Landmarks Planning, Inc. was a Pittsburgh, Pennsylvania based historic preservation organization operating from 1972 to an unknown date, which had four listed members: Arthur P. Ziegler, Jr., the president, Walter Curtis Kidney, a freelance architectural historian, Eliza F. Smith, the survey coordinator, and Ellis L. Schmidlapp, the secretary-treasurer. There is very little documentation for Landmarks Planning, Inc. but it appears to have been affiliated with the Pittsburgh History & Landmarks Foundation, an extant historic preservation organization based in Pittsburgh, Pennsylvania. The organization coordinated and conducted a survey of 886 historic buildings in Palm Beach for the Landmarks Preservation Commission in 1979-1981, identifying buildings that qualify for National Register and local designation, and historic preservation initiatives.

The Town of Palm Beach passed Ordinance 1-79, the Landmarks Preservation Ordinance, in 1979. This ordinance established the Landmarks Preservation Commission, as well as appoint the Commission with the role of identifying significant structures, subjecting them to a set of objective criteria, and designating them worthy as historic landmarks in the Town of Palm Beach. Barbara Hoffstot, a Palm Beach and Pittsburgh based preservationist, conducted the first building survey of Palm Beach in 1972 and was the driving force behind the passing of Ordinance 1-79. Her affiliation likely initiated the partnership between Landmarks Planning, Inc. and the Town of Palm Beach.
