What is the difference between EGID and EGRID?
EGID identifies a building in the RegBL; EGRID identifies a cadastral plot. One EGRID can carry several EGIDs, and a building straddling two plots is linked to several EGRIDs.
RegBL
RegBL: the federal register of buildings and dwellings
The RegBL is the Federal Register of Buildings and Dwellings, maintained by the Federal Statistical Office. It assigns an EGID to every building and an EWID to every dwelling, and publishes the construction period, number of floors, use, energy reference area and heating energy source. Known as GWR in German.
Definition and legal framework
The register is fed by municipalities and cantons from building permits: a new build, a conversion or a demolition is recorded as the procedure runs. It is the federal administration's common reference for everything concerning the building stock, and underpins both housing statistics and energy policy.
Its scope is statistical and administrative, not legal: the RegBL describes a building, it creates no rights. Ownership, easements and charges belong to the land register; restrictions enforceable against the plot belong to the RDPPF cadastre. Confusing the three is the most common mistake in a first search.
What it changes for your parcel
It is the source that reliably links a building to a plot. One address can cover several buildings, and a building can straddle two plots: the EGID resolves what a postal address cannot.
Its data also drive concrete decisions. The declared energy reference area sets subsidy amounts per square metre; the heating energy source determines whether a replacement obligation applies; the construction period points to renovation potential.
How to obtain it
The register can be searched publicly by address or by EGID. Always check the record's update date: a recent conversion, heating replacement or extension may not yet appear, in which case the displayed value is the pre-works one.
Frequently asked questions
Does the RegBL prove ownership?
No. The RegBL describes the built stock; ownership, easements and charges are established at the land register, through the notary or the competent office.
Can RegBL data be wrong?
More often out of date than wrong. The register follows building permits: undeclared or very recent works do not appear, and some older values are estimates.
