundary may face the same material restrictions as a much taller building.
Our separate guide to cladding fire compliance under Fire Code 2023 covers the clause logic in more detail.
Composite panels, CoCs and embossing
SCDF’s advisory on external wall finishes states that composite panels used as cladding must be non-combustible or certified as Class ‘0’ and must have a CoC. It also sets out that critical information, including brand, model, fire performance, manufacture date and CoC reference, is to be permanently embossed on each panel (SCDF circular on external wall finishes).
The same advisory states that SCDF intends to make it mandatory for QPs to submit the CoCs of composite panels as part of the building plan submission. QPs are expected to supervise testing of panels taken from project sites, to confirm the scale of usage and where the panels are installed, and Registered Inspectors verify that these requirements have been fulfilled.
The embossing requirement is what makes a panel traceable years after installation. A panel without legible markings is difficult to defend in an inspection, even if the original delivery was genuine.
Why certificate integrity matters
Certification has been enforced through prosecution. A manager was convicted in a case involving cladding sold without fire safety approval, reported by CNA. That report also notes that, at the time, each CoC was valid for three years and panels were subject to annual surveillance fire tests. Validity terms can change, so the current requirements should be confirmed with SCDF at the point of procurement.
For project teams, the lesson is procedural: obtain the CoC before ordering, match the CoC reference to the panel markings on delivery, and file the match in the project record.
Design and performance standards for cladding systems
For metal-framed curtain walls, Singapore Standard SS 654:2020 specifies materials and performance standards and gives requirements for good practice in design and installation. Its performance tests cover air permeability, water-tightness and structural performance.
A compliant specification normally addresses the following:
- Structural adequacy: wind loads, anchorage to the primary structure, movement and tolerances.
- Weather performance: water-tightness and air permeability demonstrated through testing.
- Fire performance: material classification and the Fire Code triggers above.
- Maintainability: access for cleaning, inspection and replacement of panels and sealants.
- Safe installation: temporary works, lifting and edge protection during installation.
Points one and five are where engineering input matters most. Anchorage failures and installation accidents typically trace back to details that were never coordinated between the façade supplier and the structural designer. Our façade design service addresses this coordination from the design stage.
Design for Safety duties on cladding projects
The Workplace Safety and Health (Design for Safety) Regulations apply to projects with a contract sum of S$10 million or more and to all developments under the Planning Act. Developers must hold review meetings with stakeholders and maintain a DfS Register recording identified design risks and mitigation measures (WSH (Design for Safety) Regulations 2015).
For cladding, typical DfS entries include:
- Heavy panels and the lifting method required at height.
- Fixings that must be installed from outside the building line.
- Cleaning and maintenance access for future inspections.
- Replacement of damaged panels without scaffolding the whole elevation.
A risk logged at design stage costs far less than one found when a panel is half installed. More detail is available in our overview of Design for Safety in engineering in Singapore.
Qualified Person and Professional Engineer roles
Who is responsible for what
A BCA clarification circular, published through ACES, states that a separate QP (Design) may be appointed for cladding or façade works only where the main QP for the superstructure is unfamiliar with the structural system used for the cladding, meaning that QP has not undertaken similar façade systems in a previous or ongoing project. The main QP(D) is to advise the developer to appoint the appropriate QP(D)s and ensure that design and construction are properly coordinated (BCA clarification circular).
In plain terms, the default is a single coordinating QP. A specialist is brought in when the façade system is outside that QP’s experience. Developers should record that decision early, together with the reasoning.
For public housing, the Parliament of Singapore record notes that claddings and fixtures in HDB flats are usually designed and supervised by a Specialist QP who is a Professional Engineer, with plans approved by BCA (Parliament debate, 6 August 2018).
Where a Professional Engineer comes in
A Professional Engineer is typically engaged to endorse structural and geotechnical aspects of façade support, to endorse temporary works used during installation, and to act as Competent Person for periodic façade inspection of existing buildings. The Competent Person under the PFI regime must be a Professional Engineer or Registered Architect (BCA). For the formal scope of any specific appointment, the project’s QP and the authority’s current requirements govern.
Periodic Façade Inspection for existing buildings
Which buildings are covered
BCA announced that façade inspections are required every seven years for buildings more than 13 m tall once they are over 20 years old, with landed houses and temporary buildings exempted (BCA newsroom, 21 October 2021). The regime takes effect under the Building Control (Periodic Inspection of Buildings and Building Façades) Regulations 2021, in force from 1 January 2022 and amended on 1 October 2025.
