Asbestos Diagnosis Vaud

The canton of Vaud and asbestos: a varied building stock, precise obligations

The canton of Vaud has one of the most diverse real estate portfolios in Western Switzerland. Lausanne apartment buildings constructed in the 1950s-1980s, single-family villas in the peri-urban municipalities of the Nyon or Morges regions, agricultural buildings in the Gros-de-Vaud and Broye, the classified vineyard heritage of Lavaux and La Côte, industrial facilities in Yverdon-les-Bains or Renens: each of these building types has its own characteristics regarding potential asbestos presence.

Asbestos was banned in Switzerland on 1 March 1990. A significant proportion of Vaud’s building stock was erected before this date — whether in large cities such as Lausanne or Vevey, regional centres such as Yverdon or Nyon, or rural municipalities whose building fabric densified in the post-war decades. These buildings may contain asbestos-containing materials in their roofing, facades, floor coverings, technical installations and secondary structural elements.

Vaud-specific cantonal requirements

The AvT report submitted with the building permit application

The canton of Vaud requires that the building permit application file be accompanied by a pre-works asbestos diagnosis (AvT) when the building concerned predates 1991. This document is submitted to the competent service of the cantonal or municipal administration when the authorisation application is filed. Without this report, the file is incomplete and the application cannot be processed.

This requirement applies to transformation, renovation, extension or partial demolition projects affecting buildings constructed before the asbestos ban. It reflects the project owner’s obligation to demonstrate, before works begin, that they have verified the possible presence of asbestos in the affected zones.

3-year validity

The asbestos diagnostic report submitted with the building permit cannot be more than three years old. A report prepared in connection with a sale, a previous project or an earlier diagnosis, if more than three years old, must be updated before a new application is filed. This rule ensures that the state of materials described in the report accurately reflects the situation at the time of the planned works.

For property owners who had a diagnosis carried out several years ago, it is therefore necessary to check the date of the report before any new building permit application. A partial update may suffice if the materials concerned have not been modified since the initial diagnosis.

FACH-recognised diagnostician listed on vd.ch

The canton of Vaud requires that the diagnosis be carried out by a diagnostician appearing on the cantonal list of recognised specialists, published on the official vd.ch portal. These specialists hold the FACH recognition (Fachkommission Asbest und andere Schadstoffe im Hochbau), issued at the federal level by the specialised commission.

A report prepared by a person not appearing on this list will not be accepted by Vaud authorities in the context of a building permit application. It is therefore essential to verify the diagnostician’s recognition before commissioning them for a mission in the canton of Vaud.

Federal obligation independent of the permit

Beyond the cantonal requirements linked to the building permit, the pre-works diagnostic obligation also derives from federal law. The Ordinance on Construction Work (OTConst, RS 832.311.141) requires the employer — and by extension the project owner — to ensure before any construction site that workers will not be exposed to asbestos fibres. This federal obligation applies even for works exempt from a permit, as long as they are likely to disturb asbestos-containing materials in a pre-1991 building.

Vaud’s built heritage and asbestos risks

Lausanne’s urban heritage

Lausanne alone concentrates a significant proportion of Vaud’s pre-1991 building stock. The popular neighbourhoods of the 1950s-1970s (Bossons, Bourdonette, Prélaz), the apartment buildings of the Lausanne Pâquis, the educational and sports facilities built to accompany the agglomeration’s growth: all these buildings may contain asbestos-containing materials. The rehabilitations and thermal renovations currently underway in the Lausanne agglomeration systematically require a preliminary diagnosis.

The lake and vineyard heritage

The municipalities along Lake Geneva — from Nyon to Montreux via Morges, Pully and Vevey — house a quality building stock, often composed of single-family villas and residential apartment buildings constructed in the first half or middle of the 20th century. These characterful properties have often undergone successive renovations during which asbestos-containing materials may have been introduced or left in place.

The classified vineyard of Lavaux and the wine cellars of La Côte represent another aspect of Vaud’s heritage: old agricultural and viticultural buildings (barns, presses, cellars) may also contain asbestos, particularly in their fibre cement sheet roofing.

Industrial heritage

The industrial zones of Yverdon-les-Bains, Renens, Écublens and Morges concentrate industrial or craft buildings constructed in the 1950s-1980s. These buildings are among those most exposed to asbestos presence: sprayed coatings on metal structures, steam pipe lagging, fibre cement roofing, boiler and furnace insulation. Their transformation for new uses (lofts, creative spaces, commercial premises) invariably requires thorough diagnosis.

School and municipal buildings

The canton of Vaud has numerous school, administrative and sports buildings constructed in the 1960s-1980s to meet the region’s strong demographic growth. These public facilities receive particular attention from municipalities and the canton due to the vulnerable populations who use them.

How an asbestos diagnosis works in the canton of Vaud

Initial contact and preliminary assessment

You provide us with basic information about your building: address, estimated date of construction, nature of the planned works, area concerned. We send you an intervention proposal and a quote within 24 working hours, taking into account the specifics of the canton of Vaud (AvT report for the permit, three-year validity).

Site visit and inspection

The diagnostician inspects the zones concerned by the works, identifies all materials likely to contain asbestos and takes the necessary samples. The inspection follows the protocols recognised by the FACH Commission and covers not only visible zones, but also roof spaces, crawl spaces, technical shafts and service rooms.

Analyses at a SAS-accredited laboratory

Samples are transmitted to a laboratory accredited by the Swiss Accreditation Service (SAS). The results of analysis by Polarised Light Optical Microscopy (PLOM) indicate the presence or absence of asbestos, the type of fibre and, where applicable, the concentration in the material.

Report compliant with Vaud requirements

The final report is structured to meet the requirements of the canton of Vaud for the building permit application. It includes the identification of the property and the mission, the methodology employed, the list of inspected materials, the analysis results, the risk assessment for each positive material and the pre-construction site recommendations. This document satisfies both the Vaud cantonal requirements and the federal obligations arising from the OTConst.

Frequently asked questions — Vaud

My diagnostic report is four years old. Can it still be used for a building permit in the canton of Vaud?

No. The canton of Vaud requires a report less than three years old. If your report is more than three years old, it will need to be updated before filing your permit application. A new partial inspection may suffice if the materials concerned have not been modified since the initial diagnosis and the inspected zones are identical.

Is a diagnosis required for an interior renovation that does not require a building permit in the canton of Vaud?

Yes. The pre-works diagnostic obligation on pre-1991 buildings derives from federal law (OTConst), independently of the cantonal obligation linked to the permit. Even for works exempt from a permit, diagnosis is required if the works are likely to disturb potentially asbestos-containing materials.

How do I verify whether a diagnostician is recognised in the canton of Vaud?

The list of recognised diagnosticians is published on the official vd.ch portal. You can also ask us to confirm the FACH recognition of our experts and their presence on the Vaud cantonal list before any intervention.

Does the diagnosis cover the entire building or only the works zones?

The diagnosis can be targeted at the zones concerned by the works alone (partial pre-works diagnosis), or cover the entire building (comprehensive diagnosis). For a Vaud building permit, the minimum zone to inspect is that directly affected by the planned construction site. A comprehensive diagnosis is advisable if you plan phased works over several years, in order to avoid multiple interventions and to have a complete picture of the condition of your building.

Can I use a diagnostic report carried out for a property sale to file a building permit application?

Yes, provided the report is less than three years old, was carried out by a FACH-recognised diagnostician listed on vd.ch, and covers the zones concerned by the planned works. If all these conditions are not met, an update or additional diagnosis will be necessary.
