Variations to residential building contracts

Contract variations are a common cause of home building disputes in NSW. Ensure variations are in writing and signed by both parties to avoid payment disputes.
{{ tag.label }} {{ tag.label }} $vuetify.icons.faTimes

When an owner or builder needs to adjust a building contract after it has been signed, there are key considerations and legal requirements to get the variation signed off and paid for. 

In this detailed article, you’ll learn all about contract variations and how they need to be managed from both sides. Key examples of common variations are supported by an overview of how HIA contracts cover you in this situation. This includes when emergency changes need to happen quickly. 

If you want to ensure you get paid promptly and reach a sound agreement with the owner when things change over the course of a building project, this is essential reading.
