358 MÜLHAUSEN. The building by-laws of the Town Council regulate the construction of dwellings in great detail, though no attempt is made to apply their sanitary provisions to old property in a rigorous spirit. As to new houses, it is laid down that five stories, including ground floor and attic, may not be exceeded, though in two quarters of the town, one residential and the other industrial—Rebberg and Cité respectively—there may only be one story besides the ground floor and attic. As a rule one-fifth of a building plot, with a minimum of 48 square yards, and a width of at least 9 feet 9 inches, must remain open ; though where a site abuts on two streets the proportion may be reduced to one-eighth. The height of buildings (i.e., of the outer walls), lining with a street, or within 13 feet of the same, may not exceed the width of the street by more than 6 feet 6 inches, and may not exceed 58 feet 6 inches, or be less than 29 feet 3 inches. Side and back houses are subject to the same conditions as front houses, but the width of the courtyard instead of the street is here taken. Living rooms must have a clear height of at least 9 feet 1 inch, and in the attic one of 8 feet 1 inch for at least one-half of the floor surface ; whilst both living and bedrooms must not be less than 7 feet 1 inch wide, with a superficial area of 9'6 square yards. Basement dwellings are forbidden, and the floors of work rooms may only be 4 feet 10| inches below the surface, and even then must be free from damp. As to attic rooms, it is provided that they may only be used for permanent human habitation when they have plastered walls and ceilings and vertical windows. The usual accommodation of working-class families in Mülhausen is two or three rooms and a small kitchen, though tenements of one. room and a kitchen, and even of a single room, are not uncommon. Where working-people rent three rooms and a kitchen, it is usual to take lodgers should the size of the family allow of it. No complete classification of the tenements of the town has yet been attempted, but a record has been kept of new houses which have been erected since 1899, and it shows clearly that, taking the population generally, the preponderant demand is for tenements of three rooms. The following figures may be cited in proof of this statement :— Number of New Houses erected during the years 1900-1905, with Number of Tenements comprised therein and Classification of Tenements according to Rooms, the Kitchen being counted as a Room :— Year. 1900 1901 1902 1903 1901 1905 Totals Percentages New houses. 61 41 61 69 65 88 385 Number of tenements contained therein. 222 170 194 249 189 357 1,381 One room. 18 Two rooms. 1-3 46 26 16 9 12 45 154 Three rooms. 11-2 142 113 119 91 102 185 752 545 Four rooms. 26 15 26 103 17 72 259 18-7 Five rooms. 3 5 16 23 7 20 74 5 4 More than five rooms. 5 9 16 20 43 31 124 9-0 The returns of the Municipal House Bureau show that for all tenements of two rooms and a kitchen reported vacant tenants are found, and that the wants of the great majority of house seekers do not exceed three rooms. Thus, during the year 1904-5, 597 tenements were -reported to the Bureau as vacant, and of these 89 were of one room, 135 were of two rooms, and 201 of three rooms, these forming 71 per cent, of the whole. Of 532 tenements reported to the Bureau as having changed hands during that year, 61 were of one room, 135 (the total offered) were of two rooms, and 188 of three rooms, these forming 72 per cent, of the whole.
