The foundation aims to build, operate and rent affordable housing for the elderly in Zurich-Witikon on a non-profit basis. People of pension age who are connected to the Witikon district are eligible for admission. Exceptionally, other persons may also be admitted. The foundation is politically and denominationally neutral. The construction of subsidized housing is permitted, but apartments should also be created whose users are not subject to any restrictions in terms of income and assets. The foundation does not pursue any commercial purpose and does not aim to make a profit. However, the rents must be cost-covering. The foundation's properties are fundamentally non-transferable.
