A new survey has revealed almost half of Queensland tenants are living in homes in need of repair and nearly two-thirds fear a repair request will result in a rent rise.

The report, conducted by the National Associations of Tenant Organisations, lays out alarming figures, with 8% of tenants being evicted at least once without explanation.

Tenants Queensland are calling for a restriction to rent increases to once a year, saying too many tenants are living in substandard housing.
