If you're planning to install signage on a commercial building in Singapore, understanding BCA (Building and Construction Authority) approval requirements is critical. Getting it wrong can mean costly delays, rejected submissions, and wasted fabrication costs.
This guide walks you through exactly what BCA approval is, when it's required, what documents you need, and how to ensure your signage gets approved the first time.
In This Guide
What is BCA Approval?
The Building and Construction Authority (BCA) is Singapore's statutory board that regulates the building and construction industry. For signage, BCA approval ensures that any signs attached to buildings meet structural safety standards and do not compromise the building's integrity.
BCA approval is separate from:
- URA approval — Required for conservation areas and certain shopfront modifications
- Landlord/mall approval — Required by building owners or mall management
- Town Council approval — Required for HDB commercial spaces
Important: Most commercial signage projects require BOTH BCA approval AND landlord approval. Always check both requirements before starting.
When is BCA Approval Required?
BCA approval is required for permanent external signage that is structurally attached to buildings. Here's a breakdown:
Signage Types That REQUIRE BCA Approval
- Fascia signs (building-mounted shopfront signs)
- Projecting signs (blade signs perpendicular to building)
- Rooftop signs
- Building-mounted LED displays
- Large wall-mounted signage (depending on size and weight)
- Signage requiring structural support modifications
Signage Types That TYPICALLY DO NOT Require BCA Approval
- Internal office signage (within leased premises)
- Window vinyl decals (non-structural)
- Temporary banner stands
- Exhibition graphics and pop-up displays
- Free-standing signage not attached to buildings
Note: Even if BCA approval is not required, you still need landlord/mall approval for almost all commercial signage. Never skip this step.
The BCA Approval Process (7 Steps)
Here's the complete step-by-step process for obtaining BCA approval for signage:
Determine Approval Requirements
Confirm whether your signage type, location, and installation method require BCA approval. Check with your landlord or building management as they often have this information readily available.
Conduct Site Measurement
Accurate on-site measurements are critical. Measure the exact location, available mounting points, clearances from fire exits/sprinklers, and building facade details. Incorrect measurements are a leading cause of approval delays.
Prepare Technical Shop Drawings
Create detailed technical drawings showing:
- Sign dimensions and materials
- Installation method and mounting details
- Building elevation context
- Clearances from building features
- Electrical connections (if illuminated)
Obtain Structural Calculations & PE Certification
For projecting signs, large signs, or signs in high-wind areas, you'll need:
- Structural load calculations
- Wind load analysis
- Professional Engineer (PE) certification and stamp
This typically costs SGD 800-2,000 and adds 5-7 days to your timeline.
Secure Landlord Approval First
Most landlords require you to obtain their written approval BEFORE submitting to BCA. Submit your shop drawings to building management and wait for their approval letter. This can take 7-14 days depending on the landlord.
Submit to BCA via CORENET
Submit your complete application package through the CORENET system or building plan submission portal. Required submissions include:
- Completed BCA application forms
- Technical shop drawings (PDF format)
- Structural calculations and PE cert (if required)
- Landlord approval letter
- Submission fee payment
Respond to BCA Comments & Receive Approval
BCA will review your submission and may issue queries or request revisions. Respond promptly to avoid delays. Once approved, you'll receive written approval — only then should you start fabrication and installation.
Required Documents Checklist
To avoid delays, ensure you have ALL of these documents ready before submission:
Essential Documents (Always Required)
- Completed BCA application form with company stamp
- Detailed shop drawings showing dimensions and materials
- Elevation drawings with building context
- Installation method details and mounting specifications
- Landlord/building owner consent letter
- Proof of submission fee payment
Conditional Documents (Depending on Signage Type)
- Structural calculations (for projecting or large signs)
- PE certification and stamp (for structurally significant signs)
- Wind load analysis (for rooftop or projecting signs)
- Fire safety clearance confirmation (for signs near exits)
- Electrical wiring diagrams (for illuminated signage)
- URA approval (if in conservation area)
Timelines & Costs
Typical Timeline Breakdown
| Stage | Duration | Notes |
|---|---|---|
| Site measurement | 1-2 days | After scope confirmation |
| Shop drawing preparation | 3-7 days | Depends on complexity |
| PE certification (if needed) | 5-7 days | Requires structural calculations |
| Landlord approval | 7-14 days | Varies by building management |
| BCA review & approval | 7-14 days | If complete and compliant |
Total typical timeline: 3-6 weeks from measurement to BCA approval. Complex projects or incomplete submissions can take 8-12 weeks.
