Letting agents need to beware detailed regulations contained in the Disability Discrimination Act 2005 which comes into force in December.
It imposes additional duties on landlords of premises that will be let, including residential property.
Now lawyers Williamson & Soden are warning that the legislation will not only affect businesses - buy to let investors could easily be caught out if they do not comply.
The law will impact not only on owners and managers, but also on managing and letting agents, since it will be an offence under the Act to treat disabled prospective tenants less favourably when marketing a property to let.
Also, landlords cannot include in the tenancy agreement any terms that would make it impossible or unreasonably difficult for a disabled person to use and derive benefit from the premises.
"Anyone who lets or manages property will need to prepare so that they understand their responsibilities and are in a position to comply," said solicitor and property specialist Louisa Jakeman.
"It's important for landlords and agents to understand that this legislation does not oblige them to remove or alter physical features to make properties suitable for disabled people.
"However, if an existing or prospective tenant with disabilities were to ask for auxiliary aids or services, landlords would have to take reasonable steps to lay these on and foot the bill."
It may, for example, be necessary to change taps and door handles or, to make life easier for a wheelchair user, alter the position of the door bell.
Mrs Jakeman says landlords may also have to provide non-permanent equipment or furniture: a tenant could not expect a landlord to install a walk-in bath, but would be within his rights to ask for a handrail to be fitted.
"Disabled access consultants recount horror stories about well-intended adaptations that disabled people simply cannot use, so I would urge landlords to seek advice as to how they can comply with these latest disability discrimination regulations before making any changes," added Mrs Jakeman.
