Suppose you are selling a house in the old village centre of Trübbach or Azmoos. Does the ongoing local plan revision matter for your building?
Quite possibly. In December 2025, the council enacted the new framework plan, including a partial revision of the townscape protection ordinance.14 In the Plattis area, Müller Azmoos AG, a major employer, is also planning a new energy centre.15

Without official prices
What is a house in Wartau worth without official price statistics?
Official statistics on prices paid are missing for Wartau. The Canton of St. Gallen does not collect them by municipality, unlike the Canton of Zurich. Listing figures for Wartau show what is asked, not what was paid.
What is on record is the stock: Wartau has 1,708 buildings with residential use in the Werdenberg constituency. 1,122 of them are single-family houses, or 65.7%. The cantonal figure is 59.2%. Wartau ranks 3 of 6 in the Werdenberg constituency. In total, Wartau has 2,791 dwellings. 62.9% were built before 1981, against 58.9% in the canton. 10.1 hectares of 187.6 hectares of building zone are undeveloped, or 5.4% (as of 2022).

Current in Wartau
What do the local plan revision and the Plattis energy centre mean for a sale in Wartau?
The municipal council enacted the framework land-use plan on 9 December 2025. It covers zoning maps for Wartau, Oberschan-Weite and Trübbach-Azmoos, and a building code.14 It comes with a partial revision of the townscape protection ordinance. The documents went on public display from 2 February to 3 March 2026.14 New municipal street plans and footpath, hiking and cycle route plans went on display at the same time.14
In the Plattis area, Müller Azmoos AG, a vegetable-processing firm, intends to build an energy centre and a drainage project.15 To allow this, the municipality is amending the Plattis III special-use plan. Public consultation ran from 25 November to 24 December 2024.15 According to the planning report, the firm provides a large number of jobs and is of great importance to the municipality.15
For sellers in Wartau, both matter. The new zoning rules will govern future building once they apply. Many homes in Wartau also date from before 1981, which can make townscape protection important to buyers.

Selling in the Canton of St. Gallen
What applies when selling in the Canton of St. Gallen: tax, land registry, notarisation?
The canton taxes the gain on sale, price minus costs, on a progressive scale.2 After more than 15 years of ownership, the tax falls yearly, by up to 40.5% if you lived there 15 years or more.2 This applies to the gain up to CHF 500,000; otherwise the cap is 20%.2 Within 5 years, the tax rises.2
Selling a home you lived in permanently and exclusively can defer all or part of the tax.3 You buy a similarly used home in Switzerland from 1 year before to 3 years after the sale.4 Deferred does not mean waived.3
The buyer owes a 1% transfer tax (Handänderungssteuer) on the price.5 The seller is jointly liable; between parents and children, half the rate applies.5
The municipal land registry where the property lies notarises the sale contract.6 The registry fee is 0.2% up to CHF 2 million, 0.05% above.7 If the land registry also notarises the contract, the fee doubles.7
