When American occupation forces after the war began to bring their families with them for three or more years of duty, there was no "base" or "post" housing at the time. Civilian neighborhoods, usually in the suburbs that were undamaged by wartime bombing were selected for American housing. Army officials with a German translator would knock on the door and tell the residents they had a couple days to pack up and leave. Paperwork would be given them and the US Army did pay them rent. But they had to leave and go where ever they could find another place, usually with relatives or friends in the inner city or countryside.
And then the American families moved in. Army contracted maintenance teams kept up the homes and utilities. This continued through the 1950's. By the late 1950's German requisitioned homes were gradually all returned as US military housing centers were built in conjunction with and near to DOD American schools, BX's and commissaries. Most new American housing were apartments up to four bedrooms for large families, all on one floor. Some senior officers had duplexes and the most senior and local commander had a single family house.
And the German community rebuilt their downtowns and their neighborhoods. Requisitioned homes were all returned, I believe, by the early 1960's. The owners moved back in and in most cases did remodeling and modernizing. Many of these homes built at the turn of the century remain today in this new century.
That some German people lost their homes to US families in the late 40's and 50's seems harsh, but they did receive compensation in an amount that they then could not earn themselves in immediate postwar Germany. And this compensation collectively contributed significantly to the rebuilding of the German postwar economy. Also the spending of American families was even a greater contributor to the rebuilding of the economy.
As a school age child, I lived in a requisitioned house for a few years in a nice wooded area on the edge of Wiesbaden. My father was stationed there in the mid 1950's. I recall a knock at the door one Sunday afternoon. My father answered and an older, taller gentleman, apologetically introduced himself as the owner of the house and wondered if you could have permission of see the fruit trees in the back yard he had planted many years earlier. Technically this was in violation of occupation rules and codes, but my father was sympathetic and welcomed him to see his house and his yard. The man broke into tears when he viewed a cherry tree in the back full of ripening fruit. Dad then sent us kids up the tree to pick a basket of cherries to give to this visitor/owner.
The owner was grateful for the gift and was complimentary of the Americans taking care of the house and upgrading some plumbing, electrics, and the heating system which I recall was coal fired. Another civilian contractor would show up each morning to shovel coal into the fire pit to heat the boiler for our heat and hot water. And again my parents were friendly towards this person and would give him gifts or leftover food and pastry, then well received.
The German people of the 1930's supported and put Hitler in power. They supported his war and the deportation and killing of the Jews. These basic facts remains hard to understand to this day. But post war Germany seemed repentant; and a different and better Germany evolved to today. As kid living there in the 1950's I only experienced good Germans though they were a part of the war. As an adult visitor in the 2010's the current generation are good and different people and know very little of World War 2.
