Unlike debates about security for owner occupiers which recognise that security is complex and multi-layered, security for renters is often presented as single dimensional and conflated with de jure security of tenure, deriving from a property rights perspective. This article proposes a broader concept of 'secure occupancy' to enable a more nuanced understanding of security for tenants. A new framework is developed to enable investigation of the dynamic interactions between legislation/regulation, housing market conditions, public policies and cultural norms around renting, which shape security of occupancy for tenants. The paper illustrates this approach, drawing on a study of the rental systems of nine developed countries, identifying key factors that appear to have a strong bearing on strengthening, and weakening, of security of occupancy for renter households. The article concludes that this approach has the potential to deepen understanding of security for renters and to stimulate new avenues for research.