BCA explained that the 20-year threshold reflects the typical lifespan of common building materials, and the 13 m threshold reflects the greater risk from taller buildings (BCA, 18 May 2020).
What owners must do
Owners must appoint a Competent Person, who may be assisted by a Façade Inspector, and must repair detected defects promptly (BCA PFI page). Both Competent Persons and Façade Inspectors must complete a BCA-approved Certificate of Façade Inspection course. The Competent Person conducts a full visual inspection and a representative hands-on inspection of each elevation, and may use drones, borescopes and scanning equipment.
Independence rules for inspectors
Under Regulation 16A, a competent person must not appoint a façade inspector who is a partner, officer or employee of the building owner, the builder, any person involved in building works on the façade, or an associate of any of them. Under Regulation 16B, inspectors must carry out visual or close-range inspections with reasonable diligence, personally supervise anyone operating inspection equipment, and immediately notify the competent person in writing of any suspected sign of collapse risk (BCA circular on façade inspector regulations).
Owners who plan the inspection cycle should read our guide to façade testing requirements and the seven-year PFI cycle.
Records that demonstrate continuing compliance
The regulations above do not stand alone; each produces a document. A defensible cladding file typically holds:
- Material approvals: CoCs for each panel type, with references that match embossed panel markings.
- Test records: results from sampled panels where the QP supervised testing.
- Design records: calculations, drawings, DfS Register and the record of any specialist QP appointment.
- Installation records: shop drawings, as-built changes and the temporary works design.
- Inspection reports: each PFI report, the date of the next due inspection and the Competent Person’s details.
- Remedial records: defects found, repair method, who carried it out and the closing inspection.
A useful habit is a single register that links each elevation to the panel type, its CoC and its latest inspection. When a building changes hands or is refurbished, this register shortens due diligence considerably. The construction compliance checklist offers a broader project-level view.
Common failure points
- Panels delivered with a CoC that does not match the markings on the panels.
- Boundary conditions overlooked, so the 1 m trigger is discovered after material selection.
- Façade supplier and structural designer working without a coordinated anchorage design.
- PFI due dates tracked by an outgoing property manager and lost at handover.
- Defects noted in a report but not closed out with repair evidence.
Our perspective
Cladding problems in Singapore are rarely caused by a missing rule. They come from a missing handover between the people who specify the façade, the people who install it and the people who own it years later.
Our approach is to treat the cladding file as a deliverable from day one. We prepare the structural and façade design, coordinate PE endorsement and temporary works, and manage submissions to the relevant authorities, so that the CoCs, calculations and drawings agree with one another when the authority or an inspector asks for them.
For existing buildings, we support BCA Periodic Façade Inspection and the repair consultancy that follows, so that findings lead to documented closure rather than a report that sits in a drawer. We aim to give clear, direct communication and timely turnaround, because cladding decisions are usually on the critical path.

For projects with a fire-safety submission, our SCDF fire safety compliance guide explains how submissions are prepared and what QPs should have ready.
FAQ
Does every cladding system need to be non-combustible?
Not every one. The non-combustibility requirement applies to external walls of buildings over 15 m in height or within 1 m of a relevant boundary, excluding compliant finishes. Composite panels used as cladding must be non-combustible or certified Class ‘0’ with a CoC. The QP should confirm which condition applies to the specific building.
How often must a building’s façade be inspected?
Every seven years, once the building is over 20 years old and more than 13 m tall. A Professional Engineer or Registered Architect with the required façade inspection certificate acts as Competent Person. Landed houses and temporary buildings are exempt.
Can the owner’s own staff carry out the façade inspection?
No, not as façade inspectors. Regulation 16A bars a competent person from appointing an inspector who is a partner, officer or employee of the building owner, or of the builder or others involved in the façade works, or their associates. Owners should engage an independent inspection team.
Is a separate QP needed for cladding?
Only in specific cases. Under BCA’s clarification, a separate QP(Design) may be appointed for cladding when the main QP is unfamiliar with the structural system used. Otherwise the main QP coordinates the design.
Do Design for Safety rules apply to cladding?
Yes, where the project falls under the regulations, meaning a contract sum of S$10 million or more or a development under the Planning Act. Cladding hazards such as heavy lifts and edge work are recorded in the DfS Register along with their mitigation.