Cost Breakdown
| Item | Typical Cost (SGD) |
|---|---|
| Site measurement | $200 - $500 |
| Shop drawing preparation | $500 - $1,500 |
| PE certification (if required) | $800 - $2,000 |
| BCA submission fee | $150 - $500 |
| Total approval costs | $1,650 - $4,500 |
Note: These costs are separate from signage fabrication and installation costs.
Common Rejection Reasons (And How to Avoid Them)
Based on industry experience, here are the most common reasons BCA rejects signage submissions:
1. Incomplete or Inaccurate Drawings
Why it happens: Drawings missing critical details like material specifications, exact dimensions, or installation method.
How to avoid: Use professional draftspersons experienced with BCA submissions. Include ALL dimensions, materials, mounting details, and clearances.
2. Missing Structural Calculations
Why it happens: Projecting signs or large wall signs submitted without structural analysis.
How to avoid: For any projecting sign or sign larger than 2m², engage a PE to provide structural calculations upfront.
3. Fire Safety Clearance Issues
Why it happens: Signs blocking fire escape routes, too close to sprinklers, or obstructing fire safety signage.
How to avoid: Ensure minimum clearances from all fire safety features during site measurement. Highlight these clearances in drawings.
4. Insufficient Installation Details
Why it happens: Generic "to be installed" notes without specific mounting method, fixing types, or load distribution.
How to avoid: Specify exact fixing method (chemical anchors, expansion bolts, etc.), spacing, and load calculations.
5. Signs Exceeding Approved Dimensions
Why it happens: Submitted dimensions don't match earlier landlord approvals or violate building regulations.
How to avoid: Cross-check dimensions with landlord approval before BCA submission. Ensure consistency across all documents.
6. Missing PE Certification
Why it happens: Structurally significant signs submitted without required PE stamp.
How to avoid: Clarify PE requirements early. If in doubt, engage a PE — it's cheaper than resubmission delays.
Tips for First-Time Approval Success
Start with Landlord Requirements
Always obtain landlord approval FIRST. Their guidelines often exceed BCA minimums and will inform your BCA submission.
Hire Experienced Professionals
Working with signage companies that handle drawings, submissions, and compliance saves time and prevents costly mistakes.
Measure Twice, Submit Once
Accurate site measurements are non-negotiable. Incorrect measurements cause approval rejections and fabrication rework.
Allow Sufficient Lead Time
Budget 4-6 weeks for approvals. Rushing submissions with incomplete documents always causes longer delays.
Don't Start Fabrication Early
Never fabricate signage before receiving written BCA approval. Changes during approval can make pre-fabricated signs unusable.
Keep Communication Records
Save all landlord approvals, BCA queries, and revision requests. These create a clear audit trail if issues arise.
Frequently Asked Questions
Can I install signage before BCA approval?
No. Installing signage before receiving BCA approval is illegal and can result in:
- Enforcement action and fines
- Mandatory removal of installed signage
- Future submission difficulties
Always wait for written approval before installation.
What if my BCA submission is rejected?
BCA will issue comments explaining rejection reasons. You can revise and resubmit, but this adds 2-4 weeks to your timeline. Address ALL comments completely in your resubmission.
Do I need separate URA approval?
URA approval is required if your building is in a conservation area or if signage affects the building's facade in heritage zones. Check with URA or your landlord. URA approval must be obtained BEFORE BCA submission.
Can I submit BCA approval myself?
Technically yes, but it's not recommended unless you have experience with technical drawings and BCA requirements. Most building owners require professional submissions and PE certification anyway.
How long is BCA approval valid?
BCA approval is typically valid for 12 months from the approval date. If installation is not completed within this period, you may need to resubmit or request an extension.
What happens after installation?
After installation, some buildings require a completion certificate or as-built documentation to be submitted to the landlord. Check your landlord's requirements.
