Aerial imagery has become practically standard for commercial properties, plots and larger residential developments. It shows location, layout and surroundings in a way impossible from the ground. What is regularly underestimated: commercial drone use is clearly regulated, and responsibility does not rest with the pilot alone.
This article gives an overview of the essentials under German and EU rules. It does not replace legal advice – seek professional guidance in genuine doubt.
Commercial use usually starts with the agent
A widespread misconception holds that only selling the imagery counts as commercial. In fact use already counts as commercial when the images serve marketing – including when the agent flies personally to promote their own property.
The requirements of the EU drone regulation therefore apply in full.
What the pilot must demonstrate
For typical use over built-up areas, depending on drone class and weight, at least an EU competence certificate is required, and in many constellations the extended remote pilot certificate. In addition:
- Registration as an operator with the aviation authority; the number must be affixed to the drone
- Liability insurance that expressly covers commercial drone operation
- Knowledge of the applicable distance and altitude rules at the specific site
Ordinary private liability insurance does not cover commercial flights. Anyone flying without a suitable policy is personally and unlimitedly liable in the event of damage.
Where flying is prohibited
Geographical no-fly and restricted zones are binding and change. These include areas around airports and landing sites, nature reserves, certain industrial installations, federal trunk roads, and areas around authorities and police facilities.
Over built-up areas additional requirements apply regarding drone class and distance to uninvolved persons. Overflying gatherings of people is generally excluded.
A current check of the zone situation therefore belongs before every flight – not the memory of the last one.
Neighbours' personality rights
This is where most practical conflicts arise. From the air the camera inevitably captures neighbouring plots. It becomes critical when protected areas are recognisably filmed – for instance an enclosed garden or through windows.
The practical consequence for publication: neighbouring plots should not be recognisable in detail, and people and number plates must be made unidentifiable. Anyone wanting certainty obtains consent in advance in close neighbourly situations – that costs a conversation and prevents a dispute.
Who is liable when something happens
Formally the operator of the drone is liable. What matters for you as the client is that a poorly documented commission can fall back on you in a dispute – for instance if you engage a pilot without the necessary credentials and could have recognised this.
Have the competence certificate and insurance confirmation presented before the assignment. A reputable provider supplies both unprompted.
When aerial imagery is worthwhile at all
Not every property benefits. Drone imagery makes sense above all for:
- Plots – layout and boundaries only become comprehensible from above
- Commercial and logistics property – access, manoeuvring areas, roof condition
- Properties with a locational advantage – lake, forest, edge of town, skyline
- Construction projects – progress documentation from a recurring perspective
They bring little benefit for flats in multi-storey buildings or in dense terraced housing, where the aerial view mainly shows neighbouring roofs.
The combination makes the difference
Aerial imagery alone does not carry a brochure. Its strength emerges in combination with ground photography and, for larger properties, with a property video in which the flight forms the opening and leads into the interiors.
For construction projects, recurring aerial images complement 3D construction documentation: what the scanner achieves indoors, the drone covers outdoors – excavation, storeys, roof structure, facade.
If you do not want to carry the legal effort yourself, we handle drone imagery including permit situation, insurance and credentials.
Checking insurance cover concretely
The most common mistake when commissioning concerns insurance. Business or private liability policies generally do not cover commercial drone flights; what is needed is a policy expressly extended to unmanned aircraft with an adequate sum insured. Have the confirmation presented before the assignment, not afterwards. Also check whether the policy includes the specific purpose – some contracts exclude flights over built-up areas or commercial contract work. A provider unable to supply these documents within a day is probably working without them.
The pilot's documentation duties
Alongside authorisation and insurance there are record-keeping duties that become relevant in the event of damage: flight log, checking the zone situation before take-off, weather conditions, equipment used. For you as the client this matters because incomplete documentation weakens everyone's position in a dispute. For larger properties and recurring assignments it is worth agreeing the documentation as part of the service and archiving it with the image files. It costs nothing and, if it comes to it, is the difference between a clarification and a confrontation.
Imagery over third-party land
Overflying a neighbouring plot is legally more delicate than practice suggests. While there is no absolute prohibition at every altitude, interference with property and privacy can trigger injunction claims – particularly at low altitude over enclosed areas. For marketing that means practically: plan the flight route so it runs over your own plot and over public ground. Where that is not possible, have the conversation with the neighbour beforehand. A brief word before the appointment regularly prevents the complaint afterwards.
What to observe in post-processing
Legal requirements remain after the flight. Recognisable people, vehicle registration plates and house numbers of neighbouring buildings must be made unidentifiable before images are published. For properties in dense development that is retouching effort which should be planned in. Also ensure aerial images do not show security-sensitive areas – for properties near railway installations, power plants or judicial facilities, even publication can be problematic. When in doubt: whatever is not needed for the marketing comes out of the image.
When buying your own drone pays off
Many agencies consider a purchase. Calculate realistically: on top of the device come the competence certificate, insurance, registration, spare batteries, software and above all the time to gain practice and check the zone situation before every flight. Anyone with fewer than roughly twenty assignments a year is cheaper off commissioning – and carries no liability risk. At higher frequency an in-house operation can pay off, but should then be clearly assigned to a person. A drone flown by rotating staff without routine is the most expensive route of all.
