The study, conducted by the Centre for Research on Architecture, Society and the Built Environment (CASE), concluded that 28 percent live in more than one residence during the course of a year.
Another 20 percent had experienced living in more than one home, meaning almost half the population has lived with multiple addresses, often in different parts of the country.
CASE is based at Zurich's Federal Institute for Technology (ETH) and conducted the study with the University of Basel and the Lucerne University of Applied Sciences and Arts.
The research found that 68 percent of those with multiple residences had access to two homes, while 23 percent had three and nine percent had four or more, the centre said in a news release.
The extra lodgings serve multiple purposes, so it is not always possible to lump them as principle and secondary residences, CASE said.
But more than two-thirds of supplementary residences are used for activities linked to leisure, while a quarter of such homes are linked to work or study purposes.
More than half of extra residences serve as a place for living jointly or separately with a partner.
The results of the study are based on a poll of 3,246 people aged 15 to 74, in addition to a more detailed survey of 961 people living in multiple residences.
Conducted between 2012 and 2014, it was funded by the Swiss National Science Foundation.
