        "text": "The biggest surprise costs are usually structural fixes, permit‑related changes, and upgrades you choose mid‑project. Many of these can be anticipated or at least budgeted for with a contingency.\n\nOlder homes and hillside lots are especially prone to unforeseen structural and utility issues. Design changes triggered by plan check or your own preferences also add time and money.\n\nKey factors:\n- Structural reinforcement, foundation work, or rot/termite repair\n- Utility upgrades (panel size, sewer capacity, HVAC changes)\n- Permit fees, plan‑check corrections, and required inspections\n- Finish upgrades you request after seeing the space framed\n\nBuild a 10–20% contingency into your budget and be disciplined about changes once construction starts. Ask your contractor upfront what kinds of surprises they most often see in homes like yours, and how they handle and price change orders. A transparent contractor will walk you through realistic “what if” scenarios before you sign."
