Kreis 6: Unterstrass and Oberstrass
Kreis 6 comprises the two neighbourhoods of Unterstrass and Oberstrass. The buildings rise from the valley floor towards the Zürichberg; old buildings with attic apartments are common.
Attic apartments in particular quickly get hot in summer. A well-placed split unit provides relief – provided the pipe route and outdoor unit suit the house and the neighbourhood.

Permits and noise protection in Kreis 6
In condominium ownership, an outdoor unit usually requires the consent of the owners’ association. We provide the necessary information on the unit, location and sound levels.
In the Canton of Zurich, many air/water heat pumps can be installed under the notification procedure (placed indoors or outdoors up to 2 m³); in core zones and in areas with townscape or monument protection, outdoor units still require a permit. A noise protection certificate is always required for air/water heat pumps (Canton of Zurich). The City of Zurich accepts projects subject to notification via eBaugesucheZH; we compile the documents for you.
Official information without guarantee – the requirements of the city and canton are authoritative.

FAQ
Questions from the region
What do I need for an air conditioning system in condominium ownership?
As a rule, the consent of the association and – depending on the location – clarification with the building authority. We compile the documents.
Can I also use the air conditioning for heating?
Split units work as air/air heat pumps and can heat in the transitional season. Whether that makes sense, we discuss during the consultation.
