Mansfield District Council is set to accept funding of £405,474 to help drive up standards of private supported accommodation for tenants with complex needs.
It will also help the council scrutinise the amount of rent that providers charge.
The funding from the Department of Levelling Up, Housing and Communities is from its Supported Housing Improvement Programme.
In Mansfield, it will allow the council to introduce a supported housing accreditation scheme for providers, focusing on safeguarding vulnerable tenants, and enable it to employ three workers to enforce standards in supported housing for tenants who require extra support.
The scheme will run from 1 January 2023 until 31 March 2025.
Cllr Marion Bradshaw, Portfolio Holder for Community Safety, Housing and Wellbeing, said: "The legislation already exists to ensure that all rented housing meets certain standards, that landlords carry out essential repairs and that houses in multiple occupation adhere to the terms of their licences.
"What we have been short of is the manpower to enforce these standards. This funding will help to address that.
"It will also help to ensure that the taxpayer gets good value for money when it comes to the amount of rent that landlords can charge for supported housing, which is then paid for through housing benefits.
"There have been wide concerns that some unscrupulous landlords, with often very vulnerable tenants on housing benefit, are getting away with charging too much, knowing that their rent is paid for out of the public purse.
"This funding will help to ensure that what they are charging in rent is fair and commensurate with the quality of the accommodation and any extra services they are offering."
The three full time workers will be part of the council's Healthy Homes Hub project, focusing on supporting people with complex needs and improving poor property conditions.
They will inspect properties, ensuring compliance with legislative standards in regards to repairs, hazards and licensing requirements. They will also draw up required standards for offering supported housing which will focus on safeguarding residents, with detailed support plans and a pre-eviction protocol.
A delegated decision to officially accept the funding is due to be taken by the council's Portfolio Holder for Corporate and Finance on 15 December.
