Start with the cantonal property-information service
The cantonal Grundstücksinformation entry opens the Web GIS Client. Find the property and select the relevant parcel. Keep the connection between its address and parcel number clear in your records. Where several buildings are involved, or a purchase includes additional land, check that every part has been identified. Save a readable map view and add a short list of the components actually included in your enquiry, rather than assuming one address describes them all.
Distinguish selected layers from a complete extract
The canton explains that PLR themes can be combined in the viewer and that a parcel summary can be downloaded as a PDF. The document connects plans with provisions and legal bases. A custom view with just a few layers should therefore not be described as a complete property investigation. For questions about building lines or water protection, keep the particular entry. If its meaning is unclear, ask the responsible office rather than deriving a rule from the visual display alone.
Keep technical details and actual use traceable
For a house, collect plans, construction-year and heating information, and dated renovation records. For a rented property, available tenancy records and the actual use of the units may be relevant; initially describe which documents you hold. For a condominium, add records concerning shared works. For land, distinguish infrastructure already available from possibilities still uncertain. Label assumptions clearly so gaps in the file do not silently become accepted facts during the assessment.
Official sources to prepare your enquiry
These sources describe the location and property records. They do not calculate an individual market value.
Frequently asked questions
Is a map showing only selected PLR layers enough?
It helps answer a particular question, but is not the same as a complete review. Record which themes were visible or hidden. A parcel-specific extract and its associated documents make the preparation easier to trace and preserve the context.
How should I describe a purchase including a house and another plot?
Give both parcel references and describe their present use. Explain whether the additional land should be included in the assessment. One address or a combined area figure can otherwise conceal the need to examine different documents.
What does a valuation cost and how is a visit arranged?
Your enquiry is non-binding and does not commit you to selling. The first conversation covers your purpose, the scope of the service, any fees and arrangements for a visit. Explain any deadline or particular intended use before commissioning a service.
