Selective landlord licensing is gathering pace with more than 1,000 applications received so far.
Council bosses say they have issued 127 licences to housing landlords already –with more than 600 more waiting to be signed off and sent out.
The council brought selective licensing into effect last December as part of wider measures to deal with low housing demand, improve lives of tenants and landlord standards.
The scheme covers an estimated 4,850 properties in East and West Accrington and Church including more than 1,500 privately rented properties.
Deputy council leader Coun Clare Pritchard said many landlords are working hard to bring their properties up to standard - but there are 250 properties within the scheme area whose owners have not yet applied.
Speaking at an area council meeting last week, Coun Pritchard said: “The licences might not have been issued on all properties but people are working hard to bring them up to standard.
“People are running around frantically trying to bring the properties up to standard and that’s got to be an improvement.”
Spring Hill ward councillor Pam Barton said residents would soon begin to see the benefits of the scheme.
She told the meeting: “We fought long and hard to get selective licensing in Spring Hill above any other part of the borough. Lots of areas didn't get it and we got it here.
“I think over the next 12 months you will notice a dramatic difference.”
