Another option for increasing public ownership of private properties is the use of community land trusts (CLTs). These organizations are typically nonprofit entities that acquire land and convey the land to building owners through a ground lease. By owning the land, CLTs ensure that properties sited on the land are affordable in perpetuity.
Historically, private groups drove the creation of CLTs but local governments have increasingly been involved in forming CLTs in their communities. Chicago was the first major city in the United States to establish its own CLT. In Chicago, the CLT is unique because it does not own the land. Instead, the CLT uses deed restrictions in order to avoid the challenges of land acquisition while maintaining affordability. State and local governments have also provided financing to CLTs to help them acquire land.
Nonprofit Housing Acquisition
In San Francisco, the city’s Small Sites program is designed to preserve affordability of small multi-family buildings (4 to 25 units). The program does this by giving funding to nonprofits to purchase such buildings that would otherwise likely be purchased by profit-driven entities that would displace tenants.
