Building Passport and Czech Construction Law
A general explanation of Czech building-record obligations, building passports and the limits of simplified as-built documentation.
Czech law requires owners to retain documentation corresponding to the actual execution of a building. Where records are missing or inadequate, a simplified building passport may be relevant.
Owner's records
An old design is not sufficient when the building has clearly changed.
Content
The scope follows Decree No. 131/2024 Coll., the building type and the intended administrative use.
Professional input
Complex, official or design-related cases may require an authorised professional; confirm this before commissioning.
No automatic legalisation
A passport records conditions. It does not itself approve unauthorised work.
Need deliverables that remain usable
Before commissioning the work, define the purpose, survey scope, required accuracy, deliverable formats and acceptance checks in writing. DigiStav provides surveying, building records, 2D documentation, point clouds and BIM-ready outputs for buildings, infrastructure and industrial assets. The scope should always follow the intended use rather than a generic package.
This article provides general technical information. It is not a substitute for project-specific legal, surveying, engineering or professional-authorisation advice.
