A man who converted a barn on his Mahana property into a habitable dwelling without a building consent has been fined $10,500.

Gary Francis Reilly appeared in the Nelson District Court on Wednesday facing a charge of carrying out work without a building consent.

A summary of facts showed that Reilly and his wife purchased the Mahana property in December 2016.

In November 2017, the Tasman District Council granted the couple a resource consent to build a barn on the property, on the basis it would not be a habitable building.
