Three Common Reasons You May Need Retention Planning Permission

There are three common scenarios where people find themselves in need of retention planning permission.

1. Selling Your Property

Homeowners trying to sell their property may face challenges if certain parts of the main house, or other structures on the property, do not comply with planning regulations.

2. Bringing a Structure into Compliance with Planning Authority Rules

People who want to bring their property in line with Planning Authority rules may have to apply for retention permission to regularise unauthorised changes made to their property.

3. Receiving a Warning Letter from the Local Authority

If you have built a structure without planning permission, such as a garden cabin, and have received a warning letter from the local authority, you will need to apply for retention planning permission.

What Happens If Retention Permission Is Refused?

A retention application can be approved or refused. If it is refused, the decision can be appealed. Otherwise, to avoid any legal issues, work may be required on the property to return it to its original state, or to a state that has been approved.
