2006 New York Code - Foundation Operations Affecting Adjacent Properties.

 
    §   27-1029   Foundation  operations  affecting  adjacent  properties.
  Whenever subsurface operations are conducted that may  impose  loads  or
  movements on adjoining property, such as driving of piles, compaction of
  soils,  or  soil  solidification,  the  effects  of  such  operations on
  adjoining property and structures shall be considered. The owner of  the
  property  that  may be affected shall be given forty-eight hours written
  notice of the intention to perform such operations.  Where  construction
  operations  will  cause changes in the ground water level under adjacent
  buildings, the effects of such changes on the stability  and  settlement
  of  the adjacent foundations shall be investigated and provision made to
  prevent  damage  to  such  buildings.  When  in  the  opinion   of   the
  commissioner  a  potential  hazard  exists,  elevations  of the adjacent
  buildings shall be recorded by an architect or engineer at intervals  of
  twenty-four hours or less as determined by the commissioner to ascertain
  if movement has occurred.
