Software and a tablet app to renovate occupied homes
Legendre renovates buildings while the tenants live in them. We replaced paper with a tablet app and a web back office, from the inspection to the signed sign-off.
- The need
- On a renovation site in occupied housing, every home gets an inspection before the works, then a sign-off at the end of each work package. It was all done on paper. Site managers chased forms, photos and signatures, and finding the history of a home took time.
- What we built
- An Android tablet app to inspect each room, floor, walls and ceiling, with photos
- Markers placed on the floor plan to locate every remark
- An occupant sheet to prepare the works, elderly people, children, pets, night shifts
- A sign-off per work package with the tenant's reservations and signature on the tablet
- The PDF sent by e-mail after each signature
- A web back office with homes, tenants, inspection and sign-off tracking, bulk exports and text messages
- A satisfaction survey rated by the tenant at the end of the works
- How we worked
- We first followed the site managers in the field to match how they work. Signal is rare in a building under works, so the app works offline. Photos are resized and kept in an upload queue on the tablet until the network comes back. Each new site opens with its accounts, plans and tablet, and since late 2025 every site runs on the same version.

- The result
- The first site started in late 2023 in Cognin, with 240 homes. The tool then followed Legendre to five more sites, in Chambéry, Saint-Priest and Vaulx-en-Velin. Inspections and sign-offs no longer go through paper, and every home keeps its full history.
