Lock in a comprehensive budget during pre-construction that includes design fees, permits, site work, construction, and a contingency reserve of 10 to 15 percent. The most effective budget protection is making all material and finish selections before construction begins, because mid-build changes are the leading cause of cost overruns. Regular budget reviews at each construction milestone also catch variances before they compound. As of May 2024, professional guidance during budgeting is especially valuable in Las Vegas where site-specific costs like caliche removal or extended utility runs can add significant unplanned expense.
