3.52.

Where the district boundaries are not otherwise indicated, and where the property has been or may hereafter be divided into blocks and lots, the district boundaries shall be construed to be the lot lines. Where the districts designated on the map are bounded approximately by lot lines, the lot lines shall be construed to be the boundary of the district unless the boundaries are otherwise indicated on the map.

In un-subdivided property, the district boundary lines on the map shall be determined by use of the scale appearing on the map.
