How much contingency does a construction lender require?

    By Updated September 2026

    Most construction lenders require a contingency line of 5 to 10 percent of hard costs, and 10 percent is the standard for a first-time developer or a renovation with unknowns. The contingency sits inside the loan budget, is released only for approved overruns, and any unused portion reduces the loan at completion.

    What the contingency is

    A budget line held for costs that were not in the original scope: soil conditions, code changes, material price moves, and the items every project discovers after demolition. It is part of the loan, so it is funded by the lender and accrues interest only when drawn.

    Project typeTypical contingency required
    New construction, experienced sponsor5 percent of hard costs
    New construction, first project10 percent
    Renovation of an existing building10 to 15 percent
    Historic or occupied renovation15 to 20 percent

    Ranges vary by lender and project.

    Who controls it

    The lender. Contingency draws require a request explaining the overrun, usually with a change order, and the lender approves the reallocation. Some lenders release contingency freely for documented overruns; others hold it until other lines are exhausted. Ask which before you sign.

    Hard cost vs soft cost contingency

    Most contingencies are calculated on hard costs, meaning labor and materials. Soft costs, such as permits, design, and interest, usually carry their own cushion inside each line. Interest reserve shortfalls are a separate problem: the contingency generally cannot be used to pay interest.

    When the contingency runs out

    Overruns beyond the contingency are your cost. The lender will require you to deposit the shortfall before funding further draws, a condition called "loan in balance." Being out of balance stops draws until you cure it, which stalls the job. Keep reserves outside the loan for this reason.

    Using the contingency well

    1. Do not treat it as an upgrade fund. Finish upgrades come from your pocket.
    2. Submit change orders before the work, with the contractor's revised price.
    3. Track the contingency balance on every draw request.
    4. Bid the project with a real scope so the contingency is for surprises, not for items left out of the budget.

    At completion

    Unused contingency is not paid to you. It simply reduces the amount drawn, so the loan balance is lower and the interest was never charged on it. That is the good outcome.

    How much contingency does a construction loan need?
    Five to ten percent of hard costs for new construction, ten for a first project, and ten to twenty for renovations.
    Is the contingency part of the loan?
    Yes. It is a budget line funded by the lender and drawn only for approved overruns, so it accrues interest only when used.
    Can I use the contingency for upgrades?
    No. It is for unplanned costs. Upgrades and scope changes are your expense unless the lender approves a reallocation.
    What does loan in balance mean?
    The remaining loan funds plus your deposits must cover the remaining cost to complete. If not, the lender stops draws until you deposit the shortfall.
    What happens to unused contingency at the end?
    It is never drawn, so the loan balance is smaller. It is not paid out to you.
