But while families are quick to share a roof, they are often slow to share the &#8220;fine print&#8221; of their daily expenses. In 2026, where insurance premiums have jumped by an average of <strong>$480<\/strong> and electricity concerns are at a decade high, the &#8220;handshake deal&#8221; on bills is a recipe for disaster.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The 2026 &#8220;Compliance Gap&#8221; (NSW Specific)<\/h3>\n\n\n\n<p>If you are in New South Wales (like our Randwick readers), you need to be aware of the <strong>Fair Trading and Building Legislation Amendment Bill 2026<\/strong>, passed in February. This bill was specifically designed to close loopholes in secondary dwelling construction.<\/p>\n\n\n\n<p>If you build an &#8220;informal&#8221; flat or convert a garage without meeting these new 2026 standards, you risk:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Insurance Voiding:<\/strong> Most standard home and contents policies will <strong>not<\/strong> cover a claim if the damage occurs in an unapproved or non-compliant dwelling.<\/li>\n\n\n\n<li><strong>Liability Exposure:<\/strong> If a family member (or their guest) is injured in a non-compliant space, you could be personally liable for astronomical medical costs.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">The &#8220;Hidden Costs&#8221; Conflict<\/h3>\n\n\n\n<p>In 2026, the cost of living isn&#8217;t just about the mortgage. Canstar\u2019s 2026 Consumer Pulse Report highlights that housing, groceries, and utilities are the top three financial stressors.
