Drone Cleaning Permits in Singapore
What the law actually requires, what it means for your project timeline, and how to check whether a contractor is operating legally.
Commercial drone cleaning is legal in Singapore, with permits. A contractor needs a CAAS Operator Permit for the business, an Activity Permit for each specific job filed at least one month ahead, and a valid Unmanned Aircraft Pilot Licence for each pilot. Sites near aerodromes need extra airspace assessment; restricted estates need separate clearance.
Key takeaways
- Three requirements: Operator Permit, per-job Activity Permit, and pilot licensing.
- One month minimum for activity permit applications - plan 3-4 weeks from acceptance.
- Check airspace yourself at OneMap before you even request quotes.
- Aerodrome proximity (Changi, Seletar, Paya Lebar) tightens assessment.
- Jurong Island needs JTC clearance on top - budget 6-8 weeks.

What the law requires
Drone operations in Singapore are regulated by the Civil Aviation Authority of Singapore. Any drone flown for business purposes — including cleaning — falls under commercial operation rules regardless of the aircraft's weight.
| Requirement | Who holds it | Notes |
|---|---|---|
| Operator Permit | The company | Covers the business as an operating entity |
| Activity Permit | Per job | Site-specific; apply at least 1 month ahead |
| Unmanned Aircraft Pilot Licence | Each pilot | Required for any commercial operation |
| Airspace assessment | Per site | Stricter near aerodromes |
| JTC clearance | Restricted estates | Jurong Island and similar |
Block activity permits are available for repeated operations at the same site, which is why recurring cleaning contracts carry lower permit overhead per visit than a series of one-off jobs.
Airspace restrictions
Singapore is small and densely served by aviation, so a large share of the island sits under some form of airspace constraint. The authoritative public source is OneMap's drone query service, where entering an address shows the restrictions applying at that location.
- Aerodrome proximity — sites near Changi, Seletar or Paya Lebar face stricter assessment and may carry altitude limits that change how a facade is worked
- Protected areas — military and security-sensitive sites where operations may be refused outright
- Restricted estates — Jurong Island and similar require estate-level clearance in addition to CAAS approval
Run this check before requesting quotes. It takes a minute and tells you whether drone cleaning is viable for your building at all. A contractor who quotes without mentioning airspace has not checked.
What this means for your timeline
The permit requirement is the single biggest scheduling constraint on drone cleaning, and it is why drone work loses to rope access on urgent jobs.
| Site type | Realistic lead time |
|---|---|
| Standard commercial building | 3-4 weeks from acceptance |
| Near aerodrome | 4-6 weeks |
| Jurong Island / restricted estate | 6-8 weeks |
| Repeat site with block permit | Shorter - already approved |
If you have a deadline inside three weeks — an event, a handover, an inspection — rope access is likely the practical choice, and we will say so rather than take a job we cannot permit in time.
How to verify a contractor
- Ask for the Operator Permit reference. A legitimate commercial operator has one and will provide it.
- Ask when the Activity Permit for your job will be filed and confirm it is included in the price rather than billed later.
- Ask about pilot licensing for the crew attending your site specifically.
- Ask what the airspace check returned for your address. If they have not run it, they are not ready to quote.
- Ask about insurance — public liability cover appropriate to operating an aircraft over your property.
What the building owner is responsible for
The operating permits sit with the contractor, not with you. Your responsibilities are practical rather than regulatory:
- Site access and authority — confirming you can authorise works on the property, which for MCST and Town Council property means council approval
- Notification to tenants or residents of the working window
- Ground control — assisting with exclusion zones where the working area covers a car park, walkway or forecourt you manage
- Utilities — water and power access where available on site
Frequently asked questions
Is drone cleaning legal in Singapore?
Yes. Commercial drone cleaning is legal in Singapore but requires CAAS authorisation: an Operator Permit for the company and an Activity Permit for each job, applied for at least one month in advance. Pilots must hold a valid Unmanned Aircraft Pilot Licence.
What permits does a drone cleaning contractor need?
A CAAS Operator Permit for the business, a job-specific Activity Permit, and a valid Unmanned Aircraft Pilot Licence for each pilot. Sites near aerodromes require additional airspace assessment, and restricted estates such as Jurong Island require separate JTC clearance.
How long does a CAAS activity permit take?
Applications must be submitted at least one month before the intended operation. In practice, allowing three to four weeks from job acceptance to flying date is realistic, with longer lead times near aerodromes or on restricted estates.
Can I check drone airspace restrictions myself?
Yes. OneMap publishes Singapore drone airspace restrictions at go.gov.sg/dronequery. Entering your building address shows whether the site falls within restricted airspace, which is the first check any contractor should run before quoting.
