Private home owners on council estates are letting the side down by dumping rubbish and failing to maintain their properties, it has been revealed.
Kirklees Council has clamped down on tenants who cause problems on its estates.
But now, owner occupiers who have bought their houses off the council are causing problems.
About 19% of council homes have been sold to tenants, with the rest still owned by the local authority.
Gerry Beamond, a neighbourhood services manager, said some home owners were breaking conditions which prevent them from certain actions, such as:
* Maintaining the garden around the property and keeping it free from weeds.
* Painting exterior woodwork and drainpipes every five years.
* Not carrying out a business on the property.
* Not placing billboards or ads on the house without permission.
* Sharing the cost of maintaining and repairing walls.
* Not overcrowding the property.
Mr Beamond said: "It's a problem on our estates and private estates as well.
"We are drawing it to the attention of councillors and asking what they want us to do and what can they do if these owner occupiers let the side down."
Where tenants breach their agreement with the council, the property can be repossessed.
But if the property is privately owned, the council has more limited powers.
Mr Beamond said Kirklees Neighbourhood Housing, which manages council properties, can seek injunctions, carry out work in default and recover the costs from the home owner.
He added that the expenditure of council cash and work involved in taking such actions would need to be examined, to see if they were good value for money in terms of costs and using officials' time.
