A PILOT scheme to drive up housing conditions in Huddersfield is growing fast.
So far 47 landlords owning 150 properties have applied to sign up.
A further 250 landlords have inquired.
Kirklees Council's landlord accreditation is being tried out in Birkby, Fartown and Crosland Moor.
Its aim is to solve the problems of poor property conditions, poor management standards and empty and derelict properties.
Issues such as anti-social behaviour and community safety are also looked at.
Naeem Akhtar, of the council's accreditation team, said: "Considering the size of the pilot area, we have made really good progress and we are hoping to expand it to north Kirklees in April next year."
An agreement has already been established with Huddersfield University that only accredited landlords should be recommended to students.
Further possible developments include the introduction of a tenant accreditation scheme.
The landlord accreditation scheme was launched in May, with funding from the council, Neighbourhood Renewal Fund and the Office of the Deputy Prime Minister.
It was the result of two years of consultations with landlords.
Two meetings for landlords are taking place this month in Kirklees.
The first will be on Thursday at Fartown Community Centre on Wasp Nest Road.
The second will be at Dewsbury Town Hall on October 21.
Both run from 7pm to 9pm.
