What Is a CAAS Activity Permit?
A CAAS activity permit is the operational authorisation for every commercial drone flight in Singapore. Unlike the UAPL (which licenses the pilot) or registration (which identifies the aircraft), the activity permit authorises a specific operation at a specific location on specific dates.
Each inspection project requires its own permit. The application includes flight plans, risk assessments, and operator credentials that CAAS reviews before granting authorisation.
Building owners do not apply — we handle all CAAS authorisations. The permit cost and effort are included in our service.
Application Components
Flight Plan
Operational plan with flight area boundaries, altitude limits, patterns, takeoff/landing zones, and duration. Maps and coordinates mandatory.
Risk Assessment
Hazard identification including proximity to buildings, people, vehicles, aircraft. Each risk paired with mitigation and emergency procedures.
Operator Credentials
Pilot UAPL, drone registration, operator certificate, and evidence of training for the planned operation type.
Insurance Documentation
Proof of third-party liability insurance valid for operation dates with adequate coverage for the environment.
Processing Timeline
| Stage | Duration | Activity |
|---|---|---|
| Preparation | 2-3 days | Site assessment, flight planning, risk assessment |
| Submission | 1 day | Complete package submitted to CAAS |
| CAAS Review | 10-20 working days | Assessment, airspace coordination, approval |
| Issuance | 1-2 days | Permit with conditions issued |
Total lead time is typically 3-4 weeks. Contact us at least 4 weeks before your desired date, especially for locations needing additional airspace coordination.
Airspace Considerations
- Changi Airport Zone — within 5km requires ATC coordination. We operate here regularly.
- Seletar Airspace — northern locations need specific altitude and timing coordination.
- Paya Lebar Air Base — eastern locations require additional clearance. Usually restricted to specific hours.
- CBD High-Rise — tall buildings may require helicopter route coordination.
- Jurong Island — requires both CAAS permits and JTC security clearances.
- Sentosa — specific restrictions near integrated resort. Alternative scheduling resolves access.
After Permit Approval
Review Conditions
All conditions reviewed — area, altitude, timing, special requirements. Flight plan adjusted if needed.
Schedule Inspection
Coordinate with building management within permit validity. Weather contingency dates planned.
Pre-Flight Briefing
Team reviews conditions, safety procedures, communications. Building management briefed on what to expect.
Execute and Document
Flight conducted within conditions. Logs, times, and deviations documented. Compliance record filed.
Frequently Asked Questions
Singapore Context — Why This Matters
Singapore's built environment presents unique challenges for building inspection. With over 14,000 buildings subject to periodic facade inspection requirements, the scale of compliance activity is significant. The tropical climate — UV index consistently above 10, humidity averaging 80 percent, heavy monsoon rainfall, and constant thermal cycling from air conditioning — accelerates facade deterioration faster than in temperate climates.
The combination of ageing building stock and aggressive environmental conditions means facade defects develop faster and can progress to safety-critical levels more quickly than building owners expect. Tiles that might last 30 years in a temperate European climate may begin delaminating within 15-20 years in Singapore. Sealants rated for 20-year service life may fail in 10-12 years under constant UV bombardment.
This is why Singapore's regulatory framework mandates periodic inspections and why the quality of those inspections matters. A thorough drone inspection that identifies early-stage delamination allows preventive maintenance at a fraction of the cost of emergency repairs after tiles have fallen. Thermal imaging that detects moisture infiltration behind cladding prevents the progressive structural damage that unchecked water ingress causes over years.
For building owners and MCSTs, investing in quality inspection data from CAAS-licensed drone operators is not just about regulatory compliance — it is about protecting asset value, ensuring occupant safety, and managing long-term maintenance costs effectively. The buildings that are well-maintained and well-documented command higher market values and lower insurance premiums than those with incomplete inspection histories.
