Swiss property due diligence · source-checked

How it works — what's in a brief

You enter a Swiss address. alpflo resolves the parcel, queries the public registers, and compiles a brief in which every field carries its provenance.

What is checked
Building (GWR)

Federal Register of Buildings and Dwellings, Level A: building identity, construction and energy data — as a register value, not as truth.

Zoning & land use

Building zone and land-use plan from the canton's ÖREB cadastre.

ÖREB restrictions

Public-law restrictions on landownership — binding vs. informative, with legal reference and force-of-law status.

Modelled context

Public-transport quality class (© ARE), roof solar potential (© SFOE), and the energy certificate where available — derived, not directly from the register.

The four states

Every field shows exactly one of these states. That is the promise: make visible what is established and what is not.

On record

Confirmed in an official Swiss register. Direct source.

None recorded

Register queried; nothing on this parcel. The absence is documented.

Modelled

Derived from a model or an API: real, but not directly from the register. Please verify.

Could not resolve

Hit an edge case. Stated honestly at the boundary, never silently discarded.

Frequently asked questions
What is an alpflo brief — and what is it not?

An alpflo brief gathers publicly available Swiss register data about a parcel — building, zoning, ÖREB restrictions, and modelled context, with proof of provenance on every field. It is not an estimate, not legal, construction, or financial advice, and no substitute for review by a professional.

Which cantons does alpflo cover today?

alpflo resolves addresses to buildings and parcels across Switzerland. Binding ÖREB restrictions are connected today in the cantons of Zurich, Zug, Basel-Stadt, Aargau, Bern, and Schwyz; the list grows with each new canton.

What do the four states in a brief mean?

Every field shows exactly one of four states: confirmed on the register, register queried with nothing recorded, derived from a model, or an edge case disclosed honestly rather than silently discarded.

What does alpflo deliberately not cover?

alpflo does not cover natural hazards (flood, landslide, rockfall, avalanche), value estimates, or heritage / ISOS protection status. That is a deliberate choice, not a register gap.
