An elevator position reference system and a method of monitoring building settlement using such a system. The elevator position reference system includes a hoistway extending in a vertical direction. The system also includes a first position measurement tape extending vertically along a portion of the hoistway and an upper tensioning device, connected to an upper end of the first position measurement tape so as to apply a tensioning force in the upwards vertical direction. A lower end of the first position measurement tape is fixed within the hoistway. The system also includes a second position measurement tape extend vertically along at least some of said portion of the hoistway and a lower tensioning device, connected to a lower end of the second position measurement tape so as to apply a tensioning force in the downwards vertical direction.
