Last year, the number of residential development permits rose by 5.4% to 284,900 units. Figures from the Federal Statistical Office show that this continues the upward trend since 2010, but at a considerably weaker rate than last year. In 2013, permits had still increased by 12.9%. Permits for units in apartment buildings, up 8.8%, showed the lowest growth rate since 2010. For one- and two-family homes in 2014, the statisticians even found decreases of 1.4% and 5.8% respectively. However, a significant plus (31.8%) occurred again for dormitories and permits for non-residential buildings also were again slightly up (+7.0%). Office space building volume, however, declined 7.3%, and a slight (1.3%) decline occurred in the "trade and warehouse" category.
