CAAS Drone Regulations Overview
The Civil Aviation Authority of Singapore (CAAS) regulates all unmanned aircraft operations under the Unmanned Aircraft (Public Safety and Security) Act 2015 and the Air Navigation Order. These regulations apply to every commercial drone operation including building inspections, facade surveys, and industrial asset inspections.
For building owners commissioning drone inspections, understanding these regulations matters for two reasons. First, hiring an unlicensed operator exposes you to legal liability. Second, inspection data collected without proper permits may not be accepted by BCA for compliance submissions.
CAAS regulations cover three areas: operator licensing, aircraft registration, and operational permits. Every commercial drone inspection must satisfy all three before any flight takes place.
Key Regulatory Requirements
Unmanned Aircraft Pilot Licence
All commercial drone pilots must hold a valid UAPL. The licence requires theoretical exams and practical flight assessments covering various operation types.
Drone Registration
Every commercial drone must be registered with CAAS with specifications, serial numbers, and owner information. Each receives a unique identification number.
Activity Permit
Each operation requires a permit specifying location, date, time, altitude, and purpose. Applications include risk assessments and emergency procedures.
Operator Certificate
Commercial providers may need an Operator Certificate demonstrating organisational capability, safety management, and trained personnel.
Airspace Rules and No-Fly Zones
Singapore's compact geography and proximity to Changi Airport, Seletar Airport, Paya Lebar Air Base, and Tengah Air Base means airspace management is strict.
| Zone Type | Restriction | Inspection Impact |
|---|---|---|
| Airport Protection Zone | 5km radius — no flights without ATC clearance | Additional coordination required |
| Military Protected Area | Prohibited airspace | Alternative methods needed |
| Restricted Area | Specific altitude and time restrictions | Timing adjustments |
| General Airspace | Max 200ft AGL with activity permit | Standard operations |
We handle all airspace coordination. Whether your building is near Changi, in the CBD, or in Jurong, we obtain necessary clearances. Building owners do not need to apply separately.
Commercial vs Recreational Rules
| Requirement | Commercial (Inspections) | Recreational |
|---|---|---|
| Pilot licence | UAPL required | Not required (under 7kg) |
| Activity permit | Required per operation | Required outside approved areas |
| Insurance | Third-party liability required | Recommended |
| Registration | Mandatory | Mandatory (all drones) |
| Altitude | Per permit (up to 200ft) | Max 200ft in approved areas |
How to Verify CAAS Compliance
- Ask for UAPL Number — every licensed pilot has a unique licence number. Request and verify it.
- Check Drone Registration — the drone should have a valid CAAS registration number displayed.
- Request Activity Permit — the operator should show the approved permit before flying.
- Verify Insurance — ask for the liability insurance certificate covering the operation.
- Review Safety Procedures — compliant operators have documented risk assessments and emergency procedures.
Frequently Asked Questions
What CAAS Rules Mean for a Building Owner Hiring a Drone Operator
Most building owners never apply for a drone permit themselves, but CAAS rules still affect them, because a facade survey flown without the right approvals can delay a compliance deadline or expose the owner to liability. Under current CAAS rules, any business flight outdoors needs an Unmanned Aircraft Operator Permit held by the organisation and an Activity Permit for the specific operation, regardless of the drone's weight. Each pilot flying for business must hold an Unmanned Aircraft Pilot Licence.
Location matters as much as paperwork. Sites within 5 km of an aerodrome, or inside restricted and protected areas, receive a stricter assessment and may face extra conditions on height, timing or equipment. Owners can check a site's status on the government's OneMap drone query tool before shortlisting providers.
When comparing quotes, it is reasonable to ask a provider to show its operator permit, explain how it will obtain the activity permit for your address, and confirm who the licensed pilots will be. For PFI work, BCA adds its own layer on top of CAAS: the Competent Person must notify BCA and attend the flights. Our drone PFI page explains how the two sets of rules fit together.
