Work done without a valid building warrant
It's an offence to carry out work which requires a building warrant without obtaining the relevant permission or to continue working on the project after the warrant has expired.
You may need to apply for a certificate or inspection if you've carried out work without a valid warrant. We may also take enforcement action (including issuing fines). It is also more than likely that you'll encounter problems when selling a property if the correct permission hasn't been obtained.
