- Municipal building control
For a building-control authority, control.io is a way to watch many permitted sites at once. Permit conditions and approved programmes become milestones, scheduled drone flights record what exists, and the office sees which projects are stalled, ahead of permit, or out of step with what was approved.

Problems and answers
Check permitted works against what is being built, across many sites, without sending an inspector to every one.
- 01
The problem
Inspectors cannot visit every active permit often enough.
With control.io
Scheduled flights cover many sites, and inspectors go where the data shows a problem.
- 02
The problem
Abandoned or stalled projects are noticed late.
With control.io
A site with no measurable change between flights is flagged automatically.
- 03
The problem
Enforcement needs dated, attributable evidence.
With control.io
Every image carries capture time, location and a hash, and is tied to the permit clause it concerns.
Deliverables
- City-wide map of monitored permits and their status
- Permit-linked milestone extraction with page citations
- Stalled-site and deviation alerts
- Dated, hashed image evidence per inspection
- Exportable reports for enforcement files
Can control.io tell if a building exceeds its permitted height?
The 3D reconstruction measures heights and storey counts, which can be compared with the permitted envelope. A qualified officer should confirm any finding before enforcement.
Who flies the drones for a municipality?
control.io's certified pilots, or the municipality's own drone team using our flight plans and upload app.
Does it work with scanned paper permits?
Yes. Scanned permits are read with OCR and every extracted condition keeps a link to the scanned page for review.
