The initial funding was $100,000 from a personal estate. The organization's first revolving fund for rehabilitating buildings was initiated around 1980. The first project using the fund was rehabilitation of 1063, 1065, and 1435 Oak Street, National Register-listed properties. Headquarters The organization is headquartered at 57 Jefferson Avenue, part of the Jefferson Avenue Center in Downtown Columbus, and a contributing building to the Jefferson Avenue Historic District. The building is a two-story residential-style structure with a mansard roof. It has narrow windows with incised lintels, similar to other buildings in the historic district. Towards the building's cornice are small rectangular frieze windows. The south façade includes a full bay window. An addition to the building's south side is of an unknown age. The property is separated from the sidewalk by an iron fence with limestone posts. Endangered properties list Columbus Landmarks publishes an annual list of the most endangered properties in the city. The list is aimed to raise awareness to the sites' history and redevelopment potential. The endangered site list was first released in May 2014. Sites added to the list are left abandoned or at risk of demolition, are at least 50 years in age, and contribute to the value and culture of Columbus. Areas that have faced historical disinvestment the Hilltop, Linden, Milo-Grogan, King-Lincoln Bronzeville and the South Side are prioritized on the list. Design award Columbus Landmarks also hosts the annual James B. Recchie Design Award, given to quality urban designs for new and existing buildings, parks, public art, and other spaces.
