Housing and Economic Land Availability Assessments (HELAA) are studies that form part of the evidence base for the preparation of Local Plans. They help identify potential sites that may be deliverable and developable for new housing, employment and other uses over a period that looks forward over the next 15 years (or the period of the Local Plan).

Local Authorities within the Exeter Housing Market Area have worked together since 2007 to produce a methodology for undertaking the housing element of the HELAA (formally referred to as Strategic Housing Land Availability Assessments (SHLAAs). This 2021 version supersedes previous SHLAA/HELAA methodology updates.
