Housing conditions 3-1: Housing Stocks

The total number of homes and the number of residences with households continuing to increase.
As of October 1, 2018, the total number of houses in Yokohama City was 1,835,800, of which 1,649,000 houses have resident households, which can be said to be sufficient in terms of the number of units.
In addition, with the increase in the number of houses, the number of vacant houses is also increasing. The ratio of the number of vacant houses to the total number of houses has decreased slightly since the 2013 survey due to an increase in the total number of houses, but since it still accounts for about 10%, effective use of stock is desired (Fig. 3-1-1).

※The term "vacant house" here refers to a house that has become an unoccupied house for rental or sale. The “number of vacant houses” does not include houses that are used only in the daytime, or houses under construction, so the difference between the “total number of houses” and “number of houses with resident households” does not match .

The ratio of houses over 30 years old and houses about 30 years old were 25% in 2008 (built before 1980), but in 2018 it was 37.2% in 2018 (Building before 1990), and the proportion of old houses is increasing (Fig. 3-1-2).
For this reason, the structural parts and equipment of houses are aging, and the obsolete of housing functions are progressing, and it is necessary to secure a good living environment while promoting appropriate renovation and renewal.

From 2013 to 2018, there was no ward where the increase rate of the total number of houses exceeded 10%.
As of 2018, nine wards with a total of more than 100,000 houses are Tsurumi Ward, Kanagawa Ward, Minami Ward, Hodogaya Ward, Konan Ward, Totsuka Ward, Asahi Ward, Aoba Ward and Kohoku Ward. (Fig. 3-1-3).
