1. Who must comply — the three criteria
Singapore's Building Control (Periodic Facade Inspection) Regulations set out three conditions that trigger a mandatory PFI. Your building must meet all three:
Building type: The regulations apply to non-residential buildings and flatted factories. This includes shophouses used for commercial or mixed commercial-residential purposes, standalone commercial buildings, industrial buildings, and mixed-use developments. Purely residential HDB blocks and private condominiums are excluded from the PFI regime (they fall under a separate Facade Inspection Safety Programme).
Height: The building must be more than 13 metres tall. In practice this means roughly four storeys or above — the vast majority of Singapore shophouses in conservation districts fall within this threshold.
Age: The building must be at least 20 years old at the time of the first PFI notification. BCA maintains records of completion dates and issues notification letters when buildings reach the threshold age.
If you have received a BCA notification letter, the inspection deadline is stated within it. Do not ignore the letter — failure to comply can result in BCA enforcement action, including stop-work orders, penalties, and legal liability if facade failure causes injury or property damage.
Conservation status under URA does not exempt a building from the PFI regulations. If a shophouse meets all three criteria, it must be inspected regardless of its heritage listing. In fact, conservation buildings typically require more careful inspection due to the complexity of their original materials.
2. What the inspection covers
A PFI conducted by a BCA-registered Competent Person covers every accessible facade element — not just the most visible surfaces. The scope includes:
Render and plasterwork: The condition of all applied finishes — cement render, lime plaster, Shanghai plaster, pebble dash, and painted surfaces. Inspectors look for spalling (detachment of surface material), delamination (separation from substrate), hollow render detectable by tapping, active cracking, and efflorescence (salt deposits indicating water movement through the wall).
Structural masonry and concrete: The underlying brickwork, masonry, and any reinforced concrete elements. Cracking patterns are assessed to distinguish cosmetic shrinkage cracks from structural movement. Signs of reinforcement corrosion — rust staining, concrete spalling exposing steel — require urgent attention.
Windows, louvres, and frames: All openings in the facade. Failed sealants, corroded frames, inadequate fixings, and water ingress at window-to-wall junctions are common findings, particularly in buildings over 40 years old.
Balconies, cornices, and ornamental elements: Any projecting element is a potential falling hazard if deteriorated. Balcony soffits are frequently affected by water ingress; decorative cornices and plasterwork can delaminate in sections.
Waterproofing and drainage: Parapet copings, roof-to-wall junctions, downpipes, and drainage outlets. Ponding water, blocked outlets, and failed waterproofing membranes are a primary cause of progressive facade deterioration.
Attached fixtures: Air-conditioning condensers, signage brackets, pipe supports, and any other element fixed to the facade from outside. These are assessed for fixing adequacy, corrosion, and risk of detachment.
For taller buildings or facades with limited ladder access, inspectors use MEWPs (Mobile Elevated Work Platforms), rope access technicians, or aerial drones depending on the geometry and access constraints of the building.
3. What a PFI report contains
A compliant PFI report is a structured technical document, not a brief letter. BCA sets minimum requirements for its content. A properly prepared report will include:
Building particulars: Address, UEN, building use, year of completion, number of storeys, and facade area.
Inspector credentials: The BCA registration number, qualifications, and signature of the Competent Person who conducted the inspection.
Inspection methodology: The access methods used (ladder, MEWP, rope access, drone), the date(s) of inspection, and weather conditions.
Elevation drawings with defect mapping: Annotated drawings or photographs showing the location of every defect recorded, referenced to a consistent grid or elevation scheme.
Defect schedule: A tabulated list of all defects, each described, classified by severity, photographed, and accompanied by a remedial recommendation.
Inspector's certificate: A signed declaration that the building is safe for continued occupancy, subject to the rectification of any significant or critical defects within the specified timeframes.
The signed report is submitted directly to BCA by the Competent Person. Owners do not submit directly. BCA will acknowledge receipt and, if the report is accepted, issue a Compliance Certificate.
4. Defect severity — what it means for you
PFI reports classify defects into three severity categories. Understanding what each category means in practice helps owners plan their response appropriately.
| Severity | Typical Examples | Required Action | Timeframe |
|---|---|---|---|
| Minor | Surface hairline cracks, minor paint peeling, superficial efflorescence, minor rust staining | Monitor at next inspection. No immediate rectification required. | Next PFI cycle (7 years) |
| Significant | Hollow render over >0.5 sqm, moderate cracking with water ingress, corroded reinforcement, failed sealants with active leaks | Rectify and submit a Rectification Report to BCA confirming works completed. | Typically within 6–12 months as specified by inspector |
| Critical | Loose render or spalling concrete at height, structural cracking, imminent risk of material falling | Immediate temporary protection (netting, hoarding). Full Investigation required. Emergency works may be necessary. | Immediate — within days |
WK Facade does not carry out rectification works. This is a deliberate policy to avoid conflicts of interest — our only obligation is to give you an accurate picture of your building's condition. We will recommend suitable contractors for rectification, but we have no financial relationship with any of them.
