Saint-Sulpice's housing stock in figures
The federal building register lists 664 residential buildings with 2'639 dwellings in Saint-Sulpice. 55% were built before 1980, before serious insulation standards, and 66% are still heated with oil or gas.
Only 19.9% of residential buildings in Saint-Sulpice report a solar thermal system in the register, so most roofs are still free. Photovoltaics are not recorded there; check the solar cadastre for your roof.

Renovations, heritage and volumes
For renovation planning in Saint-Sulpice, official building register figures provide essential insights. With one building formally listed under heritage protection, property owners must contact the municipality early to understand specific permit requirements. Regarding building volume, data is partial, covering only 113 out of 341 houses measured according to the SIA 416 standard. For these properties, the median volume is 1068 cubic meters, which serves as a key indicator for scaling insulation improvements or heating system upgrades. Please note that these figures represent a limited portion of the total housing stock currently recorded in the register.

Rules of the canton of Vaud
These rules apply across the whole canton, not only in this town.
Permits
- Legal basis : LATC et RLATC (BLV 700.11 et 700.11.1)
- Competent authority : Commune concernée, avec consultation des services cantonaux selon le projet
- Heat pump : Pour certaines pompes à chaleur desservant un bâtiment existant, une procédure d’annonce est prévue par l’article 68c RLATC, sous conditions. Si les conditions ne sont pas remplies, une procédure de permis de construire est nécessaire. Vérifiez votre cas auprès de la commune.
- Procedure : La procédure dépend de la nature des travaux et de la situation du bâtiment ; la commune confirme la procédure applicable.
Tax deductions
- Note : Le contribuable peut choisir, lors de chaque période fiscale et pour chaque immeuble, entre la déduction des frais effectifs et la déduction forfaitaire. La déduction forfaitaire couvre les frais d'entretien, de remise en état d'immeubles acquis récemment, d'administration par des tiers, d'investissements énergétiques, de démolition et de primes d'assurances.
- Carry-forward : Si les coûts d'investissement destinés à économiser l'énergie et à ménager l'environnement ou les frais de démolition en vue d'une construction de remplacement ne peuvent pas être entièrement pris en considération fiscalement durant l'année où ils ont été engagés, le solde peut être reporté sur les deux périodes fiscales suivantes. Les dépenses peuvent être reportées si le revenu net est négatif. Si des frais sont reportés, il n'est pas possible de faire valoir une déduction forfaitaire pendant cette période fiscale. En cas de déménagement en Suisse ou de transfert de la propriété de l'immeuble, le contribuable conserve le droit de déduire le solde des frais pouvant être reportés.
- Maintenance costs : Le contribuable qui possède des immeubles privés peut déduire les frais nécessaires à leur entretien, les primes d'assurances relatives à ces immeubles et les frais d'administration par des tiers.
- Energy investments : Sont réputés investissements destinés à économiser l'énergie et à ménager l'environnement les frais encourus en vue de rationaliser la consommation d'énergie ou de recourir aux énergies renouvelables. Ces investissements concernent le remplacement d'éléments de construction ou d'installations vétustes et l'adjonction d'éléments de construction ou d'installations dans des bâtiments existants. Si les mesures sont subventionnées par la collectivité publique, le contribuable ne peut déduire que les frais qu'il assume lui-même. Le taux de déduction est de 100%.
