        "text": "The biggest ADU risks are **cost overruns, delays, design/permit mistakes, and contractor issues**. Most horror stories trace back to rushed planning or unclear scopes.\n\nADUs are small but complex, with nearly all the systems of a full house crammed into a tight footprint. A small oversight in plans or permitting can create outsized delays or change orders.\n\nKey factors:\n- Underestimating total cost or skipping contingency\n- Incomplete plans that trigger repeated plan check corrections\n- Hidden site conditions (sewer depth, soil issues, utilities)\n- Unlicensed or under‑qualified contractors and poor contracts\n\nProtect yourself by getting detailed, stamped plans; a fixed‑scope, well‑written construction contract; and a realistic budget with a 10–20% contingency. Check licensing, insurance, and references before signing anything.\n\nExperienced ADU builders anticipate typical pitfalls and design your project to avoid surprises in the field."