5. Inspection frequency and timing
After the initial PFI is completed and accepted by BCA, subsequent inspections are required every 7 years. BCA will issue a new notification letter approximately 6 months before each inspection falls due.
We recommend engaging your inspector at least 3 months before the BCA deadline. This allows time to agree on access arrangements, coordinate with tenants or occupants, schedule the on-site inspection date, allow time for the report to be drafted and reviewed, and submit before the deadline with margin for any BCA queries.
Retaining the same inspector across cycles has a practical advantage: your inspector builds a defect history for the building, making it easier to identify progressive deterioration between inspections — not just new defects.
If you are acquiring a building, ask the vendor for the last PFI report and when the next inspection falls due. Significant defects already identified, or an inspection due within 12 months, should be reflected in your due diligence and purchase negotiations.
6. Conservation shophouses — what's different
Conservation shophouses are subject to the same PFI regulations as other qualifying buildings, but the inspection itself is more complex. Three factors set them apart.
Original materials behave differently. Pre-war shophouses were built with lime-based mortars and renders, not modern cement. Lime render is breathable — it allows moisture to move through the wall rather than becoming trapped. This means defects present differently: hollow lime render can look superficially intact while having lost adhesion over large areas. An inspector unfamiliar with lime systems may underestimate the extent of deterioration.
URA guidelines govern repair methods. Any rectification works to a URA-gazetted conservation building must comply with URA's conservation guidelines. This means like-for-like repair using compatible materials — you cannot simply patch lime render with cement mortar, as this causes long-term damage by trapping moisture. Your PFI report should acknowledge this context so that rectification contractors understand the constraints.
Access is often more challenging. Conservation shophouses in active commercial use — particularly those in Tanjong Pagar, Chinatown, and Kampong Glam — present access challenges. Five-footways must remain clear, neighbouring properties must be coordinated with, and drone access in conservation districts may require additional approvals. Experienced inspectors account for this in their planning and scheduling.

7. Cost of a facade inspection in Singapore
Facade inspection fees in Singapore vary based on several factors and are not publicly listed by most firms. The key variables that affect cost are:
Facade height and area: A two-storey shophouse facade requires significantly less access infrastructure than a six-storey commercial building. Taller buildings require MEWP hire, rope access teams, or drone deployment — all of which add to cost.
Access requirements: If the building facade is accessible by ladder from public footways, costs are lower. If access requires a MEWP, rope access technicians, or aerial drones, these are additional line items. For buildings with difficult access, a preliminary site visit is usually required before a fee can be quoted.
Facade complexity: A simple rendered facade with standard windows is straightforward to document. A heavily ornamented conservation shophouse with relief plasterwork, projecting cornices, timber louvres, and multiple facade planes requires significantly more time on site and in report preparation.
Whether a Full Investigation is required: If the initial inspection identifies defects requiring close-access investigation — for example, significant hollow render on an upper storey — a Full Investigation report may be required by BCA in addition to the standard PFI. This involves more detailed access and testing and is quoted separately.
WK Facade provides fixed-fee quotes after a brief site assessment. We do not bill by the hour, and our quote covers the inspection, all report preparation, and submission to BCA. Contact us for a quote specific to your property.
8. How to choose a BCA-registered inspector
Only a BCA-registered Competent Person (Facade Inspector) can conduct a PFI and sign the report submitted to BCA. Selecting the right inspector matters for two reasons: the quality of the report determines BCA acceptance, and the depth of the inspection determines whether genuine defects are found or missed.
The BCA maintains a public list of registered Competent Persons for facade inspection on its website. When evaluating inspectors, ask:
Is the inspector personally BCA-registered? Some firms quote via a registered inspector but conduct inspections using unregistered staff. The registered person must be the one who physically conducts the inspection and signs the report.
What is their experience with your building type? A conservation shophouse requires different expertise from a modern commercial building. Ask specifically about experience with the materials your building is made of.
What access methods do they use? An inspector who only uses binoculars from the street level cannot certify a facade adequately. Physical close-access inspection is required for higher facades.
Do they have a track record of first-submission BCA acceptance? Rejected reports cause delays and additional cost. A well-prepared report with correct format, adequate photographic evidence, and clearly classified defects should be accepted on first submission.
