Social housing tenants who have to leave their properties due to a "significant mass emergency event" will move up one housing band level in proposals by a city authority.
Bristol City Council is holding a consultation on changes to how it allocates social housing.
There are approximately 22,000 households currently bidding for homes, and each applicant is put into one of four bands based on need.
Another proposal would see anyone with "significant health or welfare needs" and "whose health is significantly affected by their current housing" automatically moved to band two, the council's second highest level of need.
Applicants must bid for housing through the council's social letting service, HomeChoice, where available council or housing association properties are made available.
According to the most recent council figures, the majority of applicants sit within band three but the majority of allocations are given to bands one and two.
Approximately 3% of applicants are categorised as band one – the group of highest priority.
