Condominium ownership in Zurich: regulations, management and renovation funds

Condominium ownership is a special form of co-ownership governed by Articles 712a–712t CC. The buyer acquires a share in the whole property together with an exclusive right to use and fit out specified parts, usually the apartment and assigned ancillary rooms. Structural elements, roofs, façades, staircases and technical systems generally remain common property. This distinction determines who pays for work and who can decide on it.

Each unit has a value share, often expressed in thousandths. It generally determines the share of common costs under Article 712h CC, including insurance, administration and renovation-fund contributions, and is relevant to voting under Article 712m CC. Check whether the share corresponds to the unit’s size and situation: its consequences continue for the duration of ownership.

The co-owners’ regulations are the central internal rules. They govern exclusive and common areas, administration, meetings, required majorities, managerial powers and building work. Usually noted in the land register with the establishment deed, they bind subsequent purchasers. Review provisions on pets, short-term letting, alterations and voting restrictions before committing to the purchase.

House rules supplement the regulations by addressing quiet hours, laundry rooms, bicycle storage and common outside areas. They are normally easier to amend than the regulations themselves. The owners’ meeting is the community’s supreme body under Article 712m CC. Different decisions require ordinary, qualified or unanimous majorities according to their nature and importance.

Appointment of an administrator is provided for under Article 712q CC but is not mandatory in every case. Larger communities generally use professional management, while smaller ones may organise matters among owners. Articles 712s and 712t CC address day-to-day administration, implementation of resolutions, meetings, accounts, urgent action and external representation. Clear minutes, understandable accounts and timely responses indicate how the property is managed.

A renovation fund is not generally mandatory by law, but is commonly provided for in the regulations. It finances major work such as roofs, façades, heating, lifts and pipes. A frequently cited annual contribution range is 0.3–1.0% of the building’s replacement value, although the actual requirement depends on age, condition and previous maintenance. A low fund combined with imminent repairs can mean significant future special contributions.

Review the regulations and house rules, minutes for the past three to five years, annual accounts and current budget, renovation-fund balance and evidence of its assets, the five-to-ten-year investment plan, outstanding defects and claims, and building insurance. Minutes often reveal disputes, voting patterns and deferred work absent from sales material, including conflicts with neighbours, developers or contractors.

Where renovations are planned or under way, the purchase contract should allocate approved but unpaid special contributions, the treatment of any renovation-fund share and work not yet invoiced. Without a clear agreement, liability can depend on ownership at the relevant time, creating surprises. A specialist can assess the contract alongside community regulations, resolutions and finances; the outcome depends on the individual case.
